Abstract

A disinfection cap is provided with a cap main body and a wiping body held by the cap main body. The cap main body includes a cap side locking section that prevents pullout of the cap main body by engagement with a medical connector side locking section. The wiping body includes an impregnation section impregnated with an antiseptic solution and is movable with respect to the cap main body so as to wipe at least the surface of a top face wall, the inner peripheral face of an opening of the top face wall, or the surface of a valve body in a male connector connection section of a medical connector with the impregnation section with the cap side locking section engaged with the medical connector side locking section.

First claim

What is claimed is:

1. A disinfection cap for a medical connector, the medical connector including a male connector connection section, in which a valve body blocking an opening of a top face wall is pushed in to form a flow path when a male connector is connected thereto and a medical connector side locking section configured to prevent pullout of the male connector by engagement with a male connector side locking section, the disinfection cap comprising:
a cap main body including a cap side locking section configured to prevent pullout of the cap main body by engagement with the medical connector side locking section; and
a wiping body held by the cap main body, the wiping body including an impregnation section impregnated with an antiseptic solution, a coupling section, and an operation section which is coupled to the impregnation section through the coupling section, the coupling section including an end part forming a small-diameter columnar section which has a smaller diameter than the opening of the top face wall, and a large-diameter columnar section which has a larger diameter than the opening of the top face wall and is continuous with an upper end of the small-diameter columnar section,
wherein the wiping body is movable with respect to the cap main body so as to wipe at least a surface of the top face wall, an inner peripheral face of the opening, or a surface of the valve body in the male connector connection section with the impregnation section with the cap side locking section engaged with the medical connector side locking section; and
wherein the wiping body is movable along an axis of the male connector connection section with respect to the cap main body with the cap side locking section engaged with the medical connector side locking section.

2. The disinfection cap according to claim 1 , wherein the wiping body is rotatable around an axis of the male connector connection section with respect to the cap main body with the cap side locking section engaged with the medical connector side locking section.

3. The disinfection cap according to claim 1 , wherein the wiping body is movable with respect to the cap main body so as to wipe at least the inner peripheral face of the opening with the impregnation section with the cap side locking section engaged with the medical connector side locking section.

4. The disinfection cap according to claim 1 , wherein the operation section is coupled to the impregnation section through the coupling section that extends through a through hole formed on the cap main body.

5. The disinfection cap according to claim 1 , wherein the cap main body is made of a rigid material.

6. The disinfection cap according to claim 1 , wherein the impregnation section includes an impregnation material.

7. The disinfection cap according to claim 6 , wherein the impregnation material is a sponge.

8. The disinfection cap according to claim 6 , wherein the impregnation material is nonwoven.

9. The disinfection cap according to claim 1 , wherein the impregnation section is attached to an outer peripheral face of the small-diameter columnar section and a surface of the large-diameter columnar section.

10. A disinfection system comprising:
a disinfection cap including a cap main body including a cap side locking section configured to prevent pullout of the cap main body by engagement with a medical connector side locking section and a wiping body held by the cap main body, the wiping body including an impregnation section impregnated with an antiseptic solution; and
a medical connector, the medical connector including a male connector connection section, in which a valve body blocking an opening of a top face wall is pushed in to form a flow path when a male connector is connected thereto, and the medical connector side locking section is configured to prevent pullout of the male connector by engagement with a male connector side locking section;
wherein the wiping body further including a coupling section and an operation section which is coupled to the impregnation section through the coupling section, the coupling section including an end part forming a small-diameter columnar section which has a smaller diameter than the opening of the top face wall, and a large-diameter columnar section which has a larger diameter than the opening of the top face wall and is continuous with the upper end of the small-diameter columnar section;
wherein the wiping body is movable with respect to the cap main body so as to wipe at least a surface of the top face wall, an inner peripheral face of the opening, or a surface of the valve body in the male connector connection section with the impregnation section with the cap side locking section engaged with the medical connector side locking section; and
wherein the wiping body is movable along an axis of the male connector connection section with respect to the cap main body with the cap side locking section engaged with the medical connector side locking section.

11. The disinfection system according to claim 10 , wherein the wiping body is rotatable around an axis of the male connector connection section with respect to the cap main body with the cap side locking section engaged with the medical connector side locking section.

12. The disinfection system according to claim 10 , wherein the wiping body is movable with respect to the cap main body so as to wipe at least the inner peripheral face of the opening with the impregnation section with the cap side locking section engaged with the medical connector side locking section.

13. The disinfection system according to claim 10 , wherein the operation section is coupled to the impregnation section through the coupling section that extends through a through hole formed on the cap main body.

14. The disinfection system according to claim 10 , wherein the medical connector side locking mechanism includes an external thread and the cap side locking section includes an internal thread in the cap main body, the external thread engaging the internal thread to prevent pullout of the cap main body.

15. The disinfection system according to claim 14 , wherein the medical connector comprises a mixed injection plug.

16. The disinfection cap according to claim 10 , wherein the impregnation section is attached to an outer peripheral face of the small-diameter columnar section and a surface of the large-diameter columnar section.
