A fixing block 8 is fixedly connected to the inner wall of the main body 1. When using the device, the valve on the outer wall of the liquid infusion tube 2 can be opened first to add the liquid medication into the device through the liquid infusion tube 2. Then, the rotating block 3 is rotated to fully stir the liquid medication inside the device. Then, the liquid extraction pump 7 is started to deliver the liquid medication inside the device to the catheter 6 through the liquid outlet tube 9 for infusion into the patient's ear canal. After the infusion is completed, the catheter 6 can be replaced through the locking mechanism 4.

[0026] like Figure 3 As shown, this utility model provides a technical solution: Preferably, a rotating shaft 11 is fixedly connected to the right side of the rotating block 3, and a bevel gear 12 is fixedly connected to the right end of the rotating shaft 11. A first bevel gear ring 13 is meshed with the outer wall of the bevel gear 12, and a second bevel gear ring 14 is meshed with the outer wall of the bevel gear 12. A plurality of outer stirring rods 15 are fixedly connected to the inner surface of the first bevel gear ring 13, and a plurality of inner stirring rods 16 are fixedly connected to the inner surface of the second bevel gear ring 14. The outer wall of the first bevel gear ring 13 is rotatably connected to the fixed block 8, and the outer wall of the second bevel gear ring 14 is rotatably connected to the fixed block 8. The rotating shaft 11... The outer wall is rotatably connected to the fixed block 8. When stirring the inside of the device, the rotating block 3 can be rotated first. The rotating block 3 can drive the bevel gear 12 to rotate through the rotating shaft 11. The rotation of the bevel gear 12 can drive the first bevel gear ring 13 and the second bevel gear ring 14 to rotate simultaneously in opposite directions. The rotation of the first bevel gear ring 13 can drive the outer stirring rod 15 to rotate, and the rotation of the second bevel gear ring 14 can drive the inner stirring rod 16 to rotate in the opposite direction, so as to fully stir the medicine liquid inside the device, so that the components in the medicine liquid can be evenly distributed, ensuring that the concentration of the medicine liquid is the same, and improving the therapeutic effect of the device.

[0027] like Figures 4-6As shown, this utility model provides a technical solution: Preferably, the locking mechanism 4 includes a mounting block 41, a knob 42 rotatably connected to the right side of the mounting block 41, a threaded rod 45 fixedly connected to the left side of the knob 42, movable plates 44 threadedly connected to both ends of the outer wall of the threaded rod 45, U-shaped plates 46 fixedly connected to the opposite surfaces of the two movable plates 44, a slider 47 fixedly connected to one end of the U-shaped plate 46, a locking block 20 fixedly connected to the other end of the U-shaped plate 46, and an annular groove 17 formed on the lower part of the outer wall of the connecting column 5. The outer wall of block 20 is movably connected to the annular groove 17. The threads on the left and right sides of the outer wall of threaded rod 45 are opposite in direction. A sealing gasket 19 is fixedly connected to the upper end of the outer wall of the outlet pipe 9. A connecting plate 43 is rotatably connected to the upper side of slider 47. A moving ring 18 is rotatably connected to the other end of connecting plate 43. A limiting block 48 is fixedly connected to the lower side of slider 47. The upper side of moving ring 18 is movably connected to the sealing gasket 19. Two limiting grooves 49 are opened on the lower side of the inner wall of mounting block 41. The outer wall of limiting block 48 is slidably connected to the limiting groove 49. During the replacement of the catheter 6, the knob 42 can be turned first. Turning the knob 42 will drive the threaded rod 45 to rotate. Since the threads at the left and right ends of the threaded rod 45 are opposite, when the threaded rod 45 rotates, it can simultaneously drive the moving plate 44 to move in the middle or in the opposite direction. When the moving plate 44 moves in the opposite direction, it can drive the U-shaped plate 46 to move in the opposite direction. When the U-shaped plate 46 drives the locking block 20 to disengage from the annular groove 17, the connecting post 5 can be removed, and the catheter 6 can be replaced. When installing the catheter 6, the connecting post 5 can be fully inserted into the installation block 41 first, and then the knob 42 can be turned in the opposite direction. Similarly, turning the knob 42 will drive the two U-shaped plates 46 to move in the middle. When the U-shaped plates 46 move, they will also drive the slider 47 to move in the middle. The movement of the slider 47 will also drive the connecting plate 43 to rotate. The rotation of the connecting plate 43 can drive the moving ring 18 to rise and squeeze the moving ring 18 to improve the sealing of the device and prevent the medicine from flowing out from the gap. Replacing the catheter 6 with a new one can effectively reduce the risk of cross-infection.

[0028] The working principle of this ENT ear delivery device will be explained in detail below.

[0029] like Figures 1-6As shown, when using the device, first open the valve on the outer wall of the liquid inlet tube 2 to add the medicine into the device through the liquid inlet tube 2. Then, rotate the rotating block 3 to fully stir the medicine inside the device. The rotating block 3 can drive the bevel gear 12 to rotate through the rotating shaft 11. The rotation of the bevel gear 12 can drive the first bevel gear ring 13 and the second bevel gear ring 14 to rotate simultaneously in opposite directions. The rotation of the first bevel gear ring 13 can drive the outer stirring rod 15 to rotate, and the rotation of the second bevel gear ring 14 can drive the inner stirring rod 16 to rotate in the opposite direction, fully stirring the medicine inside the device so that the components in the medicine can be evenly distributed, ensuring that the concentration of the medicine is the same and improving the therapeutic effect of the device. Then, drip in the patient's ear canal. After the drip is finished, the catheter 6 can be replaced through the locking mechanism 4. During the replacement and disassembly of the catheter 6, first turn the knob 42. Turning the knob 42 can drive the threaded rod 45 to rotate. The threads at the left and right ends of the threaded rod 45 are in opposite directions. Therefore, when the threaded rod 45 rotates, it can simultaneously drive the moving plate 44 to move in the middle or in the opposite direction. When the moving plate 44 moves in the opposite direction, it can drive the U-shaped plate 46 to move in the opposite direction. When the U-shaped plate 46 drives the locking block 20 to disengage from the annular groove 17, the connecting post 5 can be removed, and the conduit 6 can be replaced. When installing the conduit 6, the connecting post 5 can be fully inserted into the interior of the mounting block 41, and then the knob 42 can be rotated in the opposite direction. Similarly, the rotation of the knob 42 can drive the two U-shaped plates 46 to move in the middle. While the U-shaped plates 46 are moving, the slider 47 will also move in the middle. The movement of the slider 47 will also drive the connecting plate 43 to rotate. The rotation of the connecting plate 43 can drive the moving ring 18 to rise and squeeze the moving ring 18 to improve the sealing of the device and prevent the medicine from flowing out from the gap. Replacing the conduit 6 can effectively reduce the risk of cross-infection.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
