Abstract

Security system comprises a truncated conical holder of a supple material with a clip to retain the needle cover while the cover is being removed or replaced, contained in a housing (1) which makes it portable and stable. The same housing is equipped with treated and hardened electrodes (5), e.g. nickel or palladium coated, connected to a battery so they can destroy a syringe needle by fusion at both ends. During use and re-use the syringe needle cover is placed in the truncated conical holder; after use the needle is inserted between the electrodes and fused.

Description

ApPareil de sécurité fonctionnelle autour de l'acte d'iniection
dentaire
Indications du domaine technique
L'appareil est constitué de deux éléments Un "system block" qui retient le capuchon d'origine des aiguilles d'injections vissées sur
les seringues et qui permet en conséquence de décapuchonner et recapuchonner cette même
aiguille d'une seule main.Functional safety device around the act of injection
dental
Technical information
The device consists of two elements A "system block" which retains the original cap of the injection needles screwed onto
syringes and which therefore allows to cap and recap this same
needle with one hand.

Un système basé sur l'effet joule qui permet la fusion des deux parties métallique qui
constituent la particularité de l'aiguille dentaire.A system based on the joule effect which allows the fusion of the two metallic parts which
constitute the peculiarity of the dental needle.

Etat de la technique
Le procédé a été développé pour éliminier les risques liés au cours des différentes manipulations autour de l'acte d'injection. Ces risques sont encourus à cause de la particularité de l'aiguille dentaire, de sa protection, et du mode d'injection: 1 - Particularité de l'aiguille dentaire:
L'aiguille dentaire est constituée de deux parties métalliques opposées piquantes.State of the art
The process has been developed to eliminate the risks associated with the various manipulations around the act of injection. These risks are incurred because of the particularity of the dental needle, its protection, and the mode of injection: 1 - Particularity of the dental needle:
The dental needle is made up of two opposite sharp metal parts.

Une partie métallique qui sert à la pénétration dans les tissus humains, I'autre partie métallique
qui sert à pénétrer une carpule (dose médicamenteuse prédosée dans un tube de verre cellé et
stérile) qui contient le produit à diffuser et qui est préalablement placé dans la seringue.A metallic part which is used for penetration into human tissues, the other metallic part
which is used to penetrate a carpule (predosed drug dose in a cell glass tube and
sterile) which contains the product to be diffused and which is previously placed in the syringe.

L'aiguille dentaire se fixe sur la seringue qui supporte la carpule par vissage L'aiguille dentaire possède à l'origine deux capuchons de protection qui protègent les deux
parties métalliques piquantes.The dental needle attaches to the syringe which supports the cartridge by screwing The dental needle originally has two protective caps which protect both
pungent metal parts.

2 - Particularité du mode d'iniection et de protection de l'aiguille:
La plupart du temps une injection dans le domaine dentaire se pratique en plusieurs étapes avec des phases d'attente. Pour éviter le risque de blessure lors de cette phase d'attente le praticien ou le personnel soignant recapuchonnent l'aiguille avec leurs mains avec comme seul moyen de sécurité leur vigilance qui n'empêche pas certaines fois l'accident.2 - Special features of the needle injection and protection mode:
Most of the time an injection in the dental field is practiced in several stages with waiting phases. To avoid the risk of injury during this waiting phase, the practitioner or the nursing staff recap the needle with their hands with vigilance as the only means of safety, which does not prevent the accident sometimes.

Quoi qu'il en soit, dans l'acte qui suit la procédure d'injection ont doit obligatoirement dans un premier temps recapuchonner l'aiguille pour la désolidariser de la seringue en la dévissant puis dans un deuxième temps de procéder au capuchonnage de l'autre extrémité, il est à noter que chaque manipulation représente un risque pour l'exécutant.Anyway, in the act which follows the injection procedure, we must first recap the needle to detach it from the syringe by unscrewing it and then secondly proceed to cap the other end, it should be noted that each manipulation represents a risk for the performer.

A ce jour, aucun système n'a apporté une solution au problème du recapuchonnage de l'aiguille dentaire entre deux injections. En ce qui concerne le traitement de l'aiguille après injection, un certain nombre d'invention concerne des boites de stockage d'aiguilles qui fonctionnent par désolidarisation de l'aiguille. Ces systèmes sont strictement réservés aux aiguilles qui sont maintenues sur le seringue sans vissage. To date, no system has provided a solution to the problem of recapping the dental needle between two injections. With regard to the treatment of the needle after injection, a certain number of invention relates to boxes for storing needles which operate by separation of the needle. These systems are strictly reserved for needles which are held on the syringe without screwing.

D'autres systèmes d'incinération d'aiguilles agissent par électro-fusion permettant de détruire l'aiguille, et de la désolidariser et d'en stocker la partie résiduelle dans un réceptacle interne à -l'appareil (Brevet n" EP 0136392).Other needle incineration systems act by electro-fusion making it possible to destroy the needle, to separate it and to store the residual part in a receptacle internal to the device (Patent no. EP 0136392) .

Ces différents systèmes ne prennent pas en compte les aiguilles vissées, les aiguilles à deux extrémités piquantes, la protection autour de l'acte spécifique d'injection dentaire.These different systems do not take into account screwed needles, needles with two prickly ends, protection around the specific act of dental injection.

L'invention
L'invention repose sur un appareil de sécurité fonctionnelle autour de l'acte d'injection dentaire constitué de deux éléments: le "System Block" qui permet par sa forme conique, son élasticité et son positionnement vertical dans un support stable d'assurer le bloquage du capuchon d'aiguille de différents diamètres. De décapuchonner ou de recapuchonner l'aiguille vissée sur la seringue et ceci d'une seule main
Un système autonome de fusion par effet joule composé d'électrodes traitées et durcit qui
permet la fusion des aiguilles aux deux extrémités. Ce système de fusion qui fonctionne sur
batterie rechargeable autorise une totale mobilité de l'appareil au cours de son utilisation.The invention
The invention relies on a functional safety device around the act of dental injection consisting of two elements: the "System Block" which allows by its conical shape, its elasticity and its vertical positioning in a stable support to ensure the locking the needle cap of different diameters. To cap or recap the needle screwed on the syringe and this with one hand
An autonomous system of fusion by Joule effect composed of electrodes treated and hardens which
allows the needles to merge at both ends. This fusion system that works on
rechargeable battery allows total mobility of the device during its use.

L'ensemble "System Block" associé au système de fùsion est un ensemble homogène pour la sécurité fonctionnelle autour de l'acte d'injection.The "System Block" assembly associated with the fusion system is a homogeneous assembly for functional safety around the act of injection.

ExDosé détaillé
L'appareil se compose:
D'un boitier n"l suffisamment stable lesté par la batterie n" 2, pesant de l'ordre de 500 grammes afin d'être assez lourd pour être stable et suffsament léger pour tenir sur un plateau dentaire.ExDose detailed
The device consists of:
A case n "l sufficiently stable weighted by the battery n" 2, weighing around 500 grams in order to be heavy enough to be stable and light enough to hold on a dental tray.

Le "System Block" est composé d'un tube n" 3 de diamètre 10 mm et de 60 mm de longueur, étranglé en son centre par un clip de serrage n" 4 créant une structure conique de 10 à 20 d'angle.The "System Block" is composed of a tube n "3 with a diameter of 10 mm and a length of 60 mm, choked in its center by a clamping clip n" 4 creating a conical structure from 10 to 20 of angle.

Le tube conique permet un serrage par friction sans blocage pour les différents diamètres de capuchons n 6 et nO 8 existants sur le marché (de 4 à 10 mm) pouvant se visser sur la seringue n" 7.The conical tube allows frictionless clamping without blocking for the different cap diameters n 6 and nO 8 existing on the market (from 4 to 10 mm) which can be screwed onto syringe n "7.

Le diamètre au niveau de l'étranglement étant de 4 mm.The diameter at the throttle being 4 mm.

Un système de fusion qui se compose de 2 électrodes traitées au nickel et paladium ou or fin permet d'assurer le contact électrique des aiguilles dentaires qui provoquent un champ électrique de haute intensité qui nécessite des électrodes spécifiques, traitées et résistant à 12000 avec un courant de pointe de 200 ampères. L'utilisation d'électrodes non traitées pour des aiguilles dentaires rend rapidement l'appareil innopérent par un dépôt de calamine sur l'électrode d'où la nécessité d'électrodes spécifiques traitées. Les électrodes n" 5 sont reliées à un système de batteries spécifiques au plomb, seules capables de générer des courants de l'ordre de 200 ampères en pointe et d'assurer une autonomie de l'appareil.A fusion system which consists of 2 electrodes treated with nickel and paladium or fine gold ensures the electrical contact of dental needles which cause a high intensity electric field which requires specific electrodes, treated and resistant to 12000 with a current. 200 amp peak. The use of untreated electrodes for dental needles quickly makes the device inoperative by a deposit of scale on the electrode hence the need for specific treated electrodes. The no. 5 electrodes are connected to a system of lead-specific batteries, the only ones capable of generating currents of the order of 200 amps at peak and ensuring autonomy of the device.

Le système de fusion de l'appareil utilise le principe à effet joule largement utilisé dans le domaine de la fusion de métaux conducteurs. C'est à partir de ce principe que la partie métallique de l'aiguille placée entre les deux électrodes subit un échauffement jusqu'à fusion. The device's fusion system uses the Joule effect principle widely used in the field of conductive metal fusion. It is from this principle that the metal part of the needle placed between the two electrodes undergoes heating until fusion.
