In the second image, which shows the interior of the device, the WEINMANN brand has been identified on the electronic circuit board (PCB).

Applications

As understood from the IPAP, PEEP, Vt (Tidal Volume), O2, and lung symbols on the control buttons of the front panel, this device is a mechanical ventilator used to provide respiratory support to patients. It is designed for use with appropriate tubing and mask systems in conditions such as respiratory failure or sleep apnea.

Quantity Information

The images show 1 device front panel casing and 1 main electronic circuit board group (with connected sub-boards) mounted on this casing.

General Condition and Physical State

The product is not in the form of a complete device; it consists only of the front casing and the screen/keypad circuits integrated into this casing. The device’s rear casing, motor (turbine), power supply, and other internal components are not present in the images. The device is in used condition.
