Lmed JAY-5BW Oxygen Concentrator Analysis Report

Device Identification

The main product shown in the images is an electrical device that provides medical respiratory support. Upon examining the visual details (flow meter, humidifier bottle, filter inlets), it has been determined that this device is an Oxygen Concentrator, which takes ambient air, separates oxygen, and provides high-purity oxygen to the patient.

Brand and Model

On the front face of the device, the Lmed (Lmed Healthcare) brand is clearly visible, along with a circular logo with green dots. On the label of the product’s original cardboard box, the code JAY-5BW is written next to the Model designation. Furthermore, the manufacturer information Longfian Scitech Co., Ltd. is legible on the label. In light of this data, the product’s brand has been confirmed as Lmed, and its model as JAY-5BW.

Originality

The factory labels, barcodes, importer company information (Lmed Tıbbi Sağlık Ürünleri Tic. Ltd. Şti.), and manufacturer information on the product’s box are in complete harmony with the brand print on the front face of the device. Considering the “CE 0197” certificate number, the user manual, and the quality of the packaging, the product is assessed to be an original medical device.

Areas of Use

This device is designed for home oxygen therapy for patients experiencing respiratory failure such as COPD, asthma, pulmonary fibrosis, or those with decreased blood oxygen saturation. It filters ambient air to produce oxygen with 93% (+/- 3%) purity and delivers it to the patient via a cannula. It is suitable for hospital and home care processes.

Quantity Information

The content displayed in the visuals is as follows:

• 1 unit Oxygen Concentrator Main Unit
• 1 unit Humidifier Water Bottle (May be attached to the device or spare in the box; a similar type of black-capped bottle is visible in the images)
• 1 unit User Manual and Document Set
• 1 pack Oxygen Cannula/Tubing (Green-tipped)
• 1 unit Spare Air Filter (Green sponge type)
• 1 unit Spare Carbon/Black Filter

General Condition and Physical Condition

The device is shown with its original box and foam protections (styrofoam). No yellowing, dirt accumulation, or signs of use are noticeable on the device’s casing. Its outer plastic body appears clean, white, and shiny. The product gives the impression of being newly unboxed or never used (New/Open Box). Its mechanical and cosmetic condition is top-tier.

Physical Deformation

No cracks, breaks, dents, or deep scratches have been detected on the product’s plastic casing. The air grilles are intact. No significant wear is discernible on the wheels or base in the visual. The labels are complete and legible, with no lifting or peeling at the corners.

Mechanical and Electronic Components

From the visuals, it is understood that the mechanical integrity of the device is preserved:

• Flowmeter: The transparent tube (0-5 L/min scale) on the front of the device is clean and undamaged. The adjustment knob is in place.
• Filter and Grilles: The air intake grille on the side cover is clean; no dust accumulation is observed inside it.
• Casing Integrity: The front and side panels are perfectly aligned; there are no gaps.

Accessories

The device is seen inside its styrofoam-protected box, along with its necessary accessories:

• An oxygen cannula with green connection tips is present in a clear plastic bag. The bag appears unopened.
• The humidifier bottle has a black cap and a clear body; its connection adapter is attached. It is clean and free of limescale.
• Spare filters (green and black sponges) are available inside the user manual bag.

Label Information

The label on the product’s box contains the following technical data and identification information:

• Brand/Model: JAY-5BW
• Manufacturing Date (MFD): 2023-03-26 (March 26, 2023)
• Lot Number: 23J0198
• Serial Number: MZJ5S522911
• Electrical Input: 230V, 50Hz, 540VA
• Weight: Net 22 Kg / Gross 24 Kg
• Expiration Date (EXP): 5 YEARS (Typically a 5-year period indicated for device lifespan or accessory shelf life)
• Box Dimensions: 430 x 380 x 690 mm

Technical Specifications and Screen Analysis

Although there is an electronic screen (LCD) in the visual, the data on it cannot be read as it is turned off. However, it is understood from the mechanical flow meter that the device’s capacity is 5 Liters/minute (Scale is between 0 and 5). The warning texts on the front of the device contain the following information:

• The inlet air filter should be cleaned every 100 hours of use.
• The secondary filter should be cleaned every 300 hours of use.
• Oxygen purity is 93% ±3% at nominal flow.
• Warning not to smoke or approach with fire.
• Warning not to use oil or grease.

Manufacturing Year and Usage Period

The phrase “MFD: 2023-03-26” is clearly legible on the box label. This indicates that the device was manufactured in March 2023. The device’s physical cleanliness, its accessories being in plastic bags, and its storage in the box suggest very little usage or that the device has never been used (it may have been stored in stock). However, since the digital hour counter (LCD screen) is off, the exact operating hours cannot be determined from the visual.

Potential Malfunction Risk and Conclusion

In the visuals, no negative findings such as cracks, burn marks, cable breaks, liquid contact, or rust, which would affect the device’s functionality, have been observed. The relatively recent manufacturing date of the device (2023) and its complete/protected accessories instill confidence. Based on its current appearance, it can be stated that it is a medical device in high condition, ready for immediate use.
