PCT No. PCT/DK91/00011 Sec. 371 Date Jul. 6, 1992 Sec. 102(e) Date Jul. 6, 1992 PCT Filed Jan. 14, 1991 PCT Pub. No. WO91/10465 PCT Pub. Date Jul. 25, 1991.An air reservoir (4) intended for regulating the pressure in the sealing cuff of a respiration catheter has a wall consisting of an elastic membrane (3). The reservoir also functions as a pressure gauge, the elastic membrane when inflated being caused to contact a semitransparent plate (2) which is firmly connected with a rigid part (1) of the reservoir. At contact between the membrane and the plate, indicator rings on the membrane become visible through the semitransparent plate.
