Abstract
Varicose veins of lower extremity can be treated effectively with varicose vein therapy apparatus. In order to ensure its therapy effect, it is necessary to test the air tightness of pneumatic circuit and other related performance parameters. The traditional manual testing method has some problems, such as large error, low efficiency and so on. This paper developed a multifunctional testing system based on LabVIEW software to overcome these shortcomings. The system is a combination of software and hardware, which can realise key components calibration, pneumatic circuit air tightness testing, gasbag pressure-resistance performance testing, pressure sensor performance testing and air pump performance testing. The multifunctional testing system realises the goal of automated human-computer interaction testing, which has a bright future in the aspects of application prospect.
