Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of Application The invention comprises a water supply network and a device connected to the water supply network via a hose in each case, for supplying a disinfectant into the water supply network. The present invention relates to a dental medical device having a discharge plate having an open supply pipe and connected to an outflow pipe.

PRIOR TECHNOLOGY Such a device is known as
It is known from the description in No. 3246266. When carrying out the sterilization of fungi-contaminated waterways formed by the water supply pipe network and the connected appliances with this known device, it is necessary to clean and remove the liquid previously contained in the waterways. The waterways are filled with disinfectant. For this filling process, the device is placed in a special collection container to collect the approaching liquid during the sterilization process.

After a predetermined action time lasting up to 24 hours, the disinfectant is removed by opening the water supply from the water channel.

It is not possible to prevent the sterilizing agent from spilling out of the collecting container or flowing away with it, both in the case of a filling process and also in the case of a removal process. This may be because the operator has used a collection container with too little capacity, or due to the inherent rigidity of the instrument hose, the instrument may have accidentally moved out of the collection container, thereby causing This is because the collection container may undergo sudden changes that may cause the disinfectant to escape. The release of often aggressive disinfectants caused by the above-mentioned overflows or simultaneous flows or spills results in contamination that damages the equipment or that impairs the dental treatment space.

Means for Accomplishing the Invention The object of the present invention is to obtain a dental medical device of the type mentioned, in which the release of a disinfectant is prevented in disinfecting the germ-contaminated waterways of the device. According to the invention, a receiving device 8 is movably arranged and rests on the dispensing pan 7, which accommodates and fixes the device 4, 4a, 4b during the flow of disinfectant and directs the effluent discharged from the device downwards. It is solved by being possible.

The advantages obtained by the invention essentially lie in the utilization as collection vessel of a fixed and therefore protected from sudden change discharge pan, which is already present in many cases. In this case, the discharge pan-outflow pipe ensures a reliable discharge of the sterilizing agent, so that overflow is prevented. Due to the fact that the instrument is secured by the storage device, accidental movement of the instrument out is prevented. Furthermore, by directing the appliance flow into the discharge pan and thus into the discharge pan-outflow pipe, it is possible to continuously flow the disinfectant or the water-disinfectant mixture with a high disinfectant content into the water channel. becomes. A very strong sterilization can thereby be achieved, and the sterilization time can be defined as very short, for example half an hour, compared to about 24 hours in the case of known devices. Furthermore, after said disinfection, which is often carried out after a long downtime, for example after a weekend holiday, the waterways are flushed with water or with a water-disinfectant mixture having a low content of disinfectant. The dental treatment operation can then be continued after the instrument has been removed from the storage device and after the instrument has been removed from the dispensing pan.

Other preferred embodiments of the present invention are described in any one of claims 2 to 18, which will now be described in detail.
