Abstract

An adaptor for coupling with a medical container having a collar closed by a septum including: a tubular body closed at a distal end with a transversal wall from which extends a hollow spike, and at a proximal end by a pierceable elastomeric piece including a cavity having a plurality of circumferentially distributed chambers, each chamber being connected to the hollow spike by a radial channel, the tubular body further receiving an intermediate piece including a plurality of through holes aligned on the chambers, a selecting member having a closure wall provided with one opening, capable of rotating so that the opening is successively aligned with each of the through holes, and a gripping member for securing the adaptor to the medical container. Also, an assembly including the adaptor and a medical container.

Claims

1. An adaptor for coupling with a medical container having a collar closed by a septum, said septum having an outer surface directed towards an outside of the medical container, the adaptor comprising:

a tubular body substantially closed at a distal end with a transversal wall provided with a central hole from which extends a hollow spike in a distal direction for passage of a fluid, a plurality of circumferentially distributed chambers extending from said transversal wall in a proximal direction, said chambers being closed at a proximal end by a pierceable elastomeric piece, each chamber being connected to said hollow spike by a radial channel provided with a closure member, said closure member being capable of transitioning from a locked state, in which it closes the radial channel, to an open state in which it does not close said radial channel, each chamber being filled with decontaminated air and each closure member being in a locked state in a storage state of said adaptor,

said tubular body further receiving an intermediate piece located proximally with respect to said pierceable elastomeric piece, said intermediate piece comprising a plurality of circumferentially distributed through holes, each through hole being aligned on one chamber of said plurality of chambers,

a selecting member located proximally with respect to said intermediate piece, said selecting member comprising a closure wall provided with one opening, said selecting member being capable of rotating with respect to said intermediate piece, so that said opening is capable of being successively aligned with each of said through holes,

a gripping member for securing the adaptor to the medical container, so that a distal surface of said transversal wall is brought in contact with the outer surface of said septum when said adaptor is secured on said medical container and said hollow spike pierces said septum.

2. The adaptor of claim 1, wherein the pierceable elastomeric piece comprises a flat cylinder provided in the central region of the distal surface with a plurality of flexible distal radial tentacles capable of deflecting proximally, each tentacle facing a radial channel, said tentacle closing said radial channel when in a non-deflected state, and leaving said radial channel open when in a deflected state.

3. The adaptor of claim 1, wherein the gripping member is an axial clipping member capable of being axially mounted on the collar of said medical container.

4. The adaptor of claim 3, wherein the axial clipping member comprises a deflecting skirt capable of being axially engaged on said collar, said deflecting skirt extending from said transversal wall in a distal direction.

5. The adaptor of claim 1, further comprising an indicator system for informing the user about which through hole, out of said plurality of through holes, said opening is aligned with.

6. The adaptor of claim 5, wherein said selecting member comprises a tubular wall receiving a lateral wall of said intermediate piece, the indicator system comprises a window provided on said tubular wall of said selecting member, said window facing different information data located on said lateral wall of said intermediate piece each time said opening is aligned with a new through hole after rotation of the selecting member with respect to said intermediate piece.

7. The adaptor of claim 1, wherein the pierceable elastomeric piece is self-resealing.

8. The adaptor of claim 1, wherein the pierceable elastomeric piece is made of a material selected from synthetic polyisoprene, natural rubber, silicone rubber, thermo-plastic elastomers and combinations thereof.

9. The adaptor of claim 1, further comprising a blister surrounding said adaptor in a storage state.

10. An assembly comprising a medical container having a collar closed by a septum, said septum having an outer surface directed towards an outside of the medical container, and an adaptor according to claim 1.
