Abstract

A Measurement device for medical applications is disclosed, comprising an intracorporeal sensor element (5), a extracorporeal evaluation unit and electrical connections (2, 6) between the sensor element (5) and the evaluation unit. The device comprises a flexible foil tape cable (1), which is intended for the electrical and mechanical connection of the evaluation unit with the sensor element (5) and a substrate (4), which is mechanically connected with the one end (3) of the foil tape cable (1) around the sensor element (1). The substrate (4) has an higher mechanical strength than the foil tape cable (1). The sensor element (5) is connected to electric cables (2) of the flexible foil tape cable (1) and the substrate (4) is enclosed with the sensor element (5) in a flexible mass (7).

Claims

1. A measurement device for medical applications through connection with an extracorporeal evaluation unit, the measurement device comprising the combination of an intracorporeal sensor element (5), a flexible foil tape cable (1) comprising means for dried electrical and mechanical connection of the evaluation unit with the sensor element, said foil tape cable having a given mechanical strength, the foil tape cable further comprising an electrical track (2) between the sensor element and the evaluation unit, a substrate (4) mechanically connected with one end (3) of the foil tape cable, the substrate having a mechanical strength greater than said given mechanical strength of the foil tape cable, the sensor element being connected to said electric tracks (2) of the foil tape cable, and a flexible mass (7) enclosing both the substrate (4) and the sensor element (5).

2. Measurement device according to claim 1, characterised in that said substrate is comprised of a carrier material (8) and the foil tape cable (1) is made of the material FR4.

3. Measurement device according to claim 1, characterised in that the substrate (4) is a FR4 substrate.

4. Measurement device according to claim 1, characterised in that the sensor element (5) is a pressure sensor or a combined pressure and temperature sensor.
