Medical auxiliary artificial respirator
Technical Field
The invention relates to the technical field of medical instruments, in particular to an artificial respirator for medical assistance.
Background
After a coma patient or a patient with cardiac arrest gets rid of foreign matters in an airway, the patient needs to immediately perform artificial respiration if the respiratory tract is unblocked by a free-hand method, so as to ensure that oxygen is supplied to the patient uninterruptedly and prevent irreversibility damage of important organs caused by oxygen deficiency. Two common artificial respiration methods are mouth-to-mouth respiration and mouth-to-nose respiration.
