Flow testing simulator

for respiratory ventilators

The breathing simulator is used with the Inhalant drug tester. It provides a simulated respiratory function for inhalant aerosol, spray, powder, and liquid preparation. Product Features 1. Data sampling mode: Control cycle 250us, the transmission rate of up to 1000 data points per second 2. Piston barrel: the effective capacity is 1000ml; 3. Special software: you can set and save breathing parameters; you can also choose breathing curve, you can choose sine, triangular wave, square wave breathing mode, simulate normal breathing, acute movement, sleep 3 different breathing states; 4. Tidal volume: 20 ~ 1000ml (can be set), simulate adult, child, infant, and newborn respiratory tidal volume; 5. Respiratory rate: 0 ~ 60 cycles/min (configurable); 6. Breathing ratio: Within 1:9 can be arbitrarily set suction and breathing ratio; 7. Control mode: control cycle 250us, FPGA accurate latch pulse count, PID + speed feedforward + acceleration feedforward, positive and negative limit, origin signal, driver alarm, driver reset, in place signal (optocoupler isolation); 8. Control instruction: can automatically identify and suppress mechanical vibration. Position pulse input frequency up to 4MHz, support pulse + direction, orthogonal pulse, double pulse, and other position command modes; 9. Dead volume of filter paper cover: not more than 10% of the adult tidal volume of the respiratory simulator; 10. Pressure test: range 0 ~ 2KPa, accuracy ±0.01KPa; 11. Flow test: range 0 ~ 10L/min, accuracy ±0.02L/min; 12. Industrial 17-inch touch computer, supporting English and Chinese interface switching; 13. Intelligent control system
