AI/ML Overview

The provided document is a 510(k) summary for the Caremed Reusable Blood Pressure Cuff and Caremed Disposable Blood Pressure Cuff. It focuses on demonstrating substantial equivalence to predicate devices rather than proving a device meets specific acceptance criteria through a clinical study for a new medical AI or advanced diagnostic device. Therefore, much of the requested information (e.g., sample size for test sets and training sets, number of experts, adjudication methods, MRMC studies, ground truth types) is not directly applicable or available in this type of submission for a blood pressure cuff.

However, I can extract information related to the performance data provided within the context of a 510(k) submission for this device.

1. Table of Acceptance Criteria and Reported Device Performance

For a blood pressure cuff, the "acceptance criteria" and "reported device performance" are primarily related to safety, material biocompatibility, and functional performance (e.g., pressure range, leakage, and compliance with recognized standards).

Acceptance Criteria / StandardReported Device PerformanceComments
Biocompatibility - Cytotoxicity (per ISO 10993-5)No potential cytotoxicityPass
Biocompatibility - Sensitization (per ISO 10993-10)No sensitization observed (test sample score 0)Pass
Biocompatibility - Irritation (per ISO 10993-10)Negligible (no observed primary irritation, test sample score 0)Pass
Non-Invasive Sphygmomanometers Requirements (per ISO 81060-1:2007)Device met all design specifications and complied with the standardPass
Maximum Leakage< 4mm Hg/ min.Same as predicate, presumed compliant with relevant standards.
Pressure Range0-300 mmHgSame as predicate, presumed compliant with relevant standards.
Max. Pressure (for Disposable Cuff)400 mmHgSame as predicate, presumed compliant with relevant standards.

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

This information is typically not provided in a 510(k) summary for a blood pressure cuff. The "test set" here refers to samples of the device materials tested for biocompatibility and the device itself for functional performance.

  • Sample Size for Test Set: Not specified in the document. Standard practice would involve testing a representative number of samples to demonstrate compliance with standards for biocompatibility and functional performance.
  • Data Provenance: Not explicitly stated as country of origin but likely conducted by testing laboratories in China, given the manufacturer's location. The studies are "non-clinical" and likely retrospective in that they characterize the manufactured product.

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

Not applicable in this context. The "ground truth" for a blood pressure cuff's performance is typically established by objective physical and chemical testing against established international standards (e.g., ISO for biocompatibility and sphygmomanometers), not by expert consensus or readings.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods like 2+1 or 3+1 are used for evaluating human reader performance in diagnostic studies, which is not relevant for a blood pressure cuff's mechanical and material performance 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

Not applicable. This is a blood pressure cuff, not an AI-powered diagnostic device. No human-in-the-loop performance or MRMC study was conducted or is relevant.

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

Not applicable. This is not an algorithm or AI device.

7. The Type of Ground Truth Used

The "ground truth" for the performance claims of these blood pressure cuffs is based on objective measurement against established international standards (e.g., ISO 81060-1 for non-invasive sphygmomanometers, ISO 10993 for biocompatibility) and direct physical/chemical testing.

8. The Sample Size for the Training Set

Not applicable. This is not an AI device that requires a training set.

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

Not applicable.

Justification of differences:

Justifications for differences between Caremed Blood Pressure Cuff and the predicate device are shown as below:

Different (1): We claim the applicable population in more detail. Neonatal, infant and child are subsets of the pediatric patient population. Thus, this descriptive difference does not raise any safety or effectiveness issue.

Different (2): The limb circumference of subject device and predicate device is same. The subject device is less than predicate device with Large Adult Long. This difference limits use within the subject device and does not raise any safety or effectiveness issue.

Different (3): We claim the applicable population in more detail. Neonatal, infant and child are subsets of the pediatric patient population. Thus, this descriptive difference does not raise any safety or effectiveness

{8}------------------------------------------------

issue.

Different (4): The limb circumference of subject device and predicate device is same. The subject device is less than predicate device with Thigh. This difference limits use within the subject device and does not raise any safety or effectiveness issue.

Conclusion:

The proposed devices share the same indications for use, device operation, overall technical and functional capabilities, meet the same standards and requirements and therefore, are substantially equivalent to the predicate device(s).

8. Performance Data

The following performance data were provided in support of the substantial equivalence determination.

Biocompatibility testing

The biocompatibility evaluation for the Caremed Blood Pressure Cuffs was conducted in accordance with the FDA Biocompatibility guidance, 2016 (Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process") and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The battery of testing included the following tests:

  • Cytotoxicity .
  • Sensitization .
  • Irritation .

The Caremed Blood Pressure Cuffs are considered surface contacting for a duration of exceed 24 hours but not 30 days.

Non-clinical data

Non-clinical tests were conducted to verify that the proposed device met all design specifications as was Substantially Equivalent (SE) to the predicate device. The test results demonstrated that the proposed device complies with the following standards:

  • . ISO 81060-1. Non-Invasive Sphygmomanometers - Part 1: Requirements and Test Methods for Non-Automated Measurement Type, First Edition 2007.
  • . ISO 10993-5: 2009 Biological Evaluation of Medical Devices - Part 5: Tests for In Vitro Cytotoxicity.
  • . ISO 10993-10: 2010 Biological Evaluation of Medical Devices - Part 10: Tests for Irritation and Skin Sensitization

The test was selected to show substantial equivalence between the subject device and the predicate.

{9}------------------------------------------------

K182433 Page 7 of 7

Conclusion 9.

It has been shown in this 510(k) submission that the difference between the proposed devices and the predicate devices do not raise any questions regarding safety and effectiveness. Performance testing and compliance with voluntary standards demonstrate that the proposed are substantially equivalent to the relevant aspects of the predicate devices in terms of design, components, materials, principals of operation, biocompatibility, performance characteristics, and intended use.
