Abstract

Fluid delivery and measurement systems and methods are disclosed.

Claims

1. A fluid delivery device, comprising:

a housing;

a fluid reservoir within the housing and having a pierceable member;

a needle having a first end and a second end and at least one bend between the first end and the second end;

an initial position defined by the first end being fluidly disengaged from the fluid reservoir and the second end being shrouded by the housing; and

an engaged position defined by the first end extending through the pierceable member and into the fluid reservoir and the second end extending out of the housing,

wherein the needle is configured to translate relative to the housing between the initial position and the engaged position, and

wherein the housing is configured to move about at least a portion of the needle while in the engaged position.

2. The fluid delivery device of claim 1, wherein the needle includes a first end portion proximate the first end and a second end portion proximate the second end and a middle portion extending between and generally perpendicular to the first end portion and the second end portion, the first end portion being generally parallel to the second end portion and the first end portion having a length that is smaller than a length of the second end portion.

3. The fluid delivery device of claim 2, wherein housing is configured to rotate about the at least a portion of the needle while in the engaged position, and wherein the portion of the needle the housing rotates about while in the engaged position is the first end portion.

4. The fluid delivery device of claim 3, wherein the housing is configured to further rotate about the second end portion of the needle while in the engaged position.

5. The fluid delivery device of claim 2, wherein the portion of the needle the housing rotates about while in the engaged position is the second end portion.

6. The fluid delivery device of claim 1, wherein the first and second ends of the needle are configured to be entirely shrouded by the housing and disengaged from the fluid reservoir in the initial position and fluidly coupled with the fluid reservoir and extending from the housing respectively when in the engaged position.

7. The fluid delivery device of claim 1, wherein the pierceable member is generally parallel to a bottom surface of the housing from which the needle extends while in the engaged position.

8. The fluid delivery device of claim 1, wherein the needle is a microneedle.

9. The fluid delivery device of claim 1, wherein the first and second ends of the needle are beveled.

10. The fluid delivery device of claim 1, wherein the pierceable member comprises a septum.

11. The fluid delivery device of claim 1, wherein the housing is configured to be adhered to a skin surface in the engaged position.

12. The fluid delivery device of claim 1, wherein the first end of the needle is configured to pierce the pierceable member in a direction substantially equal to a direction the second end of the needle extends out of the housing while in the engaged position.

13. The fluid delivery device of claim 1, wherein the housing is configured to rotate about first and second portions of the needle while in the engaged position.

14. The fluid delivery device of claim 1 further comprising:

a needle button coupling the needle and the housing.

15. The fluid delivery device of claim 1, wherein the at least one bend is approximately 90 degrees.

16. A fluid delivery device, comprising:

a housing;

a fluid reservoir within the housing and having a pierceable member; and

a needle including first and second ends, a first end portion, a second end portion and a middle portion, the middle portion extending between the first end portion and the second end portion, the first end portion being generally parallel to the second end portion, the first end portion having a length that is smaller than a length of the second end portion, and the first end of the needle and a second end of the needle pointing in a substantially common direction

an initial position defined by the first end being fluidly disengaged from the fluid reservoir and the second end being shrouded by the housing; and

an engaged position defined by the first end extending through the pierceable member and into the fluid reservoir and the second end extending out of the housing,

wherein the housing is configured to move about at least a portion of the needle while in the engaged position.

17. The fluid delivery device of claim 16 further comprising:

a needle button coupling the needle and the housing.

18. The fluid delivery device of claim 17, wherein the middle portion of the needle is coupled to the needle button and the second end portion of the needle is spaced from the housing and the needle button.

19. The fluid delivery device of claim 17, wherein the needle button extends over an entire length of the middle portion of the needle.
