Definitions

  • the present invention relates to a method and a device for cleaning, disinfecting, rinsing and drying objects or instruments, in particular of metal or synthetic material.
  • Devices for cleaning objects or instruments are known by ultrasound using known detergent solutions which are not entirely satisfactory, in particular for cleaning dental instruments which may have traces of dental cements.
  • objects or instruments is meant here more particularly the small dental instruments, such as strawberries, grindstones, wicks, nerve pulls, etc., and in general all small elongated objects whose diameters are between about 0.5 and 5 mm and whose length varies from about 5 to 60 mm.
  • the invention is not limited to dental instruments, and it can very well be applied to surgical instruments, as well as timepieces, goldsmithery, small mechanical precision, etc., the dimensions of which may be included in the above-mentioned field or greater, and the shape of which may or may not be lengthened.
  • All these instruments can be made of different materials, such as ordinary or stainless steels, natural or synthetic diamond and carbides, metals except reactive metals such as Al, Be, Mg, Zn and other metals reactive with alcohols, plastics except polystyrene, ethyl -cellulose and polyvinyl alcohol, elastomers, etc.
  • the object of this invention is to provide a method, and a device for the implementation thereof, allowing to make ready for a new use objects or instruments such as those mentioned above by way of example. employed and newly employed. This implies, in the case of dental instruments, in particular removal by washing of blood, saliva, food and dental debris, treatment products, medicines, cements and other soiling, etc., as well as the disinfection of these instruments, rinsing and drying.
  • a first object of this invention aims to achieve the above object, therefore consists of a method for cleaning, disinfecting, rinsing and drying objects or instruments, characterized in that in a first step, these instruments are immersed in an alcoholic alkaline solution for at least 4 hours and at room temperature, and that in a second step they are subjected to the action of an deoxidizing alkaline liquid and then at least of a mixture of a fluorinated hydrocarbon and an alcohol, the various operations of this second step being each carried out for 10 seconds to 5 minutes together with a mechanical treatment by ultrasound and a heat treatment at a temperature between 30 and 50 o C.
  • a second object of this invention consists of a device for cleaning, disinfecting, rinsing and drying instruments, particularly of metal or synthetic material, characterized in that it comprises a container provided with heating means and d 'an ultrasonic generator and intended to contain a liquid allowing the transmission of ultrasound; by the fact that this container is closed by a removable cover; and by the fact that this cover has a level control opening and at least two openings each intended to receive a test tube immersed in said liquid and intended to contain a cleaning, rinsing and / or drying liquid, each test piece being itself intended to receive in the service position a cleaning basket intended to contain said instruments and of which the lower part at least is perforated.
  • the alcoholic alkaline solution used in the first stage can consist of a mixture of potassium hydroxide and propylene glycol, the potassium hydroxide content generally being around 5%.
  • This first step which is used to carry out a first cleaning of the instruments, for example small dental instruments, as well as the disinfection of these, is carried out at room temperature for at least 4 hours but preferably for at least 8 to 10 hours , the instruments being simply immersed in the mixture, generally without agitation.
  • the second step comprises four operations, which generally last each approximately 1 minute and which are carried out in conjunction with heating to a temperature of approximately 36 to 43 ° C and to a mechanical cavitation action produced by ultrasound.
  • the main container intended for cleaning, rinsing and drying operations comprises a tank 1, for example made of stainless steel, equipped with an ultrasonic generator 2 of a given frequency and a heating device 3 with thermostat control.
  • This tank 1 contains an alkaline deoxidizing liquid 4 transmitting the vibrations due to ultrasound well and protecting the metal of the tank; one can use for example a liquid such as "DG 2" at 1% in water (product of Jean Gallay S.A. Geneva).
  • the tank 1 is closed by a cover 5 detachably fixed by metal spring tabs 6 cooperating with projections 7 on the outside wall of the tank 1.
  • the cover 5 is pierced with a level control opening 8 and four openings 9 intended to each receive a test tube 10 immersed in the thermostatted bath 4; it therefore serves as a support for these test pieces 10.
  • Each test piece 10 for example made of glass, as illustrated in FIGS. 2 and 3, comprises a ring 11, for example made of metal, set on the neck of the test piece 10 and serving as a flange to maintain i specimen 10 in position immersed in the bath 4.
  • a solid plug 12 (see Figure 3) may be further provided for closing the test tube 10 when the latter is not used and thus prevent the evaporation of the liquid 13 which it contains.
  • the liquid 13 is one of the cleaning, disinfection, rinsing and drying solutions mentioned respectively with respect to the process.
  • the test pieces 10 are intended to receive, in the service position, cleaning baskets 14 containing small instruments such as dental instruments.
  • These baskets 14 (see FIGS. 4A and 4B), for example made of stainless steel, have a perforated lower part 15, more particularly made of a fine lattice, as well as the bottom 15 'of these baskets 14; these can also be made completely in a fine mesh.
  • a washer 16 is further set on the upper opening of the baskets 14, and rests, in the service position (see FIG. 2), on the ring 11 of the test pieces 10. Finally, a removable handle 17 is provided for handling these baskets 14. Manipulation is particularly necessary during the passage from one test piece to another in the cleaning cycle, and the handle 17 is then used to hold the basket 14 in order to drain the treatment liquid from the first test piece before d 'immerse the basket 14 in the treatment liquid of a second test tube.
  • Each basket 14 can contain approximately 30 to 50 small instruments such as the dental instruments already mentioned by way of example.
  • This container comprises a tank 18, an upper plate 19 pierced here by four or vertures 20, and a cover 21.
  • the tank 18 is filled with an alcoholic alkaline cleaning and disinfection liquid, for example a mixture of potassium hydroxide and propylene glycol, in which the instruments to be treated are simply immersed in room temperature for at least 4 hours, preferably for at least 8 to 10 hours. For this, the instruments are placed in the baskets 14, and these are immersed in the bath, the washer 16 of the baskets 14 resting on the upper plate 19.
  • an alcoholic alkaline cleaning and disinfection liquid for example a mixture of potassium hydroxide and propylene glycol
  • the device according to the invention therefore allows the user, for example the dentist, to have relatively ready-to-use instruments easily and quickly.
  • the device can also be used for cleaning instruments, articles or parts of larger dimensions than those of dental instruments for example. This then requires in particular the increase in the capacity of the containers and the cleaning baskets, and possibly the addition of a mechanized or even automated system for transporting the objects to be cleaned on the one hand and for transferring the cleaning baskets from one solution in the following.
