Abstract

A lancing device for use with a removable lancet having a sharp tip. The lancet includes a housing. The lancing device can include a handle connected to the housing for movement between a storage position, where the housing and handle are configured to be compactly stowed, and a use position, where the housing and handle are configured to be grasped by a user to perform the piercing operation. The lancing device can include an opening formed in the housing and a tray that is moveable with respect to the housing between an open position, where the lancet can be installed on or removed from the tray, and a closed position, where the lancet can be utilized to perform a piercing operation. The lancing device can include a structure moveable with respect to the housing between a first position, where a first piercing aperture is defined, and a second position, where a second piercing aperture is defined, where the second piercing aperture is larger than the first piercing aperture.

Claims

1. A lancing device for use with a removable lancet having a sharp tip, comprising:

a housing having an interior space in which the lancet can be received;

a handle connected to the housing for movement between a storage position, where the housing and the handle are configured to be compactly stowed, and a use position, where the housing and the handle are configured to be grasped by a user to perform a piercing operation.

2. The lancing device of claim 1, further comprising:

a piercing aperture; and

the handle substantially blocks the piercing aperture in the storage position.

3. The lancing device of claim 1, further comprising:

the handle overlies at least part of the housing in the storage position to prevent insertion or removal of the lancet from the interior space.

4. The lancing device of claim 1, further comprising:

the housing having an opening;

a tray that is receivable within the opening and on which the lancet can be removably retained; and

the handle overlies at least part of the opening in the storage position to prevent removal of the tray from the housing.

5. The lancing device of claim 1, further comprising:

the housing and the handle cooperate to define a first length in the storage position and a second length in the use position.

6. The lancing device of claim 1, further comprising:

the handle is pivotally connected to the housing for movement between the storage position and the use position.

7. The lancing device of claim 6, further comprising:

a pivot joint formed at a first end of the housing; and

the handle having a first leg pivotally connected to the housing by the pivot joint, a second leg pivotally connected to the housing by the pivot joint, and a third leg that spaces the first leg and the second leg, where the third leg is disposed at a second end of the housing in the storage position.

8. The lancing device of claim 1, further comprising:

a structure moveable with respect to the housing between a first position, where a first piercing aperture is defined, and a second position, where a second piercing aperture is defined, and the second piercing aperture is larger than the first piercing aperture.

9. A lancing device for use with a removable lancet having a sharp tip, comprising:

a housing having an opening; and

a tray that is receivable within the opening and on which the lancet can be removably retained, the tray moveable with respect to the housing between an open position, where the lancet can be installed on or removed from the tray, and a closed position, where the lancet can be utilized to perform a piercing operation.

10. The lancing device of claim 9, further comprising:

the tray having an end wall; and

a piercing aperture formed through end wall,

wherein the end wall of the tray substantially occupies the opening of the housing when the tray is in the closed position.

11. The lancing device of claim 9, further comprising:

the lancet including a cap configured to cover the sharp tip; and

at least one engaging member that engages the cap of the lancet when the tray is moved from the open position to the closed position, wherein engagement of the engaging member with the cap removes the cap from the sharp tip of the lancet.

12. The lancing device of claim 9, further comprising:

a carrier block that is engageable with the lancet to cover the sharp tip, the carrier block having a first engaging structure configured to allow disengagement of the lancet and the carrier block during installation of the lancet with respect to the lancing device, and a second engaging structure configured to permit engagement of the lancet and the carrier block during removal of the lancet from the lancing device and restrain the lancet against subsequent disengagement from the carrier block; and

an engaging member that is slidably connected to the housing and engageable with the lancet to remove the lancet from the first engaging structure of the carrier block.

13. The lancing device of claim 9, further comprising:

a handle connected to the housing for movement between a storage position and a use position, where the housing and the handle cooperate to define a first length in the storage position and a second length in the use position.

14. The lancing device of claim 13, further comprising:

the handle is pivotally connected to the housing for movement between the storage position and the use position.

15. The lancing device of claim 9, further comprising:

a structure moveable with respect to the housing between a first position, where a first piercing aperture is defined, and a second position, where a second piercing aperture is defined, and the second piercing aperture is larger than the first piercing aperture.

16. A lancing device for use with a removable lancet having a sharp tip, comprising:

a housing having an opening;

a tray that is receivable within the opening and on which the lancet can be removably retained, the tray moveable with respect to the housing between an open position, where the lancet can be installed on or removed from the tray, and a closed position, where the lancet can be utilized to perform a piercing operation;

a handle connected to the housing for movement between a storage position, where the housing and handle are configured to be compactly stowed, and a use position, where the housing and handle are configured to be grasped by a user to perform the piercing operation; and

structure connected to the tray for movement between a first position, where the tray and the structure cooperate to define a first piercing aperture, and a second position, where the tray and the structure cooperate to define a second piercing aperture, the second piercing aperture larger than the first piercing aperture.

17. The lancing device of claim 16, further comprising:

the end portion connected to the tray for movement to a third position where the end portion blocks movement of the sharp tip of the lancet out of the housing.

18. The lancing device of claim 16, further comprising:

the end portion slidably related to the tray.

19. The lancing device of claim 16, further comprising:

the housing and the handle cooperate to define a first length in the storage position and a second length in the use position.

20. The lancing device of claim 16, further comprising:

the handle overlies at least part of the opening in the storage position to prevent removal of the tray from the housing.
