Controlling Method for Air Supply Profile for Medical Mattress for Preventing Pressure Ulcer

摘要

the present invention is to prevent pressure ulcers for patients with pressure ulcer prevention for alternate ways to boost the profile of the control of as , wherein the plurality of flow paths, each connected to a respective support channel so as to supply or exhaust the air to form part of the alternate channel support mattress comprising a plurality of support channels, the air pump for supplying air to each flow path, the flow path of each phase and having a supply for supplying air from the air pump to the valve support channel, each is provided on a flow path comprising an opening regulating valve that controls the discharge valve, the opening degree of the flow path which is opened and closed so that the air is discharged alternately In the air supply to the mattress support, the air is discharged from a plurality of the support channel of the at least one expansion step of expanding by supplying air to the inflated inflatable flotation keep maintaining a state of the channel, the expanded air pad is provided a control method of the step is made, including the shrinkage shrink plurality of support channels intersect alternately as support for pressure sore prevention profile formed so as to expand and contract alternately, the overshooting phenomenon is prevented when the air pad is expanded , the amount of air that leaks air pad is pressed by the weight of the patient can be supplemented to maintain a constant always has the effect of improving flotation comfort of patients.
