Introduction
A mobile operating room is not simply a clean room on wheels. It is a complex clinical environment where every technical detail determines the success of surgical interventions.
Whether for humanitarian missions, emergency situations, or hospital overcrowding relief, a well-designed mobile unit enables procedures ranging from appendectomies to orthopedic surgery, in complete safety.
Essential Medical Equipment
1. Mobile Operating Table
This is the heart of the operating room. It must allow precise patient positioning for all types of procedures.
Essential features:
- Weight capacity: Minimum 250 kg (550 lbs)
- Motorized movements:
- Trendelenburg: 25°
- Reverse Trendelenburg: 25°
- Lateral tilt: 15° left/right
- Horizontal slide: up to 35 cm (13.75 inches) for C-arm access
- Adjustable height: 70 to 100 cm (28-40 inches)
- Emergency battery: Continues operation during power failure
- Large casters: Easy movement between pre-op, OR, and recovery
2. Surgical Lighting (Surgical Light)
Perfect visibility is non-negotiable.
Specifications:
- Adjustable intensity (up to 160,000 lux)
- Color rendering index CRI > 95%
- Shadowless illumination
- Folding mechanism for transport
3. Anesthesia System
Equipment:
- Anesthesia machine with integrated ventilator
- Multi-parameter monitor (ECG, SpO2, NIBP, EtCO2, temperature)
- Emergency crash cart with defibrillator
- Infusion pumps
4. Intraoperative Imaging (Optional by Specialty)
For orthopedic, trauma, or vascular surgery:
Mobile C-arm:
- Power: 2.5 to 25 kW depending on model
- Detector: 21-30 cm, high-sensitivity CMOS technology
- Motorized mobility: Advanced models are self-guided
- Energy storage: Integrated battery for wireless use
- Clearance: 78-92 cm for comfortable working space
5. Sterilization
- Autoclave: Sterilize instruments on-site
- Pass-through window: Between dirty and clean zones
- Ultrasonic cleaner: For delicate instruments
6. Furniture and Complementary Equipment
- Rolling instrument tables
- IV poles
- Storage cabinets for consumables
- Refrigerator for temperature-sensitive medications
- Hands-free sinks
Standards and Regulations
ISO Classification
A mobile surgical unit must achieve at minimum ISO Class 5 for the operating area. This means:
- Laminar flow ceiling
- HEPA filtration at 99%
- Air exchange rates suitable for surgery
Positive Pressure
Unlike BSL laboratories (negative pressure), the operating room must maintain positive pressure relative to adjacent areas. Air flows out of the OR, nothing flows in. Microbes stay outside.
Electrical Standards
Per regulations (NFPA 99, NFPA 70):
- Hospital-grade grounding outlets
- Automatic emergency power transfer
- Generator with automatic transfer switch
- UPS for sensitive equipment
Vehicle Structure
Typical Dimensions
| Configuration | Length | Width (retracted) | Width (extended) | Height |
|---|---|---|---|---|
| Single van | ~8-9 m | 2.5 m | 3.7 m | ~3.9 m |
| Semi-trailer | ~12 m | 2.5 m | Up to 5 m | ~4 m |
| 20′ container | 6 m | 2.4 m | 3.5-4 m | 2.9 m |
| 40′ container | 12 m | 2.4 m | 3.5-4 m | 2.9 m |
Expansion
Most mobile units are expandable. Side walls slide out to double interior width once on-site. This provides:
- Comfortable operating space
- Distinct zones (preparation, surgery, recovery)
Weight
Complete unit: 13,000 to 13,500 kg depending on configuration.
Chassis
- 4×2 for most configurations
- 4×4 recommended for difficult terrain
Interior Organization: Essential Zones
A well-designed mobile surgical unit includes:
1. Reception and Preparation Area (Pre-Op)
- Patient intake space
- Medical records
- Preparation (IV, shaving, etc.)
2. Operating Room (Sterile Zone)
- Central operating table
- Surgical lights
- Anesthesia equipment
- Imaging equipment (if specified)
- Medical gas outlets (oxygen, vacuum, nitrous oxide)
3. Recovery Area (Post-Op)
- Beds or monitoring chairs
- Patient monitors
- Oxygen
4. Sterilization and Preparation Zone
- Autoclave
- Surgical scrub sink
- Sterile instrument storage
5. Staff Changing and Restrooms
- For personnel
- Decontamination shower (optional)
6. Technical Area
- Generator
- HVAC system
- Water and gas tanks
Technical Systems
HVAC and Air Treatment
This is the most critical system after sterilization. It must:
- Maintain stable temperature (19-24°C / 66-75°F)
- Control humidity (30-60%)
- Ensure HEPA filtration at 99%
- Operate in extreme temperatures: -20°C to +45°C (-4°F to +113°F)
Power and Autonomy
| Source | Role |
|---|---|
| Generator | Full autonomy in remote locations |
| Battery bank | Silent operation, emergency backup |
| Shore power | When grid connection is available |
Medical Gases
- Oxygen (cylinders or concentrator)
- Vacuum
- Nitrous oxide (optional)
- Medical air
Water
- Fresh water tank (for washing)
- Waste water tank
- UV sterilizer (optional)

Frequently Asked Questions
“How much does a mobile surgical unit cost?”
Price varies significantly based on size, equipment, and automation level. A basic unit with standard equipment is very different from a high-end OR with integrated 3D imaging. Contact us with your requirements for a proposal.
“What’s the difference from a simple converted container?”
A true mobile surgical unit meets ISO Class 5 standards, has HEPA filtration, redundant systems, and validated organization. It’s not simple conversion—it’s a certified operating room.
“Can it operate in extreme conditions?”
Yes. Our units are tested to operate from -20°C to +45°C, with reinforced insulation and adapted systems.
“How long can it operate autonomously?”
With generator and reserves, a unit can function for several days without external support. Actual duration depends on power consumption and installed equipment.
“Is special training required?”
We train your teams on all systems. A mobile unit differs from a fixed OR—proper familiarization is essential.
“Do you deliver to Africa?”
Yes. We deliver throughout Africa and handle all export logistics.
