Pressure wire assembly
First Claim
1. Pressure sensor wire assembly for measuring pressure inside a body of a patient, the assembly comprises:
- a pressure sensor element for measuring pressure and to generate a pressure sensor signal in response of said pressure;
a pressure sensor wire having said pressure sensor element at its distal portion, and adapted to be inserted into the body in order to position the sensor element within the body,a sensor signal adapting circuitry, being an integrated part of said assembly, wherein the pressure sensor signal is applied to the adapting circuitry that is adapted to automatically generate an output pressure signal, related to the sensor signal, in a standardized format such that the measured pressure is retrievable by an external physiology monitor, characterized in thatthe assembly further comprises an external pressure sensor arranged in the assembly to measure the pressure outside the patient'"'"'s body and to generate external pressure values in dependence thereto, the external pressure values are applied to a pressure compensation means, in said assembly, adapted to generate a compensation value reflecting the external pressure variation during a measurement procedure, wherein the output pressure signal is compensated by said compensation value prior to the output pressure signal being applied to the external physiology monitor.

Abstract
Pressure sensor wire assembly for measuring pressure inside a body of a patient, the assembly comprises a pressure sensor element for measuring pressure and to generate a pressure sensor signal in response of said pressure, and a pressure sensor wire having said pressure sensor element at its distal portion, and adapted to be inserted into the body in order to position the sensor element within the body. In addition is arranged a sensor signal adapting circuitry, being an integrated part of said assembly, wherein the pressure sensor signal is applied to the adapting circuitry that is adapted to automatically generate an output pressure signal, related to the sensor signal, in a standardized format such that the measured pressure is retrievable by an external physiology monitor. The assembly further comprises an external pressure sensor arranged at the assembly to measure the pressure outside the patient'"'"'s body and to generate external pressure values in dependence thereto, the external pressure values are applied to a pressure compensation means, in the assembly, adapted to generate a compensation value reflecting the external pressure variation during a measurement procedure, wherein the output pressure signal is compensated by said compensation value prior to the output pressure signal being applied to the external physiology monitor.
