Abstract

Fluid delivery device includes a body, a cannula adapted to extend into subcutaneous tissue, and a septum member adapted to allow a needle to puncture the septum member and to reseal the puncture once the needle is withdrawn from the puncture. The septum member is at least one of; a cap-shaped member, a member having at least two non-parallel walls that can each be punctured by a needle, and a member having a generally planar wall and a generally cylindrical wall which can each be punctured by a needle.

Claims

1. A fluid delivery device comprising:

a body;

at least one cannula adapted to extend into subcutaneous tissue and being arranged to move relative to the body between a retracted or initial position and an extended or puncturing position;

a septum member comprising a puncturable first section and a puncturable second section;

a first internal space that is in fluid communication with the cannula;

a second internal space that is at least one of;

different from the first internal space;

arranged between an upper end of the cannula and the first internal space; and

in fluid communication with the first internal space.

2. The device of claim 1, wherein the body comprises an adhesive layer structured and arranged to at least temporarily secure the device to a user'"'"'s skin.

3. The device of claim 1, further comprising a removable needle insertion mechanism having a portion which extends through the cannula and another portion which can be gripped by a user.

4. The device of claim 1, further comprising a support member comprising a first opening arranged over a one portion of the septum member and at least one second opening arranged over a different portion of the septum member.

5. The device of claim 4, wherein at least one of:

the first opening comprises an axial opening and the at least one second opening comprises a generally circumferential opening or slot;

the first opening comprises an axial opening and the at least one second opening comprises a opening whose center axis is oriented at an angle between an axis of the first opening and a radial plane perpendicular to the axis of the first opening; and

the first opening comprises an axial opening and the at least one second opening comprises at least two equally angularly spaced openings.

6. The device of claim 1, further comprising a needle insertion mechanism configured to cause movement of the cannula.

7. The device of claim 1, further comprising a removable safety device structured and arranged to prevent movement of the cannula.

8. The device of claim 1, further comprising a manually activated needle insertion mechanism configured to cause movement of the cannula.

9. The device of claim 1, further comprising a trigger activated needle insertion mechanism configured to cause movement of the cannula.

10. The device of claim 1, further comprising a needle insertion mechanism configured to automatically cause movement of the cannula.

11. The device of claim 1, further comprising at least one of:

a needle insertion mechanism comprising a biasing mechanism for causing movement of the cannula; and

an arrangement for adjusting a cannula penetrating depth.

12. The device of claim 1, wherein the device is adapted to function with a removable needle insertion mechanism and a tool comprising a biasing mechanism for causing movement of the cannula.

13. The device of claim 1, wherein the device is adapted to function with a removable needle insertion mechanism and a trigger activated tool comprising a biasing mechanism and a movable member for causing movement of the cannula.

14. The device of claim 1, wherein the device is a single-use device.

15. The device of claim 1, wherein the device is a single-use device and usable with an installation tool.

20. A method of making the fluid delivery device of claim 1, the method comprising:

mounting a cannula and a septum to a body.

21. A method of using the fluid delivery device of claim 1, the method comprising:

attaching the device to a user'"'"'s skin; and

inserting a portion of the cannula into the subcutaneous tissue.

16. A fluid delivery device comprising:

a body having a cross-sectional width that is greater than a cross-sectional height;

at least one movable cannula adapted to extend into subcutaneous tissue;

an insertion mechanism adapted to be gripped by a user and adapted to facilitate insertion of the cannula into the subcutaneous tissue;

a septum member adapted to allow a needle to puncture the septum member and to reseal the puncture once the needle is withdrawn from the puncture;

the septum member comprising a one-piece member having a puncturable wall, a puncturable sidewall, and a first internal space that is in fluid communication with the cannula; and

a second internal space is arranged in the body.

17. A fluid delivery device comprising:

at least one cannula adapted to extend into subcutaneous tissue;

a body having an upper end adapted to interface with a device for causing movement of the at least one cannula;

an insertion mechanism adapted to be gripped by a user and comprising a needle portion adapted to facilitate insertion of the cannula into the subcutaneous tissue;

a one-piece septum member adapted to allow a needle to puncture the septum member and to reseal the puncture once the needle is withdrawn from the puncture;

the septum member comprising at least one of;

a member having a puncturable main wall, a puncturable sidewall, and an internal space that is in fluid communication with the cannula;

a cap-shaped member comprising a main puncturable and resealable section, a side puncturable and resealable section, and an internal needle receiving space;

a member having at least two non-parallel walls that can each be punctured by a needle and an internal needle receiving space; and

a member having a generally planar wall, a generally cylindrical wall which can each be punctured by a needle, and an internal needle receiving space; and

another internal space arranged in the body between an upper end of the cannula and the internal space of the septum member.

18. A fluid delivery device comprising:

a body having a surface attachable to a skin surface;

at least one cannula adapted to extend into subcutaneous tissue;

the at least one cannula being movable relative to the body from an initial retracted position to a puncturing position;

a septum member; and

a support having openings allowing a needle to puncture different portions of the septum member,

wherein a surface of the septum member is located over an upper end of the cannula after the cannula is moved to the puncturing position.

19. A fluid delivery device comprising:

a body;

at least one cannula adapted to extend into subcutaneous tissue and being arranged to move relative to the body between a retracted or initial position and an extended or puncturing position;

a septum member comprising a puncturable first section and a puncturable second section;

a first internal space that is in fluid communication with the cannula and that is arranged within the body and disposed between the septum member and the cannula when positioned in the extended or puncturing position;

a second internal space that is at least one of;
