Abstract

Connection systems for injection devices are disclosed. Also disclosed are injection devices and methods of using the same. A connection system includes a first and second connection assembly and a coupling assembly to secure the same. The first connection assembly connects to a medicament container, and the second connection assembly has a needle movable toward the medicament container. Removable flexible barriers are disposed on the first and second connection assemblies and can be removed once the connection assemblies are coupled together to form an aseptic connection between the two assemblies. The needle can be moved toward the medicament container to pierce a septum on the container to form a fluid communication between the container and the needle.

Claims24

Dependent claims

A connection system for use with an injection device, the connection system comprising:

a first connection assembly, a second connection assembly, and a coupling assembly configured to secure the first and second connection assemblies together,
the first connection assembly comprising:
a first body configured to connect to a medicament container, the first body defining a first opening therethrough configured to be in fluid communication with the medicament container;
a first coupling surface on the first body;
a first seal adjacent to the first coupling surface;
and
a first flexible barrier disposed on the first coupling surface, such that the first opening is closed by the first flexible barrier;
and
the second connection assembly comprising:
a second body configured to receive a needle therein, the second body defining a second opening therethrough;
a second coupling surface on the second body, the second coupling surface being configured to be placed adjacent to the first coupling surface;
a second flexible barrier disposed on the second coupling surface, such that the second opening is closed by the second flexible barrier;
and
a second seal adjacent to the second coupling surface,
wherein, when the first and second connection assemblies are secured together, an insertion axis is defined parallel to the needle and extending through the first and second openings of the first and second connection assemblies,
wherein, when the first and second connection assemblies are secured together, the first and second flexible barriers are configured to be removed, such that the first and second openings fluidly communicate with each other,
wherein the needle is configured to be moved through the second opening and the first opening and into the medicament container, such that the needle is in fluid communication with the medicament container, and
wherein an aseptic connection is formed between the first and second connection assemblies.

15 more elements

A connection system for creating an aseptic connection between a container and a delivery conduit of an injection device, the connection system comprising:

a first connection assembly comprising:
a first engagement body having a first end that includes a first opening and is configured to form a seal with a septum of a container, a second end having a second opening, a first cavity between the first and second openings, and a first engagement surface at the second end of the first engagement body;
and
a first flexible barrier configured to form a seal with the second opening;
and
a second connection assembly comprising:
a second engagement body having a first end that includes a third opening, a second end that includes a fourth opening, a second cavity between the third and fourth openings, and a second engagement surface at the second end of the second engagement body;
and
a needle operably connected to the second engagement body;
and a second flexible barrier configured to form a seal with the fourth opening,
wherein the first engagement surface further comprises a first sealing interface configured to form a seal with a second sealing interface on the second engagement surface, and
wherein the connection system is configured such that the needle is moveable relative to the fourth opening of the second engagement body from a first position where the needle is spaced from the third opening, to a second position where the needle extends through the third opening.
