초록 ▼

The conditioned air from a ventilator enters one chamber in a manifold, which chamber has a connection to an inspiratory conduit through which the conditioned air is conducted to the patient. The expiratory conduit from the patient communicates in the manifold with a second chamber, positioned below the first chamber. A wall in the manifold at the lowermost part of the first chamber defines an orifice providing fluid communication between the two chambers. At the lower part of the second chamber is the expiratory valve which is pulsed by the ventilator. Adjacent the patient is a slanted “Y”and elbow which provide communication between the inspiratory conduit, the expiratory conduit, and the patient\s single endotracheal or tracheostomy tube. Various ports are provided in the “Y”and elbow and are closed by caps. These ports provide connections suitable for various needs such as temperature measurement, ventilator temperature controller probe, etc. In one embodiment the connections at the elbow provide freedom of rotational movement in two planes, which planes are at approximately right angles to each other. Various other features are incorporated to facilitate use of the ventilation apparatus to meet diverse requirements.

A condensate removal system for use with a ventilation circuit extending between a patient and a ventilator having means for conditioning the air, wherein said circuit includes a manifold having an interior chamber and including internal wall means dividing the interior chamber of the manifold into an inhalation chamber having a lowermost portion and an exhalation chamber having a lowermost portion with the lowermost portion of the inhalation chamber being positioned above the lowermost portion of the exhalation chamber, said manifold having a lowermost portion communicating with the lowermost portion of said exhalation chamber and an exhaust conduit connection in that lowermost portion, an air-supply conduit having one end connected to said inhalation chamber and the other end adapted to be connected to the ventilator, a patient inspiratory conduit connected to the manifold and communicating with the inhalation chamber above the lowermost portion thereof, a patient expiratory conduit connected to the manifold and communicating with said exhalation chamber above the lowermost portion thereof, a discharge conduit connected to the exhaust conduit connection of the manifold, conduit means adjacent the patient and to which the inspiratory and expiratory conduits are connected with the conduit means providing fluid communication between the inspiratory and expiratory conduits, and valve means mounted in the manifold for controlling the flow of fluid from the expiratory chamber to the discharge conduit, said valve means adapted to be connected to the ventilator for timing the opening and closing of the valve means in accordance with selected modes of patient ventilation, said condensate removal system being characterized by: said valve means being positioned in the manifold between the lowermost portion of the exhalation chamber and said lowermost portion of the manifold to control the flow of fluid therebetween, said manifold having air-supply conduit and inspiratory conduit connections to which said air-supply conduit and inspiratory conduit are connected and communicate with said inhalation chamber and an expiratory conduit connection to which said expiratory conduit is connected and communicates with said exhalation chamber, and said wall means including a lower wall portion defining an orifice forming a fluid communication between the inhalation and exhalation chambers; whereby liquid accumulating in the exhalation conduit will drain into the exhalation chamber and liquid accumulating in the inhalation chamber will drain through the orifice into the exhalation chamber and thence pass through the valve means, when open, to the exhaust conduit connection, and said orifice presents a substantial resistance to the flow of air between the two chambers as compared to the resistance to the flow of air between the two chambers that exists through the inspiratory and expiratory conduits and their fluid communication at the conduit means to the end that the orifice is virtually closed to the passage of air during normal operation of the ventilation circuit.
