Abstract
A vacuum drainage bottle includes a chamber for receiving fluids from a patient and a pressure indicator (9,21) for measuring the pressure in the chamber. Prior to use, the pressure indicator is isolated from the chamber by means of a breakable seal. The seal may be in the form of a recessed membrane (43), which may be ruptured by depressing the pressure indicator, causing a ball (45) to bear against the membrane (43).
