Document Type and Number:
WIPO Patent Application WO/2022/070907
Kind Code:
A1
Abstract:
Provided is a novel artificial respirator that can be used for cardiopulmonary resuscitation without requiring an electric drive source. An artificial respirator 1 is equipped with: a tube 2 having a ventilation channel 2e formed therein; a relief valve 3; and a spontaneous breather valve 4. The tube 2 comprises a main port 2b which allows a patient's inhalation and exhalation to pass therethrough, a relief valve port 2c which is connected with the main port 2b via the ventilation channel 2e, and a spontaneous breather vale port 2d which is connected with the main port 2b via the ventilation channel 2e. The relief valve 3 is provided to the relief valve port 2c and configured to be opened according to the pressure in the ventilation channel 2e so as to be able to release the pressure by causing the ventilation channel 2e to be connected with the outside of the tube 2. The spontaneous breather valve 4 is provided to the spontaneous breather vale port 2d and configured to enable the patient to inhale when being opened and causing the ventilation channel 2e to be connected with the outside of the tube 2 in response to the inhalation pressure generated as a result of spontaneous respiration.
