Isolation & Containment Unit (AICU™)



The AMoHS AICU™ is the first rapidly deployable mobile facility that can be operated independently of existing hospitals to isolate and contain Ebola or other highly contagious or infected patients. It has been designed not only to address today’s diseases, but to handle and control potential future deadly airborne biologicals and pathogens.

AMoHS has designed our AICU™ to be in compliance with American licensing, certification and accreditation standards. We have direct experience in developing more than 100 separate surgical facilities over the last thirty years.

Many considerations contributed to the design and development of a safe and clinically correct environment.

Our units are mobile, self-contained and can be quickly deployed to address the need to fulfill a function that may not exist within the hospital, or that may be better addressed outside the hospital



Summary
  • Ultimate protection of patient, staff and community
  • State-of-the-art decontamination, HVAC filtration & patient flow systems
  • Safe and clinically sound environment
  • Self-contained with redundant backup systems
  • Telemedicine ready
  • No interior hospital space needed / free-standing
  • Temporary or permanent use
  • Purchase and lease options available

As an example, an isolation / ICU room is not simply an area where equipment is available for performing critical care functions in an isolated environment. The development of a safe and contained environment for the patient and the medical staff, requires addressing the critical features that support and create an isolated and appropriate containment facility.

The following describes the considerations taken into account, and the complex features and capabilities contained within the AICU™.

The HVAC system will filter the discharged air through several filters, to insure that the outgoing air is free of contaminants. Secondly, will also provide a very complex balance of incoming air to return or exhausted air, to create a negative pressure condition in the Patient Isolation Room. This creates a condition that provides air inflow, so that when a patient isolation room door is open, the air entering the room will prevent escaping contaminants, and will ensure the containment function of the room. In addition, several of the supporting areas of the facility require a negative pressure relationship to contain and prevent escape of contaminants to the outside of the facility. Thus, the HVAC system requires a balance of the entire unit to address all of these requirements.

Another clinical issue we addressed is the control of the flow of patients, supplies, instruments, contaminated waste and staff into and out of the AICU™. In order to minimize the risk of cross contamination or a failure in containment of the facility, it will be important to have a well-developed system of procedures based on good flow design.

Contaminated waste will initially be bagged at the source. It is bagged again in the soiled workroom and placed in the contaminated waste room, where it may be compacted, and as it is ejected from the contaminated storage room, it will be placed into a labeled exterior containment bag, that has never been inside the facility, for removal and incineration.

It is critical to have a supporting contaminated waste workroom that is separate, to avoid splashing or contaminating clean equipment or supplies with soiled items. It is also important that the contaminated waste be removed to a safe storage area and not left in the AICU™, or transported through a clean area.

Our design also contains the provision for treating all forms of waste water by injecting bleach and or other disinfecting agents into the onboard holding tanks, along with a system for safely discharging treated water into containment vessels.

The AICU™ incorporates a two-airlock system for entry and exit of the isolation facility.

These airlocks incorporate a lockout function that prevents opening both doors of the airlock room at the same time.

When entering the airlock for accessing the facility, the airlock room is also pressurized with additional air to insure that upon opening the door that connects to the work corridor, any air- flow will be into the work corridor, to prevent airborne contaminants from entering the airlock.

The procedure for exiting the facility using the exit airlock, is similar to the entry procedure but also provides the capability for a wash down function, utilizing a disinfecting shower that can be adjusted from a mist to a complete wash down.

The airlocks also incorporate a bleach bath to disinfect the shoes of the staff.

The entry airlock also contains a disinfecting wash down function, in case it is ever needed for exiting, and also as a redundant system to back up the exit airlock if it should fail.

Individual rooms can be sealed, and disinfected and/or decontaminated separately, or isolated from a full-facility decontamination.

This allows for selective treating of independent areas that might have been contaminated. This capability is especially important, in that different patients might be at different levels of contagion or exposure.
