Alltimes Oxygen Concentrator Analysis Report

Overview and Product Description

The product shown in the visuals is an oxygen concentrator understood to be for medical use. The device has a mechanism that produces oxygen using ambient air and provides it to users who need respiratory support. A total of one main device and its attached accessories have been examined.

Brand and Model Identification

On the lower part of the device’s front surface, the Alltimes brand is clearly legible within a blue oval label. Although there are some writings below this brand, believed to be model information, model identification cannot be made due to insufficient clarity in the visual.

Physical Condition and Deformation Analysis

The device generally has a clean and well-preserved appearance, and it is understood to have been used. No significant discoloration, yellowing, or large stains were observed on its white plastic casing. To the extent permitted by the visuals, no noticeable deep scratches, cracks, dents, or broken parts were detected on the device’s surface.

Mechanical and Electronic Component Evaluation

Mechanical parts appear problem-free in visual analysis. The transparent cover protecting the humidifier reservoir, the white rotary knob for flow adjustment, and the oxygen outlet port are physically intact.

There is no break or crack in the glass of the digital screen located on the device’s front panel. All buttons and the power switch on the control panel are in place and show no signs of physical damage.

Control Panel and Screen Examination

A user-friendly control panel is located on the upper front part of the device. The features of this panel are as follows:

• Digital Display: The panel features a display showing COUNTS (hours) for the device’s total operating time and TIMING (minutes) for timed usage. No data is readable on the screen in the photos because the device is not operating.
• Timer Settings: The TIMING function can be adjusted between 1 and 99 minutes (1-99min) using the + and – buttons.
• Power Switch: There is a black POWER switch used to turn the device on and off.
• Other Controls: The panel also includes up/down arrow buttons, understood to be for settings and functions, and an I/O button.

Accessories and Connection Points

The following accessories have been identified with the device in the visuals:

• Humidifier Reservoir: A water/humidifier bottle with a black cap is attached in the transparent compartment at the front of the device. There is some liquid inside the bottle.
• Flow Meter: Next to the humidifier reservoir, there is a flow meter showing the amount of oxygen delivered per minute (L/min). Its scale indicates it can measure up to 5 L/min.
• Oxygen Output Connector: A white plastic adapter, used for attaching the oxygen cannula, is connected to the outlet port labeled OXYGEN OUTLET.

No other accessories such as an oxygen mask, nasal cannula, spare filter, or user manual are present in the visuals.

Label Information

On the top surface of the device, there is a large label containing usage and safety warnings. However, the texts on this label are not legible. Therefore, technical details such as Serial Number, REF Code, or Lot Number could not be identified.

Potential Risk Assessment

Based solely on visual data, no situation indicating a serious potential risk of malfunction has been observed on the device. There are no signs of crushed cables, severe damage to the casing, or rust. The device’s overall physical condition suggests that it has been used properly and maintained.
