CEILING FILTRATION SYSTEM FOR OPERATING THEATRES UNDER ISO CLASS 5 OPERATIONAL CONDITIONS A STERILE ENVIRONMENT FOR PATIENT SAFETY AND THE COMFORT OF THE SURGICAL TEAM
Our ceiling filtration systems are the result of thirty years’ experience in developing air filtration and distribution techniques for operating theatres.
Our ceiling filtration systems are the result of thirty years’ experience in developing air filtration and distribution techniques for operating theatres.
To protect patients from the risk of contracting nosocomial infections, especially those caught during surgery due to airborne micro-organisms, reducing the presence of contaminants throughout the entire surgical procedure is an absolute must, particularly in the critical zone occupied by the patient and in the area surgical instruments are kept in.
Since it is the very people working inside the operating theatre who are the main sources of contamination, as generators and releasers of biologically active particles, and it is impossible to remove them from the scenario, the terminal supplying the properly filtered air must be capable of removing all types of pollutants from the patient area as quickly and efficiently as possible.
For this exact reason, SagiCofim has designed and created a unique and non-conventional solution that enables even the most critical of surgical rooms to achieve outstanding internal air quality levels: this solution is called DIF-OT.
We are proud to have been able to transform a dream into an idea, and then that idea into a real solution.
Features
- Mechanical self-balancing function with 3 differential airflow speeds, decreasing from the ceiling centre outwards.
- For ISO Class 5 environments both under operating conditions, certified by ISO14644-1, and simulated conditions, certified by Swiss standard SWKI VA105-01:2015-08.
- Suitable for operating theatres with a concentration of Colony Forming Units under 10 CFU/m³ under operating conditions.
- Efficient contaminant-removal system due to the combined effect of the air speed and the air return grilles located in all four corners of the room.
- Guaranteed comfortable environment for the surgical team.
- Noise levels compliant with UNI standard11425.
- Stainless steel structure for maximum resistance to sterilising agents.
- System designed to ensure complete safety of use without the need for fixed perimeter air curtains.
- Flexible positioning of units
Advantages
- Guaranteed ISO Class 5 Operational
- The best choice for both new projects and refurbishments.
- Modular version available for different-sized and shaped spaces.
- No barriers and perimeter air curtains makes moving equipment around the room easier.
- Reduced energy consumption.
Applications
Its versatility is what makes the DIF-OT the ideal solution for any surgical theatre, including those with specific structural or architectural constraints, such as hybrid rooms with floor or ceiling-mounted X-ray machines, for example.
The integrated recirculation system version is also the ideal solution for refurbishments or updates to existing operating theatres.
Isolation rooms
Hospital departments identified as isolation rooms consist of wards for infectious and haematological diseases, but also isolation rooms for burn patients, transplant patients or the immunosuppressed.
To meet the performance level required for treating immunosuppressed patients, the use of a horizontal unidirectional flow is required.
With the different meanings, these types of departments must be structured in such a way as to guarantee maximum protection of these wards through strict control of both contact and airborne contamination, both for the protection of the patient and the medical staff providing their services.
IMMUNOSUPPRESSED WARDS
For immunosuppressed patients’ rooms, it is necessary to consider:
- high risk of infection due to contact and airborne pathogens.
- prolonged drug treatment in phases and with intravenous injection.
- treatment for patients can last several weeks.
For these reasons, the room pressure trend is obviously gradually increasing towards high-containment rooms.
The department is structured with differentiated room pressures and dedicated pathways for different users.
Recommended
- Positive pressure in the isolation single-bed rooms to preserve the patient
- Horizontal air flow, consisting of the entire head end of the bed, which first touches the patient and allows the medical staff to stay downstream of the patient at all times. In this configuration, the entire volume occupied by the patient is supplied with air filtered by HEPA H14 filters.
- All items to be used by the patient are passed through a pass-through hatch fitted with unidirectional airflow and germicide UV lamps to sterilise them
- System safety: specific and dedicated air handling units for each room, as well as unidirectional flows with HEPA-ULPA terminal filtration.
INFECTIOUS DISEASES WARDS
- a source of infected micro-organisms
- a susceptible host
- a means of transmission for the micro-organism.
Recommended
- Negative pressure in the isolation room to protect staff and operators
- Controlled and filtered exhaust of contaminated and infected air
- Air handling unit dedicated to each individual room, allows for complete sterilisation of the room and the system dedicated to it without interruption of continuity, guaranteeing the best environmental conditions of the hospital stay
- The access doors to each room must be equipped with access indicators.
