9. The catheter valve assembly according to claim 8, wherein the main body further comprises a metallic plate with magnetic properties arranged opposite the one side of the valve hose where the movable magnet is arranged.

10. The catheter valve assembly according to claim 8, further comprising an integrated or bilaterally pluggable safety device configured to be arranged on the stepped barbed part of the inlet and on a connected catheter.

11. The catheter valve assembly according to claim 10, wherein the safety device is a U-shaped double-sided clamp.

12. The catheter valve assembly according to claim 8, wherein the outlet comprises a barbed part over which the adapter is configured to flexibly slip.

13. The catheter valve assembly according to claim 8, wherein the outlet comprises a barbed part for engaging a locking ring of the adapter.

14. The catheter valve assembly according to claim 13, wherein the slider is configured to be held in the open position by the adapter when the locking ring of the adapter is engaged with the barbed part at the outlet.

15. The catheter valve assembly according to claim 8, wherein the catheter valve assembly is configured such that removal of the adapter from the outlet causes the longitudinally movable slider to move to the closed position.

(21) FIG. 19 shows a catheter valve with integrated catheter protection

(22) The catheter valve has a main body 1 with an inlet 2 and an outlet 3 (FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10). At the inlet 2 there is a stepped barbed part 4 for receiving the catheter 5 from the patient. The valve hose 6 is guided through the main body 1. On the main body 1, a longitudinally movable slider 7 is arranged, on which in the interior of the main body 1 two contradirectionally arranged downward inclines 8; 9 are located. By a longitudinal movement of the slider 7, the two magnets 10; 11 are moved over the downward inclines 8; 9 up or down in the vertical direction, thereby closing or opening the cross-section of the valve hose 6. The two magnets 10; 11 move up or down in two inclined chambers 12a; 13a against two vertically extending chambers 12b; 13b.

(23) On the stepped barbed part 4, a groove 14 is arranged on the main body 1, into which one side of the double-sided clamp 15 engages (FIG. 7). The other side of the double-sided clamp 15 accesses the stepped barbed part 4 and the catheter 5, which is pushed onto the stepped barbed part 4.

(24) The double-sided clamp 15 has, on the side aligned with the catheter 5, a special pointed geometry 16 with preferably three points, which means that the three points engage in the silicone material of the catheter 5 under tensile stress and thus prevent unintentional disconnection (FIG. 11, 12, 15, 16, 17, 18).

(25) (FIG. 19) shows an integrated embodiment in which the double-sided clamp with the main body 1 consists of one component.

(26) The adapter 17 is attached to the outlet 3 of the main body 1, to which the urine bag connection is connected (FIGS. 13, 14). When inserting the adapter 17, the slider 7 is moved in a longitudinal direction to abutment, thereby pushing it into the open position.

(27) When the adapter 17 is removed, the catheter valve should preferably close automatically. This can be achieved by the magnetic force exerted on one another by the magnets 10, 11, which force is preferably sufficiently strong such that the magnets 10, 11 move towards one another along the downward inclines 8,9 and move towards each other while guided in the vertical guide formed by the vertical chambers 12b, 13b, while pushing the longitudinally movable slider 7 back into its initial position and pinching and thus closing the valve hose 6 located between the two magnets 10,11.
