Abstract

An epidermal dressing includes an appliance for linking an electromagnetic spectrum sensor with a cannula administering an intravascular infusate. The appliance includes a body and a fitting coupled to the body. The body is configured to space a connector of the cannula from the epidermis. The fitting includes a first arrangement that is configured to retain the electromagnetic spectrum sensor for sensing the infusate in perivascular tissue, and a second arrangement that is configured to release the electromagnetic spectrum sensor from the first arrangement.

Claims

1. A dressing for a cannula administering a fluid, the dressing comprising:

an appliance configured to link an electromagnetic spectrum sensor with the cannula, the appliance including a fitting having—

a first arrangement configured to retain the electromagnetic spectrum sensor for monitoring the fluid in perivascular tissue; and

a second arrangement configured to release the electromagnetic spectrum sensor from the first arrangement; and

a membrane configured to overlie portions of the cannula and the appliance.

2. The dressing of claim 1 wherein the appliance comprises a wing projecting from the fitting and being configured to contiguously engage the cannula.

3. The dressing of claim 2 wherein the wing and the membrane are configured to generally fix the cannula with respect to the appliance.

4. The dressing of claim 2, comprising a strip configured to secure the cannula with respect to the wing.

5. The dressing of claim 2 wherein the fitting has a higher resistance to deformation than the wing.

6. The dressing of claim 2 wherein the fitting includes a polypropylene homopolymer and the wing includes a thermoplastic elastomer.

7. The dressing of claim 2, comprising adhesive configured to bond the wing to an epidermis.

8. The dressing of claim 7 wherein the wing is configured to separate the cannula from the epidermis.

9. The dressing of claim 1 wherein the fitting comprises a chute extending along an axis between first and second ends, the chute being configured to receive the electromagnetic spectrum sensor in the first arrangement.

10. The dressing of claim 9 wherein the axis comprises a straight line and the chute is configured for guiding the electromagnetic spectrum sensor to translate along the axis.

11. The dressing of claim 9 wherein the first end is configured to pass the electromagnetic spectrum sensor when rearranging between the first and second arrangements.

12. The dressing of claim 9 wherein the appliance comprises a panel occluding the second end.

13. The dressing of claim 12 wherein the panel substantially prevents passage of solids, liquids, microorganisms, and viruses.

14. The dressing of claim 12 wherein the panel is approximately transparent to near-infrared signals.

15. The dressing of claim 1 wherein the membrane includes a peripheral edge configured to partially cincture the fitting.

16. The dressing of claim 1 wherein the membrane is configured to permit visual inspection of the cannula.

17. The dressing of claim 1 wherein the fitting comprises a latch configured to contiguously engage the electromagnetic spectrum sensor in the first arrangement.

18. The dressing of claim 17 wherein the latch is configured to disengage the electromagnetic spectrum sensor in the second arrangement.

19. The dressing of claim 1 wherein the appliance is biocompatible according to at least one of ISO 10993 and USP Class IV.
