Patches for use in conjunction with intramuscular injection, especially vaccination.

Description

[0001] The invention relates to a patch for use in connection with an intramuscular injection, in particular a vaccination, as defined in the claims.

[0002] An intramuscular injection involves injecting a liquid medication into a skeletal muscle. The injection is usually administered into the upper arm (deltoid muscle), thigh (vastus lateralis muscle), or buttocks (gluteus medius or minimus muscle). To perform an intramuscular injection, the intended injection site is first disinfected. The liquid medication is then injected into the skeletal muscle using a needle or syringe, preferably a disposable syringe. After the injection, the injection site is covered with a swab, which is then secured with adhesive tape or a plaster until the injection site has closed.

[0003] Based on this prior art, the invention aims to simplify the administration of an intramuscular injection, particularly its preparation and aftercare, and to reduce the time required. KR 2020 0040329 A discloses a plaster with a patient-side and an outer side, comprising an adhesive layer through which an injection needle can be inserted and a cover, such that the cover can be removed to expose an opening.

[0004] The object of the invention is achieved by a plaster for use in connection with an intramuscular injection, in particular a vaccination, comprising 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 pad on the patient side in the area of ​​an intended injection site of the intramuscular injection, wherein the absorbent wound pad has incorporated a disinfectant, and an opening on the outer side in the area of ​​the absorbent wound pad of the patient side for the injection needle, and wherein the plaster completely covers the intended injection site and the absorbent wound pad is visible through the opening.

[0005] In the context of an intramuscular injection, particularly a vaccination, the patch according to the invention is applied to the patient's skin using the adhesive layer on the patient side to prepare for the injection. The patch is applied to the patient's skin in such a way that the absorbent pad on the patient side is positioned at the intended injection site. Because the absorbent pad contains a disinfectant, the intended injection site is automatically disinfected. The intramuscular injection can then be administered through the opening on the outside of the patch at the intended injection site after the patch has been applied to the patient's skin. Following the intramuscular injection, the injection needle is withdrawn from the injection site.Since the plaster already covers the injection site, no further steps are necessary for aftercare. The plaster can simply be removed once the injection site has closed. The plaster according to the invention thus simplifies the preparation and aftercare of an intramuscular injection, allowing it to be performed more quickly. The plaster according to the invention is particularly suitable for administering intramuscular injections because the injection needle does not need to be inserted precisely into a blood vessel, but only into a larger muscle. The exact injection site is therefore completely covered by the plaster during the intramuscular injection.

[0006] In one embodiment of the invention, the opening on the outside is closed with a membrane that prevents disinfectant from escaping through the opening while allowing the injection needle to penetrate it. This ensures that the intended injection site is disinfected by the disinfectant and that the disinfectant does not escape through the opening on the outside. Simultaneously, the injection needle can be inserted through the membrane. Preferably, the membrane is designed such that it is not damaged by the thin injection needle but reseals itself after the injection. In particular, the membrane is made of silicone.

[0007] According to an alternative embodiment of the invention, the opening on the outside is closed with a cover that can be removed to perform the injection. The cover is advantageously designed to prevent disinfectant from escaping through the opening on the outside. The cover can be removed to perform the intramuscular injection.

[0008] In one advantageous version, the cover is designed to reseal the opening on the outside after injection. This allows the opening on the outside of the patch to be closed after the intramuscular injection, preventing leakage of disinfectant, wound fluid, or blood. Furthermore, this provides better protection for the injection site from external influences.

[0009] In a preferred embodiment of the invention, the cover is designed as a flap which is permanently attached to the outer surface of the patch at one edge. The flap is thus permanently attached to the outer surface of the patch and cannot be dislodged, damaged, soiled, or otherwise affected during the intramuscular injection. If the flap were not permanently attached to the outer surface of the patch, it would have to be temporarily stored in a safe and clean location during the intramuscular injection.

[0010] According to one embodiment of the invention, the cover is at least partially self-adhesive. This allows the cover to be repeatedly attached to the outside of the patch, for example, to close the opening on the outside of the patch before and after intramuscular injection. The outside of the patch can also include an additional coating or the like in the area where the cover is attached, which simplifies attaching and detaching the cover from the outside of the patch.

[0011] According to a particularly advantageous embodiment of the invention, the absorbent wound dressing on the patient's side is arranged on the cover in the area of ​​the opening on the outer surface. The absorbent wound dressing is thus removed along with the cover in the area of ​​the opening on the outer surface to perform the intramuscular injection. The injection needle is inserted directly into the patient's skin without having to penetrate the absorbent wound dressing. This prevents particles of the wound dressing from adhering to the injection needle during insertion. After the intramuscular injection, the opening is preferably closed again with the cover, and the injection site is accordingly covered by the absorbent wound dressing.

[0012] In a further advantageous embodiment of the invention, the absorbent wound dressing also comprises an anesthetic and / or analgesic agent for pretreatment or posttreatment of the injection site for intramuscular injection. This makes the administration of the intramuscular injection as painless as possible for the patient. It is also conceivable that different absorbent wound dressings containing different substances are used for pretreatment and posttreatment, for example, a disinfectant and anesthetic for pretreatment and a disinfectant and analgesic for posttreatment. Other combinations of substances and active ingredients are also conceivable.

[0013] According to one embodiment of the invention, the adhesive layer on the patient side completely surrounds the puncture site. For example, the adhesive layer is arranged around the entire perimeter on the patient side, while the absorbent wound dressing for the intended puncture site is located in the center. The intended puncture site is thus protected from external influences on all sides, and no disinfectant from the absorbent wound dressing can leak out over the perimeter.

[0014] According to one embodiment of the invention, the plaster on the patient side comprises a backing layer, which is removed before the plaster is applied to the patient's skin. Such backing layers are known from wound dressings and protect the adhesive layer and wound pad on the patient side before the plaster is applied to the patient's skin. This backing layer is typically made of two parts, with one part of the backing layer being removed first and the plaster being applied to the patient's skin in the area of ​​the removed backing layer. The second, unremoved part of the backing layer can then be used for handling without touching the underlying adhesive layer. Subsequently, the second part of the backing layer is removed and the plaster is fully applied to the patient's skin.

[0015] Preferably, the carrier layer is designed to be liquid-tight, so that no liquid can reach the adhesive layer or the absorbent wound dressing and the disinfectant from the absorbent wound dressing cannot leak out.

[0016] In a suitable embodiment of the invention, the paving stone has a round, oval, square, rectangular or polygonal shape.

[0017] The absorbent wound pad is preferably positioned centrally on the patient-side of the plaster. This allows the plaster, and in particular the absorbent wound pad, to be placed more precisely at the intended injection site.

[0018] According to an advantageous embodiment of the invention, the plaster is packaged in an outer packaging to protect it from external influences before use. This is also known, for example, from wound plasters.

[0019] Preferably, the plaster according to the invention is designed to be breathable, so that the skin under the plaster can breathe. This accelerates the closure of the puncture site.

[0020] Ideally, the wound dressing is designed in such a way that it does not adhere to the wound at the injection site. This design is also known, for example, from adhesive bandages.

[0021] The invention will now be explained in more detail with reference to exemplary embodiments shown in the figures. The figures show: Fig. 1 a view of the patient side of a first embodiment of a plaster according to the invention, Fig. 2 a view of the outside of the first embodiment of the plaster according to the invention.
