All times 7F-5B Oxygen Concentrator Analysis Report

Product Description and Intended Use

The device shown in the visuals is an oxygen concentrator of model 7F-5B from the All times brand. Such devices are used to provide continuous and high-purity oxygen to users requiring respiratory support by drawing in ambient air, separating and concentrating the oxygen within it. The design of the device indicates its suitability for home use or in healthcare facilities. Technical details such as “FLOW METER” and “OXYGEN OUTLET” on it confirm that it is a medical respiratory device.

General Condition and State

The product in the visual is in excellent physical condition. The overall appearance of the device suggests that it has either not been used at all or has been used very little. No significant discoloration, yellowing, or dirt is observed on its white plastic casing. The protective packaging around the humidifier chamber still being present is an important detail supporting this observation. The originality of the device is evident from the clarity of the brand logo and model text and the print quality on it.

• Quantity Information: The visuals show 1 oxygen concentrator, and on the device, still in its original packaging, 1 respiratory mask (or nasal cannula) and its tubing are present.
• Originality: The logo, inscriptions, and overall craftsmanship quality leave a strong impression that the product is original.

Detailed Physical Examination

No negative findings were observed during a detailed examination of the device’s external casing and mechanical components.

• Physical Deformation: There are no scratches, cracks, dents, or impact marks on the device’s body. The surface is smooth and clean.
• Mechanical Components:
  • Control Panel and Buttons: The power button and other control buttons appear new, with no signs of wear.
  • Flow Adjustment Knob: The rotary knob used to adjust oxygen flow is intact and in place.
  • Flow Meter: The glass tube and the ball inside it, which measure in liters/minute (L/min), are clean and undamaged.
  • Humidifier Chamber: The humidifier housing with a transparent lid and the lid itself are intact. The fact that the white protective foam/fabric packaging surrounding the chamber has not been removed indicates that the device may be unused.

Electronic Components and Accessories

The electronic components of the device and its accompanying accessories have been examined based on visual evidence.

• Screen and Control Panel: There is a digital LCD screen on the front face of the device. Since the device is off in the images, information such as whether the screen is working or the hours of use cannot be seen. Around the screen, there are indications like “TIMER (minutes)” and “HOURS (hours)” showing the timer and total operating time.
• Connection Ports: On the front panel, there is a port named “OXYGEN OUTLET” designed for oxygen output. The physical condition of this port is good.
• Accessories: On the device, there is an unopened respiratory accessory (likely an oxygen mask or nasal cannula) and connection tubing in a sealed and transparent bag. The newness of this accessory reinforces the positive impression of the device’s overall condition.

Label and Code Information

Basic information identifying the device is accessible in the visuals. However, detailed technical labels are not visible.

• Brand: All times
• Model: 7F-5B
• Serial Number, REF Code, Lot Number: No label containing this information is present in the examined visuals.

Potential Risk Assessment

Based on the findings observed in the visuals, no existing fault or risk factor indicating a potential for malfunction in the near future has been identified in the device. The casing, buttons, connection points, and accessories of the product are in excellent condition. The physical state of the device does not pose any obstacle to safe and trouble-free use. On the contrary, its extremely well-maintained and clean condition is a positive indicator of the device’s potential longevity.
