Abstract

A conformable medical sensor is provided that has particular applicability for positioning a pulse oximeter sensor relative to a patient appendage. In one embodiment, the sensor holder includes a patient engaging member that is plastically deformable to permit the sensor holder to be conformed to the patient appendage, and plastically deformable to provide a retention force relative to the patient appendage. For example, the engaging member may be bent into a first shape that disposes first and second portions of the sensor holder into an opposing relationship the for receiving a patient appendage therebetween. Once deformed, the engaging member may be elastically deformed to a second shape to provide a retention force so as to maintain the sensor holder and a sensor interconnected thereto in contact with the patient appendage. In another embodiment, and the sensor holder may include a deformable backing layer that is plastically and elastically deformable, as described above, together with a patient interface layer having a recess located for the receipt of the sensor therein.

5. The medical sensor holder of claim 4, wherein said resilient relative deflection creates a compressive force between said opposing first and second portions in said second shape.

6. The medical sensor holder of claim 1, wherein said engaging member further comprises:

a patient interface layer comprising a compressible material.

7. The medical sensor holder of claim 6, wherein said patient interface layer further comprises:

an adhesive material.

8. A method for positioning a medical sensor relative to a patient appendage, said method comprising the steps:

interconnecting a medical sensor to an appendage engaging member;

plastically deforming said appendage engaging member to a first shape, wherein first and second portions of said engaging member are disposed in a spaced opposing relationship;

elastically deforming said appendage engaging member from said first shape to a second shape, wherein said first and second portions are elastically deflected relative to one another causing a resilient restoring force therebetween;

inserting a patient appendage between said first and second portions while said engaging member is in said second shape; and

utilizing said resilient restoring force to apply a compressive force to said appendage.

9. The method of claim 8, wherein said step of plastically deforming said engaging member comprises bending said engaging member into a U-shaped member wherein said first and second portions are spaced.

10. The method of claim 9, wherein said step of elastically deforming said engaging member comprises applying an outward force between said spaced first and second members.

11. The method of claim 10, wherein said step of utilizing comprises releasing said outward force after said step of inserting.

12. A sensor holder for positioning a sensor relative to a patient appendage, comprising:

a deformable backing layer, said backing layer being plastically deformable from a first configuration to a second configuration and elastically deformable from said second configuration to a third configuration;

a patient interface layer having a first surface interconnected to said backing layer and a second inside surface for interfacing with a patient appendage; and

a sensor recess located on said inside surface for selectively receiving a sensor.

13. A sensor holder as claimed in claim 12, further comprising:

an adhesive material on said patient interface layer.

14. A sensor holder as claimed in claim 12, wherein in said second configuration, a first portion and a second portion of said sensor holder are disposed in an opposing relationship.

15. A sensor holder as claimed in claim 14, wherein said sensor holder generally comprises a U-shape when said first and second portions are in said opposing relationship.

16. A sensor holder as claimed in claim 14, wherein in said third configuration said first and second portions of said sensor holder are elastically deformed relative to one another.

17. The sensor holder as claimed in claim 14, wherein first and second sections of said sensor recess are located on said first and second portions of said sensor holder.

18. The sensor holder as claimed in claim 12, wherein said recess is configured to:

matingly receive a correspondingly-shaped sensor.

19. The sensor holder as claimed in claim 12, wherein said recess has a depth formed into said patient interface layer to allow said inside surface of said patient interface layer and a top surface of a sensor to be substantially planer upon application of said sensor to said sensor recess.

20. The sensor holder as claimed in claim 12, wherein said recess further comprises a retainer for selectively attaching a sensor to said sensor holder.

21. The sensor holder as claimed in claim 20, wherein said retainer comprises an adhesive coating on the bottom of said recess.

22. The sensor holder as claimed in claim 21, wherein said adhesive coating is covered with a removable release sheet that may be selectively removed prior to receiving a sensor.

23. The sensor holder as claimed in claim 12, wherein at least one of said deformable backing layer and said patient interface layer is opaque.

24. The sensor holder as claimed in claim 12, wherein said patient interface layer is a compressible material.

25. A method for positioning a sensor relative to a patient appendage, said method comprising the steps:

providing a deformable sensor holder having at least one sensor recess on an inside patient interface surface;

locating a sensor in said recess;
