Project Background

Blood sample transportation in hospitals refers to the process of safely and rapidly delivering collected blood specimens from collection points to laboratory facilities for testing. This process must ensure that samples remain intact, uncontaminated, and effective throughout transport to guarantee testing accuracy.

Hospitals typically rely on specialized biological isolation transport systems to prevent environmental factors from affecting the specimens. Maintaining the correct temperature, monitoring key conditions, and ensuring timely delivery are essential to supporting accurate diagnostics and clinical decision-making. A reliable and efficient blood sample transportation system is therefore crucial for modern medical laboratories.

Solution Overview

Main Controller: Siemens S7-1200 PLC
Application Process: Biological isolation transportation
Project I/O Configuration:
2RS-PN2 + 516DI + 616DO + 18AI
Annual Usage Volume: 50,000 units

To meet the hospital’s requirements, a Siemens S7-1200 PLC was integrated with our custom IO modules to build a highly reliable medical blood sample transportation control system. The system supports multiple types of sensor inputs, including:

• Temperature sensors

• Humidity sensors

• Position sensors

• Environmental condition sensors

• Sample location feedback

During real-time transportation, the PLC processes data from all sensors to ensure the proper operating state of key components such as the power drive system, refrigeration units, and alarm modules. This ensures that blood samples are kept under optimal temperature and environmental conditions until they are delivered to the laboratory safely and without delay.

Through intelligent monitoring and automated control, the system significantly enhances the security, stability, and traceability of blood sample transportation.

Application Advantages

High-Speed Response, Fully Meeting Customer Requirements

• Real-time environmental monitoring ensures stable temperature and humidity during transport

• Automated alarms trigger instant protection mechanisms when abnormalities occur

• Stable PLC-based control guarantees high reliability suitable for medical-grade operations

• Flexible sensor integration supports expansion and future digital upgrades

This intelligent solution ensures that hospitals can maintain strict sample integrity and accelerate their diagnostic processes.

Project Outcome

After implementation, the Shanghai Xuanqiao Hospital blood sample transportation system achieved significant improvements in workflow efficiency and testing accuracy. The automated platform reduced manual handling, minimized sample contamination risks, and ensured that every sample reached the laboratory under ideal conditions. The solution fully met the hospital’s expectations for speed, safety, and reliability, supporting high-quality medical testing and improved patient care.
