Abstract

A system for delivering fluidic media may include a reservoir disposed within a housing, the reservoir having at least one wall bordering an interior volume for containing fluidic media, the wall being made of a material comprising a cyclic olefin copolymer, the wall for substantially preventing light from passing through the material of the wall. Fluidic media contained in the interior volume may be expelled through a fluid conduit.

Claims

1. A system for delivering fluidic media, the system comprising:

a housing;

a reservoir disposed within the housing, the reservoir having at least one wall bordering an interior volume for containing fluidic media, the wall being made of a material comprising a cyclic olefin copolymer, the material of the wall is treated with a treatment that substantially prevents light from passing through the material of the wall;

a plunger head arranged for movement in the interior volume of the reservoir to expel fluidic media from the interior volume of the reservoir; and

a fluid conduit in communication with the interior volume of the reservoir for allowing fluidic media contained in the interior volume to be expelled from the reservoir with movement of the plunger head.

2. The system of claim 1, wherein the fluid conduit comprises a needle.

3. The system of claim 1, wherein the reservoir is removable from the housing.

4. The system of claim 1, the wall comprising at least one layer made of a material that is not a cyclic olefin copolymer.

5. The system of claim 1, wherein the wall is opaque to substantially prevent light from passing through the material of the wall.

6. The system of claim 1, wherein the treatment of the material of the wall is at least one of being frosted, textured, and etched to substantially prevent light from passing through the material of the wall.

7. The system of claim 1, the wall having a light transmission at 400 nm of less than 25%.

8. The system of claim 1, the wall of the reservoir having at least one window for allowing light to pass into the interior volume of the reservoir.

9. The system of claim 8, the reservoir having a circular cross-section circumference, the at least one window having a width dimension corresponding to less than a quarter of the circular cross-section circumference.

10. The system of claim 8, the at least one window having a width dimension corresponding to an angle of less than 90°

relative to a central axis of the reservoir.

11. The system of claim 8, the at least one window for providing a viewing angle into the interior volume of the reservoir of less than 90°

relative to a central axis of the reservoir.

12. The system of claim 8, wherein the at least one window comprises a plurality of windows, each of the plurality of windows offset less than 90°

relative to a central axis of the reservoir from any other window of the plurality of windows.

13. The system of claim 8, wherein the housing is sufficiently transparent for allowing light to pass through the housing and the window in the reservoir into the interior volume of the reservoir.

14. The system of claim 8, the housing having at least one window for allowing light to pass through the at least one window of the housing and the at least one window in the reservoir into the interior volume of the reservoir.

15. The system of claim 14, wherein the at least one window of the housing is adjacent and facing the at least one window of the reservoir.

16. The system of claim 8,

the window having a width dimension extending partially around a central axis of the reservoir, the width dimension between a first width edge and a second width edge;

wherein the first width edge is linearly spaced from the central axis of the reservoir in a first linear dimension, and the second width edge is linearly spaced from the central axis of the reservoir in a second linear dimension; and

wherein the first linear dimension and the second linear dimension are at an angle of less than 90°

relative to each other.

17. The system of claim 1, the system further comprising:

a drive mechanism for forcing fluidic media from the interior volume out the fluid conduit in a case where the interior volume contains fluidic media and the drive mechanism is activated.

20. The system of claim 1, wherein the plunger head is in contact with the wall made of the cyclic olefin copolymer material.

21. The system of claim 2, wherein the needle is for insertion into a human to deliver fluidic media from the interior volume of the reservoir when the fluidic media is expelled from the reservoir with movement of the plunger head.

22. The system of claim 1, wherein the fluidic media is an infusion medium.

24. The system of claim 1, wherein the material of the wall is treated with a surface treatment that causes the material of the wall to prevent passage of light.

25. The system of claim 1, wherein the material of the wall that is treated has a surface that is uncovered.

26. The system of claim 1, wherein the material of the wall has a surface and the treatment comprises a surface treatment that prevents light from passing through the wall.

18. A method of manufacturing a system for delivering fluidic media, the system comprising:

providing a housing;

providing a reservoir having at least one wall bordering an interior volume for containing fluidic media, the wall being made of a material comprising a cyclic olefin copolymer;

treating the material of the wall of the reservoir with a treatment to substantially prevent light from passing through the material of the wall;

disposing the reservoir within the housing;

arranging a plunger head for movement in the interior volume of the reservoir to expel fluidic media from the interior volume of the reservoir; and

providing a fluid conduit in communication with the interior volume for allowing fluidic media contained in the interior volume of the reservoir to be expelled from the reservoir with movement of the plunger head.

19. The method of claim 18, the wall of the reservoir having at least one window for allowing light to pass into the interior volume of the reservoir.

23. The method of claim 18, wherein the treatment being at least one of being frosted, textured, and etched to substantially prevent light from passing through the material of the wall.
