Abstract
Aiming at the scenarios of large-scale field medical rescue, high-altitude support, disaster emergency and military medical service, this paper systematically expounds the structural principle, core performance, customization system, engineering details and application value of the high-pressure main cabin + low-pressure corridor modular inflatable field hospital tent. With 500–1000 KPa high-pressure rigid air columns bearing the core medical functional areas and lightweight low-pressure inflatable corridors realizing module interconnection, this equipment balances extreme environment stability, rapid deployment and clinical environment compliance. It can quickly build a large-scale mobile hospital integrating surgery, ICU, triage, hospitalization, pharmacy, etc., meeting the needs of continuous medical operation under extreme conditions such as -45℃~70℃, 5000m altitude, Grade 10 strong wind and heavy snow.

1 Introduction
Most traditional field medical tents adopt a single frame or low-pressure inflatable structure, which have shortcomings such as insufficient structural rigidity, poor airtightness, chaotic functional zoning and limited expansion under extreme scenarios such as strong wind, heavy snow and high altitude. The high-low pressure hybrid modular field hospital tent adopts an innovative configuration of high-pressure main cabin load-bearing + low-pressure corridor connection, combining high-strength rigid structure with lightweight flexible channels to realize the unification of stability and reliability, rapid construction, seamless expansion and clinical compliance, and has become the core equipment system for international humanitarian relief, disaster emergency, plateau medical care and military medical service.
2 System Architecture and Working Principle
2.1 High-Low Pressure Hybrid Configuration Design
High-Pressure Main Medical Unit
• Working pressure: 500–1000 KPa arched air column frame, forming a quasi-rigid load-bearing structure
• Functional positioning: core medical cabins such as operating area, ICU, critical care disposal and aseptic treatment
• Core advantages: wind resistance ≥Grade 10, snow load ≥30kg/㎡, stable structure in extreme environments
Low-Pressure Connecting Corridor
• Structural form: lightweight low-pressure inflatable corridor
• Functional positioning: personnel circulation, material transfer, clean and sewage diversion, module interconnection
• Core advantages: light weight, rapid construction, flexible layout, no occupation of core medical space
2.2 Modular Interconnection Mechanism
• Adopt seamless docking interface to realize rapid airtight connection between high-pressure main cabin and low-pressure corridor;
• Support free combination of 2–10+ high-pressure main cabins, and expand into a complete hospital system on demand;
• Internal airtight partitions to realize clean and sewage zoning, doctor-patient diversion and infection control.
