Definitions

• the present invention relates to an arrangement in a sterilizing coupling, more precisely to a coupling of the type described and illustrated in the International Application PCT/SE80/00019.
• a coupling in which a sterilizing action is obtained by utilizing a sealing ring prepared with a disinfectant, which gives off disinfectant to the coupling component which comes into contact with the ring during engagement.
• the object of the present invention is thus to provide a coupling of the type referred to in the International Application PCT/SE80/00019 , which is self-sterilizing during use. This object is achieved in accordance with the present invention in that the coupling has obtained the characteristics ' specified in claim 1.
• FIG. 1 shows a vertical section of the coupling in accordance with the invention before the coupling- element is connected to the coupling housing;
• FIG. 2 shows the coupling components according to FIG. 1 during initial engagement;
• FIG. 3 shows the coupling in the engaged position which permits through-flow; and
• FIG. 4 illustrates the coupling in a position wherein the coupling element is being disengaged from the coupling housing.
• FIG. 1 shows the coupling element 1 and coupling housing 2 in a disengaged position.
• the coupling housing has a movable slide 3 in which at least one recess 4 is arranged for accommodating a cover, and the coupling element 1 has a cover 5 which is received for displacement in a groove.
• the more detailed design of the coupling is disclosed in the International Application PCT/SE80/00019.
• the new feature of the coupling in accordance with the present invention is the arrangement of a casing 6 which is located around the coupling element 1.
• the casing 6 is preferably made from an elastic material , e.g. latex rubber, and extends up and over the cover 5.
• Two ring-shaped elements 7a and 7b with L-shaped cross section are arranged on both sides of the casing adjacent to the free end 6a of the casing ⁇ .
• a reinforcement can be moulded into the casing 6, which - similar to the elements 7a and 7b - is pushed in and sealingly rests against the internal peripheral surface of an abutment 8.
• a disinfectant e.g. spirit, which forms a barrier in respect of bacteria and also has a sterilizing effect on the coupling components during their engagement.
• FIG. 2 illustrates the coupling components during initial engagement, whereby the disinfectant is present in the cavity 10. By making the casing 5 elastic, this will expand somewhat during the continued insertion of the coupling element 1 into the coupling housing 2.
• FIG. 3 illustrates the two coupling components 1 and 2 in an engaged and locked position, said locking being achieved by displacement of the slide 3, i.e. the coupling permits free passage through both coupling components.
• external locking can also be provided between the coupling element 1 and the coupling housing 2, i. e. the coupling components should be capable of being locked in an engaged position without a free passage necessarily existing between the coupling components. This facilitates operation of the coupling by preventing the casing 6 pushing the coupling components apart.
• a locking device between the coupling components can for example comprise a spring lock, etc.
• the coupling element 1 with the casing 6 arranged thereon can be supplied complete with liquid disinfectant, which means that a cover 12 (FIG. 1) of a suitable type has to be provided at the free end 6a of the casing 6.
• Disinfectant is replenished as required in the casing 6.
