Abstract

An insertion device with an underside for placing on the skin of a patient, which has a recess for an insertion needle. The insertion device has means for forming a skin surface rising like a step or slope and facing towards the recess, preferably bearing on the recess. The means for forming the step or slope may include first and second pressure areas for pressing the skin with the recess for the needle located between the first and second pressure areas. The device may be configured whereby a downwardly extending cutting plane, in which the insertion needle lies, intersects the first pressure area in a first line and the second pressure area in a second line, and wherein the first line in the vicinity of the recess extends at a greater height than the second line. At least one of the two pressure areas may be a strip.

Claims

1. An insertion device for use with a patient, the insertion device comprising:

a lower side for being placed on the skin of the patient, the lower side including a recess for an insertion needle held by the insertion device;

means for forming a skin area rising in the manner of a step or slope facing the recess; and

wherein the means for forming the skin area rising in the manner of a step or slope includes a first pressure area and a second pressure area adapted to be pressed against the skin, wherein the recess for the insertion needle is located between the first pressure area and the second pressure area, and wherein a sectional plane which extends from the top down and in which the insertion needle is located intersects the first pressure area in a first line and the second pressure area in a second line, and wherein the first line runs proximate the recess at a greater height than the second line;

wherein at least one of the two pressure areas is a strip; and

wherein the insertion device broadens in an upward direction, starting at the lower side.

2. The insertion device according to claim 1 wherein the insertion needle is covered by the first pressure area when the insertion needle is in a protruding state which is reached at the end of a feed motion when a puncture is made.

3. The insertion device according to claim 1 wherein the strip has a width of less than 1 cm.

4. The insertion device according to claim 1 wherein the second pressure area is arranged between two supporting areas which extend both laterally away from the second pressure area and upwardly.

5. The insertion device according to claim 1 wherein the means for forming the step- or slope-like skin area comprise an adhesive area adapted to be adhered to the skin to be formed.

6. The insertion device according to claim 1 wherein the means for forming the step- or slope-like skin area of the skin comprises at least two holding parts which are movable against each other in order to form the skin.

7. The insertion device according to claim 1 wherein the insertion device is composed of first and second partial bodies wherein the first and second partial bodies are movable against each other and a seam extends between the first and second partial bodies and through the recess.

8. The insertion device according to claim 7 wherein the first and second partial bodies are held to each other by magnetic force.

9. The insertion device according to claim 7 wherein the seam extends in the longitudinal direction of the insertion device.

10. The insertion device according to claim 1 wherein the insertion needle is held in the insertion device at a slanted angle from the top down.

11. The insertion device according to claim 1 wherein at least one of the two pressure areas is a strip having a longitudinal direction which extends in the direction of the insertion needle.

12. The insertion device according to claim 1 wherein at least the second pressure area is a strip.

13. The insertion device according to claim 1 wherein the two pressure areas form a strip-shaped area with which the insertion device acts on the skin of a patient when the insertion device is pressed onto the skin.

14. The insertion device according to claim 2 wherein the strip has a width of less than 1 cm.

15. The insertion device according to claim 2 wherein the second pressure area is arranged between two supporting areas which extend both laterally away from the second pressure area and upwardly.

16. The insertion device according to claim 3 wherein the second pressure area is arranged between two supporting areas which extend both laterally away from the second pressure area and upwardly.

17. The insertion device according to claim 2 wherein the means for forming the step- or slope-like skin area comprise an adhesive area adapted to be adhered to the skin to be formed.

18. The insertion device according to claim 3 wherein the means for forming the step- or slope-like skin area comprise an adhesive area adapted to be adhered to the skin to be formed.

19. The insertion device according to claim 4 wherein the means for forming the step- or slope-like skin area comprise an adhesive area adapted to be adhered to the skin to be formed.

20. The insertion device according to claim 2 wherein the means for forming the step- or slope-like skin area of the skin comprises at least two holding parts which are movable against each other in order to form the skin.
