[0002] Otorhinolaryngology is a surgical discipline that diagnoses and treats the ears, nose, pharynx, larynx, and related head and neck areas. The human ear is generally divided into the external auditory canal, the middle auditory canal, and the internal auditory canal. Dirt often accumulates inside the external auditory canal, which is commonly known as earwax. Excessive accumulation of dirt in the external auditory canal not only reduces human hearing, but also blocks the external auditory canal for a long time, causing diseases in the external auditory canal and is not conducive to ear health.

[0003] When the existing ear canal cleaning device is used for therapeutic cleaning of the ear canal, the excessively high fluid pressure directly impacts the eardrum, causing mechanical damage or even perforation, and the unstable temperature control of the flushing fluid can cause dizziness or discomfort; the bloated structure of the cleaning equipment leads to insufficient operational flexibility, and the complex appearance of the instrument can easily cause the patient to be nervous. During the treatment, the patient suddenly twists his head due to fear or pain, which significantly increases the operational risk; at the same time, when the existing cleaning device is used to directly flush the ear canal for treatment, since the flushing nozzle is fixed, it will cause stains to remain on the inner wall of the ear and incomplete cleaning treatment.

A temperature sensor 1204 is provided on one side of the spherical airbag 1203 and located on the outer wall of the top block 1202.

[0041] Furthermore, two groups of control switches 9 are provided and are respectively located on the outer wall of the mounting block 7. The control switches 9 are respectively located on the flushing switch and the reflux switch. The liquid outlet of the reflux pump 4 is connected to the outer wall of the waste liquid storage tank 2. An anti-slip cover 13 is provided on the outer wall of the earplug shell 1101. The material of the anti-slip cover 13 is silicone material. Two groups of cleaning components 11 are provided and are respectively located on the outer wall of the catheter 10.

[0042] The working process of the present invention is as follows: when the ear canal cleaning device for ENT nursing designed by the present invention is in operation, the control panel 3 is respectively connected to the reflux pump 4, the liquid discharge pump 5, the control switch 9, the heating rod 1109 and the temperature sensor 1204 through wires and the connection mode is electrical connection, so that the device is powered on and operated, and then the control panel 3 controls the reflux pump 4, the liquid discharge pump 5, the control switch 9, the heating rod 1109 and the temperature sensor 1204 to operate. When in use, the earplug shells 1101 of the cleaning components 11 on both sides are respectively inserted into the ear canals on both sides of the patient, and at the same time, An anti-slip cover 13 is provided on the outer wall of the earplug housing 1101. The anti-slip cover 13 is made of silicone material, which provides an anti-slip effect. The appearance of the device is similar to that of existing portable audio devices. The overall structure is simple and portable, and the device can be used at any time. The earplug housing 1101 can better fit the patient's ear canal, thereby solving the problem that the cleaning device has a bloated structure and lacks operational flexibility. At the same time, the complex appearance of the device can easily cause patients to feel nervous. During the treatment, the patient may suddenly twist their head due to fear or pain, which significantly increases the operational risk.

[0043] By installing a liquid discharge pump 5 on the outer wall of the cleaning water tank 1, wherein a silicone hose 6 is installed on the outer wall of the liquid discharge pump 5, and a mounting block 7 is provided at one end of the silicone hose 6, and a two-way joint 8 is embedded in the outer wall of the mounting block 7. Under the action of a control switch 9 embedded in the outer wall of the mounting block 7 on one side of the two-way joint 8, it is only necessary to turn on the control switch 9, thereby causing the control switch 9 to generate an electrical signal to be transmitted to the control panel 3, which will cause the control panel 3 to control the liquid discharge pump 5 to operate, so that the liquid discharge pump 5 extracts the cleaning liquid from the inner cavity of the cleaning water tank 1, and then discharges the cleaning liquid into the inner cavity of the silicone hose 6, and one end of the liquid discharge pipe 1103 is connected to the plug housing 1102 through an extension piece 1106, and the other end of the liquid discharge pipe 1103 is connected to the silicone hose 6, which will cause the cleaning liquid to pass through the liquid discharge pipe 1103 and be discharged into the inner cavity of the plug housing 1102;

[0044] A fixed bracket 1108 is provided on the inner wall of the plug shell 1102, and a liquid outlet sleeve 1107 is slidably connected to the inner wall of the fixed bracket 1108. A heating rod 1109 is provided in a ring array on one side of the fixed bracket 1108 and located on the inner wall of the plug shell 1102. A limiting piston 1110 is provided on the other side of the fixed bracket 1108 and located on the outer wall of the liquid outlet sleeve 1107. The cross section of the limiting piston 1110 is an annular structure, and the connection between the limiting piston 1110 and the plug shell 1102 is a sliding connection. When the cleaning liquid is filled into the inner cavity of the plug shell 1102, the cleaning liquid will push the limiting piston 1110 to move horizontally to one side, thereby causing the limiting piston 1110 to drive the liquid outlet sleeve 110 7 moves laterally, causing the liquid discharge sleeve 1107 to move to one side on the fixed bracket 1108. When the flexible spring 1201 is installed on the inner wall of the installation groove 1114 and the flexible spring 1201 is located on one side of the cleaning nozzle 1113, a top block 1202 is provided at one end of the flexible spring 1201, and a spherical air bag 1203 is provided on the outer wall of the top block 1202. Under the action of a temperature sensor 1204 provided on one side of the spherical air bag 1203 and on the outer wall of the top block 1202, the liquid discharge sleeve 1107 pushes the flexible spring 1201 to move outward, so that the flexible spring 1201 drives the spherical air bag 1203 to fit the eardrum through the top block 1202, so as to prevent the cleaning liquid from directly impacting the eardrum and causing mechanical damage to the eardrum.

[0045] The temperature sensor 1204 on the outer wall of the top block 1202 generates data in real time based on the ear canal temperature. At the same time, the temperature sensor 1204 generates an electrical signal which is transmitted to the control panel 3 via a wire. When the set temperature value is reached, the control panel 3 controls the heating rod 1109 to heat the ear canal so that the cleaning liquid and the ear canal temperature are consistent. This helps to solve the problem that when the ear canal cleaning device is used for therapeutic cleaning of the ear canal, excessive fluid pressure directly impacts the eardrum, causing mechanical damage or even perforation, and unstable temperature control of the flushing liquid, causing dizziness or discomfort.

[0046] One end of the liquid outlet sleeve 1107 is rotatably connected to a rotating base 1111, a turbine blade 1112 is provided at the port of the rotating base 1111, and the turbine blade 1112 is located on one side of the liquid outlet sleeve 1107, and a cleaning nozzle 1113 is provided in a ring array on the outer wall of the rotating base 1111, and a mounting groove 1114 is provided on one side of the cleaning nozzle 1113 and on the outer wall of the liquid outlet sleeve 1107. When the cleaning liquid pushes the limiting piston 1110 to move laterally to one side, and then the limiting piston 1110 drives the liquid outlet sleeve 1107 to move laterally, when the liquid outlet sleeve 1107 moves to one side on the fixed bracket 1108, the cleaning liquid will also flow in the inner cavity of the liquid outlet sleeve 1107. When the cleaning liquid impacts the turbine blades 1112, the turbine blades 1112 are rotated, and then the turbine blades 1112 drive the rotating base 1111 to rotate. At the same time, the cleaning liquid is ejected through the cleaning nozzles 1113 arranged in the annular array. Driven by the rotating base 1111, the cleaning nozzles 1113 rotate and eject the cleaning liquid, thereby rotating and flushing the ear canal. Impurities in the ear canal are impacted and fall off. At the same time, the impurities are repeatedly impacted by the rotating cleaning liquid to crush the impurities. This is beneficial to solving the problem that when the existing cleaning device directly flushes the ear canal, due to the fixed flushing nozzle, stains on the inner wall of the ear and incomplete cleaning treatment will occur.

[0047] A return pipe 1104 is provided on the inner wall of the earplug shell 1101, one end of the return pipe 1104 passes through the silicone hose 6 and extends to the outer wall of the silicone hose 6, and is connected to a return pump 4, and the other end of the return pipe 1104 passes through the earplug shell 1101 and extends to the outer wall of the earplug shell 1101, and is connected to a fixed block 1105, wherein the fixed block 1105 is connected to the bottom outer wall of the plug shell 1102. When the impurities on the inner wall of the ear canal are flushed off, the control panel 3 will control the return pump 4 to operate, so that the return pump 4 draws out the flushing liquid from the ear canal through the return pipe 1104, and then the reflux pump 4 discharges the flushing liquid into the waste liquid storage tank 2 for collection.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
