Abstract

A lancing device comprising: a cover section, a part of which is provided with an opening; a main body held on the cover section and configured to be movable in a predetermined direction from the opening relative to the cover section; a lancing unit which is launched in the predetermined direction; and an operating section configured to launch the lancing unit when the operating section is pushed by applying a force in the predetermined direction, wherein the lancing unit is launched when the force is applied to the operating section in the predetermined direction with regulating a movement of the main body in the predetermined direction, and the main body moves, instead of pushing the operating section, by applying the force in the predetermined direction without regulating the movement of the main body in the predetermined direction is disclosed.

Claims

1. A lancing device comprising:

a cover section, a part of which is provided with an opening;

a main body held on the cover section and configured to be movable in a predetermined direction from the opening relative to the cover section;

a lancing unit which is launched in the predetermined direction; and

an operating section configured to launch the lancing unit when the operating section is pushed by applying a force in the predetermined direction,

wherein the lancing unit is launched when the force is applied to the operating section in the predetermined direction with regulating a movement of the main body in the predetermined direction, and

the main body moves, instead of pushing the operating section, by applying the force in the predetermined direction without regulating the movement of the main body in the predetermined direction.

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

a biasing unit for biasing the lancing unit in the predetermined direction; and

a locking unit for locking a bias of the biasing unit, and unlocking a lock in response to an operation of the operating section;

wherein

the locking unit unlocks the bias and the lancing unit is launched to the predetermined direction when the force is applied to the operating section in the predetermined direction with pushing the main body in the opposite direction to the predetermined direction, and

the main body moves relative to the cover section without releasing the lock of the locking unit by applying the force in the predetermined direction without pushing the main body in the opposite direction to the predetermined direction.

3. The lancing device of claim 2, wherein the biasing unit is an elastic body.

4. The lancing unit of claim 2, wherein the main body is configured return to a first position relative to the cover section after the main body has moved from the first position to a second position relative to the cover section to cause the biasing unit to transition from a non-energized state to an energized state and cause the locking unit to lock the biasing unit and maintain the lock.

5. The lancing device of claim 4, wherein

the locking unit releases the lock and the biasing unit biases the lancing unit in a state where the main body remains at the first position relative to the cover section when the force is applied to the operating section in the predetermined direction with regulating the movement of the main body in the predetermined direction, and

the main body moves from the first position to the second position relative to the cover section without releasing the lock of the locking unit by applying the force in the predetermined direction without regulating the movement of the main body in the predetermined direction.

6. The lancing device of claim 1, configured so that the main body moves in the predetermined direction and the lancing unit is not launched in the predetermined direction by applying the force in the predetermined direction without regulating the movement of the main body in the predetermined direction.

7. The lancing device of claim 1, wherein the main body comprises a guide part for guiding the movement in the predetermined direction relative to the cover section.

8. The lancing device of claim 1, wherein

the cover section is configured to be held by a subject;

and

the operating section is configured to be operated by a hand of the subject which holds the cover section.

9. The lancing device of claim 8, wherein the cover section is cylindrical and provided with an opening at one end.

10. The lancing device of claim 9, wherein the operating section is provided at the other end of the cover section.

11. The lancing unit of claim 1, wherein the lancing unit is a fine needle tip having a plurality of needles.

13. The lancing device of claim 1, configured so that the biasing unit launches the lancing unit in the predetermined direction when the button is pushed in the predetermined direction with the predetermined force while the main body is pressed in an opposite direction to the predetermined direction.

12. A lancing device comprising:

a main body comprising a housing, a biasing unit provided inside the housing and configured to launch a lancing unit in a predetermined direction, and a button for launching the lancing unit via the biasing unit when the button is pushed in the predetermined direction with a predetermined force; and

a cover section to be held by a user when the user pushes the button, and which can hold the main body, with a force that is less than the predetermined force, so that at least part is covered by the housing, wherein

the main body is movable in the predetermined direction relative to the cover section which holds the main body.

14. The lancing device of claim 12 further comprising a locking unit for locking a bias of the biasing unit, and unlocking the lock in response to pushing the button, wherein

the locking unit unlocks the bias and the lancing unit is launched to the predetermined direction when the button is pushed in the predetermined direction with the predetermined force with pushing the main body in the opposite direction to the predetermined direction, and

the main body moves relative to the cover section without releasing the lock of the locking unit when the user applies a force to the button in order to push the button in the predetermined direction without pushing the main body in the opposite direction to the predetermined direction.

15. The lancing device of claim 12, wherein the biasing unit is an elastic body.

16. The lancing unit of claim 14, wherein the main body is configured return to a first position relative to the cover section after the main body has moved from the first position to a second position relative to the cover section to cause the biasing unit to transition from a non-exerting state to an energized state, and cause the locking unit to lock the biasing unit and maintain the lock.

17. The lancing device of claim 12, wherein the main body comprises a guide part for guiding the movement in the predetermined direction relative to the cover section.

18. The lancing device of claim 17, wherein the cover section is cylindrical and provided with an opening at one end.

19. The lancing device of claim 18, wherein the button is provided at the other end of the cover section.

20. The lancing unit of claims 12, wherein the lancing unit is a fine needle tip having a plurality of needles.
