Pharmaceutical adaptor system and pharmaceutical kit system
The present invention relates to a pharmaceutical adaptor system. The pharmaceutical adaptor system comprises a syringe assembly having an axial extension and comprising a first end part and a second end part, the first end part having a male tubular projection, the syringe assembly comprising a syringe and a connecting element having a first mechanical connection part, a unit such as a needle, a vial, a catheter or an IV line, and an adaptor providing fluid communication between the syringe and the unit and having a second mechanical connection part configured to engage with the first mechanical connection part in an engagement direction, thereby in fully engaged position preventing further relative axial movement between the adaptor and the male tubular projection, wherein the adaptor comprises a sealing element configured to receive the male tubular projection and provide sealing between the male tubular projection and the adaptor. The present invention also relates to a pharmaceutical kit system comprising a pharmaceutical adaptor system according to the present invention.
1. A pharmaceutical adaptor system comprising:

a unit including at least one of a fluid dispensing element and a fluid storage element, and
an adaptor providing fluid communication between the syringe and the unit and having a second mechanical connection part, the inner surface of the at least a portion of the first mechanical connection part is disposed at least partially within and radially inwardly of at least a portion of the adaptor, the second mechanical connection part being configured to engage with at least a portion of an outer surface of the first mechanical connection part in an engagement direction when in a fully engaged position to at least temporarily prevent relative axial movement between the adaptor and the male tubular projection,
wherein the adaptor comprises a sealing element configured to receive the male tubular projection and provide sealing between the male tubular projection and the adaptor, wherein the sealing element comprises an inner surface configured to engage the outer surface of the male tubular projection, the inner surface of the sealing element facing radially inwardly prior to engaging the outer surface of the male tubular projection.
2. A pharmaceutical adaptor system according to claim 1 , wherein the sealing element is a tubular element having a thickness and a length along the axial extension, said axial extension being larger than the thickness.
3. A pharmaceutical adaptor system according to claim 1 , wherein the sealing element is resiliently configured to provide an axial force opposite the engagement direction upon compression of the sealing element by the male tubular projection.
4. A pharmaceutical adaptor system according to claim 1 , wherein the first mechanical connection part engages with the second mechanical connection part by means of a threaded connection, a snap-lock connection or a bayonet mount connection.
5. A pharmaceutical adaptor system according to claim 1 , wherein the connecting part of the syringe assembly is a syringe cover configured to cover the syringe.
6. A pharmaceutical adaptor system according to claim 1 , wherein the connecting part comprises a first alignment element and the adaptor comprises a second alignment element, indicating a fully engaged/locked state of the pharmaceutical adaptor system when aligned.
7. A pharmaceutical adaptor system according to claim 6 , wherein the alignment elements are integrated in the first mechanical connection part and the second mechanical connection part, respectively.
8. A pharmaceutical adaptor system according to claim 1 , wherein the adaptor comprises a unit connector adapted to connect the adaptor to the unit.
9. A pharmaceutical adaptor system according to claim 1 , wherein the fluid dispensing element is a needle, a catheter or an IV line and the fluid storage element is a vial.
10. A pharmaceutical adaptor system according to claim 1 , wherein the adaptor has a body, the body and the sealing element being injection moulded by two component injection moulding.
11. A pharmaceutical adaptor system according to claim 10 , wherein the body has a bore extending substantially perpendicularly to the axial extension.
12. A pharmaceutical adaptor system according to claim 11 , wherein the sealing element extends into the bore of the body.
13. A pharmaceutical adaptor system according to claim 1 , wherein the sealing element has a varying thickness along the axial extension.
14. A pharmaceutical kit system comprising a pharmaceutical adaptor system according to claim 1 and a second adaptor configured to be connected with the connecting part of the syringe assembly.
15. A pharmaceutical adaptor system according to claim 1 , wherein the at least a portion of the first mechanical connection part comprises a wall at least partially surrounding the at least a portion of the male tubular projection.
16. A pharmaceutical adaptor system according to claim 15 , wherein the wall is an annular wall.
17. A pharmaceutical adaptor system according to claim 1 , wherein at least a portion of the adaptor is disposed radially between the at least a portion of the first mechanical connection part and the at least a portion of the male tubular projection.
18. A pharmaceutical adaptor system according to claim 1 , wherein the at least a portion of the first mechanical connection part and the male tubular projection are not integrally formed as a single, unitary structure.
19. A pharmaceutical adaptor system according to claim 1 , wherein an axial position of the at least a portion of the adaptor corresponds to an axial position of the at least a portion of the connecting part.
20. A pharmaceutical adaptor system according to claim 1 , wherein the adaptor surrounds at least the at least a portion of the connecting part.
21. A pharmaceutical adaptor system according to claim 1 , wherein the at least a portion of the first mechanical connection part is disposed radially between the at least a portion of the adaptor and the at least a portion of male tubular projection.
22. A pharmaceutical adaptor system according to claim 21 , wherein the at least a portion of the first mechanical connection part does not directly contact and is not integrally formed with the male tubular projection.
23. A pharmaceutical adaptor system according to claim 22 , wherein the at least a portion of the first mechanical connection part comprises a radially outwardly directed surface facing a radially inwardly directed surface of the at least a portion of the adaptor.
