摘要:为给紧急需要某种药物且意识清醒的用户快速提供药品,研究基于地理位置的药品求助和响应救助具有重要意义。在分析了用户急需某种药品但是无法获得时的需求,设计了基于用户地理位置(LBS)的“急速药递”小程序管理系统,对系统的紧急求助、消息推送、地图显示和基本信息填报等功能模块进行分析与设计,主要运用位置标记的方式展示求助信息、以消息推送的形式通知附近的志愿者或医药机构、地图显示药品求助信息、附近多位商家或志愿者响应求助并快速将药品送达,实现基于LBS的药品需求信息服务。系统采用云开发模式开发,描述了系统实现的关键技术,具有一定的实用价值。

Abstract: In order to provide drugs to the conscious and urgent users, it is of great significance to study the drug help seeking and response assistance based on geographical location. Based on the analysis of the user's need for a certain drug but unable to obtain it, a "rapid drug delivery" wechat applet management system based on LBS was designed. The function modules of the system, such as emergency help, map display, message push and basic information filling, were analyzed and designed. The help information was displayed in the way of location mark, and the volunteers nearby were informed in the form of message push Or medical institutions, map display drug help information, nearby businesses or volunteers respond to help and quickly deliver drugs, so as to realize drug demand information service based on user geographic location (LBS). The key technologies of the system implementation are described, it has a certain practical value.

1 背景

冠心病引发的心脏骤停,每过1分钟,死亡率上升7-10%。冠心病急性发作后的生存率,在全球大约3%,中国只有1%。根据国务院出台的标准,接到报警后,救护车应在15分钟内到达患者驻地,但在实际情况中,不仅由于医疗设施的不足,恶劣的交通状况也同样使得救护车难以及时到达患者身边,有时因为患者独自发病未能报警或未随身携带急救药品甚至未被发现而贻误急救。用户明确自己需要哪种药,但是因为某种原因(发病时忘了带药等)而无法获得,如何为用户急速“药”递?构建便捷的院外救助信息系统,实现求救信息畅通、救助及时具有重要的意义。……
