Description
技术领域technical field
本发明涉及医疗废物的管理和处置技术领域,具体地说,涉及一种医疗卫生机构医疗废物的综合处理方法及系统。The invention relates to the technical field of management and disposal of medical waste, in particular to a method and system for comprehensive treatment of medical waste in medical and health institutions.
背景技术Background technique
医疗废物,是指医疗卫生机构在医疗、预防、保健以及其他相关活动中产生的具有直接或者间接感染性、毒性以及其他危害性的废物。医疗卫生机构和医疗废物集中处置单位须遵守《医疗废物管理条例》,开展医疗废物的收集、运送、贮存、处置以及监督管理等活动。Medical wastes refer to wastes with direct or indirect infectivity, toxicity and other hazards generated by medical and health institutions in medical treatment, prevention, health care and other related activities. Medical and health institutions and centralized medical waste disposal units must comply with the "Medical Waste Management Regulations", and carry out activities such as collection, transportation, storage, disposal, supervision and management of medical waste.
按照规定,城市的医疗卫生机构应当根据就近集中处置的原则,及时将医疗废物交由医疗废物集中处置单位处置。医疗废物集中处置单位处置医疗废物,按照国家有关规定向医疗卫生机构收取医疗废物处置费用,医疗卫生机构按照规定支付的医疗废物处置费用。According to the regulations, urban medical and health institutions should timely hand over medical waste to the centralized medical waste disposal unit for disposal according to the principle of nearby centralized disposal. The medical waste centralized disposal unit disposes of medical waste, and collects medical waste disposal fees from medical and health institutions in accordance with relevant state regulations, and medical and health institutions pay medical waste disposal fees in accordance with regulations.
就上海来说,目前上海有5800多家医疗卫生机构。2018年,上海市物价局、上海市环境保护局、上海市卫生和计划生育委员会联合发布了《关于完善医疗废物处置收费机制的通知》(以下简称《通知》),给出了两种医疗废物处置费计费方式:(一)有床位的医疗卫生机构及相关单位可自主选择按住院病人实际占用床日数或按医疗废物的重量支付医疗废物处置费。(二)无住院病人的医疗卫生机构及相关单位月平均产生医疗废物100公斤以下的,按定额支付医疗废物处置费;月平均产生医疗废物100公斤及以上的,按医疗废物的重量支付医疗废物处置费。2018年度医疗废物处置费收费标准如下:As far as Shanghai is concerned, there are currently more than 5,800 medical and health institutions in Shanghai. In 2018, the Shanghai Price Bureau, the Shanghai Environmental Protection Bureau, and the Shanghai Municipal Health and Family Planning Commission jointly issued the "Notice on Improving the Charging Mechanism for Medical Waste Disposal" (hereinafter referred to as the "Notice"), giving two types of medical waste. Disposal fee billing method: (1) Medical and health institutions and related units with beds can choose to pay the medical waste disposal fee according to the actual number of bed days occupied by the inpatients or the weight of the medical waste. (2) If the medical and health institutions and related units without inpatients produce an average of less than 100 kilograms of medical waste per month, the medical waste disposal fee shall be paid according to the fixed amount; if the average monthly amount of medical waste is 100 kilograms and above, the medical waste shall be paid according to the weight of the medical waste. disposal fee. The charging standards for medical waste disposal fees in 2018 are as follows:
表1:2018年度医疗废物处置费收费标准Table 1: 2018 medical waste disposal fee charging standard
该收费标准的价格相比于之前有所提高,增加了医疗卫生机构在医疗废物处置方面的成本。对于选择按重量计费的医疗卫生机构,则十分有必要研究科学合理的医疗废物管理、处置的新思路,以降低成本。The price of this fee has increased compared to the previous one, increasing the cost of medical waste disposal for medical and health institutions. For medical and health institutions that choose to charge by weight, it is very necessary to study new ideas for scientific and reasonable medical waste management and disposal to reduce costs.
目前虽有较多文献报道了医疗废物收集、运送、贮存、处置以及监督管理相关的技术,但基本都是涉及其中的一个环节,且较少考虑医疗卫生机构处理医疗废物方面的经济支出。例如,专利文献CN108960358A,公开日2018.12.07,公开了一种医疗垃圾称重回收方法及系统,方法包括获取医院科室终端发送的医废收集请求;发送医废收集请求至收集人员的第一智能移动终端;获取第一智能移动终端发送的医废信息;将医废信息存储至系统服务器数据库;接医废负责人的医废确认信息;发送医废信息至产废单位暂存间负责人的第二智能移动终端;获取复核入库信息;发送医废信息至处置单位接运人员的第三智能移动终端;获取第三智能移动终端扫码装车信息;将扫码装车信息发送至第二智能移动终端;获取第二智能移动终端的复核出库确认信息;获取处置单位负责人的第四智能移动终端的扫码出库信息;发送医废处置信息至医院科室终端。该技术方案涉及医疗废物的监督管理,旨在实现对医疗废物的全过程可追溯监管。专利文献CN108332214A,公开日2018.07.27,公开了一种医疗废弃物处理方法,所述处理方法采用医疗废弃物处理装置,所述医疗废弃物处理装置包括焚烧炉、混合管、一级吸附室、二级吸附室、临界反应腔和分离腔。该技术方案涉及医疗废物的处置,旨在通过特定装置的设置搭配具体的医疗废弃物处理方法,使得现有已知的临界水处理医疗焚烧飞灰的处理方法能够实现烟气和水都重新进行处理而达到完全的无害化处理,从而在处理医疗废弃物的过程中不对大气和水造成二次污染。专利文献CN107777173A,公开日2018.03.09,公开了一种用于医疗废物的分类存放系统,包括微控制器、语音识别模块、多个电机和多个并排存放的垃圾桶,所述微控制器和语音识别模块安装在一个垃圾桶的侧壁上,每个所述垃圾桶均包括底座、外壳体、上盖和传动机构,所述底座设于外壳体底部,所述上盖位于外壳体上方且所述上盖一侧与外壳体铰连接,所述传动机构一端铰接于上盖,另一端与安装在底座内的电机连接,所述微控制器输入端连接语音识别模块,输出端连接多个电机。该技术方案涉及医疗废物的院内贮存,旨在采用人工智能控制垃圾桶的开启和闭合,满足不同医疗废物的单独存放,避免人体接触,提高安全性。At present, although there are many literatures reporting technologies related to the collection, transportation, storage, disposal, and supervision and management of medical waste, they are basically involved in one of the links, and less consideration is given to the economic expenditure of medical and health institutions in dealing with medical waste.
