Description

一种一次性采血器针头终末消毒方法及终末消毒系统 技术领域
本发明属于医疗技术领域,特别涉及一种一次性采血器针头终末消毒方法及终末消毒系统。
背景技术
现有一次性采血器主要用于:(1)临床少量采血检验;(2)糖尿病患者的血糖监测;(3)一些传染性疾病的快速筛查,如艾滋病、梅毒、乙肝等病。采血器使用后,由于针头仍残留血液,必须在专门的卫生机构进行终末消毒处理。但是对于后两种情况,人们可以自行购置一次性采血针头,并在医疗场所以外的地方使用,而往往并未将其送回专门的医疗机构进行终末消毒处理,从而有可能导致带有传染性病毒血液的一次性采血针头滞留在人们的生活环境中。
在当前社会计算、大数据应用等新一代互联网应用背景下,网络应用更加广泛,信息的产生和变化更加快速。例如,日常生活中人们使用各种商务系统的频率更加频繁,系统中的用户数量以及商品数量都在不断增加,因而引起了系统中数据量的急剧增加和变化,这给推荐技术的研究和应用带来了所谓的可扩展性问题。为帮助用户有效解决他们在网络应用中所面临的信息超载问题,迫切需要一种能够在这种数据规模不断扩大、信息的增加和变化日益频繁的环境下,能够对用户的请求作出及时、快速和准确响应的鲁棒性推荐技术。
综上所述,现有技术存在的问题是:
(1)现有技术中,使用者在没有严格按照产品使用要求收集使用后的针头到卫生机构进行集中消毒处理时,增大了带有传染性病毒的针头滞留于社会环境中的危险。如果能将使用后的采血针头自行进行终末的消毒处理,则人们在非医疗场所使用后则可以作为生活垃圾丢弃,则极大方便了人们的使用,将会减少传染性病毒可能残存针对而对社会环境带来的风险。
(2)现有的血量测量模块仅凭人工进行控制,不能实现自动化控制,控制精度低。
(3)在网络应用日益广泛深入的背景下,面对数据稀疏性、大数据处理与增量计算等问题,如何在采血推荐的准确性和时间效率、空间效率以及算法的可扩展性等方面进行权衡,研究开发出在时间效率、空间效率、准确性和可扩展性等方面综合性能良好的推荐技术,它直接关系到推荐技术的实际评价应用价值
发明内容
