Introduction

mmic™ has provided mobile medical units with protective environments for 25 years.  The following is a description of 3 products adapted from mmic’s™ commercial and military product platforms that can provide mobile, rapidly deploy-able assets for the assessment and containment of infectious diseases.  This specific effort is focused around Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) that has caused the COVID-19 infectious disease pandemic.  While the current focus is on COVID-19 these units are relevant to future response to other non-SARS based infectious disease events.

The three products cover three aspects of the spread of the disease:

1) Infectious Disease – Rapid Response Unit™ (ID-RRU™) – to respond to emerging hot spots of infection.

2) Infectious Disease -Mobile Testing Unit™ (ID-MTU™) – to conduct mobile verification testing and:

3) Infectious Disease Mobile Isolation Unit™ (ID-MIU™) for the isolation and care of patients with severe enough cases that they require hospitalization.

The ID-RRU™ is based on mmic’s™ rapidly deploy-able hybrid shelter system product platform and the ID-MTU™ & MIU™ are based on mmic’s™ commercial mobile medical unit platform.The ID-RRU™ is also a valuable asset for patient care surge space as needed to relieve capacity constraints caused by many other emergency needs.  The platforms and products are described below.

mmic™ Rapidly Deployable Shelter System Platform

mmic™ has significant experience in developing hybrid rapidly deploy-able medical shelter systems.  These systems that have both hard and soft shelter (tent) components were developed under the US Military’s Future Medical Shelter System (FMSS) program.  These ranged from 225 Ft² UTV tow-able unit for special operations medical units to a 2,250 Ft², 52 Bed, Emergency Triage Unit for the National Naval Medical Center contained in two tow-behind trailers capable of being towed by commercially available pickup trucks with the appropriate towing capacity.

These hybrid medical units are characterized being able to be rapidly deploy-able (set-up) and operational with minimal personnel.  This is due to mmic’s™ incorporation of inflatable composite structure (air beam) frames for the SWS’s (tents) into a hard-walled transport structure (i.e. trailer or ISO container).  The use of air beam tents allows lighting, power and HVAC distribution to remain in the tents, which eliminates the need for installing these essential utilities after the tent is set-up.  The air beam tents that mmic’s™ co-developed and have used are also self-erecting when inflated.  The transport structure contains an integrated generator and HVAC system that enhance the speed of deploy-ability and make them self-supporting.

Infectious Disease – Rapid Response Unit (ID- RRU)  

The following are pictures of a hybrid unit that provides 600 Ft² of rapidly deploy-able tent space integrated onto a 30 Ft. long commercial tow-behind trailer.  This system is fully self-contained with a 40kw generator that supplies power to the 600 Ft² tent, transport trailer with communications equipment and rooftop HVAC units for both.  The self-erecting air beam tent has integrated rugged LED lighting, power distribution and HVAC ducting.  The air beam tent also has side and end doors, and auxiliary HVAC supply and return ports for use as a stand-alone shelter if needed.

mmic™ Commercial Mobile Medical Unit Platform

mmic™ has a proprietary mobile medical unit platform based on a custom designed and constructed 53’ semi-trailer that is capable of expanding to nearly 1000 Ft².  This platform that has been developed and enhanced over 25 years is the basis of our two flagship products.  These are the Mobile Surgical and Mobile Sterilization Units (MSU™ & MSPS™) that are integrated with customized HVAC to provide US code compliant protected environments.  These units are designed per Facilities Guidelines Institute (FGI) – Guidelines for the Design and Construction of Hospitals and meet the appropriate life safety and governmental guidelines specified therein.  These products have been deployed at many private and governmental hospitals throughout the United States.  They have received Joint Commission certification as part of these deployments and they also meet CMS requirements.

Infectious Disease – Mobile Testing Unit (ID- MTU)  

The ID-MTU™ is based on mmic’s™ commercial Mobile Medical Unit (MMU) platform.  The unit provides mobile testing capacity for infectious diseases while protecting healthcare personnel.  This is done by providing physical as well as environmental systems that separate the patients of unknown infection status from pre-tested non-infected healthcare workers.  Two separate entry/exit points are used and once on board the clean healthcare personnel area is segregated and maintained as a positive pressure environment to the patient test area to eliminate exposure to infected patients.  This unit could accept screened patients from the ID-RRU as described above or be used stand alone.

 

Test Protocol – Once a test patient enters the “Test Patient Vestibule” (Airlock) there is a two-way communication (video and audio) with the healthcare personnel in the clean area.  Upon establishing communications and confirming a valid test request from appropriate healthcare personnel, the test patient would be allowed to enter the Patient Test Area via the remotely controlled access (electronically locked) door.  The test patient would be directed to one of the eight “Patient Test Rooms” and directed via two-way communications to take a sample.  Once complete the patient would place the test specimen in the “Test Specimen Pass Thru” for collection by healthcare personnel once they have exited the unit.

Soiled Material Handling – The Patient Test Area would be disinfected periodically.  Soiled material would be bagged, marked and placed in the “Soiled Handling Area” for collection and appropriate subsequent disposal (incineration).  There is also a clean work area and a pass through to the soiled holding area for any collection material in question.

It is estimated that 25 – 30 patients per hour could be tested with this unit with appropriate supplies and personnel.

Infectious Disease – Mobile Isolation Unit (ID- MIU)

The ID-MIU™ is based on mmic’s™ commercial Mobile Medical Unit (MMU) platform.  The unit is a mobile isolation ward for patients who have contracted the disease and whose condition has become severe enough to require hospitalization.  It allows hospitals to care for acute cases of SARS-CoV-2 without bringing them into the same facility as non-infected patients and healthcare personnel.   It provides a physically and environmentally separate area for healthcare personnel to observe the patients and don Personnel Protective Equipment when direct attendance is necessary.  This area is kept under positive pressure to the isolation area to eliminate any infiltration of air from the patient area.  The unit provides an access ramp for ambulatory patients and a vestibule (airlock) to keep the isolation area negative pressure.

Soiled Material Handling – Soiled material from the Patient Isolation Area would be bagged, marked and placed in the “Soiled Handling Area” for collection and appropriate, subsequent disposal (incineration).  There is also a work area and a pass through to the soiled holding area for any contaminated material.

Conclusion

From evaluation with the ID-RRU to testing with the ID-MTU to post infection care of acute cases with the ID-MIU, mmic’s™ Infectious Disease Product provide mobile, rapidly deploy-able assets that can be used to contain the spread of SARS-CoV-2 based infections.  These units are designed to protect healthcare workers while providing patients with effective care.  Their mobility is not limited to ground, both our commercial MMU and hybrid RDSS platforms are designed and certified to be air transportable.  This allows for rapid relocation of assets to outbreak hot spots as needed.
