Tracheal gas insufflation delivery system for respiration equipment

摘要

A tracheal gas insufflation delivery system for use with a ventilator breathing system including a ventilator and a breathing circuit. The delivery system includes a flow generator connected to the inspiratory limb of the breathing circuit through an inlet line. The flow generator is operated to draw off a supply of gas to be used during tracheal gas insulation through the inlet line. The flow generator is connected by a delivery line to the patient limb of the breathing circuit, preferably, near the distal end of an endotracheal tube used in the patient limb. The gas supplied by the delivery line reduces the volume of previously exhaled gases subsequently breathed by the patient increasing the physiological efficiency of patient ventilation and allowing a reduction in ventilatory pressures. The tracheal gas insufflation delivery system may include an intermediate cylinder that can be filled by the flow generator so that the tracheal gas insufflation delivery system can deliver a greater supply of gas.
