Abstract

1,034,759. Valves. A. LAERDAL. May 28, 1965 [June 15, 1964], No. 22801/65. Heading F2V. [Also in Division A5] A valve for artificial respiration apparatus has a casing part 8 leading to a face mask and another casing part 1 connected to a bag of air or oxygen; a plastics diaphragm 13 provides two closure members controlling the flow of gas to and from the patient. Upon compressing the bag gas flows through a normally-closed slit 17 in the diaphragm apex to the patient, a shoulder portion 15 of the diaphragm being forced more tightly against an annular seating 11 to prevent any communication between the port 8 and exhaust ports 10. Obstruction in the patient's respiratory passages will be apparent since the bag will remain filled. Exhalation into the part 8 closes the slit 17 and unseats the shoulder portion 15 so opening the path to the exhaust ports 10 which are covered by an annular elastic ring 20, the inner edge of which is connected to the port 8. The valve casing is of transparent thermoplastic material.
