Mobile CT shelter
1Key Takeaways
Mobile CT pods have advantages over fixed CT rooms, such as convenience, speed, and portability. Some already applied mobile CT pods have played important roles in emergency handling and daily public health services, but some problems have emerged: ① Damage to the CT equipment due to inadequate shock protection measure…
2Expert Interpretation
The T/HBYY 0005-2021 standard issued by the Hebei Pharmaceutical Industry Association systematically standardizes the technical requirements for mobile CT cabins for the first time, covering core indicators such as radiation protection, biosafety, and seismic design. It is suitable for epidemic prevention and control and emergency medical scenarios, filling the gap in the industry.
Interpretation of the core content of the standard
| Technical dimension | Traditional CT room | Standard requirements for mobile CT cabin |
|---|---|---|
| Radiation protection | Fixed building protection | 6 sides ≥2.5mmPb lead equivalent, dynamic transportation requires additional reinforcement |
| Biosafety | Basic hospital infection control | BSL-II+ level air purification, mandatory double disinfection system |
| Seismic performance | Not a key consideration | Specialized shock absorption device for the rack + transportation impact test |
Key Technological Breakthroughs
The standard innovatively solves three major industry pain points:
- CT rackTransport shock absorption solution: requires special shock-absorbing bracket + 3mm load-bearing steel plate, vibration displacement ≤0.1mm
- Cross-infection prevention and control: fresh air system ventilation ≥12 times/hour, equipped with hydrogen peroxide spray + ultraviolet double disinfection
- First aid adaptability: the expansion cabin design makes the single side length ≥3.8m, and the stretcher channel width ≥1200mm
Implementation Suggestions
Purchase Configuration Suggestions
- Grounded design (rack ≤300mm from the ground) is preferred to reduce vibration risks
- Air purification and pathogenic microorganism disinfection models should be selected in areas with high incidence of epidemics
- Vehicle-mounted models must be equipped with a ≥4KW UPS power system
Key points of operation and maintenance
- High-efficiency filter leakage detection (DOP method) every month
- All movable parts must be fixed before transportation, and the protective equipment cabinet must be locked
- Typhoon-proof wire rope reinforcement devices must be activated during typhoon warnings
Background of standard evolution
The COVID-19 pandemic exposed the mobility defects of traditional CT equipment. In 2020, the temporary CT installation in Wuhan Fangcang Hospital took up to 72 hours. This standard for the first time incorporates mobile solutions such as vehicle-mounted CT and Fangcang CT into standardized management, and its technical indicators have added 12 special requirements compared to GBZ 130-2020.
