Abstract

The present invention relates to an imaging device designed with the intent of visualizing subcutaneous structures within an organism. Visualization of subcutaneous structures will increase the speed and accuracy with which medical treatments requiring insertion of instruments into these structures can be performed. Especially fluid insertions into or extractions from an organism will be facilitated as the device is adapted to be placed upon the organism in a manner giving continued full mobility for the recipient and operator of the device.

Claims

1. An imaging device designed with the intent of visualizing subcutaneous structures in a body of a recipient, comprising:

a) at least one light emitting source illuminating a selected area of body surface, underlying tissue and subcutaneous structures,

b) at least one camera enabled detection system recording an image of said illuminated subcutaneous structures,

c) at least one display means rendering a recorded image of the illuminated subcutaneous structures, wherein the display is an integrated part of the device, and wherein said display is on a surface of the device facing away from the body surface of the recipient

d) said device being adapted to be placed directly upon the recipient,

wherein said at least one light source emits light in an angle to the camera enabled detection system, said angle being between 5 degrees and 160 degrees,

e) wherein said at least one light source is embedded in a strap or a hinged flap attached to said device, and/or said at least one light source rests at a distance from the body surface, wherein said distance is provided for by a membrane, and/or wherein the at least one light source provides for trans-illumination.

2. The device according to claim 1, wherein the device is fastened to the recipient by a fastening means.

3. The device according to claim 1, where the subcutaneous structures are blood vessels.

4. The device according to claim 1, where the subcutaneous structures are veins.

5. The device according to claim 1, where the subcutaneous structures are veins wherein a hypodermic needle is inserted.

6. The device according to claim 1, wherein the light source illuminates the body surface in a reflective mode.

7. The device according to claim 1, wherein the light source illuminates the body surface in a trans-illuminating mode.

8. The device according to claim 1, wherein at least one light source is a light source emitting visible light.

9. The device according to claim 1, wherein at least one light source emits yellow, orange or red light.

10. The device according to claim 1, wherein at least one light source is an infrared light emitting source.

11. The device according to claim 1, wherein the light source is selected from the group of consisting of light emitting diodes (LEDs) and laser diodes (LDs).

12. The device according to claim 1, wherein the light sources are arranged in at least one angle to the camera.

13. The device according to claim 1, wherein at least one light source is in direct contact with the body surface of the recipient.

14. The device according to claim 1, wherein the device comprises a means for filtering or deflecting the reflected light.

15. The device according to claim 1, wherein the camera enabled detection system is an electronic digital camera.

16. The device according to claim 1, wherein at least one display is placed facing away from the body surface of the recipient.

17. The device according to claim 1, wherein all the components of the device are comprised within a frame no larger than 350 cm³.

18. The device according to claim 1, wherein the positioning of at least two cameras allow for the visualization of subcutaneous structures in three dimensions.

19. The device according to claim 1, wherein the device comprises an ultrasound emitting source and an ultrasound detection system.

20. The device according to claim 1, wherein the device comprises a least one port for a remote power supply.

21. The device according to claim 1, wherein the device comprises at least one digital storage means.

22. The device according to claim 1, wherein the device comprises at least one assembly for communication purposes selected from the group of:

ports for plug-in devices, ports for wire transfer, means for wireless communication.

23. The device according to claim 1, wherein the device comprises at least one wireless communication means.

24. The device according to claim 1, wherein the recipient, the device is adapted to be placed upon, is a human being.

25. A method of visualizing subcutaneous structures in a body, comprising the steps of:

a) emitting light onto a selected area of body surface, hereunder lying tissue and subcutaneous structures,

b) detecting the reflected or transilluminated light by camera enabled detecting means and recording an image of illuminated subcutaneous structures,

c) displaying the image of illuminated subcutaneous structures,

d) wherein these step are performed with a device as defined in claim 1 being adapted to be placed directly upon the recipient.

26. The method according to claim 25, wherein a device as defined in claim 1 is used for visualizing subcutaneous blood vessels prior to and during injecting the tip of a hypodermic needle into said vessels.

27. The method according to claim 25, wherein the device as defined in claim 1 is used for visualizing subcutaneous blood filled structures for the purpose of identifying an individual thereby.
