Abstract

The development of a dielectric barrier discharge (DBD) sterilizer for cleaning, disinfection, and low-temperature sterilization in water saturated with ozone is described. The sterilizer consists of an ozone generator based on glow barrier dielectric discharge with flat electrodes covered with dielectric operated at a high-voltage power supply of 250 W. The 2.5-L sterilization bath is equipped with a 100-W ultrasound source to provide additional cleaning of complexly shaped objects. High ozone concentrations in water (up to 10 mg/L) are necessary for effective and complete sterilization of tools and is achieved by dissolving ozone in cooled water (∼ 10–15°C). The ozone concentration at the output of the ozone generator is 25 mg/L. The main characteristics of the ozone sterilizer with ultrasonic cavitation are given, and the effectiveness of this sterilizer in inactivating a number of microbiological objects is shown.

用于医疗器械低温处理的多功能超声空化DBD臭氧消毒器

介绍了一种介质阻挡放电(DBD)消毒器的研制，该消毒器可在饱和臭氧水中进行清洗、消毒和低温灭菌。该灭菌器由一个基于辉光阻挡介质放电的臭氧发生器组成，该发生器在250w高压电源下工作，其平面电极上覆盖着介质。2.5 l灭菌浴配有100 w超声源，可对形状复杂的物体进行额外清洗。水中的高臭氧浓度(高达10毫克/升)是有效和完全消毒工具所必需的，可以通过将臭氧溶解在冷水(~ 10 - 15°C)中来实现。臭氧发生器输出的臭氧浓度为25mg /L。介绍了超声空化臭氧消毒器的主要特点，并说明了该消毒器对多种微生物的灭活效果。

期刊介绍： Technology has always played an important role in medicine and there are many journals today devoted to medical applications of ionizing radiation, lasers, ultrasound, magnetic resonance and others. Plasma technology is a relative newcomer to the field of medicine. Experimental work conducted at several major universities, research centers and companies around the world over the recent decade demonstrates that plasma can be used in variety of medical applications. It is already widely used surgeries and endoscopic procedures. It has been shown to control properties of cellular and tissue matrices, including biocompatibility of various substrates. Non-thermal plasma has been demonstrated to deactivate dangerous pathogens and to stop bleeding without damaging healthy tissue. It can be used to promote wound healing and to treat cancer. Understanding of various mechanisms by which plasma can interact with living systems, including effects of reactive oxygen species, reactive nitrogen species and charges, has begun to emerge recently. The aim of the Plasma Medicine journal will be to provide a forum where the above topics as well as topics closely related to them can be presented and discussed. Existing journals on plasma science and technology are aimed for audiences with primarily engineering and science background. The field of Plasma Medicine, on the other hand, is highly interdisciplinary. Some of prospective readers and contributors of the Plasma Medicine journal are expected to have background in medicine and biology. Others might be more familiar with plasma science. The goal of the proposed Plasma Medicine journal is to bridge the gap between audiences with such different backgrounds, without sacrificing the quality of the papers be their emphasis on medicine, biology or plasma science and technology.
