Abstract

La présente invention concerne une pompe à perfusion avec laquelle une solution médicamenteuse peut être correctement administrée à un patient et dont la chaleur, produite pendant l'opération d'administration de la solution, n'a aucun effet sur une tubulure de perfusion ou sur la solution médicamenteuse passant dans la tubulure de perfusion. Cette pompe à perfusion (1) présente : un corps principal (2) ; une section de fixation de tubulure (50) permettant de fixer, dans le sens transversal, une tubulure de perfusion (200) pour injecter un médicament à un patient (P), la section de fixation de la tubulure (50) étant disposée à l'intérieur du corps principal (2) ; une section d'entraînement de l'introduction de la solution (60) permettant de mettre la tubulure de perfusion sous pression (200) et d'introduire le médicament à l'intérieur de la tubulure de perfusion (200) dans le sens transversal, dans un état où la tubulure de perfusion (200) a été fixée à la section de fixation de la tubulure (50), la section d'entraînement de l'introduction de la solution (60) étant disposée à l'intérieur du corps principal (2) ; un couvercle d'ouverture et de fermeture (5) permettant de fermer et donc de couvrir la tubulure de perfusion (200) fixée à la section de fixation de tubulure (50) ; et une section de source d'alimentation (720) permettant d'entraîner la section d'entraînement de l'administration de la solution (60). La section de source d'alimentation (720) est disposée au-dessus de la section d'entraînement de l'administration de la solution (60) à l'intérieur du corps principal (2).
