Abstract

An epidermal dressing includes a barrier film and a fitting that cooperates with a sensor emitting and detecting near infrared signals for monitoring an intravascular infusion. The barrier film overlies an epidermal insertion site for a cannula administering the intravascular infusion. The fitting includes a first arrangement that retains the sensor and a second arrangement that releases the sensor from the first arrangement.

Claims

1. A dressing for an insertion site of an intravascular infusion, the dressing comprising:

a pane configured to overlie the insertion site; and

a frame coupled with the pane, the frame consisting of an approximately homogeneous chemical compound and including a first portion having (i) a first arrangement configured to retain an electromagnetic spectrum sensor for monitoring the intravascular infusion and (ii) a second arrangement configured to release the electromagnetic spectrum sensor from the first arrangement.

2. The dressing of claim 1 wherein the pane comprises an occlusive film that is at least one of transparent and translucent to visible light.

3. The dressing of claim 2 wherein the occlusive film is configured to substantially prevent passage of solids, liquids, microorganisms, and viruses.

4. The dressing of claim 2 wherein the occlusive film is biocompatible according to ISO 10993.

5. The dressing of claim 1 wherein the pane comprises a reticle configured to measure changes proximate the insertion site.

6. The dressing of claim 5 wherein the reticle is configured to overlie the insertion site.

7. The dressing of claim 5 wherein the reticle comprises at least one of a set of concentric arcs, a geometric shape, a set of parallel lines, and a color gradient.

8. The dressing of claim 1 wherein the frame has a higher resistance to deformation than the pane.

9. The dressing of claim 1 wherein the frame includes a second portion cincturing the pane.

10. The dressing of claim 1 wherein the frame includes a third portion configured to contiguously engage a lead of the electromagnetic spectrum sensor in the first arrangement.

11. The dressing of claim 1 wherein the frame includes a fourth portion configured to cooperate with a cannula administering the intravascular infusion.

12. The dressing of claim 11 wherein the fourth portion comprises a notch configured to receive a hub of a cannula administering the intravascular infusion.

13. The dressing of claim 1, comprising adhesive configured to attach the pane over the insertion site.

14. A dressing for an insertion site of an intravascular infusion, the insertion site being disposed on a patient, the dressing comprising:

a pane configured to overlie the insertion site;

a fitting having a first arrangement configured to retain an electromagnetic spectrum sensor for monitoring the intravascular infusion and a second arrangement configured to release the electromagnetic spectrum sensor from the first arrangement; and

a frame coupling the pane with the fitting;

wherein the pane, the fitting and the frame are configured to cincture a portion of the patient.

15. The dressing of claim 14 wherein the frame consists of an approximately homogeneous chemical compound.

16. The dressing of claim 14 wherein the frame comprises a resilient band
