Intended Use

The Portable Oxygen Concentrator P2-TOC is intended to provide supplemental low flow oxygen.

The device is not intended for life support, nor does it provide any patient monitoring capabilities. This device is for adults only.

Device Description

The Portable Oxygen Concentrator P2-TOC is a device that uses the principle of molecular sieve pressure swing adsorption to increase oxygen concentration by adsorption of nitrogen and other gas components. The device needs to be used with a nasal oxygen cannula, which can provide oxygen supplementation to the user.

The Portable Oxygen Concentrator P2-TOC has two oxygen supply modes, namely continuous oxygen supply mode and pulse oxygen supply mode. Hereinafter referred to as "continuous mode" and "pulse mode" .

In the continuous mode, the Portable Oxygen Concentrator P2-TOC can continuously deliver oxygen at a fixed flow rate. In the pulse mode, the Portable Oxygen Concentrator P2-TOC is able to deliver oxygen only when the user inhales by detecting the human respiratory rate.

AI/ML Overview

The provided text describes a 510(k) premarket notification for a Portable Oxygen Concentrator (P2-TOC). It details the device's characteristics and compares it to predicate devices to demonstrate substantial equivalence. However, the document does not contain information related to an AI/ML-enabled device or a study involving human experts, ground truth establishment, or comparative effectiveness with AI assistance.

Therefore, I cannot fulfill most of the requested points as the provided document is for a physical medical device (portable oxygen concentrator) and not an AI/ML diagnostic or therapeutic device.

The document primarily focuses on:

  • Device Description and Indications for Use: What the portable oxygen concentrator does.
  • Principle of Operation: How it separates oxygen from air.
  • Comparison with Predicate Devices: Demonstrating similarity in function and safety to already-marketed oxygen concentrators.
  • Non-Clinical Tests Performed: This section lists various engineering and safety standards (electrical safety, EMC, software verification, biocompatibility) that the device complies with. These are standard tests for medical devices to ensure quality and safety, not AI model performance.
  • Absence of Clinical Accuracy Testing: Explicitly states "There was no clinical testing performed." This is common for 510(k) submissions where substantial equivalence can be demonstrated through non-clinical means.

Here's what I can extract from the provided text regarding acceptance criteria and performance, focusing on what is relevant for a physical medical device:

The "acceptance criteria" for a physical device like a Portable Oxygen Concentrator are typically defined by compliance with recognized consensus standards and performance specifications. The "study that proves the device meets the acceptance criteria" refers to the non-clinical testing performed to show compliance with these standards and performance specifications.

1. Table of Acceptance Criteria and Reported Device Performance (Based on "Comparison with predicate device" and "Non-Clinical Tests Performed"):

Regarding the points specific to AI/ML devices, I must state that the document does not provide the requested information for the following reasons:

2. Sample size used for the test set and the data provenance: Not applicable. This document describes testing for a physical device's compliance with engineering standards, not an AI model trained on data. There is no concept of a "test set" from a data perspective. The "testing" refers to bench testing of the physical hardware and embedded software. Data provenance would not be a relevant concept as it pertains to clinical data for AI model training/testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No clinical test set or ground truth established by experts is mentioned. The ground truth for device performance is based on physical measurements against established engineering and medical device standards.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No clinical test set requiring expert 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: Not applicable. This is a physical oxygen concentrator, not an AI-assisted diagnostic or therapeutic device that would involve human readers.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This refers to a physical device, not a standalone AI algorithm. While it has embedded software, its "performance" is measured by its physical output (oxygen concentration, flow rate) and adherence to safety standards, not by an algorithm's classification or detection accuracy.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not applicable. The "ground truth" for this device's performance is determined by direct measurement of physical parameters (e.g., oxygen purity, flow volume, noise levels) and compliance with specified engineering and safety standards, as detailed in the "Non-Clinical Tests Performed" section.

8. The sample size for the training set: Not applicable. This is for an AI/ML model, not a physical medical device. The device itself is manufactured; it doesn't "learn" from a training set in the AI sense.

9. How the ground truth for the training set was established: Not applicable. See point 8.

In summary, the provided document is a regulatory submission for a physical Portable Oxygen Concentrator, and therefore, the information requested, which pertains to AI/ML device performance and validation studies, is not present. The "acceptance criteria" and "study that proves the device meets the acceptance criteria" for this device are based on demonstrating compliance with a comprehensive set of recognized consensus engineering and safety standards through non-clinical bench testing.

V. Device description and Indications for Use

Device description: The Portable Oxygen Concentrator P2-TOC is a device that uses the principle of molecular sieve pressure swing adsorption to increase oxygen concentration by adsorption of nitrogen and other gas components. The device needs to be used with a nasal oxygen cannula, which can provide oxygen supplementation to the user.

The Portable Oxygen Concentrator P2-TOC has two oxygen supply modes, namely continuous oxygen supply mode and pulse oxygen supply mode. Hereinafter referred to as "continuous mode" and "pulse mode" .

In the continuous mode, the Portable Oxygen Concentrator P2-TOC can continuously deliver oxygen at a fixed flow rate. In the pulse mode, the Portable Oxygen Concentrator P2-TOC is able to deliver oxygen only when the user inhales by detecting the human respiratory rate.

Indications for Use: The Portable Oxygen Concentrator P2-TOC is intended to provide supplemental low flow oxygen.

The device is not intended for life support, nor does it provide any patient monitoring capabilities. This device is for adult only.

VI. Principle of operation

The Portable Oxygen Concentrator P2-TOC works by getting use of the molecular sieves character that the internal pressure of a sealed container containing of molecular sieve will increase when injecting air into it. At this time, the molecular sieve will absorb a lot of nitrogen in the air with the increasing of ambient pressure, while the oxygen in the air is still existed in gaseous form, then the oxygen are collected in the Air receiver. When the nitrogen absorption process in the container reaches a certain level, then exhaust of the vacuum container and nitrogen will be released from molecular sieve with the ambient pressure decreases. It will detect when the user begins to take a breath and then delivers a pulsed volume of oxygen during the inhalation period. The volume of the oxygen pulse is dependent on the setting value.

Note:

ID3,ID4:

The Indication for Use description of P2-TOC is similar to the description of Model 4000. We added a "low flow" reference to the intended use to prevent user misunderstanding and reduce risk.

The Environment of Use of P2-TOC is basically the same as the description of Model 4000.Therefore the difference does not raise new questions of safety and effectiveness.

ID8:

The dimensions of Model 1000and Model 4000 compared and theP2-TOC devices differ in dimensions due to their different designs. The risk is mitigated by tests tested according to ISO 80601-2-69: 2020,EC60601-1and ISO 80601-2-67: 2020, therefore the difference does not raise new questions of safety and effectiveness.

ID9, ID14, ID20 and ID21:

Although the weight, power supply, operating and shipping storage environment conditions of P2-TOC is different from the predicate devices (Model 1000 and Model 4000), but the subject device has passed the differences don't raise new questions of safety and effectiveness.

ID10:

The oxygen concentration of predicate devices Model 4000 both are 90% +- 3% for all 110w settings and of subject device P2-TOC is 90%-3% at all settings. The risk is mitigated by tests tested according to ISO 80601-2-67: 2020, therefore the difference does not raise new questions of safety and effectiveness.

ID11:

In continuous mode, both P2-TOC and predicate devices (Model 4000) have same ranges of 1.0-3.0L/min.

In pulse mode, the flow range of the Model1000 is 16-96 mL. The breathing rate is 6-25 beats per minute, so the maximum flow rate in pulse mode is 2400ml (25*96mL).

In pulse mode, the flow range of the Model4000 is 16-192mL when the breathing rate is 15 times per minute, so the maximum flow rate in pulse mode is 2880mL (15*192mL).
