Abstract

In a transmission cable (1) for medical signal values, several single cables (2,5,6,7) of different cable type are integrated in a common cable sheath (3), wherein each cable type is configured for transmission of a particular medical signal value. The thus multifunctional transmission cable (1) is used in particular for integration of the signal values for temperature and nitrogen content in blood as well as ECG and blood pressure.

Claims

1. Transmission cable (1) for medical signal values, with several single cables (2,5,6,7,7′

) of different cable type and integrated in a common cable sheath (3), wherein each cable type is configured for transmission of a particular medical signal value.

2. Transmission cable according to claim 1, wherein one of the single cables is configured as flexible tube (2) for transmission of blood pressure values, and wherein there are provided a first number of single cables (7,7′

) for values commensurate with the nitrogen content in blood, a second number of single cables (5) for temperature values, and a third number of single cables (6) for ECG values.

3. Transmission cable according to claim 2, wherein the tube (2) is arranged in a central disposition, and wherein all remaining single cables (5,6,7,7′

) are arranged in an annular space (4) between the waveguide (2) and the cable sheath (3).

4. Transmission cable according to claim 3, wherein a screen (9) is provided between the annular space (4) and the cable sheath (3).

5. Transmission cable according to claim 3, wherein a bandage (10) is provided between the annular space (4) and the tube (2).

6. Transmission cable according to claim 3, wherein a number of filler elements (8) are arranged in the annular space (4).

7. Transmission cable according to claim 1, wherein a thermoplastic material is used as insulating material for the cable sheath (3).

8. A multifunctional signal transmission cable assembly, comprising:

a cable sheath; and

a cable arrangement received within the cable sheath and configured for transmission of different medical signal values.

9. The cable assembly of claim 8, wherein the cable arrangement includes a first cable in the form of a flexible tube for transmission of a signal commensurate with a blood pressure measurement, a plurality of second cables for transmission of a signal commensurate with a measurement of a nitrogen content in blood, a plurality of third cables for transmission of a signal commensurate with a measurement of temperature values, and plurality of fourth cables for transmission of a signal commensurate with ECG values.

10. The cable assembly of claim 9, wherein the first cable has an outer circumference and is arranged in a central disposition within the cable sheath at a distance to the cable sheath to thereby define an annular space therebetween, said second, third and fourth plurality of cables placed about the circumference of the first cable in the annular space between the first cable and the cable sheath.

11. The cable assembly of claim 10, and further comprising a screen disposed between the annular space and the cable sheath.

12. The cable assembly of claim 10, and further comprising a bandage disposed between the annular space and the first cable.

13. The cable assembly of claim 8, and further comprising at least one filler element for use in the presence of a vacant space between neighboring cables in the annular space for filling said vacant space.

14. The cable assembly of claim 13, wherein the cables of the cable arrangement have each a substantially same outer diameter, said filler arrangement including a filler having an outer diameter substantially corresponding to the outer diameter of each of the cables.

15. The cable assembly of claim 8, wherein the cable sheath is made of thermoplastic material.
