Description

Technical Field

[0001] The invention relates to the technical field of turning-over auxiliary beds, in particular to a turning-over device for critically ill patients. Background Art

[0002] Severely ill patients usually have high-risk diseases that threaten their lives. Due to trauma, disease and other reasons, their physiological conditions have deteriorated rapidly and their lives are in danger. After rescue, they are usually arranged to be admitted to the Intensive Care Unit (ICU) for special nursing care. In this case, the patient is generally in a coma or unconscious state, and cannot freely control his body movements. Due to long-term bed rest, the most likely secondary injury is pressure sores. Due to the long-term compression of some tissues, ischemia and hypoxia cause partial tissue necrosis. In severe cases, the patient may die due to various complications when the immune system is weakened during the critical period.

[0003] Nowadays, in order to prevent patients from developing pressure sores due to long-term bed rest, nurses are usually required to turn patients over regularly. Since critically ill patients have no self-care ability, nurses need to do the turning of patients independently. When the patient's weight is large, the nurse's strength is very limited, which will make it impossible to turn the patient over. At this time, multiple nurses are required to work together to turn the patient over, which takes up a lot of medical resources. Therefore, a device that can assist patients in turning over is needed to prevent critically ill patients from developing pressure sores due to long-term bed rest. Summary of the invention

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The turning over auxiliary component is arranged inside the bed frame 1, and the turning over auxiliary component includes:

[0050] A motor 10, the motor 10 is arranged on the inner lower surface of the bed frame 1, and the output end of the motor 10 is belt-driven with a threaded rod 9, the end of the threaded rod 9 close to the motor 10 is rotatably connected with a fixed plate 14, the lower surface of the fixed plate 14 is fixedly connected to the inner lower surface of the bed frame 1, the threaded surface of the threaded rod 9 is also threadedly connected with a threaded block 23, the lower surface of the threaded block 23 is fixedly connected to a limiting block 25, the lower end side surface of the limiting block 25 is slidably connected to a limiting frame 24, and the lower surface of the limiting frame 24 is fixedly connected to the inner lower surface of the bed frame 1;
