Abstract
Description
La présente invention concerne un dispositif pour le retrait des aiguilles à usage médical d'une chambre implantable pour perfusion (C.I.P.). The present invention relates to a device for the withdrawal of needles for medical use from an implantable chamber for infusion (C.I.P.).
Ces chambres de perfusions, implantées chirurgicalement sous la peau, se présentent sous la forme de boitiers fermés par une membrane de silicone et reliés au réseau vasculaire par un cathéter.These infusion chambers, surgically implanted under the skin, are in the form of cases closed by a silicone membrane and connected to the vascular network by a catheter.
L'injection de substances médicamenteuses dans le boitier se fait après traversée de la peau et de la membrane par l'aiguille à usage médical, droite ou courbe selon les cas.The injection of medicinal substances into the housing is done after crossing the skin and the membrane by the needle for medical use, straight or curved depending on the case.
Lors du retrait de l'aiguille de la chambre de perfusion, la membrane offre une résistance qui nécessite un maintien ferme de la chambre à travers la peau, par les doigts de 1V opérateur. When withdrawing the needle from the infusion chamber, the membrane offers resistance which requires that the chamber be held firmly through the skin by the fingers of the operator.
La présence de ces doigts, pratiquement au contact de l'aiguille est source de piqures ou de blessures, voire de contamination, lors de cette opération de retrait.The presence of these fingers, practically in contact with the needle, is a source of bites or injuries, or even contamination, during this removal operation.
Le dispositif selon l'invention permet de remédier à cet inconvenient en éloignant les doigts de l'opérateur tout en permettant un maintien ferme de la chambre de perfusion lors du retrait de l'aiguille à usage médical.The device according to the invention makes it possible to remedy this drawback by keeping the fingers of the operator away while allowing the infusion chamber to be held firmly when the needle for medical use is withdrawn.
Ce dispositif selon l'invention comporte une extrémité aplatie et fendue que l'on pose sur la peau en regard de la chambre implantable de perfusion, la fente permettant le passage et le retrait de l'aiguille à usage médical.This device according to the invention comprises a flattened and slotted end which is placed on the skin opposite the implantable infusion chamber, the slot allowing the passage and withdrawal of the needle for medical use.
La forme aplatie de l'extrémité du dispositif laisse un libre accès à l'aiguille pour son retrait par l'opérateur.The flattened shape of the end of the device leaves free access to the needle for its withdrawal by the operator.
Le manche du dispositif permet un éloignement de la main qui maintient, à travers la peau, la chambre implantable de perfusion. The handle of the device allows a distancing of the hand which maintains, through the skin, the implantable infusion chamber.
Les dessins annexés illustrent l'invention - la figure I représente de face le dispositif selon l'invention.The accompanying drawings illustrate the invention - Figure I shows the device of the invention from the front.
- la figure 2 représente de profil le même dispositif posé sur la peau en regard d'une chambre implantable pour perfusion vue en coupe.- Figure 2 shows in profile the same device placed on the skin opposite an implantable chamber for infusion seen in section.
En référence à ces dessins, le dispositif présente un manche (1) prolongé par une extrémité aplatie et fendue (2). With reference to these drawings, the device has a handle (1) extended by a flattened and slotted end (2).
L'extrémité fendue est posée au contact de la peau (3), en regard de la chambre (4), la fente permettant le passage et le libre retrait de l'aiguille à usage médical (5).The split end is placed in contact with the skin (3), facing the chamber (4), the slot allowing the passage and the free withdrawal of the medical needle (5).
A titre d'exemple non limitatif le dispositif aura une dimension totale de l'ordre de 15 à 20 centimètres, l'extrémité aplatie un diamètre de l'ordre de 4 à 5 centimètres et sa fente une longueur de l'ordre de 1 à 2 centimètres.By way of nonlimiting example, the device will have a total dimension of the order of 15 to 20 centimeters, the flattened end a diameter of the order of 4 to 5 centimeters and its slot a length of the order of 1 to 2 centimeters.
Le matériau composant ce dispositif devra être stérilisable, restérilisable ou à usage unique.The material making up this device must be sterilizable, re-sterilizable or disposable.
Le dispositif selon l'invention est particulièrement recommandé pour le retrait des aiguilles à usage médical des chambres implantables pour perfusions lorsqu'il existe des risques de contamination. The device according to the invention is particularly recommended for the withdrawal of needles for medical use from implantable chambers for infusions when there are risks of contamination.
