respirator

Abstract

The invention provides an artificial respirator. A motor is connected with a speed change gear box in a transmission mode. The speed change gear box is connected with a first transmission shaft and a second transmission shaft at the same time in a transmission mode. The first transmission shaft is connected with a first eccentric wheel in a transmission mode, and the second transmission shaft is connected with a second eccentric wheel in a transmission mode. The side wall of a shell is provided with a first mounting opening and a second mounting opening. The first mounting opening is internally provided with a first elastic rubber piece corresponding to the chest of a patient in use and capable of being concave in the upper portion and convex in the lower portion. The side, where the first elastic rubber piece is located, of the shell is fixedly connected with a chest binding belt. The second mounting opening is internally provided with a second elastic rubber piece capable of being concave in the upper portion and convex in the lower portion in a closed mode. The first eccentric wheel and the second eccentric wheel correspondingly make contact with and are connected with the first elastic rubber piece and the second elastic rubber piece in a transmission mode. An air bag is connected outside the side, where the second elastic rubber piece is located, of the shell in a closed mode, and the air bag is connected with an intake valve and an air outlet valve in a closed mode. The air outlet valve is communicated with an air outlet connection pipe in a closed mode, and the air outlet connection pipe is connected with a mask in a closed mode.

Description

technical field [0001] The invention relates to a medical device, in particular to an artificial ventilator. Background technique [0002] When a person dies due to heartbeat and respiratory arrest for some reason, resulting in loss of heart function and lung function, people usually use artificial respiration to restore heartbeat and breathing, and promote blood oxygen to flow through various organs. Recover heart and lung functions to save patients' lives. [0003] The artificial respiration currently adopted has the following disadvantages: [0004] 1. Artificial respiration requires two or more specially trained personnel. One person presses the patient's chest with a certain rhythm, and the other blows air into the patient's body mouth-to-mouth with a certain rhythm. The two coordinate. Due to different factors such as the patient's physical constitution and the time of entering the dead state, the time from artificial respiration until the patient is rescued is also ...

AI Technical Summary

Problems solved by technology

When performing artificial respiration, even for specially trained personnel, it is difficult to grasp parameters such as compression frequency, compression depth and insufflation frequency, and it is difficult to meet the standards of the World Health Organization

[0006] 3. When doing artificial respiration, since the artificially insufflated gas is the exhaust gas discharged from the rescuer's lungs, the oxygen content is low and the carbon dioxide content is high, and the blood oxygen obtained by the patient's various organs is only 10% of the normal demand. 30%, far from meeting the needs of body function recovery

[0007] 4. Mouth-to-mouth artificial respiration may also cause the spread of respiratory diseases
