Abstract

A medical monitoring system, such as an oximetry system, applies an attachment for securing an optical probe to a measurement site. The attachment has an elongated support with a first end and a second end, and a dedicated area in proximity of the first end. The dedicated area receives an optical probe and includes a material that is transparent for light emitted and received by the optical probe. The dedicated area mountably receives the optical probe on the material so that in use, the material is positioned between the optical probe and a surface of a measurement site. The optical probe may be factory-mounted to the dedicated area of the attachment as a ready-to-use sensor. In the alternative, the attachment may be available as an individual component, or as a part of a kit including the attachment and the optical probe.

Claims

1. A probe for non-adhesively attaching to a measurement site, comprising:

an elongated support having a first end and a second end, the support comprising;

at least one attachment element in proximity of one of said ends, wherein the at least one attachment element is configured to attach with a second portion of said support to non-adhesively secure an optical probe to a measurement site; and

a dedicated area in proximity of the first end and configured to receive the optical probe, the dedicated area comprising a material different from said support that is transparent for light emitted and received by the optical probe; and

a disposable optical probe comprising a standalone adhesive-type optical probe which is configured to adhesively attach to a measurement site independent of said support;

wherein the disposable optical probe is mounted on the dedicated area so that during measurement, the material is positioned between the optical probe and a surface of a measurement site.

2. The probe of claim 1, wherein the support is configured to allow wrapping the support around the measurement site.

3. The probe of claim 2, said attachment element comprising a tongue extending from the second end of the support.

4. The probe of claim 1, wherein the support includes a soft foam padding.

5. The probe of claim 4, said attachment element comprising a tongue extending from the second end of the support, the tongue comprising hooks to cooperate with a surface of the soft foam padding in a hook-loop securing mechanism.

6. The probe of claim 1, wherein the support includes a tape.

7. The probe of claim 6, said attachment element in proximity of the second end and comprising an adhesive to cooperate with a surface of the tape.

8. The probe of claim 1, wherein the dedicated area is sized to allow passage of light emitted and received by an optical probe.

9. The probe of claim 1, wherein the support has at least one opening, and wherein the material is coupled to the at least one opening.

10. The probe of claim 9, wherein the material is mounted within the at least one opening by at least one of sewing, gluing and welding.

11. The probe of claim 10, wherein the material is a two-part element, and wherein the parts are spaced apart at a predetermined distance.

12. The probe of claim 9, wherein the material includes an opaque portion that prevents light from traveling from one side of the material to another side of the material.

13. The probe of claim 12, wherein the material and the dedicated area have an elongate shape, and wherein the opaque portion comprises a stripe that extends between longitudinal sides of the material.

14. The probe of claim 1, wherein the material is a two-part element, and wherein the support has two openings, each opening sized to receive one of the parts.

15. The probe of claim 1, wherein the support comprises a bottom layer having a back surface and a bottom surface facing of the measurement site, and wherein at least a portion of the back surface supports the material.

16. The probe of claim 15, wherein the bottom layer has an opening, and wherein the material covers the opening.

17. The probe of claim 15, wherein the material is mounted to the back surface by at least one of sewing, gluing and welding.

18. The probe of claim 15, wherein the material includes an opaque material that reduces an amount of light that travels from one side of the material to another side of the material.

19. The probe of claim 18, wherein the material and the dedicated area have an elongate shape, and wherein the opaque portion comprises a stripe that extends between longitudinal sides of the material.

20. The probe of claim 15, wherein the bottom layer has two openings, each opening sized to allow passage of light, and wherein the material covers the openings.

21. The probe of claim 15, wherein the support further comprises a top layer, and wherein the transparent material is positioned between the top layer and the bottom layer.

22. The attachment of claim 1, wherein the disposable optical probe comprises a pulse oximetry disposable optical probe.

23. A method of securing an optical probe to tissue at a measurement site in order to determine at least one characteristic of the tissue, the method comprising:

mounting elements of a disposable optical probe on a transparent area of an attachment, wherein the optical probe comprises an adhesive-type optical probe capable of adhesive attachment to a measurement site independent of said attachment;

positioning elements of the optical probe mounted on the attachment at a measurement site; and

wrapping the attachment around the measurement site and securing the elements of the optical probe to the measurement site by attaching a first portion of said attachment with a second portion thereof to non-adhesively secure the probe to the tissue.
