Definitions

  • the invention relates to a bag according to the preamble of claim 1.
  • Such a pouch is used in particular in a system for carrying out an outpatient dialytic withdrawal of metabolic products excreted by damaged kidneys of a patient.
  • the pouch takes up the used dialysate that is removed from the patient's abdominal cavity.
  • Outpatient peritoneal dialysis can be carried out by a kidney-damaged patient himself without interruption for twenty-four hours a day and seven days a week, e.g. with the CAPD at least four times a day.
  • the used dialysate is discharged into the above-mentioned bag and fresh dialysate is introduced into the patient's abdominal cavity from another bag.
  • Peritoneal dialysis removes metabolic substances that have been eliminated from the damaged kidneys of the patient from the patient's body, whereby he can devote himself to his usual daily activities during the change cycles.
  • a Tenckhoff catheter 2 is inserted into the abdominal cavity 1 of a patient.
  • the outer end of the catheter 2 is connected to a separating device 5 via a coupling device 3 and a piece of hose 4.
  • a three-way distributor 6 is connected to the separating device 5, on the one hand via a supply hose 7 with a bag 8 containing fresh dialysate and on the other hand is connected via a discharge hose 9 to the bag 10 according to the invention for receiving the used dialysate.
  • the system is connected to the catheter 2 by means of the coupling piece 3.
  • the used dialysate passes from the abdominal cavity 1 through the catheter 2 and the three-way distributor 6 into the bag 10.
  • the three-way distributor is switched to its second position, so that the fresh dialysate present in the bag 8 passes over the three-way distributor 6 and the catheter 2 can flow into the abdominal cavity 1.
  • the hose piece 4 is clamped in by means of the separating device 5 to prevent the flow and the part of the hose 4 connected to the three-way distributor 6 is separated.
  • FIG. 2 shows part of a section along the line II-II of FIG. 1 and shows that the bag 10 is produced from a composite film 13 comprising two plastic films 11 and 12.
  • the bag 10 and the plastic films 11 and 12 are shown for better clarity because of excessive thickness.
  • the bag 10 comprises the discharge hose 9, one end of which is inserted into the actual bag 10 and welded to it.
  • a connector 14 made of plastic is fastened, which is described in more detail below with reference to FIG. 5.
  • the composite film 13, from which the bag 10 and the discharge tube 9 are made, comprises a polyester film 11 and a polypropylene film 12.
  • Known bags are, for example, only made from a polypropylene film, but because of the low strength of the polypropylene, the polypropylene film must be chosen so thick that these known bags are no longer transparent but only translucent.
  • the composite film 13 is therefore selected according to the invention, the polyester film 11 being responsible for the sufficient tear resistance, while the polypropylene film 12 can be welded at a much lower temperature than the polyester film, and can be chosen to be so thin that the desired transparency of the bag 10 is achieved becomes.
  • the polypropylene film 12 which is preferably weldable below 100 ° C., is located on the inside of the bag, while in the discharge hose 9, the polypropylene film 12, with the exception of the seam areas, is on the outside and the polyester film 11 is on the inside of the hose 9. Because the polypropylene films 12 are located on the inside of the bag 10, the bag 10 can be produced in a known welding process by placing two of the composite films 13 on top of one another and welding the edge regions 15 of the two polypropylene films 12 lying against one another along the entire circumference. The weld seam is shown in dash-dot lines in FIG. 2 and provided with the reference number 16.
  • FIG. 2 further shows a cross section through the discharge hose 9 opening into the bag 10.
  • the hose 9 is made from the same composite film 13 as the bag 10, but with the polypropylene film 12 on the outside of the hose 9 located.
  • one end of the tube 9 is not between the ver welded composite films 13 placed.
  • the welding process is carried out, not only the edge region 15 of the two polypropylene films 12 is welded to one another in the region of the hose 9, but also said edge regions 15 are simultaneously welded to the adjacent polypropylene films 12 of the hose 9 to form a weld seam 17.
  • the two adjacent polyester films 11 of the tube 9 are not welded to one another because the softening temperature of the polyester films 11 is higher than the welding temperature of the polypropylene films 12.
  • the discharge hose 9 is produced by rolling the longitudinal edges 19 of two strips of the composite film 13 in such a way that the polypropylene films 12 are on the outside, so that parts 20 of the propylene films 12 lie against one another over the entire length when the strips are placed on one another, so that during the subsequent welding process these parts of the polypropylene films 12 are welded together.
  • the tube 9 thus has two weld seams 21 which extend over the entire length of the tube 9 and have a thickness which is at least twice the thickness of the composite film 13.
  • the weld seams 21 prevent the passage through the hose 9 from being blocked when the hose 9 is kinked or folded. This would be the case, for example, if a seamless hose were used instead of the hose 9.
  • the weld seams 21 are preferably such that when the hose is folded 9 there is a passage with a cross section of at least 7 mm2.
  • the polyester film 11 is located on the inside of the tube 9. Because the polyester film has good wettability compared to the dialysate, this has a favorable effect on the dialysate flowing through the tube 9 into the bag 10.
  • FIGS. 3 and 4 show the cross section through a second and a third embodiment of the discharge hose.
  • the composite film 13 is shown as a whole in FIGS. 3 and 4 for the sake of simplicity and is not divided into the inner polyester film and the outer polypropylene film.
  • the longitudinal edges are not rolled up, as in the embodiment according to FIG. 2, but are bent in a zigzag shape.
  • the polypropylene film parts in contact are welded to one another to form weld seams 23. In this way, edge regions are again created, the thickness of which is several times greater than the thickness of the composite film 13.
  • the third exemplary embodiment of the hose 24 shown in FIG. 4 has only a single, rolled-in weld seam 25 that extends over the entire length of the hose 24.
  • the weld seam 25 also prevents the passage through the tube 24 from being completely blocked when it is kinked or folded.
  • the connector 14 is arranged. 5 this end of the hose 9 is shown in section.
  • the annular connector 14 consists of one with the sen lying polypropylene film 12 of the tube 9 weldable plastic.
  • the connecting piece 14 is preferably sprayed onto the polypropylene film 12 of the hose 9 and is connected to the polypropylene film 12 by a type of welded seam shown in broken lines.
  • the connector 14 is preferably made of polypropylene.
  • the connector 14 can also be formed as part of a bayonet, screw or luer lock.
  • FIG. 6 shows a further embodiment of a bag 26 according to the invention, which in plan view has the shape of an isosceles triangle with an acute angle, a neck piece 29 adjoining this angle.
  • the bag 26 is also made from the composite film 13 described above.
  • the polypropylene film is located on the outside and the polyester film on the inside of the bag 26 and the neck piece 29. So that the two triangular composite film pieces 27 can be welded along their edges when the bag 26 is manufactured, the edge regions of the composite films are unique folded inwards so that areas of the polypropylene films touch each other and can be welded to form a weld seam 28 which almost completely surrounds the bag 26 and the neck piece 29.
  • edge areas of the inner polyester films can be glued to one another with the aid of an adhesive, a strip-shaped adhesive site then almost completely surrounding the bag 26 and the neck piece 29 instead of the weld seam 28.
  • the bag adjoining the neck piece (29) can also be rectangular, round or bottle-shaped.
  • the connecting piece 14 is arranged, that is to say sprayed onto the outside polypropylene film 12 of the bag 26.
  • the bags 10 and 26 described above are transparent, which enables a first visual inspection of the used dialysate and filled into the bag, and have sufficient strength.
  • these bags can be steam sterilized and their manufacturing costs can be kept very low.
