A&J 5L POCA series Oxygen Concentrator is intended for use as an oxygen concentrator to provide supplemental low flow oxygen therapy at home, in nursing homes, at patient care facilities. A&J 5L POCA series is available by prescription only under the supervision of a physician.
A&J 5L POCA series Oxygen concentrator is AC power electrically operated. The unit separates oxygen from room air (ambient air) which allows high-purity supplemental oxygen to be delivered through the oxygen outlet, although the concentrator filters the oxygen in a room, it will not affect the normal amount of oxygen in your room. Air is drawn into the device with a compressor and exposed to molecular sieve adsorbent that selectively retains nitrogen and other components until they are released when the pressure is vented to the atmosphere. This cycle is controlled by a motorized value and protected from over pressurization by the compressor's pressure relief value.
Oxygen provided by the A&J 5L POCA series Oxygen concentrator is delivered to the user by means of standard oxygen supply tubing and a standard nasal cannula or mask. A standard bubble humidifier may be used, if physician has prescribed an oxygen humidifier as part of therapy.
The front panel of the A&J 5L POCA series Oxygen concentrator contains the controls and indicators. These include the status lights (included power light, normal oxygen light, fow oxygen light and service required light), standard power switch, flow meter knob, a circuit breaker which could reset the device after electrical overload shutdown, an oxygen outlet which oxygen is dispersed through, a monitor display which indicates the condition of system status (included pressure status, oxygen purity status and electric hour meter, etc.). The user could operate the device conveniently according to the instructions.

The provided 510(k) summary for the A&J-POCA01 Oxygen Concentrator describes a medical device seeking substantial equivalence to a predicate device. This type of submission relies on demonstrating that the new device is as safe and effective as a legally marketed predicate device, rather than requiring a detailed clinical study with acceptance criteria and ground truth validation as would be typical for novel or higher-risk devices.
Therefore, the document does not contain information on:
- Acceptance criteria in the manner of performance metrics (e.g., sensitivity, specificity) for diagnosing or detecting a condition.
- A "study that proves the device meets the acceptance criteria" in a clinical sense with a test set, ground truth, and expert evaluation.
- Sample sizes for test sets or training sets for an AI/algorithm.
- Number/qualifications of experts, adjudication methods, MRMC studies, or standalone algorithm performance studies.
- Type of ground truth used (e.g., pathology, outcomes data).
Instead, the submission focuses on bench performance testing to demonstrate functional equivalence and safety.
Here's a summary of the information available, framed in response to your request, but highlighting the type of study conducted:
