Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a prone position turning device. Background Art
[0002] The prone position is a professional medical term, which is a posture where the front of the body faces downwards, the arms are bent and placed on both sides of the head, the legs are straightened, and the head is turned to one side. Prone position ventilation is a method of improving ventilation by changing the patient's body position. Usually, when the human body is in the prone position, the lung tissue in the thoracic cavity is more likely to move downward, thereby enhancing the ventilation effect. Patients with lung diseases can improve the ventilation-perfusion ratio of the lungs through prone position ventilation, cause some atrophied alveoli to reinflate, and under the action of gravity, it is beneficial to drain the secretions in the trachea outward. Through prone position ventilation, the hypoxic state of patients with lung diseases can be improved, and the success rate of treatment can be increased.
[0003] Before performing prone position ventilation, the patient needs to first maintain the prone position to promote alveolar reinflation and drain the secretions in the trachea outward. During prone position ventilation, it needs to be operated by experienced medical staff according to the different conditions of the patient. During the ventilation process, the medical staff needs to closely monitor the patient's vital signs and respiratory parameters; in addition, during the ventilation process, it is also necessary to strengthen the skin care of the patient and regularly turn the patient's body to maintain their comfort and avoid the occurrence of complications. The current problem is that patients with severe conditions cannot turn themselves to the prone position independently and need the help of multiple medical staff to turn. However, manual turning is not well-controlled in terms of strength and is likely to cause harm to the patient.
[0004] Therefore, how to design a prone position turning device that can help the patient turn to the prone position and does not require the operation of multiple medical staff is a problem that needs to be solved in current clinical practice. Summary of the Utility Model
