Abstract:
【Objective】 To establish a method for batch weighing blood components intelligently and accurately. 【Methods】 Virus inactivated plasma was used as weighing samples. The traditional electric scale and cryoprecipitation preparation instrument were used to weigh plasma with five specifications. The consistency of the weighing results by the two methods was statistically analyzed. Two groups of virus inactivated plasma with basically the same number of bags were randomly selected, and weighted by the same group of staff using these two equipment, the time for weighing and the time from weighing to registering were calculated statistically. 【Results】 227 bags of plasma were weighed in batches by the two methods, and statistical analysis showed no significant difference in standardized blood volume. There was no significant difference in plasma weighing time (71/68)by the same staff, weighing basically the same number of bags. However, the time difference from weighing to registering was statistically significant, as the new method was 2.65 s shorter than the traditional one (P<0.05). 【Conclusion】 The new method is accurate for batch weighing, and can realize the informatization and intellectualization of blood weighting. The time consumed from weighing to registration was improved by the new method, but not in time for weighing.
