Abstract

There is provided an adapter for blood sample dispensing which enables change of the presence and absence of a medicine to be mixed in a blood sample or the type of the medicine thereof while suppressing contact of blood with the air, during preparation of an examination sample, and a dispensing kit and a needle kit provided therewith. Dispensing is performed using an adapter 1 for blood sample dispensing which is mounted on a distal portion of a syringe and has a piping structure, in which the adapter has a fitting portion 3 fitted to the distal portion at one end, a nozzle portion 2 at the other end, and a flange portion 4 on an outer circumference surface, and in which the adapter 1 has a medicine 5, to be mixed in the blood sample S, on the inside of the nozzle portion 2.

Claims

1. An adapter for blood sample dispensing which is mounted on a distal portion of a syringe and has a piping structure,

wherein the adapter has a fitting portion fitted to the distal portion at one end, a nozzle portion at the other end, and a flange portion on an outer circumference surface, and

wherein the adapter has a medicine, to be mixed in the blood sample, on the inside of the nozzle portion.

2. The adapter according to claim 1,

wherein the adapter has an inner wall projection portion, which is formed in a spiral shape, on the inner wall surface of the nozzle portion.

3. The adapter according to claim 1,

wherein the medicine is applied to the inner wall of the nozzle portion.

4. The adapter according to claim 1,

wherein a support supporting the medicine is provided inside the nozzle portion.

5. The adapter according to claim 1,

wherein the flange portion has a rolling prevention portion.

6. The adapter according to claim 5,

wherein the rolling prevention portion is a linear outer circumference portion which is provided in the outer circumference of the flange portion.

7. The adapter according to claim 1,

wherein an outer wall projection portion is erected on the outer wall surface of the nozzle portion, and a gap is caused between the flange portion and an opening portion by bringing the outer wall projection portion and a dispensing container into contact with each other when the nozzle portion is inserted into the opening portion which is formed in the dispensing container into which the blood sample is dispensed.

8. The adapter according to claim 7,

wherein, in a cross-sectional view of the nozzle portion, the effective diameter of a distal portion of the nozzle portion, which is an effective diameter of the nozzle portion and a diameter of a minimum circumscribed circle of the nozzle portion and the outer wall projection portion, is a size allowing the distal portion to be inserted into the opening portion.

9. The adapter according to claim 8,

wherein the outer wall projection portion has a tapered shape which tapers.

10. The adapter according to claim 8,

wherein the outer wall projection portion extends in an axial direction of the nozzle portion.

11. The adapter according to claim 10,

wherein the outer wall projection portion has a step portion in which the effective diameter of the nozzle portion changes from a value greater than the inner diameter of the opening portion to a value which allows the adapter to be fitted to the opening portion, toward a distal end.

12. The adapter according to claim 10,

wherein there are three or more outer wall projection portions which are disposed in parallel in a circumferential direction of the nozzle portion.

13. The adapter according to claim 8,

wherein the outer wall projection portion extends in a spiral shape along the circumferential surface of the nozzle portion.

14. The adapter according to claim 8,

wherein, when the inner diameter of the opening portion is set to W, the depth of the opening portion is set to D, the outer diameter of the distal end of the nozzle portion is set to φ

1, and the effective diameter of the nozzle portion in a section, in which a gap caused due to the difference between the inner diameter of the opening portion and the effective diameter of the nozzle portion is formed between the opening portion and the section, out of sections of the nozzle portion and the outer wall projection portion, is set to φ

2, the length L between a distal end of the outer wall projection portion and the distal end of the nozzle portion satisfies the following Formula.

15. The adapter according to claim 7,

wherein the effective diameter of a distal portion of the nozzle portion, which is an effective diameter of the nozzle portion and a diameter of a minimum circumscribed circle of the nozzle portion and the outer wall projection portion, is larger than the inner diameter of the opening portion.

16. The adapter according to claim 1,

wherein the flange portion has a through port or a notch.

17. The adapter according to claim 1,

wherein the length of the nozzle portion is 3 mm to 30 mm.

18. The adapter according to claim 1,

wherein the outer diameter of the flange portion is 8 mm to 30 mm.

19. The adapter according to claim 1,

wherein the volume of an internal space of the nozzle portion is 10 μ

L to 1 mL.

20. The adapter according to claim 1,

wherein the adapter has a specific color corresponding to the type of the medicine.

21. A dispensing kit comprising:

the adapter according to claim 8; and

a dispensing container having an opening portion which is fitted to the outer wall projection portion of the adapter.

22. A needle kit comprising:

the adapter according to claim 1; and

a needle having a needle base which is fitted to the distal portion of the syringe,

wherein the nozzle portion of the adapter also capable of being fitted to the needle base.

23. The needle kit according to claim 22, comprising:

the syringe having the distal portion which is fitted to the fitting portion of the adapter.
