Description

APPAREIL DE DESTRUCTION D'AIGUILLES D'INJECTION ET PROCEDE. APPARATUS FOR DESTRUCTION OF INJECTION NEEDLES AND METHOD.
L'invention concerne un appareil destructeur d'aiguilles d'injection telles que celles utilisées pour l'injection au travers de la peau ou de la muqueuse buccale de produits contenus dans des seringues réutilisables, et un procédé de destruction d'une aiguille montée sur un corps de seringue réutilisable.The invention relates to an apparatus for destroying injection needles such as those used for injecting through the skin or the oral mucosa products contained in reusable syringes, and a method for destroying a needle mounted on a reusable syringe body.
Une aiguille d'injection comporte une embase de montage sur un corps de seringue et une tige creuse solidaire de l'embase. Lors de la manipulation d'une aiguille de ce type, l'utilisateur est tenu de respecter des règles d'hygiène limitant les risques de propagation de certaines maladies. En particulier, l'aiguille d'injection doit être éliminée après sa première utilisation sans qu'il soit nécessaire de la saisir avec les doigts afin d'éviter le risque pour l'utilisateur de se piquer avec une aiguille souillée. Lorsque l'aiguille est destinée à être montée sur un corps de seringue réutilisable dans lequel est montée une cartouche fermée par un opercule, l'embase de l'aiguille comporte un canal dans lequel s'étend la tige creuse qui est solidaire d'une extrémité de l'embase de sorte que l'opercule de la cartouche est traversée par la partie interne de la tige creuse lors de la mise en place de l'aiguille sur le corps de seringue.An injection needle has a mounting base on a syringe body and a hollow rod secured to the base. When handling a needle of this type, the user is required to comply with hygiene rules limiting the risk of the spread of certain diseases. In particular, the injection needle must be eliminated after its first use without it being necessary to grasp it with the fingers in order to avoid the risk for the user of pricking himself with a dirty needle. When the needle is intended to be mounted on a reusable syringe body in which is mounted a cartridge closed by a cover, the base of the needle comprises a channel in which extends the hollow rod which is integral with a end of the base so that the cover of the cartridge is crossed by the internal part of the hollow rod when the needle is placed on the syringe body.
On connaît, notamment du document WO 84/04068 et des documents américains 4,404,881, 4,275,628 et 4,565,311, des appareils destructeurs d'aiguilles montées sur des corps de seringues jetables, ces appareils comprenant des moyens de découpe destinés à sectionner la tige creuse de l'aiguille et l'extrémité du corps de seringue. Le sectionnement de la tige creuse de l'aiguille provoque une usure rapide des moyens de découpe et le sectionnement du corps de seringue n'est pas envisageable pour un corps de seringue réutilisable. Les appareils décrits dans ces documents ne sont donc pas exploitables en relation avec des corps de seringue réutilisables. Selon l'invention on propose un appareil destructeur d'aiguille comprenant un bâti portant un moyen de découpe comportant deux mâchoires ayant chacune une arête coupante, un organe de manoeuvre pour provoquer le coulis- sèment d'au moins une des mâchoires vers l'autre, les mâchoires étant disposées au repos de telle sorte que les arêtes coupantes définissent une ouverture d'introduction de l'aiguille, et des moyens pour limiter le coulissement des mâchoires dans une position où les arêtes coupantes définissent une ouverture inférieure à l'ouverture d'introduction.Are known, in particular from document WO 84/04068 and American documents 4,404,881, 4,275,628 and 4,565,311, devices destructive of needles mounted on bodies of disposable syringes, these devices comprising cutting means intended to cut the hollow stem of the needle and the end of the syringe body. The cutting of the hollow rod of the needle causes rapid wear of the cutting means and the cutting of the syringe body is not possible for a reusable syringe body. The devices described in these documents cannot therefore be used in relation to reusable syringe bodies. According to the invention there is provided a needle destructor comprising a frame carrying a cutting means comprising two jaws each having a cutting edge, an operating member for causing the sliding of at least one of the jaws towards the other , the jaws being arranged at rest so that the cutting edges define an opening for introducing the needle, and means for limiting the sliding of the jaws in a position where the cutting edges define an opening smaller than the opening d 'introduction.
Ainsi, par un positionnement de la seringue pour que l'embase de l'aiguille vienne en regard du moyen de découpe et une manoeuvre de celui-ci on assure le section- nement de l'embase sans sectionner la tige creuse de sorte que celle-ci se trouve désolidarisée de l'embase et peut être récupérée en totalité dans un récipient.Thus, by positioning the syringe so that the base of the needle comes opposite the cutting means and an operation of this one ensures the cutting of the base without cutting the hollow rod so that -this is separated from the base and can be recovered entirely in a container.
Selon une version avantageuse de l'invention l'aiguille comporte une embase comprenant un canal ayant un diamètre supérieur à un diamètre de la tige creuse s 'étendant dans le canal de l'embase et l'appareil comporte un organe de butée disposé pour que le moyen de découpe sectionne l'embase à distance de l'extrémité dont la tige est solidaire. Ainsi le positionnement de l'embase en regard du moyen de découpe est facilement réalisé.According to an advantageous version of the invention the needle comprises a base comprising a channel having a diameter greater than a diameter of the hollow rod extending in the channel of the base and the apparatus comprises a stop member arranged so that the cutting means cuts the base away from the end of which the rod is integral. Thus the positioning of the base opposite the cutting means is easily achieved.
De préférence le coulissement est limité lors de la fermeture des mâchoires de façon qu'après coulissement les dimensions de l'ouverture soient supérieures au diamètre de la tige. Ainsi les arêtes coupantes des mâchoires ne viennent pas en contact de la tige creuse, de sorte que l'on minimise l'usure des arêtes coupantes des mâchoires .Preferably the sliding is limited during the closing of the jaws so that after sliding the dimensions of the opening are greater than the diameter of the rod. Thus the cutting edges of the jaws do not come into contact with the hollow rod, so that wear of the cutting edges of the jaws is minimized.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention, en relation avec les figures ci-jointes parmi lesquelles :Other characteristics and advantages of the invention will appear on reading the following description of a particular non-limiting embodiment of the invention, in relation to the attached figures among which:
- la figure 1 est une vue en perspective en coupe partielle de l'appareil destructeur d'aiguilles selon l'invention,FIG. 1 is a perspective view in partial section of the device for destroying needles according to the invention,
- la figure 2 est une vue partielle en coupe du moyen de découpe dans une position de repos, selon la ligne II-II de la figure 1,FIG. 2 is a partial sectional view of the cutting means in a rest position, along the line II-II of FIG. 1,
- la figure 3 est une vue partielle de dessus de l'appareil selon l'invention,FIG. 3 is a partial top view of the device according to the invention,
- la figure 4 est une vue partielle du moyen de découpe selon une coupe analogue à celle de la figure 2 dans une position de sectionnement.- Figure 4 is a partial view of the cutting means in a section similar to that of Figure 2 in a sectioning position.
En référence aux figures, l'appareil selon l'invention comporte un bâti 1 représenté sous la forme d'un carter enveloppant.With reference to the figures, the apparatus according to the invention comprises a frame 1 represented in the form of an enveloping casing.
Un organe de butée 2 formé ici par une partie du carter enveloppant est solidaire du bâti 1 et comporte un orifice 3 en forme de U dont les dimensions permettent le passage de l'aiguille tout en assurant un appui pour un corps de seringue. Un ensemble photo-électrique, constitué d'une cellule réceptrice 4 et d'une cellule émettrice 5, est disposé au-dessus de l'orifice 3.A stop member 2 formed here by a part of the enveloping casing is integral with the frame 1 and has an orifice 3 in the shape of a U whose dimensions allow the passage of the needle while ensuring support for a syringe body. A photoelectric assembly, consisting of a receiving cell 4 and a transmitting cell 5, is disposed above the orifice 3.
Un moyen de découpe, généralement désigné en 6, est disposé à l'aplomb de l'orifice 3 en dessous de celui- ci. Le moyen de découpe 6 comporte une mâchoire fixe 7 solidaire du bâti 1 et une mâchoire mobile 8 reçue à coulissement par le bâti 1. Chacune des deux mâchoires 7 et 8 comprend une arête coupante concave en forme de V disposée sensiblement en regard de l'arête coupante de l'autre mâchoire. Les mâchoires 7 et 8 se chevauchent partiellement et sont disposées de telle sorte que leurs arêtes coupantes définissent une ouverture d' introduction 18 de l'aiguille en regard de l'orifice 3. La mâchoire mobile 8 est solidaire de la tige d'un vérin électrique généralement désigné en 9, formant un organe de manoeuvre porté par le bâti 1. Le vérin 9 est alimenté par un circuit électrique non représenté pour lequel l'ensemble photoélectrique forme un interrupteur. Un récipient de récupération 10 comprenant un orifice 11 de faibles dimensions est reçu élastiquement et de manière amovible par le bâti 1. Le récipient de récupération 10 est disposé de sorte que l'orifice 11 soit en regard de l'ouverture d'introduction 18. Dans le cas représenté aux figures 2 et 4, l'aiguille 12 qu'il s'agit de détruire, comporte une embase 13 et une tige 14 creuse solidaire de l'extrémité de l'embase 13 par l'intermédiaire d'un point de colle 15. La tige 14 s'étend de part et d'autre de l'embase 13 dans un canal 16 de diamètre supérieur à celui de la tige 14. L'embase 13 est montée sur un corps de seringue 17. Une partie de la tige 14 s'étend alors dans le corps de seringue 17 et traverse l'opercule plastique obturant la cartouche, non représentée, contenant le produit à injec- ter.A cutting means, generally designated at 6, is arranged directly above the orifice 3 below the latter. The cutting means 6 comprises a fixed jaw 7 integral with the frame 1 and a movable jaw 8 slidably received by the frame 1. Each of the two jaws 7 and 8 comprises a concave V-shaped cutting edge disposed substantially opposite the cutting edge of the other jaw. The jaws 7 and 8 partially overlap and are arranged so that their cutting edges define an insertion opening 18 of the needle opposite the orifice 3. The movable jaw 8 is integral with the rod of a jack electric generally designated at 9, forming an operating member carried by the frame 1. The jack 9 is supplied by an electrical circuit, not shown, for which the photoelectric assembly forms a switch. A recovery container 10 comprising an orifice 11 of small dimensions is resiliently and removably received by the frame 1. The recovery container 10 is arranged so that the orifice 11 faces the introduction opening 18. In the case shown in Figures 2 and 4, the needle 12 to be destroyed, has a base 13 and a hollow rod 14 secured to the end of the base 13 via a point of glue 15. The rod 14 extends on either side of the base 13 in a channel 16 of diameter greater than that of the rod 14. The base 13 is mounted on a syringe body 17. A portion of the rod 14 then extends into the syringe body 17 and passes through the plastic cover sealing the cartridge, not shown, containing the product to be injected.
En fonctionnement, le moyen de découpe 6 se trouvant dans une position de repos telle que représentée à la figure 2, l'utilisateur engage l'aiguille 12, montée sur le corps de seringue 17, au travers de l'orifice 3 et de l'ouverture d'introduction 18 jusqu'à ce que le corps de seringue 17 soit en appui sur l'organe de butée 2 de sorte que l'extrémité de l'embase 13 se trouve engagée au-delà des arêtes coupantes du moyen de découpe 6, sous celui-ci.In operation, the cutting means 6 being in a rest position as shown in Figure 2, the user engages the needle 12, mounted on the syringe body 17, through the orifice 3 and the insertion opening 18 until the syringe body 17 is in abutment on the stop member 2 so that the end of the base 13 is engaged beyond the cutting edges of the cutting means 6, under this one.
Le corps de seringue 17 coupant le faisceau lumineux émis par la cellule 5 vers la cellule 4 provoque l' actionnement du vérin 9. Le vérin 9 fait alors coulisser la mâchoire mobile 8 vers la mâchoire fixe 7. L'aiguille 12 est de ce fait poussée par la mâchoire mobile 8 vers la mâchoire fixe 7. L'ouverture 18 se rétrécit de telle façon que l'embase 13 soit prisonnière des arêtes coupantes. Le coulissement se poursuit jusqu'à ce que les parois du canal 16 de l'embase 13 soient découpées par l'action des arêtes coupantes . La course de la tige du vérin 9 est prévue pour que le coulissement soit interrompu alors que les dimen- sions de l'ouverture 18 restent supérieures au diamètre de la tige 14. On évite ainsi que les arêtes coupantes des mâchoires de découpe viennent au contact de la tige et soient abîmées par celle-ci.The syringe body 17 cutting the light beam emitted by cell 5 towards cell 4 causes actuation of the jack 9. The jack 9 then slides the movable jaw 8 towards the fixed jaw 7. The needle 12 is therefore pushed by the movable jaw 8 towards the fixed jaw 7. The opening 18 narrows so that the base 13 is trapped in the cutting edges. The sliding continues until the walls of the channel 16 of the base 13 are cut by the action of the cutting edges. The stroke of the rod of the jack 9 is provided so that the sliding is interrupted while the dimensions of the opening 18 remain greater than the diameter of the rod 14. This avoids the cutting edges of the cutting jaws coming into contact of the stem and are damaged by it.
Après coulissement (voir plus particulièrement la figure 4) , la tige 14 reste donc entière tandis que l'embase 13 est divisée en une première partie 13.1 dont la tige 14 demeure solidaire, et une seconde partie 13.2 solidaire du corps de seringue 17.After sliding (see more particularly FIG. 4), the rod 14 therefore remains entire while the base 13 is divided into a first part 13.1 whose rod 14 remains integral, and a second part 13.2 integral with the syringe body 17.
Un signal, sonore ou lumineux, annonçant la fin du coulissement, prévient l'utilisateur qu'il peut retirer le corps de seringue 17 de l'appareil destructeur. Il dégage ainsi la tige 14 de l'opercule plastique, la tige étant maintenue dans l'appareil par la partie 13.1, dont elle est solidaire, retenue par les mâchoires 7 et 8. la partie 13.1 de l'embase et la tige 14 tombent alors dans le récipient de récupération 10 par l'orifice 11. Le retrait du corps de seringue 17 rétablit le faisceau lumineux entre les cellules 5 et 4, ce qui provoque le retour en position de repos du moyen de découpe 6, après un certain délai permettant la retenue de la partie 13.1 de l'embase par les mâchoires pendant le désengagement de la tige 14 de l'opercule plastique.A signal, audible or luminous, announcing the end of the sliding, warns the user that he can withdraw the syringe body 17 from the destructive apparatus. It thus releases the rod 14 from the plastic cover, the rod being held in the apparatus by the part 13.1, of which it is integral, retained by the jaws 7 and 8. the part 13.1 of the base and the rod 14 fall then in the recovery container 10 through the orifice 11. The withdrawal of the syringe body 17 restores the light beam between the cells 5 and 4, which causes the cutting means 6 to return to the rest position, after a certain delay allowing the retention of the part 13.1 of the base by the jaws during the disengagement of the rod 14 from the plastic cover.
L'utilisateur n'a alors plus qu'à démonter la partie 13.2 du corps de seringue 17 et la jeter avec la cartouche qui contenait le produit à injecterThe user then only has to dismantle the part 13.2 of the syringe body 17 and discard it with the cartridge which contained the product to be injected
Bien entendu l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications . En particulier, bien que l'invention ait été décrite en relation avec des aiguilles dont la tige s'étend de part et d'autre de l'embase, l'appareil selon l'invention peut être aisément utilisé avec des aiguilles classiques, le moyen de découpe sectionnant alors soit une partie du corps de seringue soit une partie de l'embase. L'aiguille tombera alors dans le récipient de récupération immédiatement après la découpe.Of course, the invention is not limited to the embodiment described and it is possible to make variant embodiments without departing from the scope of the invention as defined by the claims. In particular, although the invention was described in relation to needles whose rod extends on either side of the base, the device according to the invention can be easily used with conventional needles, the cutting means then cutting either a part of the body syringe or part of the base. The needle will then fall into the recovery container immediately after cutting.
Bien que le moyen de découpe ait été représenté fixe par rapport à l'organe de butée, on pourrait monter le moyen de découpe sur une platine mobile par rapport à l'organe de butée permettant d'écarter le moyen de découpe de l'organe de butée pour faire tomber automatiquement la tige dans le récipient de récupération.Although the cutting means has been shown to be fixed relative to the stop member, the cutting means could be mounted on a plate movable relative to the stop member making it possible to separate the cutting means from the member. stopper to automatically drop the rod into the recovery container.
Bien que l'organe de manoeuvre ait été représenté sous la forme d'un vérin électrique, il pourrait être réalisé sous la forme d'un moteur rotatif portant une roue dentée coopérant avec une crémaillère solidaire de la mâchoire mobile .Although the operating member has been shown in the form of an electric actuator, it could be produced in the form of a rotary motor carrying a toothed wheel cooperating with a rack integral with the movable jaw.
Bien qu'une seule mâchoire ait été représentée mobile, les deux peuvent l'être, de même que plus de deux mâchoires peuvent être utilisées.Although only one jaw has been shown to be movable, both can be shown, just as more than two jaws can be used.
Bien qu'un ensemble photo-électrique soit utilisé pour détecter la présence du corps de seringue, on peut utiliser un capteur de fin de course classique. Although a photoelectric assembly is used to detect the presence of the syringe body, a conventional limit switch can be used.
