Pressure sore prevention mattress

Abstract

A pressure sore prevention mattress comprises one or more mattress units hinged in sequence and control devices; each mattress unit comprises a bottom plate, a plurality of bed boards and lifting mechanisms, wherein the bed boards are arranged above the bottom plate in a lifting manner, and each lifting mechanism is connected between the corresponding bed board and the bottom plate; the control devices are separately connected with the lifting mechanisms of the mattress units and are used for controlling all the lifting mechanisms to act alternately; the bed boards transversely extend and are longitudinally arranged to form a rectangular bed surface; each lifting mechanism comprises a plurality of lifting components, a screw rod and a motor, wherein the lifting components are connected between the corresponding bed board and the bottom plate and are arranged along the length direction of the bed board, each screw rod is transversely arranged on the corresponding lifting components horizontally, and each motor is used for driving the corresponding screw rod to rotate; each lifting component comprises two nuts, two upper link plates and two lower link plates, wherein the two nuts of each lifting component are arranged on the corresponding screw rod at intervals and are opposite in thread, the two upper link plates of each lifting component are hinged between the two corresponding nuts and the corresponding bed board, and the two lower link plates of each lifting component are hinged between the two corresponding nuts and the bottom plate; through forward and reverse rotation of each screw, the two corresponding nuts are driven to move oppositely, so that the upper link plates and the lower link plates are matched to prop up or lower the bed boards.

Description

technical field [0001] The invention relates to an anti-decubitus mattress. Background technique [0002] Some patients who need to rest in bed for a long time, because they cannot move and turn over by themselves, the local tissues of the body are under pressure for a long time, and the blood flow is blocked. Nurses need to turn over and massage the patient frequently, and the workload is very heavy. Some orthopedic patients will also experience increased pain due to the movement of their limbs. In view of the above problems, in order to prevent the occurrence of bedsores in long-term bedridden patients, the conventional practice is to use Air bed, but in actual use, because the purchase price of the air bed is expensive, the use process consumes electric energy, the continuous cost is high, the volume is large, and the effect is still not ideal, which makes the air bed difficult to be widely used in clinical practice, and the utilization rate is extremely low.
