Abstract

A blood sampling cartridge is attachable to and removable from an attaching part of a blood test apparatus that includes a housing. The attaching part is provided in one side of the housing. The blood sampling cartridge includes a holder, a blood sensor that is attachable to one end of the holder, a lancet that is movable inside the holder, a blood collection needle attached to one end of the lancet, and a guide provided on the lancet. The guide of the lancet is configured to latch with the holder after puncturing with the blood collection needle, such that the blood collection needle is prevented from projecting beyond the blood sensor.

Claims

1. A blood sampling cartridge that is attachable to and removable from an attaching part of a blood test apparatus having a housing, the attaching part being provided in one side of the housing, the blood sampling cartridge comprising:

a holder;

a blood sensor that is attachable to one end of the holder;

a lancet that is movable inside the holder;

a blood collection needle attached to one end of the lancet; and

a guide provided on the lancet,

wherein the guide of the lancet is configured to latch with the holder after puncturing with the blood collection needle, such that the blood collection needle is prevented from projecting beyond the blood sensor.

2. The blood sampling cartridge according to claim 1, wherein:

the holder has a hole,

the guide is provided on a side surface of the lancet, and

the guide is configured to latch with the hole of the holder.

3. The blood sampling cartridge according to claim 1, wherein:

the holder has a cylindrical shape, and has a plurality of holes in an outer surface of the holder,

the lancet has a rod shape,

the guide of the lancet comprises a plurality of guides provided on an outer surface of the lancet,

the plurality of guides are configured to latch with the plurality of holes, respectively.

4. The blood sampling cartridge according to claim 3, wherein the plurality of guides face each other.

5. The blood sampling cartridge according to claim 1, wherein:

the holder has a convex part,

the guide is provided on a side surface of the lancet, and

the guide is configured to latch with the convex part of the holder.

6. The blood sampling cartridge according to claim 1, wherein:

the blood collection needle is accommodated inside the holder above the blood sensor, and

the blood collection needle is configured to vertically pass through a surface of the blood sensor upon puncturing.

7. The blood sampling cartridge according to claim 1, wherein:

a front part of the holder of the blood sampling cartridge, with respect to an insertion direction of the attaching part, is thinner than a rear part of the holder.

8. The blood sampling cartridge according to claim 1, wherein:

the blood collection needle and the lancet of the blood sampling cartridge are integrated.

9. The blood sampling cartridge according to claim 1, wherein:

the blood sampling cartridge is dividable into the integrated blood collection needle and lancet, and the holder to which the blood sensor is attached.

10. The blood sampling cartridge according to claim 1, further comprising a second holder that covers a surface of the blood sensor, the surface facing outwardly from the holder,

wherein the second holder includes a circular concave part of 4 to 15 mm in diameter on the surface facing outwardly from the holder.

11. The blood sampling cartridge according to claim 1, further comprising a protective cap which covers the blood collection needle.

12. The blood sampling cartridge according to claim 10, further comprising a protective cap which covers the second holder.
