Description

Breathing mask Technical Field The utility model relates to the field of breathing masks, in particular to a breathing mask. Background A respiratory mask is a device for assisting breathing or protecting a respiratory system, and is widely applied to a plurality of fields such as medical treatment, first aid, industry, aviation and the like. It is generally composed of a mask body, a gasket, a breather valve, a connecting tube, etc. In the medical field, the breathing mask can be used for treating respiratory diseases, such as providing oxygen therapy for patients with chronic obstructive pulmonary diseases, helping patients with sleep apnea-hypopnea syndrome to carry out noninvasive ventilation, and can be used for delivering anesthetic gas and oxygen to the patients in operation anesthesia, and rapidly providing high-concentration oxygen for the patients in emergency treatment. During patient anesthesia, mask displacement resulting in a less tight seal is a serious problem. The primary function of the anesthetic mask is to deliver anesthetic gases and oxygen to the patient to maintain the patient's anesthetic state and normal breathing during surgery. Once the mask is displaced and sealed inaccurately, anesthetic gas leakage can be caused, so that the actual inhaled anesthetic gas dose of a patient is insufficient, the anesthetic effect is affected, the patient can possibly have consciousness recovery, pain perception and other conditions in the operation, pain can be brought to the patient, normal operation of the operation can be disturbed, and the anesthetic gas leakage into the operation environment can also produce certain harm to health of medical staff.
