Abstract

A subcutaneous access device of the invention comprises: a multi-layered structure capable of use in a medical imaging procedure; a light source for transillumination of a body portion of interest of a patient'"'"'s body; and an attachment portion for attaching the device to the patient'"'"'s body in a manner such that the body portion of interest is outwardly exposed on a side of the patient'"'"'s body opposite the light source. The device facilitates hands-free transillumination of the body portion of interest. Kits for subcutaneous access comprise the subcutaneous access device and a light detector for detecting light emitted from the subcutaneous access device.

Claims

1. A subcutaneous access device comprising:

a multi-layered structure capable of use in a medical imaging procedure;

a light source for transillumination of a body portion of interest of a patient'"'"'s body; and

a non-adhesive attachment portion configured to attach the device to the patient'"'"'s body in a manner such that the body portion of interest is outwardly exposed on a side of the patient'"'"'s body opposite the light source,

wherein the multi-layered structure comprises a conformable material comprising foam on a side of the device from which light is transmitted opposite the light source, such that the conformable material aids in prevention of light leakage from the light source.

2. The subcutaneous access device of claim 1, wherein the light source emits light having a wavelength of about 0.1 micron to about 1,500 microns.

3. The subcutaneous access device of claim 1, wherein the light source is coupled to a corresponding power source.

4. The subcutaneous access device of claim 3, wherein the light source comprises a portable power source.

5. The subcutaneous access device of claim 4, wherein the light source comprises a battery-powered light emitting diode or chemiluminescent source.

6. The subcutaneous access device of claim 1, wherein the device is configured for attachment to a patient'"'"'s body in a manner such that the body portion of interest is between the light source and a corresponding light detector.

7. The subcutaneous access device of claim 1, wherein the attachment portion comprises at least one buckle.

8. The subcutaneous access device of claim 1, wherein the attachment portion comprises a hook-and-loop fastener.

9. The subcutaneous access device of claim 1, wherein outwardly exposed edges of the multi-layered structure comprise a reflective or absorbing material for redirecting of light in relation to the body portion of interest.

10. The subcutaneous access device of claim 1, wherein the device provides hands-free transillumination of the body portion of interest.

11. The subcutaneous access device of claim 1, wherein the device is disposable.

12. The subcutaneous access device of claim 1, wherein the device is capable of multiple effective uses.

13. A kit for subcutaneous access, comprising:

the subcutaneous access device of claim 1; and

a light detector for detecting light emitted from the subcutaneous access device.

14. The kit of claim 13, wherein the light detector comprises a low-level light detector.

15. The kit of claim 13, wherein the light detector comprises night vision goggles.

16. Use of the kit of claim 13 for access of a subcutaneous structure, comprising steps of:

providing the kit of claim 13;

utilizing the kit by positioning the subcutaneous access device on the patient'"'"'s body such that the body portion of interest is outwardly exposed on a side of the patient'"'"'s body opposite the light source; and

,

detecting light emitted from the subcutaneous access device using the light detector.

17. Use of the kit of claim 13 for access of a subcutaneous structure, comprising steps of:

providing the kit of claim 13;

utilizing the kit by positioning the subcutaneous access device on the patient'"'"'s body such that the body portion of interest is outwardly exposed on a side of the patient'"'"'s body opposite the light source; and

,

detecting light emitted from the subcutaneous access device using the light detector,

wherein such use is proximate a battlefield.

18. Use of the kit of claim 13 for access of a subcutaneous structure, comprising steps of:

providing the kit of claim 13;

utilizing the kit by positioning the subcutaneous access device on the patient'"'"'s body such that the body portion of interest is outwardly exposed on a side of the patient'"'"'s body opposite the light source; and

,

detecting light emitted from the subcutaneous access device using the light detector,

wherein such use is in a forward surgical unit of a temporary battlefield installation.

19. Use of the kit of claim 13 for access of a subcutaneous structure, comprising steps of:

providing the kit of claim 13;

utilizing the kit by positioning the subcutaneous access device on the patient'"'"'s body such that the body portion of interest is outwardly exposed on a side of the patient'"'"'s body opposite the light source; and

,

detecting light emitted from the subcutaneous access device using the light detector,

wherein the subcutaneous access device is configured to be attached to the patient'"'"'s body such that the body portion of interest is between the light source and the light detector.

20. Use of the kit of claim 13 for access of a subcutaneous structure, comprising steps of:

providing the kit of claim 13;

utilizing the kit by positioning the subcutaneous access device on the patient'"'"'s body such that the body portion of interest is outwardly exposed on a side of the patient'"'"'s body opposite the light source; and

,

detecting light emitted from the subcutaneous access device using the light detector,

wherein the body portion of interest is transilluminated hands-free.

21. The subcutaneous access device of claim 1, wherein at least one layer of material capable of being securely attached at opposite ends thereof laterally extends from the subcutaneous access device.

22. The subcutaneous access device of claim 1, wherein the attachment portion of the device comprises an elastic sleeve or cuff having a sufficiently smaller diameter than a limb to which the device is to be applied.

23. The subcutaneous access device of claim 22, wherein the elastic sleeve or cuff is inflatable.

24. The subcutaneous access device of claim 1, wherein the device comprises a watch configuration.

25. The subcutaneous access device of claim 1, wherein outwardly exposed edges of the multi-layered structure comprise an absorbing material for redirecting of light in relation to the body portion of interest.

26. The subcutaneous access device of claim 1, wherein the attachment portion of the device comprises at least one of laces, strings, and bands.

27. The subcutaneous access device of claim 1, wherein the attachment portion of the device comprises a band.

28. The subcutaneous access device of claim 1, wherein the conformable material comprises a first foam boundary.

29. The subcutaneous access device of claim 28, wherein the conformable material comprises a second foam boundary fitted within the first foam boundary.

30. The subcutaneous access device of claim 1, further comprising tabs positioned around outwardly exposed edges of the multi-layered structure within the device, wherein the tabs are opaque to light emitted from the light source during use of the subcutaneous access device.

31. The subcutaneous access device of claim 1, wherein the non-adhesive attachment portion comprises an opening for accessing the subcutaneous structure illuminated by the light source without having to traverse the subcutaneous access device itself when the subcutaneous access device is attached to the patient'"'"'s body.
