Description

Technical Field

[0001] The present invention relates to the field of medical technology, in particular to an ear washer and a method for using the same. Background Art

[0002] As we all know, an ear irrigator is a medical device used to clean the external auditory canal. It mainly flushes the ear canal with water at a specific pressure to help remove earwax, debris and foreign matter in the ear. It is usually composed of a liquid storage device, a catheter, an irrigator head and a pressure control component. It can be used with normal saline, special irrigating fluid, etc. This device is widely used in clinical diagnosis and treatment of otolaryngology and home care scenarios. Through the action of gentle water flow, it can clean the ear canal while avoiding damage to the ear canal skin and eardrum, providing a convenient tool for maintaining ear health. It is an important auxiliary equipment for traditional ear canal cleaning methods.

[0003] After searching, a Chinese patent discloses an ear irrigation device, and its application publication number is: CN100531811C. The patent provides an ear irrigation device for injecting fluid into the external auditory canal extending between the external ear and the eardrum, and the external auditory canal includes an external part extending inward from the external ear and having earwax-producing glands and an internal part between the eardrum and the external part. The ear irrigation device has a longitudinally extending main body including an inward end and an outward end. The ear irrigation device also includes an input pipe extending from the outward end to the inward end and terminating in a nozzle, and the nozzle is suitable for directing the fluid laterally and out of the main body toward the external ear when the inward end is placed close to the internal part of the external auditory canal.

[0004] When flushing the ears and external auditory canals, ear flusher equipment is used. The problems with the existing technology are: due to the lack of a structure for flushing the ear surface in multiple directions, the ear surface cannot be flushed in multiple directions at the same time, which reduces the flexibility when cleaning the ear surface; and there is a lack of a real-time recovery structure for waste liquid after flushing the ear, so the waste liquid after ear cleaning cannot be recovered in real time, which reduces the flexibility when cleaning the ear. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides an ear flusher and a method of using the same. The ear flusher has a structure for flushing the ear surface in multiple directions, so the ear surface can be flushed in multiple directions at the same time, thereby improving the flexibility of cleaning the ear surface. The ear flusher also has a structure for real-time recovery of waste liquid after ear flushing, so the waste liquid after ear cleaning can be recovered in real time, thereby improving the flexibility of ear cleaning.

[0007] (2) Technical solution

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: an ear flusher, comprising a cleaning mechanism and a drainage mechanism, the drainage mechanism being arranged on the front side of the cleaning mechanism, the cleaning mechanism comprising a limiting assembly, a guiding assembly, a spraying assembly, a positioning assembly and an adjusting assembly, the guiding assembly being arranged on the left side of the limiting assembly, the spraying assembly being arranged on the left side of the guiding assembly, the positioning assembly being arranged on the right side of the limiting assembly, and the adjusting assembly being arranged on the right side of the positioning assembly, the drainage mechanism comprising a conveying assembly, a connecting assembly and a pressure assembly, the conveying assembly being respectively arranged on the right side of the guiding assembly and the right side of the limiting assembly, the connecting assembly being arranged on the front side of the conveying assembly, and the pressure assembly being respectively arranged on the front side of the conveying assembly and the rear side of the connecting assembly.

[0009] By adopting the above technical solution, a cleaning mechanism and a drainage mechanism are set up. The drainage mechanism can be externally connected to a cleaning liquid storage device and a waste liquid recovery device to deliver the cleaning liquid to the cleaning mechanism, and the waste liquid in the cleaning mechanism is delivered to the waste liquid recovery device. The cleaning mechanism can spray the cleaning liquid into the user's ears as the pressure increases, thereby spraying and cleaning the user's ear surface at multiple angles.

[0010] The present invention is further configured as follows: the limiting assembly includes a positioning ring, a diverter groove and a protective cover, the diverter groove is opened on the inner side of the positioning ring, and the protective cover is fixedly connected to the surface of the positioning ring.

[0011] By adopting the above technical solution, by setting a limit component, the positioning ring can cooperate with the diverter groove and the protective cover, and a hollow annular fluid conveying structure is formed by the diverter groove and the positioning ring. The cleaning liquid conveyed by the conveying component can be conveyed to the spray component, and the protective cover and the positioning component can be supported and limited respectively by its own annular structure. The protective cover can cover the skin around the user's ears, thereby preventing the cleaning liquid from splashing around when cleaning the user's ears.

[0012] The present invention is further configured as follows: the guide assembly includes a drainage ring, a guide tube and an elastic cover, the drainage ring is fixedly connected to the front side of the protective cover, the guide tube is connected to the front side of the drainage ring, and the elastic cover is fixedly connected to the rear side of the drainage ring.

[0013] By adopting the above technical solution, by setting up a guide component, the drainage ring can cooperate with the guide tube and the elastic cover, and the guide tube and the elastic cover are limited by the drainage ring, which can increase the sealing of the protective cover when in contact with the user's skin after contact with the user's skin, and can utilize its own annular structure. When the guide tube is at the bottom of the drainage ring perpendicular to the ground, the cleaned waste liquid can be collected at the guide tube, so that the guide tube can send the waste liquid to the conveying component for recycling. The elastic cover is an existing cover-like structure with a built-in pipe and made of flexible elastic material. When the environment inside the protective cover is negative pressure, the elastic cover will open with the external pressure due to the negative pressure, and send the external gas into the protective cover, so as to avoid the user's skin being adsorbed by the negative pressure inside the protective cover and causing discomfort, and at the same time, it can also avoid the waste liquid being unable to flow from the guide tube to the conveying component due to negative pressure.

[0014] The present invention is further configured as follows: the spray assembly includes a diverter pipe, a limiting plate and a cleaning nozzle, the diverter pipe is connected to the surface of the positioning ring, the limiting plate is fixedly connected to the surface of the diverter pipe, and the cleaning nozzle is connected to the right side of the diverter pipe.

[0015] By adopting the above technical solution, through setting up a spray assembly, the diverter pipe can cooperate with the limit plate and the cleaning nozzle. The limit plate can limit the diverter pipe to the inner wall of the protective cover to adapt to the shape of the inner wall of the protective cover. The cleaning liquid transported in the positioning ring is guided to each cleaning nozzle through the diverter pipe, so that each cleaning nozzle can spray the cleaning liquid onto the user's ear. Since the diverter pipe is a structure with multiple arc shapes covering the ear, the cleaning nozzles evenly distributed on its surface can also flush the surface of the ear from multiple angles and multiple directions, thereby improving the flexibility of cleaning the ear.

[0016] The present invention is further configured as follows: the positioning assembly includes a pressure tube, a pressure piston and a blocking sleeve, the pressure tube is connected to the right side of the positioning ring, the pressure piston is slidably connected to the inner side of the pressure tube, and the blocking sleeve is connected to the left side of the pressure tube.

[0017] By adopting the above technical solution, by setting a positioning component, the pressure tube can cooperate with the pressure piston and the blocking sleeve. The pressure piston moves in the pressure tube as the adjustment component moves, so that the gas content in the pressure tube can be changed, so that the gas in the pressure tube can be sent to the blocking sleeve. The blocking sleeve is a tubular structure made of flexible material, which can expand when the gas is filled inside to increase the pressure. Therefore, it can block the user's ear canal when placed in the user's ear canal.

[0018] The present invention is further configured as follows: the adjusting assembly includes a threaded barrel, an adjusting screw and an adjusting cover, the threaded barrel is connected to the right side of the pressure tube, the adjusting screw is threadedly connected to the inner side of the threaded barrel, the left side of the adjusting screw is rotatably connected to the right side of the pressure piston, and the adjusting cover is fixedly connected to the right side of the adjusting screw.

[0019] By adopting the above technical solution, through setting up an adjustment component, the threaded barrel can cooperate with the adjusting screw and the adjusting cover. By forming an adjustment structure with the adjusting cover, the adjusting screw and the threaded barrel, the user can make the adjusting screw move in the thread of the threaded barrel when turning the adjusting cover, thereby changing the orientation of the pressure piston when the adjusting screw thread moves, and providing the pressure piston with the power required for movement.

[0020] The present invention is further configured as follows: the conveying assembly includes a conveying pipe, a conveying one-way valve, a recovery pipe and a recovery one-way valve, the conveying pipe is connected to the right side of the positioning ring, the conveying one-way valve is connected to the front side of the conveying pipe, the recovery pipe is connected to the right side of the guide pipe, and the recovery one-way valve is connected to the front side of the recovery pipe.

[0021] By adopting the above technical solution, by setting up a conveying component, the conveying pipe can be connected with the conveying one-way valve, the recovery pipe and the recovery one-way valve. The conveying pipe can form a one-way channel with the conveying one-way valve to convey the fluid to the positioning ring, and the cleaning liquid can be conveyed to the diversion groove in the positioning ring. The recovery pipe can form a one-way channel with the recovery one-way valve to convey the fluid to the pressure component, and the waste liquid at the guide pipe can be conveyed into the guide pipe.

[0022] The present invention is further configured as follows: the connecting assembly includes a connecting frame, an input one-way valve, an input pipe, an output one-way valve and an output pipe, the connecting frame is fixedly connected to the surface of the delivery one-way valve and the surface of the recovery one-way valve respectively, the input one-way valve is fixedly connected to the side of the connecting frame away from the delivery one-way valve, the input pipe is connected to the side of the input one-way valve away from the delivery one-way valve, the output one-way valve is fixedly connected to the side of the connecting frame away from the recovery one-way valve, and the output pipe is connected to the side of the output one-way valve away from the recovery one-way valve.

[0023] By adopting the above technical solution, by setting up a connecting component, the connecting frame can cooperate with the input one-way valve, input pipe, output one-way valve and output pipe. The connecting frame can use the delivery one-way valve and the recovery one-way valve as support points to limit the input one-way valve and the output one-way valve, so that the delivery one-way valve and the input one-way valve can be on the same horizontal line, and the output one-way valve and the recovery one-way valve can be on the same horizontal line, so that when the input one-way valve is connected to the cleaning liquid storage device through the input pipe, the cleaning liquid is delivered to the delivery one-way valve through the pressure component, and the recovery one-way valve can deliver the waste liquid to the output one-way valve through the pressure component, and then deliver it to the waste liquid recovery device after the output pipe is connected to the waste liquid recovery device.

[0024] The present invention is further configured as follows: the pressure assembly includes a limiting ring, an airbag and a reset rubber band, the four limiting rings are respectively fixedly connected to the front side of the delivery one-way valve, the front side of the recovery one-way valve, the rear side of the input one-way valve and the rear side of the output one-way valve, the airbag is sleeved on the surface of the limiting ring, the reset rubber band is fixedly connected to the inner side of the limiting ring, and the surface of the reset rubber band is in contact with the inner side of the airbag.

[0025] By adopting the above technical solution, a pressure component is set up, and the limiting ring can cooperate with the airbag and the reset rubber band. By limiting the airbag and the reset rubber band by the limiting ring, the airbag can form a channel for fluid transportation. And because the airbag itself is made of flexible material, when the user holds the airbag tightly, the airbag can send the internal fluid to the delivery one-way valve and the output one-way valve respectively. The reset rubber band can use its own elastic force to reset the airbag when it is no longer subjected to external force. Negative pressure will be generated inside the airbag due to the reset, thereby sucking the fluid at the input one-way valve and the recovery one-way valve into the airbag, thereby achieving the fluid transportation effect.

[0026] A method for using an ear washer comprises the following steps:

[0027] S1. Supply of cleaning liquid and comprehensive cleaning of the ear surface: First, place the blocking sleeve into the user's ear canal, then place the protective cover on the skin around the user's ear until the drainage ring fits the skin, then turn the adjusting cover to allow the adjusting cover to drive the adjusting screw in the threaded barrel to move the pressure piston in the pressure tube toward the blocking sleeve, thereby pushing the gas in the pressure tube toward the blocking sleeve. The blocking sleeve will expand as the gas is filled until the user's ear canal is blocked, and the input tube is connected to the cleaning liquid storage device. Then, the delivery tube is connected to the positioning ring, and then the recovery tube is connected to the guide tube. At this time, squeeze each air bag, and then release each air bag. The air bag will generate negative pressure under the reset of the reset rubber band, thereby sucking the cleaning liquid storage device connected to the input tube into the current air bag, and then the cleaning liquid will flow from the diversion groove in the positioning ring into each diversion tube respectively, and then be sprayed to the user's ear through the cleaning nozzle to rinse and clean the user's ear. The cleaned waste liquid will flow along the protective cover to the guide tube;

[0028] S2. Waste liquid recovery: First, connect the output tube to the waste liquid recovery equipment. At this time, squeeze each airbag, and then release each airbag. Another airbag will recycle the waste liquid in the recovery tube into the airbag through the recovery one-way valve. Then squeeze each airbag again. The airbag will transport the internal cleaning liquid from the delivery tube to the positioning ring through the delivery one-way valve. The waste liquid will be sent from the output tube to the waste liquid storage equipment through the output one-way valve.

[0029] (3) Beneficial effects

[0030] Compared with the prior art, the present invention provides an ear washer and a method of using the same, which have the following beneficial effects:

[0031] The ear irrigator is provided with a cleaning mechanism, a limiting component that can cooperate with a guiding component, a spraying component, a positioning component and an adjusting component. The limiting component and the guiding component are covered on the skin near the user's ear, thereby providing a temporary closed environment for the user's ear, temporarily guiding the waste liquid generated during cleaning, and directing the waste liquid to the drainage mechanism for recovery. The fluid delivery channel formed by the limiting component and the spraying component can allow the spraying component to spray the cleaning liquid onto the user's ear surface at multiple angles and directions when the drainage mechanism delivers the cleaning liquid into the spraying component, thereby performing multi-directional and multi-angle flushing and cleaning on the user's ear. The limiting structure formed by the positioning component and the adjusting component allows the positioning component to block the user's ear canal by adjusting the pressure inside the positioning component through the adjusting component when the positioning component is placed in the user's ear canal, thereby preventing the cleaning liquid from entering the user's ear canal during cleaning and causing an impact.

[0032] The ear flusher is provided with a drainage mechanism, and the conveying component can form a fluid conveying channel with the connecting component and the pressure component. The connecting component is respectively connected to the cleaning liquid conveying equipment and the waste liquid recovery equipment. The conveying component can be respectively connected to the waste liquid conveying end and the cleaning liquid input end of the cleaning liquid. When the pressure component is squeezed by an external force and released, the negative pressure of the pressure component itself can be used to suck the cleaning liquid at the connecting component into the pressure component, and the waste liquid in the cleaning mechanism can be recovered into the pressure component. Therefore, when the pressure component is squeezed again, the pressure component can convey the cleaning liquid to the cleaning liquid input end in the cleaning mechanism through the conveying component, and convey the waste liquid to the waste liquid recovery device through the connecting component.

The output pipe 225 is connected to the side of the output one-way valve 224 away from the recovery one-way valve 214. By setting the connecting component 22, the connecting frame 221 can be connected to the input one-way valve 222, the input pipe 223 and the output one-way valve 224. 23. The output one-way valve 224 and the output pipe 225 cooperate, and the connecting frame 221 can limit the input one-way valve 222 and the output one-way valve 224 with the delivery one-way valve 212 and the recovery one-way valve 214 as support points, so that the delivery one-way valve 212 and the input one-way valve 222 can be on the same horizontal line, and the output one-way valve 224 and the recovery one-way valve 214 can be on the same horizontal line, so that when the input one-way valve 222 is connected to the cleaning liquid storage device through the input pipe 223, the cleaning liquid is delivered to the delivery one-way valve 212 through the pressure component 23, and the recovery one-way valve 214 delivers the waste liquid to the output one-way valve 224 through the pressure component 23, and delivers it to the waste liquid recovery device after the output pipe 225 is connected to the waste liquid recovery device.

[0059] Among them, the pressure component 23 includes a limiting ring 231, an airbag 232 and a reset rubber band 233. The four limiting rings 231 are respectively fixedly connected to the front side of the delivery one-way valve 212, the front side of the recovery one-way valve 214, the rear side of the input one-way valve 222 and the rear side of the output one-way valve 224. The airbag 232 is sleeved on the surface of the limiting ring 231, and the reset rubber band 233 is fixedly connected to the inner side of the limiting ring 231. The surface of the reset rubber band 233 contacts the inner side of the airbag 232. By setting the pressure component 23, the limiting ring 231 can cooperate with the airbag 232 and the reset rubber band 233, and the airbag 232 and the reset rubber band 233 are adjusted by the limiting ring 231. The airbag 232 and the reset rubber band 233 are limited, so that the airbag 232 can form a channel for fluid transportation. Moreover, since the airbag 232 itself is made of flexible material, when the user holds the airbag 232 tightly, the airbag 232 can respectively send the internal fluid to the delivery one-way valve 212 and the output one-way valve 224. The reset rubber band 233 can use its own elastic force to reset the airbag 232 when it is no longer subjected to external force. The interior of the airbag 232 will generate negative pressure due to the reset, thereby sucking the fluid at the input one-way valve 222 and the recovery one-way valve 214 into the airbag 232, thereby achieving the fluid transportation effect.

[0060] The working principle of this embodiment is as follows: first, the output tube 225 is connected to the waste liquid recovery device, and the input tube 223 is connected to the cleaning liquid storage device. Then, the delivery tube 211 is connected to the cleaning mechanism 1, and then the recovery tube 213 is connected to the cleaning mechanism 1. At this time, each airbag 232 is squeezed, and then each airbag 232 is released. The airbag 232 will generate negative pressure under the reset of the reset rubber band 233, thereby sucking the cleaning liquid storage device connected to the input tube 223 into the current airbag 232, and the other airbag 232 will recycle the waste liquid at the recovery tube 213 into the airbag 232 through the recovery one-way valve 214. Then, each airbag 232 is squeezed again, and the airbag 232 will transport the internal cleaning liquid from the delivery tube 211 to the cleaning mechanism 1 through the delivery one-way valve 212. The waste liquid will be sent from the output tube 225 to the waste liquid storage device through the output one-way valve 224.
