基于ASP.NET Core的医院输血审核系统设计与实现
一、项目概述
医院输血审核系统是针对医疗场景中的输血申请进行分级审批的Web应用系统。该系统实现了诊疗组长、科主任、医务部三级审核流程，确保输血申请的安全性和合规性。系统同时支持移动端（钉钉小程序）和Web端访问，采用多数据库架构整合医院现有的HIS系统、输血系统等多个数据源。
1.1 技术栈
| 层级 | 技术选型 |
|---|---|
| 框架 | ASP.NET Core 3.1/5.0 |
| 数据库 | MSSQL (SIHIS)、Oracle (HIS3)、MySQL (QASystem) |
| 前端 | Layui + HTML |
| 移动端 | 钉钉小程序 (DingTalk Mini App) |
| 日志 | Microsoft.Extensions.Logging |

└─────────────────┘二、核心模型设计
2.1 输血申请审核模型
csharp
public class BloodApplyApproveModel
{
public string ApplyNo { get; set; } // 申请单号
public string ItemNo { get; set; } // 项目编号
public bool SuperiorApproveFlag { get; set; } // 诊疗组长审核标志
public string SuperiorApproveUser { get; set; } // 诊疗组长审核人
public string SuperiorApproveTime { get; set; } // 诊疗组长审核时间
public bool ProfessorApproveFlag { get; set; } // 科主任审核标志
public string ProfessorApproveUser { get; set; } // 科主任审核人
public string ProfessorApproveTime { get; set; } // 科主任审核时间
public bool MedApproveFlag { get; set; } // 医务部审核标志
public string MedApproveUser { get; set; } // 医务部审核人
public string MedApproveTime { get; set; } // 医务部审核时间
public int ApproveStatus { get; set; } // 审核状态
}2.2 审核请求模型
csharp
public class BloodPmsModel
{
public string ApplyNo { get; set; } // 申请单号
public string ApplyLevel { get; set; } // 申请类别 (1-诊疗组长, 2-科主任, 3-医务部)
public string EmpNo { get; set; } // 员工编号
}2.3 输血系统更新模型
csharp
public class BloodInfoModel
{
public string ITEMNO { get; set; } // 项目编号
public string SHANGJIYS { get; set; } // 上级医生
public string SHANGJISHSJ { get; set; } // 上级审核时间
public string KEZHUREN { get; set; } // 科主任
public string KEZHURENSHSJ { get; set; } // 科主任审核时间
public string YWB { get; set; } // 医务部
public string YWBSHSJ { get; set; } // 医务部审核时间
}三、控制器核心实现
3.1 构造函数与依赖注入
csharp
public class BloodTransAuditController : Controller
{
private readonly string _qasystem;
private readonly string _harmfulevent;
private readonly string _deepthroat;
private readonly string _his3;
private readonly string _sihis;
private readonly IMysqlService _mysqlService;
private readonly IOracleService _oracleService;
private readonly IMssqlService _mssqlService;
public BloodTransAuditController(
ILogger<BloodTransAuditController> logger,
IConfiguration configuration,
IMysqlService mysqlService,
IOracleService oracleService,
IMssqlService mssqlService)
{
_qasystem = configuration.GetConnectionString("qasystem");
_his3 = configuration.GetConnectionString("his3");
_sihis = configuration.GetConnectionString("sihis");
_mysqlService = mysqlService;
_oracleService = oracleService;
_mssqlService = mssqlService;
}
}设计亮点：通过配置文件管理多数据库连接字符串，便于部署切换不同环境。
3.2 分级审核逻辑实现
审核核心逻辑根据ApplyLevel参数执行不同的审核流程：
csharp
if (model.ApplyLevel == "1") // 诊疗组长
{
if (isSuperiorApprove(model.ApplyNo) == false)
{
// 更新审核状态
sql = @"update BloodApplyApprove
set SuperiorApproveFlag=@SuperiorApproveFlag,
SuperiorApproveUser=@SuperiorApproveUser,
SuperiorApproveTime=@SuperiorApproveTime,
ApproveStatus = @ApproveStatus,
IsMobile=1
where ApplyNo=@ApplyNo";
BackStaus = _mssqlService.DBExecute(_sihis, sql,
new BloodApplyApproveModel {
SuperiorApproveFlag = true,
SuperiorApproveUser = model.EmpNo,
SuperiorApproveTime = dateTime,
ApproveStatus = 1,
ApplyNo = model.ApplyNo
});
// 同步更新输血系统
usql = @"UPDATE xueye.xy_xd_bloodinfo
SET SHANGJIYS=:SHANGJIYS,
SHANGJISHSJ=to_date(:SHANGJISHSJ,'yyyy-MM-dd hh24:mi:ss')
where ITEMNO=:ITEMNO";
_oracleService.DBExecute(_his3, usql,
new BloodInfoModel { SHANGJIYS = model.EmpNo, SHANGJISHSJ = dateTime, ITEMNO = ItemNo });
}
}3.3 审核状态检查方法
csharp
private bool isSuperiorApprove(string ApplyNo)
{
string sql = "select * from BloodApplyApprove where ApplyNo=@ApplyNo";
BloodApplyApproveModel bloodApplyApprove =
_mssqlService.DBFind<BloodApplyApproveModel>(_sihis, sql,
new BloodApplyApproveModel { ApplyNo = ApplyNo });
return bloodApplyApprove == null ? false : bloodApplyApprove.SuperiorApproveFlag;
}
private bool isProfessorApprove(string ApplyNo)
{
string sql = "select * from BloodApplyApprove where ApplyNo=@ApplyNo";
BloodApplyApproveModel bloodApplyApprove =
_mssqlService.DBFind<BloodApplyApproveModel>(_sihis, sql,
new BloodApplyApproveModel { ApplyNo = ApplyNo });
return bloodApplyApprove == null ? false : bloodApplyApprove.ProfessorApproveFlag;
}
private bool isMedApprove(string ApplyNo)
{
string sql = "select * from BloodApplyApprove where ApplyNo=@ApplyNo";
BloodApplyApproveModel bloodApplyApprove =
_mssqlService.DBFind<BloodApplyApproveModel>(_sihis, sql,
new BloodApplyApproveModel { ApplyNo = ApplyNo });
return bloodApplyApprove == null ? false : bloodApplyApprove.MedApproveFlag;
}四、多数据库架构设计
4.1 数据库职责划分
| 数据库 | 类型 | 用途 |
|---|---|---|
| SIHIS | MSSQL | 审核主数据存储 |
| HIS3 | Oracle | 输血系统数据同步 |
| QASystem | MySQL | 系统业务数据 |
4.2 数据同步策略
系统采用双写策略：当审核通过时，同时更新MSSQL审核库和Oracle输血库，确保数据一致性：
csharp
// 1. 更新审核数据库 (MSSQL)
BackStaus = _mssqlService.DBExecute(_sihis, sql, approveModel);
// 2. 同步更新输血系统 (Oracle)
_oracleService.DBExecute(_his3, usql, bloodInfoModel);五、双端适配实现
5.1 Web端审核 (HTTP GET)
csharp
[HttpGet]
public IActionResult Index(string ApplyNo, string ApplyLevel, string EmpNo)
{
// 审核逻辑...
if (BackStaus > 0)
{
return Redirect("dingtalk://dingtalkclient/action/open_mini_app?miniAppId=5000000004689541&page=pages%2Fsuccess%2Fsuccess%3Fx%3D%25E4%25B8%25AD%25E6%2596%2587");
}
else
{
return Redirect("dingtalk://dingtalkclient/action/open_mini_app?miniAppId=5000000004689541&page=pages%2Ffail%2Ffail%3Fx%3D%25E4%25B8%25AD%25E6%2596%2587");
}
}5.2 移动端审核 (HTTP POST)
csharp
[HttpPost]
public JsonResult Audit(BloodPmsModel model)
{
MsgModel msgObj = null;
try
{
// 审核逻辑...
if (BackStaus > 0)
{
msgObj = new MsgModel { code = 1, msg = "输血审核成功" };
}
else
{
msgObj = new MsgModel { code = 0, msg = "输血审核失败" };
}
}
catch (Exception ex)
{
msgObj = new MsgModel { code = 0, data = ex.Message, msg = "输血审核失败" };
}
return Json(msgObj);
}5.3 钉钉小程序跳转协议
csharp
// 成功跳转
"dingtalk://dingtalkclient/action/open_mini_app?miniAppId=5000000004689541&page=pages%2Fsuccess%2Fsuccess"
// 失败跳转
"dingtalk://dingtalkclient/action/open_mini_app?miniAppId=5000000004689541&page=pages%2Ffail%2Ffail"六、钉钉消息推送机制
6.1 消息推送架构
系统实现了智能化的钉钉消息推送机制，当有新的输血申请需要审核时，自动根据血量和科室规则计算审核人并推送钉钉消息：
csharp
[Route("JdrmyyCloud/sendDingTalkMessageOfBloodApply")]
[HttpPost]
public string sendDingTalkMessageOfBloodApply(DingTalkMsgModel model)
{
string title = "输血申请";
string ItemName = getItemNameByItemNo(model.ItemNo);
decimal ApplyQty = totalApplyQty(model.VisitNo).ToString("#.####");
List<BloodApplyerModel> bloodApplyers = getEmpCodes(model);
foreach (BloodApplyerModel bloodApplyer in bloodApplyers)
{
string ApplyClass = string.Empty;
if (bloodApplyer.ApplyLevel == "1")
ApplyClass = "上级医生审核";
else if (bloodApplyer.ApplyLevel == "2")
ApplyClass = "科主任审核";
else if (bloodApplyer.ApplyLevel == "3")
ApplyClass = "医务部审核";
string content = $"**输血申请审核提醒：** \n\n ------ \n\n **审核类别：** {ApplyClass} \n\n **病历号：** {model.ChartNo} \n\n **病人姓名：** {getPatientByChartNo(model.ChartNo)} \n\n **当日累计：** {ApplyQty}ml \n\n **申请内容：** {ItemName} \n\n **申请时间：** {DateTime.Now.ToString("yyyy-MM-dd HH:mm")}";
string EmpNo = getEmployeeByEmpCode(bloodApplyer.EmpCode);
string EnCodeUrl = HttpUtility.UrlEncode($"pages/index/index?ApplyLevel={bloodApplyer.ApplyLevel}&ApplyNo={model.ApplyNo}&EmpNo={EmpNo}");
string SingleUrl = $"dingtalk://dingtalkclient/action/open_mini_app?miniAppId=5000000004689541&page={EnCodeUrl}";
string msg = SendBloodAuditMsg(title, content, bloodApplyer.EmpCode, "点击审核", SingleUrl);
}
return model.ApplyNo;
}6.2 智能审核路由算法
系统根据《医疗机构临床用血管理办法》实现了智能审核路由，根据当日累计用血量自动判定需要哪些级别的审核：
csharp
private List<BloodApplyerModel> getEmpCodes(DingTalkMsgModel model)
{
decimal ApplyQty = totalApplyQty(model.VisitNo);
DataTable dt = DBFactory.SIHealthCareObject.ExecuteDataTable(
"select * from BloodApplyApprove where ApplyNo=@ApplyNo",
new SqlParameter("@ApplyNo", model.ApplyNo));
List<BloodApplyerModel> BloodApplyers = new List<BloodApplyerModel>();
if (dt.Rows.Count > 0)
{
// 规则1: 当日累计 < 800ml → 诊疗组长审核
if (ApplyQty < 800)
{
if (dt.Rows[0]["SuperiorApproveFlag"].ToString() == "False")
{
if ((model.deptId == "10091") || (model.deptId == "10093"))
BloodApplyers.Add(new BloodApplyerModel { EmpCode = getEmergencySuperiorerEmp(model.deptId), ApplyLevel = "1" });
else
BloodApplyers.Add(new BloodApplyerModel { EmpCode = getMedicalGroupEmp(model.VisitNo), ApplyLevel = "1" });
}
}
// 规则2: 800ml ≤ 当日累计 < 1600ml → 诊疗组长 + 科主任
else if (ApplyQty >= 800 && ApplyQty < 1600)
{
if (dt.Rows[0]["SuperiorApproveFlag"].ToString() == "False")
{
BloodApplyers.Add(new BloodApplyerModel { EmpCode = getMedicalGroupEmp(model.VisitNo), ApplyLevel = "1" });
}
if (dt.Rows[0]["ProfessorApproveFlag"].ToString() == "False")
{
BloodApplyers.Add(new BloodApplyerModel { EmpCode = getDeptHeader(model.deptId), ApplyLevel = "2" });
}
}
// 规则3: 当日累计 ≥ 1600ml → 科主任 + 医务部
else if (ApplyQty >= 1600)
{
if (dt.Rows[0]["ProfessorApproveFlag"].ToString() == "False")
{
BloodApplyers.Add(new BloodApplyerModel { EmpCode = getDeptHeader(model.deptId), ApplyLevel = "2" });
}
if (dt.Rows[0]["MedApproveFlag"].ToString() == "False")
{
BloodApplyers.Add(new BloodApplyerModel { EmpCode = getDeptHeader("10168"), ApplyLevel = "3" });
}
}
}
return BloodApplyers;
}6.3 用血量计算规则
csharp
private decimal totalApplyQty(string VisitNo)
{
string sql = @"select sum(a.ApplyQty) as ApplyQty
from BloodApplyApprove a, MedItem b
where a.ItemNo = b.ItemNo
and a.VisitNo=@VisitNo
and CONVERT(varchar(100), a.ApplyTime, 112) = CONVERT(varchar(100), GETDATE(), 112)
and a.IsDel=0
and b.TreatStatus not in ('9', 'C')";
object ApplyQty = DBFactory.SIHealthCareObject.ExecuteScalar(sql, new SqlParameter("@VisitNo", VisitNo));
return ApplyQty == null ? 0 : Convert.ToDecimal(ApplyQty);
}6.4 审核人获取逻辑
| 科室类型 | 审核级别 | 获取方式 |
|---|---|---|
| 急诊内科/外科 | 诊疗组长 | getEmergencySuperiorerEmp(deptId) - 查询急诊科上级医生表 |
| 普通科室 | 诊疗组长 | getMedicalGroupEmp(VisitNo) - 查询诊疗组与角色关联表 |
| 全科室 | 科主任 | getDeptHeader(deptId) - 查询科室主任表 |
| 全科室 | 医务部 | getDeptHeader("10168") - 固定医务部科室编码 |
csharp
private string getMedicalGroupEmp(string VisitNo)
{
string sql = @"select * from Employee where EmpNo in (
select a.EmpNo from EmpUserRole a, MedicalGroupRef b
where a.EmpNo = b.EmpNo and a.RoleNo='870410'
and b.MedicalGroupNo in (select MedicalGroupNo from InPatient where VisitNo = @VisitNo))";
DataTable dt = DBFactory.SIHealthCareObject.ExecuteDataTable(sql, new SqlParameter("@VisitNo", VisitNo));
return dt.Rows.Count == 0 ? "" : dt.Rows[0]["EmpCode"].ToString();
}
private string getDeptHeader(string deptId)
{
string sql = "select * from Employee where EmpNo in (select EmpNo from Blood_DeptHeader where DeptNo=@DeptNo)";
DataTable dt = DBFactory.SIHealthCareObject.ExecuteDataTable(sql, new SqlParameter("@DeptNo", deptId));
return dt.Rows.Count == 0 ? "" : dt.Rows[0]["EmpCode"].ToString();
}6.5 钉钉消息发送实现
csharp
private string SendBloodAuditMsg(string title, string content, string empCode, string SingleTitle, string SingleUrl)
{
string Appkey = "dingbwxvrnfnjq0qzahn";
string Appsecret = "KAdjZGc81SeSyH_HJYki-_WaAirvYP7D54ThGRD8BQRsh6hqnJU4CFZepXXI9oiE";
long AgentId = 757344095L;
// 获取AccessToken
IDingTalkClient client1 = new DefaultDingTalkClient("https://oapi.dingtalk.com/gettoken");
OapiGettokenRequest req1 = new OapiGettokenRequest();
req1.Appkey = Appkey;
req1.Appsecret = Appsecret;
OapiGettokenResponse rsp1 = client1.Execute(req1);
RequestTokenModel requestToken = JsonConvert.DeserializeObject<RequestTokenModel>(rsp1.Body);
if (requestToken.errcode == 0)
{
// 根据工号获取手机号
string mobile = getMobileByEmpCode(empCode);
// 通过手机号获取userId
IDingTalkClient client2 = new DefaultDingTalkClient("https://oapi.dingtalk.com/user/get_by_mobile");
OapiUserGetByMobileRequest req2 = new OapiUserGetByMobileRequest();
req2.Mobile = mobile;
OapiUserGetByMobileResponse rsp2 = client2.Execute(req2, requestToken.access_token);
RequestUserIdModel requestUserId = JsonConvert.DeserializeObject<RequestUserIdModel>(rsp2.Body);
if (requestUserId.errcode == 0)
{
// 发送ActionCard类型消息
IDingTalkClient client3 = new DefaultDingTalkClient("https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2");
OapiMessageCorpconversationAsyncsendV2Request req3 = new OapiMessageCorpconversationAsyncsendV2Request();
req3.AgentId = AgentId;
req3.UseridList = requestUserId.userid;
OapiMessageCorpconversationAsyncsendV2Request.MsgDomain msg = new OapiMessageCorpconversationAsyncsendV2Request.MsgDomain();
msg.Msgtype = "action_card";
OapiMessageCorpconversationAsyncsendV2Request.ActionCardDomain actionCard = new OapiMessageCorpconversationAsyncsendV2Request.ActionCardDomain();
actionCard.Title = title;
actionCard.Markdown = content;
actionCard.SingleTitle = SingleTitle;
actionCard.SingleUrl = SingleUrl;
msg.ActionCard = actionCard;
req3.Msg_ = msg;
OapiMessageCorpconversationAsyncsendV2Response rsp3 = client3.Execute(req3, requestToken.access_token);
return JsonConvert.DeserializeObject<RequestMessageModel>(rsp3.Body).request_id;
}
}
return "发送失败";

└─────────────────────────────────────────────────────────────────┘九、代码优化建议
9.1 重复代码提取
当前Audit和Index方法存在大量重复逻辑，建议抽取为私有方法：
csharp
private int ExecuteAudit(string applyNo, string applyLevel, string empNo)
{
string sql = string.Empty;
string usql = string.Empty;
string dateTime = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
int backStatus = 0;
string itemNo = getItemNoByApplyNo(applyNo);
try
{
switch (applyLevel)
{
case "1": // 诊疗组长
backStatus = ApproveBySuperior(applyNo, empNo, dateTime, itemNo);
break;
case "2": // 科主任
backStatus = ApproveByProfessor(applyNo, empNo, dateTime, itemNo);
break;
case "3": // 医务部
backStatus = ApproveByMed(applyNo, empNo, dateTime, itemNo);
break;
}
}
catch (Exception ex)
{
throw new AuditException($"审核失败: {ex.Message}", applyNo, applyLevel, empNo);
}
return backStatus;
}9.2 事务管理优化
当前双写操作缺乏事务保证，建议引入分布式事务：
csharp
using (var transaction = new TransactionScope())
{
_mssqlService.DBExecute(_sihis, sql, approveModel);
_oracleService.DBExecute(_his3, usql, bloodInfoModel);
transaction.Complete();
}9.3 审核状态机重构
使用状态模式替代多层if-else：
csharp
public interface IAuditStrategy
{
bool CanApprove(string applyNo);
int Approve(string applyNo, string empNo, string dateTime);
string GetAuditLevel();
}
public class SuperiorAuditStrategy : IAuditStrategy
{
public bool CanApprove(string applyNo) => !_service.isSuperiorApprove(applyNo);
public int Approve(string applyNo, string empNo, string dateTime) { /* ... */ }
}十、总结
本文详细介绍了基于ASP.NET Core的医院输血审核系统设计与实现，该系统具有以下特点：
- 多数据库整合：同时连接MSSQL、Oracle、MySQL三种数据库，实现医院现有系统的数据打通
- 分级审核机制：支持诊疗组长、科主任、医务部三级审核流程
- 双端适配：同时支持Web端和移动端（钉钉小程序）访问
- 智能消息推送：根据用血量自动计算审核路由，钉钉消息一键直达审核页面
- 日志完善：全面的操作日志记录，便于审计追踪
10.1 关键技术亮点
| 功能模块 | 技术方案 | 业务价值 |
|---|---|---|
| 用血量阈值判断 | 800ml/1600ml双阈值 | 符合《医疗机构临床用血管理办法》 |
| 审核人路由 | 科室+角色+诊疗组多维度 | 确保审批层级正确 |
| 钉钉消息 | ActionCard + DeepLink | 点击消息直接进入审核页 |
| 跨库同步 | MSSQL + Oracle双写 | 审核库与输血系统数据一致 |
系统可进一步优化的地方包括：审核逻辑抽象化、分布式事务引入、审核状态机重构、缓存机制添加等，以提升系统的可维护性和性能。
