Abstract

The invention relates to an injection syringe, in particular for hypodermic injections. On the threaded rod 4 of the piston 3, the threaded ring 13 comprises an internal click jumping from one of the four grooves 12 to another when the ring is unscrewed. The click stops it being screwed in. If the wall 16 is smooth, injection is carried out by pushing on the head 5. If it is threaded and has a click, injection is performed by screwing the rod 4 into the annulus 6. Application: injection of the contents of the body 2, in several successive precise doses. <IMAGE>

ple , au nombre de quatre . ple, four in number. Sur ce filetage est vissée une bague 13 formant écrou , pourvue d'au moins un cliquet élastique intérieur 14 (figures 8 à 10) . On this thread is screwed a ring 13 forming a nut, provided with at least one resilient pawl 14 inside (Figures 8 to 10). De plus ,elle comporte un repère extérieur 15 t disposé en relief Furthermore, it comprises an external reference 15t arranged in relief
La couronne 6 des figures 1 à 10 ba une paroi intérieure 16 lisse (figure 1) , dans laquelle peut coulisser librement la tige filetée 4 .De plus , un doigt intérieur 17 dépasse sur l'intérieur de la paroi 16 , dans l'une des rainures longitudinales 12 t ce qui interdit a la tige 4 du piston 3 , de tourner dans la couronne 6 The crown 6 of Figures 1 to 10 b has a smooth inner wall 16 (Figure 1) in which can slide freely the threaded rod 4 .From addition, an inner finger 17 than on the inside of the wall 16 in one longitudinal grooves 12 t which prevents a rod 4 of the piston 3 to rotate in the ring 6
Enfin , un repère extérieur 18 est prévu en relief sur la couronne 6 . Finally, an external reference 18 is provided in relief on the crown 6. Ce relief 18 peut autre réalisé avec le doigt 17 t sous la forme d'une unique pièce 17-18 démontable ( figures 6 et 7) t ou bien être simplement moulu en relief , d'une pièce avec la couronne 6. This relief 18 may further carried out with the finger 17 t in the form of a single piece removable 17-18 (Figures 6 and 7) t or simply be ground in relief in one piece with the crown 6.

Le fonctionnement est le suivant The operation is as follows
On voit , sur les figures 2 à 4 , que la présentation de l'aiguille 10 ( figure 2) t la perforation de la membrane stérile 19 ( figure 3) , par vissage de 1' embout 9 t et l'extraction de l'étui d'emballage stérile 20 (figure 4) , s4effectuent sans qu'à aucun moment t l'aiguille 10 ne risque d'être contaminée par un quelconque contact non stérile. One sees in Figures 2 to 4, that the presentation of the needle 10 (Figure 2) t perforation of the sterile membrane 19 (Figure 3), by screwing one nozzle 9 t and extraction of the sterile carrier sleeve 20 (Figure 4), s4effectuent without at any time t the needle 10 not likely to be contaminated by any non-sterile contact.

Ensuite 2 il suffit à l'utilisateur de dévisser la bague 13 (figure 5) , d'une quantité repérée qui correspond exactement à la dose de produit que doit injecter le piston 3 . 2 then it suffices for the user to unscrew the ring 13 (Figure 5), a marked amount which exactly corresponds to the dose to be injected the piston 3. Ce dévissqge est repéré exactement: This dévissqge is spotted exactly:
- d'une part , visuellement t par simple observation du - firstly, visually by simply observing the t
décalage des repères 15 ( sur la bague 13) et 18 ( sur shifting of pins 15 (of the ring 13) and 18 (on
la couronne 6) the crown 6)
- d'autre part , de façon tactile et auditive t par per - secondly, tactile and auditory way t per
ception de chaque passage sur une rainure 12 , d'un receipt of each pass over a groove 12, a
cliquet élastique 21 dont est pourvue la paroi interne resilient pawl 21 which is provided with the inner wall
de la bague 13. of the ring 13.

On peut améliorer encore la précision du repérage tactile ou visuel t en répartissant régulièrement huit encoches 22 sur la priphérie de la bague 13. We can still improve the accuracy of visual or tactile identification t distributing regular eight notches 22 on priphérie of the ring 13.

On voit que le cliquet 21 permet de librement dévisser la bague 13 sur la tige filetée 4 ( rotation dans le sens de la flèche 23) , alors qu'il n'est pas pos sible de la visser (flèche 24 , figure 10). It is seen that the pawl 21 can be freely unscrew the ring 13 on the threaded rod 4 (rotation in the direction of the arrow 23), whereas it is not pos sible to screw (arrow 24, Figure 10).

La bague 13 étant ainsi immobilisée sur la tige 4 , à une distance 25 exactement calibrée ( figure 11) , il suffit dtcnf9ncer le poussoir 5 , par une pression du pouce 26 (figure 12) t pour injecter très exac toment la dose voulue du produit contenu dans le corps tubulaire 2 . The ring 13 is thus immobilized on the rod 4, at a distance 25 accurately calibrated (Figure 11), just dtcnf9ncer the pusher 5, by thumb pressure 26 (Figure 12) t for injecting very ExAC toment product desired dose contained in the tubular body 2. L'injection se poursuit jusqutà ce que la bague 13 vienne à nouveau buter contre la couronne 6 .La seringue est alors prête pour une autre injection & pratiquer ultérieurement par un nouveau réglage de la bague 13 t mulon dévisse comme indiqué sur le s figures 8 et 9. Injection continues jusqutà that the ring 13 comes again into abutment against the ring 6 .The syringe is then ready for another injection & later practice by a new setting of the ring 13 t mulon unscrewed as shown in Figures 8 s and 9.

Dans la variante des figures 13 à 19 l'intérieur de la couronne 6 est t lui aussi , fileté et muni d'au moins un cliquet 27 t qui coopère avec les rainures 12 . In the variant of Figures 13-19 inside the ring 6 is t also, threaded and provided with at least one pawl 27 t which cooperates with the grooves 12. Ce cliquet 27 est orienté de façon à permettre librement le vissage de la tige 4 dans le sens de la flèche 28 i figure 16) t qui provoque l'enfoncement du piston 3 dans le corps 2 . This pawl 27 is oriented so as to freely allow screwing of the rod 4 in the direction of arrow 28 i Figure 16) t which causes depression of the piston 3 in the body 2. Au contraire A il interdit tout recul du piston 3 ( dévissage dans le sens de la flèche 29 ( figure 15). To the contrary it prohibits withdrawal of piston 3 (unscrewing in the direction of the arrow 29 (Figure 15).

En ce qui concerne la bague 13 9 on l'a équipée de deux cliquets intérieurs 21 et 30 t décalés an gulairement d'un nombre impa de huitièmes de tour ((2n + 1).45 degrés g où n est un nombre entier compris entre O et 3 inclus).Ainsi o à chaque huitième de tour dans le sens où il dévisse la bague 13 , (figure 13 , flèche 23) , l'utilisateur perçoit le passage d'un des cliquets 21 ou 30 . Regarding the ring 13 9 oz was equipped with two inner pawls 21 and 30 t offset year gulairement a impa number of round tower ((2n + 1) .45 g degrees where n is an integer between O and 3 inclusive) .Thus o each eighth of a turn in the direction where he unscrews the ring 13 (Figure 13, arrow 23), the user perceives the passage of one of the pawls 21 or 30. Par contre , toute rotation en sens inverse (figure 14 g flèche 24) demeure interdite. For against any rotation in the opposite direction (Figure 14 arrow 24 g) remains prohibited.

Le fonctionnement est le suivant s The operation is as follows s
La réglage steffectue comme précédemment , par dévissage de la bague 13 (flèche 23) s jusqu'à définir exactement la distance 25 voulue . Adjusting steffectue as above, by unscrewing the ring 13 (arrow 23) s to 25 define exactly the desired distance. Ce réglage (figures 17 2 18) s'effectue par contrôle visuel t tactile et/ou auditif , en comptant les crans dont chacun correspond à un huitième de tour .Une fois le réglage effectué, il suffit de visser la tige 4 dans la couronne filetée 6 (figure 16 , flèche 28) g pour provoquer l'injection jus qu'à ce que la bague 13 vienne ànouveau en butée sur la couronne 6 This setting (2 Figures 17 18) is effected by visual inspection t tactile and / or auditory, by counting the notches each corresponding to one-eighth turn .Once the adjustment, it is sufficient to screw the shank 4 into the crown thread 6 (Figure 16, arrow 28) to cause the injection g juice that that the ring 13 comes into abutment on the ànouveau ring 6
