0001

FIELD OF THE INVENTION The present invention relates to a method for cleaning tubes, suction systems, suction cannula systems used in particular in the dental field, and to an apparatus for carrying out this method.

0002

BACKGROUND OF THE INVENTION Such cleanings place high demands on reliability with respect to cleaning, disinfection and general hygiene. By continuously sucking in a small amount of water or other use solution with a large amount of air, a waterway is created within the system to be cleaned. This results in unsatisfactory cleaning and disinfection. Surfaces that are not wetted promote the adhesion and drying of dirt particles and thus lack the cleaning action necessary to remove these dirt particles.

[0003] Such a device is known from German Patent Application No. 2,929,804. In addition to the drawbacks mentioned above, this known device has a number of controls that are prone to errors and breakdowns due to these drawbacks. In this known device, sewage from the effluent collection is used, which necessitates cleaning of the storage shell, with long cleaning times already proving to be a drawback.

[Problems to be Solved by the Invention] Therefore, an object of the present invention is to be able to perform reliable and complete cleaning without leaving any areas that are not cleaned (uncleaned) through a simple cleaning process, and to clean many areas. The object of the present invention is to provide a simple device that does not require any control.

[0005]

Means for Solving the Problems According to the means of the method of the present invention which solves the above problems, one or more suction connections of one or more suction tubes are connected to one or more connection ports, for example by crimping. It was connected for a short period of time, and the bulk cleaning liquid or a sufficient amount of cleaning liquid was sucked in for a short period of time.

[0006]

Operation: Liquid lumps are sucked out of the system by providing a sudden flush of high-pressure liquid, such as fresh water, optionally with added cleaning and/or disinfectant agents, for rapid cleaning. As a result, not only weakly adhering surface dirt but also strongly adhering surface dirt is washed away and removed. Also, the entire inner circumferential surface of the tube, and thus the parts that follow, are also cleaned and wetted.

[0007]

[Effects] As described above, according to the present invention, maximum cleaning action can be obtained, high-speed cleaning can be obtained, high cleaning action can be obtained due to high kinetic energy, and the entire system can be wetted. can always provide the appropriate amount of cleaning, can perform continuous cleaning, does not require expensive connecting members, and has a simple structure that allows for connection during processing or between two different The possibility of cleaning between treatments and the ergonomic operation, which can be carried out easily and quickly at any time, makes the preparation of the device for use in medical work more effective.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the structure of the present invention will be specifically explained 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 right-hand tube 1 with a suction cannula 2a is suspended and has a suction connection. The left tube 1 with section 2 is in the feeding position. A cleaning liquid 4 is contained in a container indicated by the reference numeral 3. The liquid level of this cleaning liquid is monitored by a float 5. Float 5 is current circuit 7
This switch 6 itself controls a solenoid valve 8.
control.

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

When the liquid level is high, the float 5 switches the switch 6 into the closed position, so that the current circuit 7 is closed and the solenoid valve 8 closes the inlet 9 of the cleaning liquid (preferably water).
can be switched to the position where it is cut off. The inlet 9 is filled with suitable additives, detergents or disinfectants, which may also be mixed directly in the container 3. A connection 10, 10a for a saliva suction device or a spray solution suction device projects from the container 3 and penetrates into the liquid level via a delivery tube 11, 11a.

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

Reference numeral 13 indicates a storage shell arranged on a device stand 14 which accommodates the container 3.
