Description

  The present invention relates to a drainage bag used for CAPD (continuous portable peritoneal dialysis) and other peritoneal dialysis and a peritoneal dialysis fluid set including the same, and more particularly, to a drainage bag structure that increases the production efficiency of the peritoneal dialysis fluid set.

  Conventionally, a peritoneal dialysis fluid set for CAPD is composed of an outer packaging material in which a peritoneal dialysis fluid bag in which a dialysis fluid is sealed and a drainage bag to which a fluid passage tube is joined are sterilized and sealed. It is distributed as something to do.

  The volume of the dialysate is, for example, 2000 ml, and in order to perform the discharge process to the drain bag immediately after dialysis, the liquid passing tube joined to the drain bag has a diameter of about 10 mm. A large diameter is used and the length is as long as about 100 cm. Therefore, in the manufacturing process, the liquid passing tube is made into a double or triple ring and inserted into the outer packaging material together with the drainage bag.

  However, on the production line, simply by making a ring, the tube diameter is large, so the restoring force to be straight becomes large, and even if it is manual work or automated, it will be out of shape and the production efficiency will deteriorate. There was a problem.

  In order to improve this, there has also been devised a form in which a liquid passing tube in a ring is sandwiched between two folded drainage bags and fastened with a tape. However, the tape fastening has a problem that it is practically difficult to automate because the tube posture is not always constant.

  On the other hand, it can be taped manually, but in the case of such a medical product, an operator needs to use gloves to ensure hygiene. In this case, there is a problem in that the tape frequently sticks to the glove, deteriorating workability and remarkably deteriorating the production efficiency.

  Further, since the peritoneal dialysate set is finally heated by high-pressure steam sterilization, there is a concern about the volatilization of the adhesive on the tape. From this viewpoint, it is preferable from the viewpoint of increasing waste. Absent.

It is explanatory drawing which showed the structure before use of the drainage bag of this invention from the state before accommodation of a tube. It is the elements on larger scale of the drainage bag which accommodated the tube. It is explanatory drawing which showed the mode of accommodation to the outer packaging material 3 of a drainage bag and a peritoneal dialysate bag.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an explanatory view showing a structure before use of the drainage bag according to the present invention from a state before housing the tube. FIG. 2 is a partially enlarged view of a drainage bag containing a tube. FIG. 3 is an explanatory view showing how the drainage bag and the peritoneal dialysate bag are accommodated in the outer packaging material 3. In the figure, for convenience of display, the components are drawn with the components simplified or omitted.

  The drainage bag 1 is basically composed of a storage bag 10 and a tube 20.

  The storage bag 10 is formed as a liquid-tight bag by overlapping two identical rectangular sheets having a length of about 30 cm, a width of about 20 cm, and a thickness of about 1 mm, and a peripheral width of 12 mm. The four corners are chamfered. Further, the sheet is a five-layer sheet in which the inner side (side contacting the drainage) is made of polypropylene and the outer side is made of polybutylene terephthalate.

  The tube 20 is a PP tube having an outer diameter of 7 mm and an inner diameter of 5 mm. One end of the tube 20 enters the housing bag 10 and a connector 21 is attached to the other end. In addition, a liquid stop clip 22 slidable on the tube 20 is inserted in the middle. The length of the tube is about 100 cm. The tube 20 is branched into a Y shape near the connector 21, and the branched tube 20 is connected to the peritoneal dialysate bag 2.

  The infiltration position of the tube 20 is a position about 3 cm from the end of the short side of the storage bag 10, and the drainage liquid after peritoneal dialysis is passed through the storage bag 10. It should be noted that the tube 20 and the storage bag 10 are bonded with a liquid-tight property as a matter of course.

  On the production line, the drainage bag 1 is held by being inserted into a folded storage bag 10 by rolling the tube 20 as follows.

  First, the containing bag 10 is folded in half so that the short sides are aligned. As shown in FIG. 1, for the sake of convenience, the folding line when folded in two, that is, the side where the so-called “wa” is formed is L1, and the left and right sides (long half side) are connected to L2, L3, and L1. Let L4 be the side opposite to.

  Next, the tube 20 is triple-wound and inserted into the housing bag 10 so that the connector 21 is pressed against L1 from the inside. That is, the connector 21 is positioned so as to be applied to the valley folded portion of the containing bag 10.

  At this time, the liquid stop clip 22 is slid and the long side of the tube 20 that is far from the entry position of the tube 20 into the storage bag 10 (the entry portion is located on the L2 side in FIG. 1). In this case, it is brought to the L3 side).

  Finally, the two overlapping edges located near the vertex on the L4 side of the left and right sides L2 and L3 are spot-fused with an ultrasonic staple (hereinafter, the L2 side fusion spot is referred to as S2 and L3 side). The fusion spot is appropriately referred to as S3). At this time, the tube 20 is prevented from protruding from the left and right sides L2 and L3.

  At the same time, the edge around 1/4 from the end on the opposite side of the opposite side L4 from the end close to the position where the tube 20 enters the storage bag 10 is spot-fused by ultrasonic staple (hereinafter, this fusion spot). Is appropriately referred to as S4). At this time, the bundle of tubes 20 is sandwiched between the spots S3 and S4.

  Of course, the fusing strength is such that the fusing strength is such that the tube 20 does not peel with a restoring force that makes the tube 20 straight, but can be easily peeled with human power. This setting depends on the ultrasonic staple used, but is performed by adjusting the pressing force and pressing time of the head. Further, the fusion location is set around the center of the edge width as a guide so as not to be too close to the inside of the containing bag 10. This is to maintain liquid tightness. In this embodiment, the spot shape has a linear shape of 1 mm × 3 mm.

  Since the drainage bag 1 is formed so as to have the above-described posture, the tube 20 is held in the storage bag 10 and is excellent in stability. In general, the tube 20 is thick and long, and if the tube 20 is bent, bent, or wrinkled, the product reliability is lowered. Therefore, the tube 20 cannot be entirely accommodated in the half-folded storage bag 10, and a part of the side L4 Although it must be protruded, the tube 20 does not run out even if vibration is applied to the drainage bag 1 in the subsequent lines by adopting the above-described form, and the housing operation into the outer packaging material 3 Also improves.

  Note that the position of the spot S2 is a position from the end on the L4 side to 1/4 on L2. Similarly, the position of the spot S3 is from the end on the L4 side to 1/4 on L3. In any case, it is preferably up to 1/5.

  The position of the spot S4 is around 1/4 on L4, but is preferably 1/6 to 1/3 from the end. However, since S3 and S4 cooperate to prevent the tube 20 and the liquid stop clip 22 from slipping down, considering the thickness of the tube 20, the number of windings (number of bundles), and the size of the clip 22, S3 and S4 are appropriately selected. Most preferably, S4 is positioned.

  Further, a plurality of locations to be fused may be provided on each side. The fusing unit is not an ultrasonic staple, and other heat fusing unit or heat fusing unit can be used as appropriate.

  As shown in FIG. 3, the drainage bag 1 formed in this way is joined to the two-part peritoneal dialysis fluid bag 2 after joining the other end of the tube 20 to the peritoneal dialysis fluid. It is sandwiched between the bags 2 and inserted into the outer packaging material 3. The inside of the outer packaging material 3 is then sterilized by EOG gas and enclosed, and the peritoneal dialysis set is completed.

  As described above, the drainage bag 1 realizes stable holding of the tube 20 by fusion using the edge originally provided in the storage bag 10 and improves workability and manufacturing efficiency. It is suitable because it is a joining that does not use a new member such as a tape, and since it is not a joining that uses a solvent such as an adhesive, the solvent does not volatilize, adhere, or penetrate, and product reliability is maintained. In addition, since the tube 20 itself and the connector 21 at the tip of the tube 20 do not play until the folded folding bag 10 is opened, hygiene is maintained and good handling can be provided.

  The present invention can be used for CAPD, APD, and other dialysis.
