The present invention relates to a syringe of a new type, of the kind used for injecting various products, in particular medical ~ chemicals, adhesives t dental paste, resins 2 or the like.
L'invention vise plus particulièrement à munir la seringue d'un système de dosages , qui permettent de doser avec précision la quantité à injecter.Bien mieux , la seringue selon l'invention vise à permettre à l'utilisateur d'effectuer , à partir d'un unique remplissage du corps de la seringue , plusieurs injections successives , dont chacune est disée avec précision . Un tel résultat est particulièrement intéressant pour certains utilisateurs malades (cardiaques Du diAbétiquès) , qui pratiquent sur eux-m#mes des injcetions fréquentes et répétées Il peut s'agir d'une seringue préremplie en milieu industriel t ou d'une seringue que l'utilisateur remplit lui-même. The invention more particularly aims to provide the syringe with a dosing system, which makes it possible to precisely dose the quantity to be injected. Better still, the syringe according to the invention aims to allow the user to carry out, from a single filling of the syringe body, several successive injections, each of which is said with precision. Such a result is particularly interesting for certain sick users (cardiac of the Diabetics), who practice frequent and repeated injections on themselves. It can be a pre-filled syringe in an industrial environment or a syringe that the user fills himself.
Enfin , l'invention vise à réaliser un tel système de dosage t Oui présente des repères décelables au toucher et à l'dure , si bien que le système peut être utilisé aussi bien par un aveugle que par un voyant ou un sourd. Finally, the invention aims to produce such a dosing system t Yes has marks detectable by touch and by hardness, so that the system can be used both by a blind person and by a sighted or deaf person.
D'une manière générale ,une seringue selon l'invention peut être utilisée pour injecter et doser les produits les plus divers , notamment des produits oxydables à l'air . Cela peut concerner par exemple
- une colle cyanolite
- une pâte dentaire utilisée pur un prothésiste , ou pour
la prise d'empreintes ( pâtes à silicones)
- un médicament , tel que l'insuline , l'héparine , etc...In general, a syringe according to the invention can be used to inject and dose the most diverse products, in particular products which can be oxidized in air. This can concern for example
- cyanolite glue
- a dental paste used for a prosthetist, or for
taking impressions (silicone pastes)
- a drug, such as insulin, heparin, etc ...
Enfin , la partie avant de la seringue peut titre équipée d'une aiguille creuse de tous types connus par exemple pour les piqûres hypodermiques
Le dessin annexé t donné à titre d'exempie non limitatif , permettra de mieux comprendre les caractéristiques de l'invention , et les avantages qu'elle est susceptible de procurer.Finally, the front part of the syringe can title equipped with a hollow needle of all types known for example for hypodermic punctures

the piston.
On a représenté sur les dessins une serin
gue 1 selon l'invention , dans le corps tubulaire 2 de la
quelle coulisse un piston 3 t solidaire d'une tige 4 que
termine la teste 5 d'un poussoir.We have shown in the drawings a canary
gue 1 according to the invention, in the tubular body 2 of the
which slides a piston 3 t secured to a rod 4 that
ends test 5 of a pushbutton.
A son sommet , le coyps tubulaire 2 est
solidaire d'une couronne de guidage 6 qui peut éventuelle
ment comporter e à la manière connue , deux ailettes 7?.At its apex, the tubular coyps 2 is
integral with a guide ring 6 which may optionally
ment e include in the known manner, two fins 7 ?.
A l'extrémité opposée , le corps 2 est
solidaire dtune embase 8 t dans laquelle on peut adapter
à la manière connue , l'embout 9 d'une aiguille creuse 10,
Selon l'invention , la tige 4 est pourvue
d'un filetage extérieur 11, alors qu'elle est creusée de
rainures longitudinales 12 . Ces rainures sont t par exem
ple , au nombre de quatre . Sur ce filetage est vissée une bague 13 formant écrou , pourvue d'au moins un cliquet élastique intérieur 14 (figures 8 à 10) . De plus ,elle comporte un repère extérieur 15 t disposé en relief
La couronne 6 des figures 1 à 10 b a 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
Enfin , un repère extérieur 18 est prévu en relief sur la couronne 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.At the opposite end, the body 2 is
attached to an 8 t base in which we can adapt
in the known manner, the tip 9 of a hollow needle 10,
According to the invention, the rod 4 is provided
an external thread 11, while it is hollowed out
longitudinal grooves 12. These grooves are t for example
ple, four in number. On this thread is screwed a ring 13 forming a nut, provided with at least one internal elastic pawl 14 (FIGS. 8 to 10). In addition, it includes an external mark 15 t arranged in relief
The crown 6 of FIGS. 1 to 10 has an internal smooth wall 16 (FIG. 1), in which the threaded rod 4 can slide freely. In addition, an internal finger 17 protrudes over the interior of the wall 16, in one longitudinal grooves 12 t which prevents the rod 4 of the piston 3 from turning in the crown 6
Finally, an external reference 18 is provided in relief on the crown 6. This relief 18 may other produced with the finger 17 t in the form of a single removable piece 17-18 (FIGS. 6 and 7) t or else be simply ground in relief, in one piece with the crown 6.
Le fonctionnement est le suivant
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.The operation is as follows
It can be seen, in FIGS. 2 to 4, that the presentation of the needle 10 (FIG. 2) t the perforation of the sterile membrane 19 (FIG. 3), by screwing the end piece 9 t and extracting the sterile packaging case 20 (FIG. 4), are carried out without at any time t the needle 10 being liable 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 . Ce dévissqge est repéré exactement:
- d'une part , visuellement t par simple observation du
décalage des repères 15 ( sur la bague 13) et 18 ( sur
la couronne 6)
- d'autre part , de façon tactile et auditive t par per
ception de chaque passage sur une rainure 12 , d'un
cliquet élastique 21 dont est pourvue la paroi interne
de la bague 13.Then 2 it suffices for the user to unscrew the ring 13 (FIG. 5), by a marked quantity which corresponds exactly to the dose of product which the piston 3 must inject. This unscrewing is identified exactly:
- on the one hand, visually t by simple observation of the
offset marks 15 (on ring 13) and 18 (on
crown 6)
- on the other hand, tactile and auditory t by per
ception of each passage on a groove 12, of a
elastic pawl 21 with which the internal wall is provided
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. The precision of the tactile or visual identification t can be further improved by regularly distributing eight notches 22 on the periphery 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 can be seen that the pawl 21 makes it possible to freely unscrew the ring 13 on the threaded rod 4 (rotation in the direction of the arrow 23), while it is not possible to screw it (arrow 24, FIG. 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 . 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. The ring 13 thus being immobilized on the rod 4, at a distance 25 exactly calibrated (Figure 11), it suffices to dtcnf9ncer the pusher 5, with a pressure of the thumb 26 (Figure 12) t to inject very exac toment the desired dose of the product contained in the tubular body 2. The injection continues until the ring 13 again abuts against the crown 6. The syringe is then ready for another injection & practice later by a new adjustment of the ring 13 t mulon unscrews as shown in s Figures 8 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 . 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 . Au contraire A il interdit tout recul du piston 3 ( dévissage dans le sens de la flèche 29 ( figure 15). In the variant of FIGS. 13 to 19, the interior of the crown 6 is also t, threaded and provided with at least one pawl 27 t which cooperates with the grooves 12. This pawl 27 is oriented so as to allow free screwing of the rod 4 in the direction of the arrow 28 (FIG. 16) t which causes the piston 3 to sink into the body 2. On the contrary A it prohibits any retreat of the piston 3 (unscrewing in the direction of the arrow 29 (FIG. 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 . Par contre , toute rotation en sens inverse (figure 14 g flèche 24) demeure interdite. As regards the ring 13 9, it has been fitted with two internal pawls 21 and 30 t offset angularly by an impa number of eighths of a turn ((2n + 1) .45 degrees g where n is an integer included between O and 3 included). Thus o at each eighth of a turn in the direction in which he unscrews the ring 13, (Figure 13, arrow 23), the user perceives the passage of one of the pawls 21 or 30. On the other hand, any rotation in the opposite direction (figure 14 g arrow 24) remains prohibited.
Le fonctionnement est le suivant s
La réglage steffectue comme précédemment , par dévissage de la bague 13 (flèche 23) s jusqu'à définir exactement la distance 25 voulue . 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
Le vissage de la tige 4 peut titre effectué: :
- soit en agissant sur la t8te moletée 31 de la tige 4
(figure 19) s
- soit en faisant tourner la bague 13 dans le sens de la
flèche 24 où elle entraine avec elle la tige 4
L'invention comporte , en particulier ,les avantages s uivants s
- réglage facile de chaque d ose à injecter (distance 25)
m8me pour un aveugle ou un sourd
- impossibilité d'effectuer des fausses manoeuvres
- & la fin d'une injection , la seringue est automatique~
ment prête pour l'injection suivante The operation is as follows:
The adjustment takes place as before, by unscrewing the ring 13 (arrow 23) s until exactly defining the desired distance 25. This adjustment (Figures 17 2 18) is carried out by visual and tactile or auditory control, counting the notches, each of which corresponds to an eighth of a turn. Once the adjustment has been made, simply screw the rod 4 into the crown threaded 6 (Figure 16, arrow 28) g to cause injection until the ring 13 comes again to abut on the crown 6
The screwing of the rod 4 can be carried out:
- either by acting on the knurled head 31 of the rod 4
(figure 19) s
- either by rotating the ring 13 in the direction of the
arrow 24 where it carries with it the rod 4
The invention comprises, in particular, the following advantages:
- easy adjustment of each dose to be injected (distance 25)
Even for the blind or the deaf
- impossibility of carrying out false maneuvers
- & at the end of an injection, the syringe is automatic ~
ready for the next injection
