Definitions

  • the invention relates to a coupling piece for a medical line arrangement, as is used for example in peritoneal dialysis.
  • the treatment medium supplied from a periodically replaceable storage container must be supplied via a coupling piece to the line system going to the patient. Since the coupling must therefore be opened each time the container is changed, the risk of contamination during this process is quite high.
  • the coupling piece according to the invention results from claim 1.
  • the coupling piece shown in axial section has the two coupling parts 1 and 2 and is penetrated by channels 10 and 11.
  • the two coupling parts 1, 2 are positively connected to one another by a snap connection.
  • an additional locking element 3 is provided as an additional locking element; this engages with a peripheral rib 5a in a correspondingly shaped groove 5g of the coupling part 1, while its other end a thread 6 is screwed to the coupling part 2.
  • the two O-rings 7 at both ends of the union nut 3 With the help of the two O-rings 7 at both ends of the union nut 3, the transition point between the two coupling parts is completely sealed off from the outside.
  • the union nut is provided with an inwardly projecting safety cam 17 which prevents the claw of the snap lock 4 from escaping radially and thus prevents this lock from being released unintentionally.
  • 1.2 hose nipples 8,8a and 9,9a are provided at both ends of the coupling parts for connecting the hose lines.
  • the sealing surface between the two coupling parts is designed for the Eanal lo as a double cone 12 and for the channel 11 as a single cone 13. Due to the conical design of the contact surfaces, an additional adhesive force is obtained between the two coupling parts by a friction fit.
  • outflow openings 15 are present, which open into a cavity surrounding the connection starch of the parts 1, 2.
  • dialysis fluid is led from the reservoir to the patient via the channel 10, while a disinfectant is fed into the line 11.
  • the hose line connected to the hose nipple 9a is closed off by a manually operated valve.
  • the valve mentioned is opened after the reassembly and a stream of disinfectant is pressed through the cavities 16, so that any infection germs that may be present are rinsed out.
  • the valve is then closed and the cavities 16 always remain completely filled with the disinfectant during the subsequent treatment period.

Abstract

Un tel dispositif de raccordement doit d'une part empêcher toute contamination lors de l'ouverture du raccord, d'autre part la liaison des pièces de jonction doit être telle qu'elle rende pratiquement impossible une ouverture intempestive durant le traitement de dialyse. Ceci est obtenu en verrouillant entre elles les deux pièces de jonction (1, 2) à l'aide d'une fermeture à cran (4) et en maintenant ensemble les deux pièces au moyen d'un manchon d'accouplement (3). Une came de sécurité (17) fait saillie à l'intérieur du manchon (3) contre les griffes de la fermeture à cran et rend ainsi impossible son ouverture lorsque le manchon est vissé. Deux canaux (10, 11) s'étendent à travers le dispositif de raccordement; l'un conduit le fluide de traitement, l'autre un désinfectant. A travers des orifices de sortie (15) dans la paroi du deuxième canal (11) le désinfectant parvient dans un espace vide (16) qui entoure la région de raccordement des deux pièces de jonction de manière telle que cet espace est toujours rempli de désinfectant, ou en cas de besoin est rincé par celui-ci.
