Abstract

Disclosed herein is a device for collecting a sample, which is intended to dispense a received sample onto a measurement strip. The device includes a main body and a pair of receiving pieces. The receiving pieces protrude from a first end of the main body in such a way as to be spaced apart from each other while facing each other, and receive the sample by capillary force acting on a space which is defined between the receiving pieces and which is open on right, left and bottom sides. The device allows the received sample to be easily transferred to a reaction zone of a measurement strip, and enables the sample to be completely absorbed by the reaction zone because of capillary force in a receiving area when the device comes into contact with the reaction zone of the strip.

Claims

1. A device for collecting a sample, comprising:

a main body; and

a pair of receiving pieces protruding from a first end of the main body in such a way as to be spaced apart from each other while facing each other, and receiving the sample by capillary force acting on a space which is defined between the receiving pieces and which is open on right, left and bottom sides, wherein a curvature of each of the receiving pieces is configured such that an end of the receiving piece matches a hole formed in a reaction zone of a measurement strip and is in slight contact with the reaction zone.

2. The device as set forth in claim 1, wherein the first end of the main body protrudes in an arc shape, and the pair of receiving pieces protrudes in an arc shape to correspond to a shape of the first end of the main body.

3. The device as set forth in claim 2, wherein an inner wall of each of the receiving pieces is treated with a surfactant.

4. The device as set forth in claim 2, wherein the receiving pieces protrude by different lengths from the main body, and a difference in protruding length between the receiving pieces is 3 mm or less.

5. The device as set forth in claim 2, wherein a spacing distance between the receiving pieces ranges from 0.20 mm to 2.00 mm.

6. The device as set forth in claim 1, wherein the pair of receiving pieces is formed in a circular shape.

7. The device as set forth in claim 6, wherein an-inner wall of each of the receiving pieces is treated with a surfactant.

8. The device as set forth in claim 6, wherein the receiving pieces protrude by different lengths from the main body, and a difference in protruding length between the receiving pieces is 3 mm or less.

9. The device as set forth in claim 6, wherein a spacing distance between the receiving pieces ranges from 0.20 mm to 2.00 mm.

10. The device as set forth in claim 1, wherein the main body comprises a pair of finger seats which are concavely formed on a second end of the main body to allow a user to easily hold the main body with his or her finger.

11. The device as set forth in claim 1, wherein the sample collecting device is made of an acrylic or hydrophilic plastic material.
