互联网医院系统源码

一、智慧互联网医院系统的架构设计

-挂号

-问诊、

-病历

-管理

-药品

-配送

……

二、源码解析

以简单的在线问诊模块为例，进行源码解析。

数据库设计

首先，设计数据库表结构。在线问诊模块涉及的主要表有用户表（User）、医生表（Doctor）、问诊记录表（Consultation）。


-- 用户表

CREATE TABLE User (

    id INT PRIMARY KEY AUTO_INCREMENT,

    username VARCHAR(50) NOT NULL,

    password VARCHAR(50) NOT NULL,

    role ENUM('patient', 'doctor') NOT NULL

);

 

-- 医生表

CREATE TABLE Doctor (

    id INT PRIMARY KEY AUTO_INCREMENT,

    user_id INT,

    specialty VARCHAR(100),

    FOREIGN KEY (user_id) REFERENCES User(id)

);

 

-- 问诊记录表

CREATE TABLE Consultation (

    id INT PRIMARY KEY AUTO_INCREMENT,

    patient_id INT,

    doctor_id INT,

    consultation_time DATETIME,

    description TEXT,

    FOREIGN KEY (patient_id) REFERENCES User(id),

    FOREIGN KEY (doctor_id) REFERENCES Doctor(id)

);

后端实现

后端使用Node.js和Express框架进行开发。


const express = require('express');

const app = express();

const bodyParser = require('body-parser');

const mysql = require('mysql');

 

app.use(bodyParser.json());

 

const db = mysql.createConnection({

    host: 'localhost',

    user: 'root',

    password: 'password',

    database: 'smart_hospital'

});

 

db.connect((err) => {

    if (err) throw err;

    console.log('Database connected!');

});

 

// 用户注册接口

app.post('/register', (req, res) => {

    let user = req.body;

    let sql = 'INSERT INTO User (username, password, role) VALUES (?, ?, ?)';

    db.query(sql, [user.username, user.password, user.role], (err, result) => {

        if (err) throw err;

        res.send('User registered!');

    });

});

 

// 在线问诊接口

app.post('/consult', (req, res) => {

    let consult = req.body;

    let sql = 'INSERT INTO Consultation (patient_id, doctor_id, consultation_time, description) VALUES (?, ?, ?, ?)';

    db.query(sql, [consult.patient_id, consult.doctor_id, consult.consultation_time, consult.description], (err, result) => {

        if (err) throw err;

        res.send('Consultation record created!');

    });

});

 

app.listen(3000, () => {

    console.log('Server started on port 3000');

});

前端实现

前端使用React框架。


import React, { useState } from 'react';

import axios from 'axios';

 

function App() {

    const [username, setUsername] = useState('');

    const [password, setPassword] = useState('');

    const [role, setRole] = useState('patient');

    const [description, setDescription] = useState('');

 

    const register = () => {

        axios.post('/register', { username, password, role })

            .then(response => {

                alert(response.data);

            });

    };

 

    const consult = () => {

        axios.post('/consult', { patient_id: 1, doctor_id: 1, consultation_time: new Date(), description })

            .then(response => {

                alert(response.data);

            });

    };

 

    return (

        <div>

            <h1>智慧互联网医院</h1>

            <div>

                <h2>用户注册</h2>

                <input type="text" value={username} onChange={e => setUsername(e.target.value)} placeholder="用户名" />

                <input type="password" value={password} onChange={e => setPassword(e.target.value)} placeholder="密码" />

                <select value={role} onChange={e => setRole(e.target.value)}>

                    <option value="patient">患者</option>

                    <option value="doctor">医生</option>

                </select>

                <button onClick={register}>注册</button>

            </div>

            <div>

                <h2>在线问诊</h2>

                <textarea value={description} onChange={e => setDescription(e.target.value)} placeholder="描述病情"></textarea>

                <button onClick={consult}>提交问诊</button>

            </div>

        </div>

    );

}

 

export default App;

三、在线问诊APP开发

在移动互联网时代，开发一款便捷的在线问诊APP是智慧互联网医院系统的重要组成部分。我们可以使用React Native框架来开发跨平台移动应用。

环境搭建

首先，搭建React Native开发环境。安装Node.js后，使用以下命令创建React Native项目：


npx react-native init SmartHospitalApp

cd SmartHospitalApp

npx react-native run-android   或 npx react-native run-ios

开发APP功能

我们将主要实现用户注册和在线问诊功能，与前端网页类似。


import React, { useState } from 'react';

import { View, TextInput, Button, Text, Alert } from 'react-native';

import axios from 'axios';

 

const App = () => {

    const [username, setUsername] = useState('');

    const [password, setPassword] = useState('');

    const [role, setRole] = useState('patient');

    const [description, setDescription] = useState('');

 

    const register = () => {

        axios.post('http://localhost:3000/register', { username, password, role })

            .then(response => {

                Alert.alert(response.data);

            });

    };

 

    const consult = () => {

        axios.post('http://localhost:3000/consult', { patient_id: 1, doctor_id: 1, consultation_time: new Date(), description })

            .then(response => {

                Alert.alert(response.data);

            });

    };

 

    return (

        <View style={{ padding: 20 }}>

            <Text style={{ fontSize: 24 }}>智慧互联网医院</Text>

            <View style={{ marginVertical: 20 }}>

                <Text style={{ fontSize: 18 }}>用户注册</Text>

                <TextInput value={username} onChangeText={setUsername} placeholder="用户名" />

                <TextInput value={password} onChangeText={setPassword} placeholder="密码" secureTextEntry />

                <TextInput value={role} onChangeText={setRole} placeholder="角色（patient或doctor）" />

                <Button title="注册" onPress={register} />

            </View>

            <View style={{ marginVertical: 20 }}>

                <Text style={{ fontSize: 18 }}>在线问诊</Text>

                <TextInput value={description} onChangeText={setDescription} placeholder="描述病情" multiline />

                <Button title="提交问诊" onPress={consult} />

            </View>

        </View>

    );

};

 

export default App;
