Abstract

Provided is a sample collection and separation device comprising a sample collection unit having a sample collection portion that uses capillary action and an analyte storage unit having a housing into which the sample collection unit is inserted, whereby the sample collection unit containing the collected sample is integrated by means of insertion, so as to permit centrifugation and storage or transport of the sample, and the target sample can be recovered following centrifugation.

Claims (21)

1. A blood sample collection and separation device, comprising

a blood sample collection unit having an inside space specifically configured and structured to hold a blood sample and having openings at the top and the bottom, wherein the inside space, the bottom opening and the top opening communicate, the inner diameter thereof increases from the bottom opening toward the top opening, and the wall surface defining the inside space into which the blood sample is placed forms a gradient continuing from the bottom opening toward the top opening,

an analyte storage unit having a housing into which the blood sample collection unit is inserted and having a blood sample collection unit bottom cap tightly sealing the bottom opening of the blood sample collection unit which is specifically configured and structured to hold the blood sample, wherein the blood sample collection unit bottom cap has an agent holding portion for holding an agent, and it is configured that when the blood sample collection unit is inserted into the analyte storage unit and the bottom opening is inserted into the agent holding portion, then, at least a part of the agent enters into the blood sample collection unit, and

an analyte sealing cap for plugging the top opening of the blood sample collection unit, wherein when the analyte sealing cap plugs the top opening under condition of insertion of the blood sample collection unit into the analyte storage unit, the blood sample is sealed.

2. The blood sample collection and separation device according to claim 1 , wherein a lock mechanism is provided in the agent holding portion, and it is configured that when the blood sample collection unit is inserted into the analyte storage unit and the bottom opening is inserted into the agent holding portion, then, the lock mechanism contacts with the end peripheral part of the blood sample collection unit and the blood sample is held sealed under condition of entering of at least a part of the agent into the blood sample collection unit.

3. The blood sample collection and separation device according to claim 2 , wherein the wall surface is hydrophilized.

4. The blood sample collection and separation device according to claim 3 , wherein an agent is previously placed in the agent holding portion of the analyte storage unit.

5. The blood sample collection and separation device according to claim 4 , wherein the agent is a separating agent.

6. The blood sample collection and separation device according to claim 5 , wherein the blood sample is peripheral blood.

7. The blood sample collection and separation device according to claim 3 , wherein the blood sample is peripheral blood.

8. The blood sample collection and separation device according to claim 4 , wherein the agent is an anticoagulant.

9. The blood sample collection and separation device according to claim 4 , wherein the blood sample is peripheral blood.

10. The blood sample collection and separation device according to claim 2 , wherein the upper part of the agent holding portion is in the form of taper.

11. The blood sample collection and separation device according to claim 2 , wherein the blood sample is peripheral blood.

12. The blood sample collection and separation device according to claim 2 , wherein an agent is previously placed in the agent holding portion of the analyte storage unit.

13. The blood sample collection and separation device according to claim 12 , wherein the agent is a separating agent.

14. The blood sample collection and separation device according to claim 12 , wherein the agent is an anticoagulant.

15. The blood sample collection and separation device according to claim 1 , wherein the wall surface is hydrophilized.

16. The blood sample collection and separation device according to claim 15 , wherein the blood sample is peripheral blood.

17. The blood sample collection and separation device according to claim 15 , wherein the blood sample is peripheral blood.

18. The blood sample collection and separation device according to claim 1 , wherein the blood sample is peripheral blood.
