Definitions

  • the present invention relates to a device for accessing a pocket made of flexible synthetic material.
  • a device for accessing a pocket made of flexible synthetic material is used in particular in the medical field for perfusion bags for example.
  • the tube is a flexible extruded tube (made of polyvinyl chloride for example) and cut to the desired length. It is generally attached to the flexible bag by welding.
  • the perforable access is then fixed on the free side of the tube by gluing or by natural adhesion during steam sterilization for example. It has a thin perforable wall closing the access to the pocket and called the hymen.
  • the access device to the bag is generally provided with a protection.
  • the latter is fixed so that it can only be removed by breaking or tearing.
  • the welding of the tube on the pocket is difficult to achieve. Indeed, the end of the tube is placed in an opening made in the pocket and the edge of this opening is welded around the periphery of the tube. The weld therefore surrounds the tube. This is all the more difficult to realize that the tube is of small section.
  • Patent application FR 94 02614 in the name of the Applicant describes a pocket comprising an access provided with a flat collar. Thanks to this, it is then possible to secure the tube on the flexible bag using a flat weld. This type of welding is easy to perform, but this solution does not make it possible to reduce the number of parts necessary to make the access device. In addition, when emptying a bag of flexible material equipped with a tube provided with a flat collar, there remains a non-negligible residual volume of liquid inside the bag.
  • the object of the invention is then to provide an access device to a pocket of flexible synthetic material, easily connectable to this pocket and produced in one piece, while guaranteeing sterility and inviolability of access to the pocket.
  • this access device also allows good emptying of the pocket on which it is fixed.
  • the access device that it offers is of the type comprising a flange mounted at a first end of an access tube as well as a thin, perforable wall, placed inside the tube and separating from watertight inside the tube in two areas.
  • the wall of the tube has a thinned annular zone placed between the thin perforable wall and the second end of the tube and this second end of the tube is closed by a weld.
  • the device thus obtained is therefore in one piece and guarantees sterility, thanks to the welding, and the inviolability of access to the bag, thanks to the thinned annular zone.
  • the thinned annular zone constitutes a tear initiation.
  • To access the thin perforable wall simply grasp the welded end and turn it relative to the rest of the tube.
  • the torque thus exerted causes a tear or level in the thinned area. This operation is irreversible, it guarantees the inviolability of access to the flexible bag.
  • This access device is intended to be fixed on the fold of a pocket made of flexible synthetic material.
  • the flange of the access tube is folded and has, perpendicular to this fold, a V-shaped section whose base is rounded.
  • the internal face of the V of the collar follows the natural shape of a fold of a filled pocket on which is intended to be fixed. the access device.
  • the latter is flattened in the shape of a duckbill.
  • any other form of welding that may be carried out may be suitable.
  • the invention also proposes a method of manufacturing this access device. According to this mode, it is obtained by molding a tube comprising a flange at a first end, a thin perforable wall placed inside the tube and a thinned annular zone, then by welding the second end of the tube. This welding is preferably a high frequency welding.
  • Figures 1 and 2 show an access device 1 of thermoplastic material injection molded before it undergoes the operation of closing one of its ends by welding.
  • Figures 3 and 4 show the same access device 1 once this welding has been carried out.
  • This access device comprises a tubular part, or tube 2, a thin wall 3 also called a hymen and placed transversely in the tube 2, a flange 4 produced at a first end of the tube 2 and a thinned annular zone 5. It is intended to be welded, thanks to the collar 4, to a pocket of flexible synthetic material 6 of polyvinyl chloride for example, at a fold 7 of this pocket 6.
  • the collar 4 has the general shape of a circular ring folded according to one of its diameters. Perpendicular to this diameter, it has a V-shaped section with a rounded base ( Figure 2).
  • the angle formed by the two branches of the V, the curvature of the rounding are chosen so that the collar 4 conforms as best as possible to the fold 7 of the bag, when the latter is filled with liquid, for example perfusion liquid .
  • High frequency welding can be replaced by thermal welding or by any other type of welding adapted to the materials used.
  • the shape of the core used, and in particular of the bearing surface, resumes the shape of the interior of a pocket filled with liquid.
  • a first zone 8 on the side of the flange 4 is in connection with the interior of the pocket 6, the second zone 9 being in FIG. 2, in the open air.
  • Hymen 3 is perforable. It allows the passage of a trocar while ensuring sealing at the level of the outer surface thereof.
  • the second zone 9 of the tube carries the thinned annular zone 5 of the access device. This constriction constitutes a pre-tearing zone.
  • FIG. 3 shows the access device 1 in its final form, before use of the flexible bag 6.
  • the end of the tube 2 situated opposite the flange 4 beyond the thinned zone 5 is welded. It was flattened between two electrodes of a high frequency welding device and closed by welding. It then has a shape reminiscent of a duckbill.
  • the thinned zone 5 is not affected by the welding of the end of the tube 2. To then access the contents of the pocket 6, it suffices then to grasp the flattened and welded end 10 and to rotate it relative to the rest of the tube 2 to separate it at the level of the pre-tear zone 5.
  • the access device 1 described above has many advantages. First of all, it is made in one piece. This allows to have low manufacturing costs, but also avoids generating particles, since it is not necessary to make cuts to obtain such a device.
  • the collar 4 makes it possible to weld an access tube to a pocket using a "flat" weld. Even if the collar 4 is not flat, its welding does not have the drawbacks of an annular weld necessary for welding a tube without collar to a pocket.
  • the folding of the collar makes it possible to obtain a very good emptying of the pocket and to maintain the parallelism of the accesses when a pocket has several accesses.
