Abstract

An arrangement for fixing a medical-technical sensor, particularly a pulsoximeter sensor, to a patient'"'"'s body part includes a carrier for supporting a sensor and a longitudinal opening for receiving the body part. The carrier includes a foam material part elastically deformable for the fixing. The deformation provides a force-accumulation arrangement. The medical-technical sensor for measuring physiological data can be combined with such arrangement. The sensor includes optical electronic measuring parts arranged on the carrier.

Claims

1. An arrangement for attaching a medical-technical sensor to a patient'"'"'s body part, comprising:

a carrier including an elastically deformable foam material part having a longitudinal direction, said foam material part being preformed as at least a partial tubular body;

a longitudinal opening in said foam material part extending in the longitudinal direction for receiving the body part;

slits extending in said foam material part radially relative to said longitudinal opening; and

a sensor support on said carrier.

2. An arrangement according to claim 1 wherein

said foam material part is a cylinder.

3. An arrangement according to claim 2 wherein

said cylinder is a right circular cylinder.

4. An arrangement according to claim 1 wherein

said foam material part is at least partially conical and tapers in the longitudinal direction.

5. An arrangement according to claim 1 wherein

said slits originate at said longitudinal opening and extend in the longitudinal direction to define at least two arcuate segments.

6. An arrangement according to claim 5 wherein

said slits extend radially through at least one-half of a thickness of said foam material part.

7. An arrangement according to claim 5 wherein

said segments are unitarily connected with one another by a peripheral portion of said foam material part.

8. An arrangement according to claim 1 wherein

said foam material part has a continuous, homogeneous, uninterrupted peripheral portion.

9. An arrangement according to claim 1 wherein

said longitudinal opening has a shape corresponding to the body part to be received therein.

10. An arrangement according to claim 1 wherein

said foam material part comprises a transverse opening forming said sensor support.

11. An arrangement according to claim 1 wherein

said carrier comprises an exterior with at least one part mounting a connection coupled to the sensor.

12. An arrangement according to claim 1 wherein

said foam material part is surrounded by a rigid sheathing.

13. An arrangement according to claim 12 wherein

said sheathing is formed of metal.

14. An arrangement according to claim 12 wherein

said sheathing is formed of plastic.

15. An arrangement according to claim 12 wherein

said sheathing is formed of separable parts that can be opened to receive said foam material part.

16. An arrangement according to claim 1 wherein

said foam material part is colored with a dye corresponding to an optical electronic measurement performed by the sensor.

17. A medical-technical sensor attachable to a patient'"'"'s body part, comprising:

a carrier including an elastically deformable foam material part having a longitudinal direction, said foam material part being preformed as at least a partial tubular body;

a longitudinal opening in said foam material part extending in the longitudinal direction for receiving the body part;

slits extending in said foam material part radially relative to said longitudinal opening; and

a sensor supported by said carrier.

18. A medical-technical sensor according to claim 17 wherein

said sensor comprises at least one optical transmitter and at least one optical receiver arranged on opposite sides of said carrier.

19. A medical-technical sensor according to claim 17 wherein

said foam material part is essentially impermeable to radiation of said sensor.

20. A medical-medical sensor according to claim 19 wherein

said foam material part is impermeable to said radiation by a correspondingly suitable color.
