Abstract
Description
On connaît et on utilise depuis longtemps les raccords munis d'embouts maie et.-relle pour fixer les aiguilles aux seringues, ou pour intercaler,entre les deux,robinets et autres accessoires, ou encore pour connecter entre eux des cathéters avec et sans robinet ou accessoires divers
Les techniques modernes de cathétérisme nécessitent souvent l'emploi de cathéters "co-axiaux", c'est-à-dire dont le plus fin coulisse aisément dans le plus gros. Les connexions en sont forcement compliqudes et souvent réalisées de façon très artisanale.It has been known and used for a long time the fittings provided with maie et.-relle tips for fixing the needles to the syringes, or for interposing, between the two, taps and other accessories, or even for connecting catheters with and without tap between them. or various accessories
Modern catheterization techniques often require the use of "co-axial" catheters, that is to say the finest of which slides easily in the largest. The connections are necessarily complicated and often carried out in a very traditional way.
L'emploi "d'introducteurs" n'a pas revoulu toutes les difficultés à vaincre dans ce domaine. Conçus pour faciliter les échanges de cathéters sans trop fortement léser l'artère ponctionnée, au cours, par exemple, des examens angiographiques, les introducteurs ne permettent pas de modifier le choix du diamètre des cathéters quand cela s'avère nécessaire. The use of "introducers" did not overcome all the difficulties to be overcome in this area. Designed to facilitate the exchange of catheters without damaging the punctured artery too much, during, for example, angiographic examinations, the introducers do not allow the choice of catheter diameter to be changed when necessary.
La présente invention a pour but de fournir un raccord à valve adaptable sur toutes tubulures, introducteurs, et accessoires à usage médical, pour le cathétérisme cardiaque ou autre, pour les transfusions, perfusions, examens angiographiques ou phiébographiques, etc. The present invention aims to provide a valve fitting adaptable to all tubing, introducers, and accessories for medical use, for cardiac or other catheterization, for transfusions, infusions, angiographic or phiebographic examinations, etc.
ta première de ses caractéristiques est d'être muni d'enbouts de connexion à verrou lui permettant d'être connecté avec les tubulures, et accessoires divers utilisés en angiographie, dans le cathétérisme en général ou spécialisé, les transfusions, perfusions etc. et d'être constitué de deux parties, l'une distale, l'autre proximale, présentant un orifice axial pour le passage d'un catheter intérieur. Ces deux parties sont séparées par une valve qui, pendant les échanges de cathéters, s'oppose au reflux sanguin et permet d'introduire, par un orifice latéral prévu sur la partie distale, un second liquide entre deux injections, par exemple un liquide héparinisé, qui s'oppose d la coalugation du sang et à la formation de caillots. your first of its characteristics is to be provided with lock connection ends allowing it to be connected with the tubes, and various accessories used in angiography, in catheterization in general or specialized, transfusions, infusions etc. and to be made up of two parts, one distal, the other proximal, having an axial orifice for the passage of an internal catheter. These two parts are separated by a valve which, during catheter exchanges, opposes blood reflux and makes it possible to introduce, by a lateral orifice provided on the distal part, a second liquid between two injections, for example a heparinized liquid. , which opposes the coalugation of blood and the formation of clots.
La seconde caractdrîstique concerne la valve qui est constitue de deux rondelles souples dont chacune comporte une fente selon une ligne médiane. Ces rondelles sont superposdes en opposition l'une par rapport à l'autre, pour assurer l'étanchéité des cathéters de différents diamètres. The second characteristic concerns the valve which is made up of two flexible washers, each of which has a slot along a median line. These washers are superposed in opposition to each other, to seal the catheters of different diameters.
La troisième caractéristique concerne les embouts dont le raccord à valve est muni. Ils sont du type à verrou, à pas rapide, maie du coté proximal, et femelle du côté distal, par exemple "Luer Lock",qui lui assurent un montage facile et des connexions étanches sur tubulures, introducteurs, et accessoires divers. The third characteristic concerns the nozzles with which the valve connection is provided. They are of the lock type, with quick pitch, but on the proximal side, and female on the distal side, for example "Luer Lock", which ensure easy mounting and tight connections on tubing, introducers, and various accessories.
Une quatrième caractéristique du raccord b valve est sa réalisation en une seule pièce évidée à l'interieur où elle comporte un élé ment de maintien pour la valve, par exemple un épaulement, servant à loger cette valve du côté proximal, et une butée du côté distal pour retenir l'embout femelle du cathéter extérieur dans lequel l'embout maie du raccord à valve est introduit et fixé. A fourth characteristic of the valve b connection is that it is produced in a single piece, hollowed out inside, where it comprises a holding element for the valve, for example a shoulder, used to house this valve on the proximal side, and a stop on the side. distal to retain the female tip of the outer catheter into which the tip of the valve fitting is inserted and fixed.
En variante le raccord à valve est réalisé en deux éléments séparés et fixés l'un dans l'autre, l'élément distal s'emboiant dans l'élément proximal en y maintenant la valve. As a variant, the valve connection is made of two separate elements and fixed one inside the other, the distal element fitting into the proximal element while holding the valve there.
Un tel raccord à valve peut servir à la réalisation d'un INTRO DUCTEUR. Un "dilatateur" est alors connecté sur l'embout maie de 19eld- ment distal. Une "gaine"pénêtre par l'orifice proximal, traverse les deux éléments du raccord et le dilatateur, dont elle ressort par son ex- trêmité libre. Après ponction et mise en place de l'introducteur, la gaine peut être remplaacée, à volonté, par tout cathéter de diamètre égal ou inférieur à celui de cette gaine, avec une parfaite étanchéité et sans risque de reflux sanguin. Such a valve connection can be used to make an INTRO DUCTEUR. A "dilator" is then connected to the male distal elongation tip. A "sheath" penetrates through the proximal orifice, crosses the two elements of the connector and the dilator, from which it emerges by its free end. After puncture and placement of the introducer, the sheath can be replaced, at will, by any catheter with a diameter equal to or less than that of this sheath, with a perfect seal and without risk of blood reflux.
A titre d'illustration des dessins sont fournis: - La figure 4 représente le raccord à valve sensiblement en vrai gran- deur. Bien qu'on puisse faire l'inverse, l'embout à verrou femelle (1) est situé du côté proximal, et l'embout à verrou maie (2) du côté distal, cette solution étant la plus rationnelle. By way of illustration, drawings are provided: - Figure 4 shows the valve connection substantially in real size. Although the opposite can be done, the female bolt tip (1) is located on the proximal side, and the male latch tip (2) is located on the distal side, this solution being the most rational.
- La figure 2 représente le raccord à valve très agrandi, dans le cas òu il est réalisé en une seule-pièce. Sur l'embout à verrou femelle t1) figure en trait fin l'embout mâle ftant, du côté proximal, un cathéter extérieur (9). Sur l'embout à verrou maie (2) figure en trait fin l'em- bout femelle fixant, du côté distal, un cathéter extérieur (8) allant vers le patient. Passant dans l'ensemble, un cathéter intérieur (10) passe du cathéter extérieur proximal (9) au cathéter extérieur distal (8) en traversant complement le raccord à valve, et sans solution de comti- nuité. L#orifice latéral (5) permet l'introduction d'un socond liquide pendant les échanges éventuels du cathéter intérieur , donc entre deux injections.- Figure 2 shows the greatly enlarged valve connection, in the case where it is made in one piece. On the female latched tip t1) is shown in thin line the male tip being, on the proximal side, an external catheter (9). On the lockable end piece (2) is shown in thin line the female end fitting fixing, on the distal side, an external catheter (8) going towards the patient. Passing through the assembly, an internal catheter (10) passes from the proximal external catheter (9) to the distal external catheter (8) by passing through the valve connection completely, and without any joint solution. The lateral orifice (5) allows the introduction of a liquid base during the possible exchanges of the interior catheter, therefore between two injections.
- ta figure 3 montre les rondelles souples formant valve, la rondelle su- périeure (6) ayant sa fente médiane en opposition avec celle de la rondelle inférieure (7).FIG. 3 shows the flexible washers forming a valve, the upper washer (6) having its central slot in opposition to that of the lower washer (7).
- La figure 4 montre les rondelles (6 et 7) vues selon A-A. - Figure 4 shows the washers (6 and 7) seen according to A-A.
- La figure 5 montre en coupe éclatée le raccord à valve lorsqu'il est réalisé en deux éléments, l'élément distal (2) s'eaboitant dans l'éié- ment proximal (1), les rondelles de la valve étant maintenues entre les les deux pièces. - Figure 5 shows in exploded section the valve connection when it is made in two elements, the distal element (2) snapping into the proximal element (1), the washers of the valve being held between the two pieces.
- La figure 6 représente un raccord à valve constitué en "introducteur".- Figure 6 shows a valve connection consisting of "introducer".
Le "dilatateur" (3) est connecté sur l'embout maie (2) de l'élément distal. La "gaine" (4) pénêtrant dans l'axe de l'embout du cêté proximal (1) traverse les deux éléments du raccord à valve, pénêtre dans le dilatateur (3) et en ressort à son extrêmité distale. Son retrait permettra de la remplacer par tout cathéter ayant un diamètre égal ou inférieur au sien, avec une parfaite étanchéité et sans reflux sanguin. Pendant ces échanges, donc entre deux injections, un second liquide pourra être introduit par le tube monté sur l'orifice latéral (5). The "dilator" (3) is connected to the core tip (2) of the distal element. The "sheath" (4) penetrating in the axis of the tip of the proximal side (1) crosses the two elements of the valve connection, penetrates into the dilator (3) and emerges at its distal end. Its removal will allow it to be replaced by any catheter with a diameter equal to or less than its own, with a perfect seal and without blood reflux. During these exchanges, therefore between two injections, a second liquid may be introduced through the tube mounted on the lateral orifice (5).
