Description

 The invention relates to medicine, namely to dental instruments, and can be used to remove plaque and polish teeth.

 A device for removing plaque and polishing teeth containing a spray nozzle attached to the collector with water supply channels and an air suspension of abrasive material, rigidly connected to the collector, a handle and a reservoir for abrasive material (US patent N 4950160, CL 433/88, 1980 )

 The main disadvantage of the known device is the inability to adjust the flow rate of water and abrasive material, which dramatically reduces the operational characteristics of the device.

 A device is known for polishing teeth with a fluid jet under pressure and an abrasive, containing a spray nozzle rigidly fixed in the skeleton with water supply channels and an air suspension of abrasive material, connected to the skeleton of the casing with a reservoir with abrasive material located in its lower part (US patent N 4648840, cl 433/125, 1987).

 A disadvantage of the known device is the lack of the ability to adjust the flow rate of water and abrasive material and, as a consequence, low performance.

 The closest in essence to the claimed is a device containing a spray nozzle with channels for supplying water and air suspension of abrasive material, a control unit with water and air flow regulators located in it, connected with corresponding supply channels, and also a reservoir for abrasive material located inside the unit Management ("MEDICAL" Dentists' Elpression: CATALOG, 1994-1995).

 In the known device, the spray nozzle is connected to the control unit through a flexible hose supplying water and an air suspension of the abrasive material, which causes inconvenience if the device's operating mode is necessary to change, since the controls for water flow and air flow are spaced with the spray nozzle.

 The use in the known design of the tank for abrasive material located inside the control unit, necessitates pouring the abrasive material from the packaging container into the tank, which makes it difficult to meet the requirements for sterility of the material.

 In addition, the integral connection of the flexible inlet hose to the spray nozzle makes it difficult to carry out mandatory sterilization of the spray nozzle.

 The invention is aimed at improving ease of use, as well as ensuring sterility of both the tool itself and the abrasive material.

 This result is achieved due to the fact that in the device containing the spray nozzle with channels for supplying water and air suspension of abrasive material, a control unit with water and air flow regulators located in it associated with respective supply channels, as well as an abrasive reservoir connected with the input of the channel for supplying an air suspension of abrasive material and with the output of the air flow controller, while the output of the water flow controller is connected to the water supply channel, the control unit is made with the possibility of detachable tight connection to the reservoir for abrasive material and is rigidly connected to the spray nozzle, moreover, a needle-shaped nozzle is installed at the outlet of the air flow regulator, and the inlet of the air suspension of the abrasive material is connected to the reservoir for the abrasive material through the reversing chamber.

 Distinctive features of the claimed device are the execution of the control unit with the possibility of detachable tight connection to the abrasive material reservoir, the implementation of a rigid connection between the control unit and the spray nozzle, the installation of a needle-shaped nozzle at the outlet of the air flow regulator, the connection of the inlet of the air suspension supply channel of the abrasive material to the abrasive reservoir material through the receiver camera.

 The transfer of the control unit with the air and water flow regulators located directly in it to the spray nozzle and the rigid connection between them provide operational control of the device’s atomizer.

 The possibility of detachable tight connection of the control unit to the abrasive tank allows to increase the usability of the device and simplify compliance with the sterility requirements of the abrasive material, since the proposed design allows the packaging standard container itself to be used directly as an abrasive material tank, the casing of which simultaneously functions as a handle devices, while a needle-shaped nozzle with an air filter is installed e at the outlet of the air flow regulator, used to pierce the protective foam covering the neck of a standard packaging capacity.

 Using the receiver improves usability by increasing the uniformity of the suspension.

 The drawing shows a device with partial cuts, a General view.

 A device for removing plaque and polishing a tooth comprises a control unit 1, rigidly connected to the spray nozzle 2, a reservoir 3 for abrasive material, connected using a sealed connection 4 to the control unit 1. In the control unit there is a water flow regulator 5 and an air flow regulator 6. The inputs of the regulators of the flow of water and air are connected with the inlet channel 7 of the water and the inlet channel 8 of the air. The water and air supply channels are connected to a standard fitting 9. The output of the water flow regulator is connected to the water supply channel 10, and the output of the air flow regulator through the needle-shaped nozzle 11 covered by the air filter 12 forming the receiver is connected to the abrasive reservoir 3, with which the channel 13 for supplying an air suspension of abrasive material is also connected.

 The device is used as follows.

 The standard packaging container, which simultaneously acts as a handle and a reservoir 3 for abrasive material, is fixed on the control unit 1 by means of a detachable (threaded) tight connection 4. In this process, a protective film is punched through the needle-shaped nozzle 11 and covers the neck of the packaging container (not shown) .

 Water and air under pressure from a standard fitting 9 through the inlet channel 7 of the water and the inlet channel 8 of the air is respectively supplied to the regulator of the flow of the ox 5 and the regulator of the air flow 6.

 Water from the outlet of the water flow regulator 5 through the channel 10 of the water supply enters the spray nozzle 2.

 Air from the outlet of the air flow regulator 6 enters the needle-shaped nozzle 11. Under the influence of vortices created by the air stream in the tank 3 for abrasive material, an air suspension of the abrasive material is formed inside the volume of the latter. Under the influence of excess pressure, the air suspension of the abrasive material enters through the receiver formed by the filter 12, which serves to eliminate abrupt changes in the concentration of abrasive in the suspension, into the spray nozzles 2 through the air suspension supply channel 13 of the abrasive material.

 At the exit of the spray nozzle 2, a swirling jet is formed, consisting of water and an air suspension of abrasive material, which is used to remove plaque and polish teeth.
