Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology for ear canal cleaning, and in particular to a rotary external ear canal cleaner, which is suitable for medical institutions to clean earwax, secretions and foreign objects in the ear canal of patients. Background Technology
[0002] The ear is an important auditory organ. The external auditory canal often becomes blocked by earwax buildup, inflammatory secretions, or foreign objects, requiring cleaning. When timely treatment at a hospital is needed, medical institutions typically use a rinsing bulb or syringe. The syringe tip is connected to a blunt needle, and warm water, saline solution, or cleaning solution is injected to soften the earwax in the ear canal. Then, earwax hooks or otological forceps are used to remove the earwax and other foreign objects. However, current techniques have the following problems: 1. Difficulty in controlling the injection of cleaning solution: Due to the narrowness of the ear canal, the injected liquid is prone to blockage, making it difficult to determine the amount of liquid flowing into the ear canal and to accurately control the pressure and flow rate. This can easily lead to liquid retention or spraying, especially causing middle ear damage in children; 2. Poor drainage: During injection, residual liquid mixed with earwax is difficult to drain naturally, requiring repeated operations and prolonging treatment time; 3. Cumbersome operation: Multiple insertions and removals of instruments are required, increasing patient discomfort and operational complexity. All of these factors increase the difficulty of diagnosis and treatment for doctors, affecting the effectiveness of ear canal cleaning. Therefore, there is an urgent need for an ear canal cleaning device that can simultaneously inject cleaning fluid and remove residual fluid, and is convenient and safe to operate. Summary of the Invention
[0003] The purpose of this invention is to provide a rotary external auditory canal cleaner that solves the problems of difficult-to-control hydraulic injection of cleaning fluid and difficulty in draining residual fluid after cleaning when using traditional medical external auditory canal cleaning. It can achieve efficient separation of cleaning fluid and residual fluid, improve the external auditory canal cleaning effect and operation safety, and facilitate doctors' diagnosis and treatment.
[0004] The technical solution adopted by this utility model is as follows: This rotary external auditory canal cleaner includes an infusion tube for insertion into the external auditory canal, which is fixed by a support frame. The key technical points are: the middle section of the infusion tube is fixed by the support frame; the front section of the infusion tube is fitted with a rotatable sleeve; the front end of the infusion tube is a thickened hemispherical infusion head with multiple outlets on its oblique side; a gap is left between the inner wall of the sleeve and the infusion tube; a spiral silicone blade is provided on the outside of the sleeve, the outer diameter of which gradually increases from the front end to the rear end; a dial wheel is fixed at the rear of the sleeve to drive the sleeve to rotate; the rear end of the sleeve is rotatably inserted into the annular groove of the support frame; the front end of the sleeve abuts against the rear end of the infusion head; a shell covering the rear of the soft sleeve is integrally connected to the support frame, with one side of the dial wheel exposed on the side opening of the shell; a handle is integrally connected to the lower part of the support frame, and an outflow collection box corresponding to the rear of the silicone blade is provided at the front of the handle; a drain valve is provided at the lower part of the outflow collection box; the rear section of the infusion tube extends out of the support frame for connecting a syringe.
[0005] The inner wall of the sleeve is provided with a front protruding ring and a rear protruding ring.
[0006] The silicone blades gradually become thinner from the root of the connecting sleeve outwards.
[0007] The support frame is matched with an arc-shaped elastic head fixing clip. The head fixing clip body is hinged to an ear clamp plate at one end corresponding to an ear. The ear clamp plate is provided with a snap-fit groove for fixing the support frame.
[0008] The infusion tubing is fitted with a Y-shaped connecting tube for connecting the syringe and the pressure balloon.
[0009] The effluent collection box is connected to the waste liquid tank via a conduit.
[0010] The advantages and beneficial effects of this utility model are as follows: This utility model's rotary external auditory canal cleaner uses an infusion tube inserted into the external auditory canal via a support frame. Multiple outlets are located on the oblique side of the infusion head, allowing the cleaning solution to be sprayed into the side wall of the external auditory canal, avoiding direct spraying of the cleaning solution onto the middle ear and causing damage. A rotatable sleeve is installed outside the infusion tube, with spiral silicone blades on the outside of the sleeve. The rear end of the sleeve is rotatably inserted into the annular groove of the support frame, and the front end of the sleeve abuts the rear of the infusion head. A dial is fixed at the rear of the sleeve to drive its rotation. Rotating the dial rotates the sleeve, and the rotation of the spiral silicone blades pushes the residual cleaning solution out of the ear canal. The flexible design of the silicone blades reduces ear canal irritation. One side of the dial protrudes from the side opening of the outer shell, allowing doctors to easily control its rotation with their fingers; a single-handed operation drives the blades. A handle is integrated into the lower part of the support frame for easy control of the infusion tube. An outflow collection box is included to directly collect the residual cleaning solution, which can be discharged through a drain valve. Therefore, through the combination of the above structures, the following benefits are achieved: 1. Dual-channel fluid management: While the infusion tube injects the cleaning solution, the rotating spiral blades drain the residual fluid, avoiding secondary operations. This allows the cleaning solution to be gradually injected into the ear canal via the infusion tube, and the rotating silicone blades simultaneously drain the earwax and cleaning solution mixture from the ear canal. During the cleaning process, the infusion tube does not need to be removed from the ear canal, reducing the need for repeated removal of moistened earwax using ear hooks or otolaryngological forceps, thus avoiding secondary operations. 2. Safety protection: The hemispherical infusion head and side outlet prevent eardrum damage; the flexible design of the silicone blades reduces ear canal irritation. 3. Convenient operation: The blades can be rotated with a single hand by turning the dial, making it especially suitable for pediatric patients. 4. Efficient cleaning: The progressive outer diameter design of the spiral silicone blades adapts to the shape of the ear canal, enhancing the efficiency of residual fluid drainage. This allows doctors to easily clean the ear canal by holding the support frame still, improving the cleaning effect and facilitating the doctor's diagnostic and treatment procedures.

[0022] according to Figure 1-9 This utility model will be described in further detail. Example of an embodiment: Figures 1 to 3 As shown, a rotating external auditory canal cleaner includes an infusion tube 1 fixed to the ear canal by a support frame 2. The support frame can be a horizontally placed cylindrical medical rigid PVC support block. The infusion tube 1 includes a front section 11, a middle section 12, and a rear section 13. The middle section 12 is covered and fixed by the support frame. The front section 11 is inserted into the external auditory canal and is fitted with a rotatable sleeve 5. The front end of the infusion tube is a thickened, blunt infusion head 7, which can be hemispherical. Multiple outlets 8 are provided on the oblique side of the infusion head, and the outlets are connected to the lumen of the infusion tube. The cleaning solution is injected into the inner wall of the ear canal through the outlets, avoiding direct spraying onto the eardrum and preventing eardrum damage. A gap is left between the inner wall of the sleeve 5 and the infusion tube to reduce the frictional resistance of the infusion tube and sleeve when rotating in a bent state. The infusion tube and sleeve are made of flexible medical soft PVC material that can be bent to enter the external auditory canal. A spiral flexible silicone blade 6 is provided on the outside of the sleeve 5. The outer diameter of the silicone blade gradually increases from the front end to the rear end. The root of the silicone blade is bonded to the outer wall of the sleeve. A baffle 15 is provided at the rear end of the sleeve corresponding to the silicone blade. Figure 4As shown, the silicone blade 6 preferably adopts a shape that gradually thins outward from the root of the connecting sleeve 5, forming gentle ear canal pressure and reducing ear canal irritation. A dial 4 for rotating the sleeve is fixed to the rear of the sleeve 5. The rear end of the sleeve rotates and inserts into the annular groove 14 of the support frame. An enlarged annular sleeve can be provided at the rear end of the sleeve 5 to facilitate insertion into the annular groove 14 of the support frame. The front end of the sleeve 5 is connected to the rear of the infusion head 7, and the rear end of the sleeve is connected to the support frame 2. The sleeve and blade can be rotated by rotating the dial. The support frame 1 is integrally connected to a housing 3 covering the rear of the soft sleeve. One side of the housing has an opening, and the dial 4 protrudes from the opening for easy finger control. A handle 9 is integrally connected to the lower part of the support frame. A discharge collection box 10 corresponding to the lower part of the silicone blade is provided at the front of the handle for collecting residual liquid mixed with earwax discharged from the blade. A drain valve 26 is provided at the lower part of the discharge collection box 10 to drain the residual liquid. The rear section 13 of the infusion tubing extends out of the support frame and can be used to connect a syringe.
[0023] As a further improvement, such as Figure 3 As shown, a front protruding ring 16 and a rear protruding ring 18 can be provided on the inner wall of the sleeve 5, which can form a stable gap 17 between the inner wall of the sleeve and the outer wall of the infusion tube, further reducing the frictional resistance of the infusion tube and the sleeve in the bending state.
[0024] Implementation 2, such as Figures 5 to 7 As shown, the support frame is matched with a head fixation clip 19. The head fixation clip can be an arc-shaped elastic fixation frame. Both ends of the head fixation clip body are equipped with clamps, and an ear clamp 20 is hinged to the end corresponding to one ear. The ear clamp 20 has a locking groove for fixing the support frame, and a soft pad 22 is provided on the inner side of the clamp. The rear end of the support frame can be set as a disc shape to cooperate and fix with the locking groove 21. The head fixation clip can support and fix the rotating external auditory canal cleaner, simultaneously fixing it to the patient's head, reducing the weight for the doctor's hand and facilitating operation.
[0025] Implementation 3, such as Figure 8 As shown, the infusion tubing is equipped with a Y-shaped connecting tube 23 for connecting the syringe 25 and the pressure balloon 24. The cleaning solution can be injected into the infusion tubing 1 through the syringe 25, and then the pressure balloon 24 can flexibly pressurize and push the cleaning solution into the ear canal. The syringe and the pressure balloon can be used together to provide flexible pressure control.
[0026] Implementation 4, such as Figure 9As shown, the commonly used clinical irrigation solution has a volume of 100-200ml. Since the effluent collection box 10 is not suitable for a large volume, residual liquid will overflow. The effluent collection box here is too small, possibly because it is too large to be portable and worn on a head clamp. A waste liquid tank 27 can be connected to the bottom of the effluent collection box via a drain valve 26 and a conduit. The waste liquid tank is a large-volume container that can hold more waste liquid. Alternatively, a filter screen can be installed in the waste liquid tank to filter the waste liquid, and a suction pump can be installed to accelerate the flow rate.
[0027] As a further improvement, Embodiments 2, 3, and 4 can be used in combination to further facilitate doctors' operation and diagnosis.
[0028] During use, the doctor holds the handle 9 of the rotary external auditory canal cleaner, inserts the infusion head 7 of the infusion tubing into the patient's external auditory canal, and injects the cleaning solution into the rotary external auditory canal cleaner using a syringe. The cleaning solution is injected into the inner wall of the ear canal through the infusion head of the infusion tubing. After a certain amount has been injected, the doctor can use their finger to rotate the dial 4 to rotate the silicone blades, causing the residual solution to flow out of the ear canal. More cleaning solution can be injected gradually, and then the dial can be rotated again to expel the residual solution. During the cleaning process, there is no need to repeatedly remove the infusion tubing, allowing for flexible pressure control and improved ear canal cleaning effectiveness, facilitating the doctor's diagnosis and treatment. Alternatively, a head clamp can be used to secure the rotary external auditory canal cleaner. First, the head clamp 19 is placed on the patient's head, such as... Figure 7 As shown, the ear clip 20 is then flipped outwards and fixed to the rotating external auditory canal cleaner via a snap-fit groove. The ear clip is then flipped downwards to allow the infusion tube to enter the ear canal for cleaning. Alternatively, the syringe and pressure balloon of Embodiment 3 can be used together to provide flexible pressure control for ear canal cleaning. Alternatively, Embodiment 4 can be used, where the drain valve 26 at the bottom of the liquid collection box is connected to the waste liquid tank 27 via a conduit. When a large amount of residual liquid is generated after cleaning, it is poured into the waste liquid tank 27 to complete the cleaning process.
[0029] In summary, the purpose of this utility model has been achieved.
