The technical field is as follows:

the invention relates to an accessory on a medical instrument, in particular to a connector on a cleaning liquid spray head for a handheld dental power machine.

Background art:

as shown in fig. 3, the tail of the conventional pneumatic dental therapeutic apparatus b is provided with an air inlet channel 5 and an air outlet channel 7 which are arranged side by side, and compressed air is introduced from the air inlet channel 5 and then is led out from the air outlet channel 7, so that the power head can be driven to rotate by introducing the compressed air so as to drive corresponding dental components to treat teeth. Because the sanitizer is through 4 direct spouts in pneumatic type dental treatment apparatus b intake duct 5 of the spray tube of inserting in the intake duct on the sprinkling irrigation a, under the drive of the pressure of spouting, the cleaning solution can be followed the gas outlet duct blowout, and one is difficult to permeate the clearance between the rotating part, and two come, the spun cleaning solution can spray operator on one's body, influences the normal clean operation of operator.

The invention content is as follows:

the invention aims to provide an adapter which prevents cleaning liquid from being sprayed out of an air outlet channel of a pneumatic dental therapeutic apparatus and enables the cleaning liquid to smoothly permeate into a gap between rotating parts.

The pneumatic dental therapeutic apparatus comprises an adapter body, a cleaning solution channel arranged on the adapter body and a plug arranged on the adapter body and positioned beside the cleaning solution channel, wherein the diameter of the channel at one end of the cleaning solution channel corresponds to the diameter of a spray pipe on spray irrigation, the diameter of the other end of the cleaning solution channel corresponds to the outer diameter of an air inlet channel of the pneumatic dental therapeutic apparatus, a cylindrical notch is arranged on the adapter body beside the other end of the cleaning solution channel, the diameter of the cylindrical notch corresponds to the outer diameter of an air outlet channel of the pneumatic dental therapeutic apparatus, the plug is arranged in the cylindrical notch, and the diameter of the plug corresponds to the inner diameter of the air outlet channel of the pneumatic dental therapeutic apparatus.

During the use, the other end and the cylindrical notch of the cleaning solution passageway on the adapter body cup joint respectively on the intake duct and the gas outlet duct of pneumatic type dental treatment apparatus, the stopper fills in the gas inlet duct, seal the gas outlet duct, then insert the cleaning solution passageway from one of them end of cleaning solution passageway with the spray tube on the sprinkling irrigation, spout into the cleaning solution through the spray tube, because the gas outlet duct is sealed, and thus, the cleaning solution just can not follow the gas outlet duct blowout, avoided spun cleaning solution to spray operator on one's body and influence the normal clean operation of operator, and simultaneously, the cleaning solution of spouting is under hydraulic effect, after the clearance between the infiltration rotating part, spill over from the drive unit head, realize clean effectively and lubricated rotating part. Adopt the stopper setting in cylindrical recess, like this, when connecting the adapter, seal the gas outlet channel, it is very convenient to use to, can utilize the spray tube to apply the pressure on the adapter, keep the closure of stopper, avoid the stopper to drop under the pressure effect of cleaning solution, guaranteed the sealing effect of stopper.

Here, the material of adapter is silica gel. Utilize the elasticity of silica gel, guarantee the leakproofness of connecting, avoid the cleaning solution under the pressure effect, ooze from the intubate and the passageway of one of them one end of cleaning solution passageway between.

Compared with the prior art, the invention has the advantages of preventing the cleaning liquid from being sprayed out from the air outlet channel of the pneumatic dental therapeutic apparatus and leading the cleaning liquid to smoothly permeate into the rotating parts.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a state diagram of the present invention in use;

fig. 3 is a state view of a conventional pneumatic type dental treatment instrument using spray irrigation for cleaning.

The specific implementation mode is as follows:

the invention will now be described in further detail with reference to the accompanying drawings and examples:

as shown in fig. 1, the pneumatic dental treatment device comprises an adapter body 1 made of silica gel, a cleaning liquid channel 2 arranged on the adapter body 1, and a plug 3 arranged on the adapter body 1 and positioned beside the cleaning liquid channel 2, wherein the channel pipe diameter of one end 2a of the cleaning liquid channel 2 corresponds to the diameter of a spray pipe 4 on a spray irrigation pipe a, the diameter of the other end 2b of the cleaning liquid channel 2 corresponds to the outer diameter of an air inlet pipe 5 of a pneumatic dental treatment instrument b, a cylindrical notch 6 is arranged on the adapter body 1 beside the other end 2b of the cleaning liquid channel 2, the diameter of the cylindrical notch 6 corresponds to the outer diameter of an air outlet pipe 7 of the pneumatic dental treatment instrument b, the plug 3 is arranged on the axis in the cylindrical notch 6, and the diameter of the plug 3 corresponds to the inner diameter of the air outlet pipe 7 of the pneumatic dental treatment instrument b.

As shown in fig. 2, during the use, the other end 2b and the cylindrical recess 6 of the cleaning solution passageway 2 on the adapter body 1 cup joint respectively on the intake duct 5 and the air outlet 7 of pneumatic type dental treatment apparatus b, stopper 3 stopper is in air inlet 7, seal air outlet 7, then insert cleaning solution passageway 2 from one of them one end 2a of cleaning solution passageway 2 with spray tube 4 on the sprinkling irrigation a, spout the cleaning solution through spray tube 4, because air outlet 7 is sealed by stopper 3, like this, the cleaning solution just can not be followed air outlet 7 blowout, avoided spun cleaning solution to spray operator's on one's body and influence the normal cleaning operation of operator, simultaneously, the cleaning solution of spouting is under hydraulic pressure, after the clearance between the infiltration rotating parts, spill over from drive unit head 8, realize effectively cleaning and lubricated rotating parts.
