An anti-pressure injury hospital bed

Abstract

The invention discloses an anti-pressure injury hospital bed, which comprises a frame, an upper bed board and a lower bed board are arranged on the frame, and a plurality of ventilation holes are arranged on the upper bed board and the lower bed board; a first driving mechanism is arranged in the frame , the first driving mechanism drives the upper bed board to turn over through the connecting rod mechanism; the second driving mechanism and the massage ventilation mechanism are also provided in the frame, the massage ventilation mechanism includes a rotating shaft arranged at the bottom of the frame, and at least two shafts are arranged on the top of the rotating shaft The upper part of the rotating shaft is covered with a sliding sleeve, and the inner end surface of the sliding sleeve is provided with a convex part that matches the concave part on the rotating shaft. There is an extruding block; the second driving mechanism drives the rotating shaft of the massage ventilation mechanism to rotate, and then the sliding sleeve slides up and down along the vertical direction of the limit frame, and the sliding sleeve drives the extruding block to pass through the corresponding air holes on the lower bed plate to perform corresponding movement. axial movement. The invention has good effect of preventing pressure injury.

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...

AI Technical Summary

Problems solved by technology

[0003] However, the overall air permeability of the existing hospital bed is poor, and the effect of preventing pressure injury cannot be achieved.

At the same time, manual methods are used to massage the patient or change the lying position, which is not only labor-intensive, but also costly
