A sealing member 11 is provided at the connecting portion between the tube 4a and the bag 3 so that the bag 3 and the bag 3 can communicate with each other by breaking. In the state where the sealing member 11 is not broken, the bag 3 and the connecting tube 4a communicate with each other. I haven't. The dialysate-filled bag 3 may be any bag that can store the amount of dialysate used for one peritoneal dialysis, and is generally a soft synthetic resin having a certain degree of heat resistance (for example, vinyl chloride resin, Polyolefin, polyolefin such as EVA) is used. The dialysate filled in the dialysate bag 3 may be any one that can be used for peritoneal dialysis.

As described above, the connecting tube 4 is branched into two, and the connectors 7 and 9 are attached to the respective ends. As shown in FIG. 1, the connecting tube 4 is preferably composed of tubes 4a, 4b and 4c and a branch pipe 6 connecting them. And the 1st connector 7 is attached to the front-end | tip of the tube 4b. As the tube 4, a transparent synthetic resin tube having transparency and heat resistance to some extent, such as vinyl chloride resin or silicone rubber, can be preferably used. Further, the tube 4 may be integrally molded without using a branch pipe. Then, the first connector 7 can be connected to the connector member provided on the abdominal catheter or the connector member 30 provided on the extension tube connected to the abdominal catheter. Any connector may be used as the connector 7 as long as it can be connected in a liquid-tight manner. Preferably, a male / female screw type connector that facilitates connection operation is preferable. As a material for forming the connector, a synthetic resin that is lightweight and has sufficient strength to sell hot and cold vinegar is suitable. Further, in order to ensure the aseptic state at the time of connection, it may be formed of a material that can be sterilized with ultraviolet rays or flame.

Then, the sealing member 11 for the bag 3 described above.
Instead of, the tube 4a, that is, a position between the branch portion 6 of the connection tube and the dialysate-filled bag 3) may be provided with a sealing member that allows communication by breaking.

Has one end connected to the waste liquid storage bag 25,
At the other end, a third connector member 9 that can be fluid-tightly connected to the second connector member 9 is provided.
Connector member 21 is provided. As a result, the waste liquid container 20 can be easily separated from the dialysate-filled container 2, and the waste liquid (which is similar to urine) stored in the waste liquid storage bag 25 can be easily discarded and a sample can be collected. be able to. As the second tube 22, a transparent flexible synthetic resin tube such as vinyl chloride resin or silicone rubber can be preferably used. The peritoneal dialysis instrument 1 preferably has a tube opening / closing member 28 for opening / closing the second connection tube 22. When the tube opening / closing member 28 is provided, it is preferable that the tube opening / closing member 28 is attached to a tube to which they are attached in advance, as shown in FIG. It may be attached at the time of use.

The waste liquid storage container 20 is preferably sterilized by a sterilization method that is not heated to a high temperature, such as ethylene oxide gas sterilization, ultraviolet sterilization, and radiation sterilization, instead of high-pressure steam sterilization. This is because the waste liquid storage bag 25 provided in the waste liquid storage container 20 is usually formed into a bag shape with a soft resin, and since the inside is empty, the inner surfaces are in partial contact with each other. When heated to a high temperature by high-pressure steam sterilization in such a state, there is a risk that the contact surfaces will come into close contact and waste liquid cannot be stored inside, but sterilization that is not heated to such a high temperature as described above. If sterilized by the method, there is no such danger. In the present invention, the dialysate filling container 2 described above is used.
Since the waste liquid storage container 20 is separate and is connected at the time of use with these connectors, the dialysis fluid filling container 2 and the waste liquid storage container 20 can be sterilized by different methods. .. In addition, it is not necessary to perform a special treatment on the waste liquid storage container 20 in order to prevent the contact surfaces of the waste liquid storage container 20 from contacting each other during sterilization. Although the forceps may be used as the tube opening / closing member, a clamp that is easy to operate, for example, a one-touch clamp (on-off clamp), a slide clamp, a roller clamp, or the like can be preferably used.

Next, the operation of the peritoneal dialysis instrument of the present invention will be described with reference to FIGS. 2 and 6 using the embodiment shown in FIG. 2 to 6 are explanatory diagrams for explaining the operation. In the initial state, as shown in FIG. 1, the caps 18 and 10 are attached to the connectors 7 and 9 which are the ends of the dialysate-filled container 20 for peritoneal dialysis. Then, the cap 10 is removed, and FIG.
As shown in, the connector 9 and the connector 21 of the waste container 20 are connected. Then, the cap 18 attached to the connector 7 is removed, and the connector 7 is connected to the connector 30 of the extension tube connected to the abdominal catheter. In this state, as shown in FIG. 2, the opening / closing members 24 and 28 are the tubes 4b and 2
2 is sealed, and the dialysate bag 3
The sealing member 11 is not broken. Further, the opening / closing member 32 of the extension tube 42 connected to the abdominal catheter 48
The tube is also sealed. In addition, reference numeral 46 in FIG.

Then, as shown in FIG. 3, the opening / closing member 2
4, 28 and 32 are opened, the waste fluid storage bag 25 is positioned below the human body, and the used dialysate (waste fluid) filled in the abdominal cavity is caused to flow into the waste fluid storage bag 25. By doing this, the connector 7
Even if bacterial contamination occurs during connection between the connector and the connector 30 and during connection between the connector 9 and the connector 21,
Since the used dialysate flowing out from the abdominal cavity cleans the connection parts of these connectors, there is less risk of peritonitis due to bacterial contamination. Then, by this operation 7, the used dialysate can flow out from the abdominal cavity, and a new dialysate can flow into the abdominal cavity.

Subsequently, as shown in FIG. 4, the opening / closing member 28
Is left open, the opening / closing members 24 and 32 are closed, the sealing member 11 of the dialysate bag 3 is broken, and the dialysate bag 3 and the tube 4a are communicated with each other. This allows
The dialysate 8 flows through the tube 4a while pushing the air in the tube 4a, and the air passes through the tube 22 to
It flows into the waste liquid storage bag 25. Then, a small amount of dialysate is caused to flow into the waste liquid storage bag 25. This bleeding is completed in about 3 seconds. Then, as shown in FIG. 5, the opening / closing member 28 is closed again, and the opening / closing member 2 is closed.
4 and 32 are opened. As a result, the dialysate 8 in the dialysate bag 3 flows into the abdominal cavity through the tubes 4a and 4b, the extension tube 42, and the abdominal cavity catheter 48.
Then, after all the dialysate 8 in the dialysate bag 3 has flown into the abdominal cavity, as shown in FIG.
8 and 32 are all closed, the first connector 7 of the peritoneal dialysis instrument 1 is removed from the connector 30 of the extension tube 42, and a cap 3 is attached to the connector 30.
8 is fitted.

Then, in order to discard the waste liquid stored in the waste liquid storage bag 25 of the peritoneal dialysis device 1 separated from the human body, the whole waste liquid is transported to, for example, a toilet, and as shown in FIG. The third connector 21 is detached from the connector 9 and the waste liquid in the waste liquid storage bag 25 is discarded. Therefore, according to this peritoneal dialysis instrument, a cutting means for cutting the tube and its work are not required for discarding the waste liquid, and the waste liquid can be easily discarded. Further, it is possible to easily carry out the analysis of the components in the waste liquid (used dialysate) stored in the waste liquid storage bag, and the sampling for the bacteria test.
