2. Description of the Related Art Peritoneal dialysis therapy involves injecting a peritoneal dialysate into the peritoneal cavity, retaining the peritoneal dialysate for a certain period of time, and dialyzing blood and lymph circulating through the peritoneum using the peritoneum in the human body as a dialysis membrane. is there. This therapy does not significantly limit the patient's daily life as in the case of artificial dialysis, because the patient himself can easily exchange dialysate,
In recent years, many dialysis patients have adopted this therapy. In particular, NPD (Nightly P
eritoneal Dialysis), NIPD
(Nightly Intermittent Per
itoneal Dialysis, CCPD (Co
ntinous Cyclic Peritonea
l Dialysis is a CAPD therapy (Contin) in which the dialysate is changed by machine control at night while the patient is sleeping at night, and the fluid is manually changed at least four times a day.
uous Ambulatory Peritoneal
In addition, fatigue of patients, high infection rate, and simplification of operation such as Dialysis are reduced, and in recent years, it has been accepted as a better mode.

[0003]

Problems to be solved by the invention (1) However,
The dialysis therapy using an automatic peritoneal dialysis device requires an expensive automatic peritoneal dialysis device and other equipment. In addition, a dedicated circuit used as shown in FIG. It is composed of many members such as a channel opening / closing means (clamp), a cassette for easily mounting various conduits on the device, etc., and is a complicated and expensive one, so that it is a better alternative to CAPD therapy. May not be accepted. (2) Further, since the dedicated circuit is used every day, a large amount of the circuit is discarded as garbage, which is causing a social garbage problem. (3) Furthermore, in the dialysis therapy using an automatic peritoneal dialysis device, the dialysate in the dialysate bag is passed through a heating bag and is heated and kept at an appropriate temperature by a heating heater while injecting into the peritoneal cavity. However, since the heating heater is used for 6 to 8 hours / day, its energy consumption does not become ridiculous.

[0004] Therefore, the present invention can perform peritoneal dialysis therapy using an automatic peritoneal dialysis device at a lower cost, and reduce the amount of dust generated by performing dialysis therapy using an automatic peritoneal dialysis device. It is an object of the present invention to provide a bag for peritoneal dialysis, which is expected to save energy.

[0005]

According to the present invention, there is provided a bag for peritoneal dialysis according to the present invention, wherein the two chambers are arranged in layers in a container in which two chambers are formed by an isolating means, and the first chamber is provided. Is a bag for peritoneal dialysis, characterized in that a dialysate is stored in the second bag and a drainage is stored in the second chamber.

With this configuration, the drainage discharged by the dialysis therapy can be collected in the second chamber of the peritoneal dialysis bag according to the present invention. Eliminates the need for bags. In addition, a bag having two chambers, such as the bag for peritoneal dialysis according to the present invention, can reduce manufacturing costs such as material costs and high heat costs as compared with preparing a dialysate bag and a drainage bag, respectively. . As a result, peritoneal dialysis treatment using an automatic peritoneal dialysis device can be made more inexpensive.

Further, when peritoneal dialysis therapy is performed using a conventional dedicated circuit, the drainage bag occupies half of the total amount of waste, but the peritoneal dialysis bag according to the present invention is used. This eliminates the necessity of a dedicated drainage bag, so that a considerable amount of waste can be reduced.

Further, since the dialysate in the first chamber is heated by the heat of the drainage contained in the second chamber, the time required for heating the dialysate by the heater can be shortened, and energy can be saved. Can also be expected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A peritoneal dialysis bag according to the present invention will be described below with reference to FIG. FIG.
(A), (b) shows a bag for peritoneal dialysis according to the present invention. 2A and 2B, reference numeral 4A denotes a first chamber,
B is the second chamber, 2A is the dialysate outlet, 2B drain outlet, 3
A indicates an upper sheet, 3B indicates a lower sheet, and 3C indicates a divided sheet.

The upper sheet 3A, the lower sheet 3B, and the divided sheet 3C are preferably flexible plastic sheets having a thickness of about 0.1 to 0.4 mm.
Examples include vinyl chloride resin, polyethylene, ethylene-vinyl acetate copolymer, polyester, polybutadiene, polypropylene, polyamide, and ethylene-methacrylate copolymer.

The dialysate outlet 2A is connected to a flexible conduit 21a,
A liquid communication means (not shown) provided at any point in the conduit, a connector 21 connected to one end of the conduit;
b, a cap 21c for protecting the tip of the connector. The other end of the flexible conduit 2a is
A is sandwiched between A and the divided sheet 3C, and is welded to the inside of the bag and in liquid communication. The liquid communicating means is not particularly limited. For example, a hard synthetic resin pipe having a thin portion which is closed at one end and broken at the time of use, made of a hard synthetic resin material, and a through-flow opening is closed by a wall. The corresponding tube can be pierced by a correspondingly formed piercing means, for example a spike.
There may be mentioned a means for closing the liquid flow communication portion by means of a friction closing means such as an elastic stopper.

The drainage inlet 2B comprises a flexible conduit 22a, a connector 22b connected to one end of the conduit, and a cap 22c for protecting the tip of the connector. The other end of the flexible conduit 22a is sandwiched between the lower sheet 3B and the divided sheet 3C, and is welded to the inside of the bag and in liquid communication.

The dialysate outlet 2A and the drainage inlet 2B may be provided at any point in the bag, but are preferably provided relatively adjacent to each other. For example, when the outer shape of the bag is substantially rectangular, it is preferable that both are provided on the same side. This is because when the dialysate line and the drainage line are connected to the dialysate outlet 2A and the drainage inlet 2B, respectively, both lines can be bundled and handled, and the circuit is easy to handle.

Further, a dialysate outlet 2A and a drainage inlet 2B
In order to prevent erroneous connection of each line, the colors of the connectors 21b, 22b connected to one end of each conduit or the caps 21c, 22c protecting the ends of the connectors are made different colors, and It is preferable to use the same color as the connector.

It is preferable that the second chamber of the peritoneal dialysis bag according to the present invention is provided with a port for sampling a part of the drainage. This is because it is necessary to constantly monitor the condition of the patient, for example, by examining the presence or absence of leukocytes from the drainage of peritoneal dialysis to confirm the presence or absence of concurrent peritonitis. The port portion has, for example, a cylindrical body that opens to the inside of the bag and the outside of the bag in the second chamber, and is provided with an elastic stopper that seals the opening outside the bag of the cylindrical body. A connector to which a small sampling bag can be connected may be provided in the external opening.

In the bag for peritoneal dialysis according to the present invention, for example, the dialysate outlet 2A is interposed between the upper sheet 3A and the split sheet 3C, and the drainage inlet 2B is interposed between the lower sheet 3B and the split sheet 3C. The three sheets 3A, 3B, 3C, the dialysate outlet 2A and the drainage inlet 2B are simultaneously subjected to high-frequency, ultrasonic heat welding and the like.

Next, a method of using the bag for peritoneal dialysis according to the present invention will be described with reference to FIGS.

For one NPD, NIPD, and CCPD therapy, four peritoneal dialysis bags 1 according to the present invention, a heating bag 10 filled with a dialysate, and a circuit for automatic peritoneal dialysis are prepared. In some cases, it is necessary to use a dialysate having a concentration different from the dialysate concentration packed in the peritoneal dialysis bag according to the present invention. In this case, the concentration change bag 11 filled with the dialysate is used. Prepare

FIG. 3 shows an automatic peritoneal dialysis circuit used in an automatic peritoneal dialysis apparatus. Reference numeral 5 denotes a peritoneal line, 6 denotes a dialysate line, 7 denotes a drainage line, 8 denotes a heating line, 9 denotes a concentration change line, and 12 denotes a cassette. Each line before use is detachably held by a line holder (not shown) to prevent the line from being twisted or tangled.

First, the cassette 12 is mounted on the cassette mounting portion of the automatic peritoneal dialysis device 13. The cassette 12 switches the flow paths of the above-mentioned five lines, and simply attaches each line to an automatic peritoneal dialysis apparatus. The principle of switching the flow path of the cassette 12 includes, for example, opening and closing means of a pipe that opens only one line and closes another line, by rotating a rotating shaft to operate each interlocking cam, Depending on the position of the cam, only one pusher can be opened from the line and the other line can be closed.

Next, the connector 8a of the heating line 8 is connected to the connector of the heating bag 10 filled with the dialysate, and the heating bag 10 is placed on the heating portion of the heater. While the dialysate in the heating bag 10 is being heated, the connector 2 at one end of the dialysate outlet conduit of the bag 1 for peritoneal dialysis according to the present invention.
1b and the connector 6a of each branch line of the dialysate line 6,
6b, 6c and 6d are connected to the connector 2 at one end of the drain outlet conduit.
2b and connectors 7a and 7 of each branch line of the drainage line
b, 7c and 7d are connected. Further, the communication means in the dialysate outlet pipe 21a is destroyed or the like, so that liquid communication is provided between the pipe and the branch line.

Next, the inside of the automatic peritoneal dialysis circuit is filled with a dialysate to perform priming in the circuit. The priming solution after washing is collected in the second chamber 2B of the bag 1 for peritoneal dialysis. Finally, the connector 5a of the peritoneal line 5 and the connector of the transfer tube are aseptically connected to complete the setting of the automatic peritoneal dialysis circuit, and the treatment is started.

The treatment is performed, for example, three to four cycles in the order of drainage, injection, and storage. However, the treatment cycle, time, and the like are not limited to those described above because they are prescribed as appropriate by the doctor depending on the condition of the patient. The principle of liquid injection and discharge to each line is as follows:
For example, an air cylinder is connected to an opening of a hard plastic chamber in which a diaphragm (diaphragm) is sandwiched between a semicircular upper lid and a lower lid, and the air cylinder is reciprocated as a drive pump and a measuring means, The method is performed by inverting a diaphragm (diaphragm) in a chamber up and down.

First, the drainage liquid is collected in the second bag of the peritoneal dialysis bag 1.
The dialysate collected in the chamber 4B and subsequently heated in the heating bag is injected into the patient's peritoneal cavity. The dialysate injected is
While stored in the patient's abdominal cavity for a predetermined time, the dialysate to be injected next time is heated.

The heating of the dialysate after the second cycle is performed by first heating the effluent (about 36 degrees) collected in the peritoneal dialysis bag according to the present invention through the separation sheet 3C. This is performed by exchanging heat with the accommodated first chamber 4A. After a certain period of time, the dialysate heated by the heat of the drainage is filled from the dialysate line 6 into the heating bag 10 via the heating line 8, and further heated by the heater until the temperature reaches an appropriate level. Heated.

Whether the treatment is completed at the stage of drainage, injection, or storage depends on the patient according to the doctor's prescription, but after a series of treatments, the connector 5a of the peritoneal line 5 is terminated.
After that, the connector of the transfer tube is aseptically dissociated, and a cap for maintaining the sterile condition is attached to the connector of the transfer tube. Finally, the cassette 12 is removed from the apparatus, and the drainage and used circuit, the peritoneal dialysis bag 1 according to the present invention, and other dialysate bags (the heating bag 10 and the concentration changing bag 11) are discarded.

[0027]

As described above, according to the bag for peritoneal dialysis according to the present invention, a drainage bag prepared separately from the conventional dialysate bag is unnecessary, so that the peritoneal dialysis therapy using the automatic peritoneal dialysis apparatus can be performed. It can be cheaper.

Further, according to the bag for peritoneal dialysis according to the present invention, a drainage bag, which conventionally occupies about 1/2 of the total amount of waste, is not required. The amount of garbage that can be emitted can be reduced.

According to the bag for peritoneal dialysis according to the present invention, the dialysate in the first chamber is heated by the heat of the drainage contained in the second chamber. Can be shortened, and energy saving can be expected.
