All Times 7F-5B Oxygen Concentrator Analysis Report

Device Identification and Information

The product in the image is a home-use oxygen concentrator, a medical device that provides high-concentration oxygen by separating it from ambient air for patients requiring respiratory support. The device is designed for vertical positioning, is wheeled (due to its casing), and suitable for stationary use.

• Brand: On the front face of the device, below the humidifier reservoir, the inscription All Times is clearly visible within a blue oval logo.
• Model: At the very bottom of the front panel, directly beneath the logo, the model number 7F-5B is clearly written in black font.
• Product Type: Medical Oxygen Concentrator.

Areas of Use

This device is used to provide continuous oxygen support to patients with chronic respiratory diseases such as COPD, asthma, pulmonary fibrosis, or in cases of low blood oxygen levels (hypoxemia). It is suitable for long-term oxygen therapy in home care services, nursing homes, or clinical settings. It operates on electricity and delivers oxygen via a cannula connected to the patient’s nose.

General Condition and Status

The device appears clean and in solid condition overall. No yellowing or significant discoloration has been observed on its outer casing; it retains its white color. It appears to be second-hand and in active use (due to the presence of water in the humidifier reservoir), but it does not present a worn-out or neglected appearance.

Mechanical and Physical Examination

Examinations conducted on the device’s outer casing and visible mechanical parts are as follows:

• Outer Casing: The integrity of the plastic casing is preserved, and no cracks, breaks, or dents have been detected on visible surfaces.
• Flowmeter: The transparent tube-shaped flowmeter located on the right side of the device is intact. Its adjustment knob (regulator) is present. The black lines and numbers indicating flow levels are legible.
• Humidifier Reservoir (Water Bottle): The transparent humidifier bottle located in the central part of the device is in place. Its cap and connection points appear secure. A black tape/strip, thought to have been applied later, is present on the bottle. The bottle is seen to be half-filled with water.
• Outlet Port: The metal or hard plastic oxygen outlet tip, labeled “OXYGEN OUTLET,” located on the left side, is intact and has a tube attached to it.
• Power Switch: The black “I/O” power switch located on the top panel is intact and in place.

Electronic Components and Screen Analysis

The device’s upper control panel features a digital LCD screen. Although the screen appears off (or unlit in the photograph), it physically shows no breaks or cracks. Next to the screen are control buttons and indicator lights (POWER, etc.) with the inscriptions “COUNTS (HOURS)” and “TIMING (MINUTES)”.

Accessories and Connections

Accessories attached to the device are visible in the image:

• Oxygen Tubing: A standard transparent-green oxygen tube/cannula is seen attached to the device’s oxygen outlet. No visible breaks or kinks are present in the tubing.
• Humidifier Bottle: The water container is present, resting in its integrated slot on the device.

Quantity Information

The image shows 1 (one) All Times brand oxygen concentrator and 1 (one) tube attached to the device.

Existing Faults and Potential Risk Analysis

During the visual inspection, no broken parts, disconnected cables, or error-indicating warning lights that would impede the device’s operation were detected. However, since the duration of the water’s presence in the humidifier container cannot be determined from the image, it should be noted that the water needs to be changed regularly for hygiene purposes. Mechanically, the device appears ready for use and problem-free.

Conclusion and Evaluation

The examined All Times 7F-5B model oxygen concentrator is a medical device in good physical condition, complete (including humidifier bottle and tubing), and with a clean casing. The presence of water in the humidifier bottle indicates that the device has been recently used or is currently in use. No visible damage or deformation is present.
