Air cushion bed system and air charging and deflating pressure regulating system and method

Abstract

The invention discloses an air cushion bed system and an air charging and deflating pressure regulating system and method. The air charging and deflating pressure regulating system is used for the air cushion bed provided with at least two air pipelines, and the air charging and deflating pressure regulating system comprises an air charging and deflating device, a pressure detection unit and a control unit. The air charging and deflating device is used for charging or deflating air for the air cushion bed; the pressure detection unit is used for continuously detecting an instant pressure value of the air cushion bed; the control unit is used for obtaining the instant pressure value detected by the air cushion bed in a loading state according to the pressure detection unit, and whether the instant pressure value reaches the preset pressure value before setting time is up or not is judged; the control unit determines a first air charging and deflating strategy or a second air charging and deflating strategy according to judge results to control the air charging and deflating device to charge or deflate the air for the air cushion bed.

Description

technical field [0001] The present invention relates to a gas filling and deflation pressure regulating system and method, in particular to a gas filling and deflation pressure regulating system and method which can perform corresponding filling and deflation operations by detecting changes in load pressure. The present invention also includes an air bed system using the air inflation and pressure regulating system. Background technique [0002] Medical-grade air mattresses are mostly used for long-term bedridden patients, which can relieve the local pressure of patients when lying down and prevent bedsores. Therefore, when needed, the air mattress usually connects the inflation and deflation device to the air mattress through the gas transmission pipe, so that the inflation and deflation device and the air mattress form gas communication, so as to inflate or deflate the air mattress. [0003] Since the weight of each patient is different, the pressure exerted on the air ma...

[0005] However, it takes a lot of time for the patient to lie on the air bed until the pressure stabilizes. In addition, it takes a long time to wait for the pressure to stabilize, so the waiting time for the overall pressure adjustment process of the air bed is too long, not only It will cause waste of time and cost, and will bring users a bad experience
