Background
The Weinmann SomnoComfort 2, WM 24400 and WM 24465, and its sister machine, the Weinmann SomnoComfort 2e machine, WM 24405, are continuous positive airway pressure (CPAP) machines that help assist individuals that have respiratory disorders while they sleep. The company also has similar machines that are positive airway pressure (PAP) machines named the Weinmann SomnoBalance, WM 27400, and the Weinmann SomnoBalance e, WM 27420.
This device is used through the patient's airways being stabilized with applied pressure through a mask they were while sleeping. This product is safe for anyone aged 12 and up. There are different parts to the machine that allow for it to work appropriately. These pieces are a filter, breathing tube, mask, and pressure sensor.
With its use being for medical purposes, the device has specific servicing and disinfecting instructions. It should be serviced every 2 years or 5000 operating hours, whichever comes first. All of the following parts of the CPAP machine should be disinfected on a regular basis; unit housing, filter compartment cover, cover, power supply, and power supply cable. The filter on the device also needs to be replaced regularly. Finally, the pressure measuring device needs to be checked regularly to ensure it has not changed pressures. All cleaning can be done while repairing, when device is expected to be used with a new patient, or while in use if used for extended period of time.
