Coupling for peritoneal dialysis units

Abstract

Abstract Coupling for peritoneal dialysis units, consisting of: a sleeve 1 with an elastic absorbent body 10 fixed therein for taking up bactericidal fluid; a mandrel 2 sited on the patient side and with a longitudinal channel 20 and sharply tapered end 24 which is mounted inseparably and displaceably in the sleeve 1 and can be locked in both end positions; a cylindrical insert 4 which can be pushed into the sleeve from the end 1A thereof on the bag side and has a further absorbent elastic body 40 for taking up bactericidal fluid; and a coupling part 3 which is sited on the bag side and has a longitudinal channel 30 which can be pushed into the sleeve 1 and can be locked in the inserted state. The mandrel 2, in the advanced position, protrudes through the fixed elastic body 10 and through the elastic body 40 located in the insert 4 and it protrudes into the mouth of the longitudinal channel 30 of the coupling part 3, which mouth is covered by a membrane 31 prior to the coupling procedure. <IMAGE>
