Definitions
- the invention relates to a device for cleaning elongated dental devices, in particular handpieces, arranged in a cleaning container, a liquid emerging through spray nozzles being sprayed against the outside of the devices.
- Such a device has become known from DE-C 32 32 329, which differs from a conventional dishwasher in that the devices arranged on a sliding basket are connected to an external compressed gas source, which makes it possible to dry the interior of the devices.
- the dimensions of the known device correspond to those of a conventional dishwasher and the spray nozzles are located on the arms of a rotor in the usual way in dishwashers.
- the invention not only aims to significantly reduce the size of the cleaning container, it should also be possible to disinfect and oil the devices inside the container.
- this is only possible in an optimal manner if the longitudinal shaft rotates during the oil supply, albeit at a reduced speed compared to normal operation.
- EP-A 0300945 to arrange the device firmly in the vessel, while their drive input shafts are set by rotating pin in motion.
- the invention is based on the consideration that the desired relative movement between the drive shaft and the device can also be achieved if the drive shaft is held firmly and the device is set in motion.
- the devices in the cleaning container are arranged so as to be rotatable essentially about their longitudinal axis. This measure ensures that with fixed nozzles the entire surface of each device is hit by the liquid jet. It is therefore no longer necessary to move the spray nozzles in a circle or to arrange them in such a number from the start that the entire surface of each individual device lies in the area of the liquid jets.
- a dental cleaning device As mentioned, an essential prerequisite for the extensive use of a dental cleaning device is that it can be used for devices which have an internal drive.
- longitudinally arranged drive shafts rotatably arranged relative to the devices can be fixed relative to the cleaning container.
- the spray nozzles surrounding the devices to be cleaned do not have to be provided along the entire length of the devices. Rather, it can be provided that the spray nozzles in the cleaning container can be moved along the devices. This represents the reversal of a measure as is known per se from DE-A 28 05 934.
- the handpiece together with the supply hose attached to it can be inserted into the container at one end inserted and pulled out at the other end. This has the disadvantage that the handpiece is still wetted with disinfectants when it is put into operation.
- the disinfection device described is not suitable for proper cleaning of the device.
- FIG. 1 is a diagrammatic representation of an exemplary embodiment of the invention, the container surrounding the actual cleaning device being only indicated in outline.
- 2 shows a cross-section and top view of the carrier on which the devices to be cleaned are drivably arranged
- FIG. 3 shows the cross section through the carrier according to FIG. 2 with drives for devices without an inner drive shaft
- FIG. 4 shows a part of the carrier 2 with a drive for devices stored in a basket
- FIG. 5 the supply of the carrier according to FIG. 2 and the spray nozzles with fluids.
- a support plate 2 can be inserted into a cleaning container 1, which is only shown in outline, in the manner of a drawer, whereby fluid connections on the rear side of the support plate 2 are produced in a known manner by this insertion.
- the support plate 2 comes into movement-locking engagement with a geared motor 3 which, by means of a pinion 4, rotates the dental devices 5 attached to the support plate 2.
- a further geared motor 6 By means of a further geared motor 6, a threaded spindle 7 is set in rotation, whereby the the frames 5 surrounding the devices 8 can be adjusted along the devices 5.
- the frame 8 is supplied with cleaning and disinfection liquid via a hose line 9. This can be sprayed onto the rotating devices 5 through the spray nozzles 10, which are arranged along the circumference of the frame 8.
- FIG. 2 shows how the devices 5 fastened on the support plate 2 can be set in rotation via the pinion 4 actuated by the geared motor 3.
- the individual devices are assigned inserts 11, which are each in engagement with the central drive disk 12 via a gearwheel.
- Each insert 11 is held in the support plate 2 by locking lugs 13.
- Lines 14 and 15 run in the support plate, which end in support pins 16 with which the devices 5 can be connected in a rotationally fixed manner.
- Coupling members 17 run inside the trunnion 16 and can be brought into engagement with the ends of the drive shafts running inside the device 5.
- FIG. 3 In the case of devices without an inner drive shaft, there are simplifications which can be seen from FIG. 3.
- the inserts 11 are designed here, as in FIG. 2, for the most twist-on insertion (left in FIG. 3) or insertion (right in FIG. 3) of dental instruments.
- the drive takes place in each case via a gear wheel 18 which is attached to the end of the insert 11 and which engages with the drive disk 12.
- the device according to FIG. 2 basically only removes the coupling members 17 for holding the drive shafts not provided here.
- Dental instruments the handle of which is not designed as a sleeve, can of course not be attached to a trunnion. It is also not necessary to insert it into a trunnion if there is no interior of the device to be rinsed with cleaning agents or disinfectants anyway.
- the device according to the invention is to be used for the treatment of surgical instruments, such as probes, mirrors, scalpels, etc., it is sufficient to arrange these instruments in a basket 19 which has an attachment 20 with which it rotates into a drive 21 ein ⁇ can be coupled, as shown in Fig. 4.
- the washing machine described above is for cleaning, disinfection and care of dental
- Air is blown through the media channel 14, which leads to the gears, and the cleaning agents and disinfectants from the bottle 40 are optimally atomized in the mixing chamber 23.
- the interior of the transmission is blown dry and maintenance oil from the bottle 24 in the mixing chamber 23 is again atomized optimally and in a quantity-saving manner and blown to the respective rotating instruments.
- pressure switches 25 are installed in each of the pipes.
- disinfectants and cleaning agents are fed via a pump 28 to the frame 8 in a storage container 26 via a filtered suction nozzle 27, and optimal cleaning and disinfection of the instruments is achieved by the upward and downward movement and the rotating instruments.
- the contaminated medium flowing into the collecting trough 29 flows back into the container 26.
- the coarse dirt residues are deposited as sediments 30 on the bottom of the container 26. These sediments fall through the sieve 31 and are not washed away by the suction liquid 27 through the suction nozzle.
- the washed-in oil 32 floats in the container 26 due to the lower specific weight and is transferred to the disposal container 33.
- the device is switched off by the level indicator when the container is full.
- the washing machine is additionally equipped with a printer which records the cleaning process for documentation.
- Media channels 14 and 15 are deactivated when cleaning probes, mirrors, scalpels etc.
- the media containers 40 and 24 can be exchanged by a quick-release fastener, the different connections being intended to prevent confusion.
- a cassette autoclave arranged below the container 1, the instruments can be sterilized if necessary and stored in the cassette 38 in sterile packaging up to the insert 2.
- the different instruments can be prepared quickly and optimally, including disinfection. If necessary, the instruments can also be sterilized.
