Abstract

A dialysate solution container includes a flexible first bag body. The dialysate solution container further includes a second bag body which has a mixing region for mixing a first powdered pharmaceutical agent and water at a lower end portion of a second interior. The second bag body further has a communication pipe that places the exterior of the second bag body and the second interior in communication, and a first filter which is in communication with a first interior of the first bag body. A first end of the communication pipe is capable of being connected to a dialysis circuit, and a second end thereof is disposed within the mixing region.

First claim

The invention claimed is:

1. A dialysate solution container comprising:
a flexible first bag body, and
a flexible second bag body;
the second bag body comprising:
a first powdered pharmaceutical agent sealed in a second interior of the second bag body;
a communication pipe through which an exterior of the second bag body is in communication with the second interior;
a mixing region at a lower end portion of the second interior for mixing the first powdered pharmaceutical agent with water injected through the communication pipe from the exterior of the second bag body; and
a first filter, disposed at the mixing region, through which the second interior is in communication with a first interior of the first bag body,

wherein a first end of the communication pipe is connectable to a dialysis circuit, and a second end of the communication pipe is disposed in the mixing region.

2. A dialysate solution container comprising:
a flexible first bag body, and
a second bag body, at least a part of which is formed by an inflexible material;
the second bag body comprising:
a first powdered pharmaceutical agent sealed in a second interior of the second bag body;
a communication pipe through which an exterior of the second bag body is in communication with the second interior;
a mixing region at a lower end portion of the second interior for mixing the first powdered pharmaceutical agent with water injected through the communication pipe from the exterior of the second bag body; and
a first filter, disposed at the mixing region, through which the second interior is in communication with a first interior of the first bag body,
wherein a first end of the communication pipe is connectable to a dialysis circuit, and a second end of the communication pipe is disposed in the mixing region.

3. The dialysate solution container as defined in claim 1 , wherein:
the communication pipe included in the second bag body is a single communication pipe included in the dialysate solution container though which water is capable of being injected into the dialysate solution container.

4. The dialysate solution container as defined in claim 1 , wherein:
the second bag body further comprises, at the lower end portion of the second interior, a narrow portion that narrows a space within the second interior such that a lowermost end of the narrow portion is adjacent a maximum outer diameter portion of the first filter.

5. The dialysate solution container as defined in claim 1 , wherein:
the communication pipe is disposed such that a nozzle opening of the second end thereof faces the first filter.

6. The dialysate solution container as defined claim 1 , wherein:
the first filter comprises a top and a three dimensional curved surface which is convex in an upward direction.

7. The dialysate solution container as defined in claim 1 , further comprising:
a flexible third bag body including a second powdered pharmaceutical agent;
the third bag body having a second filter which is in communication with the first bag body, and
the third bag body being disposed such that a third interior of the third bag body is in communication with the second interior of the second bag body through the first filter, and the third interior of the third bag body is in communication with the first interior of the first bag body through the second filter.

8. The dialysate solution container as defined in claim 7 , wherein:
the first bag body surrounds the second bag body and the third bag body.

9. The dialysate solution container as defined in claim 1 , wherein:
the first bag body surrounds the second bag body.

10. The dialysate solution container as defined in claim 1 , wherein:
the second bag body is provided at an exterior of the first bag body; and
the dialysate solution container further comprises a connection pipe having a first end within the first interior of the first bag body and a second end which is in communication with the first filter.

11. The dialysate solution container as defined in claim 2 , wherein:
the communication pipe included in the second bag body is a single communication pipe included in the dialysate solution container though which water is capable of being injected into the dialysate solution container.

12. The dialysate solution container as defined in claim 2 , wherein:
the second bag body further comprises, at the lower end portion of the second interior, a narrow portion that narrows a space within the second interior such that a lowermost end of the narrow portion is adjacent a maximum outer diameter portion of the first filter.

13. The dialysate solution container as defined in claim 2 , wherein:
the communication pipe is disposed such that a nozzle opening of the second end thereof faces the first filter.

14. The dialysate solution container as defined in claim 2 , wherein:
the first filter comprises a top and a three dimensional curved surface which is convex in an upward direction.

15. The dialysate solution container as defined in claim 2 , further comprising:
a flexible third bag body including a second powdered pharmaceutical agent;
the third bag body having a second filter which is in communication with the first bag body, and
the third bag body being disposed such that a third interior of the third bag body is in communication with the second interior of the second bag body through the first filter, and the third interior of the third bag body is in communication with the first interior of the first bag body through the second filter.

16. The dialysate solution container as defined in claim 15 , wherein:
the first bag body surrounds the second bag body and the third bag body.

17. The dialysate solution container as defined in claim 2 , wherein:
the first bag body surrounds the second bag body.

18. The dialysate solution container as defined in claim 2 , wherein:
the second bag body is provided at an exterior of the first bag body; and
the dialysate solution container further comprises a connection pipe having a first end within the first interior of the first bag body and a second end which is in communication with the first filter.

19. The dialysate solution container as defined in claim 1 , wherein:
the first bag body and the second bag body are configured such that solution in which the first powdered pharmaceutical agent is dissolved in the water at the mixing region of the second bag body is introduced into the first interior of the first bag body after passing through the first filter.

20. The dialysate solution container as defined in claim 2 , wherein:
the first bag body and the second bag body are configured such that solution in which the first powdered pharmaceutical agent is dissolved in the water at the mixing region of the second bag body is introduced into the first interior of the first bag body after passing through the first filter.
