Technical Field

[0001] The utility model relates to a medical appliance, in particular to a neck pillow used for opening the airway of an anesthetized patient during surgery. Background Art

[0002] During painless gastroenteroscopy or surgery, many patients will experience respiratory depression under sedation. Medical staff usually hold both sides of the patient's mandible with their hands to open the airway and make the patient breathe smoothly. However, it will be very tiring for medical staff to hold the mandible with their hands for a long time, which increases their workload.

[0003] Therefore, how to design a neck pillow that can replace manual support of the mandible to allow patients to breathe smoothly and reduce the workload of medical staff has become an urgent problem to be solved in the field of medical devices. Utility Model Content
