Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an automatic turning device for prone ventilation of severe ARDS patients. Background Art

[0002] Severe ARDS is a serious respiratory disease that usually occurs quickly after being attacked by pathogenic factors and manifests as severe respiratory distress and hypoxemia. When respiratory distress is severe, medical staff need to perform assisted ventilation in the prone position.

[0003] For example, the Chinese patent document with publication number CN219289975U discloses a portable prone position hospital bed for improving lung ventilation, including a base plate, a bracket installed at the bottom of the base plate, the base plate is in a broken line shape, a groove is opened on the right side of the base plate, a first bed board is installed on the left side of the base plate, a second bed board is movably installed on the right side of the first bed board, a hydraulic rod is movably installed in the groove, the telescopic end of the hydraulic rod is movably connected to the lower wall of the second bed board, a ventilation and heating structure is installed between the base plate and the first bed board, and a prone structure is installed on the first bed board and the second bed board.

[0004] The portable prone position hospital bed for improving lung ventilation disclosed above has the following problems: since the prone position can reduce the load on the lungs during the treatment of severe ARDS patients, the patient's breathing movements can be effectively assisted. However, when the prone position hospital bed for improving lung ventilation is used, the chest cavity is supported, and the supporting state cannot be changed. Therefore, it does not simulate the auxiliary breathing mechanism of medical staff for the lungs, but is a fixed structure. When the patient uses it, the chest cavity is always squeezed. This is not a true and reasonable auxiliary lung ventilation structure. The prior art does not realize an auxiliary structure that provides assistance when needed and is in a stored state under normal conditions. The prior art is not easy to solve such problems. Therefore, there is an urgent need for an automatic turning device for prone ventilation of severe ARDS patients to solve the above problems. Summary of the invention
