Abstract

The invention discloses a pressure injury preventive sickbed. The sickbed comprises a rack, wherein an upper bed board and a lower bed board are arranged on the rack, and a plurality of air vents areformed in the upper bed board and the lower bed board; a first driving mechanism is arranged in the rack, and drives the upper bed board to turn over through a linkage mechanism; a second driving mechanism and a massage ventilation mechanism are also arranged in the rack; the massage ventilation mechanism comprises rotating shafts rotationally arranged at the bottom of the rack, at least two concave parts are arranged at the top end of each rotating shaft, the upper parts of the rotating shafts are sleeved with sliding sleeves, convex parts matched with the concave parts on the rotating shaftsare arranged on the inner end surfaces of the sliding sleeves; a limiting rack matched with the sliding sleeves is arranged on the rack, and extrusion blocks are arranged at the top ends of the sliding sleeves; the second driving mechanism drives the rotating shafts of the massage ventilation mechanism to rotate, so that the sliding sleeves slide up and down in the vertical direction of the limiting rack, and the sliding sleeves drive the extrusion blocks to penetrate the corresponding air vents in the lower bed board to perform corresponding axial movement. The sickbed has good pressure injury preventive effect.

Description

technical field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a pressure injury prevention hospital bed. Background technique

[0002] Pressure injury is a common clinical complication of critically ill patients or elderly patients who have been bedridden for a long time. It is local tissue damage caused by factors such as pressure, friction, shear force, and moisture. It often occurs at bone prominences, especially Occurs on the sacrum, heel, and ischium, presenting as intact skin or open sores. The occurrence of pressure injury can cause unbearable pain to the patient, increase the risk of infection, and even cause death. In order to prevent the occurrence of pressure injury, patients are often instructed in clinic to change their lying position frequently and perform local massage to prevent the occurrence of pressure injury.

[0003] However, the overall air permeability of the existing hospital bed is poor, and th...
