Description

Mask special for artificial respiration

Technical Field

The invention belongs to the technical field of medical auxiliary instruments, and particularly relates to a mask special for artificial respiration.

Background

Artificial respiration is a treatment method which is urgently adopted when spontaneous respiration stops, and can provide oxygen supply for important organs of the body so as not to cause damage to the important vital organs due to hypoxia. There are two common methods of artificial respiration, namely mouth-to-mouth respiration and mouth-to-nose respiration. Mouth-to-mouth breathing is the most common way, in which a patient takes a supine position, a rescuer places his/her hand on the forehead of the patient, holds his/her nostril with his/her thumb and index finger, then deeply inhales a breath, opens the mouth to close the mouth of the patient, blows continuously 2 times to the mouth of the patient until the thorax is lifted, stops blowing, loosens the mouth of the patient, and releases the hand holding the nostril, turns the face aside, exhales with the ear with or without airflow, and deeply inhales a fresh air in preparation for a second blow, and when the patient has expired, starts the next same blow.

The biggest defect of mouth-to-mouth breathing mode is insanitation, if the patient still suffers from infectious diseases, the transmission of diseases is extremely easy to cause, so that a rescuer often generates psychological barriers possibly infected with the diseases, thereby influencing the rescue effect. The artificial respiration mask disclosed in the Chinese patent document CN 210020757U is characterized in that two elastic belts are arranged on a mask body, a breathing nozzle and a one-way valve are adhered on the mask body through strong adhesive, and an air inlet pipe and an air outlet pipe are arranged on the one-way valve. The sealing performance is good, the gas can not flow back, and the direct contact between the mouth and the mouth is avoided. The scheme has the defects that the breathing mouth is difficult to wrap the mouth of a patient, so that the breathing mouth is easy to leak from the mouth of the patient, namely, the problem of isolation between the mouth is solved, the air tightness is affected, and the rescuing effect is affected.
