  The present invention relates to a peritoneal dialysate bag, and more particularly to a peritoneal dialysate bag capable of reducing the amount of dust.

  Conventionally, there has been a peritoneal dialysate bag shown in FIG. This is a configuration in which the drug solution bag and the drainage bag are Y-connected by a tube and the tip is connected to the patient's abdominal catheter, and a clamp is provided between the bag and the branch point. The chemical solution bag is filled with dialysate, and the drainage bag is empty.

  In use, the peritoneal catheter and peritoneal dialysate bag are connected, the drainage bag side clamp is opened, and the drug solution bag side clamp is closed, and the peritoneal drainage is discharged to the drainage bag. The side clamp is closed, the drug bag side clamp is opened, and the dialysate is fed into the abdominal cavity.

  After use, close both clamps, open the clamps in a toilet, etc., and drain the drainage. Thereafter, the peritoneal dialysate bag is discarded as household waste. Also, bring them to the hospital with the peritoneal drainage during regular checkups.

  Such a peritoneal dialysate bag is also disclosed in Japanese Patent Application Laid-Open No. 61-185275 (Patent Document 1), which makes it possible to connect the catheter and the bag as compared with the case where two separate bags are used. Reduced.

  In addition, the peritoneal dialysis instrument disclosed in Japanese Patent Application Laid-Open No. 5-269202 (Patent Document 2) discloses a technique that enables separation by using a drainage collection bag as a separate configuration. Can be easily performed.

However, the conventional technique has the following problems.
Peritoneal dialysis is required 4 to 5 times a day, and the size of the bag is, for example, about 40 cm × 25 cm for a 1500 ml bag, which is disclosed in Patent Document 1. However, the peritoneal dialysis solution bag in which two bags are set has a problem that the amount of dust becomes excessive.

  This is the same in Patent Document 2, even if the drainage bag can be separated, it is only convenient to carry and does not change as the amount of dust. Moreover, in any case, since a new drainage bag is used, there is a problem that it is uneconomical.

  In Patent Document 2, if the drainage bag is reused, the amount of dust is halved, but another problem arises that it gradually becomes unsanitary.

  In either case, since the portion connected to the abdominal catheter is idle after use, the liquid leaks when the clamp is removed, which is also unsanitary. In particular, when abdominal cavity drainage inspection is performed in a hospital, there is also a problem that when carrying, the clamp is released due to vibration or the like, fluid leaks and the surroundings become dirty.

It is the figure which showed the structural example of the peritoneal dialysate bag provided with the conventional 2 bags.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an external configuration diagram of the peritoneal dialysate bag of the present invention. 2 is a schematic diagram of a male connector, FIG. 3 is a schematic diagram of a female connector, and FIG. 4 is a schematic diagram of a clamp.

  The peritoneal dialysate bag 100 includes a drug solution bag 101, a tube 102, and a clamp 103. Next, each part will be described.

  The chemical solution bag 101 is a polypropylene bag filled with dialysate. The volume in the present embodiment is 1500 ml, but it may be 500 ml, 1000 ml, 2000 ml, 2500 ml, 3000 ml, 5000 ml. When the capacity is 1500 ml, the vertical and horizontal sizes are about 40 cm × 25 cm. The chemical solution is divided into large chamber liquid (960 ml) and small chamber liquid (540 ml) by the clip 111, the clip 111 is removed at the time of use, and the two chambers are alternately pushed with the palm to mix the liquid. In addition, it may replace with the clip 111 and may be a chemical | medical solution bag which is a weak seal, At this time, a weak seal is removed and used.

  These chemical solutions are filled through filling tubes 112a (small chamber fluid) and 112b (large chamber fluid), respectively, and sealed by heat treatment or stoppering. At the time of dialysis, the drug solution bag 101 is hung to a relatively high position by using the through hole 113 as appropriate. At this time, the mixed chemical solution is fed into the abdominal cavity according to gravity from the bag side tube end 127 integrally sealed at the sealing port 114.

  The tube 102 is a blend of polypropylene and a hydrogenated styrene-polyethylene-butadiene copolymer, extends from the sealing port 114, and branches into two in the middle. A male connector 121 is provided at one end, and a female connector 122 that is fluid-tightly connected to the male connector 121 is provided at the other end. The branch is located approximately 8 cm in the vicinity of the male connector 121, and is joined via a toroidal connecting pipe 126 so as to expand first when viewed from the male connector 121 side. Thus, when bifurcating asymmetrically, the male connector 121 and the female connector 122 can be distinguished from each other, and the operability is improved. Further, since the branch point is in the vicinity of the male connector 121, the male connector 121 and the G-shaped connecting pipe 126 are grasped together. Thereby, it becomes easy to catch the female connector 122 with the other hand, and the operability is enhanced from this point.

  In the unused state, the male connector 121 is fitted with a ring cap 124, and the female connector 122 is fitted with a convex cap 125. Since one end has a ring shape into which a finger can be inserted and the other has a general cap shape, and the tip shape is different, it is possible to distinguish which one is the male connector 121 from this point.

  The length of the tube 102 is not limited. For example, the length from the bag-side tube end 127 to the G-shaped connecting pipe 126 is 70 cm, the length from the G-shaped connecting pipe 126 to the male connector 121 is 8 cm, and the G-shaped connecting pipe 126 to the female connector. Up to 122 can be 50 cm. Thus, when the male connector side tube length <the female connector side tube length <the chemical solution bag side tube length, the visibility is improved and the operability by the patient can be improved.

  A feature of the peritoneal dialysate bag 100 is that the male connector 121 and the female connector 122 are complementarily joined. As shown in FIG. 2, the male connector 121 includes a convex tube portion 141 that enters the septum 155, a screw projection 142 that is screwed into the female connector 122, and a tube 102. And a slot 143. The ring cap 124 is provided with a cylindrical body 144 that encloses the convex tube portion 141, and a screwing groove 145 that is engaged with the male connector 121 via the screwing protrusion 142. Due to the housing of the cylindrical body 144 and the male connector 121, the convex tube portion 141 is doubly blocked from the outside air and can be stored hygienically. Further, the screwing groove 145 is symmetrically cut so that the ring cap 124 can be detached from the male connector 121 clockwise or counterclockwise. At the time of detachment, the index finger is inserted into the ring 146 and rotated either or the ring 146 is pulled to remove the ring cap 124.

  As shown in FIG. 3, the female connector 122 includes a septum 155 having a slit S at the tip, and joins the convex tube portion 141 of the male connector 121 in a liquid-tight manner. At the time of joining, when the male connector 121 is screwed clockwise, the screwing protrusion 142 of the male connector 121 is guided by the screwing protrusion 151 and the screwing groove 152, and the male connector 121 is locked by the joining hole 153. The The female connector 122 also has an insertion port 157 into which the tube 102 is inserted. The convex cap 125 has a protrusion 156 inside and fits over the protrusion 154 of the female connector 122, and attaches the convex cap 125 to the female connector 122 stably. This realizes hygienic storage. Note that the convex cap 125 and the ring cap 124 can be joined to each other by the protrusion 156 and the protrusion 147.

  The male connector 121 and the female connector 122 are made of polypropylene, and the ring cap 124 and the convex cap 125 are also made of polypropylene. However, the present invention is not limited to this, and may be made of, for example, polycarbonate or polyacetal.

  As shown in FIG. 4, the clamp 103 has a wedge shape in which a part thereof is open, and is provided with a through hole 131 and a through hole 132 through which the tube 102 is inserted. It is the structure which cuts off liquid flow by. Since the tube 102 is passed through the through holes 131 and 132, the clamp 103 is not dissipated and convenience is enhanced. Note that the present invention is not limited to the clamp 103, and other mechanisms may be used as long as the tube 102 can be opened and closed.

  The pressing parts 133 and 134 are pressed by pressing down the pressing part 135, and their tips are locked and fixed to the claw part 136 in which the barb is formed. At the time of opening, if the claw portion 136 is pushed, it is detached by the entire elastic force. The clamp 103 can be pressed and released with one hand by the above configuration.

  Next, peritoneal dialysis using a peritoneal dialysate bag set in which two peritoneal dialysate bags 100 are connected will be described. FIG. 5 is an explanatory diagram of peritoneal dialysis using a peritoneal dialysate bag set in which two peritoneal dialysate bags 100 are connected. Here, it is assumed that the capacity of the chemical solution bag 101 is 1500 ml.

  In the present embodiment, an abdominal catheter extends from the abdominal cavity of the patient, and the same connector as the female connector 122 (hereinafter referred to as connector C) is formed at the end thereof. And The connector C is joined to the same cap as the convex cap 125 except when dialysis (this is appropriately expressed as a cap K), so that the septum is hygienically protected.

  The peritoneal dialysate bag set 200 is a combination of a new first peritoneal dialysate bag 100A containing a chemical solution and an empty second peritoneal dialysate bag 100B used in the previous peritoneal dialysis (hereinafter, For convenience of explanation, A is added to the end of the reference sign of each part belonging to the first peritoneal dialysate bag 100A, and B is added to the end of the reference sign of each part belonging to the second peritoneal dialysate bag 100B).

  In use, first, it is confirmed that the clamp 103A and the clamp 103B are closed, and the male connector 121A and the female connector 122A of the first peritoneal dialysate bag 100A are connected to the connector C and the second peritoneal dialysate bag, respectively. It is joined to the male connector 121B of 100B (FIG. 5 (a)). Next, the clamp 103B of the second peritoneal dialysate bag 100B is opened, and the peritoneal drainage is discharged from the medicinal solution bag 101B of the second peritoneal dialysate bag 100B (see FIG. 5B).

  Next, the clamp 103B of the second peritoneal dialysate bag 100B is closed, the clamp 103A of the first peritoneal dialysate bag 100A is opened, and the dialysate is fed into the abdominal cavity (FIG. 5 (c)).

  Finally, the clamp 103A of the first peritoneal dialysate bag 100A is closed, each joint is disconnected, the male connector 121A and the female connector 122A of the first peritoneal dialysate bag 100A are joined, and the second peritoneal dialysate bag The 100B male connector 121B and the female connector 122B are joined (FIG. 5D).

  The first peritoneal dialysate bag 100A is stored as the next second peritoneal dialysate bag 100B. Further, in the second peritoneal dialysate bag 100B filled with the peritoneal drainage, the male connector 121B and the female connector 122B are appropriately removed at the toilet or the like, the clamp 103B is opened, and the peritoneal drainage is discarded from the male connector 121B. The empty peritoneal dialysate bag 100B is treated as household waste.

  As described above, the peritoneal dialysate bag 100 can be reused as a drainage bag after use, and therefore, compared to the conventional two-bag product as described in Patent Document 1 in which a new drug solution bag and a new drainage bag are joined. And there is an advantage that garbage is reduced by half. In addition, the double closure by the clamp closure and the male / female short circuit prevents leakage particularly during the transfer of the peritoneal drainage and improves the hygiene. Even if the ring cap 124 and the convex cap 125 are lost, the male connector 121 and the female connector 122 do not have to be exposed to the outside air, so that the convenience is also improved in this respect.

  Depending on the mode of use, each end may be sterilized and then shorted or capped.

  Further, the female connector 122 is not provided with a septum, and each of the tube 102 portion between the G-shaped connecting pipe 126 and the female connector 122, the tube 102 portion between the G-shaped connecting pipe 126 and the male connector 121, or one side (female connector). A clamp may be provided on the 122 side). FIG. 6 is an explanatory view showing a state of the clamp attachment centering on the tube portion in the peritoneal dialysate bag of another embodiment. Here, a slide type clamp 103 ′ is mounted on both the male connector 121 side and the female connector 122 side, the tube is closed on the male connector 121 side, and the tube is opened on the female connector 122 side.

  In the above-described embodiment, the capacity of the chemical solution bag is 1500 ml. However, the present invention is not limited to this, and both the unused chemical solution bag and the used chemical solution bag are appropriately joined to each other. The amount of drainage may be changed. For example, as shown in FIG. 7A, a plurality of new drug solution bags can be connected as an infusion solution, and peritoneal dialysis fluid exceeding the prescribed amount of the container (bag) can be infused into the patient. As shown in Fig. 7 (b), a plurality of used drug solution bags can be connected to store abdominal cavity reservoir fluid exceeding a specified amount for drainage (in the figure, one side already drains abdominal cavity reservoir fluid). Is shown).
