Abstract
Description
L'invention se rapporte à un dispositif de protection pour une aiguille tubulaire comportant une partie proximale perforante et une partie distale raccordée à une conduite. The invention relates to a protection device for a tubular needle comprising a perforating proximal part and a distal part connected to a pipe.
L'invention s'applique indifféremment aux matériels d'injection d'un liquide dans un milieu de réception, tel dans un site implanté ou, aux dispositifs de prélèvement d'un liquide dans un milieu de prélèvement. The invention applies equally to equipment for injecting a liquid into a receiving medium, such as an implanted site or to devices for withdrawing a liquid from a collecting medium.
Par le terme "site", on désignera ci-aprés tout milieu dans lequel l'aiguille peut être engagée. The term "site" will denote below any medium in which the needle can be engaged.
Le dispositif de l'invention est destiné à la prévention des piqûres accidentelles de personnes qui manipulent ces matériels. The device of the invention is intended for the prevention of accidental bites by people who handle these materials.
Ces accidents interviennent essentiellement lors du retrait d'une aiguille d'un milieu d'injection ou de prélèvement. These accidents mainly occur during the withdrawal of a needle from an injection or sampling medium.
Dans ce domaine, pour réduire la probabilité de piqûres par de telles aiguilles, on connaît, par exemple, un dispositif
EP-A 0.521.145 qui, intitulé "protection pour canule", comprend
- une aiguille tubulaire classiquement équipée d'une partie proximale perforante et d'une partie distale axialement prolongée par une pièce tubulaire de préhension qui, de diametre supérieur à celui de l'aiguille, est raccordée à une conduite de circulation de fluide,
- une coiffe tubulaire enveloppant la partie distale de l'aiguille et sa pièce de préhension et, dans laquelle coiffe ces éléments peuvent, pendant que s'effectue le retrait de l'aiguille d'un site, par traction au niveau de la conduite de circulation, être translatés jusqu'à ce que l'aiguille se trouve entierement dans la coiffe tubulaire.In this field, to reduce the probability of being bitten by such needles, a device is known, for example
EP-A 0.521.145 which, entitled "cannula protection", includes
a tubular needle conventionally equipped with a perforating proximal part and a distal part axially extended by a tubular gripping part which, of diameter greater than that of the needle, is connected to a fluid circulation pipe,
- a tubular cap enveloping the distal part of the needle and its gripping part and, in which cap these elements can, while the needle is withdrawn from a site, by traction at the level of the circulation, be translated until the needle is completely in the tubular cap.
Ce dispositif a ses avantages, mais
- d'une part, il est d'un encombrement longitudinal tel que son utilisation prolongée ne peut être envisagée lorsque l'aiguille doit être implantée perpendiculairement à la surface externe d'un site d'utilisation et,
- d'autre part et surtout, la protection de cette aiguille n'est pas automatique, ou au moins quasi-automatique, lors du retrait de ce site.This device has its advantages, but
on the one hand, it is of a longitudinal size such that its prolonged use cannot be envisaged when the needle must be implanted perpendicular to the external surface of a site of use and,
- on the other hand and above all, the protection of this needle is not automatic, or at least quasi-automatic, when withdrawing from this site.
Un résultat que l'invention vise à obtenir est un dispositif qui remédie à ces deux inconvénients. One result which the invention aims to obtain is a device which overcomes these two drawbacks.
A cet effet, l'invention a pour objet un dispositif du type précité, notamment caractérisé en ce que
- d'une part, le moyen d'articulation bistable du dispositif de protection comprend
au moins indirectement solidaire de la pièce de base, un organe qui assure la fonction d'articulation de la coiffe entre ses deux positions, et ce, de manière telle qu'en position dite première, la coiffe se trouve substantiellement en retrait par rapport à un plan au delà duquel l'aiguille s'étend et, dans lequel plan, la butée, destinée à entrer en contact avec une surface du site, se trouve comprise, et
un moyen, de verrouillage de la coiffe dans sa position dite première, c'est à dire dans la position dans laquelle elle dégage totalement l'aiguille, ce moyen mettant en oeuvre au moins une pièce mobile entre deux emplacements dont un emplacement dans lequel elle immobilise la coiffe dans sa position première et, un emplacement dans lequel elle libère ladite coiffe, rendant possible son déplacement vers la seconde position dans laquelle elle enveloppe l'aiguille,
- d'autre part, la coiffe présente une surface qui, en sa position dite première, se trouve comprise dans le plan qui contient la butée, destinée à entrer en contact avec une surface du site.To this end, the invention relates to a device of the aforementioned type, in particular characterized in that
- On the one hand, the bistable articulation means of the protection device comprises
at least indirectly secured to the base part, a member which ensures the articulation function of the cap between its two positions, and this, so that in the so-called first position, the cap is substantially set back with respect to a plane beyond which the needle extends and, in which plane, the stop, intended to come into contact with a surface of the site, is included, and
a means for locking the cap in its so-called first position, that is to say in the position in which it completely releases the needle, this means employing at least one movable part between two locations including a location in which it immobilizes the cap in its first position and, a location in which it releases said cap, making it possible to move it to the second position in which it envelops the needle,
- On the other hand, the cover has a surface which, in its so-called first position, is included in the plane which contains the stop, intended to come into contact with a surface of the site.
L'invention sera bien comprise à la lecture de la description ci-après faite à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente schématiquement
- figures 1 et 2 : des vues latérales de deux formes de réalisation de dispositif selon l'invention,
- figures 3 et 4 : des vues d'une extrémité des dispositifs des figures 1 et 2 en situation d'utilisation.The invention will be clearly understood on reading the description below made by way of nonlimiting example, with reference to the attached drawing which schematically represents
FIGS. 1 and 2: side views of two embodiments of the device according to the invention,
- Figures 3 and 4: views of one end of the devices of Figures 1 and 2 in use.
En se reportant au dessin, on voit un dispositif 1 de protection pour une aiguille tubulaire 2 comportant une partie proximale 2A perforante et une partie distale 2B au moins indirectement raccordée à une conduite 3 de circulation d'un liquide (non représenté). Referring to the drawing, we can see a protective device 1 for a tubular needle 2 comprising a perforating proximal part 2A and a distal part 2B at least indirectly connected to a pipe 3 for circulating a liquid (not shown).
Le dispositif 1 comprend une coiffe 4 qui, articulée au niveau de l'extrémité distale 2B de l'aiguille 2 par un moyen 5 à cet effet, est mobile entre deux positions extrêmes P1 et P2 dont une première position P1 dans laquelle elle dégage totalement l'aiguille 2 et, une seconde position P2 dans laquelle elle recouvre cette aiguille 2, de manière à entraver tout contact avec cette dernière. The device 1 comprises a cap 4 which, articulated at the distal end 2B of the needle 2 by means 5 for this purpose, is movable between two extreme positions P1 and P2 including a first position P1 in which it completely releases the needle 2 and, a second position P2 in which it covers this needle 2, so as to hinder any contact with the latter.
En sa position seconde P2, la coiffe a été représentée en pointillés. In its second position P2, the cap has been shown in dotted lines.
Par l'expression "dégage totalement l'aiguille", on comprendra une position dans laquelle l'aiguille peut être plantée dans un site 6 en vue d'assurer sa fonction de circulation d'un fluide. By the expression "completely releases the needle", it will be understood a position in which the needle can be planted in a site 6 in order to ensure its function of circulation of a fluid.
Par site 6, on désigne tout matériau 6 dans lequel une aiguille tubulaire 2 peut être plantée. By site 6 is meant any material 6 in which a tubular needle 2 can be planted.
Une fraction du site 6 a été représentée en traits mixtes forts. A fraction of site 6 has been shown in strong phantom.
Le moyen 5 d'articulation que comprend le dispositif 1 est du type bistable, c'est à dire, qu'il assure le maintien effectif de la coiffe dans chacune des deux positions extrêmes P1 et P2. The articulation means 5 that the device 1 comprises is of the bistable type, that is to say, that it ensures the effective retention of the cap in each of the two extreme positions P1 and P2.
L'aiguille 2 est, à son extrémité distale 2B, solidaire d'une pièce 7 de base qui présente
- une butée 7A disposée pour, lors de l'engagement de ladite aiguille dans un site 6, entrer en contact avec une surface 6A délimitant le dit site 6 et limiter l'engagement de la dite aiguille dans ce dernier, et
- une surface 7B qui, distincte de la butée 7A constitue au moins indirectement une portée de préhension, c'est à dire une portée qui, permet la manipulation de l'aiguille 2.The needle 2 is, at its distal end 2B, secured to a base part 7 which has
a stop 7A arranged for, during the engagement of said needle in a site 6, coming into contact with a surface 6A delimiting said site 6 and limiting the engagement of said needle in the latter, and
a surface 7B which, distinct from the stop 7A constitutes at least indirectly a gripping surface, that is to say a surface which allows the manipulation of the needle 2.
Par manipulation, on désigne notamment les opérations d'implantation et de retrait de l'aiguille. By manipulation, one indicates in particular the operations of implantation and withdrawal of the needle.
Le dispositif de l'invention est remarquable en ce que
- d'une part, le moyen 5 d'articulation bistable du dispositif 1 de protection comprend
au moins indirectement solidaire de la pièce de base 7, un organe 5A qui assure la fonction d'articulation de la coiffe entre ses deux positions P1, P2, et ce, de manière telle qu'en position dite première P1, la coiffe 4 se trouve substantiellement en retrait par rapport à un plan 8 au delà duquel l'aiguille 2 s'étend et, dans lequel plan, la butée 7A, destinée à entrer en contact avec une surface 6A du site 6, se trouve comprise, et
un moyen 5B, de verrouillage de la coiffe 4 dans sa position P1 dite première, c'est à dire dans la position dans laquelle elle dégage totalement l'aiguille 2, ce moyen 5B mettant en oeuvre au moins une pièce 9 mobile entre deux emplacements El, E2 dont un emplacement El dans lequel elle immobilise la coiffe 4 dans sa position première P1 et, un emplacement E2 dans lequel elle libère ladite coiffe 4, rendant possible son déplacement vers la seconde position P2 dans laquelle elle enveloppe l'aiguille 2,
- d'autre part, la coiffe 4 présente une surface 4A qui, en sa position P1 dite première, se trouve comprise dans le plan 8 qui contient la butée 7A, destinée à entrer en contact avec une surface 6A du site 6.The device of the invention is remarkable in that
- On the one hand, the bistable articulation means 5 of the protection device 1 comprises
at least indirectly secured to the base part 7, a member 5A which ensures the function of articulation of the cap between its two positions P1, P2, and this, so that in the so-called first position P1, the cap 4 is is substantially set back from a plane 8 beyond which the needle 2 extends and, in which plane, the stop 7A, intended to come into contact with a surface 6A of the site 6, is included, and
a means 5B, for locking the cover 4 in its so-called first position P1, that is to say in the position in which it completely releases the needle 2, this means 5B using at least one piece 9 movable between two locations El, E2 including a location El in which it immobilizes the cover 4 in its first position P1 and, a location E2 in which it releases said cover 4, making it possible to move it to the second position P2 in which it envelops the needle 2,
- on the other hand, the cover 4 has a surface 4A which, in its so-called first position P1, is included in the plane 8 which contains the stop 7A, intended to come into contact with a surface 6A of the site 6.
Pour assurer sa fonction, la pièce mobile 9 comprend au moins une butée 9A, 9B destinée à coopérer avec au moins une butée llA, llB quant à elle portée par l'un des éléments que sont la coiffe 4 et la pièce de base 7. To ensure its function, the moving part 9 comprises at least one stop 9A, 9B intended to cooperate with at least one stop 11A, llB in turn carried by one of the elements that are the cover 4 and the base part 7.
Le respect de ces caractéristiques techniques essentielles permet d'obtenir le résultat visé par l'invention, à savoir, un dispositif de protection d'aiguille qui, tout en présentant un encombrement tel que l'utilisation prolongée peut être envisagée avec l'aiguille implantée perpendiculairement à la surface externe d'un site, permet la protection quasiautomatique de l'aiguille. Compliance with these essential technical characteristics makes it possible to obtain the result targeted by the invention, namely, a needle protection device which, while having a space requirement such that prolonged use can be envisaged with the needle implanted perpendicular to the external surface of a site, allows almost automatic protection of the needle.
Tel que cela est symbolisé sur le dessin (figure 1), l'organe 5A, qui assure la fonction d'articulation, peut consister en une charnière classique mais cela n'est pas limitatif et cet organe 5A peut, avantageusement, être simplement constitué par un élément flexible (non représenté). As symbolized in the drawing (FIG. 1), the member 5A, which performs the articulation function, can consist of a conventional hinge but this is not limiting and this member 5A can, advantageously, be simply constituted by a flexible element (not shown).
De préférence et de manière remarquable, le dispositif 1 comprend un moyen 10 de déplacement automatique de la coiffe 4 de sa position P1 dite première vers sa position P2 dite seconde, lors du déplacement de l'organe de verrouillage 5B en emplacement E2 dans lequel il libère la dite coiffe 4. Preferably and remarkably, the device 1 comprises a means 10 for automatic displacement of the cover 4 from its position P1 said first to its position P2 said second, during the displacement of the locking member 5B in location E2 in which it releases said cap 4.
Par cela la protection de l'aiguille 2 est automatique. By this the protection of the needle 2 is automatic.
Le moyen 10 de déplacement automatique est par exemple essentiellement constitué par un organe élastique. The means 10 for automatic displacement is for example essentially constituted by an elastic member.
L'homme de l'art est à même de concevoir ce moyen 10 de déplacement. Those skilled in the art are able to design this means of movement.
Avantageusement, ce moyen 10 de déplacement peut être combiné au moyen 5 d'articulation bistable et, par exemple, consister en un élément flexible assurant une fonction de ressort. Advantageously, this displacement means 10 can be combined with the bistable articulation means 5 and, for example, consist of a flexible element ensuring a spring function.
En ce qui concerne le moyen 5B de verrouillage, dans une forme de réalisation, il comprend
- une pièce 9 qui, destinée à assurer une fonction de pêne, est, par un moyen lIA à cet effet, guidée en translation sur la pièce de base 7 et ce, entre deux emplacements El, E2 dont, d'une part, un emplacement El dans lequel en coopérant avec une butée llB portée par la coiffe 4, elle immobilise ladite coiffe 4 dans sa position première P1 et, d'autre part, un emplacement E2 dans lequel elle libère la butée llB solidaire de la coiffe 4, rendant possible son déplacement vers la seconde position P2 dans laquelle elle enveloppe l'aiguille 2,
- solidaire de la pièce 9 de verrouillage, une surface 7B qui permet l'actionnement de cette pièce 9 pour son déplacement d'un (El) de ses emplacements (El, E2) à l'autre (E2).As regards the locking means 5B, in one embodiment, it comprises
- A part 9 which, intended to provide a bolt function, is, by means LIA for this purpose, guided in translation on the base part 7 and this, between two locations El, E2 including, on the one hand, a location El in which by cooperating with a stopper 11B carried by the cover 4, it immobilizes said cover 4 in its first position P1 and, on the other hand, a location E2 in which it releases the stopper 11B secured to the cover 4, making possible its displacement towards the second position P2 in which it envelops the needle 2,
- integral with the locking part 9, a surface 7B which allows the actuation of this part 9 for its displacement from one (El) of its locations (El, E2) to the other (E2).
Le moyen llA de guidage en translation consiste, par exemple, en un alésage réalisé dans la pièce 7 de base. The means 11A for guiding in translation consists, for example, of a bore produced in the base part 7.
Le moyen llA de guidage constitue donc bien l'une llA des butées llA, llB portées par l'un des éléments que sont la coiffe 4 et la pièce de base 7. The guide means llA therefore constitutes one of the stops llA, llB carried by one of the elements that are the cover 4 and the base part 7.
De manière remarquable, la pièce 9 de verrouillage, comprend une première partie 9C essentiellement longiligne qui, montée coulissante sur la pièce de base 7 entre les deux emplacements El, E2 définis, assure la fonction de pêne et, une seconde partie 9D consistant en une anse de manoeuvre qui s'étend approximativement à ladite première partie 9C et, porte la surface 7B permettant son actionnement en translation entre ses deux emplacements El, E2. Remarkably, the locking part 9 comprises a first, essentially elongated part 9C which, slidingly mounted on the base part 7 between the two defined locations E1, E2, provides the bolt function and, a second part 9D consisting of a operating handle which extends approximately to said first part 9C and carries the surface 7B allowing it to be actuated in translation between its two locations El, E2.
De manière également remarquable, la première partie 9C de la pièce 9 de verrouillage est, sur la pièce 7 de base, guidée en rotation autour de son axe de translation, et ce, entre deux situation S1, S2 dont une première situation S1 dans laquelle l'anse 9D qu'elle porte fait saillie sur la pièce de base 7 sur une face opposée à celle présentant l'aiguille 2 et, une seconde situation S2, dans laquelle l'anse 9D se trouve sensiblement rabattue contre la pièce de base 7. Also remarkably, the first part 9C of the locking part 9 is, on the basic part 7, guided in rotation about its axis of translation, and this, between two situations S1, S2 including a first situation S1 in which the handle 9D which it carries projects on the base part 7 on a face opposite to that presenting the needle 2 and, a second situation S2, in which the handle 9D is substantially folded back against the base part 7 .
Par cela, le dispositif 1 peut former une saillie de hauteur réduite au dessus de la surface du site sur laquelle il est en appui. By this, the device 1 can form a projection of reduced height above the surface of the site on which it is supported.
Avantageusement l'anse constitue le moyen de préhension de la pièce de base 7. Advantageously, the handle constitutes the means for gripping the base part 7.
Pour ce qui est de la coiffe 4, l'homme de l'art est à même de la concevoir, sachant que c'est latéralement qu'elle doit venir envelopper l'aiguille. As for the cap 4, the skilled person is able to design it, knowing that it is laterally that it must come to wrap the needle.
Dans une variante de réalisation (figures 2 et 4), le moyen 5B de verrouillage comprend
- d'une part, au moins deux portées llA, llB qui, chacune solidaire de la pièce de base 7 et de la coiffe 4, sont accessibles lorsque les dites coiffe 4 et pièce 7 de base sont en appui sur la surface externe 6A d'un site 6 et,
- d'autre part, au moins une pièce 9 mobile qui, séparable de la coiffe 4 et de la pièce de base 7, comprend des butées 9A, 9B destinées à coopérer de manière amovible avec leurs portées llA, llB afin de maintenir fermement la coiffe en sa position dite première P1.In an alternative embodiment (Figures 2 and 4), the locking means 5B comprises
- On the one hand, at least two ranges llA, llB which, each integral with the base part 7 and the cap 4, are accessible when said cap 4 and part 7 base are supported on the external surface 6A d 'a site 6 and,
- on the other hand, at least one movable part 9 which, separable from the cover 4 and the base part 7, includes stops 9A, 9B intended to cooperate in a removable manner with their ranges llA, llB in order to firmly maintain the cap in its so-called first position P1.
Selon une forme préférée de réalisation de cette variante, les portées llA, llB sont
- d'une part, formées sur la pièce de base 7 et sur la coiffe de manière à être chacune accessibles sur une face opposée à celle destinée à être placée en appui sur le site 6 et,
- d'autre part, sensiblement alignées de manière à pouvoir être saisies sensiblement simultanément par la pièce mobile 9.According to a preferred embodiment of this variant, the ranges llA, llB are
on the one hand, formed on the base part 7 and on the cover so as to be each accessible on a face opposite to that intended to be placed in abutment on the site 6 and,
- on the other hand, substantially aligned so that they can be gripped substantially simultaneously by the moving part 9.
Les portées de préhension llA, llB sont, par exemple, réalisées en saillie ou en creux. The gripping surfaces llA, llB are, for example, made projecting or recessed.
De préférence, la pièce 9 mobile destinée à coopérer avec les portées de préhension llA, llB consite en une machoire 9 d'une pince 12. Preferably, the movable part 9 intended to cooperate with the gripping surfaces llA, llB consists of a jaw 9 of pliers 12.
