Abstract: The invention relates to a catheter, particularly a permanently implanted catheter, particularly a peritoneal-dialysis one, particularly for such peritoneal dialysis where a catheter tube is positioned normally to the surface area at the location of implantation, which catheter consists of a flexible catheter tube and at least one cuff, which is stable in its position on the catheter tube. The catheter tube provides a length segment (A) beginning next to the patient's skin, the general flexibility of the said length segment being greater than that of the remaining length section of the catheter, so that the catheter tube protruding from the patient's abdomen easily bends at the said length segment without collapsing (being squeezed).

Abstract: According to the invention the inflow funnel/duct insertion 10 stable in its shape is by its funnel part 15 matingly inserted into an entering chamber 13 of a receptacle 1 which is unstable in its shape and is suitably made of foil, with a socket 17 of the funnel/duct insertion 10 provided for receiving a test tube 21 projects from the receptacle 1.

Abstract: Apparatus used with a seated patient for separately catching successive streams of urine for taking samples for laboratorial and bacteriological examination. The apparatus enables an automatic separation of initial, median, and final streams caught in a vessel. The vessel also is used to transport the sample from the patient to a laboratory.
