Ultrasonic Hand-held Spirometer Computer Based

Wuhan Cubic Optoelectronics Co., Ltd

no maintenance, light-weight, easy handling

It adopts ultrasonic technology by ultrasonic gas flow sensor to measure body’s respiratory function and inspiratory function, to convert the patient breathing signal into electrical signal which is sent to corresponding signal processing circuit, to display real-time respiratory flow curve and then to calculate a variety of physiological and spirometric parameters. It can be used to monitor static vital capacity, forced vital capacity and maximum voluntary ventilation rate.

The software can automatically do BTPS correction and evaluate pulmonary function.
