Medwelt 7E-G Portable Suction Device Analysis Report

Device Description and Area of Use

The product in the image is a portable suction device of the Medwelt brand, model 7E-G. As understood from the phrase “Portable Phlegm Suction Unit AC/DC” on the product, this device is designed to clear a patient’s respiratory tract by aspirating body secretions such as phlegm. The device’s integrated carrying handle and AC/DC power support indicate that it can be used portably, both connected to a fixed power source and via its internal battery. These features suggest that the device is suitable for use in various settings such as home care, emergencies, or clinical environments.

General Condition

The general condition of the device, based on the examination of the visuals, is quite good. The product’s casing is clean, spotless, and shows no significant signs of wear. This indicates that the device has either never been used or has been used very little and with care. No negative conditions such as dust, dirt, or discoloration have been observed. The device generally has a well-maintained and new appearance.

Physical and Mechanical Analysis

The physical and mechanical components of the device have been examined in detail. No findings indicating any functional defect have been encountered.

• Casing: The cream-colored plastic casing of the device has no cracks, breaks, dents, or deep scratches. All parts fit together perfectly and exhibit a robust structure.
• Mechanical Components: The on/off switch on the front panel and the rotary knob labeled “Pressure Regulator,” used to adjust vacuum power, are physically sound and in place.
• Pressure Gauge: The dial and protective glass of the analog pressure gauge are clean and undamaged. The needle is at the zero position as it should be when the device is off.
• Carrying Handle: The carrying handle, integrated with the device casing, is sturdy and shows no signs of damage.
