Abstract

L'invention concerne la fabrication de tubulures pour perfusion intraveineuse Un appareil 10 comporte un organe intermédiaire 32 permettant l'accès éventuel de l'air et pouvant être relié à un second appareil pour perfusion. Pour éviter l'aspiration d'air par l'organe intermédiaire une portion du tuyau d'écoulement en aval de l'organe intermédiaire a un diamètre interne rétréci calculé de façon que la pression des gouttes en amont de l'organe intermédiaire soit toujours inférieure à la pression en aval de cet organe dans des conditions d'utilisation normale. Application notamment aux appareils médicaux pour perfusion intraveineuse.
