Abstract

Pulsoximetry sensor with two sensor elements, which are fixed to a support body, which has fastenings for the sensor elements interconnected by means of a web, so that the two sensor elements can be placed on opposite sides of the hand or foot.

Claims

1. A pulsoximetry sensor comprising:

a support body including two fastenings;

an arcuate elastic web interconnecting the two fastenings of the support body so that the two fastenings are adapted to be positioned on the opposite sides of a hand or a foot when the support body is fixed to the hand or foot; and

first and second sensor elements, each of which is located in a depression of a respective one of the two fastenings so that the sensor elements are retained opposite one another,

wherein the support body is adapted to be fixed to the body part by means of a flexible clip shaped onto the first fastening and which is oriented in the same direction as the web, so that the support body is adapted to be laterally engaged on the foot or hand and is held by the clip, which is guided via the second fastening and which spans the foot or hand.

2. A pulsoximetry sensor according to claim 1, wherein on top of one of the fastenings is provided at least one recess for receiving the clip and for holding the clip in its position.

3. A pulsoximetry sensor according to claim 2, wherein on top of one of the fastenings are provided two displaced recesses each having two facing edges, the recesses and facing edges interacting with the clip to hold the clip in position by a clamping action.

4. A pulsoximetry sensor according to claim 2, wherein the recess has a dove-tail cross-section.

5. A pulsoximetry sensor according to claim 4, wherein the clip has lateral corrugation.

6. A pulsoximetry sensor according to claim 1, wherein the clip has corrugations on top and/or bottom corrugations and is guided on the edge of the depression by at least one ring holding the clip in position.

7. A pulsoximetry sensor according to claim 1, wherein on the fastening or on the web is provided a detent in which the clip engages with corresponding locking openings.

8. A pulsoximetry sensor according to claim 7, wherein the support body is made from silicone.

9. A pulsoximetry sensor according to claim 3, wherein the recess has a dove-tail cross-section.

10. A pulsoximetry sensor according to claim 1, wherein the clip has lateral corrugation.

11. A pulsoximetry sensor according to claim 5, wherein the support body is made from silicone.

12. A pulsoximetry sensor according to claim 1, wherein the support body is made from silicone.
