Abstract

A device for administering an injectable product including a casing, an injection mechanism including an injection needle pointing in an insertion direction, and a protective cap for the injection needle wherein, in one embodiment, the administering device includes a removing device for removing the protective cap from the injection needle and, in another embodiment, the administering device includes a needle protecting sleeve shiftable generally in alignment with the casing and generally between a front position, advanced relative to the casing, for protecting the injection needle and to a rear position, retracted relative to the casing, for inserting the injection needle into a tissue. In one embodiment, the needle protecting sleeve is prevented from moving completely into the rear position by a lock when the protective cap is protecting the injection needle.

Claims

1. A device for administering an injectable product, comprising:

a) a casing;

b) an injection means including an injection needle pointing in an insertion direction;

c) a protective cap for covering the injection needle; and

d) a removing device for removing the protective cap from the injection needle.

2. The administering device as set forth in claim 1, wherein the removing device can be moved relative to the casing.

3. The administering device as set forth in claim 1, wherein the removing device is formed by a sleeve shiftable generally along a longitudinal axis of the casing and comprises a latching means which engages the protective cap.

4. The administering device as set forth in claim 1, wherein the latching means is formed by at least one gripping arm which projects generally inwardly, obliquely from the needle protecting sleeve with respect to the insertion direction and engages with a resistor on the protective cap to remove the protective cap.

5. The administering device as set forth in claim 4, wherein the resistor is formed by the rim of the sleeve pointing generally inwardly into the casing.

6. The administering device as set forth in claim 3, wherein the sleeve can be moved in the insertion direction along the longitudinal axis of the casing, manually or by a biasing element to remove the protective cap.

7. A device for administering an injectable product, comprising:

a) a casing;

b) an injection means including an injection needle pointing in an insertion direction;

c) a protective cap which can be placed onto the injection needle; and

d) a needle protecting sleeve which can be shifted along the casing generally between a front position, advanced relative to the casing, in order to protect the injection needle and a rear position, retracted relative to the casing, when inserting or in order to insert the injection needle into a tissue;

wherein

e) when the protective cap is in place, the needle protecting sleeve is prevented from retracting completely into the rear position by a locking means.

8. The administering device as set forth in claim 7, wherein the locking means is in a locking position when the protective cap is placed onto the injection needle, and the locking means is in an exposing position for the needle protecting sleeve when the protective cap is removed.

9. The administering device as set forth in claim 7, wherein the locking means comprises at least one bendable locking arm arranged within the casing, said at least one bendable arm bent generally toward the needle protecting sleeve by the protective cap.

10. The administering device as set forth in claim 9, wherein the at least one locking arm is bent generally radially outward with respect to a longitudinal axis of the casing by the protective cap and forms a stopper for the needle protecting sleeve when it is retracted.

11. The administering device as set forth in claim 7, wherein the locking means projects from a product container or from a mounting for a product container generally toward the injection needle.

12. The administering device as set forth in claim 7, wherein the needle protecting sleeve comprises a removing device for removing the protective cap from the injection needle.

13. The administering device as set forth in claim 12, wherein the removing device is associated with the casing.
