Abstract

The equipment has a rigid reservoir (1a) including a sliding piston (1b) assuring sealing between a volume (1e) and another volume that are situated on both sides of the piston with respect to the reservoir. One of the volumes is sealed and filled with air. The other volume is initially empty and filled with rinsing liquid during its utilization via a calibrated orifice (1d) such that flowrate of the liquid is less during draining, to obtain slight compensation injection for permitting a nurse to withdraw a chemotherapy needle from an oncology chamber without suction effect.

Description

Lors du retrait d'une aiguille de chimiothérapie, le souci principal du personnel soignant est l'inconvénient que provoque ce retrait. Le phénomène d'aspiration est dû à la masse de l'aiguille qui quitte progressivement la chambre implantée ainsi qu'à la forme coudée de l'aiguille de Huber qui a tendance à augmenter artificiellement le volume de ladite chambre. When removing a chemotherapy needle, the main concern of the caregiver is the inconvenience this withdrawal causes. The suction phenomenon is due to the mass of the needle that gradually leaves the implanted chamber and the bent shape of the Huber needle which tends to artificially increase the volume of said chamber.

Ce mouvement ne peut être trop rapide sous peine de rendre ce geste douloureux, et la délicatesse avec laquelle il est provoqué, permet à l'infirmière d'éviter cette douleur mais complète largement le phénomène d'aspiration à l'extrémité du cathéter, aspiration provoquée par le retrait de l'aiguille de Huber de la chambre dans laquelle celle-ci a été implantée. This movement can not be too fast or painful, and the delicacy with which it is caused, allows the nurse to avoid this pain but largely complements the phenomenon of aspiration at the end of the catheter, suction caused by the removal of the Huber needle from the chamber in which it was implanted.

Actuellement l'état de l'art, connu et opposé pour ce type de problème, n'est semble-t-il représenté que par le brevet US 2006/015085 de BAIES Marc dont le dispositif comporte un matériel de type pistolet utilisant une aiguille incluse dans un cathéter et destiné à la fois à contrôler la profondeur de l'injection et le retrait de l'aiguille pour éventuellement assurer la diffusion du produit injecté et d'autre- part le brevet US 2003/114799 CHEIK ROLAND CHERIF, qui comporte une véritable seringue, prolongée par un dispositif englobant la longueur de l'aiguille qui sera recouverte le moment venu par le prolongement de cette seringue spéciale; tous deux ne présentant pas de similitudes spécifiques avec le produit présenté Il nous a donc semblé intéressant d'essayer de supprimer différemment ce problème d'aspiration en essayant de compenser ce volume qui disparaît de la chambre. Currently the state of the art, known and opposed to this type of problem, is apparently only represented by the US patent 2006/015085 of Marc BERIES whose device comprises a gun-type material using a needle included in a catheter and intended both to control the depth of the injection and the withdrawal of the needle to possibly ensure the diffusion of the injected product and also US 2003/114799 CHEIK ROLAND CHERIF, which comprises a real syringe, extended by a device including the length of the needle that will be covered when the time comes by the extension of this special syringe; both of them do not have specific similarities with the product presented. So it seemed interesting to try to remove this suction problem differently by trying to compensate for this volume which disappears from the chamber.

La compensation de cette aiguille qui quitte la chambre pourrait provenir d'un élément extérieur à celle-ci, tel un liquide, qui injecté dans la chambre, pendant la manoeuvre de retrait de l'aiguille, viendrait donc compenser le volume retiré et ne provoquerait donc pas d'aspiration à l'extrémité du cathéter implanté, source d'ennui majeur pour le patient, telle l'aspiration de sang qui se coagule à l'intérieur dudit cathéter. The compensation of this needle that leaves the chamber could come from an element external to it, such as a liquid, which injected into the chamber, during the withdrawal maneuver of the needle, would therefore compensate for the volume removed and would not cause therefore no suction at the end of the implanted catheter, major source of boredom for the patient, such as suction of blood that coagulates inside said catheter.

Il pourrait s'agir d'un dispositif tel un réservoir-0.a Figure 1} muni d'un piston coulissant{ib Figure 1} à l'intérieur de celui-ci. Le réservoir sera raccordé à un dispositif de raccordement normalisé, {ic Figure» du genre cône ou verrou américain, et dont le volume intérieur serait nettement supérieur à celui nécessaire à l'injection de compensation du phénomène d'aspiration constaté, Ce réservoir sera muni d'un dispositif d'action tel un piston pouvant être mobilisé à l'intérieur de celui-ci. Le piston placé en position basse, {lb Figurel}c'est-à-dire près de la sortie du liquide dont il sera rempli, Le réservoir, quant à lui s'il ne l'est déjà lors de sa fabrication, sera bouché de façon étanche à l'autre extrémité, ce qui le laissera donc dans un état rempli d'air, donc compressible.{1eFigurel} Le piston coulissant {1bFigurel}se trouvant à l'intérieur du réservoir permettra d'obtenir une étanchéité parfaite entre les deux chambres distinctement formées par sa présence y compris pendant son déplacement, dans un sens ou dans l'autre à l'intérieur du réservoir rigide. It could be a device such as a tank-0.a Figure 1} provided with a sliding piston {ib Figure 1} inside thereof. The tank will be connected to a standardized connection device, such as the American cone or lock, and whose internal volume would be much greater than that required for the compensation injection of the suction phenomenon observed. an action device such as a piston that can be mobilized inside thereof. The piston placed in the lower position, {lb Figurel} that is to say near the exit of the liquid which will be filled, The tank, meanwhile if it is already in its manufacture, will be plugged at the other end, which will leave it in a state filled with air, therefore compressible. {1eFigurel} The sliding piston {1bFigure} located inside the tank will make it possible to obtain a perfect seal between the two chambers distinctly formed by its presence including during its displacement, in one direction or the other inside the rigid tank.

Et c'est tout d'abord le temps de remplissage de liquide dudit réservoir dont le piston se trouve primitivement près de l'orifice normalisé de type cône Luer ou Verrou américain dit Luer Lok {lb Figurel} suivi du maintien en l'état durant son adaptation au cathéter relié à l'aiguille, au moyen d'un clamp ou d'un robinet {2c Figure2}; ce réservoir sera pourvu d'un orifice de remplissage et/ou sortie du liquide , suffisamment réduit, ce qui, malgré la pression dans la partie haute du réservoir, provoquera une vidange lente de la partie basse du réservoir rempli de liquide de rinçage, pour permettre à la personne chargée des soins d'avoir suffisamment de temps pour effectuer la manoeuvre de retrait de l'aiguille de chimiothérapie, sans provoquer d'aspiration à l'extrémité du catheter implanté. And it is first of all the liquid filling time of said tank, the piston of which is originally near the standardized orifice of the Luer cone type or American bolt called Luer Lok {lb Figurel} followed by the maintenance in the state during its adaptation to the catheter connected to the needle, by means of a clamp or a tap {2c Figure2}; this tank will be provided with a filling orifice and / or liquid outlet sufficiently reduced, which, despite the pressure in the upper part of the tank, will cause a slow emptying of the lower part of the tank filled with rinsing liquid, for allow the caregiver sufficient time to perform the chemotherapy needle withdrawal maneuver, without causing suction at the end of the implanted catheter.

On constatera que pendant le cycle de remplissage de la partie dite basse dudit réservoir{1bFigurel}, par un matériel adapté telle la seringue précédemment utilisée pour le rinçage primitif, le piston reculera {2gFigure2}d'un volume égal au volume du liquide injecté ; on veillera à ce que la quantité de liquide injectée dans la partie basse du réservoir au moment du recul du piston coulissant soit nécessaire et suffisante pour, qu'en rapport à la taille de l'orifice de sortie du liquide,{idFigurel} l'infirmière puisse avoir suffisamment de temps pour effectuer la manoeuvre de retrait de l'aiguille de chimiothérapie, sans provoquer d'aspiration à l'extrémité du cathéter implanté. It will be noted that during the filling cycle of the so-called lower portion of said reservoir {1bFigure}, by suitable equipment such as the syringe previously used for primitive rinsing, the piston will retreat {2gFigure2} by a volume equal to the volume of the injected liquid; it will be ensured that the quantity of liquid injected into the lower part of the reservoir at the time of the retraction of the sliding piston is necessary and sufficient so that, in relation to the size of the outlet orifice of the liquid, {idFigurel} the The nurse may have sufficient time to perform the withdrawal maneuver of the chemotherapy needle without causing suction at the end of the implanted catheter.

Pendant ce temps, l'air emprisonné de façon étanche dans la chambre arrière, se trouvera de plus en plus comprimé jusqu'à ce que le niveau du piston atteigne le niveau choisi par le fabricant.{2a,2d,2eFigure2} Ce peut être une butée, un repère visuel etc..{2fFigure2} Le volume d'air initial, dans la partie haute du réservoir, comprimé, sera nécessaire et suffisant pour, qu'en rapport à l'orifice de sortie du liquide l'infirmière puisse avoir suffisamment de temps pour effectuer la manoeuvre de retrait de l'aiguille de chimiothérapie, sans provoquer d'aspiration à l'extrémité du cathéter implanté. During this time, air trapped tightly in the rear chamber will be more and more compressed until the piston level reaches the level chosen by the manufacturer. {2a, 2d, 2eFigure2} It can be an abutment, a visual cue, etc .. {2fFigure2} The initial volume of air, in the upper part of the reservoir, compressed, will be necessary and sufficient for, that in relation to the outlet of the liquid the nurse can have sufficient time to perform the withdrawal maneuver of the chemotherapy needle, without causing suction at the end of the implanted catheter.

Le réservoir de compensation étant rempli, l'utilisatrice pourra alors fermer la voie de communication d'avec le dispositif de remplissage au moyen d'un robinet 3 voies par exemple, et le raccorder à la tubulure reliée à l'aiguille de traitement de chimiothérapie. The compensation reservoir being filled, the user can then close the communication channel with the filling device by means of a 3-way valve, for example, and connect it to the tubing connected to the chemotherapy treatment needle. .

Ceci fait il suffira alors, juste avant de procéder au retrait de l'aiguille, d'ouvrir à nouveau le robinet du réservoir pour que celui-ci se vide dans la tubulure. En effet l'air comprimé lors du remplissage, dans la partie arrière du dispositif, aura tendance à se détendre, comme c'est le cas dans un moteur à explosion ou un compresseur, et la poussée sur le piston provoquera donc la vidange du réservoir dans la tubulure donc la compensation de l'aspiration provoquée par le retrait de l'aiguille. Il faut donc que le volume d'air initial, dans la partie haute du réservoir, comprimé, soit nécessaire et suffisant pour, qu'en rapport à l'orifice de sortie du liquide l'infirmière puisse avoir suffisamment de temps pour effectuer la manoeuvre de retrait de l'aiguille de chimiothérapie, sans provoquer d'aspiration à l'extrémité du cathéter implanté.et il est nécessaire que la quantité de liquide injectée dans la partie basse du réservoir au moment du recul du piston coulissant soit nécessaire et suffisante pour, qu'en rapport à l'orifice de sortie du liquide, l'infirmière puisse avoir suffisamment de temps pour effectuer la manoeuvre de retrait de l'aiguille de chimiothérapie, sans provoquer d'aspiration à l'extrémité du cathéter implanté. This is enough then, just before removing the needle, to open the tank valve again so that it empties into the tubing. Indeed the compressed air during the filling, in the rear part of the device, will tend to relax, as is the case in an internal combustion engine or compressor, and the thrust on the piston will thus cause the emptying of the tank in the tubing thus the compensation of the suction caused by the withdrawal of the needle. It is therefore necessary that the initial volume of air, in the upper part of the reservoir, compressed, is necessary and sufficient for, that in relation to the liquid outlet orifice the nurse may have sufficient time to perform the maneuver removal of the chemotherapy needle, without causing suction at the end of the implanted catheter.and it is necessary that the amount of liquid injected into the lower part of the reservoir at the time of retreat of the sliding piston is necessary and sufficient to that with respect to the liquid outlet port, the nurse may have sufficient time to perform the withdrawal maneuver of the chemotherapy needle, without causing suction at the end of the implanted catheter.

Le réservoir étant réalisé dans une matière, rigide, transparente, permettra de contrôler , du fait de son remplissage, le déplacement du piston qui se trouve à l'intérieur, déplacement qui provoque une compression de l'air se trouvant dans la partie haute du cylindre dont le taux de compression augmentera au fur et à mesure du remplissage de la partie basse du réservoir par le liquide de rinçage Le réservoir pourra être muni d'une butée de déplacement du piston, ce qui servira d'indicateur visuel pour préciser que le volume nécessaire à la compensation nécessaire du liquide de rinçage a bien été atteint. The tank being made of a material, rigid, transparent, will control, because of its filling, the displacement of the piston which is inside, displacement which causes a compression of the air being in the upper part of the cylinder whose compression ratio will increase as filling of the lower part of the tank by the rinsing liquid The tank may be provided with a piston displacement stop, which will serve as a visual indicator to clarify that the volume necessary for the necessary compensation of the rinsing liquid has been achieved.

Le réservoir pourra être muni d'un repère de remplissage précisant ainsi au personnel soignant que le niveau suffisant de liquide a été atteint pour la fonction de compensation. The tank may be provided with a filling mark thus indicating to the nursing staff that the sufficient level of liquid has been reached for the compensation function.

Cette action permettra donc d'éviter le phénomène d'obstruction du cathéter décrit antérieurement, obstruction très préjudiciable pour le patient. This action will therefore prevent the phenomenon of obstruction of the previously described catheter obstruction very detrimental to the patient.
