The Second Affiliated Hospital of Hunan University of Chinese Medicine, also known as the Hunan Provincial Hospital of Traditional Chinese Medicine, is a national key TCM hospital with a history dating back to 1934, originally established as Xiang Provincial National Medicine Hospital.
As a Grade A Class III comprehensive TCM hospital, it is renowned as the “Birthplace of Huxiang Traditional Chinese Medicine” and the “Former Site of the Medical Sage”. The hospital integrates medical treatment, education, research, prevention, and rehabilitation, with strong特色 in traditional Chinese medicine combined with modern clinical practice.
The hospital is also a National Clinical Research Base for Traditional Chinese Medicine, operating:
4 National Clinical Key Specialties (Anorectal, Dermatology, Orthopedics & Traumatology, Gynecology)
9 Key Specialties designated by the National Administration of Traditional Chinese Medicine
An annual outpatient and emergency volume exceeding 1 million patient visits
With the continuous advancement of smart hospital construction, the hospital faced increasing challenges in achieving accurate and unified time synchronization across:
46 clinical departments
9 medical technology departments
Multiple buildings and functional zones
Critical scenarios such as multi-device coordination in operating rooms, cross-department consultations, and traceability of TCM preparation processes placed exceptionally high demands on time accuracy and consistency.
Multi-Device Time Drift in Operating Rooms
Time discrepancies at the second level between anesthesia machines, patient monitors, and surgical timers affected the alignment of medical operation timelines required by JCI international accreditation standards.
Traceability Gaps in TCM Preparation Processes
In the hospital’s pharmacy, 18 intelligent decoction machines operated with unsynchronized clocks, causing 3–5 minute discrepancies between preparation batch records and the HIS system.
Low Efficiency in Cross-Building Collaboration
Independent clock systems in Zhongjing Building and the Comprehensive Medical Building resulted in over 200 ms latency between teleconsultation video streams and real-time vital sign data.
Shutai Electronics delivered a hospital-wide, satellite-synchronized time management system, establishing a unified and authoritative time reference for all medical, pharmaceutical, and administrative operations.
