Abstract

A lancet device with an adjustable hypodermic penetration depth according to an exemplary embodiment of the present invention includes: a lancet holder having a lancet seat to mount a lancet at one end; an operating mechanism disposed at the other end of the lancet holder and loading and releasing the lancet holder along a predetermined path; a depth adjusting member receiving the lancet holder and having at least two grooves formed at a predetermined angle on the circumferential surface of one end to form inclined passages clockwise or counterclockwise; and a housing receiving the lancet holder and the operating mechanism and having a protrusion that is formed on the inner side of an end and fitted step by step in the grooves when the depth adjusting member turns at a predetermined angle.

Claims

1. A lancet device with an adjustable hypodermic penetration depth, comprising:

a lancet holder having a lancet seat to mount a lancet at one end;

an operating mechanism disposed at the other end of the lancet holder and loading and releasing the lancet holder along a predetermined path;

a depth adjusting member receiving the lancet holder and having at least two grooves formed at a predetermined angle on the circumferential surface of one end to form inclined passages clockwise or counterclockwise; and

a housing receiving the lancet holder and the operating mechanism and having a protrusion that is formed on the inner side of an end and fitted step by step in the grooves when the depth adjusting member turns at a predetermined angle.

2. The device of claim 1, wherein the housing includes:

a first housing part receiving the operating mechanism; and

a second housing part rotating about the axis of the first housing part, combined with the depth adjusting member therein, and having the protrusion.

3. The device of claim 2, wherein at least two guide protrusions are formed in the same inclining direction as the inclined passage, on the inner side of the second housing part, for guiding combination and rotation between the second housing part and the depth adjusting member, and a rotation guide groove is formed at the depth adjusting member along the movement path of the guide protrusions.

4. The device of claim 2, further comprising a cover hinged to the second housing part and having a through-hole at the center through which a lancet needle of the lancet passes.

5. The device of claim 1, wherein the inclined passages and the grooves are formed symmetrically with a gap of 180 degrees.

6. The device of claim 1, wherein two pieces of the protrusion are formed symmetrically with a gap of 180 degrees and the hypodermic penetration depth of a lancet needle of the lancet is adjusted from 1.7 to 2.0 mm in ten steps.

7. The device of claim 1, wherein a hollow space is defined above the protrusion.

8. The device of claim 1, wherein the inclined passages have a first inclined passage with the inclination decreasing clockwise from 0°

to 180° and

a second inclined passage with the inclination increasing counterclockwise from 0°

to 180°

, and a step having a predetermined height is formed at the joint of the first inclined passage and the second inclined passage,

9. The device of claim 8, wherein ten grooves are formed at each of the first and second inclined passages.
