Abstract:
A tracheal gas insufflation system comprising:an insufflation catheter having a proximal end portion located generally outside a patient and a distal end portion adapted to be located in an airway of a patient for providing a flow of insufflation gas to such a patient; anda vent assembly disposed at the distal end portion of the insufflation catheter, the vent assembly including:a first port that directs a first portion of the flow of insufflation gas from the insufflation catheter generally in a first direction into such a patient's respiratory system, anda second port that directs a second portion of the flow of insufflation gas generally in a second direction out of such a patient's respiratory system, with a vector force being associated with discharge of the flow of insufflation gas from the first and the second ports, and wherein the vent assembly is configured and arranged such that a net of all vector force components in the first direction and in the second direction resulting from discharge of the flow of insufflation gas into such a patient's airway by the vent assembly is substantially zero.
