Abstract

The present invention relates to a medical device for intradermal or subcutaneous treatment of a patient, comprising: a piercing element to penetrate a skin portion of the patient; an illumination arrangement to illuminate the piercing element and/or to illuminate the skin portion prior and/or during a treatment process, wherein the illumination arrangement is further adapted to visually indicate a predefined treatment sequence of the treatment process.

Claims

1. A medical device for intradermal or subcutaneous treatment of a patient, comprising:

a piercing element to penetrate a skin portion of the patient;

an illumination arrangement to illuminate the piercing element and/or to illuminate the skin portion at least during a treatment process,

wherein the illumination arrangement is further adapted to visually indicate a predefined treatment sequence of the treatment process;

wherein the illumination arrangement comprising a control element adapted to at least partially correlate activation of the illumination arrangement with the predefined sequence of the treatment process.

2. The medical device according to claim 1, wherein the illumination arrangement is adapted to generate at least one light cone around the piercing element to illuminate the skin portion.

3. The medical device according to claim 2, wherein the illumination arrangement is adapted to generate various light cones of different cone angle.

4. The medical device according to claim 1, wherein the illumination arrangement comprises at least one light source of incandescent, gas discharge, electro-luminescent or stimulated emission type.

5. The medical device according to claim 1, wherein the illumination arrangement is adapted to indicate the beginning, the end or various distinct intermediate steps of the treatment process.

6. The medical device according to claim 5, wherein the control element is adapted to determine and/or to detect at least one distinct step of the treatment process.

7. The medical device according to claim 6, wherein the control element is adapted to modify and/or to deactivate the illumination of the illumination arrangement within a predefined delay after reaching of or determination of the distinct step of the treatment process.

8. The medical device according to claim 1, wherein the illumination arrangement is adapted to indicate the treatment sequence by at least two different illumination colours and/or by way of different illumination sequences.

9. The medical device according to claim 1, comprising a drug delivery device for injecting a liquid medicament.

10. The medical device according to claim 9, wherein the drug delivery device comprises:

a housing to accommodate a cartridge at least partially filled with a medicament to be injected,

a drive mechanism comprising a piston rod to become operably engaged with a piston of the cartridge.

11. The medical device according to claim 9, further comprising a cartridge disposed in the housing.

12. The medical device according to claim 1, comprising a lancing device to pierce and/or to analyze biological fluid and/or biological tissue.

13. The medical device according to claim 1, wherein the illumination arrangement is coupled with a control element adapted to control and/or to initiate the treatment process.

14. The medical device according to claim 13, wherein actuation of the control element turns on the illumination arrangement for a predefined time interval.

15. A method of controlling an illumination arrangement of a medical device according to claim 1, comprising the steps of:

detecting at least one treatment sequence of a predefined treatment process to be executed by the medical device,

modifying the operation mode of an illumination arrangement of the medical device in response to the detection of the treatment processes, and

visually indicating at least one predefined treatment sequence of the treatment process by means of the illumination arrangement.
