Title (EN) APPARATUS FOR CONTROLLING CUFF PRESSURE IN AN ENDOTRACHEAL TUBE
(FR) APPAREIL DE REGULATION DE LA PRESSION DU MANCHON DANS UNE SONDE D'INTUBATION TRACHEALE
Abstract:
(EN) Apparatus (1) for controlling pressure in a cuff (2) of an endotracheal tube (3) comprises a pole mountable housing (25) within which an inflating medium supply pump (30) is located for supplying inflating medium to the cuff through a communicating tube (18) integral with the endotracheal tube (3) and a delivery tube (37) from the apparatus (1). A pressure transducer (28) connected to the endotracheal tube (3) by a connecting tube (29) monitors the pressure of the ventilating medium in the endotracheal tube (3) for determining transitions from the inspiratory to the expiratory phases of a breathing cycle. A microcontroller (27) controls the supply pump (30) for supplying the inflating medium to the cuff (2) at a first pressure level during the inspiratory phase of each breathing cycle and at a lower second pressure level during the expiratory phase of each breathing cycle.
(FR) L'invention concerne un appareil (1) de régulation de la pression dans un manchon (2) d'une sonde d'intubation (3) trachéale, comprenant un logement (25) pouvant être monté sur une tige et au sein duquel est située une pompe (30) d'alimentation en milieu de gonflage destinée à fournir un tel milieu au manchon via un tuyau de communication (18) intégré à la sonde (3) trachéale et un tuyau d'alimentation (37) provenant de l'appareil (1). Un transducteur de pression (28) relié à la sonde (3) trachéale par un tuyau de raccord (29) permet de surveiller la pression du milieu de ventilation dans la sonde (3) trachéale, et ce afin de déterminer des transitions entre phases d'inspiration et phases d'expiration, lors du cycle respiratoire. Un microcontrôleur (27) commande la pompe d'alimentation (30) afin qu'elle fournisse au manchon (2) le milieu de gonflage à un premier niveau de pression au cours de la phase d'inspiration de chaque cycle respiratoire, et à un second niveau de pression lors de la phase d'expiration de chaque cycle.
