Aussie ICU innovation
The Testo 550s and Testo 557s are smart digital manifolds with Bluetooth and two-way or four-way valve block. They feature a large graphic display, showing the measurement data and evaluation of the results. The new digital manifolds also come in multi-purpose kits.
The McMonty Medihood is a specialist ventilation system designed and developed by the head of mechanical engineering at Melbourne University, Professor Jason Monty, in collaboration with Dr Forbes McGain from Western Health, and Westaflex.
Guided menus accompany the measurement and allow the automatic recording of parameters. According to Testo, Bluetooth probes can be wirelessly and automatically connected to the instrument with a range of up to 150m.
Primarily designed for containment of large droplets, the McMonty Medihood can be assembled and mounted over a patient and is typically used in the ICU ward of a hospital.
The Testo 550i is a compact, digital manifold designed to be controlled by a smartphone or tablet. It communicates wirelessly and automatically via Bluetooth 5.0 with the wireless Testo Smart Probes for temperature, pressure and humidity, and calculates parameters automatically in the Testo Smart App. The Testo 552i is an app-controlled wireless vacuum probe. Testo says the vacuum is measured wirelessly (without hoses) via just one service port, without any loss of refrigerant. The probe also communicates via Bluetooth with the Testo Smart App.

The ventilation unit has a fan located on the back that pulls air over the patient and away from the caregiver. The air is then released through a HEPA H13 filter, designed to clean and scrub the air of smaller droplets of the virus. “Healthcare workers are able to treat and monitor patients with minimal restrictions, as it provides peace of mind with the added layer of protection,” says Medihood.

“It is also easy to remove should the patient require immediate clinical intervention.” The product is distributed by Westaflex Australia.

Road to recovery
Global clean air solutions manufacturer Camfil offers a complete range of in-room air cleaners designed to improve indoor air quality through the removal of ultrafine airborne particles, specific odours and hazardous gases.
Numerous studies have shown that increased outdoor ventilation rates improve our health and productivity while reducing the transmission of germs such as airborne virus and bacteria. Due to compliance issues, however, HVAC system designers face limitations increasing the rates, says Armcor Air Solutions.

“Every time we double the outdoor ventilation rate, we reduce the concentration and therefore the transmission rate of all indoor contaminants by 40 to 50 per cent,” says the company.

“If the mandatory 10L/s per person of fresh air costs $30 per annum, doubling this will consequently become $60 per person. But if energy recovery was installed, it is possible to introduce 20L/s per person for a cost of $18 per annum.”
Camfil air cleaners are designed for use within communal shared spaces, commercial offices, hotel rooms, hospital suites, warehouses, server rooms, cleanrooms and food production facilities. Go to: www.camfil.com.au or www.airepure.com.au ■

Available through Camfil Airepure, air cleaner configurations include particulate filtration using Camfil Absolute HEPA filters or E11-rated filters and molecular filtration using activated carbon or custom gaseous filtration options. Camfil’s CC 6000 ProSafe model conforms to BRCGS standards for food safety to help food and pharmaceutical processing facilities comply with stringent industry standards on safety, traceability and control.
“But the cost of introducing fresh air has usually meant that we have designed HVAC systems with the minimum outdoor air to comply with the standards.” The answer to this conundrum, Armcor says, lies in energy recovery.

Magnehelic marvel
According to air conditioning system supplier Complete Air Supply (CAS), the product includes non-toxic products that are anti-bacterial, anti-fungal as well as anti-viral. It is available in 5L and 15L containers.
The Series AT-605 is an ATEX/IECEx-approved magnehelic differential pressure indicating transmitter from Dwyer Instruments. The unit provides for both visual monitoring and electronic control of very low differential pressures in hazardous locations.
“These products create a barrier, which provides a protective layer on any surface,” says Complete Air Supply.
The dial gauge is supported by the two-wire, 4–20mA control signal, utilising the Dwyer magnehelic gauge mechanical design and Series 600 transmitter technology. The two-wire design simplifies any 4–20mA control loop powered by a 10–35VDC supply.
