Abstract

The catheter comprises an outer sleeve contg. several tubes each with its inlet end extending separately from the outer end of the catheter. Pref. one tube only has an outlet corresp. with the axial orifice at the inner end of the catheter. The other tubes discharge via lateral orifices in the wall of the sleeve near the inner end of the catheter. Pref. a spiral guide wire or leader is extended through the tube with axial orifice in order to allow the catheter to be introduced by the Seldinger method.

Description

La présente invention concerne un cathéter permet- tant la mise en perfusion par raccordement direct à plusieurs flacons de soluté, ce cathéter comportant un tube à plusieurs conduits pourvu chacun d'un système d'alimentation distinct et débouchant à l'extrémité distale par un orifice separé. The present invention relates to a catheter allowing infusion by direct connection to several bottles of solute, this catheter comprising a tube with several conduits each provided with a separate feeding system and opening at the distal end through an orifice. separate.

Dans les dispositifs connus d'admission simultanée de plusieurs solutés, le raccordement des arrivées est réalisé en amont d'un cathéter à simple conduit, par exemple par une rampe de robinets ou par divers raccords à dérivation latérale, ce qui provoque la perturbation du débit de chacun des solutés en application du principe des vases communicants.In the known devices for the simultaneous admission of several solutes, the connection of the arrivals is carried out upstream of a single-line catheter, for example by a ramp of taps or by various fittings with lateral bypass, which causes the disturbance of the flow of each of the solutes in application of the principle of communicating vessels.

La présente invention à pour objet d'améliorer l'admission des différents solutés par leur séparation complote jusqu'à leur sortie dans le vaisseau.The object of the present invention is to improve the admission of the various solutes by their separation in conspiracy until their exit into the vessel.

Cet objet est réalisé grâce à un tube (1) à l'ex- trématé proximale conique (2) comportant plusieurs conduits < 3)(4)(5)(6). Ce tube forme un cathéter grâce à un conduit principal (s) et un orifice cen- tré (7) par lesquel on peut introduire un guide spiralé (13) qui lui même permet l'introduction du cathéter dans le vaisseau selon la technique du
Dr Seldinger. Parallèlement au conduit principal (5) se trouvent un ou plusieurs autres conduits (3)(4)(6) débouchant chacun par un orifice latéral (8)(9) la) du cathéter. A son extrémité proximale cônique 2) le cathéter comporte des arrivées séparées ( équipée chacune d'un raccord standard Luer (12) pouvant être branché sur les tubulures des flacons de solutés, soit directement soit avec un robinet permettant la coupure de l'une ou l'autre des alimentations.This object is produced by means of a tube (1) at the conical proximal end (2) comprising several conduits <3) (4) (5) (6). This tube forms a catheter thanks to a main conduit (s) and a centered orifice (7) through which one can introduce a spiral guide (13) which itself allows the introduction of the catheter into the vessel according to the technique of
Dr. Seldinger. In parallel with the main conduit (5) there are one or more other conduits (3) (4) (6) each opening out through a lateral orifice (8) (9) 1a) of the catheter. At its conical proximal end 2) the catheter has separate inlets (each equipped with a standard Luer connector (12) which can be connected to the tubes of the solute vials, either directly or with a tap allowing the cutting of one or more the other of the power supplies.

Ce cathéter à plusieurs conduits est réalisé en matière synthétique, de préférence opaque aux RX. This catheter with several conduits is made of synthetic material, preferably opaque to X-rays.
