Title (EN) FLOW CONTROL EQUIPMENT
(FR) DISPOSITIF DE COMMANDE DE DEBIT
Abstract: front page image
(EN)Anesthesia ventilator (10) for controlling the flow of air and/or oxygen through a plurality of binary weighted valves (34-38) from a fluid regulator source (27) to a bellows assembly (14). Directly-set minute volume, breath rate and inspiration to expiration ratio controls (11, 12, 13) operate electronic circuitry (23) which adjusts the magnitude of the flow, the tidal volume and the inhalation to exhalation times. The circuitry (23) includes alarm detecting devices (15-17, 32, 180, 182) for alerting personnel that a patient should be ventilated manually, that a patient is disconnected from the instrument, that control settings exceed specifications for the instrument, that undesired low gas pressure exists and that actual inspiration to expiration is less than that of the control setting. Flow and tidal volume limiting apparatus (72, 129) is provided, together with sigh circuitry (126) and devices (105, 104) for correcting for altitude and gas parameters.
(FR)Un ventilateur d"anesthesie (10) commande le debit d"air et/ou d"oxygene par l"intermediaire d"une pluralite de soupapes binaires a contrepoids (34-38) d"une source regulatrice de fluide (27) a un ensemble a soufflet (14). Les commandes directement reglees du volume par minute, de la frequence du souffle et du rapport inspiration-expiration (11, 12, 13) actionnent le circuit electronique (23) qui ajuste le debit, le volume de respiration et le nombre d"inspirations et d"expirations. Le circuit (23) comprend des dispositifs de detection d"alarme (15-17, 32, 180, 182) pour alerter le personnel pour l"avertir qu"un patient doit etre ventile manuellement qu"un patient est debranche de l"instrument que les reglages de commande depassent les caracteristiques de l"instrument qu"une basse pression de gaz indesirable existe et que le rapport reel inspiration/expiration est inferieur a celui du reglage de commande. Un appareil de limitation du debit et du volume de respiration (72, 129) est prevu, ainsi qu"un circuit de soupir (126) et des dispositifs (105, 104) pour corriger les parametres d"altitude et de gaz.
