Alltimes 7F-5B Oxygen Concentrator Analysis Report

General Assessment

The device shown in the visuals is an oxygen concentrator that provides concentrated oxygen obtained from ambient air for users requiring respiratory support. The general physical condition of the device is quite high; no signs of wear, dirt, or damage have been observed on it. The presence of the protective packaging film still on the top surface of the device suggests that the product has either never been used or has been used very little. This indicates that the device is in a near-new condition.

Brand and Model Identification

In the detailed examination, the Alltimes brand logo and name are clearly visible on the front panel and the rear label of the device. Similarly, the model information, 7F-5B, is clearly stated on both the front panel and the rear label containing technical specifications. This information has been confirmed with 100% accuracy through the visuals.

Physical Condition and Deformation Analysis

The outer casing of the device is in perfect condition according to visual inspections. No deformation such as scratches, cracks, dents, or color fading has been detected on it. The white plastic components are clean and spotless. All surfaces, including the control panel, screen, and buttons, appear to be very well-maintained.

Mechanical and Electronic Components

The device’s wheels, mechanical components providing mobility, and parts such as the flow meter adjustment knob appear to be functional and robust. No signs of crushing, wear, or damage have been found on the electrical cable and plug. Although the device is shown in the off state in the visuals, so its screen operation could not be tested, there is no physical damage (cracks, scratches, etc.) on the screen itself. Fixed texts on the screen such as “COUNTS (Hours)” and “TIMING (Minutes)” indicate that the device records total operating hours and allows for timed usage.

Accessories and Equipment

The equipment visible with the device in the visuals is listed below:

• Main oxygen concentrator unit
• Water reservoir (humidifier) attached to the device
• Power cable, integrated into the device and gathered at the back

No accessories for oxygen delivery, such as a nasal cannula or oxygen mask, are visible in the box contents or anywhere in the visuals.

Technical Label Information

The technical label on the back of the device has been carefully examined, and the following information has been obtained. This information includes the device’s technical specifications and production details:

• Brand: Alltimes
• Model: 7F-5B Oxygen Concentrator
• Serial Number: SN 230228074
• Production Date: 04/08/2023
• Power Supply: ~220V +/-10%, 50Hz
• Input Power: 400VA
• Oxygen Concentration Range: 95.5% – 87%

Important Notes and Observations

Some important points observed based on visual analysis are as follows:

• Since the device is in the off position, the total operating hours (COUNTS) information on the digital display cannot be read.
• The presence of the protective film on the top panel is strong evidence that the product has been used very little or not at all.
• No documents such as a user manual, warranty certificate, or invoice are visible in the visuals.

Potential Malfunction Risk Assessment

Based on the assessment made from the available visuals, no situation indicating a potential malfunction risk has been observed in the device. The product’s excellent overall condition, absence of physical damage, and clean appearance indicate that the device has been well-maintained. The lack of wear, rust, or impact marks on the cables or casing suggests that the device, in its current state, will offer safe usage.
