Lmed JAY-5AW Oxygen Concentrator Analysis Report

Device Identification and Basic Information

The product shown in the images is an oxygen concentrator designed for conditions requiring respiratory support. Based on the logo on the device’s front panel and the manufacturer’s label on its rear panel, the brand has been identified as Lmed, and the model as JAY-5AW. Upon examining the device’s casing structure, label print quality, CE certification mark, and screen interface, the product is assessed to be an original medical device.

Physical Condition and State

The device’s outer casing is made of light blue hard plastic. No cracks, breaks, deep scratches, or dents were observed during the inspection of the casing. There is no color fading or significant dirt accumulation. Overall, the device is clean, its integrity is preserved, and it is in good condition.

Mechanical and Electronic Components

The device’s mechanical and electronic components are visually in sound condition. The identified details are listed below:

• There are four wheels at the base of the device to facilitate transport, and no physical damage is observed on the wheels.
• On the right side panel, there is a grilled section that provides air intake for the device, and a black filter sponge is located inside this section.
• On the left side of the front panel, there is a transparent flow meter (flowmeter) with an indicator ball inside, used to adjust the oxygen flow rate.
• The device’s power cable is connected, and it is understood that the electronic components are operational from the illuminated screen and the lit LED light on the control panel.

Screen and Usage Data

The device’s front panel features a blue backlit LCD screen and a membrane keypad. There is no pixel loss or cracks on the screen. The data read from the screen are as follows:

• S.Times: 0000509 (Indicates the number of times the device has been started)
• O.P. MPa: 0.164 (Operating pressure value)
• O.Time: 0000 00 (Current usage time)
• Acc.Time: 0003070 (Cumulative operating time, indicating the device has been used for a total of 3070 hours)

On the right side of the screen, there are up arrow, down arrow, and power (I/O) buttons. At the bottom of the screen, there are six LED indicators for status notifications (P.O., P.F., L.P., H.P.(T), L.O2, H.O2). In the images, the P.O. (Power On) indicator was observed to be lit in green.

Label Information and Warnings

On the rear panel of the device, there is a white manufacturer’s label containing technical data and a red warning label at the top. The information on the labels is as follows:

• Device Description: Medical Oxygen Concentrator
• Model: JAY-5AW
• Input Values: 230V, 50Hz
• Power Consumption: 480VA
• Certification: CE mark is present.
• Warning Label: It is stated in English that smoking is prohibited during oxygen use; and the device should not be used in environments with open flames, sparks, or heat sources.

Accessories and Equipment

A total of 3 pieces of equipment/accessories, integrated into the device and ready for use, have been identified in the images:

• Humidifier Water Bottle: 1 unit. Secured to the slot on the front left side of the device with a black elastic band. No signs of breakage or leakage.
• Connection Tubing: 1 unit. Made of transparent silicone/plastic, it is connected between the device’s oxygen outlet port and the top cap of the humidifier water bottle.
• Power Cable: 1 unit. A black standard power cable is plugged into the socket at the rear bottom of the device. No crushing or wear is observed on the cable.

Area of Use and Purpose

This device is a home-use mechanical respiratory support device that filters ambient air to produce medical-grade concentrated oxygen. It is used in home care settings and clinical environments to provide continuous or intermittent oxygen support to patients in the treatment of various respiratory diseases such as COPD, sleep apnea, or conditions with low blood oxygen levels.

Potential Malfunction Risk and General Assessment

During the inspection based on the images, no error codes, broken parts, missing equipment, or physical deformation indicating a malfunction of the device were detected. The casing integrity is complete, and there is no wear on the cables or socket inputs that would pose a danger. The functioning of the device’s screen and the illumination of the power light indicate that its basic electronic functions are active. The overall condition of the device is good, and no significant potential malfunction risk has been observed based on the visual data.
