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 a longitudinal axis, a first housing end having an opening, a second housing end and an interior space in which the lancet can be received;

a handle having a longitudinal axis, a first handle end and a second handle end, the handle connected to the housing at a location proximate both the second housing end and the second handle end for movement between a storage position where the first housing end is adjacent to the first handle end, the second housing end is adjacent the second handle end and the longitudinal axis of the housing and the longitudinal axis of the handle are parallel, and a use position, wherein the first housing end is located opposite the first handle end, the second housing end is adjacent the second handle end and the longitudinal axis of the housing and the longitudinal axis of the handle are parallel; and

a tray that is receivable within the opening and on which the lancet can be removably retained and that is extendable from the opening such that the lancet can be accessed outside of the housing.

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

a piercing aperture located on the first housing end; and

the first handle end 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,

wherein the first handle end 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, and a third length longer than both the first length and second length when the tray is in an extended 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 the second housing end; 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 at the first handle end that spaces the first leg and the second leg, where the third leg is disposed at the first housing end in the storage position.

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

a structure attached to the tray and 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 at a first end;

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 first piercing aperture through which the sharp tip protrudes during lancing formed through an end wall of the tray, wherein the end wall of the tray substantially occupies the opening of the housing when the tray is in the closed position; and

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 and one width in the storage position and a second length longer than the first length with the one width in the use position.

10. 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.

11. 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.

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

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

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

a structure attached to the end wall of the tray and moveable with respect to the end wall between a first position, where the first piercing aperture is defined, and a second position, where a second piercing aperture through which the sharp tip protrudes is defined, and the second piercing aperture is larger than the first piercing aperture.

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

a housing having an opening at a first end;

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 form a first length, and a use position, where the housing and handle form a second length longer than the first length; and

a structure connected to an end wall of the tray for movement between a first position, where the end wall and the structure cooperate to define a first piercing aperture through which the sharp tip protrudes, and a second position, where the end wall and the structure cooperate to define a second piercing aperture through which the sharp tip protrudes, the second piercing aperture larger than the first piercing aperture.

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

the structure configured for movement to a third position where the structure blocks protrusion of the sharp tip of the lancet through both the first piercing aperture and the second piercing aperture.

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

the structure slidably related to the tray.

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

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