Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a reshaping earmuff structure. Background Technology

[0002] Orthopedic earmuffs are protective and fixation devices used after ear plastic surgery (such as ear correction and ear reconstruction). They are mostly made of medical-grade materials and filled with soft sponge or memory foam to ensure that they fit the patient's ear while effectively reducing direct contact with external pressure on the ear, preventing postoperative collisions and compression, helping with postoperative shaping and recovery, and avoiding secondary damage to the surgical site.

[0003] In existing technologies, traditional orthopedic earmuffs only have a protective function and need to be filled with medical cotton or other shaping materials to shape the patient's ear. They often cannot fit the shape of the ear after orthopedic surgery, which can easily lead to uneven pressure or displacement, affecting the recovery effect and recovery process after ear orthopedic surgery. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a reshaping earmuff structure that solves the problem that traditional reshaping earmuffs only have a protective function and require filling them with medical cotton or other shaping materials to shape the patient's ear. This often results in an inability to fit the shape of the ear after reshaping, which can easily lead to uneven pressure or displacement, affecting the recovery effect and process after ear reshaping surgery.

[0015] Beneficial effects

[0016] This invention provides a reconstructive earmuff structure. It offers the following advantages: Through the cooperation of a ring-shaped protective tube, a cover plate, an inner support structure, and a wearing fixation structure, this reconstructive earmuff structure protects the patient's ear during wear. Two airbags provide support from the front and back of the ear, ensuring a close fit to the reconstructed ear. This provides uniform support, aiding in the fixation and restoration of the ear's shape. It effectively prevents uneven pressure or displacement, enabling the reconstructive earmuff to not only protect the patient's ear but also provide excellent support and stability, thus improving postoperative recovery after ear reconstruction.

[0017] The orthopedic earmuffs utilize a three-point fixation design, achieved through the coordination of a top-mounted fixation strap, a back-mounted fixation strap, a chin fixation strap, a connecting structure, and a pressure-reducing structure. When worn, the top-mounted and back-mounted straps secure the earmuffs to the top and back of the patient's head, while the chin fixation strap wraps around the patient's chin. All three straps are made of elastic materials to adapt to different head shapes. The pressure-reducing structure effectively disperses pressure on the patient's head, ensuring a perfect fit and improving the stability of the earmuffs. This reduces discomfort and allows for extended wear. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In existing technologies, traditional orthopedic earmuffs only have a protective function and need to be filled with medical cotton or other shaping materials to shape the patient's ear. They often cannot fit the shape of the ear after orthopedic surgery, which can easily lead to uneven pressure or displacement, affecting the recovery effect and recovery process after ear orthopedic surgery.

[0028] In view of this, the present invention provides a reconstructive earmuff structure. Through the cooperation of the annular protective tube, the cover plate, the inner support structure, and the wearing and fixing structure, when the reconstructive earmuff is worn, the annular protective tube and the cover plate cover the patient's ear, protecting the patient's ear and effectively avoiding pain and secondary injury caused by accidental bumps to the ear after surgery. By inflating two air bladders, the earmuff provides support from the front and back, closely fitting the reconstructed ear and providing uniform support. This helps to fix and restore the shape of the ear and effectively prevents uneven pressure or displacement. Thus, the reconstructive earmuff not only has the function of protecting the patient's ear but also has good support and stability, thereby improving the recovery effect after ear reconstructive surgery.

[0029] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0030] Depend on Figure 1-7 It is known that a reshaping earmuff structure includes an annular protective tube 1, with a cover plate 2 connected to the outer wall of the annular protective tube 1 on the side that is far apart from each other. The reshaping earmuff structure also includes an inner support structure 3 and a wearing fixation structure 4. The inner support structure 3 is disposed inside the annular protective tube 1; the wearing fixation structure 4 is disposed above and below the annular protective tube 1. The inner support structure 3 can support and position the patient's ear inside the annular protective tube 1, and the wearing fixation structure 4 makes the annular protective tube 1 stably worn on the patient's ear.

[0031] In the specific implementation process, it is worth noting that through the cooperation between the annular protective tube 1 and the cover plate 2, both made of medical-grade materials, the annular protective tube 1 and the cover plate 2 cover the patient's ear during the wearing of the orthopedic earmuff, protecting the ear and preventing postoperative impact. Furthermore, the annular protective tube 1 and the cover plate 2 are detachable, allowing medical staff to easily check, apply medication, or adjust the patient's ear by opening the cover plate 2, increasing the practicality of the orthopedic earmuff and the convenience of postoperative care. The internal support structure 3 inflates the two air bladders 31, providing support at the front and back of the patient's ear and closely fitting the reconstructed ear, ensuring even pressure and effectively preventing uneven pressure or displacement, thus improving the recovery effect after ear reconstruction surgery. The wearing fixation structure 4 adopts a three-point fixation design, ensuring even pressure distribution during the wearing of the orthopedic earmuff. During the procedure, multiple fixing straps are used to secure the earmuff to the top, back, and chin of the patient's head, ensuring a stable fit and improving the stability of the earmuff. Through the cooperation of the annular protective tube 1, cover plate 2, inner support structure 3, and wearing fixation structure 4, the annular protective tube 1 and cover plate 2 cover the patient's ear during wear, protecting it and effectively preventing pain and secondary injury caused by accidental ear bumps after surgery. Inflating the two air bladders 31 provides support from the front and back of the ear, ensuring a close fit and providing even support. This helps fix and restore the ear shape, effectively preventing uneven pressure or displacement. Therefore, the earmuff not only protects the patient's ear but also provides excellent support and stability, thus improving the recovery effect after ear plastic surgery.

[0032] Understandably, the number of orthopedic earmuffs can be adjusted according to the patient's surgical condition. For example, when a patient is having surgery on one ear, the ring-shaped protective tube 1 and cover plate 2 on the surgical side can be used alone. By adjusting the fixing strap of the wearing fixation structure 4, protection and support can be provided for the unilateral ear, allowing the patient to wear the orthopedic earmuff more comfortably and without feeling any additional pressure or discomfort on the non-surgical side, thus improving the patient's comfort.

[0033] Furthermore, the inner support structure 3 includes an airbag 31, a silicone pad 32, an inflation port 33, a sealing structure 34, and a support sensing component 35. Multiple airbags 31 are provided, each fixedly connected to both sides of the inner wall of the annular protective tube 1. The silicone pad 32 is fitted to the outer wall of the airbag 31 and fixedly connected to the inner wall of the annular protective tube 1. The inflation port 33 is located on both sides of the outer wall of the annular protective tube 1 and communicates with the airbag 31. The sealing structure 34 is located inside the inflation port 33. The support sensing component 35 is located on one side of the outer wall of the annular protective tube 1. Through the cooperation of the airbag 31 and the inflation port 33, gas is inflated into the airbag 31, allowing the airbag 31 and silicone pad 32 to support and position the patient's ear. The sealing structure 34 seals the airbag 31, and the support sensing component 35 senses the support status of the airbag 31 and silicone pad 32.

[0034] In the specific implementation process, it is worth noting that the airbag 31 is made of medical-grade elastic material, which has good sealing performance, and is designed according to the shape of the front and back of the ear to ensure even distribution of support force. The silicone pad 32 is made of medical-grade soft material, which has good comfort and fit, and can closely fit the patient's ear, effectively preventing the airbag 31 from directly contacting the patient's ear and causing pressure. Through the cooperation between the annular protective tube 1, the airbag 31, the silicone pad 32, the inflation port 33, the sealing structure 34, and the support sensing component 35, the airbag 31... Using the ear contour as a model, an appropriate amount of gas is inflated into the airbag 31 through the inflation port 33, which inflates the silicone pad 32 and fits it tightly against the reshaped ear, ensuring that the ear receives uniform pressure and effectively preventing uneven pressure or displacement. After inflation, the airbag 31 is sealed by the sealing structure 34. The support sensing component 35 senses the support status of the airbag 31 and silicone pad 32, allowing medical staff to understand the support status of the reshaped earmuff on the patient's ear in real time and make adjustments as needed to ensure the best support effect.

[0035] Furthermore, the sealing structure 34 includes a sealing plug 341, a limiting plate 342, a connecting rod 343, a fixing plate 344, an air vent 345, a compression spring 346, and a sealing cover 347. The sealing plug 341 is movably connected to the inside of the inflation port 33; the limiting plate 342 is disposed on the side of the sealing plug 341 near the airbag 31; the connecting rod 343 is fixedly connected to the side of the sealing plug 341 near the airbag 31; the fixing plate 344 is fixedly connected to the inner wall of the inflation port 33 near the end of the airbag 31, and the inner wall is fitted to the connecting rod 343; the air vent 345 is provided with multiple... The limiting plate 342 and the fixing plate 344 are equidistantly distributed on the outside of the connecting rod 343; the compression spring 346 is set on the outside of the connecting rod 343 and abuts against the limiting plate 342 and the fixing plate 344; the sealing cover 347 is connected to the inflation port 33; wherein, when the airbag 31 is inflated, the sealing plug 341 moves inward, allowing gas to enter the interior of the airbag 31 through the air guide hole 345. After the airbag 31 is inflated, the sealing plug 341 seals the airbag 31 under the action of the compression spring 346, and the sealing cover 347 closes the inflation port 33.

[0036] In the specific implementation process, it is worth noting that, through the cooperation between the airbag 31, inflation port 33, sealing plug 341, limiting plate 342, connecting rod 343, fixing plate 344, air guide hole 345, compression spring 346, and sealing cover 347, when the airbag 31 is inflated, the sealing plug 341 moves towards the fixing plate 344 under the action of air pressure, compressing the compression spring 346, releasing the seal on the inflation port 33, and allowing gas to pass through the air guide hole 345. 5. Enter the interior of the airbag 31 to inflate the airbag 31. When the airbag 31 is inflated, the compression spring 346 gives the limiting plate 342 an elastic force away from the fixed plate 344, so that the sealing plug 341 is pressed against the inflation port 33 again, thereby sealing the inflation port 33 and preventing gas from leaking from the inside of the inflation port 33. The sealing cover 347 further seals the inflation port 33, thereby improving the sealing effect of the airbag 31 and making the airbag 31 provide stable support for the patient's ear.

[0037] Furthermore, the support sensing component 35 includes a thin-film pressure sensor 351, a controller 352, and an indicator light 353. The thin-film pressure sensor 351 is installed on the side where the airbag 31 and the silicone pad 32 are close to each other. The controller 352 is disposed on one side of the outer wall of the annular protective tube 1 and is electrically connected to the thin-film pressure sensor 351. The indicator light 353 is disposed on both sides of the outer wall of the controller 352. In this way, the support status of the silicone pad 32 and the patient's ear is sensed by the cooperation of the thin-film pressure sensor 351 and the controller 352, and the support status is indicated by the indicator light 353.

[0038] In the specific implementation process, it is worth noting that when the airbag 31 is inflated, the silicone pad 32 fits and supports the patient's ear. The thin-film pressure sensor 351 senses the contact pressure between the silicone pad 32 and the patient's ear in real time and transmits the sensed data to the controller 352. The controller 352 processes and analyzes the received pressure data according to a preset support state threshold to determine whether the support state is appropriate. When the pressure value reaches the preset appropriate range, the indicator light 353 lights up green, indicating that the support state is good; if the pressure value is lower than the preset range, the indicator light 353 lights up red, indicating that adjustment is needed to ensure that the ear is adequately supported and protected. The specific models of the thin-film pressure sensor 351, controller 352, and indicator light 353 are not limited, as long as they meet the usage requirements.

[0039] Furthermore, the wearing fixation structure 4 includes a top fixation strap 41, a back fixation strap 42, a chin fixation strap 43, a fixation strap connecting structure 44, and a pressure relief structure 45. The top fixation strap 41 is located at the top of the annular protective tube 1; the back fixation strap 42 is fixedly connected to one side of the top fixation strap 41; the chin fixation strap 43 is located at the bottom of the annular protective tube 1; the fixation strap connecting structure 44 is located at both ends of the top fixation strap 41 and the chin fixation strap 43; the pressure relief structure 45 is connected to the top fixation strap 41, the back fixation strap 42, and the chin fixation strap 43. The top fixation strap 41 and the chin fixation strap 43 are connected to the annular protective tube 1 through the fixation strap connecting structure 44. The top fixation strap 41, the back fixation strap 42, and the chin fixation strap 43 ensure that the annular protective tube 1 is stably worn on both sides of the patient's head, and the pressure relief structure 45 reduces the pressure on the patient's head.

[0040] In the specific implementation process, it is worth noting that the wearing fixation structure 4 adopts a three-point fixation design. When the orthopedic earmuff is worn, the top fixation strap 41 and the back fixation strap 42 are fixed on the top and back of the patient's head, while the chin fixation strap 43 wraps around the patient's chin, ensuring that the orthopedic earmuff fits firmly against the patient's ear and improving the stability of wearing the orthopedic earmuff. At the same time, the top fixation strap 41, the back fixation strap 42, and the chin fixation strap 43 are all made of materials with a certain degree of elasticity and are fixed to the annular protective tube 1 through the fixation strap connecting structure 44. This can adapt to different head shapes of patients, ensuring that the orthopedic earmuff fits perfectly against the patient's head and reducing discomfort when wearing it. The setting of the pressure relief structure 45 further improves the comfort of wearing it, effectively dispersing the pressure of the top fixation strap 41, the back fixation strap 42, and the chin fixation strap 43 on the patient's head and avoiding the pressure caused by wearing it for a long time.

[0041] Understandably, when a patient undergoes surgery on one ear, the fixation strap of the fixation structure 4 is adjusted accordingly. The head fixation strap 41 and the chin fixation strap 43 are connected or integrally formed at the end of the orthopedic earmuff away from the surgical side and are worn in the same way to achieve unilateral wearing of the orthopedic earmuff, so that the patient can wear the orthopedic earmuff more comfortably and avoid feeling additional pressure or discomfort on the non-surgical side.

[0042] Furthermore, the fixing strap connection structure 44 includes a fixing clip 441 and an insertion port 442. The fixing clip 441 is fixedly connected to both ends of the head fixing strap 41 and the chin fixing strap 43. The insertion port 442 is located on the upper and lower outer walls of the annular protective tube 1, and its inner wall is fitted to the fixing clip 441. The head fixing strap 41 and the chin fixing strap 43 are fixed to the annular protective tube 1 through the cooperation of the fixing clip 441 and the insertion port 442.

[0043] In the specific implementation process, it is worth noting that by inserting the fixing clips 441 of the top fixing strap 41 and the chin fixing strap 43 into the insertion ports 442 located above and below the annular protective tube 1, the top fixing strap 41 and the chin fixing strap 43 are securely connected to the annular protective tube 1, ensuring that they are not easy to fall off when worn by the patient. Furthermore, by separating the fixing clips 441 from the insertion ports 442, the fixing straps can be separated from the annular protective tube 1, improving the convenience of wearing and removing the orthopedic earmuff.

[0044] Furthermore, the decompression structure 45 includes a decompression pad 451 and a chin rest 452. The decompression pad 451 is connected to the outer wall of the top fixation strap 41 and the back fixation strap 42. The chin rest 452 is connected to the outer wall of the chin fixation strap 43. Through the cooperation of the decompression pad 451 and the chin rest 452, the pressure on the patient's head caused by the top fixation strap 41, the back fixation strap 42 and the chin fixation strap 43 is reduced, and the stability of the annular protective tube 1 when worn is improved.

[0045] In the specific implementation process, it is worth noting that the pressure relief pads 451 set on the top fixation strap 41 and the back fixation strap 42 can be adaptively adjusted according to the patient's head contour, effectively dispersing the pressure of the top fixation strap 41 and the back fixation strap 42 on the patient's head, ensuring comfort and stability when wearing, reducing the pressure on the patient's head, and avoiding discomfort caused by wearing for a long time. The chin support 452 fits closely to the patient's chin, further improving the stability and comfort of wearing the orthopedic earmuff.

[0046] Furthermore, a limiting structure 5 is provided on the side of the annular protective tube 1 and the cover plate 2 that are close to each other. The limiting structure 5 includes a limiting protrusion 51 and a limiting groove 52. The limiting protrusion 51 is provided on the inner wall of the cover plate 2; the limiting groove 52 is provided on the outer wall of the annular protective tube 1, and the inner wall is connected to the limiting protrusion 51. The connection stability between the annular protective tube 1 and the cover plate 2 is improved by the cooperation of the limiting protrusion 51 and the limiting groove 52.

[0047] In the specific implementation process, it is worth noting that when the cover plate 2 is fastened into the annular protective tube 1, the limiting protrusion 51 is inserted into the inside of the limiting groove 52, which improves the connection stability between the annular protective tube 1 and the cover plate 2, avoids the situation of falling off during use, and improves the stability and safety of the shaping earmuff structure.

[0048] Furthermore, the outer wall of the cover plate 2 is provided with a ventilating structure 6, which includes a first ventilating hole 61 and a second ventilating hole 62. Multiple first ventilating holes 61 are provided and are equidistantly opened on the outer wall of the silicone pad 32; multiple second ventilating holes 62 are provided and are equidistantly opened on the outer wall of the cover plate 2. The cooperation of the first ventilating holes 61 and the second ventilating holes 62 improves the air permeability inside the annular protective tube 1.

[0049] In the specific implementation process, it is worth noting that by setting the first vent 61 in the silicone pad 32 and the second vent 62 in the cover plate 2, the breathability of the orthopedic earmuff is improved, avoiding local overheating or stuffiness of the patient's ear and reducing the patient's discomfort during use.

[0050] Furthermore, an inner lining pad 7 is provided on the side of the annular protective tube 1 that is close to each other. The inner lining pad 7 is used to improve the comfort of wearing the orthopedic earmuff.

[0051] In the specific implementation process, it is worth noting that the inner lining pad 7 is used to improve the comfort of wearing the orthopedic earmuff. The inner lining pad 7 is made of soft and breathable material, which can conform to the contour of the patient's head, reduce the friction and pressure of the annular protective tube 1 on the patient's head, and further improve the wearing experience of the orthopedic earmuff structure.

[0052] Working principle: After the patient completes ear plastic surgery, the annular protective tube 1 is inserted into the outer side of the patient's ear, ensuring the inner lining pad 7 fits tightly against the ear. Medical tape is used to initially fix the annular protective tube 1. A syringe is inserted into the inflation port 33 to inflate the airbag 31. Simultaneously, the support height of the silicone pad 32 is observed. After the silicone pad 32 forms a supportive fit on both sides of the patient's ear, the thin-film pressure sensor 351 senses the contact pressure between the silicone pad 32 and the patient's ear in real time and transmits the sensed data to the controller 352. Upon receiving the data, the controller 352 determines whether the support is appropriate. If the pressure value reaches the preset appropriate range, the indicator light 353 illuminates green, indicating good support. Medical staff can then stop inflating the airbag 31. The sealing plug 341 of the sealing structure 34 automatically seals the airbag 31, and the sealing cap 347 is inserted into the inflation port 33, providing support and positioning for the patient's ear. The head fixation strap 41 and the back of the head fixation strap are then... The earmuff 42 is wrapped around the top and back of the patient's head, and the fixing clip 441 is inserted into the insertion port 442 at the top of the annular protective tube 1. The chin fixing strap 43 is wrapped around the patient's chin, and the fixing clip 441 is inserted into the insertion port 442 at the bottom of the annular protective tube 1 to ensure that the orthopedic earmuff is stably fixed on the patient's head. The cover plate 2 is fastened into the outside of the annular protective tube 1, and the medical tape used for auxiliary fixation is removed, so that the orthopedic earmuff forms a covering protection and stable fit support for the patient's ear. When it is necessary to check the recovery of the patient's ear, the cover plate 2 can be removed from the annular protective tube 1 to directly observe the patient's ear. When it is necessary to remove the orthopedic earmuff, a thin rod is inserted into the inflation port 33 to push the sealing plug 341, so that the gas inside the air bag 31 is discharged under pressure. After losing support, the silicone pad 32 resets and separates from the patient's ear, so that the orthopedic earmuff can be removed from the patient's head, completing the removal process of the orthopedic earmuff.
