An insulated housing is described which includes a means for holding a pair of electrical connectors in parallel. The housing includes a griping means which allows a person to either insert or remove the housing from a mating electrical connection. The housing also includes a 'living hinge' which, when closed, clamps on to the pair of electrical connectors to provide strain relief.

Hinged electrical connector

A quick disconnect connector for use with a system for measuring depth of anaesthesia of a patient. For this purpose, a probe is attached to a patient to detect esophageal contractions. The probe is connected to a patient station by means of flexible tri-lumen tubing. The patient station provides a pressure transducer, a source of pressurized air, and a thermistor connection, and in turn is operatively connected to a microprocessor which controls the entire operation. One conduit of the tubing enables communication between a liquid filled balloon within the probe and the transducer at the patient station. Another conduit enables an air balloon within the probe to be connected to the source of pressurized air. Still another conduit receives the electrical lead which extends to the thermistor. The connector is designed to be joined with the tri-lumen tubing at one end, and at its other end is provided with a positive locking construction enabling the probe to be rapidly connected to the source of pressurized air or rapidly disconnected therefrom. For this purpose, the patient station has a female receptacle which matingly receives a male bayonet style fitting on the connector and a resilient gasket on the receptacle is engaged by a terminal rim on the connector to thereby achieve a fluid tight junction.

Heat exchanger housing assembly

Transducer housing assembly for monitoring blood pressure and the like

A pressure transducer assembly is disclosed for directly monitoring pressure in a fluid which flows through the assembly. The assembly includes a housing defining a chamber therewithin and having an inlet port and an outlet port in fluid-flow communication with the chamber. An electrically insulated body element is sealed within the chamber dividing the chamber into a first chamber and a second chamber. The first chamber is in fluid-flow communication with the inlet and outlet ports. The second chamber is separated from the first chamber by a fluid-tight seal such that any fluid present in the first chamber cannot enter the second chamber. A pressure transducer sensor is secured in the insulated body and exposed to the first chamber such that the sensor can determine the pressure in a fluid in the first chamber and convert the pressure into electric impulses. The sensor is separated from the fluid in the first chamber by an insulating medium across which fluid pressure can be determined. Connected to the sensor are electrical conductors which extend through the insulated body and into the second chamber. The second chamber provides an engagement site for an electrical connector which can interconnect with the electrical conductors and provide an electrical path through which the electric impulses generated by the sensor can be transferred to a monitor.
