HOSPITAL BED AND GAS MATTRESS UNIT FOR HOSPITAL BED

摘要

A hospital bed comprises gas mattress units, connecting pipe devices and a gas supplying-releasing device. The gas mattress units each have an inner layer and an outer layer. The inner layer is an airbag. The outer layer is a laminated fabric. The laminated fabric encloses the airbag. The airbag internally defines a first gas receiving space. A second gas receiving space is defined between the laminated fabric and the airbag. The connecting pipe devices and the gas supplying-releasing device are in communication with the gas mattress units, allowing a gas to be introduced into and released from the first gas receiving space. The first and second gas receiving spaces enable the hospital bed to bear high internal pressure and thus be durable, thereby lessening the durability requirement of the laminated fabric.
