Abstract:
Objective To resolve the difficulty in controlling the transfusion speed by medical personnel.Methods By using liquid drop sampling module,pulsing signals of liquid drop were obtained,and then they were enlarged,shaped and the wrong signals from the top and bottom surface of every drop were excluded before the standard triggered signals were sent out to SCM processing circuit,from which the real-time liquid drop speed and the average drop speed in every minute were obtained.Results Anti-interference and portable transfusion-drop counter could show the real-time liquid drop value and the average liquid drop value in every minute.Conclusion Anti-interference and portable transfusion-drop counter is convenient with simple structure and has been used in clinic.
