Description

DISPOSITIF DE PROTECTION CONTRE LES PIQURES ACCIDENTELLES PAR DES AIGUILLES D'INJECTION PROTECTION DEVICE AGAINST ACCIDENTIAL STITCHES BY INJECTION NEEDLES
L'invention concerne un dispositif de protec¬ tion contre les piqûres accidentelles par des aiguilles d'injection.The invention relates to a device for protection against accidental punctures by injection needles.
On a déjà développé de nombreux moyens desti¬ nés à protéger les personnes, telles que les infirmières, qui font des injections de produits pharmaceutiques ou médicamenteux à des patients au moyen de seringues munies d'aiguilles, et qui risquent de se piquer elles-mêmes en manipulant la seringue ou l'aiguille après l'injection faite au patient.Numerous means have already been developed for protecting people, such as nurses, who inject pharmaceutical or medicinal products into patients by means of syringes fitted with needles, and who are liable to prick themselves. by handling the syringe or needle after the injection has been given to the patient.
En général, après une injection, l'aiguille doit être retirée de la seringue et jetée pour être dé- truite. Le moyen de protection le plus efficace consiste à recouvrir l'aiguille d'un étui ou capuchon rigide alors qu'elle est encore montée sur la seringue, puis à retirer l'aiguille de la seringue en la laissant à l'intérieur du capuchon, et à jeter ensemble le capuchon et l'aiguille. Comme les aiguilles sont commercialisées dans des condi¬ tionnement individuels constitués par des capuchons ri¬ gides fermés par un petit bouchon amovible ou moyen ana¬ logue ainsi que par des emballages stériles inviolables du type "blister", on peut réutiliser le capuchon de conditionnement pour recouvrir l'aiguille après usage et avant de la retirer de la seringue. Ce moyen de protec¬ tion est de toute évidence le plus économique, mais n'est pas très efficace, car les conditionnements de commercia¬ lisation des aiguilles n'ont pas été conçus pour assurer une protection contre la contamination par des aiguilles souillées.In general, after an injection, the needle must be withdrawn from the syringe and discarded to be destroyed. The most effective means of protection consists in covering the needle with a rigid case or cap while it is still mounted on the syringe, then withdrawing the needle from the syringe, leaving it inside the cap, and throw the cap and needle together. As the needles are sold in individual packaging consisting of rigid caps closed by a small removable or medium-sized plug as well as by sterile tamper-evident blister type packaging, the packaging cap can be reused for cover the needle after use and before removing it from the syringe. This means of protection is obviously the most economical, but is not very effective, since the packaging for the marketing of needles has not been designed to provide protection against contamination by contaminated needles.
L'invention a notamment pour but d'apporter une solution simple, efficace et peu coûteuse à_ ce pro¬ blème. Elle propose, à cet effet, un dispositif de protection contre les piqûres accidentelles par des ai¬ guilles d'injection, comprenant un capuchon de forme cy- lindrique ou conique destiné à contenir l'aiguille et ayant une extrémité ouverte d'introduction de l'aiguille, caractérisé en ce que le capuchon comporte des moyens de prise et de maintien d'un capuchon semblable orienté sen- siblement perpendiculairement au premier capuchon cité.The object of the invention is in particular to provide a simple, effective and inexpensive solution to this problem. To this end, it proposes a device for protection against accidental punctures by injection needles, comprising a cy-shaped cap. cylindrical or conical intended to contain the needle and having an open end for introducing the needle, characterized in that the cap comprises means for gripping and holding a similar cap oriented substantially perpendicularly to the first cited cap .
Ces moyens de prise et de maintien peuvent être constitués par un organe de serrage à déformation élastique, comprenant par exemple deux pattes formant pince, formé à l'extrémité fermée du capuchon. On peut ainsi utiliser un capuchon pour tenir à distance un autre capuchon, orienté perpendiculairement au premier et dans lequel on introduira l'aiguille.These gripping and holding means can be constituted by a clamping member with elastic deformation, comprising for example two tabs forming a clamp, formed at the closed end of the cap. It is thus possible to use a cap to hold at a distance another cap, oriented perpendicular to the first and into which the needle will be introduced.
Le dispositif selon l'invention offre donc une protection efficace contre les piqûres accidentelles par des aiguilles souillées, tout en ayant un prix de revient sensiblement égal à celui des capuchons classiques de conditionnement d'aiguilles.The device according to the invention therefore offers effective protection against accidental needlestick injuries by dirty needles, while having a cost price substantially equal to that of conventional needle packaging caps.
Selon une autre caractéristique de 1'invention, le capuchon a une section transversale à contour extérieur polygonal, et l'organe de serrage pré¬ cité délimite un logement à contour intérieur polygonal de forme et de dimensions correspondant à celles du capu¬ chon.According to another characteristic of the invention, the cap has a cross section with a polygonal outer contour, and the aforesaid clamping member defines a housing with a polygonal inner contour of shape and dimensions corresponding to those of the capu¬ chon.
Ainsi, on assure l'immobilisation en rotation du capuchon qui . est monté dans l'organe de serrage pré¬ cité.Thus, it ensures the immobilization in rotation of the cap which. is mounted in the above-mentioned clamping member.
Selon encore une autre caractéristique de l'invention, un manchon tubulaire est monté coulissant sur le capuchon de façon à pouvoir recouvrir 1'extrémité ouverte du capuchon et s'étendre au-delà de celle-ci.According to yet another characteristic of the invention, a tubular sleeve is slidably mounted on the cap so as to be able to cover the open end of the cap and extend beyond it.
Ce moyen offre une protection supplémentaire, lorsque l'aiguille est du type à deux extrémités poin¬ tues, dont l'une est utilisée pour l'injection d'une pro¬ duit à un patient et dont l'autre est utilisée pour per- forer un opercule de fermeture d'un tube contenant le produit à injecter. Dans ce cas, le manchon tubulaire précité peut recouvrir totalement l'aiguille logée dans le capuchon, en évitant les risques de piqûres acciden¬ telles.This means offers additional protection, when the needle is of the type with two pointed ends, one of which is used for injecting a product into a patient and the other of which is used for drill a seal to close a tube containing the product to be injected. In this case, the tubular sleeve above can completely cover the needle housed in the cap, avoiding the risk of accidental needle sticks.
Selon une variante de réalisation de l'invention, les moyens de prise et de maintien compren¬ nent au moins une patte elastiquement deformable formée le long du capuchon.According to an alternative embodiment of the invention, the gripping and holding means comprise at least one elastically deformable tab formed along the cap.
Cette patte peut être utilisée pour retenir un autre capuchon de même type, lorsqu'elle est engagée, sous la patte de cet autre capuchon.This tab can be used to retain another cap of the same type, when it is engaged, under the tab of this other cap.
Dans une variante de réalisation de l'invention, applicable notamment au cas des aiguilles d'injection d'insuline, l'organe de serrage est destiné à la prise et au maintien d'un fourreau de faible diamètre emboîtable sur l'aiguille.In an alternative embodiment of the invention, applicable in particular to the case of insulin injection needles, the clamping member is intended for gripping and holding a sheath of small diameter which can be fitted onto the needle.
L'invention sera mieux comprise et d'autres caractéristiques, détails et avantages de celle-ci appa¬ raîtront plus clairement à la lecture de la description qui suit, faite en référence aux dessins annexés dans lesquels : la figure 1 représente schématiquement un dis¬ positif de protection selon l'invention; la figure 2 illustre schématiquement l'utilisation de ce dispositif; les figures 3, 4 et 5 représentent des va¬ riantes de réalisation de ce dispositif.The invention will be better understood and other characteristics, details and advantages thereof will appear more clearly on reading the description which follows, made with reference to the appended drawings in which: FIG. 1 schematically represents a dis¬ protective positive according to the invention; Figure 2 schematically illustrates the use of this device; Figures 3, 4 and 5 show varia- tive embodiments of this device.
On fera tout d'abord référence aux figures 1 et 2, représentant une première forme de réalisation du dispositif selon l'invention. Ce dispositif comprend essentiellement un ca¬ puchon 10 de forme générale cylindrique ou tronconique très semblable aux capuchons classiques utilisés pour le conditionnement des aiguilles dans la technique anté¬ rieure. Ce capuchon 10 comporte une extrémité ouverteReference will firstly be made to FIGS. 1 and 2, representing a first embodiment of the device according to the invention. This device essentially comprises a cap 10 of generally cylindrical or frustoconical shape very similar to the conventional caps used for packaging needles in the prior art. This cap 10 has an open end
12 d'introduction d'une aiguille et une extrémité opposée fermée 13. L'extrémité ouverte 12 du capuchon est en gé¬ néral délimitée par un collet cylindrique 14 recevant un bouchon amovible ou un autre moyen analogue de fermeture. A son extrémité fermée, le capuchon 10 est prolongé longitudinalement par un organe 16 de prise et' de maintien du capuchon 10 d'un autre dispositif selon l'invention ou d'un capuchon classique de conditionnement d'aiguille utilisé dans la technique antérieure.12 introduction of a needle and an opposite end closed 13. The open end 12 of the cap is generally defined by a cylindrical collar 14 receiving a removable stopper or other similar closure means. At its closed end, the cap 10 is longitudinally extended by a member 16 and socket 'for holding the cap 10 of another device according to the invention or of a conventional cap packaging needle used in the prior art.
L'organe de prise et de maintien 16 est constitué de deux pattes 18 elastiquement déformables, formant pinces ou mâchoires de serrage. Ces deux pattes 18 délimitent entre elles un logement ayant une forme et des dimensions correspondant à celles de la section transversale du capuchon à recevoir. L'utilisation de ce dispositif est extrêmement simple: comme représenté en figure 2, il suffit d'introduire un dispositif 10 selon l'invention ou un ca¬ puchon classique de conditionnement, du côté opposé à son extrémité ouverte, dans l'organe de prise et de maintien 16 d'un autre dispositif 10 selon l'invention, et de faire coulisser ce premier dispositif ou ce premier capu¬ chon dans l'organe de prise et de maintien 16 du second dispositif jusqu'à ce qu'il soit retenu fermement par cet organe 16, en raison de la déformation élastique de ce dernier. Une personne peut alors tenir l'ensemble ainsi formé par un des capuchons 10 et introduire une aiguille 20 montée en bout d'une seringue dans l'autre des capu¬ chons 10, sans risque de se piquer les doigts. La surface interne du collet d'extrémité 14 du capuchon 10 est prévue pour immobiliser en rotation la bague 22 de montage de l'aiguille 20 sur la seringue. Ainsi, lorsque l'aiguille est introduite complètement dans le capuchon 10, et que sa bague de montage 22 est immobilisée en rotation à l'intérieur du collet 14 du ca¬ puchon, il suffit d'une rotation de la seringue pour la désolidariser de l'aiguille qui reste alors à l'intérieur du capuchon 10. On peut ensuite replacer sur le collet 14 le bouchon de fermeture du capuchon 10, et jeter le capu¬ chon contenant l'aiguille, après avoir sorti ce capuchon de l'Organe de prise et de maintien 16 de l'autre dispo¬ sitif.The gripping and holding member 16 consists of two elastically deformable lugs 18, forming clamps or clamping jaws. These two tabs 18 delimit between them a housing having a shape and dimensions corresponding to those of the cross section of the cap to be received. The use of this device is extremely simple: as shown in FIG. 2, it suffices to introduce a device 10 according to the invention or a conventional packaging cap, on the side opposite its open end, into the gripping and holding 16 of another device 10 according to the invention, and sliding this first device or this first capu¬ chon in the gripping and holding member 16 of the second device until it is firmly retained by this member 16, due to the elastic deformation of the latter. A person can then hold the assembly thus formed by one of the caps 10 and introduce a needle 20 mounted at the end of a syringe into the other of the caps 10, without the risk of pricking their fingers. The internal surface of the end collar 14 of the cap 10 is provided to immobilize in rotation the ring 22 for mounting the needle 20 on the syringe. Thus, when the needle is fully inserted into the cap 10, and its mounting ring 22 is immobilized in rotation inside the collar 14 of the cap, it suffices to rotate the syringe to detach from the needle which then remains inside the cap 10. We can then replace on the collar 14 the cap closure cap 10, and discard the capu¬ chon containing the needle, after removing this cap from the 'Gripping and holding member 16 of the other device.
Dans la variante de réalisation représentée en figure 3, le capuchon 10 du dispositif selon l'invention a une section transversale à contour extérieur polygonal, par exemple hexagonal, et l'organe 16 de prise et de maintien prévu à l'extrémité fermée du capuchon délimite un logement à contour interne hexagonal correspondant au contour externe hexagonal du capuchon 10. Ainsi, lorsqu'un autre capuchon 10 est introduit dans cet organe de prise et de maintien 16, il est automatiquement immo¬ bilisé en rotation.In the variant embodiment shown in FIG. 3, the cap 10 of the device according to the invention has a cross section with a polygonal external contour, for example hexagonal, and the gripping and holding member 16 provided at the closed end of the cap delimits a housing with a hexagonal internal contour corresponding to the hexagonal external contour of the cap 10. Thus, when another cap 10 is introduced into this gripping and holding member 16, it is automatically immobilized in rotation.
Par ailleurs, l'aiguille 20 conditionnée dans ce dispositif peut être du type s'étendant de part et d'autre de la bague 22 de montage sur une seringue et se terminant par deux . extrémités pointues dont l'une 24 est utilisée pour injecter un produit à un patient et dont l'autre 26 est utilisée pour perforer un opercule de fer¬ meture d'un petit tube contenant le produit à injecter, ce petit tube étant logé à l'intérieur du corps de la se- ringue.Furthermore, the needle 20 packaged in this device can be of the type extending on either side of the ring 22 for mounting on a syringe and ending in two. pointed ends, one of which 24 is used to inject a product into a patient and the other of which 26 is used to puncture a closure of a small tube containing the product to be injected, this small tube being housed at the inside the syringe body.
Dans ce cas, lorsque cette aiguille est condi¬ tionnée dans le dispositif 10 de la figure 3, sa bague de montage 22 est logée à l'intérieur d'un prolongement tu¬ bulaire 28 du collet 14 du dispositif, et la partie de l'aiguille se terminant par la pointe 24 est à l'intérieur du capuchon 10, tandis que la partie opposée de l'aiguille comportant l'autre pointe 26 fait saillie à l'extérieur du dispositif et est recouverte normalement par un bouchon tubulaire 30 qui se monte sur le prolonge- ment 28 du collet 14 et vient en butée sur ce dernier. Le dispositif selon 1'invention peut alors comprendre un manchon tubulaire 32 qui est monté coulis¬ sant sur le capuchon 10 et le collet 14 et qui a une lon¬ gueur suffisante pour recouvrir et masquer complètement la partie de l'aiguille se terminant par la pointe 26,' lorsqu'il est poussé vers la droite en figure 3.In this case, when this needle is packaged in the device 10 of FIG. 3, its mounting ring 22 is housed inside a tubular extension 28 of the collar 14 of the device, and the part of the the needle ending in the tip 24 is inside the cap 10, while the opposite part of the needle comprising the other tip 26 protrudes outside the device and is normally covered by a tubular plug 30 which mounts on the extension 28 of the collar 14 and abuts on the latter. The device according to the invention can then comprise a tubular sleeve 32 which is slidably mounted on the cap 10 and the collar 14 and which has a length sufficient to cover and completely mask the part of the needle ending in the tip 26, ' when pushed to the right in Figure 3.
L'extrémité gauche de ce manchon 32 peut com¬ prendre un rebord ou un épaulement interne 34, formant butée sur le collet 14. Ce dispositif est utilisé de la façon sui¬ vante: lorsqu'on désire utiliser l'aiguille 20 logée dans le dispositif selon l'invention, on retire le bou¬ chon 30, on fait coulisser vers la droite le fourreau 32 pour masquer l'extrémité 26 de l'aiguille et on approche le dispositif d'une seringue dans laquelle a été placé un tube contenant le produit à injecter. Par l'extrémité 26 de l'aiguille, on perfore l'opercule de fermeture de ce tube, on fixe par exemple par vissage la bague 22 de l'aiguille sur la buse d'extrémité correspondante de la seringue, puis on retire le capuchon 10 pour laisser ap¬ paraître l'autre extrémité 24 de l'aiguille.The left end of this sleeve 32 can include a rim or an internal shoulder 34, forming a stop on the collar 14. This device is used in the following way: when it is desired to use the needle 20 housed in the device according to the invention, the plug 30 is removed, the sheath 32 is slid to the right to mask the end 26 of the needle and the device is approached with a syringe in which a tube containing is placed the product to be injected. By the end 26 of the needle, the closing cap of this tube is pierced, the ring 22 of the needle is fixed for example by screwing on the corresponding end nozzle of the syringe, then the cap is removed 10 to allow the other end 24 of the needle to appear.
Après l'injection du produit à un patient, on ramène le capuchon 10 sur l'extrémité 24 de l'aiguille, en tenant ce capuchon au moyen d'un autre dispositif se¬ lon l'invention et comme représenté en figure 2, on en¬ gage la bague 22 de l'aiguille à l'intérieur du prolonge¬ ment 28 du collet 14, on sépare l'aiguille de la seringue par rotation de cette dernière, on pose la seringue et on replace le bouchon 30 sur le prolongement 28 du collet 14 du dispositif, pour masquer l'extrémité 26 de l'aiguille.After injecting the product into a patient, the cap 10 is brought back to the end 24 of the needle, holding this cap by means of another device according to the invention and as shown in FIG. 2, engages the ring 22 of the needle inside the extension 28 of the collar 14, the needle is separated from the syringe by rotation of the latter, the syringe is placed and the cap 30 is replaced on the extension 28 of the collar 14 of the device, to mask the end 26 of the needle.
A ce moment, une piqûre accidentelle par la pointe 26 de l'aiguille reste toujours possible.At this time, an accidental puncture by the tip 26 of the needle is still possible.
On donne donc au corps 36 du bouchon 30 une section transversale identique à celle du capuchon 10 du dispositif selon l'invention, ce qui permet de monter le corps 36 du bouchon dans l'organe de prise et de maintien 16 d'un dispositif selon l'invention, pour le manipuler et le placer sur le prolongement 28 du capuchon 10 sans risque de piqûre par la pointe 26 de l'aiguille. La figure 4 représente une variante de réali-' sation du dispositif de la figure 3.The body 36 of the plug 30 is therefore given a cross section identical to that of the cap 10 of the device according to the invention, which makes it possible to mount the body 36 of the plug in the gripping and holding member 16 of a device according to the invention, for handling it and placing it on the extension 28 of the cap 10 without risk of puncture by the tip 26 of the needle. 4 shows an alternate embodiment 'tion of the device of Figure 3.
Dans cette variante de réalisation, les moyens de prise et de maintien comprennent au moins une patte 38 elastiquement deformable, qui s'étend le long du capuchon 10 sur une longueur relativement faible, par exemple à partir du collet 14 de celui-ci et en direction de l'extrémité fermée du capuchon.In this alternative embodiment, the gripping and holding means comprise at least one elastically deformable tab 38, which extends along the cap 10 over a relatively short length, for example from the collar 14 thereof and in direction of the closed end of the cap.
Dans l'exemple représenté en figure 4, le dis¬ positif comprend deux pattes 38 elastiquement défor- ables, qui sont diamétralement opposées.In the example shown in FIG. 4, the positive device comprises two elastically deformable legs 38 which are diametrically opposite.
Le bouchon 30 associé au capuchon 10 comprend également au moins une et par exemple deux pattes elasti¬ quement déformableε 40 de même type, qui s'étendent le long du corps 36 du bouchon en direction de son extrémité fermée.The plug 30 associated with the cap 10 also comprises at least one and for example two elastically deformable legs 40 of the same type, which extend along the body 36 of the plug in the direction of its closed end.
On utilise ce dispositif de la façon suivante: pour tenir un capuchon 10 dans lequel on dé¬ sire réintroduire une aiguille après utilisation, on prend un autre dispositif selon l'invention, du même type, on l'oriente perpendiculairement au capuchon 10 que l'on veut tenir et on engage une patte 38 de ce disposi¬ tif sous la patte 38 du capuchon 10 que l'on veut tenir, entre cette patte 38 et le capuchon 10 proprement dit.This device is used in the following manner: to hold a cap 10 in which one wishes to reintroduce a needle after use, one takes another device according to the invention, of the same type, it is oriented perpendicularly to the cap 10 than the 'We want to hold and we engage a tab 38 of this device under the tab 38 of the cap 10 that we want to hold, between this tab 38 and the cap 10 proper.
De même, pour tenir un bouchon 30 que l'on dé- sire replacer sur le capuchon 10 pour fermer son extré¬ mité ouverte, on introduit une patte 38 de l'autre dispo¬ sitif sous une patte 40 du bouchon 30.Likewise, to hold a plug 30 which one wishes to replace on the cap 10 to close its open end, a tab 38 of the other device is introduced under a tab 40 of the plug 30.
La figure 5 représente une autre variante de réalisation de l'invention, applicable notamment aux ai- guilles d'injection d'insuline qui se montent sur des systèmes réutilisables de dosage et d'injection automa¬ tiques.FIG. 5 shows another alternative embodiment of the invention, applicable in particular to the needles for injecting insulin which are mounted on reusable automatic dosing and injection systems.
Ces aiguilles sont du type s 'étendant de part et d'autre d'une bague de montage 42, comme l'aiguille représentée en figure 3, et leur partie 44 servant à l'injection de l'insuline est souvent recouverte d'un fourreau cylindrique 46 ayant un diamètre extérieur très faible (de l'ordre de 3 mm), l'ensemble aiguille-fourreau 46 étant recouvert d'un capuchon 48 dont l'extrémité ou- verte s'emboîte sur la bague 42 de montage de l'aiguille.These needles are of the type extending on either side of a mounting ring 42, like the needle shown in FIG. 3, and their part 44 used for the injection of insulin is often covered with a cylindrical sheath 46 having a very small external diameter (of the order of 3 mm), the needle-sheath assembly 46 being covered with a cap 48, the open end of which fits onto the ring 42 for mounting the needle.
Ces aiguilles sont en principe jetables après utilisation, mais certaines personnes les laissent mon¬ tées en permanence sur les système de dosage et d'injection automatiques et essayent après chaque injec- tion, de replacer le fourreau 46 sur la partie 44 de l'aiguille, ce qu'il est difficile de faire sans risquer de se piquer.These needles are in principle disposable after use, but some people leave them permanently mounted on the automatic dosing and injection system and try after each injection to replace the sheath 46 on the part 44 of the needle. , which is difficult to do without risking getting stung.
L'invention prévoit alors que 1'extrémité fer¬ mée du capuchon 48 est munie d'un organe 50 de prise et de maintien du fourreau 46, ce qui permet de ne pas tenir ce fourreau 46 avec les doigts, mais par l'intermédiaire du capuchon 48, lorsqu'on essaye de le replacer sur la partie 44 de l'aiguille.The invention then provides that the closed end of the cap 48 is provided with a member 50 for gripping and holding the sleeve 46, which makes it possible not to hold this sleeve 46 with the fingers, but through of the cap 48, when we try to replace it on the part 44 of the needle.
De façon générale, l'invention permet de mani- puler un capuchon ou un fourreau que l'on désire placer sur une aiguille ou dans lequel on souhaite introduire une aiguille, sans tenir ce capuchon ou ce fourreau di¬ rectement avec les doigts, ce qui évite les risques de piqûre involontaire par l'aiguille, et ce qui accroit de façon certaine la sécurité du personnel soignant. In general, the invention makes it possible to handle a cap or a sheath which it is desired to place on a needle or into which one wishes to introduce a needle, without holding this cap or this sheath directly with the fingers, which avoids the risks of involuntary needle sticking, and which certainly increases the safety of the nursing staff.
