Blockage may also affect hearing, so the ear canal needs to be cleaned. The existing method of cleaning the ear canal is generally to remove large foreign bodies in the external auditory canal with tweezers; and some small foreign bodies and those adsorbed on the external auditory canal need to be rinsed with normal saline.

[0003] The conventional method is to flush the external auditory canal with a syringe without a needle. Physiological saline is injected into the syringe and then the external auditory canal is cleaned. During flushing, some small foreign matter or oily matter may adhere to the external auditory canal. Flushing with a syringe is to inject inward along the upper wall of the external auditory canal with a smaller force. Therefore, the impact on the foreign matter in the ear canal is smaller, and it is not easy to flush the foreign matter in the ear canal, which makes it inconvenient to clean the external auditory canal.

[0018] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0019] The ear canal cleaning device described in this embodiment is as follows: Figure 1 , Figure 2 and Figure 3As shown, the syringe body includes a syringe body, which includes a vertically arranged syringe barrel 1 and a nipple 3. The nipple 3 is located at the top of the syringe barrel 1. A piston and a piston rod are arranged in the syringe barrel 1. The structure of the nipple 3, syringe barrel 1, piston and piston rod is consistent with that of the existing syringe.

[0020] A fixing tube 8 is fixed to the end of the nipple 3, and the fixing tube 8 is connected to the nipple 3. The nipple 3 is located at the top of the syringe 1, and the top of the nipple 3 is the end. The fixing tube 8 is vertically fixed to the top of the nipple 3, and the inner wall of the nipple 3 is flush with the inner wall of the fixing tube 8, so that the thickness of the fixing tube 8 can be smaller than the thickness of the nipple 3, thereby reducing the diameter of the sleeve 7.

[0021] A blocking block 10 is horizontally fixed at the top end of the fixed tube 8. The blocking block 10 is a circular plate. The diameter of the blocking block 10 is consistent with the diameter of the outer wall of the fixed tube 8, so that the blocking block 10 can block the top end of the fixed tube 8 to prevent the water in the fixed tube 8 from flowing out from the top end. Of course, in some embodiments, the blocking component can also include a groove with a notch facing downward and a circular inner wall. An internal thread is provided on the inner wall of the groove, and an external thread is provided on the outer wall of the top end of the fixed tube 8. The groove and the fixed tube 8 are detachably matched through the threaded fit of the groove and the fixed tube 8, and the groove is equivalent to the plug of the existing pipeline. The content of this paragraph as a whole constitutes a blocking component that seals the end of the fixed tube 8 away from the nipple 3.

[0022] A soft brush 9 is fixed to the outer wall of the fixed tube 8. The soft brush 9 can be made of animal hair or plant fiber. The soft brush 9 can be glued to the outer wall of the fixed tube 8 by glue. The glue can be acrylic glue. The adhesion method of the soft brush 9 and the fixed tube 8 can also be consistent with the adhesion method of the existing test tube brush. Of course, the soft brush 9 can also be fixed to a rubber sleeve. The rubber sleeve is fixed to the fixed tube 8. The side wall of the fixed tube 8 is provided with a plurality of through holes that communicate with the inside and outside. The fixed tube 8 is independently sleeved with a sleeve 7 that makes the soft brush 9 fit the outer wall of the fixed tube 8. By sleeve 7 on the fixed tube 8, the soft brush 9 can be bent as a whole to fit the outer wall of the fixed tube 8. Since the thickness of the fixed tube 8 is less than the thickness of the nipple 3, the diameter of the inner wall of the sleeve 7 can be consistent with the diameter of the outer wall of the nipple 3, so that the diameter of the sleeve 7 can be reduced.

[0023] A first fixing plate 4 is horizontally fixed to the bottom of the outer side wall of the sleeve 7, a second fixing plate 6 is fixed to the outer side wall of the syringe 1 near the nipple 3, the second fixing plate 6 is horizontally fixed to the top of the side wall of the syringe 1, a fixing rod 5 is vertically fixed to the side of the first fixing plate 4 near the second fixing plate 6, the fixing rod 5 is vertically fixed to the bottom of the first fixing plate 4, and a first through hole for the fixing rod 5 to pass through is opened on the second fixing plate 6;

[0024] The fixing rod 5 is provided with a second through hole for the plug 12 to pass through. Figure 1 and Figure 3 As shown, when the syringe 1 is in a vertical state, the latch 12 is located in the second through hole, and when the latch 12 is located at the top of the second fixing plate 6, the sleeve 7 is sleeved on the outside of the fixing tube 8, and the latch 12 will block the downward movement of the fixing rod 5, so that the first fixing plate 4 will not move downward, and after the fixing tube 8 is located in the external auditory canal, the latch 12 is taken out of the second through hole, the first fixing plate 4 is moved toward the second fixing plate 6, the sleeve 7 is sleeved on the outside of the nipple 3, and the soft brush 9 is unfolded. The structure of the latch 12 as a whole constitutes a locking assembly that fixes the fixing rod 5 in the first through hole. Of course, in actual use, the locking assembly can also be a bolt. A threaded hole connected to the second through hole is horizontally opened on the second fixing plate 6, and the bolt is threadedly matched with the threaded hole, and the fixing rod 5 is fixed in the second through hole by the bolt.

[0025] The above two paragraphs constitute as a whole an adjustment mechanism for fixing the sleeve 7 to the outside of the fixed tube 8; in some embodiments, the adjustment mechanism can also be without the second fixed plate 6, and the fixed rod 5 is located between the first fixed plate 4 and the top of the syringe 1, and the fixed tube is sleeved on the fixed rod 5, and the fixed tube is provided with bolts for fixing it to the fixed rod 5. By sliding the fixed rod 5 and the fixed tube, the combined length of the fixed rod 5 and the fixed tube is adjusted, thereby adjusting the externalization of the sleeve 7.

[0026] A magnet is provided on the top of the second fixing plate 6, and the latch 12 is made of metal. A groove for embedding the magnet is opened on the top of the second fixing plate 6. The magnet is embedded in the groove, so that the magnet is fixed to the second fixing plate 6. The latch 12 can be fixed by the magnet, which can prevent the latch 12 from falling off from the second through hole on the fixing rod 5 in a natural state. Of course, the suction force between the magnet and the latch 12 is small, which makes it easy to take the latch 12 out of the second through hole.

[0027] A slider 11 is fixed to the inner wall of the sleeve 7 near the nipple 3, and a slider 11 is fixed to the inner wall of the bottom end of the sleeve 7. Preferably, two sliders 11 are provided, and are symmetrical on the left and right, so as to have a better limiting effect on the sleeve 7. A sliding groove is provided on the outer wall of the nipple 3 for the slider 11 to be inserted and slide along the length direction of the nipple 3. The slider 11 slides up and down in the sliding groove. By sliding the slider 11 in the sliding groove, the rotation of the sleeve 7 can be restricted, so that the sleeve 7 can move up and down on the fixed tube 8 and the nipple 3.

[0028] The outer wall of the syringe 1 near the nipple 3 is fixed with a liquid inlet tube 2, which is horizontally fixed on the outer wall of the top of the syringe 1, and the liquid inlet tube 2 is connected to the inside of the syringe 1. The top of the side wall of the syringe 1 is provided with a connecting hole for connecting the liquid inlet tube 2 and the inside thereof, and a valve is installed on the liquid inlet tube 2, and physiological saline can be sucked into the syringe 1 through the liquid inlet tube 2, and the valve on the liquid inlet tube 2 can prevent the physiological saline in the syringe 1 from flowing out of the liquid inlet tube 2 when it is injected into the fixed tube 8; when in use, the liquid inlet tube 2 is The valve on the liquid tube 2 is opened, and then the physiological saline is sucked from the liquid inlet tube 2 into the syringe 1 through the piston and the piston rod in the syringe 1. When cleaning the external auditory canal, the valve on the liquid inlet tube 2 is closed, and then the physiological saline in the syringe 1 is injected into the fixed tube 8 through the nipple 3; of course, in some embodiments, the top end of the fixed tube 8 can also be opened by a blocking component, and then the physiological saline is sucked into the syringe 1 from the top end of the fixed tube 8, or the physiological saline is sucked into the syringe 1 through the through hole in the side wall of the fixed tube 8.

[0029] Working principle:

[0030] When cleaning the external auditory canal, first, sleeve the sleeve 7 on the outside of the fixed tube 8, and bend the soft brush 9 to stick to the outer wall of the fixed tube 8, and then suck the physiological saline into the syringe 1 through the liquid inlet tube 2; second, hold the syringe 1 and insert the sleeve 7 into the patient's external auditory canal. During the insertion process, since the soft brush 9 is blocked by the sleeve 7, the soft brush 9 will not come into contact with foreign matter in the external auditory canal. In this way, when the fixed tube 8 is inserted into the external auditory canal, the soft brush 9 will not push the foreign matter in the external auditory canal into the auditory canal (tympanic membrane and middle auditory canal); third, move the second fixing plate 6 toward the first fixing plate 4, move the sleeve 7 toward the nipple 3, and sleeve the sleeve 7 on the outside of the nipple 3 so that the soft brush 9 can be bent and attached to the outer wall of the fixed tube 8; The brush 9 is unfolded and contacts the external auditory canal, and then the physiological saline in the syringe 1 is injected into the fixed tube 8. Because the top end of the fixed tube 8 is blocked by the block 10, the water will not rush out from the top end of the fixed tube 8, so that the physiological saline will flow out from the through hole of the side wall of the fixed tube 8 to rinse the external auditory canal wall. At the same time, the syringe 1 can be held to rotate the fixed tube 8 to make the soft-bristled brush 9 scrub the external auditory canal wall to separate the foreign matter from the external auditory canal wall. When flushing, the flushed ear canal can be tilted downward to facilitate the outflow of water in the ear canal. After cleaning, the fixed tube 8 is taken out of the internal and external auditory canals. In this way, the soft-bristled brush 9 can also take out the foreign matter in the ear canal, making the cleaning of the ear canal more convenient and clean.
