Air Supply for Medical Mattress for Preventing Press Ulcer

摘要

the present invention is to prevent pressure ulcers for patients with pressure ulcer prevention for alternating pressure mattresses dependent on supplies of such, are connected to the shift unit having a plurality of flotation mattress form a plurality of flow channels to form a passage through which the air flow, the flow passage is connected with each of the air pump for supplying air to each flow path, the flow path of each phase is provided in the air pump is selectively opened and closed when the drive is provided on the supply valve, each of the flow path for supplying air to the flow path, the flow path and the discharge valve is opened and closed so that air is discharged from the floating channel, the respective is provided on the flow path, to control the opening degree of the flow control valve opening degree, each of the air pump, the supply valve, exhaust valve and the opening degree of the pressure supply device for pressure sore prevention alternating mattress support comprising a controller for controlling the control valve is provided, the overshooting phenomenon is prevented when the air pad is expanded, the amount of air that the air pad is pressed by the weight of the patient leakage can be supplemented always maintain a constant flotation of improving the patient''s comfort, this effect There is.
