A ventilator is a medical device used to provide artificial respiration. It is commonly used to treat respiratory diseases such as severe respiratory distress syndrome (ARDS), sleep apnea syndrome (OSAS), pneumonia, acute lung injury, etc. Ventilators improve breathing by injecting oxygen or a mixture of gases into the patient's lung spaces. Ventilators can be
With the rapid development of the current industry, the internal structure of various mechanical equipment is becoming more and more sophisticated and complex, which brings difficulties to industrial inspection. In order to detect problems in equipment in time and prevent problems before they happen, non-destructive testing technology is playing an increasingly important role in
