Abstract

Le dispositif comprend un thermostat à infusion et un réchauffeur électrique qui se présente comme un bloc isolé. La partie amovible (1) du thermostat comprend une cavité creuse qui est rempli d'un caloporteur (8). On utilise en tant que caloporteur (8) un alliage de substances à haut poids moléculaire. Le point de fusion du caloporteur est égal à la température jusqu'à laquelle est chauffée la préparation. 5 minutes avant le début de la procédure, on chauffe le caloporteur (8) avec un réchauffeur électrique éloigné du patient. Après quoi, on place dans la partie amovible (1) du thermostat une partie chauffée du tuyau (6) du système d'infusion. Pendant l'infusion la préparation est chauffée grâce à la chaleur qui se dégage lors du durcissement de la masse en fusion. La température de la préparation préchauffée à n'importe quelle vitesse d'infusion est égale au point de fusion du caloporteur (8) qui reste inchangée depuis le début et jusqu'à la fin de la procédure. L'invention permet d'assurer la sécurité des procédures, d'améliorer lesur efficacité thérapeutique et économique.
