急诊分诊+抢救模块 — 深度设计文档

版本: v1.0 | 编制日期: 2026-06-07 依据: 《急诊科建设与管理指南》+ 《急诊预检分诊专家共识》

---

一、业务背景

急诊是三甲医院的关键科室，必须实现:

• 四级预检分诊(Ⅰ级濒死/Ⅱ级危重/Ⅲ级急症/Ⅳ级非急)
• 绿色通道(胸痛/卒中/创伤)
• 抢救记录电子化
• 急诊绿色通道时间监控(门-药/门-球囊/门-手术)

二、业务流程

患者到达急诊
  ↓
[预检分诊台]
  ├─ 采集生命体征(体温/脉搏/呼吸/血压/血氧/意识)
  ├─ 评估病情分级
  └─ 分配就诊区域
  ↓
┌─ Ⅰ级(濒死) → 立即抢救 → 绿色通道
├─ Ⅱ级(危重) → 10分钟内就诊
├─ Ⅲ级(急症) → 30分钟内就诊
└─ Ⅳ级(非急) → 引导至门诊
  ↓
[急诊医生接诊] ←→ [急诊医嘱]
  ↓
[检查/检验] ←→ [抢救/留观/住院/出院]
  ↓
[急诊病历] ←→ [急诊统计]

三、数据模型

-- 急诊分诊
CREATE TABLE emergency_triage (
    id BIGSERIAL PRIMARY KEY,
    patient_id BIGINT,
    patient_name VARCHAR(50),
    triage_level INT NOT NULL, -- 1-4级
    chief_complaint TEXT,
    temperature DECIMAL(4,1),
    pulse INT,

    systolic_bp INT,
    diastolic_bp INT,
    spo2 INT,
    consciousness VARCHAR(20),
    triage_nurse VARCHAR(64),
    triage_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    area VARCHAR(20), -- RESUS/EMERGENCY/OBSERVATION/GREEN
    status VARCHAR(20) DEFAULT 'WAITING',
    tenant_id BIGINT DEFAULT 0,
    is_deleted INT NOT NULL DEFAULT 0,
    create_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- 抢救记录
