Abstract

The present invention relates to a method and a device for an internal killing of bacteria and virus in low speed dental (angled) handpieces and turbines. The method is characterized in that the (angled) handpiece or the turbine is loosened from its socket, that a bacteria and virus killing liquid, and maybe a lubricating agent, contained in a manually operable container, from behind by an adapter in a metered amount and in one manoeuvre, with a propellant gas, is injected from the container and into the channel (channels) of the (angled) handpiece (turbine).

Description

501 ass 2 göres och/eller avlägsnas i samband med rengöring, desinfice- ring och Smörjning. 501 ass 2 is made and / or removed in connection with cleaning, disinfection and lubrication.

En autoklavering av hand-/vinkelstycken och turbiner mellan varje patient är möjlig att genomföra, vilket dock för- utsätter en komplett uppsättning instrument för varje patient.An autoclaving of hand / angle pieces and turbines between each patient is possible to carry out, which, however, presupposes a complete set of instruments for each patient.

Detta skulle innebära en mycket stor nyinvestering för varje tandläkarmottagning, liksom ett utbyte av befintliga instru- ment mot sådana som inte suger in föroreningar, om nu sådana instrument över huvud taget finnes och om deras tätningar i så fall har en tillräckligt intressant ekonomisk livslängd.This would mean a very large new investment for each dental clinic, as well as an exchange of existing instruments for those that do not absorb contaminants, if such instruments exist at all and if their seals in that case have a sufficiently interesting economic life.

Det i dag effektivaste sättet att rengöra och smörja vinkel- stycken är en omständlig procedur med flera handgrepp och/ eller specialhjälpmedel. Befintliga specialhjälpmedel kräver dock en investering i storleksordningen 10.000 - 40.000 kr.Today, the most effective way to clean and lubricate angle pieces is a cumbersome procedure with several handles and / or special aids. Existing special aids, however, require an investment in the order of SEK 10,000 - 40,000.

Något sätt att ekonomiskt, enkelt och effektivt rengöra kyl- vattenkanaler och/eller drivluftkanaler finns inte.There is no way to economically, easily and efficiently clean cooling water ducts and / or driving air ducts.

Huvudändamålet med föreliggande uppfinning är att åstad- komma en teknik som på ett enkelt sätt tillåter en snabb och effektiv eliminering av risken för överföring av smitta från en tandpatient till en annan.The main object of the present invention is to provide a technique which in a simple manner allows a rapid and effective elimination of the risk of transmission of infection from one dental patient to another.

Ett annat ändamål med uppfinningen är att oskadliggöra/ avlägsna föroreningar som sugits in i en kylvattenkanal i sam- band med hand-/vinkelstyckets avstängning.Another object of the invention is to neutralize / remove contaminants which have been sucked into a cooling water duct in connection with the closure of the handpiece / elbow.

Ytterligare ett ändamål med uppfinningen är att oskadlig- göra/avlägsna föroreningar som migrerat in i borrhuvudet utmed exv borraxeln.Another object of the invention is to neutralize / remove contaminants which have migrated into the drill head along, for example, the drill shaft.

Dessa ovan angivna ändamål uppnås genom att förfarandet och anordningen erhållit de i patentkraven angivna känne- tecknen.These objects stated above are achieved by the method and the device having obtained the characteristics stated in the claims.

Genom att lossa hand-/vinkelstycket eller turbinen från sitt fäste så friläggs vid hand-/vinkelstyckets eller turbinens bakre del den eller de kanaler som leder kylvätska och eventuellt tryckluft, varvid en adapter enkelt kan "pluggas in" för att, via en drivgas, föra en doserad mängd av den i en manuellt hanter- bar behållare upptagna bakterie- och virusdödande vätskan, 501 355 jämte ev. smörjmedel in i kanalen (kanalerna). Detta kan så- ledes ske utan användning av några fördyrande arrangemang annat än själva adaptern. Denna behövs för ett korrekt införan- de av vätskan/smörjmedlet i kanalen (kanalerna) i hand-l vin- kelstyckets eller turbinen.By detaching the handpiece / elbow or turbine from its bracket, the rear part of the handpiece / elbow or turbine which conducts coolant and possibly compressed air is exposed, whereby an adapter can easily be "plugged in" to, via a propellant, carry a dosed amount of the bactericidal and virus-killing liquid contained in a manually manageable container, 501 355 together with ev. lubricant into the channel (s). This can thus be done without the use of any more expensive arrangements other than the adapter itself. This is needed for a correct introduction of the liquid / lubricant into the duct (s) in the handpiece of the angle piece or turbine.

Genom att hålla behållaren med öppningen nedåt under insprutningen i hand-/vinkelstycket eller i turbinen så säker- ställes att all vätska i behållaren kommer till användning och att drivtrycket i behållaren räcker till för att med rätt tryck genomspola kanalen (kanalerna) i hand-/vinkelstycket eller i turbinen.By holding the container with the opening downwards during the injection in the hand / angle piece or in the turbine, it is ensured that all liquid in the container is used and that the driving pressure in the container is sufficient to flush the channel (s) in the hand / the angle piece or in the turbine.

En behållare i storleksordningen 300 - 500 ml är lätt att hantera och med hjälp av adaptern (som sitter lösbart fäst vid behållarens öppning) passa in vid hand-/vinkelstyckets eller turbinens baksida.A container in the order of 300 - 500 ml is easy to handle and with the help of the adapter (which is detachably attached to the opening of the container) fits in at the back of the handpiece / elbow or turbine.

Drivgasen utgörs företrädesvis av luft, vilket innebär att vid de tryck som här utnyttjas kommer ingen luft att ñnnas i flytande form, varför någon blandning med den bakterie- och virusdödande och eventuellt smörjande vätskan inte kommer att ske. Vid exv propan som drivgas förekommer denna bland- ning, varför ett icke önskat utsläpp av drivmedel sker vid ut- sprutning. Detta frisläppande av drivgas i omgivningen, bidrar även till den s.k. växthuseffekten.The propellant gas is preferably air, which means that at the pressures used here no air will be formed in liquid form, so that no mixing with the bactericidal and virus-killing and possibly lubricating liquid will take place. In the case of propane as a propellant, for example, this mixture occurs, which is why an undesired emission of fuel occurs during spraying. This release of propellant gas in the environment, also contributes to the so-called the greenhouse effect.

Genom att använda luft som drivgas sker ingen fasom- vandling och ett ursprugstryck på exempelvis 8 bar vid en med vätska halvfylld behållare ger ett sluttryck på 4 bar när behåll- aren är tom på vätska.By using air as propellant, no phase conversion takes place and an original pressure of, for example, 8 bar at a container half-filled with liquid gives a final pressure of 4 bar when the container is empty of liquid.
