Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an external auditory canal cleaner. BACKGROUND

[0002] External auditory canal flushing is a common treatment technique in otolaryngology, which is used to remove cerumen, cerumen, foreign bodies and the like in the external auditory canal.

[0003] The external auditory canal is an "S" shaped curved channel from the external auditory meatus to the tympanic membrane, 2.5-3.5 cm long, from the outside to the inside, the external auditory canal first tends to be forward and upward, then turns to the back, and finally to the front and downward, the outer 1 / 3 of the external auditory canal is the cartilage part, which is continuous with the soft tube of the auricle; the inner 2 / 3 is the bony part, which is an elliptical short tube surrounded by the squamous part and the tympanic part of the temporal bone. Because the cartilage part can be moved by pulling the auricle, when checking the external auditory canal and the tympanic membrane, the auricle is pulled upward and backward, which can make the external auditory canal straight. The external auditory canal of infants is almost entirely supported by cartilage, short and straight, and the tympanic membrane is nearly horizontal. When checking, the auricle needs to be pulled downward and backward.

[0004] The surface of the external auditory canal is covered with a thin layer of skin, and the skin of the cartilage part contains a large number of sensory nerve endings, hair follicles, sebaceous glands and cerumen glands. The yellow-brown viscous material secreted by the cerumen gland is called cerumen, which can form a block after drying, which may block the external auditory canal and affect hearing. The subcutaneous tissue of the external auditory canal is very little, and the skin is closely connected with the soft tube membrane and the periosteum, which is not easy to move, so when the external auditory canal has a boil, it is very painful due to the large tension.

[0005] However, in the existing process of cleaning the external auditory canal, if the position of the entire cleaner is moved in the external auditory canal during cleaning, the hand of the medical staff holding the cleaner needs to be very stable and not to shake, and shaking or shaking will cause damage to the inner wall of the external auditory canal. The position of the cleaner needs to be stable during cleaning and not to shake, because the length of the external auditory canal of each person will be different, and in the process of use, children, adults or the elderly will be faced with different lengths of external auditory canal, and the position of the tool during cleaning will also be different. The existing external auditory canal cleaner cannot adjust the cleaning position and length according to the different lengths of the external auditory canal during cleaning, so that the user's external auditory canal can be cleaned comprehensively.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0041] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] This invention provides an external auditory canal cleaner, including a handle 1, an outer tube 2 at the front end of the handle 1, a sliding groove 21 on the outer tube 2, an occlusion airbag 3 at the front end of the outer tube 2, an occlusion moving structure 4 inside the handle 1, the occlusion moving structure 4 slidingly engaging with the handle 1, the occlusion moving structure 4 being connected to the occlusion airbag 3 and driving the occlusion airbag 3 to move within the external auditory canal, a cleaning adjustment structure 5 inside the handle 1, the cleaning adjustment structure 5 sliding within the sliding groove 21 on the outer tube 2, and the cleaning adjustment structure 5 slidingly engaging with the outer tube 2; a rotating cleaning structure 6 on the cleaning adjustment structure 5, the rotating cleaning structure 6 being rotatably connected to the cleaning adjustment structure 5; and a cleaning liquid spraying structure 7 inside the handle 1 for spraying cleaning liquid, the spraying end of the cleaning liquid spraying structure 7 being located at the outer tube 2.

[0043] It should be noted that this external auditory canal cleaner should be used under strong light to better clean the earwax in the external auditory canal, resulting in a more thorough and effective cleaning.

[0044] Specifically, the sealing and moving structure 4 includes a hollow tube 41, a rotating hand disc 42, a rotating gear 43, a rotating shaft 44, and a corrugated air tube 45. The two ends of the hollow tube 41 are respectively connected to the ends of the handle 1 and the outer tube 2. The hollow tube 41 is slidably fitted with the handle 1 and the outer tube 2. The handle 1 is provided with a notch 11. The rotating shaft 44 is rotatably connected inside the handle 1, and the rotating hand disc 42 is connected to the rotating shaft 44. The rotating hand disc 42 is located at the notch 11. The rotating gear 43 is connected to the rotating shaft 44. The hollow tube 41 is provided with a toothed plate 46 at the handle 1. The rotating gear 43 and the toothed plate 46 mesh with each other. The corrugated air tube 45 is connected inside the hollow tube 41. One end of the corrugated air tube 45 is connected to an air pump 48, and the other end of the corrugated air tube 45 is connected to the sealing airbag 3.

[0045] It should be noted that the air pump 48 has an air valve. When the air pump 48 is working, it can inflate the occlusive airbag 3. After the external auditory canal is cleaned, the air valve on the air pump 48 is opened to expel the gas from the inflated occlusive airbag 3.

[0046] In this embodiment, when cleaning the external auditory canal, it is necessary to seal the external auditory canal and the middle auditory canal to prevent the cleaning solution from flowing into the middle auditory canal.

[0047] When the middle ear canal is blocked, the rotating hand disc 42 is rotated, which drives the rotating shaft 44 to rotate, causing the rotating gear 43 to rotate on the toothed plate 46 on the hollow tube 41. This causes the hollow tube 41 to move outward within the handle 1 and the outer tube 2, moving the blocking airbag 3 towards the middle ear canal. When it reaches the junction of the middle ear canal and the external ear canal, the movement stops. Then, the air pump 48 works to deliver gas through the corrugated air tube 45 to the blocking airbag 3, causing the blocking airbag 3 to expand and fit against the external ear canal, blocking the deepest part of the external ear canal and preventing the cleaning solution from flowing into the middle ear canal and causing contamination of the middle ear canal.

[0048] Since the length of the external auditory canal varies depending on the user, the position of the occlusive airbag 3 needs to be adjusted during cleaning. The position of the occlusive airbag 3 is moved by the movement of the hollow tube 41 to block the entrance of the middle ear canal and prevent the cleaning solution from flowing in and causing inflammation of the middle ear canal. In addition, depending on the needs of use, for some users who only need to clean a certain part of the external auditory canal without cleaning the entire external auditory canal, the position of the occlusive airbag 3 in the external auditory canal can be adjusted at any time. According to the position of the cerumen, the occlusive airbag 3 is positioned inside the cerumen, exposing the cerumen to the outside so that it can be soaked by the cleaning solution.

[0049] It should be noted that the sealing airbag 3 is in a drooping state before use and can move with the movement of the hollow tube 41.

[0050] Specifically, the rotating hand disc 42 is provided with an abutting screw 47, which is threadedly connected to the rotating hand disc 42. After the rotating hand disc 42 is rotated, the position of the blocking airbag 3 is moved to the connection between the external auditory canal and the middle auditory canal. Then, the abutting screw 47 is rotated so that it abuts against the notch 11, preventing the rotating hand disc 42 from rotating and causing the position of the blocking airbag 3 to shift, which could lead to leakage of cleaning fluid in the external auditory canal and cause inflammation of the ear canal.

[0051] Specifically, the cleaning adjustment structure 5 includes an adjustment motor 51, an adjustment screw 52, ​​an adjustment cylinder 53, and an adjustment plate 54. The two ends of the adjustment screw 52 are rotatably connected inside the outer tube 2 and the adjustment screw 52 extends into the handle 1. The adjustment motor 51 is located inside the handle 1 and is connected to the adjustment screw 52 in a transmission manner. The adjustment plate 54 is threadedly connected to the adjustment screw 52 and is slidably engaged with the slide groove 21. The adjustment cylinder 53 is slidably connected to the outside of the outer tube 2 and is connected to the adjustment plate 54.

[0052] The rotating cleaning structure 6 includes a rotating motor 61, a rotating cover 62, a rotating gear ring 63, rotating shafts 64, a mounting cylinder 65, and an arc-shaped plate 66. The rotating motor 61 is located inside the adjusting cylinder 53, and a rotating gear 67 is provided on the main shaft of the rotating motor 61. The rotating cover 62 is rotatably connected to the top of the adjusting cylinder 53, and the rotating gear 67 is located inside the rotating cover 62 and meshes with the rotating gear ring 63. There are six rotating shafts 64, which are horizontally rotatably connected to the rotating cover at equal intervals. On the side wall of 62, a cleaning brush 68 is provided at the end of the rotating shaft 64. The arc plate 66 is located at the other end of the rotating shaft 64 and slides at the bottom of the mounting cylinder 65. Two pulleys 69 are provided on the arc plate 66. The mounting cylinder 65 is connected to the outer wall of the adjusting cylinder 53. The mounting cylinder 65 is provided with a sliding opening. A triangular guide block 651 connected to the mounting cylinder 65 is provided at the sliding opening. A sliding channel 652 for the two pulleys 69 to slide is formed between the triangular guide block 651 and the sliding opening.

[0053] In this embodiment, after the cleaning solution is sprayed into the external auditory canal and soaked for a period of time, the rotary motor 61 drives the rotary gear 67 to rotate on the rotary gear ring 63, thereby causing the rotary cover 62 to rotate on the adjusting cylinder 53. The rotation of the rotary cover 62 causes six rotary shafts 64 to rotate around the axis of the rotary cover 62, thereby causing the cleaning brushes 68 on the rotary shafts 64 to rotate, thus cleaning the earwax in the external auditory canal.

[0054] During the rotation of the rotating shaft 64, the arc-shaped plate 66 on the other end of the rotating shaft 64 will rotate on the mounting cylinder 65. When the two pulleys 69 on the arc-shaped plate 66 rotate to the sliding opening on the mounting cylinder 65, the position of the arc-shaped plate 66 will rotate. The arc-shaped plate 66 will rotate from a horizontal state to a vertical state, causing the two pulleys 69 to rotate within the sliding channel 652. This will cause the arc-shaped plate 66 to rotate around the axis of the rotating shaft 64, cleaning and scraping the earwax in the external auditory canal.

[0055] During use, the cleaning brush 68 can rotate both along the axis of the rotating cover 62 and along the axis of the rotating shaft 64, thereby better cleaning and scraping away the earwax in the external auditory canal.

[0056] During the cleaning process, the adjusting motor 51 drives the adjusting screw 52 to rotate on the outer tube 2 and the handle 1. The rotation of the adjusting screw 52 causes the adjusting plate 54 to move horizontally within the slide groove 21. The movement of the adjusting plate 54 causes the adjusting cylinder 53 to move up and down on the outer tube 2, thereby causing the positions of several cleaning brushes 68 to move along the length of the outer tube 2, performing a comprehensive cleaning of earwax in different parts of the external auditory canal, resulting in a cleaner external auditory canal.

[0057] During the cleaning process, the position of the adjusting cylinder 53 on the outer tube 2 can be adjusted according to the different lengths of the user's external auditory canal, thereby adjusting the position of several cleaning brushes 68 to clean the earwax in different locations of the external auditory canal.

[0058] It should be noted that during the adjustment of the cleaning brush 68, the use of a screw for adjustment allows for more precise position adjustment during the movement of the cleaning brush 68.

[0059] Specifically, the cleaning brush 68 is made of a flexible, elastic linear material; during the cleaning process of the earwax in the external auditory canal, the flexible, elastic cleaning brush 68 can scrape off the stuck earwax without causing damage to the external auditory canal.

[0060] Specifically, the cleaning fluid spraying structure 7 includes a cleaning fluid storage tank 71, an extraction pump 72, a delivery pipe 73, and an annular pipe 74. The cleaning fluid storage tank 71 is located inside the handle 1. The cleaning fluid storage tank 71 is provided with an inlet that connects to the outside of the handle 1. A plug 76 is provided at the inlet. The extraction pump 72 is connected to the cleaning fluid storage tank 71. The annular pipe 74 is connected to the outer wall of the outer pipe 2 and is located at the connection between the outer pipe 2 and the handle 1. The delivery pipe 73 is connected to the extraction pump 72 and the annular pipe 74. The annular pipe 74 is provided with several spray nozzles.

[0061] During cleaning, the plug 76 is opened to allow the cleaning solution to be poured into the cleaning solution storage tank 71 through the inlet. Then, the pump 72 operates to transport the cleaning solution through the delivery pipe 73 to the annular pipe 74. After that, the cleaning solution is sprayed into the external auditory canal through several spray nozzles to fill the entire external auditory canal and soak the earwax in the external auditory canal for about 10-15 minutes. Afterward, the earwax can be cleaned by rotating the cleaning brush 68.

[0062] Specifically, the cleaning solution storage tank 71 is equipped with a heating element 75; before the cleaning solution is delivered to the external auditory canal, the cleaning solution in the cleaning solution storage tank 71 is heated by the heating element 75 to a temperature suitable for the human body, approximately 37 degrees Celsius, so that the cleaning solution will not feel cold when cleaning the external auditory canal, thus preventing discomfort to the user.

[0063] Specifically, a transparent and visual rubber cover 8 is provided at the connection between the handle 1 and the outer tube 2. The transparent and visual rubber cover 8 is provided with a threaded ring. The transparent and visual rubber cover 8 is threadedly connected to the handle 1 through the threaded ring. The handle 1 is provided with a threaded section that is threadedly connected to the threaded ring.

[0064] Before cleaning, the transparent and visible rubber cover 8 can be rotated and installed on the threaded end of the outer tube 2 through the threaded ring to prevent the cleaning fluid from overflowing onto the user or medical staff during the cleaning of the earwax in the external auditory canal by several cleaning brushes 68. The transparent and visible rubber cover 8 can cover the cleaning fluid to prevent splashing.

[0065] During use, the transparent rubber cover 8 adheres to the user's earlobe, keeping the handle 1 in a vertical position. When the transparent rubber cover 8 adheres to the earlobe during cleaning, the position of the entire cleaner will not shake or vibrate. Once the position of the transparent rubber cover 8 is determined, the positions of the blocking airbag 3 and the cleaning brush 68 can be adjusted to clean various parts of the external auditory canal.

[0066] Specifically, the handle 1 is equipped with a rechargeable lithium battery; the lithium battery is electrically connected to the heating element 75, the extraction pump 72, the rotary motor 61 and the adjusting motor 51 for power supply, and the lithium battery can be recharged after use.

[0067] The cleaning process can be divided into the following steps:

[0068] The first step is to place the external auditory canal cleaner in the user's external auditory canal and fix its position to the user's auricle using the transparent and visible rubber cover 8.

[0069] The second step involves adjusting the position of the blocking airbag 3 to the innermost layer of the external auditory canal by using the blocking moving structure 4, and then inflating it.

[0070] The third step involves spraying cleaning solution into the external auditory canal through the cleaning solution spraying structure 7 to soak the earwax inside the external auditory canal.

[0071] The fourth step is to use the rotating cleaning structure 6 to drive several cleaning brushes 68 to clean and scrape away the earwax that is attached and stuck in the external auditory canal after the soaking is completed.

[0072] Fifth step: During the cleaning process, the cleaning brush 68 can be moved along the length of the external auditory canal by the operation of the cleaning adjustment structure 5 to thoroughly clean the earwax in the external auditory canal.

[0073] Step 6: Rotate and remove the transparent, visible rubber cover 8 from the handle 1. Then, use the existing suction pipe and pump to extract the cleaning solution and drain it outwards. Dry the water inside the external auditory canal using existing tools.

[0074] Step 7: After cleaning and drying, expel the air from the sealing airbag 3 and remove the entire external auditory canal cleaner from the external auditory canal to complete the cleaning of the external auditory canal.

[0075] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
