Abstract:
A single use system for measuring the pressure in a mammalian body utilizing an air-bladder communicating with a catheter lumen in a catheter that relies upon the connection of the catheter to a transducer housing to activate the air bladder, the system comprising:a transducer housing having a pressure transducer and having a means to activate the air bladder and a piercing element therein;a catheter connector, having a lumen communicating with the catheter lumen and an air vent and an air vent seal occluding the air vent in the catheter connector and, the connector being insertable in the transducer housing so that the seal and piercing element will at some time become mutually engaged to cause the piercing element to breach the seal and the nature of contact between the seal and the piercing clement is such that the seal is an effective pneumatic seal to ensure proper operation during the expected period of use the first time the connectors are joined, and so that the seal is no longer capable of occluding the vent thereafter when the two connectors are separated.
