    AI/ML Overview

    The provided text describes the SpiroSphere, a device for measuring lung function, and its substantial equivalence to a predicate device (SpiroPro). However, it does not contain the detailed information required to answer your specific questions about acceptance criteria and a study proving the device meets them.

    The document is a 510(k) summary for premarket notification to the FDA. It focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than providing the detailed clinical or performance study results you're asking for.

    Here's a breakdown of why the requested information is absent:

    • Acceptance Criteria and Reported Device Performance (Table): The document states adherence to ATS/ERS standards (2005) for spirometry accuracy and precision and lists various parameters measured (FEV1, FVC, PEF, etc.). However, it does not provide a specific table of acceptance criteria (e.g., +/- x% accuracy) or numerical reported device performance against those criteria. It only generally states that "Tests were performed to confirm that the SpiroSphere meets the recommendations for accuracy and precision for Spirometry of the American Thoracic Society (ATS) according to ATS/ERS standards 2005."
    • Sample Size, Data Provenance, Ground Truth Experts, Adjudication Method, MRMC Study, Standalone Performance, Training Set Sample Size/Ground Truth: These details are typically found in a dedicated clinical or performance study report, which is not included in this summary. The 510(k) summary only mentions general verification and validation activities and conformance to standards.

    In summary, based only on the provided text, I cannot complete the table or answer the specific questions about the study details because that level of detail is not present in this FDA 510(k) summary.

    The document discusses:

    • Device Name: SpiroSphere
    • Predicate Device: SpiroPro (K000648) and SpiroPro with BT (K092324)
    • Intended Use/Indications for Use: To measure inspiratory and expiratory lung function parameters in adults and children aged 4 years and older, usable by physicians in office or hospital.
    • Technological Characteristics: Uses a pneumotachograph (Lilly Type) for pressure to flow conversion, measures various parameters (FEV1, FVC, PEF, FEF25-75, VC, IC, ERV) conforming to ATS/ERS Spirometry Standards (2005).
    • Testing Mentioned: Software verification and validation (IEC 62304), Risk analysis (ISO 14971), electrical safety (IEC 60601-1:2012), EMC (IEC 60601-1-2:2014), wireless technology (FDA Guidance 2013), Human Factors/Usability (IEC 62366), Biocompatibility (ISO 10993-1:2009, ISO 18562:2017), Cybersecurity (FDA Guidance 2014), Reprocessing (FDA Guidance 2015).

    To answer your questions thoroughly, a complete performance study report would be required, which typically contains the specific data and methodologies.

    MEDIKRO SPIROSTAR, M929 Medikro Spirostar USB and M921 Medikro SpiroStar DX

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    Medikro Spirometer is a device that measures lung air volume and airflow rate for pulmonary disease diagnosis and screening. These measurements provide information about a patient's pulmonary function which may be compared with normal values or the patient's previous values.

    The device is designed for

    • . adult and pediatric patients,
    • hospital and clinic use only.
    Device Description

    Medikro® SpiroStar spirometer runs on a personal computer with Microsoft Windows operating systems.

    Medikro® SpiroStar spirometer unit is connected to PC via USB port (USB model) or via serial port (DX model). SpiroSafe disposable flow transducer is connected to the spirometer unit via pressure tube. A nose clip is used to prevent air flow from nose during measurements. Optional calibration syringe is used for recommended daily volume calibrations.

    Medikro® SpiroStar spirometers are used to measure lung air volume and airflow rate. Medikro® Spirometry Software is used to perform the measurement and calculate the measurement volume based on chosen reference value. The reference value is based on patient's gender, race and age. User can analyze the results in different presentations and create a final report based on the results and patient information.

    The spirometers take all the power that it needs from the USB or serial port, so no other external or internal power supply is needed.

    AI/ML Overview

    The Medikro® SpiroStar device, including models M929 (USB) and M921 (DX), is a diagnostic spirometer intended to measure lung air volume and airflow rate for pulmonary disease diagnosis and screening. The device's performance was evaluated against the American Thoracic Society (ATS) recommendations for spirometers to demonstrate substantial equivalence to predicate devices.

    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 explicitly state the sample size for the test set in terms of number of patients or spirometry maneuvers. Instead, it refers to "American Thoracic Society (ATS) 24 standard waveforms test". This suggests the use of a standardized set of simulated waveforms rather than patient data. The provenance of these standard waveforms is the American Thoracic Society. It is a retrospective evaluation against established synthetic data.

    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)

    The ground truth for this study was established by the "American Thoracic Society (ATS) 24 standard waveforms". These are not "expert-generated ground truth" in the typical sense of a clinical interpretation, but rather predefined, standardized synthetic waveforms with known, precise values for spirometry parameters. Therefore, no human experts were involved in establishing the "ground truth" for the test set in this context.

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

    Not applicable. The test involved comparing the device's measurements against the known values of the ATS 24 standard waveforms. This is a direct measurement comparison, not an expert-based adjudication process.

    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 performance study for a diagnostic spirometer, which directly measures physiological parameters. It is not an AI-based interpretation system, and therefore, no MRMC study or evaluation of human reader improvement with AI assistance was performed.

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

    Yes, a standalone performance evaluation was conducted. The Medikro® SpiroStar units (USB and DX) were tested directly against the ATS 24 standard waveforms to determine if their measurements met the specified recommendations. This is an algorithm-only (device-only) performance assessment.

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

    The type of ground truth used was standardized synthetic waveforms with known, precise values, specifically the American Thoracic Society (ATS) 24 standard waveforms.

    8. The sample size for the training set

    The document does not mention a training set. This type of device (diagnostic spirometer) typically relies on engineering and physiological principles for its design and calibration, rather than machine learning models that require training data. The testing described is a validation of the device's accuracy against established standards.

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

    Not applicable, as no training set or machine learning components are described in the context of this device's performance evaluation.

    SPINNING SPIROS, MODEL CH-2000

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The Spiros is a single use, sterile, non-pyrogenic, swab-able, bidirectional valve device intended for use as an accessory to an Intravascular Administration Set. The Spiros provides access for the administration of fluids from a container to a patient's vascular system through the administration needle or catheter (which is inserted into the vein or artery).

    Device Description

    The Spinning Spiros is a closed connector which is compatible with and used to access, standard female luers and known needle-free connectors. The Spinning Spiros is a passively closed design which will prevent the leakage of fluid or ingress of air when in the inactivated (resting) state. When activated the luer is an open twoway conduit for fluid flow. The Spinning Spiros is an accessory to an IV administration device including tubing sets and syringes, such that an integral female luer is used to connect to such devices.

    AI/ML Overview

    The provided text describes a 510(k) summary for the "Spinning Spiros" device. This is a regulatory submission for a medical device seeking clearance based on substantial equivalence to a predicate device, not typically a study reporting detailed performance metrics and acceptance criteria in the way a clinical trial or a formal performance study would.

    Therefore, the information requested in your prompt (especially regarding sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, and training set details) is not present in the provided document. This type of regulatory document focuses on demonstrating equivalence to an already marketed device rather than presenting novel performance study data in detail.

    However, based on the snippet: "ICU Medical Spinning Spiros closed male luer device has been tested post sterilization and passed all acceptance criteria. The Spinning Spiros closed mate luer meets the functional claims and intended use as described in the product labeling and is safe and effective in terms of substantial equivalence as the predicate device described in this document," we can infer the general nature of the acceptance criteria and the study's conclusion, even if the specifics are not given.

    Here's a breakdown of what can be extracted and what is missing based on your prompt:


    1. Table of acceptance criteria and the reported device performance:

    Acceptance Criteria (Inferred)Reported Device Performance (Inferred)
    Functional equivalence to predicate device (K070532 - Spiros)"The Spinning Spiros... is equivalent to the predicate device because it does not modify the claim."
    Prevention of fluid leakage in inactivated state"The Spinning Spiros is a passively closed design which will prevent the leakage of fluid..."
    Prevention of air ingress in inactivated state"The Spinning Spiros is a passively closed design which will prevent... ingress of air when in the inactivated (resting) state."
    Open two-way conduit for fluid flow when activated"When activated the luer is an open two-way conduit for fluid flow."
    Compatibility with standard female luers and needle-free connectors"The Spinning Spiros is a closed connector which is compatible with and used to access, standard female luers and known needle-free connectors."
    Single use"The Spiros is a single use..."
    Sterile"The Spiros is a... sterile..."
    Non-pyrogenic"The Spiros is a... non-pyrogenic..."
    Swab-able"The Spiros is a... swab-able..."
    Bi-directional valve function"The Spiros is a... bidirectional valve device..."
    Mechanical integrity post-sterilization"ICU Medical Spinning Spiros closed male luer device has been tested post sterilization and passed all acceptance criteria."
    Safety and effectiveness"The Spinning Spiros closed mate luer... is safe and effective in terms of substantial equivalence..."
    No accidental back-off from syringe"The spin collar adds the feature that the Spinning Spiros won't accidentally back off of a syringe."

    Missing Information (Not Available in the Provided Text):

    1. Sample size used for the test set and the data provenance: This information is not provided. The document states "has been tested," but no specifics on sample size or whether it was internal company testing, external, etc., are given.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable or not provided. This device is not one that typically requires expert interpretation for "ground truth" in the way an imaging AI model would. It relates to functional and material testing.
    3. Adjudication method: Not applicable or not provided.
    4. 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 not an AI-assisted device.
    5. 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.
    6. The type of ground truth used: For a physical device like this, "ground truth" would be established by physical measurements, functional tests (e.g., flow rate, leak tests, force to connect/disconnect), material testing, and sterilization validation, all performed against engineering specifications and relevant ISO/ASTM standards. The document only generically states "passed all acceptance criteria" and "meets the functional claims."
    7. The sample size for the training set: Not applicable. This is not an AI/machine learning device.
    8. How the ground truth for the training set was established: Not applicable.

    Summary of the Study (Inferred from the document):

    The "study" referenced is likely a series of internal verification and validation tests (V&V) conducted by ICU Medical, Inc. on the Spinning Spiros device. These tests would have been designed to ensure the device met its design specifications and functional requirements, and to demonstrate substantial equivalence to the predicate device (Spiros, K070532). The tests would have included evaluating the device's mechanical integrity (especially after sterilization), fluidic properties (leakage, flow), compatibility with standard luers, and the specific feature of the spinning collar preventing accidental disconnection. The conclusion of these internal studies was that the device met all acceptance criteria, functional claims, and intended uses, deeming it safe and effective and substantially equivalent to its predicate. The specifics of these tests (e.g., protocols, sample sizes, detailed results) are typically found in the full 510(k) submission, not in the publicly available summary.

    AI/ML Overview

    The provided text does not contain detailed information about specific acceptance criteria and a study proving the device meets them in the format requested.

    The document is a Special 510(k) Summary for the Spiros™ Closed Male Luer, and it focuses on demonstrating substantial equivalence to a predicate device rather than comprehensive performance studies with acceptance criteria as typically found in medical device approvals based on clinical trials or extensive engineering verification.

    Here's a breakdown of what can be extracted and what is missing, based on the provided text:

    Acceptance Criteria and Device Performance:

    The document states: "The Spiros™ closed male luer device has been tested post sterilization and passed all acceptance criteria." However, it does not list what those specific acceptance criteria are, nor does it report specific device performance metrics against those criteria. It only makes a general statement of compliance.

    Missing Information (Not found in the provided text):

    • A table of acceptance criteria and reported device performance.
    • Sample size used for the test set.
    • Data provenance (country of origin, retrospective/prospective).
    • Number of experts used to establish ground truth.
    • Qualifications of experts.
    • Adjudication method.
    • If a multi-reader multi-case (MRMC) comparative effectiveness study was done.
    • Effect size of human reader improvement with AI vs. without AI assistance.
    • If a standalone (algorithm only) performance study was done.
    • Type of ground truth used (pathology, outcomes data, expert consensus, etc.).
    • Sample size for the training set.
    • How ground truth for the training set was established.

    Information Extracted from the Text:

    Since the detailed information for the requested table and study details is not present, I will summarize the general statements made in the document regarding testing and equivalence.


    Summary of Device Evaluation (Based on provided text)

    Device Name: Spiros™ Closed Male Luer

    1. Table of Acceptance Criteria and Reported Device Performance:

    Acceptance CriteriaReported Device Performance
    Not explicitly stated in the document"passed all acceptance criteria"
    Functional Claims"meets the functional claims"
    Intended Use"meets the intended use as described in the product labeling"

    Note: The document makes general statements about passing acceptance criteria and meeting claims but does not provide specific quantitative or qualitative criteria or corresponding performance data.

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

    • Sample Size: Not specified.
    • Data Provenance: Not specified. (The document mentions testing "post sterilization," implying laboratory or engineering testing, not clinical data.)

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

    • Number of Experts: Not applicable/Not specified.
    • Qualifications of Experts: Not applicable/Not specified.
      This type of evaluation is not relevant as this is a device for fluid administration, not one requiring expert human interpretation of data (like medical images).

    4. Adjudication method for the test set:

    • Not applicable/Not specified.

    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. This type of study is not relevant for this device. The Spiros™ is a physical medical device (closed male luer) for intravenous fluid administration, not an AI-powered diagnostic or assistive technology that would involve human readers or AI algorithms for interpretation.

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

    • No. Not applicable as this is a physical device, not an algorithm.

    7. The type of ground truth used:

    • The concept of "ground truth" as typically applied to diagnostic or AI devices is not explicitly detailed here. The evaluation of this device would involve engineering and performance testing against established physical and functional standards (e.g., fluid leakage tests, pressure resistance, sterility, biocompatibility), rather than a "ground truth" derived from expert consensus, pathology, or outcomes data in a clinical sense.

    8. The sample size for the training set:

    • Not applicable/Not specified. (This device does not involve a "training set" in the context of machine learning or AI.)

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

    • Not applicable/Not specified.

    Study that Proves the Device Meets the Acceptance Criteria:

    The document states: "The Spiros™ closed male luer device has been tested post sterilization and passed all acceptance criteria."

    • Nature of the Study: Based on the context of a 510(k) for a physical medical device (intravascular administration set accessory), the "study" referred to would be a series of verification and validation (V&V) tests, including:

      • Performance testing: To ensure the device functions as intended (e.g., preventing leakage, allowing fluid flow when activated, resistance to pressure).
      • Biocompatibility testing: To ensure materials are safe for patient contact.
      • Sterilization validation: To confirm the device can be consistently sterilized.
      • Shelf-life testing: To ensure stability over time.
      • Material compatibility testing: Especially given the change in polycarbonate vendor and the addition of an O-ring.
    • Evidence of Meeting Criteria: The document asserts that the device "passed all acceptance criteria" and "meets the functional claims and intended use." The basis for this claim is the "testing post sterilization." This aligns with the requirements for demonstrating substantial equivalence for a Class II device.

    • Specifics Missing: The document does not provide details of which specific tests were conducted, what the passing thresholds were, or what the actual results recorded were for each test. This level of detail is typically contained in the full 510(k) submission, not necessarily in the summary provided for the public. The focus of the provided summary is to highlight substantial equivalence to an existing predicate device, primarily through comparing features and stating that performance testing confirmed safety and effectiveness.

    AI/ML Overview

    This document is a 510(k) premarket notification decision letter from the FDA for the SpiroSoft device. It does not contain information about acceptance criteria or a study proving that the device meets such criteria. The letter primarily states that the device is substantially equivalent to legally marketed predicate devices and can therefore be marketed.

    Therefore, I cannot provide the requested information based on the text provided. Questions 1 through 9 cannot be answered.

    SPIROSAFE FILTER

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    To filter possible bacteria and viruses from the patient exhalation when performing pulmonary function testing

    Device Description

    A disposable bacterial/viral filter used in pulmonary function testing

    AI/ML Overview

    The provided text describes the SpiroSafe Filter, a disposable bacterial/viral filter for pulmonary function testing. The study demonstrates the device's substantial equivalence to a predicate device (PDSI KoKo Filter - K914272) based on performance criteria.

    Here's a breakdown of the requested information based on the provided text:

    1. Acceptance Criteria and Reported Device Performance

    Acceptance CriteriaIntended device Performance (SpiroSafe Filter)Predicate Device Performance (PDSI KoKo Filter)
    Bacterial Efficiency>99%99.99%
    Viral Efficiency>99%99.98%
    Resistance to Airflow>1.5 cmH2O/L/Sec. @ 12/L/Sec.0.9 cmH2O/L/Sec. @ 12/L/Sec.
    Use as bacterial/viral filterYesYes
    Use during pulmonary function testYesYes
    Single patient useYesYes
    Housing material - Impact PolystyreneYesYes
    Filter MediaElectrostatFiltrete

    Note: While the text doesn't explicitly state "acceptance criteria", the comparison table to the predicate device implies that the performance characteristics of the predicate serve as the benchmark for substantial equivalence. The SpiroSafe Filter meets or exceeds the critical performance aspects (bacterial/viral efficiency) of the predicate. The resistance to airflow value for the predicate is 0.9, and the intended device is ">1.5", which seems to indicate the SpiroSafe filter exceeds the predicate in this metric; however, for resistance, lower is generally better. This could be a typo in the document or interpreted differently. Assuming the acceptance criteria aligns with being "comparable or better" than the predicate, the device broadly meets this.

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

    The document does not specify the sample size used for the performance testing shown. It is simply presenting performance data.

    The data provenance is not explicitly stated (e.g., country of origin, retrospective/prospective). This appears to be a direct presentation of product specifications rather than a clinical study.

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

    This information is not applicable. The device's performance is measured against technical specifications, not subject to expert interpretation for ground truth.

    4. Adjudication Method for the Test Set

    This information is not applicable as there is no mention of a human-in-the-loop assessment or expert review for adjudication.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

    No, an MRMC comparative effectiveness study was not done. This device is a physical filter, and the evaluation is based on its physical and filtering properties, not on diagnostic accuracy requiring human reader interpretation.

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

    Yes, in a sense, a "standalone" performance assessment was done. The performance metrics (bacterial efficiency, viral efficiency, resistance to airflow) are inherent to the device itself and do not involve human interaction beyond conducting the tests. The results presented are solely based on the device's intrinsic characteristics.

    7. The Type of Ground Truth Used

    The ground truth used is based on measured physical and performance characteristics (e.g., bacterial efficiency percentage, viral efficiency percentage, resistance to airflow in cmH2O/L/Sec.). This is analogous to laboratory testing/engineering specifications.

    8. The Sample Size for the Training Set

    This information is not applicable as there is no mention of a "training set" in the context of this device. The evaluation is focused on the manufactured product's specifications rather than a machine learning model.

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

    This information is not applicable as there is no mention of a "training set" or a machine learning context.
