Abstract

653,216. Anaesthetic apparatus. BLEASE, J. H. Nov. 15, 1948, No. 29674. [Class 81 (ii)] Anaesthetic apparatus comprises two carbon dioxide absorbent containers, connected to a rebreathing bag, and valve means for controlling the proportion of gases passing into and out of the bag, through the absorbent material in either or both containers. In the apparatus shown in the figure a face mask 20 is connected through inhaling and exhaling tubes 18<1> to a body comprising two carbon dioxide absorbent containers 2 mounted on a hollow member 1. Each container has a rotary valve, controlled by a pointer arm 36 whereby gas passing to or from the mask may be passed through the absorbent container 2 to the hollow member 1, and thence to the breathing bag 26, or the container itself may be byepassed. Intermediate settings of the valves allow corresponding proportions of the gases to be passed through the absorbent material. The member 1 is provided with a clamp for mounting on a suitable support and the containers 2 .are held on it by securing screws 35 so as to be readily removable for recharging. The central member 1 has four communicating external pipe unions, one of which is used for the byepass connection referred to above, one for the breathing bag 26, one for a pressure gauge 27 and one for a supply of anµsthetic gas. This arrangement may be varied as required and the direction of gas flow through the containers may be changed by interchanging the connections of the pipes 18<1>.
