背景技术Background technique
一旦人体因为疾病导致长期躺卧在病床上时，往往会因为人体体重长时间压迫，造成人体与床面接触的部位因为长时间血液循环不良，而有组织坏死的褥疮现象。为避免病人得褥疮，最有效的办法就是让病人躺卧交换充气式气垫床，该种交换式气垫床中区分有可交换充气与排气的气囊条，利用气体交换充、排气，可对病人身体达到交替且暂时不接触的减压作用，借此降低褥疮发生的机率。Once the human body lies on the hospital bed for a long time due to disease, it will often be oppressed by the body weight for a long time, resulting in the phenomenon of decubitus ulcers with tissue necrosis at the parts in contact with the bed surface due to poor blood circulation for a long time. In order to prevent the patient from getting bedsore, the most effective way is to let the patient lie down and exchange the inflatable air mattress. The patient's body achieves alternating and temporarily non-contact decompression, thereby reducing the chance of decubitus ulcers.

Wherein, when the air enters the pressure bag 92, if the air is saturated, the pressure bag 92 can be expanded, thereby pushing the switch pushing plates 93 on both sides to move, so that the induction switch can generate induction; however, the traditional pressure bag 92 type structure, Limited by material and structural factors, there are often problems with inaccurate movements and affecting the sensing results. Furthermore, the existing control valve 9 must be equipped with a trident pipe 94, and there is room and necessity for improvement in terms of overall efficacy, convenience of assembly, and cost reduction.
