Description

Technical Field

[0001] The present application relates to the technical field of ear canal cleaning, and in particular to an isolated automatic ear canal cleaning device. Background Art

[0002] Preoperative preparation is very important for external auditory canal and middle ear surgery. Because there are secretions or other pathological tissues in the external auditory canal when the external auditory canal and middle ear are diseased, it is particularly critical to conduct preoperative preparation on the premise of understanding the lesions to prevent adverse consequences caused by bleeding or shedding of diseased tissue due to pulling and irritating the diseased tissue. Therefore, ear canal cleaning is an extremely important part of preoperative preparation. Existing ear canal cleaning devices mainly include scraping, flushing and negative pressure suction. The direct contact scraping method has a good cleaning effect, but it is easy to cause damage to the external auditory canal; the flushing method uses a medicine that can soften the secretions to flush the ear canal; the pure flushing method is better for smaller and more viscous secretions, but it is not effective for oily or larger secretions. The negative pressure suction method uses a straw to suck out the secretions, which is time-consuming and laborious to operate due to the poor visual effect of the ear canal.

[0003] For example, in the existing Chinese patent with the publication number CN211095243U, an ear canal cleaning device is disclosed, which includes a handle and a cleaning rod, a battery and a rotating motor are arranged inside the handle, the output end of the rotating motor is connected to a rotating seat, an adjusting rod is connected to the inside of one side of the rotating seat through a bearing, a screw is connected to the inside of one end of the cleaning rod through a bearing, a cross telescopic rod is sleeved on the outside of the screw, a through groove is opened on the outside of the cleaning rod, a push-pull rod is connected to the inside of the through groove through a rotating shaft, and a cleaning cotton ball is sleeved on the outside of the push-pull rod. Through the existing technology, when in use, the cleaning cotton ball sleeved at the end of the push-pull rod is conveniently folded into the patient's ear and opened outward by opening and closing the push-pull rod, so as to adapt to the different sizes of the ear canals of different patients, so that the cleaning cotton ball is fully in contact with the patient's ear canal, and the cleaning is achieved by rotating.

[0004] However, the above prior art has the following technical defects:

[0005] First, the above-mentioned prior art cleans the ear canal by scraping it in direct contact with the ear canal. The cleaning method is relatively simple. When it is necessary to inject medicine into the ear canal to clean the secretions, the above-mentioned prior art cannot effectively protect the middle ear and the inner ear to prevent the medicine from entering the deep ear canal and causing damage to the inside of the ear canal when it is injected into the ear canal.

[0006] Secondly, the above-mentioned prior art is not provided with a corresponding safety protection device. When using the above-mentioned device, it is first necessary to hold the handle and push the cleaning rod into the patient's ear. During this process, it is easy for the cleaning rod to extend too deep into the patient's ear canal. Improper use can easily cause damage to the ear canal.

[0007] Based on this, on the basis of the existing ear canal cleaning device, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-11 This application is described in further detail.

[0036] The embodiment of the present application discloses an isolated automatic ear canal cleaning device, which can prevent the ear canal from being damaged by the medicine used to clean the ear canal, and can also avoid the ear canal from being damaged by improper use. The present application provides an isolated automatic ear canal cleaning device, including an ear canal model 1, on which a cleaning device 11 for cleaning the ear canal is placed, which can be used as follows when in use. Figure 1 As shown in the figure, part of the cleaning mechanism of the cleaning device 11 is inserted into the ear canal, and a part is left in the external auditory canal and is in close contact with the external auditory canal. Then the ear canal can be scraped and cleaned by injecting medicine.

[0037] Reference Figure 1 and Figure 2As shown, the cleaning device 11 extends into the ear canal model 1, and a protective limiting strip 12 for safety protection is placed at the outer ear of the ear canal model 1. An outer rod 13 for extending into the ear canal is slidably provided on the protective limiting strip 12. It should be noted that the portion of the protective limiting strip 12 that conflicts with the external ear canal is made of soft rubber material, and the outer rod 13 is also made of rubber material and can be bent to a certain extent, thereby avoiding damage to the ear canal when the device is used to clean the ear canal; a sliding hole 121 is provided through the protective limiting strip 12 for the outer rod 13 to slide through, and a clamping mechanism 2 for fixing and limiting the outer rod 13 and a cleaning mechanism 3 connected to the outer rod 13 for cleaning the ear canal are provided on the protective limiting strip 12, and a protective mechanism 4 for isolating the deep part of the ear canal and a scraping mechanism 5 for cleaning the ear canal are provided on the outer rod 13.

[0038] When the ear canal needs to be cleaned, first slowly insert the outer rod 13 into the ear canal to a certain position, adjust the protective limiting strip 12 to make it contact with the external auditory canal, and use the clamping mechanism 2 to clamp and fix the protective limiting strip 12 and the outer rod 13. Then, open the protective mechanism 4 to stabilize the outer rod 13 extending into one end of the ear canal, and prevent the medicine from entering the deep ear canal and causing damage to the ear canal when the medicine is used to clean the ear canal. Then, start the scraping mechanism 5 to effectively scrape the secretions in the ear canal. At the same time, the scraping mechanism 5 can cooperate with the cleaning mechanism 3. When scraping the secretions in the ear canal, the cleaning mechanism 3 can inject medicine into the ear canal to clean the ear canal at the same time.

[0039] Reference Figure 3As shown, since the ear canals of each user are different, the protective limiting strip 12 and the outer rod 13 need to be adjusted accordingly to achieve the best use effect. The clamping mechanism 2 includes a sliding seat 21, a limiting recess 12, a limiting recess 23, a first tightening spring 24, a second tightening spring 25 and a release button 26; the two sliding seats 21 are respectively fixedly mounted on the protective limiting strip 12 located at the upper and lower sides of the sliding hole 121, and the protective limiting strip 12 is provided with a sliding hole 121 for sliding. The square groove 122 of the seat 21 is installed, and the sliding hole 121 is located in the middle of the square groove 122, that is, the part of the outer rod 13 inserted into the sliding hole 121 is located in the middle of the square groove 122; the limiting concave block 1 22 and the limiting concave block 23 are respectively slidably arranged between the two sliding seats 21, and are respectively located on both sides of the outer rod 13. It should be noted that the sliding seat 21 is set in a "mountain" shape, and the limiting concave block 1 22 and the limiting concave block 23 are respectively slidably arranged at the two recesses of the sliding seat 21; one end of the first tightening spring 24 The first pressing spring 24 is fixedly arranged on the side wall of the square groove 122, and the other end is fixedly connected to the limiting concave block 1 22. The first pressing spring 24 always has a driving force to push the limiting concave block 1 22 toward the outer rod 13. The second pressing spring 25 is fixedly arranged on the side wall of the square groove 122 away from the first pressing spring 24, and the other end is fixedly connected to the limiting concave block 23. The second pressing spring 25 always has a driving force to push the limiting concave block 23 toward the outer rod 13, thereby realizing the first pressing spring 24 and the second pressing spring 25. The two clamping springs 25 exert a pushing force on the limiting recess 1 22 and the limiting recess 23, so that the limiting recess 1 22 and the limiting recess 23 always have a clamping force on the outer rod 13 in the square groove 122; the two release buttons 26 are respectively slidably inserted on both sides of the protection limit strip 12, and the insertion ends of the two release buttons 26 are respectively fixedly connected to the limiting recess 1 22 and the limiting recess 23, and the protection limit strip 12 is provided with an insertion hole 123 which is connected to the square groove 122 for the release button 26 to be slidably inserted.

[0040] When in use, first press the two release buttons 26 into the protection limit strip 12 to release the clamping force of the limit recess 1 22 and the limit recess 2 23 on the outer rod 13, then adjust the depth of the outer rod 13 entering the ear canal according to one's own situation, and make the protection limit strip 12 touch the external auditory canal. After adjustment, release the two release buttons 26, and the limit recess 1 22 and the limit recess 2 23 will have the clamping force on the outer rod 13 again, thereby achieving the effect of clamping and fixing the outer rod 13.

[0041] Reference Figure 4As shown, in order to prevent the medicine from entering the deep part of the ear canal and causing damage to the ear canal when the medicine is used to clean the ear canal, and at the same time to firmly press the outer rod 13 at one end extending into the ear canal, the protection mechanism 4 includes a pushing rod 41, a base disc 42, an outer round block 43, a protection airbag 44 and a pusher 6; the pushing rod 41 is slidably inserted into the outer rod 13, and an insertion groove 131 for sliding the pushing rod 41 is opened on the outer rod 13. The base disc 42 is fixedly arranged at the end of the outer rod 13 away from the protection limit strip 12, that is, installed at the end of the outer rod 13 extending into the ear canal; the outer round block 43 is fixedly arranged at the far end of the base disc 42 through a hollow hole column 45 On the side away from the outer rod 13, the inner cavity of the hollow hole column 45 is connected with the insertion groove 131, and the base disc 42 and the outer rod 13 are both provided with a connecting hole 421, through which the insertion groove 131 on the outer rod 13 is connected with the inner cavity of the hollow hole column 45; the protective airbag 44 is arranged between the base disc 42 and the outer round block 43, and a plurality of air supply holes 451 connected with the inner cavity of the protective airbag 44 are arranged on the hollow hole column 45. Because the inner cavity of the hollow hole column 45 is connected with the insertion groove 131, the inner cavity of the protective airbag 44 is connected with the insertion groove 131 through the air supply holes 451; the pusher 6 is arranged on the pushing round rod 41, and is used to inflate the protective airbag 44.

[0042] After the outer rod 13 is clamped and secured by the clamping mechanism 2, the protective mechanism 4 is started to push the pushing round rod 41 into the insertion groove 131, that is, into the ear canal to drive the pusher 6 to deliver air into the protective airbag 44. Finally, the protective airbag 44 expands to fit tightly against the inner wall of the ear canal, thereby isolating the deep part of the ear canal from the outside world, preventing the medicine from entering the deep part of the ear canal, and firmly fixing the outer rod 13 in the ear canal.

[0043] Continue to refer to Figure 4 As shown, it is a schematic diagram of the structure of the pusher 6 in this embodiment, and the pusher 6 includes a pushing button 61, a pushing column 62, an air supply rubber 63, a fan-shaped locking block 64 and a limiting half block 65; the pushing button 61 is fixedly sleeved on the end of the pushing rod 41 away from the base disc 42, the pushing column 62 is fixedly arranged on the end of the pushing rod 41 away from the pushing button 61 and is located in the insertion groove 131, the air supply rubber 63 is fixedly arranged on the end of the pushing column 62 away from the pushing rod 41, and the fan-shaped locking block 64 is fixedly installed on the pushing column 62 near the pushing rod 41. In this embodiment, preferably, seven limiting half blocks 65 are equidistantly fixed on the inner wall of the insertion groove 131 between the pushing rod 41 and the air supply rubber 63.

[0044] Because the inner cavity of the protective airbag 44 is connected to the insertion groove 131, when the pushing rod 41 is pushed into the ear canal, the air supply rubber 63 can be driven to transport the air in the insertion groove 131 to the protective airbag 44. When the protective airbag 44 expands to fit tightly against the inner wall of the ear canal, the pushing rod 41 can be rotated 180 degrees to allow the fan-shaped locking block 64 set on the pushing column 62 to be stuck between the limiting half blocks 65, so as to achieve the effect of locking the pushing rod 41, so that the protective airbag 44 is always in an expanded state and fits tightly against the inner wall of the ear canal.

[0045] Reference Figure 5 and Figure 6 As shown, since it is necessary to effectively scrape the secretions attached to the inner wall of the ear canal, the scraping mechanism 5 includes a pull-out rod 51, a pull-out round button 52, an expansion disc 53, a fixing block 54 and an expander 7; the pull-out rod 51 is slidably inserted in the push round rod 41, and it should be noted that there is a certain damping when the pull-out rod 51 is slidably inserted in the push round rod 41; the push round rod 41 is provided with a pull-out groove 411 for the pull-out rod 51 to be slidably inserted, the pull-out round button 52 is fixedly sleeved on one end of the pull-out rod 51 close to the push button 61, and the expansion disc 53 is slidably sleeved on the outer rod 13 close to the base disc 42, That is, when the outer rod 13 is extended into the ear canal, the expansion disc 53 also enters the ear canal; one end of the two fixing blocks 54 is respectively fixedly installed on the inner ring wall of the expansion disc 53, and the other end extends into the outer rod 13 and is fixedly connected to the pull rod 51. The outer rod 13 and the pushing rod 41 are both provided with a penetration slot 132 for the fixing blocks 54 to extend and penetrate. When the pull rod 51 is subjected to a driving force, the fixing block 54 can be driven to slide on the penetration slot 132, that is, the expansion disc 53 can be driven to slide on the outer rod 13; the expander 7 is arranged on the outer rod 13 and can cooperate with the pull rod 51 and the expansion disc 53 to clean the ear canal.

[0046] Reference Figure 6 and Figure 7As shown, in order to be suitable for most people and to be able to adjust to the width of each person's ear canal according to the different widths of each person's ear canal, so as to ensure that the secretions on the inner wall of the ear canal can be effectively scraped, the expander 7 includes a disc seat 71, a device ring 72, a scraping fan 73, a closing spring 74 and an adjusting member 8; the disc seat 71 is slidably mounted on the outer rod 13 between the expansion disc 53 and the base disc 42, and the device ring 72 is fixedly arranged on the outer circumference of the disc seat 71 by a plurality of curved solid blocks 75. It should be noted that in this embodiment, preferably four scraping fan blades 73 are equidistantly movably mounted on the device ring 72. In this embodiment, preferably, there are four closing springs 74, which are the same as the number of scraping fan blades 73. One end of the closing spring 74 is fixedly mounted on the expansion disc 53 toward the disc seat 7 One end of the four closing springs 74 is fixedly mounted on the expansion disk 53 at equal intervals, and the other end is fixedly connected to the corresponding and closest scraping blades 73, and always has a pulling force to pull the scraping blades 73 in the direction of the expansion disk 53, that is, the four scraping blades 73 are always closed on the outer circumferential surface of the expansion disk 53 without the driving of external force; the adjusting member 8 is arranged in the pulling rod 51 to adjust the expansion angle of the scraping blades 73; after the expansion angle of the scraping blades 73 is adjusted by the adjusting member 8, that is, the four scraping blades 73 are expanded and abutted against the inner wall of the ear canal, and then the pulling rod 51 is repeatedly pulled outward and pushed inward, the scraping blades 73 can be driven to effectively scrape the secretions attached to the inner wall of the ear canal.

[0047] Reference Figure 7 and Figure 88, which is a schematic diagram of the structure of the adjusting member 8 in this embodiment. The adjusting member 8 includes a rotating screw 81, a rotating nut 82, a cylindrical rod 83, a limiting ring 84, a rotating ring 85 and a long solid block 86; the rotating screw 81 is rotatably arranged in the pull rod 51, and a rotating groove 511 for rotating the rotating screw 81 is threadedly opened on the pull rod 51, and the rotating nut 82 is fixedly sleeved on the rotating screw 81 near one end of the pull round button 52, and the cylindrical rod 83 is fixedly installed on the end of the rotating screw 81 away from the rotating nut 82 and is in the rotating groove 511, two limiting rings 84 are fixedly sleeved on the cylindrical rod 83, and the rotating ring 85 is rotatably arranged between the two limiting rings 84. On the column rod 83, one end of the two long solid blocks 86 is fixedly mounted on the inner ring wall of the disc seat 71, and the other end extends into the outer rod 13 and is fixedly connected to the rotating ring 85, so that when the rotating screw 81 is subjected to force and rotates, it will not be restricted by the long solid blocks 86 and the disc seat 71. At the same time, when the rotating screw 81 rotates and extends outward, the long solid blocks 86 and the disc seat 71 can be synchronously driven to move outward, that is, the disc seat 71 can be driven to slide on the outer rod 13 toward the expansion disc 53; the outer rod 13, the pushing round rod 41 and the pulling rod 51 are all provided with sliding long grooves 133 for the long solid blocks 86 to extend and penetrate and communicate with the penetrating long grooves 132.

[0048] When in use, first, the rotating screw 81 can be driven to rotate by turning the nut 82 to drive the disc seat 71 to slide in the direction of the expansion disc 53. At the same time, the scraping fan 73 movably mounted on the device ring 72 will expand outward due to the smaller distance between the disc seat 71 and the expansion disc 53 until the scraping fan 73 conflicts with the inner wall of the ear canal. It should be noted that the part of the scraping fan 73 that conflicts with the inner wall of the ear canal is made of rubber and will not cause damage to the inner wall of the ear canal. Then, the rotating screw 81 stops rotating, that is, the scraping fan 73 can always maintain the current expanded state of conflicting with the inner wall of the ear canal. Finally, the scraping fan 73 is driven by repeatedly pulling the pulling rod 51 outward and pushing the pulling rod 51 inward to repeatedly scrape the ear canal. At this time, one end of the outer rod 13 in the ear canal is blocked by the protective film. The protective mechanism 4 is temporarily secured in the ear canal, so the pull-out rod 51 can be smoothly pulled outwards; it should be noted that the outer rod 13, the pushing round rod 41, the pull-out rod 51 and the rotating screw 81 are all made of rubber materials of different hardness and can be bent to a certain extent. When the scraping blade 73 is driven to the narrow position of the ear canal by force, the scraping blade 73 itself is also made of rubber material at the point where it contacts the inner wall of the ear canal and can be bent. The bending of the outer rod 13, the pushing round rod 41, the pull-out rod 51 and the rotating screw 81 can enable the scraping blade 73 to smoothly pass through the narrow part of the inner wall of the ear canal; because of the action of the closing spring 74, when the pull-out rod 51 is pulled outwards to drive the scraping blade 73 to scrape the inner wall of the ear canal, the scraping blade 73 will always maintain the previously adjusted expansion angle and will not change.

[0049] Reference Figures 9 to 11 As shown in the figure, since it is necessary to clean the ear canal again with medicine or other liquids, the cleaning mechanism 3 includes a rectangular rubber pad 31, a downward pressure spring 32, a sealing plate 33, a liquid delivery tube 34, a closed ring column 35, a connecting ring rod 36, a ring pull rope 37 and a water injection knob 38; the rectangular rubber pad 31 is slidably arranged in the protection limit strip 12 above the square groove 122, and the protection limit strip 12 is provided with a water injection groove 124 for installing the rectangular rubber pad 31, and one end of the two downward pressure springs 32 is connected to the rectangular rubber pad 3 1, and the other end is fixedly connected to the top wall of the water injection groove 124 extending upward and above, and the two downward pressure springs 32 always have the driving force to push the rectangular rubber pad 31 downward; the sealing plate 33 is sealed and covered on the water injection groove 124, and the sealing plate 33 is provided with a water injection hole 331 for liquid injection, one end of the two liquid delivery pipes 34 is connected to the sealing plate 33, and the other end is respectively connected to the two sides of the outer rod 13, and the side wall of the outer rod 13 is respectively provided with two liquid delivery pipes 34 for liquid delivery The outer rod 13 is provided with a plurality of spray holes 135 connected to the infusion pipe 134 for spraying liquid near the base disc 42. The closed ring column 35 is slidably sleeved on the outer rod 13 and is located at the spray hole 135. The initial position of the closed ring column 35 is at the spray hole 135. At this time, the closed ring column 35 can close the spray hole 135, and the liquid in the protective limiting strip 12 cannot be discharged through the spray hole 135. Two connecting ring rods 36 are provided between the closed ring column 35 and The disc seat 71 is between them, and the two ends of the connecting ring rod 36 are fixedly connected to the closed ring column 35 and the disc seat 71 respectively. When the disc seat 71 is forced to move, the closed ring column 35 can be synchronously driven to slide on the outer rod 13; one end of the ring pull rope 37 is fixedly connected to the rectangular rubber pad 31, and the other end penetrates the protection limit strip 12 and extends outward. A pull rope hole 125 for the ring pull rope 37 to penetrate is opened on the protection limit strip 12, and the water injection knob 38 is rotatably installed at the water injection hole 331 on the sealing plate 33.

[0050] In actual use, the downward pressure spring 32 always has a driving force to push the rectangular rubber pad 31 downward, and when the disc seat 71 is driven to move to scrape the inner wall of the ear canal, the closed ring column 35 can be synchronously driven to slide on the outer rod 13. When the closed ring column 35 is forced to move and is no longer at the position of the spray hole 135, the liquid in the protection limit strip 12 enters the liquid delivery pipe 134 through the liquid delivery pipe 34 under the action of the downward pressure spring 32, and finally the liquid is discharged from the spray hole 135. The liquid is sprayed into the ear canal to achieve the effect of cleaning the ear canal again with liquid. When the liquid in the protection limiting strip 12 is used up, it is necessary to pull the ring pull rope 37 outward to drive the rectangular rubber pad 31 to move up to the highest point, and then turn on the water injection knob 38 to re-inject liquid into the water injection tank 124 through the water injection hole 331. It should be noted that the protection limiting strip 12 is not completely blocked at the ear hole, and the liquid injected into the ear canal and the secretions in the ear canal scraped by the scraping mechanism 5 can be smoothly discharged from the ear canal.

[0051] The implementation principle of this embodiment is:

[0052] (1) Length adjustment: First, insert the outer rod 13 into the ear canal, and the protective limiting strip 12 abuts against the outer ear canal. Then, press the two release buttons 26 inside the protective limiting strip 12 to release the clamping force on the outer rod 13. Pull and adjust the outer rod 13 to a suitable depth in the ear canal. After the depth of the outer rod 13 in the ear is adjusted, release the release button 26 so that the outer rod 13 is clamped and fixed again.

[0053] (2) Stable protection: The push rod 41 is then pushed toward the inner ear canal to drive the protective airbag 44 to expand until it is in close contact with the inner wall of the ear canal through the pusher 6, and then the push rod 41 is rotated 180 degrees to lock the push rod 41, that is, the protective airbag 44 is locked, so that the protective airbag 44 always remains inflated and in close contact with the inner wall of the ear canal, which can prevent liquids such as medicine from entering the deep ear canal, and can temporarily stabilize the end of the outer rod 13 in the ear canal to facilitate the subsequent cleaning operation of the ear canal;

[0054] (3) Scraping and cleaning: Then, the expansion device 7 installed in the scraping mechanism 5 cooperates with the expansion disk 53 to adjust the expansion angle of the scraping blade 73 to adapt to the width of the ear canal of different users. After the scraping blade 73 is adjusted, the pull rod 51 is repeatedly driven to move outward and inward to drive the scraping blade 73 to effectively scrape the secretions attached to the inner wall of the ear canal;

[0055] (4) Liquid cleaning: Finally, when the scraping mechanism 5 scrapes the secretions attached to the inner wall of the ear canal, the cleaning mechanism 3 can be synchronously driven to inject liquids such as medicine into the ear canal for secondary cleaning of the ear canal. The previous protective mechanism 4 has isolated the deep part of the ear canal from the outside world and stabilized one end of the outer rod 13 in the ear canal, so that the liquid will not enter the ear canal deeply and cause damage to the ear canal. At the same time, the pull rod 51 can be repeatedly pushed and pulled.

[0056] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
