Полезная модель относится к области упаковки для стерилизации изделий, в частности, медицинского назначения различными способами (паровая, газовая, радиационная, воздушная и т.д.). Упаковка для стерилизации изделий выполнена в виде прямоугольного конверта, изготовленного из двух слоев, причем один слой выполнен из листа термостойкого материала, а второй слой представляет собой лист водостойкого бумажного материала, с образованием по периметру с трех сторон сварных швов и открытого устья. Открытое устье может быть снабжено закрывающим клапаном с двухсторонней липкой лентой, закрытой слоем антиадгезивной бумаги. Упаковка дополнительно содержит средство удержания индикатора, выполненное в виде кармана, конструктивно отделенного от стерильной зоны посредством сварного шва и расположенного в боковой верхней части упаковки в зоне открытого устья. Полезная модель позволяет исключить возможность загрязнения или негативного влияния компонентов индикатора на стерилизуемое изделие. 1ил.

Номер: RU0000201570U1
Автор: Руслан Григорьевич Котченко
Принадлежит: Руслан Григорьевич Котченко

Индикатор контроля стерилизации, содержащий стойкую к условиям стерилизации основу, на лицевую сторону которой нанесены эталонная метка и индикаторная метка. Индикаторная метка представляет собой зональное покрытие, выполненное с применением термочувствительной композиции, необратимо меняющей свой цвет после цикла стерилизации. Обратная сторона основы покрыта адгезивным слоем и защитным антиадгезивным покрытием, предназначенным для предохранения адгезивного слоя индикатора вплоть до его закрепления на контролируемом объекте. От прототипа отличается тем, что зональное покрытие дополнительно содержит споры тест-микроорганизмов, фиксация которых осуществлена с применением упомянутой термочувствительной композиции. Фиксация спор тест-микроорганизмов может быть осуществлена двумя способами:- споры тест-микроорганизмов нанесены на подложку и зафиксированы покрывающим слоем, сформированным из термочувствительной композиции индикаторной метки. То есть, индикаторная метка выполнена двухслойной;- споры тест-микроорганизмов включены в состав термочувствительной композиции и участвуют в формировании индикаторной метки.

Method and system for inspecting the inside of a small channel, e.g. a flexible tube or hose, particularly for medical use, e.g. included in an endoscope, for the presence of inside contaminations on the wall of the tube, comprising providing the inside of the channel with a liquid having a refractive index which is higher than the refractive index of the channel wall, transmitting a signal into one end of the channel having a wavelength w, comparing the spectrum of the signal received at the other end of the channel with the wavelength w of the transmitted signal and determining, e.g. by a spectrum analyzer, whether the latter signal contains any wavelength w′ which is unequal to the wavelength w of the transmitted signal, and indicating that, when not any wavelength w′ is determined unequal to w, the channel is not contaminated or that, when any wavelength w′ is determined unequal to w, the channel is contaminated. The system may include means for cleaning the inside of the channel by means of said liquid having a refractive index which can be higher than the refractive index of the channel wall which thus is used both as cleaning liquid and as light conducting core.

Polyethylene cross-linked with an anthocyanin

Номер: US20120187607A1
Автор: Aiguo Wang, Daniel E. Lawrynowicz, Shi-Shen Yau, Shulin He
Принадлежит: Howmedica Osteonics Corp

A method for manufacturing of ultrahigh molecular weight polyethylene (UHMWPE) for implants, where the implants have been machined out of UHMWPE blocks or extruded rods, has anthocyanin dispersely imbedded in the polyethylene. The implant is then exposed to γ ray or electron beam irradiation in an amount of at least 2.5 Mrad followed by a heat treatment to prevent the implant from becoming brittle in the long term as well as to improve strength and wear. The method includes mixing a powder or granulate resin of UHMWPE with an aqueous liquid that contains anthocyanin in a predetermined amount. The water is evaporated in order to deposit the anthocyanin in a predetermined concentration on the polyethylene particles. The doped UHMWPE particles are compressed into blocks at temperatures in a range of approximately 135° C.-250° C. and pressures in a range of approximately 2-70 MPa. Medical implants are made from the blocks.

The method of removing Escherichia coli ( E. coli ) bacteria from an aqueous solution includes the step of mixing multi-walled carbon nanotubes into an aqueous solution containing E. coli bacteria. The multi-walled carbon nanotubes have an antimicrobial effect against the E. coli bacteria. The multi-walled carbon nanotubes may be mixed into the aqueous solution at a concentration of approximately 0.002 g of multi-walled carbon nanotubes per 100 ml of the aqueous solution. In order to enhance antimicrobial activity, the multi-walled carbon nanotubes in the solution may be treated with microwave radiation, thus generating heat to further destroy the bacteria. In order to further enhance antimicrobial activity, the multi-walled carbon nanotubes may be functionalized with a carboxylic (COOH) group, functionalized with a phenol (C 5 H 5 OH) group, functionalized with a C18 group, such as 1-octadecanol (C 18 H 38 O), or may be impregnated with silver nanoparticles.

Sterilization system with ultraviolet emitter for eradicating biological contaminants

Номер: US20120223216A1
Автор: Bruce L. Winkler, Patrick Flaherty, Robert J. Gold
Принадлежит: Teckni Corp

An exemplary sterilization system includes a self-propelled robotic mobile platform for locating and eradicating infectious bacterial and virus strains on floors (and objects thereon), walls, cabinets, angled structures, etc., using one or more ultraviolet light sources. A controller allows the system to adjust the quantity of ultraviolet light received by a surface by, for example, changing the intensity of energy input to a ultraviolet light source, changing a distance between a ultraviolet light source and a surface being irradiated, changing the speed/movement of the mobile platform to affect time of exposure, and/or by returning to contaminated areas for additional passes. The mobile platform may include a sensor capable of detecting fluorescence of biological contaminants irradiated with ultraviolet light to locate contaminated areas. The system is thus capable of “seek and destroy” functionality by navigating towards contaminated areas and irradiating those areas with ultraviolet light accordingly.

Disclosed is a method of sterilizing an article by sequentially exposing the article under vacuum first to a gaseous conditioning agent for forming radicals and then to a sterilant. The preferred conditioning agent is hydrogen peroxide and the preferred sterilant is ozone. The chamber is initially evacuated to a first vacuum pressure and then sealed for the remainder of the sterilization process and during all sterilant injection cycles, without removal of any component of the sterilization atmosphere, which means without any measures to reduce the water vapor content. Keeping the chamber sealed and maintaining the conditioning agent and the radicals generated thereby in the chamber for the sterilization with sterilant results in a synergistic increase in the sterilization efficiency and allows for the use of much lower sterilant amounts and sterilization cycle times than would be expected from using the conditioning agent and the sterilant in combination. 1. A method for sterilizing an article in a sealable sterilization chamber , comprising the steps ofa. placing the article into the sterilization chamber,b. sealing the chamber,c. applying to the chamber a vacuum of a first pressure,d. injecting into the sealed chamber a gaseous conditioning agent for forming free radicals,e. maintaining the chamber sealed for a first exposure period,f. injecting, after the first exposure period, a sterilant gas for creating or regenerating the free radicals into the sealed chamber,g. maintaining the chamber sealed for a second exposure period,h. removing residual sterilant from the chamber at the end of the second exposure period, andi. removing the sterilized article from the chamber.2.
