Abstract

A multipart, non-uniform patient contact interface and method of use are disclosed.

Claims

1. A patient interface assembly, comprising:

a substrate;

a plurality of three-dimensionally contoured electrically conductive patient contacts physically attached to a first side of the substrate, each of the plurality of patient contacts having a top surface and a curved side portion surface that is connected to the top surface and holds the top surface above the first side of the substrate;

an interconnecting circuit assembly on a side of the substrate opposite from the first side of the substrate that electrically connects the plurality of three-dimensionally contoured patient contacts; and

wherein the top surface and curved side portion surface of the plurality of patient contacts provide contact with an uneven contact surface when the patient interface assembly is placed against the uneven contact surface.

2. The assembly of claim 1, wherein each patient contact has a particular shape.

3. The assembly of claim 1, wherein each of the plurality of patient contacts has a same shape.

4. The assembly of claim 1, wherein the plurality of patient contacts have one or more different sizes.

5. The assembly of claim 4, wherein the differently sized contacts are connected to the substrate.

6. The assembly of claim 1, wherein each patient contact is a sensor.

7. The assembly of claim 6, wherein the sensor is one of an ECG sensor and a pulse oximeter.

8. The assembly of claim 1, wherein the plurality of patient contacts are selected from an ECG sensor and a pulse oximeter.

9. The assembly of claim 1, wherein each patient contact is an electrode.

10. The assembly of claim 1, wherein the plurality of patient contacts are one or more sensors and one or more electrodes.

11. The assembly of claim 10, wherein the one or more sensors are arranged in the configuration separately from the one or more electrodes.

12. The assembly of claim 10, wherein the one or more sensors are arranged in the configuration intermixed with the one or more electrodes.

13. The assembly of claim 1, wherein the plurality of patient contacts are spaced and make the patient interface assembly capable of flexing and conforming to the contours of the uneven surface when the patient interface assembly is placed on the uneven surface.

14. The assembly of claim 1, wherein the plurality of patient contacts further comprises one or more bar patient contacts and one or more button patient contacts.

15. The assembly of claim 1 wherein each of the patient contacts has a flat top surface and a curved portion extending from the top surface down to the first side of the substrate.

16. The assembly of claim 1, wherein the plurality of three-dimensionally contoured electrically conductive patient contacts further comprises a particular three-dimensionally contoured electrically conductive patient contact attached to the first side of the substrate with a space between the particular three-dimensionally contoured electrically conductive patient contact and an adjacent three-dimensionally contoured electrically conductive patient contact.
