Abstract

An on-body injector system includes a drug container assembly including a container, a seal member, and a sealing interface between the seal member and the container. The container includes an opening and the seal member at least partially covers the opening in the container. A fluid pathway assembly is coupled to the drug container assembly and includes a needle that is movable between a storage position, in which a point of the needle is spaced from the seal member, and a delivery position, in which the point of the needle is disposed at least partially through the seal member. A radiation generator is configured to emit rays of radiation to sterilize and/or disinfect the sealing interface. A barrier is disposed adjacent to the sealing interface and has an opening. At least a portion of the drug container assembly is positioned adjacent to the opening in the barrier.

First claim

What is claimed is:

1. An injector system comprising:
a drug container assembly including a container, a seal member, and a sealing interface between the seal member and the container, the container having an opening and the seal member at least partially covering the opening in the container;
a fluid pathway assembly coupled to the drug container assembly and including a needle, the needle being movable between a storage position, in which a point of the needle is spaced from the seal member, and a delivery position, in which the point of the needle is disposed at least partially through the seal member;
a radiation generator configured to emit rays of radiation;
a wall disposed adjacent to the sealing interface and having an opening, at least a portion of the drug container assembly being positioned adjacent to the opening in the wall; and
wherein the sealing interface is positioned to be sterilized or disinfected by radiation from the radiation generator, and an end of the fluid pathway assembly is connected to the container of the drug container assembly.

2. The injector system of claim 1 , wherein the radiation generator is a photon generator.

3. The injector system of claim 1 , wherein at least a portion of the container and the radiation generator are disposed on opposite sides of the wall.

4. The injector system of claim 3 , wherein the at least a portion of the seal member and the radiation generator are disposed on the same side of the wall.

5. The injector system of claim 1 , wherein the rays of radiation emitted by the radiation generator penetrate the seal member to sterilize or disinfect the sealing interface between the seal member and the container.

6. The injector system of claim 1 , wherein:
the seal member includes a first surface and a second surface located on opposite sides of the seal member;
the first surface of the seal member and a wall of the container define a reservoir; and
in the storage position, the point of the needle is disposed adjacent to the second surface of the seal member with no structure in between the second surface of the seal member and the point of the needle.
