目的 为了提高医疗设备管理软件的使用率，真正实现无死角实时、便捷操作的目的，在开发软件时必须要求软件 在断网离线后对数据的获取、展示、保存有一定的处理能力。方法 通过分析Android系统中的几种数据存储方式，包括 SQLite、Web缓存等，结合目前医疗设备管理所需数据的特征，使用合适的处理方法，配合基于Android开发的APP进行离 线测试。结果 针对不同的数据，APP能够完成本地数据库、Web缓存数据的基本处理，操作时基本流畅，没有明显卡顿现 象。结论 数据离线缓存使得软件在无线信号丢失情况下仍能发挥重要作用，提高了软件的可用性。

Objective In order to improve the utilization rate of medical equipment management software and truly realize the purpose of real-time and convenient operation without blind angle, it is necessary to require the software to have certain processing ability to acquire, display and save data after being offline when developing software. Methods Several data storage methods in the Android system including Sqlite and Web cache, and so on were analyzed. Combining with the characteristics of data needed for medical device management at present, appropriate processing methods were used, and an android-based APP was developed for offline testing. Results For different data, the APP could complete the basic processing of local database and Web cache data, and the operation was basically smooth without obvious lag. Conclusion The off-line data cache enables the software to continue to work smoothly even if the wireless signal is lost, which improves the usability of the software.
