Definitions
- the present invention refers to a method for complete clean- ing of different types of instruments, which are used within dental care and surgery, and where the purpose is to inter ⁇ rupt the infection chain.
- the handpieces and contra-angle handpieces which are used within dental care and surgery as carriers for different types of drills, cutters and smoothing discs etcetera however in their internal air-powered turbines have i.a. rubber details and temperature sensitive metal alloys, which will be negatively influenced at repeated and tedious exposure to the high temperature which is used, whereby the service life will be reduced to about 250 autoclaving cycles, which is an unacceptable low level in view of the fact that the high-tech instruments concerned are rather expensive.
- the in ⁇ struments At the end of the autoclaving process the in ⁇ struments have substantially the temperature, at which the autoclaving is carried out, i.e. commonly about 135°C, which means that the instruments must have time to get cooler or cool off before they are can be used again, which may take about 20 minutes.
- the purpose of the present invention is to provide a method by means of which it is obtain a uniform process, which allows that the infection chain is interrupted, and this has been obtained by means of the features defined in the accom ⁇ panying claim 1.
- one instrument or a small group of instruments, to be treated is first posi ⁇ tioned in a treatment chamber, which preferably may be one of several to a central unit connected and by the central unit serviced treatment chambers.
- these instruments can be both such, which are made in one piece, such as endoscopes within surgery and within dental care, e.g. lancets and tweezers, tongs, etcetera, and handpieces and contra-angle handpieces having internal channels, which incorporate delicate gaskets and rotatable elements, such as air turbine wheels.
- the instrument in this case consists of a contra-angle handpiece, which is provided with a internal rotatable elements, i.e. air turbine wheel, these rotatable parts are braked, in the most simple case in that their rotation is prevented completely, or in that they are prevented from rotating freely under influence of different treatment media, thus that these media will get a mechanical treatment effect against the rotatable parts.
- a contra-angle handpiece which is provided with a internal rotatable elements, i.e. air turbine wheel
- these rotatable parts are braked, in the most simple case in that their rotation is prevented completely, or in that they are prevented from rotating freely under influence of different treatment media, thus that these media will get a mechanical treatment effect against the rotatable parts.
- a drainage opening present in the upper part of the chamber is opened, at the same time as a washing medium, preferably water with detergent added, is introduced in the treatment chamber and at one hand is caused to flow through the hollow interior of the contra-angle handpiece and on the other hand is sprayed onto its outer side. After filling of this dish ⁇ water thus that the entire contra-angle handpiece is below the surface ultra-sound is applied, and this ultra-sound aided cleaning sequence is allowed to last for about 1 minute.
- a washing medium preferably water with detergent added
- the contra-angle handpiece thus cleaned is thereupon rinsed with fresh water, internally as well as externally.
- the rinsing water is drained directly and by applying a vacuum all water is removed, preferably also together with the air, which eliminates the risk for air pockets, which can prevent the subsequent treatment from effectively reaching all parts of the instrument, and particularly its hollow portions.
- the pressure in the chamber is lowered by means of vacuum to about 20 millibar.
- the contra-angle handpiece is brought to resume a temperature appropriate for use, by means of active cooling, which preferably can be effected in that a gas, such as air is allowed to expand under flow through the chamber and the contra-angle handpiece.
- active cooling which preferably can be effected in that a gas, such as air is allowed to expand under flow through the chamber and the contra-angle handpiece.
- An appropriate temperature is about 35°C.
