Python项目源码63：病历管理系统1.0（tkinter+sqlite3+matplotlib）

1.病历管理系统包含以下主要功能：

核心功能：病历信息录入（患者姓名、年龄、性别、诊断结果、主治医生），自动记录就诊时间，病历信息展示（使用Treeview表格），病历信息查询（按姓名搜索），数据sqlite3存储。
主要组件：输入表单：包含患者基本信息输入字段，功能按钮：添加、查询、保存、加载、清空，病历列表：以表格形式展示所有病历记录，双击支持：双击记录可自动填充到输入框。
数据库存储：使用SQLite3替代JSON文件存储，自动创建数据库表结构，使用参数化查询防止SQL注入。

2.使用说明：运行程序后会生成medical_records.db文件用于存储数据，输入患者信息后点击"添加病历"按钮保存，输入姓名等条件进行高级搜索，双击表格记录可将数据填充到输入框。

高级查询

数据可视化
