Hospital Master-Slave Clock & Time-Sync Solutions
Unified hospital-wide time base and display systems for OR, anesthesia, ICU, radiology, ER, hallways and waiting halls — improving surgical safety and hospital-wide coordination.
Sector Overview
Around OR, anaesthesia, ICU, radiology, ED, corridors, and waiting halls, Yinzhong delivers hospital-grade unified time base and display systems — lifting surgical safety and cross-department coordination.
Why Unified Hospital Time
- Surgical safety — surgery start, anaesthesia, key events: timestamps as legal evidence
- Record integrity — cross-system consistency for HIS / EMR / LIS / RIS / PACS
- MDT — anchor points for remote consults and inter-hospital coordination
- JCI / HIMSS audits — explicit consistency requirements
- Patient communication — visible time in waiting halls and OR family areas
Yinzhong Hospital Stack
Stratum-1 source
- YZ-9810 master/slave, BeiDou + GPS redundant
- NTP exposed to HIS / EMR / business systems
Sub-clock distribution
- OR — YZ-9582 countdown displays, slaved to central
- Wards / corridors — YZ-9580 LED, 3.2" / 4" digits
- Lobby / waiting — giant LED time displays
- Office — silent quartz analog slaves
Architecture
- PoE + network sync — minimal cabling for greenfield
- Retrofit: AC 220V + wireless NTP available
- Single master serves ≥ 500 sub-clocks
Compliance
- NHC Hospital Informatisation Standards
- JCI — event timestamp consistency
- HIMSS EMRAM — audit traceability
- MLPS 2.0 Level 3
OR / anesthesia / birth timestamps still rely on manually read clocks — risking record disputes and legal exposure
Multiple hospital IT systems (HIS/LIS/PACS/anesthesia) are out of sync — EMR timestamps drift apart
Mechanical wall clocks across hallways, waiting halls and offices drift unmaintained
New hospitals need master clocks, cabling and displays planned during fit-out — retrofitting later is costly
Master Clock + Network Sync
YZ-9810 master clock disciplines via BeiDou/GPS, distributes through network switches to every internal system, slave clock and server
OR / Anesthesia Timers
YZ-9580-332S dual-row LED timer supports OR / anesthesia dual timers alongside temperature, humidity and date
Wireless / Wired Mix
Hallways and offices can choose wired or wireless analogue / digital slave clocks — no rewiring, customisable bezels
Hospital-Wide Traceability
All timing and display devices are traceable to the master clock and BeiDou — meeting medical-compliance and forensic requirements
YZ-9200 Master-Slave Clock Solution
End-to-end solution for tertiary and new general hospitals — master clock, network switches, master-slave clock management, Wi-Fi router, plus wireless / wired analogue and digital slave clocks.
