UV-SAN - UltraViolet Sanitizing System designed for continuous sterilization of Emergency Medical Vehicles fleets and for real-time remote monitoring of sterilization level

Objectives of the service

The uncontrolled contamination of ambulances with pathogenic microbes poses a potential threat to public health (patients and healthcare operators) considering the many millions of ambulance operations that are made globally each year.

UV-San exploits the well-known germicidal power of ultraviolet light emitted in the UV-C wavelengths range to sterilize surfaces inside the patient’s compartment of  Ambulances that, coming into contact with the human body, are a persistent way for the transmission of viruses/bacteria.

UV-San is designed to be used several times a day after the transport of a patient, without the intervention of specialized operators and without the use of chemicals products. The ease of use allows to reduce significantly the downtime of ambulances with respect to standard sterilization procedures, increasing the usage time of ambulances.

The patented system for control of UVC radiation and ozone concentration ensures high level of safety to Health Operators and patients. In addition, GPS and SATCOM allow to keep a real-time and complete traceability of all the Sterilization Operations performed. These technical characteristics allow UV-San to offer two main features:

  • Continuous and Safe Sterilization of Ambulances, protecting healthcare operators, patients and hospitals from accidental contagion of pathogens, a problem worsened with the COVID-19 pandemic
  • Real Time Remote Monitoring of Sterilization Level, supporting the national health system and the community in facing the spread of COVID-19 and other pathogens

Users and their needs

UV-San is a sanitation system addressed to Hospitals, Providers of Patients Transport Service and Ambulance Manufacturers with the aim of ensuring an effective and rapid disinfection of ambulances after the transport of a patient (known, suspect or unknown COVID-19 patient).

Sanitizing ambulances is a time-consuming operation that can significantly reduce the availability of vehicles and the readiness for the timely treatment of COVID-19 patients. UV-San is designed to ensure an effective sanitation several times during a day, avoiding time-consuming sterilizations. Moreover, maintaining the geo-traceability of all the sanitations carried out, the system meets following needs of the targeted User Communities:

Patients Transport Service Providers:

  • Reduce the ambulances downtime due to standard sanitation operation
  • Provide a real-time traceability of sanitation performed and the sanitation level of the in service ambulances

Hospitals:

  • Reduce the risk of environment contamination and contagion of patients and healthcare operators related to the transport of known, suspect and unknown COVID-19 patients
  • Improve traceability of potential contacts improving readiness in identification of contagions chain

Ambulance Manufacturer:

  • Provide new sanitation tools already integrated into ambulances

The Pilot-User of the Project is “Università Campus Bio-Medico” that will validate UV-San in operational environment with the involvement of the “Heart Life Croce Amica”, Italian company providing ambulance service.

Service/ system concept

UV-San is a system designed for reducing the contagion risk coming from uncontrolled contamination of ambulances, providing an additional protection to Patients and Healthcare Operator and improving:

  • Sterilization level of Ambulances: the use of UV-San many times a day can limit the risks to have an ambulance as a potential means for diffusion of pathogens.
  • Situational Awareness: the real-time update of sterilization level of ambulances allows a more efficient management of vehicles fleet ensuring a healthcare service as safe as possible.

UV-San is composed by three main components :

  • Sanitizing Equipment (SE) is installed in the ambulance that can be activated by the User to sterilize the patient’s compartment. During the Sterilization Operation, it monitors the internal environmental condition, especially ozone concentration and UVC radiation, and transmits data to the Central Control System.
  • Central Control System (CCS) is installed in a control room and records all the operations performed by UVC-SE real-time monitoring and keeping traceability of sterilization level.
  • Web Application (WEB-APP) provides access to the data collected by the system and allows the authorized User to visualize historical and real-time data.

UV-San – System Concept

Space Added Value

The SAT-NAV and SAT-COM space technologies are the key-technologies enabling the Real-Time Remote Monitoring of Sanitizing Level of Emergency Medical Vehicles (EMV), allowing the geo-tracking of vehicles and the real-time transmission of data from any position.

UV-San integrates a positioning system that allows to record the time, position and during which path the sterilization operations were carried out, implementing a full geo-traceability of sterilization operations and sterilization level of each single EMV.

The historical data can be used for subsequent analysis to evaluate the spreading process of pathogens if related to the conditions of patients transported by ambulance and, in case, to activate more stringent control procedures whenever the sanitation level of vehicles had been insufficient. 

UV-San is equipped with satellite communication system used as backup in case:

  • A real-time transmission with a very high level of continuity must be guaranteed. In this case, whenever the mobile network is not available, satellite communication would be activated.
  • The EMV are usually used in remote areas with no mobile connection coverage. SAT-COM guarantees real-time and reliable communication during the entire duration of a working shift

Current Status

The Project has started at the beginning of August 2020 and it is currently in the design phase. The Baseline Design Review has been successfully held in October

Istituto Superiore di Sanita (ISS), the main centre for research, control and technical-scientific advice on public health in Italy, is the project partner in charge to validate in laboratory environment the sterilization procedure against the Sars-Cov-2 virus. The validation activity is started in October 2020.

The validation in operative environment will be performed by the “Università Campus Bio-Medico”, Pilot User of the Project.

The Critical Design Review is planned in December 2020
