초록 ▼

A ventilator implemented completely with fluidic devices provides independent control of inhalation time, exhalation time and breathing gas flow rate. The basic fluidic system comprises a low frequency oscillator which in the form of a flip flop is controlled in its two stable states by means of independently controlled time delay relays. The output of the flip flop is amplified by a digital amplifier and operates an on-off valve which is used to direct breathing gas from the source to the patient. Independent control of the flow rate of the breathing gas is by means of a needle valve. With this basic fluidic system, there are seven other features of the apparatus. One is a maximum pressure control which on inhalation is responsive to the patient\s breathing air pressure. The second feature is a sensitivity control, which during exhalation is responsive to the patient inspiratory effort. The third feature is a positive end exhalation pressure control. The fourth is an intermittent mandatory ventilation control which permits breathing rates as low as one breath per minute. The fifth feature is a manual control which allows the termination of the exhalation phase and initiation of the inhalation phase manually. The sixth feature is a sensor which is responsive to the breathing gas pressure at the patient. If the apparatus becomes detached from the patient, pressure cycling is modified and an alarm system sensitive to this pressure is activated. The seventh feature is a safety valve which allows the patient to breathe atmospheric air when the supply pressure of the source gas fails.

A positive pressure ventilator comprising: a. a source of breathing gas; b. a normally closed first valve means (40) for directing the breathing gas from said source to the patient; c. A first bistable means (32) for controlling said first valve means, said first bistable means having a first set of opposed control inputs; d. a first time delay means (28), and a second time delay means (30), each independently adjustable in time delay; e. means responsive to said first time delay means to operate one of said first inputs of said first bistable means to open said first valve means, and to trip said second time delay means, and to initiate the inhalation action; and f. means responsive to the operation of said second time delay means to operate a second one of said first inputs of said first bistable means to close said first valve means and to trip said first time delay means and initiate the exhalation action; and including g. between said source of breathing gas and said first valve means a pressure controller (38) for maintaining a constant supply pressure to said valve; and h. between said first valve means and said patient a flow rate control valve (R5); whereby a selected constant value of flow rate of gas is supplied to said patient when said first valve means is open; and including non-rebreathing valve means having an open and a closed position, including i. spring means to open said non-rebreathing valve in the absence of operating pressure, said non-rebreathing valve connected to the supply line of breathing gas for the patient and including j. fluidic OR gate means for applying pressure to close said non-rebreathing valve during the inhalation phase, and to open said non-rebreathing valve during the exhalation phase.
