Abstract

The end-piece (1) of the syringe is continued and centred by a sleeve (3) which can be compressed via an oval notch (2). The end-piece (4) of the needle covers the distal part (5) of the end-piece hermetically. If the sleeve (3) is collapsed, the traction on the end-piece (1), which is withdrawn slightly from the base (4) of the needle, results in the suction of a volume of blood if operating in an artery. The whole device being transparent.

Description

Dispositif universel.pour seringues médicales detous types et de toutes contenances,en matière plastique à usage unique non rêutilisables,permettant l'aspiration de contrôle (aprés plantation de l'aiguille)avant de commencer llin-jection,ceci afin d'éviter l'injection intempestive dans une artère. Universal device. For medical syringes of all types and all capacities, made of single-use plastic material, which cannot be reused, allowing control aspiration (after planting the needle) before starting the injection, in order to avoid untimely injection into an artery.

Jusqu'à présent les modèles de seringues médicales non réutilisables proposés ne permettent pas cette aspiration de sécurité qui est éxigée par exemple par l'organisation mondiale de la santé(O.M.S)sauf pour les petites seringues de 0,5mol environ.Ceci est un critère qui écarte de nombreux modèles de seringues,par ailleurs performants,mais dont le principe de neutralisation est justement d'interdire une deuxième aspiration par traction sur le manche du piston. Until now, the models of non-reusable medical syringes offered do not allow this safety aspiration, which is required, for example, by the World Health Organization (WHO), except for small syringes of around 0.5mol. This is a criterion which excludes many models of syringes, which are also efficient, but whose neutralization principle is precisely to prohibit a second aspiration by traction on the handle of the piston.

Le dispositif universel selon l'invention permet de résoudre le problème trés simplement,ut à moindre coût. The universal device according to the invention makes it possible to solve the problem very simply, ut at a lower cost.

L'étude est faite sur une seringue en position horizontale aiguille pointant vers la droite. The study is done on a syringe in horizontal position needle pointing to the right.

Dans la seringue équipée du dispositif selon l'invention l'embout,transparent,est plus long et comporte une large ouverture ovalaire à grand axe longitudinal et à petit axe transversal.Cette ouverture intéresse l'embout sur un peu plus de la moitié de son épaisseur.Un trait coloré est situé sur le corps de la serîngue,dans l'axe de l'ouverture ovalaire et facilite l'orientation. In the syringe equipped with the device according to the invention, the transparent tip is longer and has a large oval opening with a large longitudinal axis and a small transverse axis. This opening interests the tip over a little more than half of its thickness.A colored line is located on the body of the seringue, in the axis of the oval opening and facilitates orientation.

La lumière de l'embout est plus large que dans les seringues classiques mais son extrémité gauche(proximale pour le manipulateur),communiquant avec la chambre de la seringue, est barrée par une surface plane percée d'un petit trou. The lumen of the nozzle is wider than in conventional syringes but its left end (proximal for the manipulator), communicating with the syringe chamber, is barred by a flat surface pierced with a small hole.

L'extrémité droite(distale pour le manipulateur)a un orifice un peu retréci par un petit liseré convexe circonférentiel (convexité interne).The right end (distal for the manipulator) has a slightly narrowed orifice with a small convex circumferential border (internal convexity).

A l'inbérieur de l'embout est glissé un petit manchon, en matière plastique transparente et assez souple,qui occupe toute la longueur de l'embout. Inside the end piece is slipped a small sleeve, made of transparent and fairly flexible plastic, which occupies the entire length of the end piece.

Son passage est visible par I 'ouverture ovalaire ajourant 1 'embout. Le liseré distal lui sert de frein et empêche sa sortie intempestive.La lumière du manchon, assez fine, correspond au diamétre du trou de communication avec la chambre de la seringue.Ainsi,la quantité de liquide contenue dans le manchon est trés négligeable.Le manchon est dépressible par la pression d'un doigt mais il n'est pas expansible car ses parois sont assez epaisses.Il ne bombera donc pas ultérieurement,lors de l'injection. Its passage is visible through the oval opening perforating the end piece. The distal border serves as a brake and prevents its untimely exit. The light of the sleeve, rather fine, corresponds to the diameter of the hole for communication with the chamber of the syringe. Thus, the quantity of liquid contained in the sleeve is very negligible. sleeve is depressible by the pressure of a finger but it is not expandable because its walls are quite thick. It will therefore not bulge later, during the injection.

L ! embase de l'aiguille est transparente et plus longue que dans les #ingues classiques.Son intérieur est cylindrique et reçoit,herm#iquement,la partie distale de l'embout,jusqu'à l'ouverture ovalaire, qui n'est pas concernée. L! base of the needle is transparent and longer than in conventional #ingues.Its interior is cylindrical and receives, herm # ically, the distal part of the tip, up to the oval opening, which is not concerned .

Ainshune fois la seringue non réutilisable remplie, ajustée, et prête pour l'injection, l'aiguille est plantée,mais la seringue est inapte à toute aspiration par traction sur le manche. Once the non-reusable syringe is filled, adjusted, and ready for injection, the needle is planted, but the syringe is not suitable for any aspiration by pulling on the handle.

Grâce au dispositif selon 1 'invention,le manipulateur peut vérifier s'il n'est pasdans une artère en procédant de la manière suivante: (par exemple).Thanks to the device according to the invention, the manipulator can check if it is not in an artery by proceeding as follows: (for example).

- Ilpince l'embase de l'aiguille entre le pouce et l'index de la min droite. - He pinches the base of the needle between the thumb and the index finger of the right min.

- Pus,avec le pouce de la main gauche, il appuie,à travers l'ouverte ovalaire de# l'embout,sur le manchon, et le collabe.Il est à remarquer que cette pression ne représente pas une injection car le manchon à des parois compressibles qui amortissent la poussée due à l'infime quantité de liquide dépla- crée.  - Pus, with the thumb of the left hand, it presses, through the oval opening of the # tip, on the sleeve, and the collab. It should be noted that this pressure does not represent an injection because the sleeve has compressible walls which absorb the thrust due to the minute quantity of displaced liquid.

- Puis il retire l'embout(de quelques millimétres)de l'embase de l'aiguille.Ici l'embout joue de rôle d'un piston tandis que l'embase joue le rôle d'un corps de seringue
- Interprétation du résultat de l'opération
- Si le manipulateur voit apparaitre un petit volute de s-ang qui remonte dans l'embout,il saura qu'il est dans une artèr#. Il ne doit pas injecter à ce ni veau. il doit replacer l'embout à fond dans l'embase de l'aiguille après avoir cessé de comprimer le manchon avec son pouce gauche.- Then he removes the tip (a few millimeters) from the base of the needle. Here the tip plays the role of a piston while the base plays the role of a syringe body.
- Interpretation of the transaction result
- If the manipulator sees a small volute of s-ang appearing which goes up in the nozzle, it will know that it is in an artery #. He should not inject this nor calf. he must replace the end piece fully in the base of the needle after having stopped compressing the sleeve with his left thumb.

- Si,par contre,il ne voit pas de sang apparaitre dans l'embout,il met fin à la pression de son pouce gauche sur le manchon,replace l'embout à fond dans l'embase de 1'aiguille;et procéde à l'injection par poussée sur le manche du piston de la seringue. - If, on the other hand, he does not see blood appearing in the tip, he puts an end to the pressure of his left thumb on the sleeve, places the tip fully back in the base of the needle; and proceeds to push injection on the syringe plunger handle.

La lumière du manchon étant fine,la quantité de liquide qui y reste est tout à fait négligeable. Ainsi ,le dispositif selon l'invention ne permet pas l'injection par le simple mouvement de l'embout dans l'embase de l'aiguille. The lumen of the sleeve being fine, the quantity of liquid which remains there is completely negligible. Thus, the device according to the invention does not allow injection by the simple movement of the tip into the base of the needle.

Le mode de réalisation étudié ci-dessus est conçu pour les liquides même trés visqueux.Cependant, un mode de réalisation selon une variante plus simple,donnant une seringue plus maniable,peut être réalisé.Il consiste en un embout de seringue prolongé,à fine lumière prolongeant la lumière de l'aiguille, sans manchon et sans ouverture ovalaire.Cet embout sera coiffé de manière assez serrée,donc hermétiquement,sur toute sa longueur,par l'embase également prolongée de 1 'aiguille.Le manipulateur saisit l'embase de l'aiguille entre deux doigts d'une main et retire légérement la seringue qu'il tient dans la paume de l' autre main. L ' apparit~ on d'un volute de sang montre que l'aiguille est dans une artère. The embodiment studied above is designed for liquids even very viscous. However, an embodiment according to a simpler variant, giving a more manageable syringe, can be realized. It consists of an extended syringe tip, fine lumen extending the lumen of the needle, without sleeve and without oval opening. This endpiece will be capped in a fairly tight manner, therefore hermetically, over its entire length, by the base also extended by the needle. The manipulator grasps the base of the needle between two fingers with one hand and lightly withdraws the syringe which it holds in the palm of the other hand. The appearance of a volute of blood shows that the needle is in an artery.

Le dispositif selon l'invention est absolument universel car tous les modéles de 'seringues médicales non réutilisables sont interessés,quelque soit leur diamétre ou leur contenance, et quelque soit le mécanisme de neutralisation qu'ils mettent en jeu.De multiples variantes de taille et de format peuvent être étudiées sans sortir du champ de l'invention. The device according to the invention is absolutely universal because all the models of non-reusable medical syringes are of interest, whatever their diameter or their capacity, and whatever the neutralization mechanism that they bring into play. format can be studied without departing from the scope of the invention.

La figure 1 montre une vue d'ensemble d'une seringue équipée du dispositif selon l'invention.L'embout prolongé(1)est ajouré d'une ouverture ovala:ire(2)qui laisse apparaitre le manchon en matière plastique souple( 4.t'embase(4)de l'aiguille est plus longue que dans les seringues classiques.  Figure 1 shows an overview of a syringe equipped with the device according to the invention. The extended tip (1) is perforated with an oval opening: ire (2) which reveals the flexible plastic sleeve ( 4.the needle base (4) is longer than in conventional syringes.

La figure 2 montre l'embout séparé de l'embase(4)de l'aiguille.La partie distale(5) de cet embout est assez longue et de forme cylindrique. Figure 2 shows the tip separate from the base (4) of the needle. The distal part (5) of this tip is quite long and cylindrical in shape.

La figure 3 montre que le manchon en matière plastique. Figure 3 shows that the plastic sleeve.

souple (3)a été retiré par traction freinée par le petit liseré convexe circonferentiel(6)situé à l'extrémité de l'embout.flexible (3) was removed by braked traction by the small convex circumferential border (6) located at the end of the end piece.

La figure 4 montre une coupe longitudinale médiane du dispositif,avec l'orifice de sortie(#)retréci de la chambre(8) de la seringue.L'embase(4)serre hermétiquement la partie distale cylindrique de- l'embout.  Figure 4 shows a median longitudinal section of the device, with the outlet orifice (#) narrowed from the chamber (8) of the syringe. The base (4) hermetically seals the cylindrical distal part of the nozzle.

La figure 5(seringue remplie 7 aiguille plantée)montre l'index et le pouce de la main droite du manipulateur saisissant i 'embase de l'aiguille.  Figure 5 (syringe filled 7 needle planted) shows the index finger and thumb of the manipulator's right hand grabbing the base of the needle.

La figure 6 montre que le manipulateur collabe le manchon (3)avec son pouce gauche et retire un peu l'embout.Ici il ne doit pas injecter car il est dans une artère comme le prouve l'apparition du volume de sang(9).Il doit relâcher le manchon (3),remettre l'embout(l)au fond de l'embase(4)et retirer l'aiguille. Figure 6 shows that the manipulator collabates the sleeve (3) with his left thumb and slightly withdraws the tip. Here he must not inject because it is in an artery as the appearance of the volume of blood proves (9) .It must release the sleeve (3), put the end piece (l) back into the base (4) and withdraw the needle.

La figure 7 montre la forme de réalisation selon une variante plus simple et plus maniable.Ici l'embout(lO)est à lumière fine prolongeant la lumière de l'aiguille.L'embase(11) est assez serrée sur cet embout qu'elle recouvre donc hermétiquement sur toute sa longueur.Ici le volume(12)de sang, lors de l'aspiration,prouve que le manipulateur est dans une artère.Iî ne doit pas in#ecter.Dans le cercle en pointillés on voit le dispositif à l'état initial.  FIG. 7 shows the embodiment according to a simpler and more manageable variant. Here the end piece (10) is in fine light extending the lumen of the needle. The base (11) is fairly tight on this end piece as it therefore hermetically covers its entire length. Here the volume (12) of blood, during aspiration, proves that the manipulator is in an artery. It must not in #ect. In the dotted circle we see the device in the initial state.
