基于PyQt5的图形化界面开发——模拟医院管理系统

0. 前言

本节以医院管理系统为例，使用PyQt5模拟医院系统的功能。

本次用到的数据结构思想为队列，使用队列能够更真实的反映医院排队等候的情况（先挂号者先就诊），事实上

操作系统：Windows10 专业版

开发环境：Pycahrm Comunity 2022.3

Python解释器版本：Python3.8

第三方库：PyQt5

如果你还不会安装第三方库，你可以参考我的这篇文章进行学习：
Python第三方库安装——使用vscode、pycharm安装Python第三方库

网盘已经超出了2400个G存不进东西，不能通过网盘来分享了，代码应该如何复制我把它们放在了结尾。

1. 需求分析

• 功能1：挂号
  用户能够填写自己的挂号信息，如姓名、年龄、电话、挂号科室等。

• 功能2：模拟就诊并开药
  根据用户的挂号科室为其诊断出病因，并且为其开相应药物，由于此模拟系统只能给出医生的反馈（病因+药物），所以我们只能给出随机的病因分配来模拟此功能（我可不是医生）。

• 功能3：各科室信息查询
  展示所有科室正在等待的挂号者顺序

• 功能4：中途离开
  如若中途离开（感觉身体舒服了很多选择不看病）

• 功能5：退出界面
  按下此按键即退出挂号系统

• 管理员功能：保存本次操作信息至redis数据库 / 读取之前保存的信息
  

2. 挂号界面的思路、UI界面代码及相应触发函数

2.1 思路分析

挂号界面当然是需要让用户填写个人信息，这里我们要求填写姓名、年龄、电话号和挂号科室。

填写完成后点击确定将有文本框提示挂号成功。

为避免恶意重复挂号或者不小心挂了多个号造成用户不必要的开支，还需要添加重复挂号的提示。如下图，重复挂号将提示重复挂号。

我们给小倒霉多挂几个号，让他有助于我们接下来的操作：

2.2 ui_guahao.py

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(586, 354)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(170, 60, 41, 41))
        self.label.setObjectName("label")
        self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit.setGeometry(QtCore.QRect(230, 70, 113, 21))
        self.lineEdit.setObjectName("lineEdit")
        self.label_2 = QtWidgets.QLabel(self.centralwidget)
        self.label_2.setGeometry(QtCore.QRect(170, 110, 41, 41))
        self.label_2.setObjectName("label_2")
        self.lineEdit_2 = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit_2.setGeometry(QtCore.QRect(230, 120, 113, 21))
        self.lineEdit_2.setObjectName("lineEdit_2")
        self.label_3 = QtWidgets.QLabel(self.centralwidget)
        self.label_3.setGeometry(QtCore.QRect(170, 160, 41, 41))
        self.label_3.setObjectName("label_3")
        self.lineEdit_3 = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit_3.setGeometry(QtCore.QRect(230, 170, 113, 21))

        self.comboBox.setObjectName("comboBox")
        self.comboBox.addItem("")
        self.comboBox.addItem("")

        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(420, 260, 93, 28))
        self.pushButton.setObjectName("pushButton")
        self.pushButton_2 = QtWidgets.QPushButton(self.centralwidget)

        self.pushButton_2.setObjectName("pushButton_2")
        self.label_5 = QtWidgets.QLabel(self.centralwidget)
        self.label_5.setGeometry(QtCore.QRect(0, 240, 581, 20))
        self.label_5.setText("")
        self.label_5.setObjectName("label_5")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 586, 26))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.label.setText(_translate("MainWindow", "姓名"))
        self.label_2.setText(_translate("MainWindow", "年龄"))
        self.label_3.setText(_translate("MainWindow", "电话"))
        self.comboBox.setItemText(0, _translate("MainWindow", "内科"))
        self.comboBox.setItemText(1, _translate("MainWindow", "外科"))

        self.comboBox.setItemText(3, _translate("MainWindow", "儿科"))
        self.comboBox.setItemText(4, _translate("MainWindow", "皮肤科"))
        self.comboBox.setItemText(5, _translate("MainWindow", "眼科"))
        self.label_4.setText(_translate("MainWindow", "挂号科室"))
        self.pushButton.setText(_translate("MainWindow", "确定"))
        self.pushButton_2.setText(_translate("MainWindow", "返回"))

2.3 相应的触发函数代码

这个函数的功能是将在用户点击确定后提示挂号成功或者重复挂号，然后选择是否将其添加进列表中。

# get_info 挂号
# 已有功能，添加病人
def get_info_guahao(ui):
    # 挂号信息获取
    name = ui.lineEdit.text()
    year = ui.lineEdit_2.text()
    phone = ui.lineEdit_3.text()
    keshi = ui.comboBox.currentText()

    human = [name,year,phone,keshi]
    if human not in type_room_dict[keshi]:
        type_room_dict[keshi].append(human)
        ui.label_5.setText("{}:{}挂号{}成功".format(time.asctime(time.localtime(time.time())),name,keshi))
    else:
        ui.label_5.setText("{}:{}已在{}挂号，请勿重复挂号".format(time.asctime(time.localtime(time.time())),name, keshi))

3. 就诊界面的思路、UI界面代码及相应触发函数

3.1 思路分析

用户选择自己的科室和姓名，在点击确定后下方文本框给出就诊结果分析。

接下来就是给小倒霉看病就诊的环节：

小倒霉还是比较幸运，在我们的随机函数中抽中了轻度感冒，也不需要花钱开药。当然最重要的还是小倒霉身体无恙。

        self.label_3.setText(_translate("MainWindow", "祝您早日康复!"))
        self.pushButton.setText(_translate("MainWindow", "查询"))

3.3 相关触发函数：随机分配症状函数，对症下药函数，就诊函数（看完病自动离开队列）

# 就诊函数
# 病人就诊后离队
def get_info_jiuzhen(ui):
    keshi = ui.comboBox.currentText()

            ill = hospital.illness(keshi)
            medi = hospital.medicine(ill)
            ui.label_2.setText("诊断结果:{} {}".format(ill,medi))
            type_room.remove(i) # 就诊后离开队伍
            print(type_room)
            return

    ui.label_2.clear()

4. 离开界面的思路、UI界面代码及相应触发函数

4.1 思路分析

离开界面比较轻松，函数功能比较简单，只需要编写将其从队伍中移除的函数即可。

4.3相应触发函数：离开函数

只需要一个函数就好啦

# get_info 离开队伍
def get_info_likai(ui):
    keshi = ui.comboBox.currentText()
    name = ui.lineEdit.text()
    ui.label_2.setText("{}:{}科室{}:已为您取消排队，您现在可以离开".format(time.asctime(time.localtime(time.time())),keshi,name))
    print(keshi,name)

5. 各科室信息查询界面的思路、UI界面代码及相应触发函数

5.1 思路分析

需要将每一个科室的信息放至界面中，为了使界面更加合理，应该使用一个表格来放置，如下：

应该使用 tableview 或者 tableweight 。

5.2 ui_info.py

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(572, 351)

        self.tableWidget.setGeometry(QtCore.QRect(20, 50, 531, 241))
        self.tableWidget.setObjectName("tableWidget")
        self.tableWidget.setColumnCount(4)
        self.tableWidget.setRowCount(0)
        item = QtWidgets.QTableWidgetItem()
        self.tableWidget.setHorizontalHeaderItem(0, item)
        item = QtWidgets.QTableWidgetItem()
        self.tableWidget.setHorizontalHeaderItem(1, item)
        item = QtWidgets.QTableWidgetItem()
        self.tableWidget.setHorizontalHeaderItem(2, item)
        item = QtWidgets.QTableWidgetItem()
        self.tableWidget.setHorizontalHeaderItem(3, item)
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 572, 26))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "各科室信息"))
        self.pushButton.setText(_translate("MainWindow", "返回"))
        self.pushButton_2.setText(_translate("MainWindow", "刷新"))
        item = self.tableWidget.horizontalHeaderItem(0)
        item.setText(_translate("MainWindow", "姓名"))
        item = self.tableWidget.horizontalHeaderItem(1)
        item.setText(_translate("MainWindow", "年龄"))
        item = self.tableWidget.horizontalHeaderItem(2)
        item.setText(_translate("MainWindow", "电话"))
        item = self.tableWidget.horizontalHeaderItem(3)
        item.setText(_translate("MainWindow", "科室"))

5.3 相关触发函数：刷新函数

在点击刷新后将显示最新的信息：

def show_info(ui):
    # 清空表中数据
    ui.tableWidget.setRowCount(0)
    ui.tableWidget.clearContents()
    for k in ["内科","外科","儿科","皮肤科","眼科","妇科"]:
        items = type_room_dict[k]
        for i in range(len(items)):
            item = items[i]

需要绘制这个主界面，还需要有相关的页面跳转函数

7.注意事项

可能大家并未太多接触到数据库部分，所以在管理员功能方面暂时不开发。

如果你想借鉴我的代码来尝试运行效果，那么在你的工程目录下，应该是如此的结构，文件命名记得不要弄错：
