Abstract

A noninvasive photoplethysmographic sensor platform for small animals provides a spring biased sensor clip, wherein at least one side of the sensor clip is provided with a saddle faced clip face member. The saddle shape of the clip face member may have a hinge end, toward the hinge of the clip, which is longer in the longitudinal direction of the clip and shorter in depth than the distal end. The shorter distal end side (measured longitudinally) of this saddle shape facilitates the ability to align the transmitted and received light with the bone, while the overall saddle shape of the facing provides a physical grip to capture enough tissue to prevent the clip from relocating over time while it is attached to the limb. The shorter hinge end side (depth-wise) also allows the clip to close when it is fully assembled. The edges of the saddle shaped clip are preferably rounded off to prevent the contusions of the tissue that may result from long-term contact. This saddle faced feature works well on only one side of the clip.

Claims

1. A noninvasive sensor platform for small animals includes sensor clip, wherein at least one side of the sensor clip is provided with a saddle faced clip member having a sensor coupled thereto and having laterally extending projections at distal ends of the clip member, wherein each laterally extending projection has a generally concave face.

2. The noninvasive sensor platform according to claim 1 wherein the sensor clip includes a pivot.

3. The noninvasive sensor platform according to claim 2 wherein saddle faced clip face member is provided only on only one side of the clip.

4. The noninvasive sensor platform according to claim 3 further including an integral diffuser into the clip face member which is aligned with one of the transmission or receiving source on the clip, wherein the diffuser includes a substantially encapsulated diffuser material provided within a diffuser pocket formed in the clip face member.

5. The noninvasive sensor platform according to claim 4 wherein the laterally extending projection at the pivot end of the clip face member has a shorter height than the laterally extending projection at the opposed end of the clip face member.

6. The noninvasive sensor platform according to claim 5 wherein the laterally extending projection at the pivot end of the clip face member has a longer longitudinal length from the sensor than the laterally extending projection at the opposed end of the clip face member.

7. The noninvasive sensor platform according to claim 2 further including an integral diffuser into the clip face member which is aligned with one of the transmission or receiving source on the clip, wherein the diffuser includes a substantially encapsulated diffuser material provided within a diffuser pocket formed in the clip face member.

8. The noninvasive sensor platform according to claim 7 wherein the laterally extending projection at the pivot end of the clip face member has a shorter height than the laterally extending projection at the opposed end of the clip face member.

9. The noninvasive sensor platform according to claim 8 wherein the laterally extending projection at the pivot end of the clip face member has a longer longitudinal length from the sensor than the laterally extending projection at the opposed end of the clip face member.

10. The noninvasive sensor platform according to claim 2 wherein the laterally extending projection at the pivot end of the clip face member has a shorter height than the laterally extending projection at the opposed end of the clip face member.

11. The noninvasive sensor platform according to claim 10 wherein the laterally extending projection at the pivot end of the clip face member has a longer longitudinal length from the sensor than the laterally extending projection at the opposed end of the clip face member.

12. The noninvasive sensor platform according to claim 2 wherein the laterally extending projection at the pivot end of the clip face member has a longer longitudinal length from the sensor than the laterally extending projection at the opposed end of the clip face member.

13. A noninvasive photoplethysmographic sensor platform for small animals includes a pivoted spring biased sensor clip, wherein at least one side of the sensor clip is provided with a saddle faced clip member having a photoplethysmographic sensor coupled thereto and having laterally extending projections at distal ends of the clip member, wherein each laterally extending projection has a generally concave face.

14. The noninvasive photoplethysmographic sensor platform according to claim 13 wherein saddle faced clip face member is provided only on only one side of the clip.

15. The noninvasive photoplethysmographic sensor platform according to claim 14 further including an integral diffuser into the clip face member which is aligned with one of the transmission or receiving source on the clip, wherein the diffuser includes a substantially encapsulated diffuser material provided within a diffuser pocket formed in the clip face member.

16. The noninvasive photoplethysmographic sensor platform according to claim 14 wherein the laterally extending projection at the pivot end of the clip face member has a shorter height than the laterally extending projection at the opposed end of the clip face member.

17. The noninvasive sensor photoplethysmographic platform according to claim 16 wherein the laterally extending projection at the pivot end of the clip face member has a longer longitudinal length from the photoplethysmographic sensor than the laterally extending projection at the opposed end of the clip face member.

18. The noninvasive photoplethysmographic sensor platform according to claim 13 further including an integral diffuser into the clip face member which is aligned with one of the transmission or receiving source on the clip, wherein the diffuser includes a substantially encapsulated diffuser material provided within a diffuser pocket formed in the clip face member.

19. The noninvasive photoplethysmographic sensor platform according to claim 13 wherein the laterally extending projection at the pivot end of the clip face member has a shorter height than the laterally extending projection at the opposed end of the clip face member.

20. The noninvasive photoplethysmographic sensor platform according to claim 13 wherein the laterally extending projection at the pivot end of the clip face member has a longer longitudinal length from the photoplethysmographic sensor than the laterally extending projection at the opposed end of the clip face member.
