摘要
目的:解决医院医护人员在为患者静脉输液治疗时输液速度快慢难于掌握的问题。方法:通过液滴采样模块获得液滴脉冲信号,将获得的脉冲信号进行放大、整形并排除每个液滴上下界面产生的错误信号,输出标准的可触发信号,再经单片机处理电路,获得实时的分钟液滴速度和平均分钟液滴速度。结果:抗干扰手持式输液液滴计数器能够以显示屏显示实时分钟液滴数和平均分钟液滴数。结论:抗干扰手持式输液液滴计数器结构简单,使用方便,已投入临床使用。
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.
