Technical Field

[0001] The utility model relates to the technical field of surgical anesthesia, in particular to an anesthesia mask fixing belt. Background Art

[0002] In modern medicine, when performing surgery, anesthesiologists often use gas anesthetics to relieve patients' pain. Gas anesthetics are delivered and used through an anesthesia mask, where the anesthesia mask is a breathing mask covering the patient's mouth and nose, and then connected to the breathing and anesthesia machine to introduce anesthetic gas. The anesthetic gas enters the patient's respiratory system and then achieves the effect of anesthetic nerves. Anesthetics can effectively reduce the patient's pain during surgery, avoid abnormal activities caused by pain during surgery, and ensure the smooth progress of the operation.

[0003] The anesthesia mask is usually used in conjunction with a mask fixing strap, which can ensure that the anesthetic gas effectively enters the patient's respiratory system, better fix the anesthesia mask to the patient's mouth and nose, and can effectively reduce the leakage of anesthetic gas, thereby ensuring a better anesthesia effect.

[0004] At present, most anesthesia mask fixing straps are tied or connected to the patient's ears, the back of the head, or are integrated through ordinary elastic band structures. However, in actual operation, due to the different face shapes, ear sizes, and specific ear positions of patients, the usage experience is poor. This is mainly because the ordinary fixing strap structure is not easy to move and adjust the tightness, which often causes strangulation to the patient's ears or cheeks, resulting in poor comfort and the risk of anesthetic leakage.
