VALVES FOR USE IN MEDICAL VENTILATORS PRODUCTS, TECHNOLOGIES AND SERVICES TO HELP IN THE FIGHT AGAINST COVID-19


FASTENERS FOR VITAL MEDICAL EQUIPMENT


Ideally suited to controlling the airflow in ventilators, The Lee Company’s genvi is a versatile 3-port solenoid valve which offers the combination of high flow rates, low leakage and low power consumption in a miniature 10mm package. According to the company, this represents a range of valves which provides outstanding application versatility and unmatched reliability at an economical price point. One of the key objectives in developing the genvi


solenoid valve was to challenge the limitations of current fluidic technologies by allowing designers to use a miniature, low power solenoid valve, without compromising system-level flow rate requirements. As a result, the valve is capable of achieving


minimum flow rates of 30 to 40 SLPM at 15 psid and its spike and hold profile results in ultra-low power consumption (318mW) during continuous duty operation on air and compatible gas applications. Crucially, this reduces system-level heating and improves battery life, making it ideal for applications with challenging power budgets.


Bollhoff fasteners are used extensively in the manufacture of hospital trolleys, beds and trays, all of which are in significant demand as the Government strives to establish new field hospitals across the UK. The management at Bollhoff have


genvi is a compact 3-port solenoid valve which offers the


combination of high flow rates, low leakage and low power consumption


In addition to high flow, low power


consumption, minimal leakage and extended life of at least 25 million cycles, genvi valves are designed to provide response times of less than 10ms in applications with an operating temperature range from 40˚F to 120˚F. Typical applications for the valves include


molecular diagnostics, oxygen delivery, environmental monitors, compression therapy, breath analysers or wherever high flow and low power cannot be sacrificed for size and reliability. In addition to the genvi valve, the company’s


HDI solenoid valves are being used in ventilators for the auto zero function of the pressure transducers; and its IMH relief valves are also suitable for use in some ventilators.

DROPLET PROTECTION SCREEN HELPS TO PROTECT STAFF


RK Rose+Krieger (part of the international Phoenix Mecano group of companies) has developed a droplet protection system that is designed to protect staff. Based around a 700 x


800mm plastic panel, the design is not only flexible (as can be seen in the images) but is


also simple to set up, quick to assemble and easy to clean. The screen can be used in numerous areas of application – from


point of sale in open-plan offices and reception areas, to hospitals, pharmacies, clinics, grocers, market stalls, shops, reception areas, banks, offices and much more.

taken steps to ensure that they can provide continuity of supply to the manufacturers concerned. The company’s Rivnut, Amtec and Snaploc fasteners, used for speedy and secure fastening into the aluminium sheet and section used in trolleys, beds and trays, are in particularly high demand. Bollhoff industry manager, Clive


Brown, said: “Our colleagues at plants in Willenhall and Germany, as well as the team here in Hull (producing Helicoil threaded inserts) are working flat-out to ensure that demand is met for this vital equipment. We all wanted to see the new hospitals operational in double quick time, and we remain indebted to our own suppliers and their staff for keeping us supplied with the essential materials we need to make the fasteners.”
