Abstract

The invention relates to a plaster for use in the context of an intramuscular injection, particularly a vaccination, having a patient side and an outer side, comprising: an adhesive layer on the patient side for attaching the plaster to the skin of a patient, an absorbent wound-covering on the patient side in the region of an intended intramuscular injection site, the absorbent wound-covering having received a disinfectant, and an opening on the outer side in the area of the absorbent wound-covering of the patient side for the injection needle.

Claims (35)

1 . A plaster for use in the context of an intramuscular injection having a patient side and an outer side, comprising:

an adhesive layer on the patient side for attaching the plaster to the skin of a patient;

an absorbent wound-covering arranged in the center of the adhesive layer on the patient side in the region of an intended intramuscular injection site, the absorbent wound-covering having received a disinfectant; and

an opening in the adhesive layer on the outer side in the area of the absorbent wound-covering of the patient side sized for the intramuscular injection,

wherein the plaster totally covers the intended injection site and the absorbent wound-covering is visible through the opening,

wherein a diameter of the absorbent wound-covering is less than a diameter of the adhesive layer such that the adhesive layer extends beyond an outer perimeter of the absorbent wound-covering, and

wherein a diameter of the opening on the outer side is smaller than the diameter of the absorbent wound-covering on the patient side.

2 . The plaster according to claim 1 , wherein the opening on the outer side is closed with a membrane which prevents the disinfectant from escaping through the opening and allows piercing with an injection needle.

3 . The plaster according to claim 1 , wherein the opening on the outer side is closed with a cover which can be removed for carrying out the injection.

4 . The plaster according to claim 3 , wherein the cover is designed to close the opening on the outer side again after the injection.

5 . The plaster according to claim 4 , wherein the cover is formed as a flap which is permanently connected to the outer side of the plaster at an edge region.

6 . The plaster according to claim 3 , wherein the cover is at least partially self-adhesive.

7 . The plaster according to claim 1 , wherein the absorbent wound-covering further comprises an anaesthetic agent, an analgesic agent, or both for pre-treatment or post-treatment of the injection site of the intramuscular injection.

8 . The plaster according to claim 1 , wherein the plaster comprises a carrier layer on the patient side, which carrier layer is removed before the plaster is applied to the patient's skin.

9 . A plaster for use in the context of an intramuscular injection having a patient side and an outer side, the plaster comprising:

an adhesive layer on the patient side for attaching the plaster to the skin of a patient;

an absorbent wound-covering arranged in the center of the adhesive layer on the patient side in the region of an intended intramuscular injection site, the absorbent wound-covering having received a disinfectant;

an opening in the adhesive layer on the outer side in the area of the absorbent wound-covering of the patient side for the intramuscular injection, and

a membrane arranged on and closing the opening on the outer side, wherein the membrane prevents the disinfectant from escaping through the opening and allows piercing with an injection needle,

wherein the plaster totally covers the intended injection site and the absorbent wound-covering is visible through the membrane covering the opening, and

wherein a diameter of the absorbent wound-covering is less than a diameter of the adhesive layer such that the adhesive layer extends beyond an outer perimeter of the absorbent wound-covering.

10 . The plaster according to claim 9 , wherein a diameter of the opening on the outer side is smaller than the diameter of the absorbent wound-covering on the patient side.

11 . The plaster according to claim 9 , wherein the absorbent wound-covering further comprises an anaesthetic agent, an analgesic agent, or both for pre-treatment or post-treatment of the injection site of the intramuscular injection.

12 . The plaster according to claim 9 , wherein the adhesive layer on the patient side completely surrounds the intended injection site.

13 . The plaster according to claim 9 , wherein the plaster comprises a carrier layer on the patient side, which carrier layer is removed before the plaster is applied to the patient's skin.

14 . A plaster for use in the context of an intramuscular injection having a patient side and an outer side, comprising:

an adhesive layer on the patient side for attaching the plaster to the skin of a patient;

an absorbent wound-covering arranged in the center of the adhesive layer on the patient side in the region of an intended intramuscular injection site, the absorbent wound-covering having received a disinfectant; and

an opening on the outer side in the area of the absorbent wound-covering of the patient side for the intramuscular injection,

wherein the plaster totally covers the intended injection site and the absorbent wound-covering is visible through the opening, and

wherein the opening on the outer side is closed with a cover which can be removed for carrying out the injection.

15 . The plaster according to claim 14 , wherein the cover is designed to close the opening on the outer side again after the injection.

16 . The plaster according to claim 15 , wherein the cover is formed as a flap which is permanently connected to the outer side of the plaster at an edge region, wherein the cover is at least partially self-adhesive.

17 . The plaster according to claim 14 , wherein the absorbent wound-covering further comprises an anaesthetic and/or analgesic agent for pre-treatment or post-treatment of the injection site of the intramuscular injection.

18 . The plaster according to claim 14 , wherein the adhesive layer on the patient side completely surrounds the intended injection site.
