JPH06105907A - Metering bag for peritoneum dialysis - Google Patents

Abstract

PURPOSE:To provide the metering bag for peritoneum dialysis which can easily be handled by two-folding one sheet of resin sheet to produce the metering bag for peritoneum dialysis consisting of a tube for injecting in and out the drained liquid from the inside of the abdominal cavity, a drained liquid housing part and a bag hanger mounting section. CONSTITUTION:The pouch-shaped bag A is formed by two-folding one sheet of the resin sheet and welding or bonding the peripheral edge thereof with a sealing part (a) and is formed with the space drained liquid housing part (b). A part (d) is held open at both ends by the expanding force of the resin sheet itself to form the bag hanger mounting section in the open state. The tube (c) is formed as the injection port of the drained liquid from the inside of the abdominal cavity and the discharge port of the drained liquid filled into the bag and is metered. The tip of the tube (c) is connected with the line-set for the peritoneum dialysis. Since the bag hanger mounting section is held open, a bag hanger can be easily passed into the hanger mounting section and the easy mounting of a line set is possible. The laboriousness at the time of mounting is lessened.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to peritoneal dialysis, particularly continuous ambulatory peritoneal dialysis (CCPD) and intermittent peritoneal dialysis (IPD).
The present invention relates to a measuring bag for peritoneal dialysis, which constitutes one component of the peritoneal dialysis line set used for performing these treatments by being attached to a device for carrying out the above.

2. Description of the Related Art Currently, there is a peritoneal dialysis method such as a hemodialysis method, which is infrequent but gradually increasing, for the treatment of end-stage renal disease. In the peritoneal dialysis method, a dialysate is injected into a patient's abdominal cavity through a tube or a catheter and retained for a sufficient time. During retention, blood impurities are removed from the peritoneum into the dialysate, and after a certain period of time, the impurity-containing dialysate (drainage) is discharged from the infused tube or catheter. In order to carry out such peritoneal dialysis, a peritoneal dialysis device and an appropriate line set attachable thereto are required. A peritoneal dialysis device is a device that controls a fixed amount of dialyzed solution that has been heated and injected into the abdominal cavity and allowed to stay for a certain period of time, then discharge and measure it to remove water and remove blood impurities as prescribed. And the line set is a dialysate line including a metering bag. Most of these peritoneal dialysis treatments are required to be safer, simpler and more convenient in consideration of the fact that the patients themselves handle them at home, and each dialysis manufacturer is currently searching for them.

[0003]

The impurity-containing dialysate discharged from the abdominal cavity needs to be accurately measured in order to safely perform peritoneal dialysis treatment as prescribed. Therefore, a certain amount of the dialysate containing impurities is stored in the peritoneal dialysis measuring bag and measured. The measuring bag is usually used by being suspended through a bag hanger of a peritoneal dialysis device. However, the peritoneal dialysis mainly needs to be performed daily at home by the patient, and therefore, the line set including the measuring bag must be attached to the peritoneal dialysis device by the patient, which is more simplified and easier to use. Good things are needed.

[0004]

[Means for Solving the Problems] Therefore, the inventors of the present invention have made earnest studies for the purpose of obtaining a more simplified and easy-to-use peritoneal dialysis weighing bag, and as a result, devised a method for manufacturing the weighing bag to improve the usability. The present invention has been accomplished by finding that a good measuring bag can be provided.

That is, according to the present invention, there is provided a peritoneal dialysis measuring bag for storing drainage from the abdominal cavity and measuring the drainage. In order to have a bag hanger attachment part for attaching to the peritoneal dialysis device through the bag hanger, and the measurement bag for peritoneal dialysis is made by folding one resin sheet in two, the bag hanger attachment part is Provided is a peritoneal dialysis measuring bag characterized by being in an open state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The measuring bag for peritoneal dialysis of the present invention will be described below in detail with reference to the preferred embodiments shown in the accompanying drawings. 1 and 2 are views showing an embodiment of a measuring bag for peritoneal dialysis according to the present invention at different angles. The bag A is a bag-shaped bag as shown in the figure. For example, one resin sheet is folded in two and a seal portion a (FIGS.
In FIG. 5, the shaded portions in FIG. 2) are welded (by heat or high frequency) or adhered. An inner space drainage storage portion b surrounded by the seal portion a is formed. A single resin sheet is folded in two, leaving a slightly bent tip portion (portion indicated by d in FIGS. 1 and 2), and a sealing portion a shown by hatching in FIGS.
The bag A of the present invention is manufactured by welding or adhering at this point. Thus, the portion indicated by d in FIGS. 1 and 2 is in an open state at both ends as shown in d of FIG. 2 due to the extension force of the resin sheet itself, and the bag hanger in the opened state characterized by the present invention. A mounting site is formed.

In a conventional measuring bag, usually two resin sheets are superposed on each other and, for example, a sealing portion a shown by a diagonal line in FIG. 1 is used.
1 was welded or adhered, and the portion e shown as the virtual seal portion in FIG. 1 was welded or adhered. Since the bag hanger device portion formed by such a manufacturing method has a structure in which two resin sheets are in close contact with each other, an open state is not formed unlike the weighing bag of the present invention.

Suitable materials for the resin sheet of the measuring bag A of the present invention include polyvinyl chloride, polyethylene, polypropylene and the like, but polyvinyl chloride is particularly preferable from the viewpoint of flexibility and heat resistance against sterilization. A tube c is formed as an inlet for draining liquid from the abdominal cavity and as a spout for draining liquid that has been filled and measured in the bag.
The tip of this tube c is connected to a line set for peritoneal dialysis, and the line set is usually constituted by including this measuring bag.

Next, a method of using the measuring bag of the present invention and its operation will be described. First, the metering bag cannot be used by itself, but is often used as part of the construction of a peritoneal dialysis line set. When attaching this line set to the peritoneal dialysis machine, the measuring bag
The bag hanger of the peritoneal dialysis device is passed through the bag hanger attachment site d and hung down. During the peritoneal dialysis treatment, the suspended measurement bag is filled with the impurity-containing dialysate discharged from the abdominal cavity and stored, and the measurement is performed so that the treatment is safely performed as prescribed. Thereafter, the dialysate is stored in the drainage container through the injected tube c. In the peritoneal dialysis treatment, this process is repeated several times. In the weighing bag of the present invention, since the bag hanger attachment site is in an open state, it can be easily passed through the bag hanger in the peritoneal dialysis device,
Therefore, the measurement bag can be attached very easily. The weighing bag of the present invention has been described above with reference to the drawings, but the present invention is not limited to these.

[0010]

In peritoneal dialysis, the line set to be used is mounted on the peritoneal dialysis device mainly by the dialysis patient himself, and may be carried out daily. If the bag hanger attachment site is in an open state like the weighing bag of the present invention, the bag hanger can be easily passed through the hanger attachment site, and the line set can be easily attached, which is troublesome at the time of attachment. It will be reduced.
