Abstract

The present invention relates to a blood component detection unit, which comprises: a capsule body having a first surface; a needle array including a plurality of needles, each of the needles have an opening and an inner hollow space, and each of the needles protrudes out of the first surface; a detection chamber disposed inside the capsule body and connected with the inner hollow space; a sensing chip disposed inside the capsule body; and a plurality of sensing elements disposed on the sensing chip.

Claims

1. A blood component sampling equipment, comprising:

a housing, which has an opening on a portion of one of walls of the housing;

a blood component detection device having a plurality of blood component detection units installed on a roll of tape, wherein the roll of tape moves each blood component detection unit toward the opening;

an elastic element, attached in connection with one of the blood component detection units that turns to appear at the opening; and

a channel on an inside of the housing that is constructed for a predetermined shape which accommodates the blood component detection device.

2. The blood component sampling equipment according to claim 1, wherein the blood component detection unit comprises a capsule body having a first surface, a needle array including a plurality of needles, each of the needles having an opening and an inner hollow space, and each of the needles protrudes out of the first surface, a detection chamber disposed inside the capsule body and connecting with the inner hollow space, a sensing chip disposed inside the capsule body, and a plurality of sensing elements disposed on the sensing chip.

3. The blood component sampling equipment according to claim 2, wherein each needle of the needle array is coated with an anesthetic substance.

4. The blood component sampling equipment according to claim 2, wherein the blood component detection unit is in a tablet shape.

5. The blood component sampling equipment according to claim 2, wherein the blood component detection unit is a disposable blood component detection unit.

6. The blood component sampling equipment according to claim 2, wherein the plurality of needles is made of a biocompatible material,

7. The blood component sampling equipment according to claim 2, wherein the capsule body is made of a biocompatible material.

8. The blood component sampling equipment according to claim 2, wherein the plurality of needles is manufactured by an imprinting process.

9. The blood component sampling equipment according to claim 8, wherein a mold for the imprinting process is manufactured by LIGA process.

10. The blood component sampling equipment according to claim 1, wherein a dimension of the opening is defined by a size of the blood component detection unit.

11. The blood component sampling equipment according to 1, wherein the elastic element has a specially designed pattern on a pushing surface of the elastic element for having the tip of the needles located on the periphery of the array needle penetrate the skin of a user deeper than the tip of the needles located on other region of the array needle do.

12. The blood component sampling equipment according to 1, wherein the blood component detection device having a plurality of blood component detection units installed on a roll of tape, and the roll of tape of the blood component detection device moves each blood component detection unit toward the opening in a linear direction.

13. The blood component sampling equipment according to 1, wherein the blood component detection device having a plurality of blood component detection units installed on a roll of tape, and the roll of tape of the blood component detection device moves each blood component detection unit toward the opening in a curvilinear direction.
