Document Type and Number:
Japanese Patent JPS59101159
Kind Code:
A
Abstract:
An artificial respirator of a high-frequency oscillation ventilation type is provided which is free from a risk of increasing pressure in the airways. The respirator comprises a double communication tube with inner and outer tubes. One of the tubes is utilized for feeding a respiration or anesthetic gas to the airways through an endotracheal cannula, and the other tube is connected to a communication tube in which two jet air injection tubes are provided. The first jet air injection tube is utilized for injecting a jet respiration gas to thereby transmitting high-frequency oscillations to the respiration or anesthetic gas. The second jet air injection tube is utilized for injecting a jet respiration gas toward outside of the communication tube from therewithin thereby to decrease the pressure in the communication tube and hence in the airways.
