背景技术
医疗指疾病的治疗，对于现代医疗系统来说，西医占用很大的比重，在西医中，输液（俗称点滴）在西医中占有很大的比重， 在输液中，点滴的数量是输液中的重要标准。现有技术的医院常用输液滴速是用每分钟滴数来表示，而滴数是根据体积结合每毫升对应的滴数以及点滴系数计算的。测量体积和滴数的光学方法精度很低，在实际临床中难以使用。

101、获取当前时刻点的输液瓶重量W(n)和上一时刻输液瓶重量W(n—1)；
102、计算差值= W(n—1)—W(n)；
103、如差值为负数，则对W(n)进行校正；
104、如差值为正值，则V（n）=K(n)*r*60;
其中，r为体积重量系数，V（n）为滴速；K(n)= sum(F1-F)/sum(T)；
其中，F1=W(n—2)；F= [w(n-2), w(n-1), w(n), w(n+1), w(n+2)] – w(n+2) ；
T = [T1=0, T2, T3,T4,T5] = [t(n-2), t(n-1), t(n), t(n+1), t(n+2)] – t(n-2)。
可选的，所述对W(n)进行校正具体为：
w(n) = w(n-1) – k(n-1)*(t(n) – t(n-1))。
另一方面，提供一种输液校正系统，所述系统包括：
获取单元，用于获取当前时刻点的输液瓶重量W(n)和上一时刻输液瓶重量W(n—1)；
计算单元，用于计算差值= W(n—1)—W(n)；
校正单元，用于如差值为负数，则对W(n)进行校正；
计算单元，还用于如差值为正值，则V（n）=K(n)*r*60;
其中，r为体积重量系数，V（n）为滴速；K(n)= sum(F1-F)/sum(T)；
其中，F1=W(n—2)；F= [w(n-2), w(n-1), w(n), w(n+1), w(n+2)] – w(n+2)；
T = [T1=0, T2, T3,T4,T5] = [t(n-2), t(n-1), t(n), t(n+1), t(n+2)] – t(n-2)。
