Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

L'invention concerne un nouveau système perfectionné de protection lors de l'emploi d'aiguilles ou de seringues utilisées dans le monde médical. On conviendra dans la suite de ce texte d'utiliser le mot aiguille de Ubert (marque déposée). The invention relates to a new and improved protection system for the use of needles or syringes used in the medical field. It will be appropriate later in this text to use the word needle of Ubert (registered trademark).

"Il a été établi que les piqûres profondes avec les aiguilles creuses ayant servi à un abord vasculaire ou contenant du sang sont majoritairement en cause dans la transmission du V. I. H ou du H. C. V chez les soignants (circulaire DGS/DH nu 98/249 du 20 avril 1998).  "It has been established that deep punctures with hollow needles used for a vascular or blood-containing approach are mainly involved in the transmission of VI H or HC V in caregivers (circular DGS / DH n. 98/249). April 20, 1998).

Ces aiguilles correspondent aux aiguilles utilisées pour les sites implantés, servant à l'injection de solution ou pour le prélèvement du sang. Il s'agit d'aiguilles à ailette ou à ailettes. These needles correspond to the needles used for the implanted sites, used for the injection of solution or for the collection of blood. They are winged or finned needles.

Par site implanté, on entend que le système de site est implanté sous la peau du patient, le système permet tant des injectons multiples que des prélèvements sans endommager les veines du patient. Implanted site means that the site system is implanted under the skin of the patient, the system allows both multiple injections and samples without damaging the veins of the patient.

L'aiguille des site implantés est courbée, et forme généralement un angle de 90 , cette particularité rendant la mise en sécurité et la neutralisation de l'aiguille particulièrement difficile. Le nouveau système faisant l'objet de l'invention permet, dès la sortie de l'aiguille du site, sa neutralisation, et ce sans risque de piqûre pour l'infirmière ou le soignant. The needle of the implanted sites is curved, and generally forms an angle of 90, this feature making the setting security and the neutralization of the needle particularly difficult. The new system subject of the invention makes it possible, right out of the needle of the site, its neutralization, and this without risk of sting for the nurse or the caregiver.

Ont sait en effet que le risque de piqûre sur les sites implantés est des plus importants, ce risque provenant de l'effet rebond lors du retrait de l'aiguille de la chambre implantée. Have known indeed that the risk of sting on implanted sites is most important, this risk from the rebound effect when removing the needle from the implanted chamber.

La prévention des Accidents Exposants au Sang (AES) est aujourd'hui un souci majeur, tant sur le plan humain que fmancier auquel se doivent de répondre, ensemble, les professionnels du monde de la santé et leurs partenaires industriels. The prevention of Accidents Exposants au Sang (AES) is today a major concern, both human and financial, which must meet, together, professionals in the health sector and their industrial partners.

Le GERES a publié des recommandations qui permettent de définir un materièl de sécurité. Pour être considéré comme un matériel de sécurité, celui-ci doit intégrer les éléments suivants : Une mise en sécurité dès le retrait de l'aiguille, dans la continuité du geste. GERES has published recommendations for defining safety equipment. To be considered as a safety equipment, it must include the following elements: A security as soon as the withdrawal of the needle, in the continuity of the gesture.

Une activation uni manuelle, sans support. A uni manual activation without support.

Une mise en sécurité irréversible, avec un indicateur audible de mise en sécurité. An irreversible security setting, with an audible indicator of security.

Le système de protection qui fait l'objet de la présente invention pour les aiguilles de Ubert sur site implantés répond aux recommandations du GERES et vient compléter l'offre existante du produit sécurité ou d'aide à l'extraction des aiguilles de Ubert. The protection system which is the object of the present invention for implanted on-site Ubert needles meets the recommendations of GERES and complements the existing offer of the security product or help with the extraction of Ubert needles.

La figure 1 représente la tête d'une aiguille de Ubert et en coupe transversale la gaine de protection.  Figure 1 shows the head of a Ubert needle and in cross section the protective sheath.

La figure 2 représente la gaine de protection et sa fenêtre. Figure 2 shows the protective sheath and its window.

Les figures 3a, 3b, et 3c représente trois schémas illustrant une technique de manipulation. Figures 3a, 3b, and 3c show three diagrams illustrating a handling technique.

Le système selon l'invention est décrit dans la figure 1 ; il est équipé d'une gaine de protection (1) avec un profile (2) qui permet de faire coulisser et neutraliser l'aiguille dès sont retrait du site. La tête (10) de l'aiguille est profilée pour s'insérer dans le profilé. The system according to the invention is described in Figure 1; it is equipped with a protective sheath (1) with a profile (2) which makes it possible to slide and neutralize the needle as soon as the site is removed. The head (10) of the needle is profiled to fit into the profile.

Un clic sonore (ou tout"clic"équivalent) confirme le verrouillage de l'étui protecteur. A click sound (or any "click" equivalent) confirms the locking of the protective case.

Le système de verrouillage (3) rend la neutralisation de l'aiguille irréversible. The locking system (3) renders the neutralization of the needle irreversible.

Une fenêtre (4) placée sur le côté du profilé (2) permet de confirmer la mise en sécurité. A window (4) placed on the side of the profile (2) confirms the trip.

Le système protecteur de l'aiguille possède au moins deux surface plates (5) pour faciliter la préhension du profilé ou étui protecteur (1). The protective system of the needle has at least two flat surfaces (5) to facilitate the gripping of the profile or protective case (1).

Le profilé possède de préférence une embase (6) très large, permettant le maintien de la chambre lors de l'extraction de l'aiguille. The profile preferably has a base (6) very wide, allowing the maintenance of the chamber during the extraction of the needle.

La gaine protectrice (1) du système peut à titre d'exemple préféré être construite en Polypropylène ou de tout matériaux équivalent. The protective sheath (1) of the system may, as a preferred example, be constructed of polypropylene or any equivalent material.

Le système de protection de l'aiguille permet à l'infirmière ou le soignant de neutraliser l'aiguille après avoir procédé à l'injection ou au prélèvement. Voir aussi figure 2. The needle protection system allows the nurse or caregiver to neutralize the needle after injection or sampling. See also Figure 2.

La gaine protectrice (1) est formée par exemple par un profilé (2) en queue d'aronde ou tout autre profilé équivalent. The protective sheath (1) is formed for example by a profile (2) dovetail or other equivalent profile.

A l'intérieur du profilé (2) se trouvent au moins deux excroissances souple (3) qui permettent la formation du"clic"sonore et serviront au cran de blocage. Inside the profile (2) are at least two flexible protrusions (3) which allow the formation of the "click" sound and serve the locking notch.

L'embase du système (6) est de préférence en matière souple afin de protéger la peau du patient. Le système possède une surface plane (5) de préhension pour permettre son maintien lors de la mise en sécurité. The base of the system (6) is preferably of flexible material to protect the skin of the patient. The system has a flat surface (5) gripping to allow its maintenance during the trip.

Les figures 3a à 3c illustrent une technique de manipulation. Figures 3a to 3c illustrate a handling technique.

Dés l'injection effectuée, appliquer le profile du système de protection sur la tête de l'aiguille. De l'autre main saisir les ailettes avec le pouce et l'index. (fig 3a) Maintenir les ailettes et remonter l'aiguille à la verticale jusqu'à l'obtention d'un"clic". After the injection, apply the protection system profile to the needle head. On the other hand grasp the fins with thumb and forefinger. (fig 3a) Hold the fins and raise the needle vertically until you get a "click".

(fig 3b) Le"clic"en bout de course confirme la neutralisation de l'aiguille. Le système est alors verrouillé dans le profil protecteur. Eliminer l'aiguille selon la procédure en vigueur dans l'établissement. (fig 3c) (fig 3b) The "click" at the end of the stroke confirms the neutralization of the needle. The system is then locked in the protective profile. Dispose of the needle according to the procedure in force in the establishment. (fig 3c)
