ALAeda Healthcare Limited · Model MT-A3-300
This medical device is an Air Pump, and also named as Alternating Control Unit or Alternating-Pressure Pump, it is always used with an Air Mattress together, and combines into a Mattress System (Alternating Air Pressure Mattress), its function is controlling the Air Mattress to be inflated and deflated alternatively with a setting cycle time.
Intended use: An electrically-powered device that forces ambient air into the parallel chambers of an alternating-pressure bed mattress overlay or an alternating-pressure chair cushion, for the timed alternation of chamber inflation and thereby exchange of patient contact points. The inflator, which may be referred to as a pump and may be programmable, ensures a regular exchange of the overlay/cushion pressure points for the patient.
