Functional Analysis of Hospital Emergency Call Systems: Building an Efficient Smart Healthcare Response Framework

Against the backdrop of ongoing advancements in smart hospital

development, hospital emergency call systems have become 

indispensable infrastructure for modern medical institutions. 

Compared to traditional bedside call devices, next-generation 

hospital emergency call systems leverage IoT technology to 

achieve comprehensive ward coverage, real-time data 

interoperability, and intelligent management, significantly 

enhancing nursing efficiency and patient safety assurance 

capabilities.

This article comprehensively analyzes hospital emergency 

call system solutions from perspectives including system

architecture, core functions, system integration, 

and application value.

I. What is a Hospital Emergency Call System?

A hospital emergency call system is an intelligent 

communication system deployed within hospital wards. 

Covering areas such as nursing stations, ward entrances,

bedside terminals, and restrooms, it enables integrated 

management of patient calls, medical staff response, 

data synchronization, and emergency handling.

Its core objectives include:

- Accelerating emergency call response times

- Reducing administrative workload for medical staff

- Enabling real-time data integration with HIS systems

- Strengthening ward safety management capabilities

II. Overall Architecture of Hospital Emergency 

Call Systems

Modern hospital emergency call systems typically 

comprise three core modules:

1. Nurse Station Host (Central Control Unit)

The nurse station host serves as the system's 

command center, responsible for receiving and 

distributing all ward call information.

Primary functions include:

Real-time monitoring of all bedside patient 

information

Support for ward-wide announcements and 

call forwarding

Automatic call holding for unanswered calls

Dual power backup system ensuring stable

operation

Support for cloud server disaster recovery 

solutions

Automatic switchover to backup power

during outages

Through multiple safeguards, the hospital 

emergency call system achieves 24/7 

uninterrupted operation.

2. Ward Door Station System

Ward door stations serve as critical 

information display and status notification 

terminals connecting patients with 

medical staff.

Core Functions:

Display patient information and care level

Synchronize medical team information

Support infrared personnel recognition

Support mask-wearing status detection

Contactless check-in functionality

Three-color door light linkage system

The hospital emergency call system 

enables remote visual alarm management

via three-color door lights:

Red: Restroom emergency call

Blue: Nursing request

Green: Physician call

This design significantly reduces medical 

staff response time and enhances 

emergency incident handling efficiency.

3. Bedside Terminal System

The bedside terminal is the patient-facing

interaction device within the hospital 

emergency call system.

Primary Configuration & Functions:

Dual mechanical button design (Physician 

call / Nursing request)

One-touch emergency call function

Real-time display of patient basic information

Synchronization with HIS system medical 

order data

Display of care level and dietary restrictions

Automatic linkage of allergy history information

By integrating with the HIS system, the hospital 

emergency call system enables automatic data 

synchronization, reducing manual entry errors 

and improving information accuracy.

III. Specialized Security Function Design

Restroom Emergency Alarm System

The hospital emergency call system covers 

high-risk restroom areas using:

Pull-cord trigger mode

Button trigger mode

Interlocking with red alarm lights on 

door intercoms

This design effectively addresses 

emergencies like falls or sudden 

illnesses, enabling sub-second 

response times.

Smart Nursing Information Display

The smart nursing screen 

dynamically displays:

Inpatient statistics

Nursing level distribution

Surgical schedules

Medical staff duty rosters

Laboratory report information

Enabling ward data visualization 

management and enhancing nursing 

collaboration efficiency.

IV. System Integration Capabilities 

and Scalability

An outstanding hospital emergency 

call system must possess robust 

integration capabilities.

Data Interoperability

Bedside terminals directly access 

HIS system data

Nursing screens synchronously 

display lab reports

Automatically link patient IDs to 

medical records

Hardware Compatibility

Supports 7–15.3-inch multi-size 

screens

Compatible with various medical 

device interfaces (e.g., ventilators)

Expandable IoT terminal devices

Highly adaptable design enables the 

system to serve healthcare facilities

of all scales.

V. Application Value of Hospital 

Emergency Call Systems

Based on actual application data, 

next-generation hospital emergency 

call systems achieve:

Over 30% reduction in paperwork

Emergency response times shortened 

to under 20 seconds

Significantly enhanced nursing efficiency

More standardized ward safety management

Through three-color door lights, automatic data

synchronization, and intelligent dispatch 

mechanisms, hospital emergency call systems 

have evolved from “passive response” to 

“proactive management.”
