Description

Technical Field

[0001] The utility model relates to the technical field of respirators, in particular to an artificial respirator. Background Art

[0002] Artificial respirator, also known as simple respirator or pressurized oxygen bag, is a simple tool for artificial ventilation. Compared with mouth-to-mouth respiration, artificial respirator has a higher oxygen concentration and is easy to operate. Especially when the patient is in critical condition and there is no time for tracheal intubation, artificial respirator can be used to directly supply oxygen, so that the patient can get sufficient oxygen supply and improve the hypoxic state of cell tissue.

[0003] The existing artificial respirator consists of an oxygen storage bag, an oxygen connecting pipe, a valve and a mask. When in use, the rescuer needs to hold up the neck of the rescued person with one hand and press down the forehead of the rescued person at the same time. Therefore, the existing artificial respirator requires at least two rescuers to operate. At the same time, due to the influence of the force of the neck being supported and the forehead being pressed, the airtightness between the mask and the face of the rescued person is difficult to effectively ensure. For this reason, we propose an artificial respirator that can be operated by one person and is conducive to improving the airtightness between the mask and the face of the rescued person.
