Abstract

An in-line sterilization system including a caddie sized and shaped to releasably secure a container and a sterilization system for sterilizing the container using pulsed ultraviolet light. The sterilization system includes a first light source and a second light source positioned within an antechamber and forming a sterilization zone between the first and second light sources, each of the first and second light sources configured to transmit pulsed ultraviolet light into the sterilization zone. The sterilization system includes a transport system having a turntable. The perimeter region of the turntable is arranged to support the caddie upon receipt of the caddie within the antechamber and to move the caddie through the sterilization zone. The caddie and at least the perimeter region of the turntable are transparent to the ultraviolet light. Related systems, devices, compositions, and methods of use are provided.

Claims (24)

1. An in-line sterilization system comprising:

a container comprising a reservoir portion defining an internal volume;

a caddie sized and shaped to releasably secure the container; and

a sterilization system comprising:

a first light source and a second light source forming a sterilization zone between the first and second light sources, each of the first and second light sources configured to transmit pulsed ultraviolet light into the sterilization zone; and

a transport system comprising a turntable having a perimeter region configured to support the caddie and move the caddie through the sterilization zone,

wherein the reservoir portion, the caddie, and at least the perimeter region of the turntable are transparent to the ultraviolet light to sterilize the container prior to the internal volume being filled with a pharmaceutical.

2. The system of claim 1 , wherein the ultraviolet light has a wavelength of between 200 nm and 400 nm.

3. The system of claim 1 , further comprising a container-filling isolator, wherein the sterilization system is incorporated in-line and upstream of the container-filling isolator.

4. The system of claim 1 , wherein the first light source is positioned above the turntable and the second light source is positioned below the turntable.

5. The system of claim 1 , wherein the caddie is formed of cyclic olefin co-polymer.

6. The system of claim 1 , wherein the perimeter region of the turntable is formed of fused silica glass.

7. The system of claim 1 , wherein the container is formed of cyclic olefin co-polymer.

8. The system of claim 1 , wherein the reservoir portion of the container comprises a reservoir manifold sealed to a reservoir film, wherein at least one of the reservoir manifold and the reservoir film comprises cyclic olefin co-polymer.

9. The system of claim 1 , wherein the caddie comprises a nest formed in an upper surface of the caddie that is sized and shaped to mate with the reservoir portion of the container.

10. The system of claim 9 , wherein the upper surface of the caddie further comprises a surface feature sized and shaped to mate with a manifold coupled to the reservoir portion.

11. The system of claim 10 , wherein the caddie further comprises a latch configured to articulate relative to the upper surface of the caddie to secure the container within the nest.

12. An in-line sterilization system comprising:

a caddie sized and shaped to releasably secure a container; and

a sterilization system comprising:

an antechamber;

a first light source and a second light source positioned within the antechamber and forming a sterilization zone between the first and second light sources, each of the first and second light sources configured to transmit pulsed ultraviolet light into the sterilization zone; and

a transport system comprising a turntable having a perimeter region, the perimeter region of the turntable arranged to support the caddie upon receipt of the caddie within the antechamber, the turntable configured to move the caddie supported on the perimeter region through the sterilization zone,

wherein the caddie and at least the perimeter region of the turntable are transparent to the ultraviolet light.
