Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an artificial insufflation device for cardiopulmonary resuscitation. Background Art

[0002] If the patient's breathing or heart stops beating, cardiopulmonary resuscitation must be performed quickly. Otherwise, when the patient stops breathing and his heart stops beating, the blood cannot flow and cannot carry oxygen to the body's organs, which may cause necrosis of the body's organs, especially the brain. According to research, if the brain is deprived of oxygen for more than four minutes, it may cause necrosis of brain cells, and the extent of the damage is determined by the duration of hypoxia. If the hypoxia lasts for more than ten minutes, it is likely to cause irreparable damage to the brain, or even brain death.

[0003] However, respiratory infectious diseases are emerging one after another. When performing cardiopulmonary resuscitation on patients, medical staff will perform artificial respiration on patients. However, if the patients have respiratory infectious diseases, medical staff are likely to be infected by patients with respiratory infectious diseases during this process.

[0004] The utility model aims at solving the above problems and provides an artificial insufflation device for cardiopulmonary resuscitation. Utility Model Content
