Embodiment Construction

[0013] figure 1 is a schematic diagram depicting an embodiment of a system 10 for providing mechanical ventilatory support to a patient 12 .

[0014] System 10 includes breathing circuit 14 . The breathing circuit 14 directs medical gas towards the patient 12 through an inspiratory segment 16 and directs exhaled gases away from the patient through an exhalation segment 18 . Y-connector 20 connects inspiratory segment 16 and expiratory segment 18 to patient connection 22 , which facilitates pneumatic connection of system 10 to patient 12 . It is understood that there are a wide variety of patient connections 22 that may be used with embodiments of the system 10 . These patient connections 22 include, but are not limited to, an endotracheal tube, a ventilation mask, and a laryngeal mask.

[0015] The breathing circuit 14 is pneumatically connected to a bellows 24 . Bellows 24 is operated by a mechanical ventilator 26 that provides a supply of drive gas 28 to bellows 24 to cr...

Abstract

The present invention relates to a system and a method for providing mechanical ventilation support to a patient. The system for providing mechanical ventilation support to a patient and includes a mechanical ventilator (26). A breathing circuit (14) is pneumatically connected between the mechanical ventilator (26) and a patient connection (22). An inspiratory check valve (30) is disposed within an inspiratory limb (16) of the breathing circuit (14). A fresh gas manifold (38) provides fresh gas to the breathing circuit (14) for delivery to the patient. A fresh gas valve (52) is disposed between the fresh gas manifold (38) and the breathing circuit (14). The fresh gas valve (52) is operable between a first position which directs fresh gas upstream of the inspiratory check valve (30) and a second position that directs fresh gas downstream of the inspiratory check valve (30). A digital signal processor (44) operates the fresh gas valve (52) selectively between the first position and the second position. A method of ventilating a patient includes introducing a flow of fresh gas into an inspiratory limb (16) of the breathing circuit (14). A ventilatory support value is sensed with at least one sensor (62, 64) disposed within the breathing circuit (14). An operational condition of the breathing circuit (14) is identified with a digital signal processor (44). A fresh gas valve (52) is operated with the digital processor (44) between a first position that directs fresh gas to the inspiratory limb (16) upstream from the inspiratory check valve (30) and a second position that directs the fresh gas downstream from the inspiratory check valve (30).

Description

technical field [0001] The present disclosure relates to the field of mechanical ventilation for patients undergoing general anesthesia. More specifically, the present disclosure relates to systems and methods for controlling the introduction of fresh gas into a breathing circuit. Background technique [0002] Mechanical ventilatory support is a common treatment technique offered to patients who are too weak due to sedation or muscle paralysis to complete a breathing cycle without external assistance. Provide artificial ventilation to patients who experience complete lung failure and are unable to initiate breathing cycles under their own power. Provide ventilatory assistance to patients who are able to initiate spontaneous breathing but benefit from external control of volume duration and inhaled concentrations provided with ventilatory assistance. [0003] Previous mechanical ventilation systems kept exhaled gases away from the patient and included only fresh gases with ...
