[0048] The working principle of the control panel 126 and the control panel 127:

[0049] The single-chip microcomputer consists of a power supply, a crystal oscillator and a reset circuit to form a minimum system;

[0050] After the transformer and rectifier circuit, AC220 outputs DC12V and DC5V respectively through LM7812 and LM7805.

[0051] Both voltage control circuits are composed of inductors, capacitors, diodes and relay ports. The average voltage of the power supply output is controlled by the pull-in time of the KA port, and the on-off signal is given by the PWM control circuit; PWM adjustment is performed on DC12V (Va) and DC5V (Va2) respectively.

[0052] The PWM control circuit is composed of LM358 and LM317; LM358 is an operational amplifier, which is a DC-coupled high-gain voltage amplifier device. They are very suitable for signal conditioning, DC amplification, filtering, and can be used with external feedback components (such as capacitors and resistors between their output input terminals). Amplify the signal input to the microcontroller PWM; port 8 is the power supply port of LM358, which is powered by Va; LM317 is a three-terminal adjustable voltage regulator, a positive linear voltage regulator for voltage regulation. LM317 is very easy to use because setting the output voltage only requires two external circuits in the LM317 voltage regulator circuit. Adj port is the LM317 control pin, which is controlled by Va2.

[0053] LCD1602 is a liquid crystal display, which is used to display the flushing parameters after analog-to-digital conversion by ADC0804.

[0054] Operation process: let the patient's earlobe be located above the waste liquid collection tank 23, the lower jaw fits against the waste liquid collection tank 23, and the head fits against the headrest 22; the medical staff uses the operating lever 1111 to adjust the soft needle 121 to a suitable position, adjusts the pressure and pulse value, and then flushes.

[0055] Application Cases

[0056] At present, there is an increasing trend of ear disease patients in my country. Hospitals still use simple and primitive flushing methods and tools to flush secretions, foreign bodies and cerumen in patients' external auditory canals, that is, earplugs and syringes are used manually. There are defects such as uncontrollable flushing pressure, angle and temperature, low efficacy and non-recyclable effect. Even direct flushing of the eardrum with flushing liquid may cause potential harm to patients. For this reason, the present application proposes an automatic, controllable and visual external auditory canal flushing instrument with safe, comfortable and effective flushing.

[0057] The needle angle control structure 11 improves the control degree of the soft needle 121, which helps medical staff to perform local flushing of the external auditory canal; by controlling the opening and closing of the hose 25 through the valve 24, the patient can intuitively see the flushing object and avoid conflicts between doctors and patients; the hand support rod 27 and the elbow support plate 28 can save the physical strength of medical staff; the illuminator 3 can get rid of the use of the headlight 34, which is more convenient; the control panel 126 can be set to pressure and pulse modes to effectively improve the flushing efficiency.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
