Research on Technical Characteristics and Engineering Application of High-Pressure Inflatable Medical Tents
Abstract
Centered on a high-pressure rigid air column structure, high-pressure inflatable medical tents integrate key technologies such as rapid deployment, extreme environment tolerance, medical airtightness and modular customization. They can quickly construct compliant temporary medical treatment units in high-altitude, frigid, strong wind, heavy snow and disaster sites, meeting the needs of emergency medical scenarios such as critical care, triage, aseptic disposal and mobile hospitals. From the dimensions of structural design, core performance, material technology, customized solutions, application scenarios and engineering support, this paper systematically expounds its technical principles, index system and practical value, providing a technical basis for the selection and deployment of emergency medical equipment.

1 Introduction
Traditional tents and metal frame temporary medical buildings generally have problems such as time-consuming construction, insufficient structural stability, poor airtightness, complex maintenance and inconvenient transportation under extreme conditions such as high altitude, severe cold and heat, and heavy wind and snow. Adopting 500–1000 KPa high-pressure arched air columns to form a rigid load-bearing frame, combined with medical-grade sealing and environment-adaptive design, high-pressure inflatable medical tents realize the unification of ultra-fast deployment, high-strength load-bearing, all-weather protection and medical compliance, and have become the core emergency medical equipment for international disaster relief, plateau medical care and polar scientific research.
2 Product Structure and Technical Principles
2.1 High-Pressure Rigid Arched Air Column Structure
Taking the structurally optimized arched air column as the main load-bearing body with a working pressure of 500–1000 KPa, it forms a quasi-rigid truss system after inflation, which significantly improves the overall anti-tilting, wind load and snow load resistance capacity.
• The air column is made of high-strength composite airtight materials with the characteristics of high pressure resistance, tear resistance and weather resistance stability;
• Modular zoned air circuit design, local damage will not cause overall instability, ensuring continuous use;
• The outer tent and air column can be quickly disassembled and assembled, facilitating long-distance transportation, on-site maintenance, and long-term deployment.
2.2 Fully Sealed Medical Enclosure System
The main body of the tent adopts medical-grade airtight and flame-retardant composite fabrics with complete protective functions:
• Windproof, waterproof, snowproof, moistureproof, dustproof, and UV resistant, isolating external pollution and extreme climates;
• The overall airtightness meets the requirements of aseptic areas and high-altitude pressure maintaining, reducing the risk of cross-infection;
• Adapt to built-in HVAC air ducts and ventilation interfaces to achieve stable and controllable temperature, humidity and air exchange rate.
