Abstract
1, 028, 935. Artificial respiration apparatus. BLEASE ANAESTHETIC EQUIPMENT Ltd. Nov. 8, 1962 [Nov. 9, 1961], No. 444/65. Divided out of 1, 028, 934. Heading A5T. The subject matter of this specification is substantially identical with that described in Specification 1,028,934, but the claims are concerned with an artificial respiration apparatus comprising a large variable volume chamber e.g. bellows 32, connected to a face mask 56, and a small variable volume chamber e.g. bellows 14, between the large variable volume chamber and a gas supply 4, a control valve 34 between the chambers being opened by a tripping mechanism in response to changes in the volume of the small chamber, and the volume of the small chamber at which the valve opens being dependant on the instantaneous volume of the large chamber.
