Abstract

The present invention provides a computer controlled ventilator device meant for delivering compressed air and/or oxygen into a patient's lungs. The said device is comprised of: (a) an electrical power supply (21, 22); (b) a main electronic board containing a double CPU unit (19), connected to the said power supply (21, 22) to the compressor (7) and to all the electronically controlled units to all the sensors and to the control display and alarm panel (20); (c) a control display and alarm panel (20) connected to the said main electronic board (18); (d) an air compressor (7) having a pulse-activated DC motor (7a) connected to the main electronic hoard (18); (e) a first means for supplying air or air/O 2 mixture to the said compressor (7); (f) a second means for selecting the operation mode, connected to the CPU (19) and to the compressor (7); (g) an inspiratory flow sensor (9) and a pressure sensor (16) connected to the compressor (7) and to the CPU (19); (h) a patient circuit hose (11) connected to the said inspiratory flow sensor (9); (i) a simple passive patient valve or three-way solenoid operated valve (12) connected to the patient circuit (11) and to a means (17) for providing air to the patient's lungs; (j) a mechanical back-up relief valve (10), connected to the inspiratory flow sensor (9) or to the patient valve (12) to protect the patient from a possible overpressure; (k) a third means (17) for providing air to the patient's lungs. The present invention provides a ventilator that has two operation modes: (a) Preset Mode; (b) User-set Mode. In the preset mode a patient's weight adjustement knob (6, 25) is rotated to provide an input to the CPU (19). The CPU (19) uses the weight data to select a preprogrammed ventilation procedure and the desired ventilation parameters. The CPU (19) uses also the input to the different sensors for feedback control. In the user-set mode, the operator selects the ventilation parameters such as Rate, Tidal Volume and Relief Pressure, and the ventilation method such as SIMV, IPPV, and Pressure support.
