    Intended Use

    The Sol-Guard™ XtraThin Wall Safety Pull button blood collection set is a sterile, multi-sample, single-use fixed winged blood collection set intended for venipuncture to obtain blood specimens from patients. When used without the male Luer adaptor, the device allows the clinician to obtain blood sampling to the female hub with a syringe, if necessary or can be used for short-term (up to 2 hours), single infusions with consideration given to patient size and appropriateness for the solution being infused. The device is not to be left in place and should remain under the direct supervision of a clinician.

    The recommended use of the device is to activate the needle safety feature prior to removal from the venipuncture site. The retraction of the intravenous (IV) end of the needle aids in the prevention of accidental needlestick injury.

    Device Description

    Sol-Guard™ XtraThin Safety Pull-Button Blood Collection Set is a single-use, sterile, winged blood collection needle that can be used for blood collection and/or the short-term (up to 2 hours) infusion of intravenous fluids. The device is offered with butterfly needle set which has either 21-, 23- or 25-gauge needle with integral butterfly wings, offered in two different flexible tubing lengths of 178mm and 305mm, and a safety tube with tubing leading to a female luer connector. The female luer connector is optionally attached to a luer adapter, or luer adapter plus a tube holder.

    The device is designed with spring retractable needle technology that allows needle retraction after use to prevent needle stick injury and blood exposure. When the Button on the body of the butterfly is pulled back, the spring is released, and the needle is retracted into the clear plastic safety tube. In the activated position, the needle is completely enclosed within the clear plastic safety tube which guards against accidental needlesticks during normal handling and disposal.

    AI/ML Overview

    While the provided FDA 510(k) clearance letter and summary meticulously detail the substantial equivalence of the "Sol-Guard™ XtraThin Safety Pull-Button Blood Collection Set" to its predicate device, it does not contain information related to software, artificial intelligence (AI), diagnostic accuracy, or human reader performance.

    The document describes a physical medical device (a blood collection set) and its mechanical and material properties. The term "acceptance criteria" in this context refers to the bench and performance testing standards (e.g., ISO and ASTM standards) the device must meet to demonstrate its safety and effectiveness, particularly concerning the change in needle inner diameter.

    Therefore, I cannot provide an answer that includes:

    • A table of acceptance criteria for diagnostic performance or AI.
    • Sample sizes for a "test set" in an AI/diagnostic context.
    • Data provenance, expert qualifications, or adjudication methods for ground truth.
    • MRMC comparative effectiveness studies or effect sizes for human readers with AI assistance.
    • Standalone algorithm performance.
    • Ground truth types like expert consensus, pathology, or outcomes data.
    • Training set sample size or how its ground truth was established.

    The document is entirely focused on the physical characteristics and performance of a blood collection device, not on any kind of diagnostic or AI-driven system.

    If you are looking for information regarding acceptance criteria and studies for AI-powered medical devices, you would need a 510(k) submission or clearance letter for such a device. This document is for a conventional, non-AI medical device.

    ASTM F1929-15 (Detecting Seal Leaks in Porous Medical Package by Dye Penetration)Complied with ASTM F1929-15

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    The document primarily refers to compliance with international standards through non-clinical performance testing. It does not provide specific details on sample sizes for each non-clinical test conducted. The tests evaluate the physical, mechanical, chemical, and biological properties of the syringe. Given the nature of these tests, they are typically conducted in a controlled laboratory environment (prospective testing) to ensure adherence to the specified standards for medical devices. The country of origin of the data is not explicitly stated in this FDA submission document.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    This information is not applicable as the submission describes non-clinical performance testing against established engineering and biological standards, not clinical studies requiring expert consensus on medical conditions or interpretations. The "ground truth" here is adherence to specified parameters within recognized standards.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    This information is not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical trials where expert readers independently review medical images or patient data, and discrepancies are resolved. This submission details non-clinical laboratory testing.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    No MRMC comparative effectiveness study was done. The document explicitly states: "No clinical study is included in this submission." This device is a basic medical syringe, and such studies are not typically required for its clearance.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    This information is not applicable. The device is a physical medical instrument (syringe), not an AI algorithm or software. Therefore, there's no "standalone" algorithm performance to evaluate.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

    For the non-clinical performance testing, the "ground truth" is defined by the specifications and acceptable limits established within the cited international and industry standards. For example, for ISO 7886-1, the ground truth would be the defined force required for plunger operation, or the leakage limits. For biological compatibility tests, the ground truth would be the absence of toxicity or irritation as per ISO 10993 series.

    8. The sample size for the training set

    This information is not applicable. This is a submission for a physical medical device (syringe), not an AI/machine learning model that requires a training set.

    9. How the ground truth for the training set was established

    This information is not applicable for the same reason as point 8.

    Material/Design/IndicationsUnchanged from predicate
    Shelf Life (3 years)Verified in testing
    BiocompatibilityLeveraged from predicate
    SterilizationUnchanged from predicate

    2. Sample Size Used for the Test Set and Data Provenance

    • Sample Size: The document does not explicitly state the specific number of syringes used for each test (e.g., for critical dimensions, flow rate, compliance tests). It only refers to "testing per ISO 7886-2."
    • Data Provenance: Not explicitly stated, but based on the context of a 510(k) submission, this would be prospective testing conducted by the manufacturer, Sol-Millennium Medical Inc. The country of origin of the data is generally where the manufacturer performs their testing, which for Sol-Millennium Medical Inc. is based in Suwanee, Georgia.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

    Not applicable. This is a bench testing (non-clinical) submission involving a physical medical device (syringe). "Ground truth" in this context refers to standardized measurements and performance specifications outlined in ISO 7886-2, not expert consensus on diagnostic images or clinical outcomes.

    4. Adjudication Method for the Test Set

    Not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies, especially those involving human interpretation of data where consensus is needed to establish a "ground truth" or resolve disagreements. For bench testing against a standard like ISO 7886-2, objective measurements are taken, compared against predefined limits, and either pass or fail.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No, a MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic devices where human readers interpret data (e.g., radiologists reading images) and the AI aims to improve their performance. This submission is for a physical medical device (syringe) and focuses on engineering performance.

    6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

    Not applicable. This is for a physical medical device, not an algorithm or AI. The testing described is "standalone" in the sense that the syringe's performance is measured directly, not in conjunction with human interpretation of its output.

    7. Type of Ground Truth Used

    The "ground truth" for the test set is established by international standards and specifications, specifically ISO 7886-2:2020 (for use with power-driven syringe pumps) and ISO 7886-1:2017 (for manual use). These standards define acceptable ranges for dimensional requirements, flow rate error, pump forces, and syringe compliance.

    8. Sample Size for the Training Set

    Not applicable. There is no AI/algorithm component requiring a training set mentioned in this submission. This is a traditional medical device (syringe) bench test.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable, as there is no training set for an algorithm.

    It's important to note that the provided text is a 510(k) summary for a Sharps Injury Protection Device, specifically a blood collection set. The regulatory pathway for this type of device primarily focuses on demonstrating substantial equivalence to a predicate device, rather than a full-scale clinical study that establishes performance against strict, quantifiable clinical acceptance criteria (like sensitivity/specificity for a diagnostic AI). Therefore, the "acceptance criteria" here are largely related to bench testing, biocompatibility, and usability demonstrating equivalent safety and effectiveness to the predicate, particularly regarding the safety mechanism.

    The documentation focuses on comparing the subject device to a predicate device (BD Vacutainer® UltraTouch™ Push Button Blood Collection Set, K153309) and demonstrating that any differences do not raise new questions of safety or effectiveness.


    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria for this device are largely derived from recognized international standards and a demonstration of equivalence to the predicate device. The performance data presented are primarily from bench testing, biocompatibility testing, and simulated usability studies.

    Acceptance Criteria CategorySpecific Acceptance Criteria (based on standards/equivalence to predicate)Reported Device Performance (from studies/tests)
    Safety Mechanism Activation & EffectivenessActivation: Mechanism for withdrawing the needle must function reliably. Needlestick Prevention: Must adequately prevent accidental needlestick injuries post-use. Jammed Retraction: Resistance to jammed retraction. Unlocking Resistance: Safety shield must resist unintentional unlocking.All tests (Forces for Activation, Simulated "in-Vein" Needle Retraction, Simulated Jammed Retraction, and Safety Shield Unlocking Resistance) and a Simulated Usability Study demonstrated that the "Pull" motion activates the safety mechanism effectively and provides the same protection as the predicate device.
    Material BiocompatibilityNo adverse biological reactions (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemocompatibility).Passed all biocompatibility tests per ISO 10993 (Cytotoxicity, Sensitization, Intracutaneous Reactivity, Pyrogenicity, Acute systemic toxicity, Hemocompatibility).
    Sterilization & Sterility AssuranceSterility Assurance Level (SAL) of 10^-6; acceptable residuals (EO/ECH); non-pyrogenic.Sterilization validated per ISO 11135, achieving an SAL of 10^-6. Met applicable acceptance criteria for EO and ECH residuals per ISO 10993-7 and pyrogenicity per USP . Bacterial endotoxin testing conducted on every lot in manufacturing to meet 20EU/device.
    Physical and Performance CharacteristicsAdherence to relevant ISO standards for needles, tubing, connectors (e.g., dimensions, flow rates, connector integrity). Acceptable particulate matter levels.Conformance with ISO 7864, ISO 6009, ISO 8536-4, ISO 9626, ISO 80369-7, ISO 80369-20, ISO 20696, ISO 23908. Particulate matter testing met USP acceptance criteria.
    Shelf-LifeDevice maintains safety and effectiveness over its claimed shelf-life.Real-time and accelerated shelf-life testing per ASTM F1980-16 demonstrated no impact on safety or effectiveness for a 3-year shelf-life.
    Packaging IntegrityMaintains sterile barrier.Sterile Barrier Packaging testing (Peeling force per ASTM F88/F88M, Clean Peel per ISO 11607-1, and ASTM F1929 for Dye Penetration Test) performed.
    Shipping IntegrityDevice and packaging integrity maintained during shipping.Simulated Shipping per ISTA 3A conducted.

    2. Sample Size Used for the Test Set and Data Provenance

    Given the nature of a 510(k) submission for a sharps injury protection device, formal "test sets" of patient data (as one would see for an AI/diagnostic device) are not typically used. The "test set" here refers to:

    • Physical device samples used for bench testing (e.g., for force measurements, retraction tests, flow rates). The exact number of samples for each test is not specified in the summary but would be detailed in the full test reports.
    • Physical device samples used for biocompatibility testing (extracted materials).
    • Volunteer participants for the "Simulated Usability Study." The number of participants is not specified.

    Data Provenance: The studies are prospective bench and usability studies conducted by the manufacturer (Sol-Millennium Medical, Inc.). The country of origin for the data is implicitly the location where the manufacturer's testing facilities are based.


    3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

    For this type of device, "ground truth" is not established by clinical experts in the sense of diagnosing a condition. Instead, the "ground truth" or "objective criteria" are defined by:

    • International standards (ISO, ASTM, USP): These standards define measurable physical and chemical properties and performance benchmarks.
    • Engineering specifications and regulatory requirements: Defining what constitutes "safe" and "effective" operation of the device's mechanisms.
    • Predicate device performance: Used as a benchmark for equivalence.

    Therefore, there wasn't a panel of "experts" (e.g., radiologists) used to establish a clinical ground truth for a test set. Rather, the "ground truth" is based on established engineering principles, validated test methods, and regulatory precedents. Individuals involved would include:

    • Engineers and Quality Control personnel: Qualified to design, execute, and interpret bench tests in accordance with relevant standards.
    • Toxicologists/Biocompatibility Specialists: Qualified to interpret biocompatibility test results.
    • Regulatory Affairs Specialists: Qualified to interpret regulatory requirements and predicate device information.

    4. Adjudication Method for the Test Set

    Adjudication methods like "2+1" or "3+1" are relevant for subjective interpretations by multiple human readers (e.g., in medical image analysis). For this device, where "ground truth" is based on objective measurements and adherence to standards, such a medical adjudication method is not applicable.

    The "adjudication" is inherent in the validation of the test methods themselves (e.g., ensuring they are robust and reproducible) and the interpretation of results against pre-defined acceptance criteria derived from standards or engineering specifications. Any discrepancies in test results would be handled through and internal quality system's investigation and retesting procedures.


    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No MRMC study was conducted or is applicable for this type of device.

    MRMC studies are typically performed for AI-assisted diagnostic devices to assess how AI impacts the diagnostic performance (e.g., accuracy, sensitivity, specificity) of human readers or to compare reader performance with and without AI assistance. This device is a blood collection set with a safety mechanism, not a diagnostic tool requiring human interpretation of complex medical data.

    The "human factor" component was addressed through a "Simulated Usability Study" to ensure the safety mechanism is intuitive and effective for users, but this is distinct from an MRMC study.


    6. Standalone (Algorithm Only) Performance

    Not applicable. This device is a physical medical device, not a software algorithm. Therefore, there is no "standalone" algorithm-only performance to evaluate. The "standalone" performance for this device is its physical and mechanical performance as evaluated through bench testing.


    7. Type of Ground Truth Used

    The "ground truth" for this device's evaluation is primarily based on:

    • Objective physical measurements: Forces, dimensions, flow rates, particulate counts, sterility (measured via biological indicators/analytical tests).
    • Adherence to recognized industry standards: ISO, ASTM, USP, which define performance benchmarks and test methodologies.
    • Biocompatibility test results: Based on standardized biological assays.
    • Simulated use studies: Observing user interaction with the device under controlled, non-clinical conditions.

    It does not involve expert consensus on clinical diagnoses, pathology, or patient outcomes data directly for determining the device's classification or performance in the 510(k) context. The device's safety mechanism aims to prevent adverse outcomes (needlestick injuries), and its effectiveness is demonstrated through mechanical reliability, not by analyzing patient outcome data from a clinical trial.


    8. Sample Size for the Training Set

    Not applicable. As this is a physical medical device and not an AI/machine learning algorithm, there is no "training set" of data in the computational sense. The device's design is based on engineering principles and iterative development, not on training a model with data.


    9. How the Ground Truth for the Training Set Was Established

    Not applicable, as there is no training set. The design and manufacturing processes for the device are governed by quality management systems (e.g., 21 CFR Part 820 Quality System Regulation). Performance characteristics are verified through design validation and verification activities, not machine learning training.

    Important Note: The document consistently states "met the appropriate requirements" or "Protocol and Report successfully completed" for each test, implying that the device successfully passed all established criteria within those tests/standards. The specific quantitative acceptance thresholds are not detailed in this summary document but would be part of the full test reports (e.g., PRJ001_096).


    Here's the remaining information based on the provided text:

    2. Sample size used for the test set and the data provenance

    • Sample Size: Not explicitly stated for each test, but a "Simulated Use Study with Nurse Evaluators" was conducted, implying human interaction with the device. For the accelerated aging tests, product testing occurred at "time 0, years 1, 2 and 3," which points to batches of devices being tested.
    • Data Provenance: Not explicitly stated (e.g., country of origin). The studies appear to be conducted by the manufacturer or their contracted laboratories as part of their premarket submission. The regulatory context (FDA 510(k) submission in the USA) implies the data is generated for US regulatory standards. All nonclinical tests are listed, indicating these are internal or contract lab results rather than clinical data from human subjects.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    • This question is largely not applicable in the context of this device and report. The "ground truth" for a blood collection needle in this submission is established by adherence to recognized engineering and biocompatibility standards (e.g., ISO, ASTM). Performance is measured against physical, chemical, and biological criteria, not against expert medical interpretations of complex images or patient outcomes in the same way an AI diagnostic device would be.
    • A "Simulated Use Study with Nurse Evaluators" was conducted, indicating that nurses (experts in using such devices) evaluated the device. However, the number and specific qualifications (beyond "nurse") are not detailed, and their role was likely to assess usability and safety features in a simulated environment, rather than establishing a "ground truth" diagnosis.

    4. Adjudication method for the test set

    • Not applicable in the context of this submission. Adjudication methods like 2+1 or 3+1 panels are typically used to establish a definitive "ground truth" when interpreting subjective data (e.g., medical images). This submission focuses on objective engineering, material, and biological performance criteria against established standards, where the test results themselves constitute the "ground truth" of performance.

    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    • No, an MRMC comparative effectiveness study was not done. This device is a physical medical instrument (blood collection needle), not an AI diagnostic tool. Therefore, the concept of "human readers improving with AI assistance" is not relevant.

    6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done

    • Not applicable. This is a physical medical device, not an algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

    • For this device, the "ground truth" for performance is based on fulfilling the requirements of International Standards (ISO, ASTM) and internal validated test protocols. This includes:
      • Engineering specifications (e.g., flow rate, puncture force, needle dimensions).
      • Material properties (e.g., chemical compatibility, strength).
      • Safety features physical performance (e.g., pulling force for shield activation, locking mechanism).
      • Sterility assurance levels.
      • Biocompatibility testing results (e.g., cytotoxicity, hemolysis).
      • Packaging integrity (e.g., seal strength, transit simulation).
    • The Simulated Use Study with Nurse Evaluators provides practical "ground truth" for usability and effective activation of the safety mechanism by intended users.

    8. The sample size for the training set

    • Not applicable. This is a physical medical device, not a machine learning algorithm requiring a training set.

    9. How the ground truth for the training set was established

    • Not applicable. As above, no training set for an algorithm is involved.

    Intended Use

    The 0.5ml Sol-Care™ Retractable Safety Syringe is used to inject fluids into, or withdraw fluids from, the body. In addition, the 0.5ml Sol-Care™ Retractable Safety Syringes is designed to aid in the prevention of needle stick injuries.

    Device Description

    The 0.5ml Sol-Care™ Retractable Safety Syringe with Fixed Needle is a sterile, single use, safety syringe with a fixed needle that is used to inject fluids into, or withdraw fluids from, the body. The 0.5ml Sol-Care™ Retractable Safety Syringe with Fixed Needle is also designed to aid in the prevention of needle stick injuries. The retractable piston syringe is a plastic disposable syringe made of the following components: Barrel, Plunger, Stopper, Cannula, Locking Ring, Needle Cap, O-Ring, Protective Cap. After use, the health care professional firmly pushes the plunger past the zero line to engage the safety mechanism. Once the safety mechanism is engaged, pulling back the plunger causes the needle to be retracted into the barrel. In this position against the flange, lateral pressure on the plunger results in a controlled fracture of the plunger. Both the syringe and the plunger are discarded into a sharps container. The 0.5ml Sol-Care™ Retractable Safety Syringe with Fixed Needle are sterilized by Ethylene Oxide and supplied sterile in a blister pack or tray pack.

    AI/ML Overview

    The provided document is for a medical device called "0.5ml Sol-Care™ Ret retractable Safety Syringes" and primarily focuses on its substantial equivalence to a predicate device for FDA clearance. Therefore, the information requested about acceptance criteria and study details related to performance metrics like sensitivity, specificity, or AI assistance is not typically found in this type of submission for a physical medical device.

    However, I can extract information regarding performance in terms of meeting established standards for the device. The document explicitly states that the device met the requirements of several ISO standards.

    Here's the closest representation of the requested information based on the provided text:

    1. A table of acceptance criteria and the reported device performance

    Acceptance Criteria (Standard Reference)Reported Device Performance
    ISO 7886:1993, Sterile Hypodermic Syringes for Single UseMet the appropriate requirements (implies compliance with all specifications within the standard, e.g., sterility, fluid tightness, material properties, plunger operation, scale markings, etc. specific to single-use hypodermic syringes).
    ISO 7886-4:2006, Sterile Hypodermic Syringes for Single Use Syringes with re-use prevention featureMet the appropriate requirements (implies compliance with additional specifications for safety features preventing re-use, likely related to the retraction mechanism and its function).
    ISO 11607-1,-1:2006, Packaging for terminally sterilized medical devicesMet the appropriate requirements (implies compliance with standards for maintaining sterility of the packaged device, integrity, and labeling).
    ISO 11135:2007, Medical Apparatus Epoxy Ethane Sterilization Confirmation and Routine ControlMet the appropriate requirements (implies successful sterilization using Ethylene Oxide and confirmation of its effectiveness).
    ISO 10993-1:2006, Biological evaluation of medical devices Part 1: Evaluation and testingMet the appropriate requirements (implies successful completion of biocompatibility tests such as Cytotoxicity, Sensitization, Irritation, Systemic Toxicity, and Hemolysis tests without adverse reactions).
    ISO 9626:1991, Stainless Steel needle tubing for the manufacture of medical devicesMet the appropriate requirements (implies the needle tubing conforms to the specified properties for stainless steel medical device needles).
    All product specifications and requirementsThe device has been tested and found to meet all product specifications and requirements.

    Regarding the other points, the document states or implies the following limitations:

    • 2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): The document does not specify sample sizes for each test in the ISO standards, nor the country of origin or whether the studies were retrospective or prospective. It only generically states that tests were conducted.
    • 3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. For these types of device performance tests (e.g., sterility, material strength, retraction mechanism function), a "ground truth" established by experts in the clinical or diagnostic sense is not relevant. The ground truth is defined by the objective pass/fail criteria of the engineering and biocompatibility standards.
    • 4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. The tests against ISO standards typically involve objective measurements or pass/fail observations, not subjective adjudication methods.
    • 5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This is a physical medical device (safety syringe), not an AI/software-based diagnostic or imaging device. There are no "human readers" or "AI assistance" involved in its intended use.
    • 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable, as detailed above.
    • 7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): The "ground truth" implicitly referred to is the objective criteria and methodologies defined within the cited ISO standards for device performance and safety (e.g., successful retraction, material biocompatibility limits, sterility assurance levels).
    • 8. The sample size for the training set: Not applicable. This device does not involve a "training set" in the context of machine learning.
    • 9. How the ground truth for the training set was established: Not applicable.

    In summary, the document details a regulatory submission for a physical medical device. Its "acceptance criteria" and "study" revolve around demonstrating compliance with established international standards for the design, manufacturing, and biological safety of such devices, rather than clinical performance metrics of an AI or diagnostic tool.
