Abstract

The invention relates to an assembly that includes an infusion set and a patch intended for receiving a pump for the transcutaneous administration of a product, said patch including an adhesive portion and a non-adhesive portion, the assembly being characterized in that said set includes patch-guiding elements and sliding elements intended for sliding along the guiding elements.

Claims

1. An assembly adapted to secure a pumping device onto a skin of a patient, the assembly comprising:

an infusion set configured to establish a fluid path between the patient and the pumping device;

a patch for securing the pumping device, the patch includes an upper face configured to removably receive the pumping device, and a lower face having an adhesive portion for adhering to the skin of the patient; and

patch-guiding elements and sliding elements, the sliding elements are configured to slide along the patch-guiding elements such that the patch mechanically couples and slides relative to the infusion set,

wherein the patch-guiding elements and the sliding elements are further configured such that the patch mechanically couples to the infusion set and the patch can be pivoted onto the skin of the patient at a defined position relative to the infusion set, and

wherein the patch-guiding elements comprise tracks and the sliding elements comprise lugs.

2. The assembly according to claim 1 wherein the lower face of the patch further includes a non-adhesive portion.

3. The assembly according to claim 1 wherein said infusion set includes at least one of a flexible cannula, a needle, and a microneedle.

4. The assembly according to claim 1 wherein said infusion set comprises an adhesive portion.

5. The assembly according to claim 1 wherein the patch further includes a non-adhesive portion, the non-adhesive portion of the patch comprises the sliding elements.

6. The assembly according to claim 1 wherein said infusion set comprises stop elements disposed towards one end of the patch-guiding elements and adapted to block a displacement of the sliding elements.

7. The assembly according to claim 1 wherein the sliding elements are disposed towards an edge of the patch.

8. The assembly according to claim 1 wherein the sliding elements are disposed along an axis around which the patch is configured to pivot relative to the infusion set when the sliding elements are found at a stop in the patch-guiding elements.

9. The assembly according to claim 1 wherein when the sliding elements are inserted into the patch-guiding elements, only after the sliding elements are located in a recess defining an end of the patch-guiding elements, the patch is pivotable relative to the infusion set.

10. The assembly according to claim 9 wherein the sliding elements are oriented along a direction that is parallel to a lower surface of the infusion set.

11. The assembly according to claim 1 wherein a cross section of each of said lugs is presented in a form of a rectangle bordered by two half-disks.

12. The assembly according to claim 1 further comprising a lug disposed on each side of a flared portion of the patch.

13. The assembly according to claim 1 wherein the patch-guiding elements are configured to block the patch in a defined position relative to the infusion set.

14. The assembly according to claim 1 wherein an edge of the patch comprises at least two removal zones intended to receive a finger of a user.

15. A utilization of an assembly according to claim 1 comprising the following steps:

placing the infusion set on the skin of the patient,

removing an adhesive film from the patch,

putting the sliding elements in contact with the patch-guiding elements and displacing the patch along a direction that is parallel to a surface of the skin of the patient, and

lowering the patch and putting the patch in contact with the skin of the patient.

16. The assembly according to claim 1, wherein at a first position, the patch-guiding elements and sliding elements are configured to permit a sliding movement of the patch relative to the infusion set, and at a second position, the patch-guiding elements and sliding elements are configured to permit a turning movement of the patch relative to the infusion set, and after engaging in the turning movement a blocking of the sliding movement, to place the patch on a skin of a user by the turning movement.

17. An assembly adapted to secure a pumping device onto a skin of a patient, the assembly comprising:

an infusion set configured to establish a fluid path between the patient and the pumping device;

a patch for securing the pumping device, the patch includes an upper face configured to removably receive the pumping device, and a lower face having an adhesive portion for adhering to the skin of the patient; and

patch-guiding elements and sliding elements, wherein the sliding elements are configured to slide along the patch-guiding elements such that the patch mechanically couples and slides relative to the infusion set,

wherein the patch-guiding elements and the sliding elements are further configured such that the patch mechanically couples to the infusion set and the patch can be pivoted onto the skin of the patient at a defined position relative to the infusion set, and

wherein the patch further includes a non-adhesive portion and the non-adhesive portion includes the sliding elements.

18. An assembly adapted to secure a pumping device onto a skin of a patient, the assembly comprising:

an infusion set configured to establish a fluid path between the patient and the pumping device;

a patch for securing the pumping device, the patch includes an upper face configured to removably receive the pumping device, and a lower face having an adhesive portion for adhering to the skin of the patient; and

patch-guiding elements and sliding elements, wherein the sliding elements are configured to slide along the patch-guiding elements such that the patch mechanically couples and slides relative to the infusion set,

wherein the patch-guiding elements and the sliding elements are further configured such that the patch mechanically couples to the infusion set and the patch can be pivoted onto the skin of the patient at a defined position relative to the infusion set, and

wherein at a first position, the patch-guiding elements and sliding elements are configured to permit a sliding movement of the patch relative to the infusion set, and at a second position, the patch-guiding elements and sliding elements are configured to permit a turning movement of the patch relative to the infusion set, and after engaging in the turning movement a blocking of the sliding movement, to place the patch on a skin of a user by the turning movement.
