Volume limiting ventilator |
| abstract |
A volume limiting ventilator having a sequencing servo for switching from an inhalation phase to an exhalation phase in its operative cycle. A bellows mounted in a container is provided for receiving gas from a source of gas under pressure. A master venturi is in communication with the interior of the bellows and the exterior of the bellows. A large air breathing tube forming a part of a breathing circuit connects the interior of the bellows to a patient adapter. A master flow cartridge controlled by the sequencing servosupplies source gas to the master venturi. A transfer valve assembly is provided for determining whether the gas flows straight through to the breathing circuit or alternatively is supplied to the container carrying the bellows to raise the bellows. The transfer valve assembly controls the transfer of gas in the container from the exterior of the bellows to the interior of the bellows. A volume stabilizer is provided for stabilizing the volumes between the interior of the bellows and the exterior of the bellows at the termination of the inspiratory phase. An expiratory nebulization cartridge is provided for supplying expiratory nebulization. |
