Embodiment Construction

[0064] The present invention relates to a connector for connecting a medical injection device having a barrel and a needle extending from the distal end of the barrel to a container comprising a pierceable septum. Such a connector is configured to be connected to said medical injection device, which is preferably pre-filled with medical components, known as a pre-filled injection device. The assembly formed by connecting the connector to the syringe is stored prior to use, ie before the components contained in the syringe are injected into the vial. The component contained in the barrel is preferably a diluent for the lyophilized or powdered drug.

[0065] A general diagram of an embodiment of assembly 1 is at Figure 1A and 1B shown in .

[0066] According to this embodiment, the connector 2 comprises a deformable inner cover 10 and a rigid outer cover 30 surrounding the deformable inner cover.

[0067] The deformable inner covering 10 extends along a covering axis A from ...

Abstract

The present invention relates to a connector(2) for connecting a medical injection device (60) comprising a barrel (61) and a needle (63) extending from a distal tip (64) of the barrel, to a container(70)comprising a pierceable septum (72), said connector (2) comprising: -an inner deformable cover (10) extending along a cover axis (A)comprising a proximal connection part(13) configured to engagethe distal tip (62) of the barrel, and a distal portion (14) pierceable by the needle, -an outer rigid cover(30) enclosing the inner deformable cover (10) and comprising a distal adaptor (35)configured to engage the container, said outer cover (30) being configured such that the needle tip (64) extends into the distal adaptor (35) when the proximal connection part (13) of the inner deformable cover (10) engages the distal tip (62) of the barrel,the outer rigid cover (30) being fixed to the inner deformable cover (10), wherein the inner deformable cover(10)is compressible along the cover axis(A) between: -a relaxed configuration wherein the distal portion (14) of the inner deformable cover (10) covers the needle tip (63), -a compressed configuration wherein the distal portion (14) is pierced by the needle (63), the needle tip (44) extending distally out of said distal portion (14).

Description

technical field [0001] The invention relates to a connector for connecting a medical injection device to a container. The invention also relates to an assembly comprising a connector and an injection device connected to each other and a method of filling the injection device with components contained in the container by connecting the injection device to the container via the connector. Background technique [0002] In the field of pharmaceutical packaging it is known to store the contents of pharmaceuticals in the form of eg lyophilized pharmaceuticals, powdered pharmaceuticals or pharmaceutical actives in medical containers commonly referred to as "vials". Vials are usually made of glass and sealed with an elastomeric septum crimped by an aluminum cap. A portion of the elastomer in the center of the septum is covered by a plastic or aluminum piece that can be removed by a healthcare professional prior to the reconstitution procedure so that the healthcare professional can...
