Abstract

Ventilateur de volume comprenant une série de modes d'opération intégrés destinés à fournir à un patient un courant de gaz respirables sous pression. Une série de dispositifs de réglages ajustables produisent chacun un signal de seuil individuel relié à un paramètre du courant de gaz. Des moyens de commutation de modes permettent la sélection d'au moins un signal de mode. Chaque signal de seuil est comparé avec un signal variable commun pour produire une série de signaux de commande. Au moins l'un des signaux de commande est choisi en accord avec le signal de mode choisi et ce signal de commande est appliqué à un système de soupapes qui contrôlent le courant de gaz vers le patient. De cette manière, les dispositifs de réglage peuvent être ajustés continuellement pour changer un ou plusieurs des signaux de seuil sans faire varier l'un quelconque des autres signaux de seuil. En outre, il est prévu un systeme d'alarme inclus dans l'ensemble.A volume ventilator comprising a series of integrated operating modes for providing a flow of pressurized breathing gases to a patient. A series of adjustable adjustment devices each produce an individual threshold signal related to a parameter of the gas flow. Mode switching means allow the selection of at least one mode signal. Each threshold signal is compared with a common variable signal to produce a series of control signals. At least one of the control signals is chosen in accordance with the selected mode signal and this control signal is applied to a system of valves which control the flow of gas to the patient. In this way, the adjusters can be continuously adjusted to change one or more of the threshold signals without varying any of the other threshold signals. In addition, an alarm system is included in the set.
