Embodiment Construction

[0031] figure 1 A disinfection device using gaseous plasma according to the invention is schematically shown. The device includes a conduit 1 for introducing a nitrogen flow, and the nitrogen flow passes through a closed cavity (disclosure) that is in a vacuum state and is subjected to an electric field generator, wherein the electric field generator is composed of a generator 3 that emits 2.45GHz microwaves, and its power Regulated by the control device 5. Discharge gases generated by the thus generated plasma (in a known manner) are introduced into the treatment chamber 7 via a conduit 9 . The processing chamber 7 is placed in the post-discharge area of ​​the plasma and communicated with a vacuum pump 11 . A vacuum pump 11 draws out the discharged gas in the processing chamber 7 and ensures that the gas is discharged to the outside through a conduit 13 provided with a suitable filter 15 .

[0032] The processing chamber 7 includes a metal object holder 17 for holding an o...

Abstract

The invention relates to a device which is used for the sterilisation of objects (19), in particular medical or surgical instruments. The inventive device is of the type that can create a gaseous plasma from a gas flow which is subjected to en electric field. According to the invention, the resulting post-discharge flow is brought into contact with the surface of the objects to be treated. The device is characterised in that the gas flow comprises exclusively nitrogen. Moreover, the device comprises means for heating the aforementioned objects, which can heat said objects to a temperature of at least 60 < DEG >C during treatment. The invention also relates to a method of using the device.

Description

technical field [0001] The present invention relates to a disinfection device, in particular for medical or surgical instruments or apparatuses. The invention also relates to a method of using the disinfection device. Background technique [0002] In the medical field, sterilization is usually carried out using an autoclave, in which the instruments to be sterilized are heated to a set high temperature of up to 120 ° C and held for a set temperature in accordance with the operating procedures prescribed by law. time. First of all, please note that autoclaves are limited to sterilizing small volume items and cannot be used to sterilize tubing for devices such as dialyzers or dental equipment. Furthermore, the application of temperatures above 100°C to modern surgical instruments or instruments poses many limitations and obstacles, especially for sterilized fragile items and accessories, which contain parts made of synthetic polymer materials, while Synthetic polymeric mate...
