Description

Technical Field

[0001] The invention relates to the technical field of critical care nursing, in particular to a critical care turning device. Background Art

[0002] Critical care is professional care for patients with serious illnesses, multiple organ failure, or who require special medical equipment support. Critical illness refers to a disease state that is relatively serious and requires close monitoring and treatment. It usually includes serious abnormal vital signs such as respiratory failure, heart failure, liver and kidney failure, etc. Critically ill patients need to receive close monitoring and treatment in the hospital, including infusion, oxygen, mechanical ventilation and other treatment methods. Since critically ill patients lie in bed for a long time, they need to be turned over regularly. If they are not turned over on time, the muscles and tissues are compressed for a long time, blood circulation is blocked, causing muscle and tissue hypoxia, leading to cell death, which will aggravate the condition and even cause muscle and tissue necrosis in severe cases. Therefore, it is very important to turn bedridden patients on time.

[0003] Based on the above, the inventors have found that the existing critical care turning device has the following main deficiencies. For example, the existing turning device slowly turns the patient's back by flipping the plate to support the patient, thereby turning the patient's body. Since the plate is hard, the patient's pain will be aggravated if he lies on the upper end for a long time. At the same time, when there is no one to take care of the patient, the patient who needs to turn over cannot do it alone. Summary of the Invention
