Hospital Mobile Toilet

The common type of mobile toilet used in hospitals is the modular temporary restroom, an emergency sanitation unit that integrates rapid deployment, hygiene safety, and environmentally friendly waste treatment functions. Its core features and classifications are as follows:

I. Structural and Functional Design
The modular temporary restroom is constructed with a metal or high-strength plastic frame, equipped with removable partitions, a water storage tank, an electric/foot-operated flushing system, and a sewage pipe interface. To reduce the risk of cross-infection, most are equipped with ventilation fans and ultraviolet disinfection lamps, and the top exhaust duct is fitted with a high-efficiency particulate air (HEPA) filter to intercept virus particles. The interior space is designed according to ergonomic standards: the toilet cubicle size is no less than 1.2 meters × 1.2 meters, featuring anti-misoperation door locks and emergency call buttons, with explosion-proof LED lighting and slip-resistant, corrosion-resistant flooring. For the needs of special populations, some are equipped with handrails, low-position washbasins, and widened doorways.

II. Scenario-Based Classifications

1. Integrated Modular Restroom
   Suitable for large-scale modular hospitals, it is transported as a whole by lifting. It is internally divided into male and female toilet cubicles and accessible toilet cubicles, equipped with independent washbasins and ventilation ducts, enabling rapid construction of standardized sanitation facilities.
2. Mobile Trailer-Mounted Restroom
   Designed with a wheeled chassis, it can be towed by a vehicle and is commonly found in post-disaster resettlement sites or wilderness camps. It has a compact interior space but complete functions, integrating power supply, water supply, and sewage systems to meet the needs of non-fixed locations.
3. Simple Assembled Restroom
   Designed for short-term emergency needs, it is quickly assembled from lightweight partitions. It usually lacks a flushing function and uses packing bags or biodegradation technology for waste treatment, suitable for scenarios with limited resources.

III. Sewage and Disinfection Systems
To block fecal-oral transmission, dual technologies are employed:

• Vacuum Negative Pressure Collection System: Excreta is instantly sucked into a sealed storage tank through negative pressure, reducing the risk of aerosol dispersion.
• Chemical Reagent Treatment System: Chlorine-based disinfectants or microbial degradation agents are added to the storage tank for in-situ disinfection of excreta.
  Daily maintenance must strictly adhere to emergency management standards: surface disinfection every 4 hours (using chlorine-based wipes), daily emptying of the sewage tank and replacement of disinfectant. In high-density usage scenarios, cleaning staff must wear protective gear and implement a "one toilet, one disinfection" policy, focusing on wiping high-contact areas such as toilet seats and door handles, while ensuring the ventilation system operates 24 hours a day.
