Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for alleviating dry mouth of patients before and after surgery. Background Art

[0002] Not being able to eat or drink before surgery is also known as preoperative fasting. Its purpose is to avoid respiratory problems caused by accidental aspiration of vomit during anesthesia. Due to the sequence of operations, some patients need to wait a whole day, during which time patients will experience unbearable dry mouth. Some patients need to block their nasal cavity after surgery and breathe through their mouths, which aggravates the dry mouth. In clinical practice, for patients who are fasting from food and water, when dry mouth occurs before and after surgery, cotton swabs dipped in water or the back of a spoon dipped in water are often used to moisten the patient's lips to relieve the dry mouth. The amount of water on the back of the spoon is small and cannot provide relief all the time. Cotton swabs dipped in water are prone to dropping cotton wool, causing patients to have foreign bodies in their mouths. In addition, some postoperative patients cannot relieve the dryness on their own due to anesthesia or surgical procedures, so they feel uncomfortable and easily affect mood changes, which does not conform to the current concept of rapid recovery. Summary of the invention

[0003] In response to the above-mentioned technical problems, a device is provided for alleviating dry mouth of patients before and after surgery.
