The present invention has following beneficial effect compared with the prior art:
1, novel structure, easy to use, comfortable, safety.
2, flushing pressure, temperature, angle are controlled.
3, flushing process is without excessive, seepage, recyclable flushing liquor mixture.
4, adopt electrodynamic pump compacting to execute and curative effect is significantly improved to external auditory meatus flushing.

Detailed description of the invention
Be further described the present invention below in conjunction with accompanying drawing and example, embodiment is see Fig. 1-Figure 12.
See Fig. 1, Fig. 6, for solving the defect of the uncontrollable existence of prior art flushing pressure, adopt low pressure 24V DC source, the rotating speed of direct-flow micromachine 9 is changed by adjust blood pressure, the i.e. rotating speed of micro centrifugal pump, and debug the voltage of best flushing dynamics, as use voltage, achieve flushing liquor pressure, safety is controlled.The flushing sap cavity 15 of three groups of flushing liquor control device 11 on it is set in described flushing control device container 1 and adds saltwater injection, hydrogen peroxide, antibiotic three kinds of flushing liquors respectively to meet clinical demand, can the independent implementation and operation of three people be supplied.Described irrigator 2 is arranged poly-sap cavity 17 to be formed evenly to have the flushing liquor of dynamics to flow through to hold between negative tube 22 and outer tube 23 and by chamfering in outer tube 23 90 ° by the gathering of flushing liquor and directly rinse external auditory meatus wall, overcome existing syringe and directly rinse tympanum and may cause potential harm.Negative pressure cavity 18 on described irrigator 2, design disconnects the organization plan of isolation negative tube in negative pressure cavity both sides, can reach the effect reclaiming and rinse mixed liquor, and not pollute negative pressure source.
The present invention is applicable to that external auditory meatus is earwaxed, foreign body of external anditory canal, otitis externa, otitis media patient clinical practice.
