Pressure transducer for measuring the pressure of a fluid, in particular for invasive blood pressure measurements
First Claim
1. A pressure transducer for measuring the pressure of a fluid, in particular for invasive blood pressure measurements, the pressure transducer comprising:
- a housing having a first chamber and a second chamber that are separated from one another in fluid-proof fashion, wherein the first chamber contains a pressure measuring element that may be charged with a fluid having a pressure to be measured and the second chamber contains electronic connection means for connecting an electric cable to an electrical conductor that is connected to the pressure measuring element, and wherein the pressure measuring element is fastened onto a flat substrate, the electric conductor being arranged on the substrate and extending laterally to contact points on the edge of the substrate;
the electronic connection means comprising a plug-in connector;
the second chamber of the housing being accessible from the outer side of the housing via an opening that serves for accommodating the plug-in connector;
the substrate lying centrally in the opening, so that both sides of the substrate lying in the second chamber are accessible via the opening;
the plug-in connector being provided with two parallel tongues between which the substrate may be accommodated, whereby one tongue is provided with electric spring contacts that may be brought in contact with the contact points of the substrate, said electric spring contacts being positioned on the side of said one tongue that faces the other tongue;
the substrate being held by a housing cover that lies parallel to said substrate; and
the parallel tongues enclosing the housing cover and the substrate between them.

Abstract
A pressure transducer for measuring the pressure of a fluid, in particular for invasive blood pressure measurements, comprises a housing with two chambers that are separated from one another in a fluid-proof fashion, whereby the first chamber accommodates a pressure transducer that is fastened onto a substrate and may be charged with the pressure of the fluid to be measured. The substrate lies in both chambers and has contact surfaces for the direct connection of an electric plug-in connector within the region of the second chamber. This plug-in connector comprises parallel tongues between which the substrate and a housing cover may be accommodated. One of the tongues carries electric spring contacts.
