Application to medical treatments.

Description

La présente invention concerne une canule d'injection. The present invention relates to an injection cannula.

Plus précisément, elle concerne une canule d'injection comprenant une gaine, une partie de poignée et une partie de cathéter. Selon l'invention, la partie de poignée a un organe de saisie dans lequel est montée une canule, la partie de cathéter est un cathéter raccordé à une base de cathéter et est supporté par la canule, et la gaine, à l'état monté, entoure la canule, le cathéter qu'elle supporte et une partie au moins de la base du cathéter. More specifically, it relates to an injection cannula comprising a sheath, a handle part and a catheter part. According to the invention, the handle part has a gripping member in which a cannula is mounted, the catheter part is a catheter connected to a catheter base and is supported by the cannula, and the sheath, in the mounted state , surrounds the cannula, the catheter which it supports and at least part of the base of the catheter.

Les dessins annexés représentent un mode de réalisation de canule d'injection destinée à être utilisée dans un traitement médical. The accompanying drawings show an embodiment of an injection cannula for use in medical treatment.

D'autre caractéristiques et avantages de l'invention seront mieux compris à la lecture des dessins annexés sur lesquels
- les figures 1 et 2 sont des vues en perspective représentant la canule dans sa totalité, la canule étant transparente sur la figure 1 et non transparente sur la figure 2, et
- les figures 3 et 4 sont des vues éclatées des canules des figures 1 et 2.Other characteristics and advantages of the invention will be better understood on reading the appended drawings in which
FIGS. 1 and 2 are perspective views showing the whole cannula, the cannula being transparent in FIG. 1 and not transparent in FIG. 2, and
- Figures 3 and 4 are exploded views of the cannulas of Figures 1 and 2.

On décrit dans la suite ce mode de réalisation plus en détail en référence aux figures 1 à 4 sur lesquelles les parties analogues portent des références identiques. This embodiment is described below in more detail with reference to FIGS. 1 to 4 in which the analogous parts bear identical references.

La série de figures 1 à 4 représente un premier mode de réalisation de canule d'injection 2 qui, dans sa totalité, est représentée sur les figures 1 et 2. Elle comporte une gaine tubulaire allongée 4 qui est raccordée temporairement à une partie 6 de poignée, comme indiqué sur les figures 3 et 4. Comme l'indique clairement la figure 3, la partie 6 de poignée supporte une partie 8 de cathéter qui est représentée plus en détail sur la figure 4 et qui comporte un cathéter 12 solidaire d'une base 10 de cathéter. La partie 6 de poignée comporte en outre une canule 14 fixée à un organe 16 de saisie qui est lui-même raccordé temporairement à un dispositif 18 de fermeture qui, lors de l'utilisation de la canule d'injection, permet le passage d'air en même temps qu'il arrête le reflux sanguin provenant du système sanguin.Le dispositif 18 de fermeture est pratiquement tubulaire et il contient un filtre 20. Après enlèvement du dispositif 18 de fermeture de l'organe de saisie 16, cet organe peut être raccordé par exemple à une seringue (non représentée). The series of FIGS. 1 to 4 represents a first embodiment of injection cannula 2 which, in its entirety, is shown in FIGS. 1 and 2. It comprises an elongated tubular sheath 4 which is temporarily connected to a part 6 of handle, as shown in Figures 3 and 4. As clearly shown in Figure 3, the handle portion 6 supports a catheter portion 8 which is shown in more detail in Figure 4 and which has a catheter 12 integral with a catheter base 10. The handle part 6 further comprises a cannula 14 fixed to a gripping member 16 which is itself temporarily connected to a closure device 18 which, when the injection cannula is used, allows the passage of air at the same time as it stops the blood reflux coming from the blood system. The closure device 18 is practically tubular and it contains a filter 20. After removal of the closure device 18 from the gripping member 16, this member can be connected for example to a syringe (not shown).

La canule 2 d'injection est utilisée de la manière suivante. Après enlèvement de l'emballage entourant la canule 2, la gaine 4 est retirée et, à l'état monté, elle entoure totalement la canule 14, le cathéter 12 supporté par la canule ainsi que la base 10 du cathéter et la partie avant de l'organe de saisie 16. Pour que la gaine 4 soit fixée de manière satisfaisante, sa partie interne a au moins une partie en saillie 26 qui, à l'état monté de la gaine, est en contact derrière un épaulement 28 placé au bord avant de l'organe de saisie 16. L'enlèvement de la gaine 4 libère la canule 14 et le cathéter 12 qu'elle supporte. La gaine 4 et l'organe 16 de saisie ont des gorges et nervures 22 et 24 respectivement placées dans la direction longitudinale de la canule 2 afin qu'elles permettent une saisie fiable lors de l'enlèvement de la gaine 4 et du maniement ultérieur de la canule 2. La canule 14 est alors introduite sous la peau et dans le vaisseau sanguin, le cathéter 12 étant ainsi placé dans le vaisseau sanguin. Lorsque le dispositif 18 de fermeture est retiré, il est possible d'appliquer par exemple une seringue. Après enlèvement de la canule, la base 10 du cathéter peut être raccordée à un autre appareillage médical, par exemple une source de liquide transmis au vaisseau sanguin. The injection cannula 2 is used in the following manner. After removal of the packaging surrounding the cannula 2, the sheath 4 is removed and, in the assembled state, it completely surrounds the cannula 14, the catheter 12 supported by the cannula as well as the base 10 of the catheter and the front part of the the gripping member 16. In order for the sheath 4 to be fixed satisfactorily, its internal part has at least one projecting part 26 which, in the assembled state of the sheath, is in contact behind a shoulder 28 placed at the edge before the gripping member 16. The removal of the sheath 4 releases the cannula 14 and the catheter 12 which it supports. The sheath 4 and the gripping member 16 have grooves and ribs 22 and 24 respectively placed in the longitudinal direction of the cannula 2 so that they allow a reliable gripping during the removal of the sheath 4 and the subsequent handling of the cannula 2. The cannula 14 is then introduced under the skin and into the blood vessel, the catheter 12 thus being placed in the blood vessel. When the closure device 18 is removed, it is possible to apply for example a syringe. After removal of the cannula, the base 10 of the catheter can be connected to other medical equipment, for example a source of fluid transmitted to the blood vessel.

Bien entendu, diverses modifications peuvent être apportées par l'homme de l'art aux canules qui viennent d'être décrites uniquement à titre d'exemples non limitatifs sans sortir du cadre de l'invention.  Of course, various modifications can be made by those skilled in the art to the cannulas which have just been described only by way of nonlimiting examples without departing from the scope of the invention.
