ABSTRACT:
The apparatus includes a container (26) having an open upper end into which is fitted a stopper (20). From the lower peripheral surface of the stopper (20) depends a membrane (24) which forms a chamber containing one calibrating fluid (28). The stopper (20) is adapted to permit a medical probe to extend therethrough, the hub (16) needle (14) and sensor (12) of which extend beneath the membrane (24). Another calibrating fluid (30) is located in the container (26) beneath the membrane (24). The membrane (24) is capable of maintaining a fluid-tight seal as it is punctured by the needle (14) and of re-sealing itself when the needle (14) is removed, without permitting contamination of the one calibrating fluid (28) by the other calibrating fluid (30) and vice versa.
