摘要： A catheter tip pressure transducer for detecting the pressure in various portions of a living body accurately and safely comprises a pressure sensor disposed within the end portion of a catheter. The pressure sensor comprises a pressure sensitive diaphragm whereon strain gauges are formed by a diffusion method. The pressure sensor is mounted on an insulated supporting member without being secured firmly thereto. A protecting member made of silicone rubber fills the hollow portion of the catheter so as to isolate and protect the pressure sensor and the ambient body tissue.Pressure is accurately measured by the pressure sensor without being influenced by the thermal stresses which occur in the supporting member. Furthermore, electrical isolation and mechanical safety are obtained.

摘要： A disposable pressure transducer for measuring fluid pressure, which includes a sensor assembly in a housing. The housing includes a fluid chamber and a sensor-accommodating chamber which are formed integrally with each other. The sensor assembly comprises: a sensor chip for converting pressure into an electrical signal; an insulating board on which the sensor chip is mounted and which is provided with an integrated-circuit for processing an output signal of the sensor chip so that an external measuring device can read the signal; a cylindrical coupling lid which is bonded to the board in such a manner as to surround the sensor chip and which is fitted into a communication through-hole which provides communication between the fluid chamber and the sensor-accommodating chamber of the housing; a pressure-transmitting medium charged into the interior of the coupling lid so as to provide electrical insulation between the fluid chamber and the sensor chip; and an electrical cable connected to the board and electrically connected to the external measuring device.
