Abstract

The invention provides a needle protector assemblage which contributes to ensuring the safety of a sequence of operations of sucking up fluid through a needle, protecting the needle through which the fluid has been drawn, injecting the fluid into a patient, and housing the needle after injection and also provides the needle protector assemblage including a needle hub (11) of a needle (10), a protector (32) capable of covering the needle (10), and a fixing member (31) which is formed as a continuity of the protector (32) and fixes the needle protector assemblage on the outer perimeter of the needle hub (11) of the needle (10). In this needle protector assemblage, the needle hub (11) includes an outer-perimeter-engaging portion (11b) capable of engaging with the fixing member (31) and an idling portion (11d) capable of idling the fixing member (31).

Claims

1. A needle protector assemblage comprising:

a needle hub (11) of a needle (10);

a protector (32) capable of covering the needle (10); and

a fixing member (31) which is formed as a continuity of the protector (32) and which is fixed to the outer perimeter of the needle hub (11) of the needle (10);

wherein the needle hub (11) comprises;

an outer-perimeter-engaging portion (11b) capable of engaging by friction with the fixing member (31); and

an idling portion (11d) capable of idling the fixing member (31).

2. The needle protector assemblage according to claim 1, wherein one of the outer-perimeter-engaging portion and the idling portion of the needle hub is formed at the near side to the needle and the other at the far side from the needle.

3. The needle protector assemblage according to claim 1, wherein the needle hub further includes a stopper portion for preventing the fixing member from slipping off from the idling portion toward the needle.

4. The needle protector assemblage according to claim 2, wherein the needle hub further includes a stopper portion for preventing the fixing member from slipping off from the idling portion toward the needle.

5. The needle protector assemblage according to claim 1, wherein the inner perimeter of the fixing member includes an engaging portion which engages with the outer perimeter shape of the outer-perimeter-engaging portion of the needle hub.

6. The needle protector assemblage according to claim 2, wherein the inner perimeter of the fixing member includes an engaging portion which engages with the outer perimeter shape of the outer-perimeter-engaging portion of the needle hub.

7. The needle protector assemblage according to claim 3, wherein the inner perimeter of the fixing member includes an engaging portion which engages with the outer perimeter shape of the outer-perimeter-engaging portion of the needle hub.

8. The needle protector assemblage according to claim 4, wherein the inner perimeter of the fixing member includes an engaging portion which engages with the outer perimeter shape of the outer-perimeter-engaging portion of the needle hub.

9. A syringe equipped with the needle protector assemblage according to claim 1, comprising:

a piston which enables the discharge and suction of fluid;

a barrel portion for containing the fluid; and

a tip portion, where the needle protector assemblage is equipped, provided at the tip of the barrel portion.

10. A syringe equipped with the needle protector assemblage according to claim 2, comprising:

a piston which enables the discharge and suction of fluid;

a barrel portion for containing the fluid; and

a tip portion, where the needle protector assemblage is equipped, provided at the tip of the barrel portion.

11. A syringe equipped with the needle protector assemblage according to claim 3, comprising:

a piston which enables the discharge and suction of fluid;

a barrel portion for containing the fluid; and

a tip portion, where the needle protector assemblage is equipped, provided at the tip of the barrel portion.

12. A syringe equipped with the needle protector assemblage according to claim 4, comprising:

a piston which enables the discharge and suction of fluid;

a barrel portion for containing the fluid; and

a tip portion, where the needle protector assemblage is equipped, provided at the tip of the barrel portion.

13. A syringe equipped with the needle protector assemblage according to claim 5, comprising:

a piston which enables the discharge and suction of fluid;

a barrel portion for containing the fluid; and

a tip portion, where the needle protector assemblage is equipped, provided at the tip of the barrel portion.

14. A syringe equipped with the needle protector assemblage according to claim 6, comprising:

a piston which enables the discharge and suction of fluid;

a barrel portion for containing the fluid; and

a tip portion, where the needle protector assemblage is equipped, provided at the tip of the barrel portion.

15. A syringe equipped with the needle protector assemblage according to claim 7, comprising:

a piston which enables the discharge and suction of fluid;

a barrel portion for containing the fluid; and

a tip portion, where the needle protector assemblage is equipped, provided at the tip of the barrel portion.

16. A syringe equipped with the needle protector assemblage according to claim 8, comprising:

a piston which enables the discharge and suction of fluid;

a barrel portion for containing the fluid; and

a tip portion, where the needle protector assemblage is equipped, provided at the tip of the barrel portion.

18. The needle hub according to claim 17, wherein one of the outer-perimeter-engaging portion and the idling portion of the needle hub is formed at the near side to the needle and the other at the far side from the needle.

19. The needle hub according to claim 17, further including a stopper portion for preventing the fixing member from slipping off from the idling portion toward the needle.

20. The needle hub according to claim 18, further including a stopper portion for preventing the fixing member from slipping off from the idling portion toward the needle.

17. A needle hub comprising:

an outer-perimeter-engaging portion (11b) capable of engaging by friction with a needle protector member (30) which comprises a fixing member (31), which is fixed to the outer perimeter of the needle hub (11) of a needle (10); and

an idling portion (11d) capable of idling the fixing member (31).
