Integrated sand blaster

Abstract

The invention discloses an integrated sandblasting device, which comprises a sandblasting body, the inner cavity of which includes a coaxial and tangentially connected spherical cavity and a conical frustum cavity or an upper and lower symmetrical spherical conical frustum cavity. The front part is provided with a jack that communicates with the inner cavity, and the rear part of the sandblasting body is connected with a plugged air pipe. The cavity can be plugged with the trachea hole and the outer end is placed outside the sandblasting body. The sandblasting tube is provided with a sandblasting tube that opens the trachea hole and closes the jack when sandblasting, and closes the trachea hole and opens the plug when sandblasting is stopped. The hole is plugged; the plug-in trachea is installed on the front end of the handle through a joint, and the rear end of the handle is connected to the tail wire of the handpiece of the dental chair through a joint. The invention integrates a sandblasting body, a plugged air pipe and a sandblasting pipe, has a compact structure, is convenient to operate, can effectively prevent sand particles from being damp, and can be thoroughly sterilized.

Description

technical field [0001] The invention relates to a medical device for cleaning teeth, in particular to an integrated sand blaster. Background technique [0002] Sandblasting teeth cleaning is to use a special sandblasting tooth powder, which is sprayed on the tooth surface through the nozzle of a hand-held microblasting sandblasting machine to remove dental plaque and pigment. [0003] The traditional structure of the hand-held micro-blasting sandblasting machine includes a hand-held casing, a sand bottle is installed on the bottom of the hand-held casing, the nozzle is installed on the front end of the hand-held casing and is controlled by the valve of the sandblasting machine to open and close, and the hand-held casing The pipeline at the rear end is connected to an air pressure device with an air pressure of 0.4MPa~0.7MPa through a three-way joint. Negative pressure is generated inside the sand bottle, and the external atmospheric pressure is poured into the bottle from t...

AI Technical Summary

Problems solved by technology

[0005] 1. The valve of the sandblasting machine is too close to the nozzle to enter the deep mouth, which is inconvenient to operate

[0006] 2. The required pressure (0.4MPa~0.7MPa) is too large to be directly connected to the tail wire of the mobile phone of the dental chair (the pressure of the dental chair is ≤0.4MPa), and an additional air source or decompression is required

[0007] 3. Uneven sandblasting, because the sand grains are irregular in shape and have slight weight errors, and the sand grains are drawn out due to pressure difference, resulting in the number of sand grains being drawn out varies with the pressure change

[0008] 4. There are two small holes on the cap of the sand bottle, which cannot completely seal the sand in the bottle, and the sand is easily damp when exposed to the air.

[0009] 5. Serious sand leakage phenomenon

When the sandblasting is stopped (stop ventilation), a lot of sand particles will be stored at the nozzle and cause leakage

[0010] 6. Due to the complex internal structure, it is not easy to disassemble and disinfect
