Description

Nouvelle aiguille pour dispositif médical et dispositif en comportant New needle for medical device and device comprising the same
La présente invention est relative à une nouvelle aiguille pour dispositif médical et dispositif en comportant.The present invention relates to a new needle for medical device and device comprising it.
Depuis plusieurs années, du fait notamment des maladies contagieuses telle que le SIDA et l'hépatite C, le personnel médical, hospitalier ou non, est très exposé à la contagion lors de la manipulation des aiguilles usagées.For several years, in particular due to contagious diseases such as AIDS and hepatitis C, medical personnel, whether hospital or not, have been very exposed to contagion when handling used needles.
Actuellement, il est préconisé de retirer l'aiguille après usage au moyen d'une boîte la recueillant afin d'éviter au personnel de se piquer en la manipulant. Mais ces dispositifs ne permettent pas d'assurer une sécurité totale en particulier contre tout contact accidentel avec le personnel entre le moment où l'aiguille est retirée du corps du patient et celui où elle est séparée du dispositif comme décrit précédemment ou celui où le dispositif avec l'aiguille est jeté dans une boîte spéciale destinée à cet effet.Currently, it is recommended to withdraw the needle after use by means of a box collecting it in order to avoid personnel being pricked while handling it. However, these devices do not ensure total security, in particular against any accidental contact with the personnel between the moment when the needle is withdrawn from the patient's body and when it is separated from the device as described above or when the device with the needle is thrown into a special box intended for this purpose.
Il sera rappelé qu'une aiguille de seringue, ou pour tout autre dispositif destiné à injecter un produit liquide dans un corps humain ou animal, doit présenter un certain nombre de qualités : en particulier elle doit avoir une extrémité libre très effilée afin de permettre une pénétration rapide, précise et aussi indolore que possible.It will be recalled that a syringe needle, or for any other device intended for injecting a liquid product into a human or animal body, must have a certain number of qualities: in particular it must have a very tapered free end in order to allow a quick, precise and as painless as possible.
Aussi un des buts de la présente invention est-il de fournir une aiguille à usage médical dont l'extrémité effilée ne présente, après usage, aucun risque de piqûre pour le personnel médical.One of the aims of the present invention is therefore to provide a needle for medical use, the tapered end of which presents, after use, no risk of puncture for medical personnel.
Un autre but de cette invention est de fournir une telle aiguille avec un prix de revient aussi faible que possible et concurrentiel.Another object of this invention is to provide such a needle with a cost price as low as possible and competitive.
Un but supplémentaire de l'invention est de fournir un dispositif médical qui est équipée d'une telle aiguille. Ces buts, ainsi que d'autres qui apparaîtront par la suite, sont atteints par une aiguille à usage médical, qui est caractérisée, selon la présente invention, par le fait qu'une des extrémités de cette aiguille est arrondie et est munie d'un embout effilé.A further object of the invention is to provide a medical device which is equipped with such a needle. These aims, as well as others which will appear subsequently, are achieved by a needle for medical use, which is characterized, according to the present invention, in that one of the ends of this needle is rounded and is provided with a tapered tip.
Avantageusement, cet embout effilé est réalisé en une matière inerte soluble dans les liquides corporels, tel qu'un sucre, un sel ou autre produit analogue.Advantageously, this tapered tip is made of an inert material soluble in body fluids, such as a sugar, a salt or the like.
La présente invention concerne aussi un dispositif médical, tel qu'une seringue ou un appareil de transfusion par exemple, qui comporte une aiguille telle que définie ci-dessus.The present invention also relates to a medical device, such as a syringe or a transfusion device for example, which comprises a needle as defined above.
La description qui va suivre et qui ne présente aucun caractère limitatif, permettra à l'homme du métier de mieux comprendre la mise en œuvre de la présente invention ainsi que ces avantages.The description which follows and which is in no way limiting, will enable those skilled in the art to better understand the implementation of the present invention as well as these advantages.
Une aiguille à usage médicale selon la présente invention comporte un corps généralement en métal tel que del'aluminium et est munie d'un canal dans son axe pour permettre le passage du liquide à injecter. Son extrémité libre, ou extrémité distale puisque la plus éloignée par rapport au dispositif sur lequel l'aiguille est montée, est munie selon la présente invention d'un embout effilé.A needle for medical use according to the present invention comprises a body generally made of metal such as aluminum and is provided with a channel in its axis to allow the passage of the liquid to be injected. Its free end, or distal end since the most distant from the device on which the needle is mounted, is provided according to the present invention with a tapered end.
Cet embout effilé est constitué en un matériau inerte, c'est-à-dire qui ne réagit ni avec les liquides à injecter ni avec les constituants du corps humain et/ou animal, et est très rapidement soluble dans les liquides corporels. Ainsi, un tel embout peut-il être réalisé en un sucre, un sel ou tout autre produit analogue, qui résiste aux températures de stérilisation : cette aiguille, comme tout matériel médical, doit être stérilisée avant usage.This tapered tip is made of an inert material, that is to say which reacts neither with the liquids to be injected nor with the constituents of the human and / or animal body, and is very quickly soluble in body fluids. Thus, such a tip can it be made of a sugar, a salt or any other similar product, which withstands sterilization temperatures: this needle, like all medical equipment, must be sterilized before use.
Pour réaliser une aiguille selon la présente invention, on met en œuvre les procédés connus de fabrication mais on supprime l'étape d'effilage : de ce fait l'extrémité distale de l'aiguille présente un bout arrondi ne présentant aucun risque pour le personnel.To make a needle according to the present invention, the known manufacturing methods are implemented but the taper step is omitted: therefore the distal end of the needle has a rounded tip presenting no risk to the personnel .
On dépose sur ce bout arrondi une goutte du matériau inerte qui se conforme en une goutte effilée, constituant l'embout effilé.Is deposited on this rounded end a drop of the inert material which conforms into a tapered drop, constituting the tapered tip.
Selon un mode de réalisation, l'aiguille à extrémité arrondie est trempée verticalement, le bout arrondi étant donc dirigé vers le bas, dans une solution chaude du matériau inerte : lors de la remontée, la goutte de matériau inerte qui est retenue, se conforme en une pointe acérée lors de sa solidification.According to one embodiment, the needle with rounded end is dipped vertically, the rounded end therefore being directed downward, in a hot solution of inert material: during the ascent, the drop of inert material which is retained, conforms in a sharp point during its solidification.
Lors de la piqûre proprement dite, que celle-ci soit sous-cutanée, intramusculaire ou intraveineuse, l'embout effilé joue exactement le même rôle qu'une extrémité effilée d'une aiguille, mais se dissout très rapidement dans les liquides corporels de telle sorte que le canal de l'aiguille est ouvert à cette extrémité de façon à permettre l'injection d'une substance. In the actual injection, whether it is subcutaneous, intramuscular or intravenous, the tapered tip plays exactly the same role as a tapered end of a needle, but dissolves very quickly in body fluids of such so that the needle channel is open at this end to allow the injection of a substance.
