Title: Improvements in or relating to breathing apparatus for semi-closed circuit respiration
IPC: A61M16/10
Filed: 1958-06-02
Abstract: 876,184. Respiratory appliances. DRAGER, O. H. June 2, 1958 [May 31, 1957], No. 17585/58. Class 81 (2). A forced inhalation apparatus for artificial respiration has a pressure-relief valve, the outlet through which is restricted by a throttle which may be adjustable. In the apparatus described, a bellows 1 is alternately compressed and extended to cause flow of air through a non- return valve 6 to the face mask connection 14 and, on the expansion stroke, to withdraw air from the lungs through a carbon dioxide absorber 9 and non-return valve 15. Throughout the operation of the apparatus a mixture of anµsthetic gas and oxygen is admitted to the system through a pipe 8. The pressurerelief valve 11 is connected to the tube 5, adjacent the mask connection 14, and the passage leading to it is throttled by an adjustable needle valve 10. The valve 11 is set to open at a pressure only slightly above atmospheric but during the positive pressure stroke the rate of loss of gas is restricted by the valve 10, thereby ensuring that the pressure rises gradually to a maximum and immediately falls off again. This avoids the drawbacks of arrangements in which the lung pressure rises rapidly to a maximum, determined by a relief valve, and remains at that value for an appreciable time until the pump reduces the overall pressure below that value.
