Relyon plasma will present new trends and developments in the field of atmospheric plasma applications in medical technology at MedtecLive, presenting how cold atmospheric pressure plasma can be used.
The most important characteristic of plasma for medical technology is its sterilising and disinfecting effect. Cold atmospheric pressure plasma can be used to sterilise medical devices and equipment easily, quickly and without the use of additional chemicals. PDD technology has made it possible to effectively neutralise the methicillin-resistant Staphylococcus aureus (MRSA), which is classified as particularly critical, without the use of antibiotics.
Functionalisation of implants in dentistry
Medical engineering materials such as zirconia ceramics or titanium and stainless steel, but also PEEK, Teflon, silicone and highly filled polymers can be effectively optimised in their wetting behaviour. This property is the basis for a good adhesive bond or biocompatibility and acceptance by the surrounding living tissue. This technology has already been used for many years in order to functionalise implants in dentistry. By functionalising the surfaces with atmospheric pressure plasma, the surface is cleaned, the implant sterilised and the risk of infection reduced. At the same time, the surface energy of the implant is increased. The improved wettability improves cell deposition on the surface of the implant and accelerates the healing process.
Ionisation module for germ and odour reduction in equipment
A further property of plasma is its germ and odour-reducing effect. In order to make this advantage individually usable, relyon plasma has developed a special ionisation module that can be integrated into a wide variety of equipment such as waste collectors or cabinet systems. A practical example is the Hailo ProfiLine Fresh L waste collector, which was developed in close cooperation with Hailo especially for clinical requirements. The ionisation module is integrated into the lid and automatically releases active oxygen, which then neutralises up to 99% of odours and moulds through the principle of electrical discharge.
Another approach for the use of plasma technology in the medical field is the dermatological treatment of wounds, skin diseases or infections. The cold plasma at atmospheric pressure acts in a complex way: via UV rays, reactive compounds and electric fields. The interaction of these factors significantly slows down the growth of bacteria, which accelerates healing.
