Abstract

Dispositif portable pour hémodialyse. L'invention concerne un dispositif portable pour hémodialyse qui comporte un hémodialyseur (1) monté sur un circuit sanguin et relié par l'un de ses embouts dialysat (7) à un tuyau en plastique (8) relié à une pompe (9) qui est elle-même connectée à une membrane d'osmose inverse conditionnée en cartouche ou tout autre dispositif d'extraction d'eau (10) elle-même reliée au niveau de l'une de ses deux sorties d'une part à un sac pour le recueil du rejet (11) et d'autre part à un réservoir d'eau osmosée (12) lui-même relié à une pompe (13) connectée à sa sortie à un second tuyau (16) connecté à l'autre embout dialysat de l'hémodialyseur (15) et qui ferme ainsi le circuit. Sur le tuyau (14) reliant le réservoir d'eau osmosée (12) à la 15 pompe (13) sont montés via des électrovannes (19, 20) deux réservoirs remplies de solutions concentrées de bicarbonates de sodium pour l'un et de chlorure de calcium pour l'autre (17,18). Le dispositif fonctionne lors des séances d'épuration extrarénale de façon séquentielle sous le contrôle d'un boitier central (5) en alternant deux types de cycles. Un cycle de filtration isolée suivi d'un cycle d'échange aux bicarbonates puis un autre cycle de filtration isolée puis un second cycle d'échange au chlorure de calcium. Ces cycles se répètent dans le même ordre jusqu'à obtention du volume de rejet (11) désiré (en général 2 litres par 24 heures). Lors du cycle de filtration isolée et après remplissage du circuit sanguin par le sang du patient, une ultrafiltration est réalisée par la pompe (9) montée sur le tube plastique (8) connecté au premier embout dialysat (7) de l'hémodialyseur et l'ultrafiltrat est injecté dans la membrane d'osmose inverse ou tout autre procédé d'extraction d'eau (10). L'eau osmosée obtenue est recueillie dans un réservoir (12). Le reliquat du filtrat résiduel appelé rejet est aussi recueilli dans un sac (11) et destiné à être jeté. L'eau osmosée est véhiculée par une seconde pompe (13) à travers un tuyau (16) relié au second embout (15) de l'hémodialyseur et injecté dans ce dernier. Cette première phase est suivie d'un temps de stase au cours duquel les différents composants du circuit dialysat sont au repos sous le contrôle du boitier central (5). Le cycle de diffusion aux bicarbonates est enclenché après ce temps de stase et se déroule selon le même schéma précédemment décrit à l'exception de de la dernier étape d'injection d'eau osmosée sous l'action de la deuxième pompe (13) au cours de laquelle cette eau est mélangée à la solution concentrée de bicarbonates de sodium contenue dans le résrvoir destiné à cet effet (17). La solution résultante est injectée dans l'hémodialyseur (1) et un temps de stase s'en suit. Un deuxième cycle de filtration isolée est alors enclenché suivi d'un temps de stase. Le cycle de diffusion au calcium est alors enclenché. Il se déroule selon le même schéma précédemment décrit à l'exception de de la dernier étape d'injection d'eau osmosée sous l'action de la deuxième pompe (13) au cours de laquelle cette eau est mélangée à la solution concentrée de chlorure de calcium contenue dans le réservoir (18). Le boitier central (5) contôle les différents systèmes impliqués dans le fonctionnement et la sécurité des circuits sanguins et dialysat du dispositif. Figure pour l'abrégé: fig 1Portable device for hemodialysis. The invention relates to a portable device for hemodialysis comprising a hemodialyzer (1) mounted on a blood circuit and connected by one of its dialysate nozzles (7) to a plastic tube (8) connected to a pump (9) which is itself connected to a reverse osmosis membrane packaged in a cartridge or any other water extraction device (10) itself connected at one of its two outlets on the one hand to a bag for the collection of the reject (11) and on the other hand to a reverse osmosis water tank (12) itself connected to a pump (13) connected at its outlet to a second pipe (16) connected to the other dialysate nozzle of the hemodialyzer (15) and which thus closes the circuit. On the pipe (14) connecting the osmosis water tank (12) to the pump (13) are mounted via solenoid valves (19, 20) two tanks filled with concentrated solutions of sodium bicarbonates for one and chloride calcium for the other (17,18). The device operates during extrarenal purification sessions sequentially under the control of a central box (5) by alternating two types of cycles. An isolated filtration cycle followed by a bicarbonate exchange cycle then another isolated filtration cycle followed by a second calcium chloride exchange cycle. These cycles are repeated in the same order until the desired reject volume (11) is obtained (generally 2 liters per 24 hours). During the isolated filtration cycle and after filling the blood circuit with the patient's blood, ultrafiltration is carried out by the pump (9) mounted on the plastic tube (8) connected to the first dialysate tip (7) of the hemodialyzer and the The ultrafiltrate is injected into the reverse osmosis membrane or other water extraction process (10). The osmosis water obtained is collected in a tank (12). The remainder of the residual filtrate called reject is also collected in a bag (11) and intended to be discarded. The osmosis water is conveyed by a second pump (13) through a pipe (16) connected to the second end piece (15) of the hemodialyzer and injected into the latter. This first phase is followed by a stasis time during which the various components of the dialysate circuit are at rest under the control of the central box (5). The bicarbonate diffusion cycle is started after this stasis time and takes place according to the same diagram previously described with the exception of the last step of injection of osmosis water under the action of the second pump (13) at the during which this water is mixed with the concentrated solution of sodium bicarbonate contained in the tank intended for this purpose (17). The resulting solution is injected into the hemodialyzer (1) and a stasis time follows. A second cycle of isolated filtration is then initiated followed by a period of stasis. The calcium diffusion cycle is then initiated. It takes place according to the same scheme described above with the exception of the last step of injection of osmosis water under the action of the second pump (13) during which this water is mixed with the concentrated chloride solution. of calcium contained in the reservoir (18). The central box (5) controls the various systems involved in the operation and safety of the blood circuits and dialysate of the device. Figure for the abstract: fig 1
