Abstract

The syringe incorporates a mobile guard (1) to hold and guide the needle, along which it slides after manually releasing lugs (9, 10) engaging with holes (13, 14) in a holder (2) to determine the length of the needle to be employed for an injection or to cover it completely at the end of the plunger's injection stroke. The guard (1), the holder (2) and a needle cap (15) form a sealed assembly which isolates the tip of the needle from external contamination during storage.

Description

DESCRIPTION
La présente invention concerne un dispositif d'injection prérempli de produits pharmaceutiques permettant d'une part de régler la longueur de l'aiguille avant l'injection et d'autre part de neutraliser la dite aiguille aprés injection.DESCRIPTION
The present invention relates to an injection device pre-filled with pharmaceutical products making it possible on the one hand to adjust the length of the needle before injection and on the other hand to neutralize said needle after injection.

La différence des morphotypes humains impose d'avoir recours à des aiguilles de longueur variable selon les individus;et le risque de contamination par piqûre accidentelle avec une aiguille souillée impose de neutraliser la dite aiguille aprés injection. The difference in human morphotypes requires the use of needles of variable length depending on the individual; and the risk of contamination by accidental pricking with a dirty needle requires neutralizing said needle after injection.

Le dispositif selon l'invention permet de répondre à ce double objectif.Il comporte selon une première caractéristique une partie avant appelée garde qui coulisse avec la partie arrière appelée poignée de façon ajustable le long de l'aiguille pour en déterminer la longueur apparente avant l'injection jusqu'à une position extrême qui la masque intégralement aprés l'injection.Selon une autre caractéristique le dispositif comprend un tube de verre contenant le liquide à injecter qui est délimité par un piston amont et un piston aval.Le piston aval proche de l'ouverture du tube est destiné à être perforé par la pointe arrière de l'aiguille solidaire de la poignée puis à progresser dans le tube sur lequel s'exerce la forc de l'utilisateur pour comprimer le liquide qui s'écoule alors par l'aiguille.Il est à noter que le piston amont ne se déplace pas pendant la phase d'injection; en effet, sa contrainte de serrage dans le tube, associée à un rectrecissement du tube luiSpermettent de rester immobile. The device according to the invention makes it possible to meet this double objective. It comprises, according to a first characteristic, a front part called the guard which slides with the rear part called the handle in an adjustable manner along the needle to determine its apparent length before l injection to an extreme position which completely hides it after the injection. According to another characteristic, the device comprises a glass tube containing the liquid to be injected which is delimited by an upstream piston and a downstream piston. the opening of the tube is intended to be perforated by the rear point of the needle secured to the handle and then to advance in the tube on which the user's force is exerted to compress the liquid which then flows through the needle. Note that the upstream piston does not move during the injection phase; indeed, its tightening stress in the tube, associated with a shrinking of the tube allows it to remain stationary.

Une fois l'injection effectuée, le piston aval a rejoint le piston amont, et si l'utilisateur continue d'exercer une force sur le tube, celui-ci poursuit sa course pour faire progresser en la poussant,la gare de l'injecteur le long de l'aiguille jusqu'àla recouvrir complètement pour la neutraliser.Les pistons amont et aval ont alors rejoint le fond du tube qui est pourvu d'un évent permuttant à l'air compris entre le piston amont et le fond du tube de s'évacuer. Once the injection has been carried out, the downstream piston has joined the upstream piston, and if the user continues to exert a force on the tube, the latter continues its course to advance by pushing it, the station of the injector along the needle until completely covering it to neutralize it. The upstream and downstream pistons then joined the bottom of the tube which is provided with an air permutant vent between the upstream piston and the bottom of the evacuate.

Selon des modes particuliers de réalisation
-la garde sera pourvue d'un protecteur d'aiguille étanch5. According to particular embodiments
-the guard will be provided with a waterproof needle protector5.

-la garde et la poignée avant auront dans leur configuration de stockage une liaison étanche qui isolera l'aiguille dans un volume clos la protégeant des contaminations externes. -the guard and the front handle will have in their storage configuration a sealed connection which will isolate the needle in a closed volume protecting it from external contamination.

-le tube en verrue pourra être monté d'avance sur la poignée via son piston aval qui recouvrira la pointe arrière de l'aiguille tel un protecteur d'aiguille. -the wart tube may be mounted in advance on the handle via its downstream piston which will cover the rear point of the needle like a needle protector.

-la partie de la poignée sur laquelle sera emboité le piston aval s'appelle le plot central et il comportera deux colerettes qui maintiendront un bourrelet interne aval dans une position de stockage stable qui préviendra toute perforation accidentelle du piston ainsi que tout déboitement intempestif. -the part of the handle on which the downstream piston will be fitted is called the central stud and it will include two flanges which will maintain an internal downstream bead in a stable storage position which will prevent any accidental perforation of the piston as well as any untimely dislocation.

La figure 3 représente l'injecteur aprés l'injection et avec l'aiguille neutralisée, selon une coupe longitudinale.Figure 3 shows the injector after injection and with the needle neutralized, in a longitudinal section.

En réference à ces dessins, le dispositif comprend une partie avant dite garde (1) emboitée de façon coulissante avec une partie arrière dite poignée (2) et avec l'aiguille (3).L'aiguille (3) est solidaire de la poignée (2) à laquelle elle est reliée par le plot central (4), alors qu'elle est uniquement guidée par la garde (l).Garde (1) et poignée (2) comportent un emboitement étanche en (5) pour constituer un volume (6) isolé de l'extérieur.ta garde (1) comporte deux bras (7) et (8) munis d'ergots (9) et (10) qui s'enclenchent dans des orifices (11) (12) et (13) (14) qui correspondent respectivement à une position d'aiguille longue et à une position d'aiguille courte.  With reference to these drawings, the device comprises a front part called a guard (1) fitted in a sliding manner with a rear part called a handle (2) and with the needle (3). The needle (3) is integral with the handle (2) to which it is connected by the central stud (4), while it is only guided by the guard (l). Guard (1) and handle (2) have a watertight socket in (5) to constitute a volume (6) isolated from the outside. your guard (1) has two arms (7) and (8) provided with lugs (9) and (10) which engage in holes (11) (12) and (13) (14) which correspond respectively to a long needle position and a short needle position.

L'opérateur n'a qu'à exercer une pression sur les ergots (9) et (10) pour les dégager et translater la garde à la position correspondant à la longueur d'aiguille souhaitée. The operator only has to exert pressure on the lugs (9) and (10) to release them and translate the guard to the position corresponding to the desired needle length.

Une fois la longueur d'aiguille désirée établie , l'opérateur ôte le protecteur d'aiguille (15) et exerce une force sur le fond (16) du tube (17) qui descend le long du plot (4) entrainant avec lui le piston aval (18) jusqu'zen butée (19) à la base du plot (4) qui l'immobilise.L'extrémité (20) de l'aiguille (3) a alors perforé le piston aval (18) dont le bourrelet interne (30) initialement maintenu entre les deux colerettes (24) et (25) est passé sous la colerette (24).La progression du tube (17) entraine avec lui le piston amont (22) dont il est solidaire grâce à la force de serrage dûe à la contrainte du piston en élastomère et grâce à un retrecissement (23) du tube en verre (17) qui constitue un frein.Comprimé, le liquide s'écoule par l'aiguille.En fin d'injection, le piston amont (22) a rejoint le piston aval (18).Si l'opérateur continue néanmoins le mouvement de l'injection, le piston amont (22) en butée avec le piston aval (18) coulissera aprés avoir passé le retrecissement (23) vers le fond (16) du tube (17) alors que la partie avant (28) du tube (17) viendra coiffer les extrémités inclinées (26) et (27) dégageant ainsi lesergots (9) et (10) des orifices (11) (12) ou (13) (14).La progression du tube sur les ergots (9) et (10) poussera la garde (1) le long de l'aiguille (3) pour venir la recouvrir intégralement.Il est à noter qu'il existe à la base de la poignée (2) un décroché (29) qui permet aux extrémités (26) et (27) recentrées par la face interne du tube (17) de venir se cliquer de façon à rendre irréversible le mouvement de protection de la garde (1). L'air compris entre le fond (16) du tube (17) se sera évacué par l'évent (31). Once the desired needle length has been established, the operator removes the needle protector (15) and exerts a force on the bottom (16) of the tube (17) which descends along the stud (4) carrying with it the downstream piston (18) up to the stop (19) at the base of the stud (4) which immobilizes it. The end (20) of the needle (3) has then perforated the downstream piston (18) including the bead internal (30) initially maintained between the two flanges (24) and (25) is passed under the flange (24). The progression of the tube (17) drives with it the upstream piston (22) with which it is secured by force tightening due to the stress of the elastomeric piston and thanks to a narrowing (23) of the glass tube (17) which constitutes a brake.Compressed, the liquid flows through the needle.At the end of injection, the piston upstream (22) has joined the downstream piston (18) .If the operator nevertheless continues the movement of the injection, the upstream piston (22) in abutment with the downstream piston (18) will slide after having passed é the narrowing (23) towards the bottom (16) of the tube (17) while the front part (28) of the tube (17) will cap the inclined ends (26) and (27) thus releasing the pins (9) and ( 10) orifices (11) (12) or (13) (14) .The progression of the tube on the lugs (9) and (10) will push the guard (1) along the needle (3) to come the It should be noted that there is a hook (29) at the base of the handle (2) which allows the ends (26) and (27) centered by the internal face of the tube (17) to click so as to make the guard protection movement (1) irreversible. The air between the bottom (16) of the tube (17) will be evacuated by the vent (31).
