Description

a liftable hospital bed

Technical field:

The invention relates to medical equipment, in particular to a liftable hospital bed.

Background technique:

Pressure sores, also known as pressure ulcers or decubitus ulcers, are due to long-term pressure on local tissues, resulting in continuous ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. Skin pressure sores are a common problem in rehabilitation and nursing care. In order to make the long-term bedridden patient get rid of the puzzlement of pressure sore, the prior art adopts an air bed, that is, laying one deck of air cushion on the bed. However, the basic unit of the air cushion in the prior art is cylindrical, and a plurality of cylindrical basic units are arranged vertically to form an air cushion, and the patient feels uncomfortable lying on the air cushion, especially when the inflation and deflation equipment is pressed by a basic unit at intervals. When the constituent units inflate all the basic constituent units that make up the inflatable cushion in turn.

Invention content:

The technical problem to be solved by the present invention: in the prior art, the inflatable cushion composed of a plurality of cylindrical basic components arranged in a longitudinal manner is uneven, and the patient feels uncomfortable lying on the inflatable cushion.

The present invention provides following technical scheme:

A liftable hospital bed comprises an air cushion and a bed body, and the air cushion is laid on the bed body;

The air cushion includes a top material layer, a bottom material layer, side walls, and an external inflation pipe; the top material layer and the bottom material layer are arranged horizontally, and the side walls are vertically arranged, and the side walls include an upper side wall, a lower side wall, a left The side wall, the right side wall, the top material layer, the bottom material layer and the side wall form a sealed inflatable chamber, the external inflatable pipe is arranged on the upper side wall and the lower side wall, and the external inflatable pipe communicates with the inflatable chamber; The material of the top material layer is PVC, and the bottom material layer is made of rigid material;

A divider is provided in the air-filled chamber, and the divider is a double-layer structure. The divider of the double-layer structure includes a first divider layer and a second divider layer. The longitudinal section of the first divider layer and the second divider layer The longitudinal sections of the two separation belt layers are all in a V-shape lying down, and the small end of the first separation belt layer and the small end of the second separation belt layer are arranged opposite to each other; the upper top surface of the first separation belt layer and the second The upper top surface of the separation belt layer is fixed on the inner surface of the top material layer by pasting process, and the lower bottom surface of the first separation belt layer and the lower bottom surface of the second separation belt layer are fixed on the inner surface of the bottom material layer by pasting process; The dividing strip divides the plenum chamber into a plurality of plenum chamber units.

According to the above technical solution, the inflation and deflation equipment inflates the air into the inflatable chamber, and the top material layer has a tendency to bulge, but the separation belt pulls the top material layer, so that the top material layer cannot be bulged as a whole, and multiple inflatable chamber units According to the shape of the word "Tian", small pieces bulge up. Through the above technical solution, the top material layer is overall horizontal after the inflatable chamber is inflated, and a plurality of small bulges in the shape of "Tian" are bulged on the surface.
