Definitions

  • the invention relates to a venous catheter, in particular an indwelling vein catheter, with a T-shaped connecting piece, which has at its three ends a first, a second and a third connecting piece, the opposite connecting pieces being connected to one another via an infusion channel into the
  • An injection channel formed by the third connecting piece opens at right angles via a disposable injection valve, an infusion tube being connectable to the first connecting piece, while the second connecting piece carries the actual catheter, which holds a steel cannula, and the third connecting piece for inserting a syringe is designed in the form of a socket and can be closed by a cover cap, and the one-way injection valve is formed by an elastic hose which is arranged in the flow path of the infusion channel and which, in its rest position which keeps the infusion channel open, the injection channel l seals against the infusion channel and is deformed somewhat when the injection channel is acted upon under the pressure of the injection liquid acting on it, thereby lifting it out of its closed position and thus connecting the injection channel to the second connecting
  • the catheter is placed in a vein by puncturing this vein with the steel cannula and then pushing the catheter over the steel cannula into the vessel. As soon as the steel cannula has been pulled out of the indwelling catheter so far that it no longer completely seals the catheter, blood flows back into the infusion channel. Also when changing the infusion tube, blood or infusion liquid drips out of the first connection piece. In practice, the user helps himself to firmly press the vein immediately in front of the tip of the indwelling catheter.
  • the invention is based on the object of using simple means to eliminate the risk of contamination of the catheter or a risk of infection due to the blood escaping or infusion liquid with blood admixture.
  • the cover cap is designed as a thrust piece which is displaceable in the axial direction against the action of a resilient element on the third connecting piece and which, from its inoperative position which keeps the infusion channel open, into a the Shut-off position blocking the infusion channel can be pressed, in which a pressure piston connected to the pressure piece compresses the wall of the elastic hose facing it at a partial section in such a way that this partial section seals and thus blocks the infusion channel against the opposite hose wall, while at least one of the first connecting pieces facing section of the elastic tube maintains its rest position sealing the injection channel from the infusion channel.
  • the venous catheter provided with a backstop according to the invention can retain all of its previous functions, the backstop being able to be switched on as often or as desired, either briefly or permanently.
  • a great advantage can also be seen in the fact that the system according to the invention can be used universally for all common intravenous catheter systems. A complex and therefore expensive retrofitting of conventional indwelling catheters is not necessary. Since in the blocking position at least one section of the elastic hose facing the first connecting piece maintains its rest position, which seals the injection channel from the infusion channel, direct contact between the liquid in the infusion channel and the piston is also prevented.
  • a particularly simple and functionally reliable embodiment can be achieved in that a guide piece is pushed onto the third connecting piece, which has a central sliding guide for the pressure piston and a jacket surface on the jacket side for the pressure piece that overlaps the guide piece. If an injection syringe is then to be inserted into the socket-shaped third connection piece in a conventional manner, only the pressure piece covering the injection channel together with the guide piece need be removed from the third connection piece as a unit. This unit remains connected to the catheter by the retaining ring and is put back on the third connection piece after the injection.

If an injection syringe is inserted and actuated in the socket-shaped third connecting piece 5, then the The elastic tube 9 is somewhat deformed under the pressure of the injection liquid acting on it, thereby lifting it out of its closed position and thus connecting the injection channel 8 to the second connection piece 4 assigned to the catheter 3.

Abstract

L'invention concerne un cathéter veineux, en particulier un cathéter veineux à demeure. Ce cathéter est pourvu d'une pièce d'assemblage en T (1) présentant un premier (2), un deuxième (4) et un troisième (5) embout sur ses trois extrémités. Le premier embout (2) sert au raccordement d'un tuyau de perfusion ; le deuxième embout (4) porte le cathéter (3) logeant une canule en acier et le troisième embout (5) est conçu sous forme de douille pour l'insertion d'une seringue et peut être fermé par un capuchon. L'objectif de cette invention est d'empêcher tout risque de contamination du cathéter. A cet effet, le capuchon est conçu sous la forme d'une pièce à compression (10), placée de façon à pouvoir se déplacer en sens axial contre l'effet d'un élément à déformation élastique sur le troisième embout (5). Cette pièce peut être comprimée dans une position de retenue retenant le conduit de perfusion (6) à partir de sa position initiale maintenant ouvert ledit conduit de perfusion (6). En position de retenue, un piston de compression (11), relié à ladite pièce à compression (10), comprime la paroi du tuyau élastique (9) faisant face à ce piston, de sorte que cette paroi appuie contre la paroi de tuyau opposée (9b) de façon étanche et de façon à retenir le conduit de perfusion (6), tandis qu'au moins une section (9c) du tuyau élastique (9), faisant face au premier embout, conserve sa position initiale isolant le canal d'injection (8) par rapport au conduit de perfusion (6).
