Abstract

A lancet holder 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.

Claims

1. A lancet device comprising:

a housing;

a lancet holder mounted to the housing, and comprising;

a holder body having a cavity defining a lancet seat at a first end of the holder body for receiving a lancet needle;

a plurality of elastic fixing portions arranged in pairs to face each other on an inner side of the cavity of the holder body operable to engage the lancet needle so that the lancet needle received in the cavity of the holder body is vertically held, and elastically fixing the lancet needle;

a lancet plate operable to engage the lancet needle, the lancet plate disposed within the cavity of the holder body;

an elastic support member disposed within the cavity of the holder body, under the lancet plate, and configured to compensate for a variable length of the lancet needle; and

a movable shaft coupled to an outer surface of the holder body for releasing and moving the lancet needle.

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

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

a plurality of first fixing members arranged at predetermined angles around the inner side of the cavity of the holder body and adjacent to an open end of the cavity of the holder body; and

a plurality of second fixing members arranged at predetermined angles around the inner side of the cavity of the holder body, wherein the plurality of second fixing members are positioned proximally to the plurality of first fixing members.

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

5. The lancet device claim 1, further comprising a guide wing elongated longitudinally along the outer surface of the holder body and operable to move along a releasing guide groove formed on an inner side of the housing.

6. The lancet device of claim 2, wherein the plurality of elastic fixing portions are plates protruding inward.
