Abstract
Description
SERINGUE PERFECTIONNEE A DOUBLE COMPARTIMENT.IMPROVED DOUBLE COMPARTMENT SYRINGE.
L'invention concerne une seringue perfectionnée à double compartiment. The invention relates to an improved double compartment syringe.
Dans l'art dentaire notamment, on connait déjà des seringues à double compartiment destinée à réaliser au dernier moment le mélange de deux produits liquides. In dentistry in particular, we already know syringes with double compartments intended to produce at the last moment the mixing of two liquid products.
Une telle seringue se compose essentiellement
- d'un premier corps contenant un premier liquide, effilé à son extrémité libre afin de recevoir l'aiguille d'injection
- d'un second corps contenant le deuxième liquide, emmanché dans le premier corps et apte à coulisser librement dans celui-ci de manière étanche et dont l'extrémité aval est bouchée par une membrane étanche, afin d'ernpêcher la diffusion du deuxième liquide dans le premier corps, mais apte toutefois à être rompue sous l'effet d'une pression
- un piston destiné à comprimer le liquide contenu dans le deuxième corps et à le pousser dans le premierecorps pour le mélanger avec le premier liquide.Such a syringe basically consists
- a first body containing a first liquid, tapered at its free end in order to receive the injection needle
- a second body containing the second liquid, fitted into the first body and capable of sliding freely in the latter in a sealed manner and the downstream end of which is blocked by a waterproof membrane, in order to prevent the diffusion of the second liquid in the first body, but nevertheless capable of being broken under the effect of pressure
- a piston intended to compress the liquid contained in the second body and to push it into the first body to mix it with the first liquid.
Bien que ces seringues soient utilisées avec succès dans l'art dentaire, notamment pour des ciments de scellement ou des résines, elles présentent encore certains inconvénients, notamment si on désire les utiliser en chirurgie. En effet, dans de nombreux cas, il est indispensable que le mélange des deux liquides soit parfaitement homogène. Although these syringes are successfully used in dentistry, especially for sealing cements or resins, they still have certain drawbacks, especially if one wishes to use them in surgery. Indeed, in many cases, it is essential that the mixture of the two liquids is perfectly homogeneous.
Pour ce faire, actuellement, l'opérateur,dans un premier temps, enfonce le piston dans le deuxième corps et sous l'effet de la pression exercée, la membrane étanche placée à l'extrémité du deuxième corps qui débouche dans le premier, se rompt et ainsi le deuxième corps liquide contenu dans ce deuxième corps est poussé dans le compartiment non totalement occupé du premier corps qui contient le premier liquide. Les deux liquides étant ainsi mélangés dans le premier corps, l'opérateur, dans un deuxième temps, place la seringue sur un appareil agitateur par vibrations pour homogénéiser le mélange. Une fois ce mélange homogénéisé, l'opérateur arrête la vibration et la seringue, après avoir placé une aiguille d'injection à l'extré- mité effilée, est alors prête à l'emploi. To do this, currently, the operator, firstly, pushes the piston into the second body and under the effect of the pressure exerted, the waterproof membrane placed at the end of the second body which opens into the first, is thus breaks the second liquid body contained in this second body is pushed into the not fully occupied compartment of the first body which contains the first liquid. The two liquids are thus mixed in the first body, the operator, in a second step, places the syringe on a vibrating shaker to homogenize the mixture. Once this mixture has been homogenized, the operator stops the vibration and the syringe, after placing an injection needle at the tapered end, is then ready for use.
Un tel processus dans lequel on utilise une machine ne présente pas les exigences requises de stérilité et ne peut être mis en oeuvre dans un bloc opératoire. Such a process in which a machine is used does not have the required sterility requirements and cannot be carried out in an operating theater.
De la sorte, malgrè un intérêt technique certain, ce système de mélange au dernier moment de deux composés liquides, n'a pu être utilisé en milieu chirurgical ou en milieu stérile, ce qui est fort regrettable.In this way, despite a certain technical interest, this system of mixing at the last moment of two liquid compounds, could not be used in a surgical environment or in a sterile environment, which is very regrettable.
L'invention pallie ces inconvénients. Elle concerne une seringue perfectionnée du type en question à double compartiment, dans laquelle on peut effectuer commodément l'agitation du mélange tout en ne faisant pas appel à un matériel indépendant et tout en maintenant l'ensemble en milieu stérile. The invention overcomes these drawbacks. It relates to an improved syringe of the type in question with a double compartment, in which the agitation of the mixture can be conveniently carried out while not requiring the use of independent equipment and while maintaining the assembly in a sterile environment.
Cette seringue perfectionnée du type comprenant
- un premier corps contenant un premier liquide,
- un second corps contenant un deuxième liquide, emmanché dans le premier corps et apte à coulisser librement de manière étanche dans celui-ci, et dont l'extrémité aval est bouchée par une membrane étanche destinée à empêcher la diffusion du deuxième liquide dans le premier corps, mais apte à se rompre sous l'effet d'une pression exercée sur le deuxième liquide,
- un piston emmanché dans le deuxième corps, et apte à coulisser dans celui-ci, destiné à comprimer le deuxième liquide contenu dans le deuxième corps et à le pousser dans le premier corps pour le mélanger au premier liquide, se caractérise en ce que le premier corps comporte également un organe apte à se mouvoir dans le premier corps tout en assurant une action d'agitation du mélange contenu dans ce premier corps.This improved syringe of the type comprising
- a first body containing a first liquid,
a second body containing a second liquid, fitted into the first body and capable of sliding freely in leaktight manner therein, and the downstream end of which is blocked by a waterproof membrane intended to prevent the diffusion of the second liquid in the first body, but able to rupture under the effect of a pressure exerted on the second liquid,
- A piston fitted into the second body, and capable of sliding therein, intended to compress the second liquid contained in the second body and to push it into the first body to mix it with the first liquid, is characterized in that the first body also comprises a member capable of moving in the first body while ensuring an agitating action of the mixture contained in this first body.
En pratique
- l'organe agitateur se déplace-dans le premier corps dans un mouvement longitudinal d'aller et retour
- l'organe agitateur est formé par un axe longitudinal rotatif à ailettes qui pénètre dans le premier corps
- l'extérieur de l'axe longitudinal de l'agitateur présente sur une longueur sensiblement égale à celle du premier corps, un filetage hélicoïdal destiné à coopérer avec un filetage identique taillé à l'extrémité aval du premier corps, de sorte que sous l'effet d'une poussée longitudinale exercée à l'extrémité de cet axe longitudinal, celui-ci en s'enfonçant dans le premier corps se met, comme une toupie, à tourner sur lui-même et ainsi à entraîner en rotation les ailettes placées à son extrémité amont et situées dans le premier corps.;;
- l'extrémité aval de l'axe longitudinal présente un moyen tel qu'un bouton apte à tourner librement autour de cette extrémité aval et à permettre d'exercer une poussée longitudinale sur ledit axe longitudinal
- l'extrémité amont de l'axe longitudinal rotatif qui est connecté aux ailettes d'agitation est creux sur une partie au moins égale à l'épaisseur de l'extrémité aval du premier corps et la zone de séparation entre cette partie creuse et le reste de la partie pleine de l'axe longitudinal présente une amorce de rupture, de sorte que, une fois l'homogénéisation du mélange réalisée, il suffit, après avoir ramené les ailettes à l'avant du premier corps, de casser l'axe longitudinal à hauteur de cette séparation, pour permettre au mélange contenu dans le premier corps d'être évacué, éventuellement après avoir adapté une aiguille à l'extrémité aval du premier corps. In practice
- the agitator moves in the first body in a longitudinal movement back and forth
- the agitating member is formed by a rotary longitudinal axis with fins which penetrates into the first body
- The outside of the longitudinal axis of the agitator has over a length substantially equal to that of the first body, a helical thread intended to cooperate with an identical thread cut at the downstream end of the first body, so that under the effect of a longitudinal thrust exerted at the end of this longitudinal axis, the latter sinking into the first body starts, like a top, to rotate on itself and thus to rotate the fins placed at its upstream end and located in the first body. ;;
the downstream end of the longitudinal axis has a means such as a button able to rotate freely around this downstream end and to allow a longitudinal thrust to be exerted on said longitudinal axis
the upstream end of the rotary longitudinal axis which is connected to the stirring fins is hollow over a part at least equal to the thickness of the downstream end of the first body and the separation zone between this hollow part and the rest of the solid part of the longitudinal axis has a breaking point, so that, once the mixture has been homogenized, it is sufficient, after having brought the fins back to the front of the first body, to break the axis longitudinal at the height of this separation, to allow the mixture contained in the first body to be evacuated, possibly after having adapted a needle at the downstream end of the first body.
La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux de l'exemple de réalisat#ion qui suit, donné à titre indicatif et non limitatif à l'appui des figures annexees. The manner in which the invention can be implemented and the advantages which result therefrom will emerge more clearly from the exemplary embodiment # ion which follows, given by way of nonlimiting indication in support of the appended figures.
La figure 1 montre en coupe longitudinale l'ensemble conforme à l'invention. Figure 1 shows in longitudinal section the assembly according to the invention.
La figure 2 est également une coupe longitudinale d'une vue détaillée de l'extrémité aval du premier corps et de l'organe d'agitation incorporé. FIG. 2 is also a longitudinal section of a detailed view of the downstream end of the first body and of the incorporated stirring member.
La seringue perfectionnée se compose
- d'un piston (1) cylindrique à corps plein, par exemple en matière plastique injectée telle que polye- tiylène ou autre matière plastique similaire, comportant en amont une tête d'appui (2) et en aval un pointeau (3) portant des joints (4) venus de moulage, destinés à assurer l'étanchéité ;;
- un compartiment creux cylindrique (5), formant deuxième corps, également en matière plastique moulée de même nature que le piston (1), destiné à recevoir le deuxième liquide (10), comportant à son extrémité amont des oreillettes (6) eC une butée d'arrêt et d'étanchéité (7), et à son extrémité aval
d'une part, une mince membrane d'étanchéité
(8) destinée à éviter le passage du deuxiè
me liquide (10) dans le premier corps (11),
apte à se rompre sous l'effet de la poussée
exercée par le piston (1) sur le liquide
(10) ; à titre indicatif, cette membrane
(8) peut être un film quelconque compatible,
soit collée sur la face aval, soit obtenue
directement lors du moulage du deuxième
corps (5)
d'autre part, de joints (9), identiques à
à (4)
- un second compartiment creux cylindrique (11) formant le premier corps, de même nature que (5), destiné à recevoir le premier liquide (12), et dont le volume total disponible est égale à la somme des volumes des deux liquides (10) et (12) à mélanger ; le deuxième corps (5) est apte à se déplacer comme un piston dans ce premier corps (11) qui présente
à à son extrémité amont, des oreilles d'ap
pui (13) pour l'injection et une butée
d'arrêt et d'étanchéité (14) analogue à (7)
à à son extrémité aval, un cone effilé (15)
rapporté, montré en détail à la figure 2
- un ensemble agitateur incorporé formé par un axe longitudinal (16) apte à se déplacer dans le premier corps (11) dans un mouvement de va-et-vient grâce à la structure détaillée à la figure 2, et qui présente
à à son extrémité aval (18) un bouton (19)
ou tout autre moyen équivalent de préhen
sion, apte à tourner librement autour de
cette extrémité (18) et à exercer une pous
sée sur l'axe (16),par exemple en une pièce
de matière plastique enclipsée sur l'extré
mité (18)
à à son extrémité amont située à l'intérieur
du premier corps (11) des ailettes d'agita
tion (17), par exemple au nombre de deux ou
de trois.The advanced syringe consists
- a cylindrical piston (1) with a full body, for example of injected plastic such as polyethylene or other similar plastic, comprising upstream a support head (2) and downstream a needle (3) bearing seals (4) coming from molding, intended to ensure sealing;
- a cylindrical hollow compartment (5), forming a second body, also made of molded plastic of the same kind as the piston (1), intended to receive the second liquid (10), comprising at its upstream end atria (6) eC a stop and sealing stop (7), and at its downstream end
on the one hand, a thin waterproofing membrane
(8) intended to avoid the passage of the second
liquid (10) in the first body (11),
able to break under the effect of the push
exerted by the piston (1) on the liquid
(10); as an indication, this membrane
(8) can be any compatible film,
either glued to the downstream side, or obtained
directly during the molding of the second
body (5)
on the other hand, seals (9), identical to
to (4)
- A second cylindrical hollow compartment (11) forming the first body, of the same kind as (5), intended to receive the first liquid (12), and the total available volume of which is equal to the sum of the volumes of the two liquids (10 ) and (12) to be mixed; the second body (5) is able to move like a piston in this first body (11) which has
at its upstream end, ears of ap
pui (13) for injection and a stop
stop and sealing (14) similar to (7)
at its downstream end, a tapered cone (15)
reported, shown in detail in Figure 2
- An incorporated agitator assembly formed by a longitudinal axis (16) able to move in the first body (11) in a back and forth movement thanks to the structure detailed in Figure 2, and which has
at its downstream end (18) a button (19)
or any other equivalent means of prehens
sion, able to rotate freely around
this end (18) and to exert a push
placed on the axis (16), for example in one piece
plastic clipped onto the end
moth (18)
at at its upstream end located inside
the first body (11) of the agita fins
tion (17), for example two or
of three.
Le cone effilé (15) rapporté (voir figure 2) à l'extrémité du premier corps (11) présente une ouverture centrale (20) à l'intérieur de laquelle est ménagé un filetage en hélice (21). L'axe longitudinal (16) présente, sur une longueur sensiblement égale à celle du premier corps (11), un filetage extérieur en hélice (22) analogue à (21) et destiné à coopérer avec lui. The tapered cone (15) attached (see Figure 2) at the end of the first body (11) has a central opening (20) inside which is formed a helical thread (21). The longitudinal axis (16) has, over a length substantially equal to that of the first body (11), an external helical thread (22) similar to (21) and intended to cooperate with it.
En exerçant une poussée sur le bouton (19) dans le sens indiqué par la flèche F sur la figure 1, le bouton (19) comme dans une toupie, engage la rampe du filetage (22) dans la rampe du filetage (21), ce qui communique à l'axe (16) un mouvement de rotation sur lui-même et par voie de conséquence, déplace les ailettes (17) à l'intérieur du premier corps (11) dans un mouvement rotatif de translation longitudinale. En d'autres termes, on effectue une action de brassage. By pushing the button (19) in the direction indicated by the arrow F in FIG. 1, the button (19) as in a router, engages the thread ramp (22) in the thread ramp (21), which communicates to the axis (16) a rotational movement on itself and consequently, moves the fins (17) inside the first body (11) in a rotary movement of longitudinal translation. In other words, a stirring action is carried out.
Lorsque les ailettes (17) arrivent à l'extrémité amont du premier corps (11), l'opérateur retire alors le bouton (19) dans le sens indiqué par la flèche F' sur la figure 1, ce qui provoque alors une action de brassage inverse. Ainsi, à l'image d'une toupie, les ailettes (17) effectuent dans le premier corps (11) un mouvement rotatif de va et vient et par là homogénéisent le mélange contenu dans ce corps (11). When the fins (17) arrive at the upstream end of the first body (11), the operator then removes the button (19) in the direction indicated by the arrow F 'in FIG. 1, which then causes an action of reverse brewing. Thus, like a spinning top, the fins (17) perform in the first body (11) a rotary movement back and forth and thereby homogenize the mixture contained in this body (11).
Comme on le voit en détail sur les deux figures, l'extrémité amont (23) de l'axe (16) connectée aux ailettes (17) est creuse sur une partie légèrement plus longue que l'épaisseur du cône rapporté (15). En outre, la zone de séparation entre cette partie creuse (23) et la partie pleine (24) de l'axe longitudinal fileté extérieur (16), présente une amorce de rupture (25) obtenue également lors du moulage. As can be seen in detail in the two figures, the upstream end (23) of the axis (16) connected to the fins (17) is hollow over a part slightly longer than the thickness of the added cone (15). In addition, the separation zone between this hollow part (23) and the solid part (24) of the external threaded longitudinal axis (16) has a breaking point (25) also obtained during molding.
Une fois le mélange homogénéisé, il suffit d'exercer une simple poussée transversale sur l'axe (16) pour provoquer la cassure de cet axe (16) au niveau de l'amorce (25). Ainsi, par exemple, après avoir adapté une aiguille d'injection sur le cone effilé (15), on peut alors sous l'effet d'une poussée exercée sur le deuxième corps (5), agissant alors comme piston, injecter le mélange contenu dans le premier corps (11). Once the mixture is homogenized, it suffices to exert a simple transverse thrust on the axis (16) to cause the fracture of this axis (16) at the level of the primer (25). Thus, for example, after having adapted an injection needle on the tapered cone (15), it is then possible under the effect of a thrust exerted on the second body (5), then acting as a piston, to inject the contained mixture in the first body (11).
La mise en place des différents éléments s'effectue de la manière suivante. On place tout d'abord l'ensemble agitateur (16-17) dans l'ouverture (20) du premier corps (ll).CnIenclipse alors le bouton (19) sur l'extrémité aval (18). On remplit ensuite le corps (11) avec la quantité prévue de premier liquide (12). The installation of the various elements is carried out as follows. First place the agitator assembly (16-17) in the opening (20) of the first body (ll) .CnIenclipse then the button (19) on the downstream end (18). The body (11) is then filled with the expected quantity of first liquid (12).
Le volume total du corps (11) est égal à la somme des deux liquides (10) et (12). On introduit alors le deuxième corps (5) fermé par la membrane (8) dans le premier corps (11), puis on remplit le deuxième corps (5) et enfin on met le piston (1) enlace. L'ensemble est alors prêt à fonctionner et est placé dans un emballage éventuellement stérile.The total volume of the body (11) is equal to the sum of the two liquids (10) and (12). The second body (5) closed by the membrane (8) is then introduced into the first body (11), then the second body (5) is filled and finally the piston (1) is entwined. The assembly is then ready to operate and is placed in a possibly sterile packaging.
Lorsque l'on désire utiliser cet ensemble, il suffit à l'opérateur d'ouvrir l'emballage stérile, de pousser le piston (1) dans le deuxième corps (5), ce qui sous l'effet de la poussée, rompt la membrane (8) et amène alors le deuxième liquide (10) dans le corps (11) pour être mélangé avec le premier liquide (12). When it is desired to use this set, the operator need only open the sterile packaging, push the piston (1) into the second body (5), which under the effect of the push, breaks the membrane (8) and then brings the second liquid (10) into the body (11) to be mixed with the first liquid (12).
Une fois ce mélangeeffectué dans le corps (11), l'opérateur pousse sur le bouton (19) dans le sens alterné des flèches F et F'-, ce qui provoque l'agitation par les ailettes (17) qui se déplacent longitudinalement tout en tournant et donc homogénéisent le mélange. Une fois que cette homogénéisation est réalisée, l'opérateur dégage l'axe (16) du corps (11) et lorsque l'amorce (25) est sortie de l'ouverture (20), l'opérateur exerce ensuite une poussée transversale, ce qui casse l'axe (16) et ouvre ainsi le canal~(23). Le mélange contenu dans le corps (11) est alors prêt à être injecté sous l'effet d'une poussée exercée par l'ensemble piston (1)-deuxième corps (5). Once this mixing is carried out in the body (11), the operator pushes the button (19) in the alternating direction of the arrows F and F'-, which causes agitation by the fins (17) which move longitudinally while by turning and therefore homogenize the mixture. Once this homogenization is achieved, the operator releases the axis (16) from the body (11) and when the primer (25) is out of the opening (20), the operator then exerts a transverse thrust, which breaks the axis (16) and thus opens the channel ~ (23). The mixture contained in the body (11) is then ready to be injected under the effect of a thrust exerted by the piston (1) -second body (5) assembly.
Pour certaines applications,c#ù#il est souhaitable d'obtenir une étanchéité aussi parfaiteque possible, on ménage dans la surface interne inférieure (303 du cône rapporté (15) des entailles destinées à recevoir les ailettes (17). Ainsi, après avoir placé les ailettes (17) dans ces entailles, le fond de cette surface intérieure inférieure (30) peut être recouverte par un film qui est alors scellé sur ce fond de manière à assurer une étanchéité parfaite. Lors du premier mouvement aller de l'axe (16) dans la direction de la flèche F, ce film scellé sera aisément rompu. For certain applications, c # ù # it is desirable to obtain a seal as perfect as possible, there are notches in the lower internal surface (303 of the added cone (15) intended to receive the fins (17). placed the fins (17) in these notches, the bottom of this lower interior surface (30) can be covered by a film which is then sealed on this bottom so as to ensure a perfect seal. (16) in the direction of arrow F, this sealed film will be easily broken.
Cette seringue perfectionnée présente de nombreux avantages par rapport aux solutions actuelles. On peut citer
- le fait que l'ensemble soit en milieu parfaitement stérile, ce qui facilite son utilisation en milieu chirurgical
- le fait que l'ensemble soit prêt à l'usage, du fait que l'agitateur est incorporé à la seringue et qu'il n'y a donc pas lieu de faire appel à des éléments de manipulation extérieurs ;
- le fait que les dosages des deux liquides sont effectués préalablement
- enfin, la possibilité de réaliser sur place et en milieu parfaitement stérile, un mélange homogène.This improved syringe has many advantages over current solutions. We can cite
- the fact that the assembly is in a perfectly sterile environment, which facilitates its use in a surgical environment
- the fact that the assembly is ready for use, due to the fact that the agitator is incorporated into the syringe and that there is therefore no need to call on external handling elements;
- the fact that the dosages of the two liquids are carried out beforehand
- finally, the possibility of producing a homogeneous mixture on site and in a perfectly sterile environment.
De la sorte, ce type de seringue peut être utilisé avec succès pour le mélange de tout produit à deux composants nécessitant une homogénéisation, notamment en milieu stérile. A titre d'exemple, on peut citer l'utilisation en milieu médical, en art dentaire, en chirurgie, en chimie tels que le mélange de résine ou de colle In this way, this type of syringe can be successfully used for mixing any product with two components requiring homogenization, especially in a sterile environment. By way of example, mention may be made of use in the medical environment, in dentistry, in surgery, in chemistry such as the mixture of resin or glue.
