Abstract

The present invention provides a lancet holder that can smoothly and accurately hold all of lancets with different cross-sections and diameters and can keep them vertical, and a lancet device including the lancet holder.

To this end, a lancet holder according to an exemplary embodiment of the present invention includes a holder body having a lancet seat at one end to mount a lancet and receiving the lancet and elastic fixing portions arranged in pairs to face each other on the inner side of the holder body so that the lancet received in the holder body is vertically held, and elastically fixing the lancet.

According to this configuration, the lancet holder can accurately keep all of lancets vertical, even if the lancets are different in cross-section and diameter, such that the lancet can be mounted on the lancet holder and protrude at a predetermined length in releasing and the lancet needle can vertically protrude through the through-hole of the cover and damage only a predetermined target portion of a subject.

Claims

1. A lancet holder comprising:

a holder body having a lancet seat at one end to mount a lancet and receiving the lancet; and

elastic fixing portions arranged in pairs to face each other on the inner side of the holder body so that the lancet received in the holder body is vertically held, and elastically fixing the lancet.

2. The lancet holder of claim 1, wherein the elastic fixing portions are arranged at predetermined angles around the inner side of the holder body.

3. The lancet holder of claim 2, wherein the elastic fixing portions include:

first fixing members arranged at predetermined angles around the inner side of the upper end of the holder body; and

second fixing members arranged at predetermined angles around the inner side of the lower end of the holder body.

4. The lancet holder of claim 3, wherein the elastic fixing portions are plates protruding inward.

5. The lancet holder of claim 1, further comprising a guide wing elongated longitudinally along the outer side of the holder body and moving along a releasing guide groove formed on the inner side of the housing receiving the holder body.

6. The lancet holder of claim 1, wherein a movable shaft for releasing and moving the lancet is coupled to the underside of the holder body.

7. The lancet holder of claim 1, further comprising:

a lancet plate facing the lower end of the lancet on the bottom of the holder body; and

an elastic support member disposed under the lancet plate and compensating for a variable length of the lancet.

8. A lancet device including the lancet holder of claim 1.

9. A lancet device including the lancet holder of claim 2.

10. A lancet device including the lancet holder of claim 3.

11. A lancet device including the lancet holder of claim 4.

12. A lancet device including the lancet holder of claim 5.

13. A lancet device including the lancet holder of claim 6.

14. A lancet device including the lancet holder of claim 7.
