前言:
中国人口众多,医疗资源匮乏,人们就医难从建国开始就一直存在,如何使医疗资源能惠及大众,让老百姓们享受医疗资源更加的公平,也是政府管理者一直在思考解决的问题。解决公平问题,一是要靠制度,二是要靠技术。目前在医疗领域普遍应用的信息化技术手段,就可有效的辅助解决医疗资源有效利用的问题。比如目前医院一号难求的局面,如何更加公平的解决,从而遏制黄牛倒号党的产生,并且更加有利于群众挂号治病。在线预约挂号系统可以在这方面起到非常积极的作用,通过患者注册账号,一个身份证只能挂一个号,人证对照,接诊时必须是本人就诊才可以实现看病就医,一是方便群众在家就可以远程挂号预约时间,二是也可有效的解决就医公平问题。
一,项目简介
本项目基本UNI-APP前端框架开发,后台基于Springboot+Vue开发实现,完成了一个在线预约挂号系统,系统的使用角色有三个:管理员、患者、医生。
患者的主要功能:
- 注册登陆
- 查看资讯信息:对信息进行点赞、收藏、评论
- 查看医院的挂号大厅:可以对医生进行点赞评论,在线预约挂号
- 个人中心:管理个人信息,查看预约信息列表,取消预约信息,修改预约信息等操作
医生的主要功能:
- 登陆
- 查看资讯信息:对信息进行点赞、收藏、评论
- 查看医院的挂号大厅:可以对发布的挂号信息进行查看等
- 个人中心:管理个人信息,查看预约信息列表等操作
管理员的主要功能:
- 登陆系统
- 轮播图管理
- 公告信息管理
- 用户管理:管理员管理、普通用户管理、医生用户
- 内容管理:资讯信息管理、资读分类管理
- 挂号大厅:发布挂号信息
- 挂号信息查看及修改
- 查看己取消的挂号信息
二,环境介绍
语言环境:Java: jdk1.8
数据库:Mysql: mysql5.7
应用服务器:Tomcat: tomcat8.5.31
开发工具:IDEA、HbuilderX、微信开发者工具
开发技术:后台开发Springboot+Mybatis
前台开发:UNI-APP和微信小程序

五,项目总结
现在人们的生活节奏随着生活压力的增大越来越高,人们变得十分焦虑,不再有耐心等待。而计算机信息化技术有效应用,有效的解决人们对时空效率的要求,它的应用不断地渗入到各个邻域,比如像在医疗领域、教育方面等,信息化技术的使用确实给我们的生活带来很大的改变。比如就医疗领域方面来讲,以前我们很多医院就医生挂号大多都采用的是人工排队挂号的方式,这种方式不难浪费了患者的时间,也降低了就诊的效率,本就资源匮乏的医疗领域,则变的更加紧张,这不仅造成医院拥挤秩序混乱,更是拉动人力物力成本高。在线预约挂号系统则可以有效的解决这一问题,患者只需在家通过电脑访问挂号系统网站即可实现在线挂号,即方便患者,又节省医院资源,提高就诊效率,增加医院收入。
