Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a prone position ventilation support bed with a fixed structure for thoracic surgery. Background Art

[0002] In postoperative care of thoracic surgery, prone ventilation is an important treatment method to improve the patient's oxygenation function, which can improve the patient's oxygenation and reduce lung complications.

[0003] However, patients usually have drainage tubes, infusion tubes and other tubes after surgery, making it difficult to maintain the traditional prone position, causing great discomfort to the patients. Moreover, after the patients change their positions such as turning over, their positions will move from the middle of the bed to both sides of the bed, and the nursing staff will need to move them back to the middle of the bed. This process is relatively laborious and requires cooperation between the patients and the nursing staff, which may increase the patients' pain and reduce their comfort.

[0004] Some clinical practices use fixed prone ventilation support devices, which lack adaptive design for the special needs of postoperative patients, have poor flexibility, and are difficult to adapt to the needs of patients of different body sizes. This causes the patient's body to be suspended in the prone position or excessive local pressure, further reducing comfort. At the same time, drainage tubes, infusion tubes and other pipelines lack effective fixation and are prone to traction, folding or falling off, increasing the risk of infection and affecting drainage effectiveness.
