DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning a suction tube by connecting a tube end of a suction tube of a dental treatment table to a connection port of a cleaning container filled with a cleaning liquid. .

[0002]

2. Description of the Related Art Such a known method is carried out in a device provided on a dental treatment table (see DE-A-29 29 804). The known device is provided with a cleaning container containing a cleaning agent, which is connected via a solenoid valve to a high-pressure water conduit. Extending from the cleaning container is a cleaning conduit which terminates at an easily accessible location and has a mating connection. The known device further comprises a suction line connected to the low-pressure system and the siphon, at the end of which a suction nozzle is mounted, which is connected to the mouth of the patient. A suction handpiece that can be introduced is fitted over the suction handpiece. Since blood and saliva adhere to the inner wall of the suction conduit, it is necessary to occasionally clean and disinfect the suction conduit. For this purpose, the suction handpiece is removed from the suction nozzle and the suction nozzle is fitted over the connection of the washing conduit. During this fitting, the switching contact is operated, whereby the solenoid valve is switched, so that water under pressure is introduced into the container, and the water mixed with the cleaning agent present in the container is passed through the cleaning conduit. And through the suction conduit to clean the suction conduit. When the suction nozzle of the suction conduit is again removed from the connection of the cleaning conduit, the switching contact is operated again, the solenoid valve is switched again, and the pressurized water does not enter the container. However, this document does not describe how long the suction nozzle has to be fitted over the connection of the cleaning conduit for the cleaning process of the suction conduit.

[0003]

The object of the present invention is to improve the method described at the outset and to further improve the cleaning effect of the suction tube.

[0004]

SUMMARY OF THE INVENTION According to the invention, this object is achieved in that the suction connection is pressed against the connection for a short time so that the trapped liquid mass is pushed out through the suction tube at a high speed. It was solved by doing.

[0005]

In accordance with the method of the present invention, the kinematic energy of the mass (es) of liquid extruded through the suction tube is greater than when the cleaning liquid passes continuously through the suction tube. , Provide better cleaning effect. In this manner, not only the weakly adhered surface dirt but also the strongly adhered surface dirt can be washed away from the corrugated inner wall surface of the suction nozzle.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the configuration of the present invention will be specifically described with reference to the embodiments shown in the drawings.

In the drawing, a tube with a suction connection 2 is designated by the reference numeral 1, of which the tube 1 on the right-hand side with a suction cannula 2 a is suspended and on the left-hand side. The suction connection 2 of the tube 1 is connected to the connection port at the supply position. A cleaning liquid 4 is contained in a container indicated by reference numeral 3. The liquid level of this cleaning liquid is monitored by the float 5. Float 5
Controls the switch 6 of the current circuit 7, which itself controls the solenoid valve 8.

If the liquid level is too low, the float 5 will drop and open the switch 6, which switches the solenoid valve 8 so that the inlet 9 is open (this condition is shown). .

When the liquid level rises, the float 5 switches the switch 6 to the closed position, so that the current circuit 7 is closed and the solenoid valve 8 is connected to the inlet 9 of the washing liquid (preferably water).
Can be switched to the position to shut off. An appropriate additive, cleaning agent or disinfectant is put in the inflow portion 9, and these cleaning agents and the like may be directly mixed in the container 3. Connections 10, 10a for the saliva sucker or the spray solution sucker protrude from the container 3 and penetrate into the liquid level via the outlet pipes 11, 11a.

The liquid is sucked into the tube 1 only while the suction port 2 is pressed against the connection port 10 or 10a. When pressed for a short time, the liquid clumps, which entrains dirt in the system due to velocity and kinetic energy. A suction connection, not shown, with an associated delivery tube can be used for continuous cleaning of another system. An overflow 12 is provided to prevent the washing liquid from overflowing from the container 3.
This overflow 12 opens to a suitable outlet.

Reference numeral 13 designates a saliva tray arranged on an apparatus stand 14 for accommodating the container 3.
