The Kawasumi Multiple Sample Adapter with Pr-Attached Holder (MBCH) is a sterile, non-invasive device used for connection with a female luer system and non-needle devices in order to collect blood specimen to blood collection tube.
The Kawasumi Multiple Sample Adapter with Pre-Attached Holder (MBCH) is a sterile, singleuse device consisting of a plastic holder with a non-patient contacting stainless steel cannula covered with a rubber sheath and a male luer adapter which is attached into the holder. This device is used to collect blood specimen by connecting to female luer connectors of vascular access devices such as peripheral, central catheter, Huber needle, etc. As this device can be connected to various devices with female luer adapter, it is called "multiple sample adapter".
When blood is collected, the blood collection tube is placed over the cannula, pushing the rubber sheath back, allowing blood flow. After obtaining the correct amount of blood, the blood collection tube is removed from the holder. When the blood collection tube is removed, the rubber sheath extends back over the cannula and stopping blood flow. Blood collection may be continued by connecting additional blood collection tubes, if required.
The device is sterilized using Ethylene Oxide. The device is a prescription-use device intended to be used in hospitals or healthcare facilities.
Here's an analysis of the provided text, focusing on the acceptance criteria and the study proving the device meets them, based on the requested information.
It's important to note that this document is a 510(k) summary for a medical device (blood specimen collection adapter), not an AI/ML software device. Therefore, many of the typical questions for an AI/ML device, such as those related to AI model training, ground truth establishment, expert adjudication, MRMC studies, or standalone algorithm performance, are not applicable to this type of submission. The 'device' here refers to a physical, non-digital product.
Acceptance Criteria and Study Proving Device Performance
1. A table of acceptance criteria and the reported device performance:
The document doesn't provide a direct "acceptance criteria" table with specific quantitative limits for each test. Instead, it describes various performance tests conducted to demonstrate substantial equivalence (SE) to a predicate device. The general acceptance criterion for all tests is "meets design requirements and specifications" and "confirm performance," ultimately aiming to show comparable function and performance to the predicate device, thereby demonstrating substantial equivalence in terms of safety and effectiveness.
Here's an interpretation based on the "Non-Clinical Testing" section and "Technological Characteristics" comparison, outlining the tests performed to demonstrate that the device meets its design requirements and is substantially equivalent:
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Comparative Testing (Functional/Performance Equivalence) | Conducted to verify equivalent function and performance as the predicate device across: |
| - Appearance and Measurement (Dimensions: Subject: 20G, L: 64.1mm, WA: 31.1mm, WB: 23.6mm; Predicate: 20G, L: 64.3mm, WA: 30.5mm, WB: 24.9mm - "Comparable," despite minor differences, supported by non-clinical testing). | |
| - Attachment and Detachment | |
| - Pressure Resistance | |
| - Connection Strength | |
| - Vacuum Tube Insertion and Removal | |
| - Chemical Resistance | |
| Shelf Life/Accelerated Aging | Conducted to ensure functionality, performance, quality, and safety over time (up to 36 months equivalent) for both physical and chemical properties. |
| Physical Testing (Accelerated Aging) | Assessed: Packaging Study/Stability Test (Transportation, Appearance, Seal Strength, Dye Test), Physical Study/Stability Test (Leakage, Tensile Strength, Blood Taking Needle functionality). |
| Chemical Testing (Accelerated Aging) | Assessed: Reducing matter, Metal ions, Titration acidity and alkalinity, Nonvolatile residue, Absorbance (per ISO 1135-3:2016). |
| Sterilization Effectiveness | Demonstrated compliance with ISO 11135:2014 (Ethylene Oxide sterilization) and United States Pharmacopeia <71> for sterility testing. |
| EO Residuals | Complies with ISO 10993-7 for residual gas and chemicals. |
| Particulate Contamination | Complies with ISO 1135-3:2016 for particulate contamination via accelerated aging. |
| Packaging Integrity | Verified through Transportation Test (ISTA 2A), Appearance Test (ISO 11607-1), Seal Strength Test (ISO 11607-2), and Dye Test (ISO 11607-2). |
| Luer Fitting Conformance | Conformed to ISO 80369-7:2016 (small-bore connectors) at 0 and 36 months, with measured dimensions within tolerance. |
| Biocompatibility | Complies with ISO 10993-1, including Cytotoxicity (ISO 10993-5), Sensitization and Irritation (ISO 10993-10), Acute Systemic Toxicity and Material-Mediated Pyrogenicity (ISO 10993-11), and Hemocompatibility (ASTM F756-17, ISO 10993-4). |
| Materials Equivalence | Materials (Hub: Polycarbonate (PC); Cannula: Stainless Steel; Glue: Epoxy; Silicon: Silicon Oil; Sheath: Isoprene Rubber; Holder: Polypropylene (PP)) were compared. While the Predicate uses Polystyrene for the Hub, the Subject device's use of Polycarbonate was supported by "Biocompatibility Testing and Performance Testing was conducted to demonstrate SE." All other materials are the same. |
2. Sample sized used for the test set and the data provenance:
- Sample Size: The document does not explicitly state the numerical sample size (e.g., number of devices) used for each individual test. It lists the types of tests performed. For physical device testing, sample sizes are typically determined by relevant ISO standards or internal quality protocols.
- Data Provenance: The document does not specify the country of origin of the data. Given the "Kawasumi Laboratories, Inc." address in Tokyo, Japan, it is highly likely that testing was performed by or for the manufacturer, potentially in Japan or at contract labs globally.
- Retrospective or Prospective: These are non-clinical, controlled laboratory tests on manufactured devices, so the terms "retrospective" or "prospective" as they apply to clinical studies or real-world data collection are not applicable.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This is a review of a physical medical device. The "ground truth" is established through engineering and laboratory testing against established physical, chemical, and biological standards (e.g., ISO, USP, ASTM). It does not involve human expert interpretation of data in the way an AI/ML device would. Therefore, the concept of "experts establishing ground truth" in this context is not applicable.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not applicable for a physical device undergoing laboratory testing. This concept is relevant for human interpretation tasks, often in AI/ML performance evaluations.
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 blood collection device, not an AI/ML radiology or diagnostic aid. MRMC studies are for evaluating diagnostic accuracy with and without AI assistance.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an algorithm or software device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The "ground truth" for this device's performance is defined by adherence to established international standards (ISO, ASTM, USP) for physical properties, chemical properties, sterility, biocompatibility, and functional performance of medical devices. The predicate device's performance also serves as a benchmark for comparative testing to demonstrate equivalence.
8. The sample size for the training set:
- Not applicable. This is not an AI/ML device, so there is no "training set."
9. How the ground truth for the training set was established:
- Not applicable. As above, there is no "training set" for a physical medical device.

However, I can extract the information provided about the non-clinical performance testing which serves as the "study" for this device, and list the categories of tests that were performed.
1. A table of acceptance criteria and the reported device performance
The document does not provide a table of acceptance criteria with specific numerical targets and corresponding reported device performance values. Instead, it lists categories of non-clinical tests that were performed to demonstrate substantial equivalence. The implication is that the device passed these tests, thereby meeting the implicit acceptance criteria for each test type, which are typically defined by the referenced standards.
| Acceptance Criteria Category (Implicit, based on standards) | Reported Device Performance (Implicit: Passed all tests) |
|---|---|
| Biocompatibility (Cytotoxicity, Skin Sensitization, Intracutaneous Reactivity, Acute Systemic Toxicity, Pyrogen, Hemolysis) | Passed |
| Functional Performance (Visual Inspection, Leakage, Flow Regulator, Volume Marking Accuracy, Blockage, K-Shield Activation, NAC Function, Pull Strength, Sharpness) | Passed |
| Chemical Performance (Reducing Matter, Metal Ions, Titration Acidity/Alkalinity, Non-Volatile Residue, Absorbance) | Passed |
| Sterilization/Sterility (Residual Gas, Material Mediated Pyrogen, Particulate, Sterilization Validation, Packaging) | Passed |
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 the individual non-clinical performance tests nor the data provenance. These tests are typically conducted in a laboratory setting by the manufacturer or a contract research organization.
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)
Not applicable. The device is a traditional physical medical device (blood drawing kit), not an AI/ML device that requires expert-established ground truth for a test set.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This is not an AI/ML device for which adjudication methods for expert disagreement would be relevant.
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 traditional medical device; MRMC studies relate to AI/ML image interpretation or diagnostic tools.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a traditional medical device; standalone algorithm performance is relevant for AI/ML devices.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For a blood drawing kit, "ground truth" would relate to meeting physical, chemical, and biological performance specifications outlined in recognized standards. This is demonstrated through objective laboratory testing rather than expert consensus on diagnostic outcomes. The "ground truth" is adherence to established engineering and medical device standards.
8. The sample size for the training set
Not applicable. This is a traditional medical device, not an AI/ML device that requires a training set.
9. How the ground truth for the training set was established
Not applicable. This is a traditional medical device, not an AI/ML device.

2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size: The document does not explicitly state the sample size used for each specific test. For non-clinical tests like material and performance evaluations, typically multiple samples are subjected to each test.
- Data Provenance: The tests were performed internally by Kawasumi Laboratories, or according to international standards (ISO, ASTM, ISTA, EN). The country of origin for the studies is implied to be Japan, where Kawasumi Laboratories, Inc. is based, or potentially other locations if testing was outsourced. The data is retrospective in the sense that it was generated prior to the 510(k) submission, but it represents prospective testing conducted to evaluate the device's performance.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications:
This section is largely not applicable as the studies described are non-clinical engineering and materials tests, not studies involving human subjects or expert assessment of clinical images/diagnoses. The "ground truth" for these tests is defined by the specific parameters and requirements of the international standards (e.g., ISO, ASTM) and Kawasumi's internal validation protocols. No human experts were involved in establishing "ground truth" in the way understood for medical diagnostic devices.
4. Adjudication Method for the Test Set:
This section is not applicable as the tests are objective, pass/fail engineering and material science evaluations against defined standards. There is no subjective interpretation or need for adjudication.
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:
This is not applicable. The device is an infusion set with high-pressure tubing, not an AI-powered diagnostic or assistive technology. Therefore, no MRMC study was conducted, and the concept of "human readers improve with AI" does not apply.
6. If a Standalone (i.e. algorithm only, without human-in-the-loop performance) was done:
This is not applicable. The device is a physical medical device (infusion set), not an algorithm or software. No standalone algorithm performance study was done.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.):
The "ground truth" for the non-clinical tests is based on:
- Defined Standards and Specifications: The reference to ISO, ASTM, ISTA, and EN standards indicates that the ground truth is the performance criteria established within these internationally recognized specifications.
- Engineering Specifications: Kawasumi's internal tests (flow rate, pinch clamp pressure) would have had pre-defined, measurable specifications as their ground truth.
- Essentially, the ground truth is quantifiable, objective measurements against established benchmarks for material properties, pressure resistance, and functionality.
8. The Sample Size for the Training Set:
This is not applicable. As a physical medical device, there is no "training set" in the context of machine learning or AI. The design and manufacturing processes are validated against established engineering principles and standards.
9. How the Ground Truth for the Training Set Was Established:
This is not applicable for the reasons stated above. The "ground truth" for the device's design and manufacturing is established through adherence to recognized engineering standards, material science principles, and quality control processes, not through a "training set" with established ground truth in the AI sense.

| Substantially equivalent to predicate devices in function | Achieves the same results as predicate device (Becton Dickinson Vacutainer Brand Safety-Lok Blood Collection Set) |
2. Sample Size Used for the Test Set and Data Provenance
- Test Set Sample Size: Not specified. The document mentions "a successful simulated use study" but does not provide details on the number of units or uses tested.
- Data Provenance: The study was conducted by Kawasumi Laboratories, Inc., located in Tokyo, Japan. The study is described as a "simulated use study," implying it was conducted in a controlled environment, likely within their facility. It is a prospective study as it was conducted specifically to demonstrate the device's performance for this 510(k) submission.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
This information is not provided in the given text. The study is described as a "simulated use study" but does not mention the involvement of experts in establishing ground truth or evaluating the results. The determination of "success" likely relied on internal assessment criteria by Kawasumi Laboratories.
4. Adjudication Method for the Test Set
This information is not provided in the given text. There is no mention of independent reviewers or an adjudication process for the "simulated use study."
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is typically associated with diagnostic imaging devices or algorithms where human readers interpret medical images with or without AI assistance. The device in question is a medical device designed to prevent needlestick injuries, and such a study would not be applicable.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done
This question is not applicable to the device described. The device is a physical product (winged needle set with an antineedle stick protector), not an algorithm or software. Its performance inherently involves human interaction during its use to activate the protector.
7. The Type of Ground Truth Used
The "ground truth" for this device's performance would likely be a direct observation of whether the needle tip was successfully shielded or retracted after simulated use, thereby preventing accidental needlestick. The text states: "In both devices, the needle tip is protected inside the device after use." This implies the ground truth for success was the successful physical enclosure of the needle tip.
8. The Sample Size for the Training Set
