This invention relates to a jet ventilator system to ventilate patients during surgical procedures. The jet ventilator system of the invention comprises a driving gas source (10), a flow regulator (18) by means of which the driving gas flow may be regulated and a trigger (22) to control the flow, the trigger (22) being integral with the flow regulator (18). The integration of the flow regulator (18) with the trigger (22) enables the integration of a multiplicity of ventilator functions into a single, integrated ventilator system. To this end, the ventilator system may include an eductor (30) adapted to educt fluid into the driving gas stream during use by mixing the incoming fluid with the driving gas in the eductor (30). Preferably the system includes dedicated air and fluid eductors. The fluid eductor can be connected to a surgical suction device at its inlet end and, at its outlet end, to a waste disposal facility. The jet ventilator system of the invention includes a control system with time switched regulators constituted by an inspiratory regulator, an expiratory regulator and a manual override switch that is integrated with the flow regulator (18). |
