Catheter valve for controlling the fluid flow of a medium
A catheter valve for controlling the fluid flow of a medium, in particular a self-closing catheter valve, wherein a main body includes: —an inlet and an outlet-, —a flexible tube, —as a cover, a slider which is movable in the longitudinal direction, and —at the inlet of the catheter valve, a stepped barbed part for connecting a supply line; and, in the interior of the main body that comprises two laterally opposite vertical chambers, the catheter valve has two contradirectional downward inclines on the longitudinally movable slider for actuating and guiding two vertically movable magnets, which are arranged on two opposite sides of the valve house and selectively close or open the passage of said valve hose, wherein an adapter can be inserted and fastened at the outlet of the catheter valve and (in addition to the longitudinally movable slider) results in a permanent open position of the catheter valve.
1 . A catheter valve assembly comprising:
an elongate main body having an inlet, an outlet and an interior;
a flexible valve hose extending through the interior of the main body in fluid communication with the inlet and the outlet, said valve hose defining a passage; and
a slider coupled to the main body, said slider being selectively movable longitudinally relative to the main body between a closed position and an open position;
wherein the main body includes a stepped barbed part at the inlet for establishing a connection to a catheter,
wherein two movable magnets are arranged in the interior of the main body on opposite sides of the valve hose,
wherein the interior of the main body includes guide channels within which portions of the two movable magnets are received,
wherein the longitudinally movable slider includes two contradirectional inclines,
wherein the two contradirectional inclines of the slider and the guide channels of the main body are configured to act upon and guide the two movable magnets such that
in the closed position of the slider the two movable magnets are drawn toward each other, the valve hose is compressed between the two movable magnets, and the passage through the valve hose is closed, and
in the open position of the slider the two movable magnets are separated from each other, the valve hose is not compressed between the two movable magnets, and the passage through the valve hose is open, and
wherein the outlet is configured to be inserted into and fastened to an adapter that holds the longitudinally movable slider in the open position.
2 . The catheter valve assembly according to claim 1 , 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.
3 . The catheter valve assembly according to claim 2 , wherein the safety device is a U-shaped double-sided clamp.
4 . The catheter valve assembly according to claim 1 , wherein the outlet comprises a barbed part over which the adapter is configured to flexibly slip.
5 . The catheter valve assembly according to claim 1 , wherein the outlet comprises a barbed part for engaging a locking ring of the adapter.
6 . The catheter valve assembly according to claim 5 , 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.
7 . The catheter valve assembly according to claim 1 , 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.
8 . A catheter valve assembly comprising:
an elongate main body having an inlet, an outlet, and an interior;
a flexible valve hose extending through the interior of the main body in fluid communication with the inlet and the outlet, said valve hose defining a passage; and
a slider coupled to the main body, said slider being selectively movable longitudinally relative to the main body between a closed position and an open position;
wherein the main body includes a stepped barbed part at the inlet for establishing a connection to a catheter,
wherein a movable magnet is arranged in the interior of the main body on one side of the valve hose,
wherein the interior of the main body includes guide channels within which portions of the movable magnet is received,
wherein the longitudinally movable slider includes an incline,
wherein the incline of the slider and the guide channels of the main body are configured to act upon and guide the movable magnet such that
in the closed position of the slider the movable magnet compresses the valve hose and closes the passage through the valve hose, and
in the open position of the slider the movable magnet does not compress the valve hose and the passage through the valve hose is open, and
wherein the outlet is configured to be inserted into and fastened to an adapter that holds the longitudinally movable slider in the open position.
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.
