Description

Technical Field

[0001] The invention belongs to the technical field of post-operative ear care equipment, and in particular relates to an ear keloid post-operative fixator. Background Art

[0002] Ear scars, especially those on the earlobes, are mainly caused by excessive growth of abnormal scar tissue after healing of skin injuries caused by ear piercing, external trauma, infection, or unknown reasons. They have serious effects on the patient's facial appearance and mental health. Currently, the best treatment for ear scars is a comprehensive treatment method of surgical resection followed by auxiliary radiotherapy. Correct bandaging and fixation after surgery not only has the effects of compression to stop bleeding, protect wounds, prevent infection and reduce pain, but also appropriate pressure bandage on the wound can also prevent and treat keloids at an early stage. Therefore, postoperative bandaging and fixation are very important.

[0003] At present, multiple tapes are often used to wrap around the ear for clinical fixation. Due to the special anatomical structure of the ear, the simple use of tape to bandage is not firm, and the gauze is loose, which cannot play the role of bandaging and fixing the ear wound. If the wound surface is exposed, it may even cause infection, affecting wound healing and postoperative effects. At the same time, most traditional fixators use earmuff-type covers to cover the ear inside, so as to protect the ear and fix the gauze. However, since the ear is after surgery, in order to relieve postoperative pain, most of them will apply ice to the ear to achieve a soothing effect and reduce postoperative discomfort. When applying ice, the cover needs to be removed for operation, which is inconvenient to use. At the same time, frequent wearing of the cover is also prone to accidental injury to the affected area, which is not conducive to the healing of the affected area. Summary of the invention

The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned figures are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The embodiment of the present invention provides a fixator for postoperative keloid excision of the ear, such as Figure 1-13 As shown, the postoperative fixator for ear keloid excision comprises: an elastic band component 1 and a shell 2 arranged on the elastic band component 1 for fixing gauze and protecting the patient's ears; a water tank 3 installed in the shell 2 for supplying cold water; a water bag 4 installed on one side of the water tank 3 for applying ice to the patient's ears; a water tank 5 arranged on one side of the shell 2, and a cooling plate 6 for cooling water installed in the water tank 5; a water pump 30 installed on the water tank 5 for supplying water to the water bag 4 and the water tank 3; a group of hoses 29 detachably installed on the drainage end of the water pump 30 and the shell 2; and a heat dissipation mechanism arranged on the water tank 5 for dissipating heat from the cooling plate 6.

[0036] In this embodiment, first, gauze is wrapped around the affected part of the ear, and then the housing 2 of the fixator is placed on the patient's ear, and the ear is tightly wrapped by the internal water bag 4, so as to achieve stable bandaging and fixation. A water tank 3 and a water bag 4 are provided inside the fixator, which are connected to a water tank 5 through a hose 29. A cooling sheet 6 is installed in the water tank 5 to cool the water therein. A water pump 30 draws water from the water tank 5 and sends the water into the water tank 3 and the water bag 4 through the hose 29 to apply ice to the ear. The water is continuously cooled by the cooling sheet 6 during the circulation process, thereby continuously providing a cold compress effect for the ear.

[0037] Ice compress by water bag 4 can effectively reduce postoperative ear swelling and pain, accelerate wound healing and improve healing efficiency. At the same time, the design of shell 2 and water bag 4 makes the bandage more stable, avoids the problems of loose gauze and exposed wound surface, thereby reducing the risk of infection and facilitating postoperative recovery. The design of elastic band assembly 1 and shell 2 enables the fixator to fit closely to the patient's ear while providing sufficient comfort. In addition, proper pressure bandage and ice compress can not only reduce pain and swelling, but also prevent and treat the formation of keloids at an early stage, which helps to improve the patient's facial appearance and mental health.

[0038] In a further preferred embodiment of the present invention, the elastic band assembly 1 is composed of a support frame 8, an elastic band for the back of the head, an elastic band for the top of the head, an elastic band for the chin, elastic bands at four corners 10, a group of connecting plates 7, and a group of first bayonet 9. The support frame 8 is arranged above the shell 2 and is rotatably connected to the shell 2. A group of connecting plates 7 are respectively installed on the shell 2 and the support frame 8. The elastic band for the back of the head, the elastic band for the top of the head and the elastic band for the chin are all installed on a group of connecting plates 7 through buckles 9. The four-corner elastic bands 10 are arranged on one side of the shell 2, and the four-corner elastic bands 10 are placed on the patient's forehead.

[0039] In this embodiment, the elastic band assembly 1 is fixed to the patient's head by means of a buckle 9, which can ensure that the shell 2 will not be displaced during the patient's activities, thereby maintaining the bandaging and fixation effects. The support frame 8 is rotatably connected to the shell 2, so that when changing the gauze, the shell 2 can be easily opened and the gauze can be replaced.

[0040] In a further preferred embodiment of the present invention, a connecting box 11 is provided on one side of the four-corner elastic band 10, and a partition 12 is fixedly installed in the connecting box 11, and the partition 12 separates the connecting box 11 to form an installation cavity and a connecting cavity, and a connecting block 15 is provided on one side of the four-corner elastic band 10, and the connecting block 15 is inserted into the connecting box 11, and a bidirectional screw 13 is rotatably installed in the installation cavity, and a group of limit rods 14 are threadedly sleeved on the bidirectional screw 13, and a group of limit rods 14 are inserted into the connecting block 15.

[0041] In this embodiment, during the assembly of the four-corner elastic band 10, it is first necessary to accurately insert the connecting block 15 into the connecting box 11. Subsequently, by rotating the bidirectional screw 13, a set of limit rods 14 can be driven to slide relative to each other until they are tightly inserted into the connecting block 15. This process is not only simple and quick, but also ensures a firm connection between the four-corner elastic band 10 and the connecting box 11 through the tight fit of the limit rods 14. The sliding and fixation of the limit rods 14 can be achieved by rotating the bidirectional screw 13, which greatly simplifies the assembly process and improves work efficiency. The limit rods 14 are tightly inserted into the connecting block 15, which effectively prevents the four-corner elastic band 10 from loosening or falling off during use, thereby ensuring the stability and safety of the equipment.

[0042] In a further preferred embodiment of the present invention, a connecting piece 16 is fixedly installed on one side of the connecting block 15, a connecting belt 35 is installed on the elastic belt on the top of the head, and buckles 17 are installed on the connecting piece 16, the connecting belt 35 and the four-corner elastic belts 10, and a group of buckles 17 are connected to each other.

[0043] In this embodiment, when assembling the four-corner elastic band 10, it is only necessary to snap-connect the buckle 2 17 on the connecting piece 16 with the connecting band 35 or the buckle 2 17 on the four-corner elastic band 10, thereby facilitating the replacement of the four-corner elastic band with the frame 41 and the replacement of the four-corner elastic band without the frame 41. The mutual snap connection of the buckle 2 17 ensures a firm connection between the four-corner elastic band 10 and the elastic band on the top of the head, effectively preventing loosening or falling off that may occur during use. At the same time, the design of the buckle 2 17 makes the assembly process simpler and faster, and the assembly can be completed without using additional tools or complicated operating steps.

[0044] In a further preferred embodiment of the present invention, a fixing mechanism for fixing the shell 2 is provided on the connection box 11 and the shell 2, and the fixing mechanism includes: a fixing block 18 fixedly installed on one side of the shell 2, and the fixing block 18 is rotatably inserted into the connection box 11; a threaded rod 19 rotatably installed on the partition 12; a threaded barrel 20 threadedly sleeved on the threaded rod 19 for limiting the fixing block 18, and the threaded barrel 20 is slidably connected to the slot of the fixing block 18; a driving mechanism provided on the connection box 11 for simultaneously driving the bidirectional screw 13 and the screw 19 to rotate synchronously.

[0045] In this embodiment, when the gauze needs to be replaced, the user only needs to drive the threaded rod 19 to rotate through the driving mechanism. As the threaded rod 19 rotates, the threaded tube 20 will slide along the threaded rod 19 to the outside of the slot of the fixed block 18 until it is completely out of the slot. At this time, the shell 2 can be opened, and the user can conveniently rotate the shell 2 along one side of the support frame 8 to fully open it, so as to replace the gauze. Through the synchronous drive design of the driving mechanism, the user only needs to perform simple operations to open and close the shell 2, which greatly improves the convenience of operation. Through the threaded connection between the threaded rod 19 and the threaded tube 20 and the slot design of the fixed block 18, the stability of the shell 2 during normal use is ensured, and the occurrence of loosening or falling off is effectively prevented.

[0046] In a further preferred embodiment of the present invention, the driving mechanism includes: a connecting rod 24 rotatably installed on the left side of the partition 2; a sprocket 21 fixedly mounted on the connecting rod 24 and the threaded rod 19 respectively; a chain 22 mounted on a group of the sprockets 21; a handle 25 rotatably installed on one side of the connecting box 11; two groups of bevel gears 26 fixedly mounted on the rotating shaft of the handle 25, the connecting rod 24 and the bidirectional screw 13 respectively, and the two groups of bevel gears 26 are meshed with each other.

[0047] In this embodiment, when the user needs to fix or detach the housing 2 and the four-corner elastic band 10 at the same time, he only needs to rotate the handle 25. The rotation of the handle 25 will drive the bevel gear on its rotating shaft to rotate, and then drive the bevel gear on the connecting rod 24 to rotate synchronously. Since the connecting rod 24 is connected to the threaded rod 19 through the chain 22, the threaded rod 19 will also rotate synchronously. At the same time, the rotation of the connecting rod 24 will also drive the bidirectional screw 13 to rotate through another set of bevel gears 26.

[0048] It is worth mentioning that when the threaded barrel 20 slides away from the fixed block 18 (that is, the shell 2 is in the open state), the position of the threaded barrel 20 is exactly located in the middle of the threaded rod 19. At the same time, due to the rotation of the bidirectional screw 13, the limit rod 14 will slide to the half position along the connecting block 15. This design allows the user to stop turning the handle 25 in time when only needing to open the shell 2 without completely disassembling the four-corner elastic band 10, thereby avoiding the limit rod 14 from completely disengaging from the connecting block 15, maintaining the partial assembly state of the four-corner elastic band 10, and ensuring the synchronous rotation of the threaded rod 19 and the bidirectional screw 13 through the transmission mechanism of the bevel gear 26 and the chain 22, thereby improving the stability and reliability of the entire structure. At the same time, the user only needs to turn the handle 25 to achieve synchronous operation of multiple components, thereby greatly simplifying the operation process.

[0049] In a further preferred embodiment of the present invention, a group of guide rods 27 are fixedly installed in the connecting box 11, and a group of guide blocks 28 are slidably sleeved on the guide rods 27 for respectively guiding the limit rods 14 and the threaded cylinder 20, and a limit wheel 23 for limiting the chain 22 is rotatably installed on the left side of the partition 2.

[0050] In this embodiment, the guide rod 27 not only plays a supporting and positioning role, but also provides a precise guide for the sliding of the limit rod 14 and the threaded cylinder 20. In order to ensure that the limit rod 14 and the threaded cylinder 20 can remain stable during the sliding process, a group of guide blocks 28 are slidably sleeved on the guide rod 27. These guide blocks 28 are respectively connected to the limit rod 14 and the threaded cylinder 20, ensuring their stability and accuracy during the sliding process.

[0051] In addition, the main function of the limiting wheel 23 is to limit the chain 22 to prevent it from deviating or jumping during the transmission process, thereby ensuring the stability and reliability of the transmission of the chain 22. Through the coordinated use of the guide rod 27 and the guide block 28, the stability and accuracy of the limiting rod 14 and the threaded tube 20 during the sliding process are ensured, and structural loosening or failure caused by unstable sliding is avoided. The setting of the limiting wheel 23 effectively prevents the chain 22 from deviating or jumping during the transmission process, thereby ensuring the stability and reliability of the transmission of the chain 22 and extending the service life of the chain 22.

[0052] In a further preferred embodiment of the present invention, the heat dissipation mechanism includes: a connecting frame 31 fixedly mounted on the top of the water tank 5, the connecting frame 31 being fixedly connected to the refrigeration fins 6; a group of cooling fins 32 mounted in the connecting frame 31 and in close contact with the refrigeration fins 6, the cooling fins 32 located at the bottom are inserted into the water for cooling the water, and the cooling fins 32 located at the top are used for heat dissipation; a connecting cover 33 mounted on the connecting frame 31 and covering the cooling fins 32; and a fan blade 34 rotatably mounted on the top of the inner wall of the connecting cover 33 for cooling the refrigeration fins 6 and the cooling fins 32.

[0053] In this embodiment, when the refrigeration fin 6 is working, cold air is generated below it, and the cold air is transferred to the water in the water tank 5 through the heat dissipation fins 32 below, thereby realizing the refrigeration of the water. At the same time, heat is generated above the refrigeration fin 6, and the heat is dissipated into the air through the heat dissipation fins 32 above. In order to further improve the heat dissipation efficiency, the fan blades 34 rotate under the drive of the motor 51, accelerate the flow of air in the connecting cover 33, take away the heat on the heat dissipation fins 32 more quickly and dissipate it into the air. In this way, the refrigeration fin 6 can work continuously and stably, and provide a continuous cooling effect for the water in the water tank 5.

[0054] By designing components such as the heat dissipation fins 32 and the fan blades 34, effective heat dissipation of the refrigeration plate 6 is achieved, thereby improving the refrigeration efficiency. This allows the water in the water tank to reach the required refrigeration temperature more quickly. The design of the heat dissipation mechanism fully takes the heat dissipation requirements of the refrigeration plate 6 into consideration, and by increasing the heat dissipation area and accelerating the air flow, etc., it is ensured that the refrigeration plate 6 can work continuously and stably, thereby enhancing the reliability and durability of the product.

[0055] In a further preferred embodiment of the present invention, a plurality of ventilation holes are provided on the connection cover 33 , dustproof nets are installed in the plurality of ventilation holes for preventing dust, and a soft pad 37 is installed on one side of the connection box 11 and the shell 2 .

[0056] In this embodiment, the vents are provided to ensure that air can flow smoothly into and out of the connection cover 33, thereby accelerating the heat dissipation on the heat dissipation fins 32. At the same time, the dustproof net can not only effectively block the entry of dust and debris, but also keep the vents unobstructed, ensuring the normal heat dissipation process;

[0057] In addition, soft pads 37 are installed on one side of the connection box 11 and the shell 2. The design of these soft pads 37 is mainly to increase the comfort of the user during use and prevent scratches or abrasions on the patient's face due to long-term use or improper operation. The setting of the vents and the installation of the dustproof net ensure that air can flow smoothly into and out of the connection cover 33, thereby accelerating the heat dissipation on the heat dissipation fins 32 and improving the heat dissipation efficiency. The existence of the dustproof net effectively blocks the entry of dust and debris, thereby extending the service life of the heat dissipation mechanism and the overall structure.

[0058] In a further preferred embodiment of the present invention, the top elastic band and the outer side of the shell 2 are both installed with a block 36 for limiting the hose 29, and one side of the four-corner elastic band 10 is installed with an anti-slip strip 38.

[0059] In this embodiment, the setting of the block 36 ensures that the hose 29 can be stably fixed on the elastic band on the top of the head and the shell 2 to prevent it from moving or falling off during use. Through the limiting effect of the block 36, the hose 29 can be firmly clamped, thereby ensuring the stability and reliability of its position. At the same time, this design can also ensure that the hose 29 will not affect the patient's line of sight, thereby improving the safety and practicality of the product. The design of the anti-slip strip 38 is mainly to increase the friction between the four-corner elastic band 10 and the patient's head to prevent unstable wearing or falling off due to sliding during use. Through the addition of the anti-slip strip 38, the four-corner elastic band 10 can better fit the patient's head, thereby improving the stability and comfort of wearing.

[0060] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0061] In another embodiment of the present invention, the elastic band assembly 1 is further provided with an annular frame 39, and the annular frame 39 is used for wearing on the ears without surgery. A fixing plate 40 is installed on the annular frame 39, and a sub-buckle of buckle 9 is installed on the fixing plate 40, and the sub-buckle is snap-connected with the female buckle of buckle 9 on the elastic band assembly 1.

[0062] In this embodiment, when the patient only needs to undergo surgery on one ear, the corresponding shell 2 can be removed, and then the ring frame 39 can be installed on the elastic band assembly 1. In this way, the patient can wear the shell 2 on one ear through the ring frame 39, which not only meets the fixation of the affected part of the ear, but also ensures the comfort and stability of wearing. By introducing the ring frame 39, the fixator can be applied to ear wearing scenarios without surgery, meeting the needs of more patients. At the same time, the design of the ring frame 39 can fit comfortably around the user's ear and provide stable support. Through the clamping method of the sub-button and the mother buckle, a quick and stable connection between the ring frame 39 and the elastic band assembly 1 is achieved, which is convenient for patients to adjust and replace according to their needs.

[0063] In another embodiment of the present invention, a frame 41 for myopic patients to wear is hingedly connected to one side of the four-corner elastic band 10 , and a replaceable lens 42 is detachably mounted on the frame 41 .

[0064] In this embodiment, when wearing the shell 2, the myopic patient can select and install suitable replaceable lenses 42 on the frame 41 according to his or her myopia degree. When glasses are needed, the frame 41 can be easily unfolded to provide a clear field of vision. When glasses are not needed, the frame 41 can be easily flipped upwards to avoid restrictions and interference with the patient's head movements. By introducing a flippable frame 41 without glasses legs and a replaceable lens 42 design, it can be suitable for myopic patients and meet their actual wearing needs. At the same time, the patient can select and install suitable lenses according to his or her myopia degree to ensure a clear field of vision when wearing. At the same time, the flip design of the frame also avoids interference with the patient's daily activities when not in use.

[0065] In another embodiment of the present invention, the shell 2 is equipped with an anti-compression mechanism for preventing the patient from compressing the shell 2 when sleeping, and the anti-compression mechanism includes: a small speaker 43 installed in the shell 2; a connecting tube 44 fixedly installed on the outside of the shell 2 and arranged in an inclined shape; a touch switch 45 installed in the connecting tube 44 for controlling the opening of the small speaker 43; a fixed plate 46 fixedly installed in the connecting tube 44, and a touch rod 47 for turning on the touch switch 45 is slidably installed on the fixed plate 46; a reset spring 48 mounted on the touch rod 47 for resetting the touch rod 47, and the two ends of the reset spring 48 are respectively fixedly connected to the fixed plate 46 and the touch rod 47.

[0066] In this embodiment, when the patient sleeps on his side, the head will drive the shell 2 to rotate together. If the shell 2 rotates to a position where it may be compressed, the touch rod 47 will contact the pillow and slide inward. This action will compress the reset spring 48 and make the touch rod 47 contact and trigger the touch switch 45. Once the touch switch 45 is triggered, the small speaker 43 will immediately sound a warning sound to alert the patient. Since the small speaker 43 is installed in the shell 2 with a certain sound insulation effect, the warning sound is enough to attract the patient's attention but will not interfere with other patients. Through timely warning sound reminders, the patient can make adjustments before inadvertently compressing the shell 2, avoiding possible discomfort. At the same time, the design of the anti-compression mechanism effectively prevents the potential risks caused by the patient's inadvertent compression of the shell 2, thereby effectively avoiding secondary injury to the affected part of the ear.

[0067] In another embodiment of the present invention, a storage box 49 for storing the elastic band assembly 1, the shell 2 and the mirror frame 41 is installed at the bottom of the water tank 5, a temperature sensor 52 for monitoring the water temperature in the water tank 5 is installed in the water tank 5, and a controller 53 for controlling the opening and closing of the refrigeration plate 6 and the refrigeration temperature is installed on one side of the water tank 5.

[0068] In this embodiment, when the user needs to use the fixator, the elastic band assembly 1, the shell 2, the frame 41 and other components can be taken out from the storage box 49 for assembly and wearing. At the same time, when the patient's ears need to be iced, the temperature sensor 52 will monitor the water temperature in the water tank 5 in real time and feed the data back to the controller 53. If the water temperature is higher than the appropriate range set by the user, the controller 53 will automatically start the cooling plate 6 for cooling. If the water temperature is already in the appropriate range or lower than the set value, the cooling plate 6 will remain in the off state to save energy. At the same time, the water pump 30 continuously supplies water to the shell 2. The design of the storage box 49 makes the product more tidy and orderly when not in use, avoiding the loss and damage of components.

[0069] In another embodiment of the present invention, a stirring mechanism for assisting water flow is installed in the water tank 5, and the stirring mechanism includes: a stirring rod 50 rotatably installed on one side of the inner wall of the box body 5; and a motor 51 fixedly installed on one side of the water tank 5 for driving the stirring rod 50 to rotate.

[0070] In this embodiment, when the user starts the motor 51, the output shaft of the motor 51 will drive the stirring rod 50 to start rotating. As the stirring rod 50 rotates, it will stir the water flow in the water tank 5 to form a vortex or turbulence, thereby increasing the uniformity and activity of the water flow, and helping to accelerate the uniform distribution of the water temperature.

[0071] In another embodiment of the present invention, a rectangular frame 54 is fixedly installed on the top of the water tank 5, and a storage rod 55 for storing the hose 29 is rotatably installed in the rectangular frame 54. The rotating shaft located on the left side of the storage rod 55 extends into the connecting cover 33. A group of U-shaped blocks 56 for fixing the two ends of the hose 29 are installed on the storage rod 55. The rotating shaft of the storage rod 55 and the stirring rod 50 are fixedly sleeved with sprocket 2 57, and the two sprockets 2 57 are sleeved with chains 2 58.

[0072] In this embodiment, when the water in the water tank 5 needs to be cooled, the user first starts the cooling plate 6 through the controller 53, and at the same time operates the hose 29 to disengage both ends of the hose from the U-shaped block 56. Then, the motor 51 is started, and the output shaft of the motor 51 drives the stirring rod 50 to start rotating. Since the stirring rod 50 and the storage rod 55 are both fixedly sleeved with a sprocket 57 and connected by a chain 58, the storage rod 55 will also rotate synchronously. As the storage rod 55 rotates, the hose 29 originally wrapped around it will be gradually released. Since the multiple hoses 29 are mutually engaged, After release, they need to be separated from each other. The separated hose 29 can be easily inserted into the pipe connection ends on the shell 2 and the water tank 5, thereby completing the connection of the refrigeration system. By designing the linkage system of the storage rod 55 and the stirring rod 50, the user can easily release and connect the hose 29 while starting the refrigeration system without performing additional operating steps. At the same time, the design of the storage rod 55 not only allows the hose 29 to be neatly stored when not in use, but also realizes the rapid release and connection of the hose 29 through the synchronous rotation mechanism, thereby improving the practicality and flexibility of the product.

[0073] In another embodiment of the present invention, the storage rod 55 and the fan blades 34 are provided with a connecting mechanism for synchronously driving the storage rod 55 and the fan blades 34 to rotate, and the connecting mechanism includes: a rotating rod 59 rotatably installed on the top of the inner wall of the link cover 33; a group of differential wheels 60 fixedly mounted on one end of the rotating rod 59 and the rotating shaft of the storage rod 55, and a group of differential wheels 60 are meshed with each other; a group of bevel differential gears 61 fixedly mounted on the other end of the rotating rod 59 and the rotating shaft of the fan blades 34, and a group of differential gears 61 are meshed with each other.

[0074] In this embodiment, when the motor 51 is started and drives the stirring rod 50 to rotate, since the stirring rod 50 is connected to the storage rod 55 through the sprocket 2 57 and the chain 2 58, the storage rod 55 will also rotate synchronously. At the same time, the rotating rod 59 is connected to the storage rod 55 through the differential wheel 60, so the rotating rod 59 will also rotate with the rotation of the storage rod 55. Subsequently, the rotating rod 59 is connected to the rotating shaft of the fan blade 34 through the bevel differential gear 61. Due to the differential setting of the bevel differential gear 61, the fan blade 34 can rotate at a speed higher than that of the storage rod 55. In this way, while the stirring rod 50 continues to stir the water, the fan blade 34 is also rotating at a high speed, realizing the heat dissipation operation of the refrigeration plate 6. Through the setting of the differential wheel 60 and the bevel differential gear 61, the fan blade 34 can rotate at a speed higher than that of the storage rod 55, thereby improving the heat dissipation efficiency of the fan blade 34 to the refrigeration plate 6 and the heat dissipation fin 32.

[0075] In another embodiment of the present invention, a protective cover for protecting the motor 51, the second sprocket 57 and the second chain 58 is fixedly installed on one side of the water tank 5, and a protective cover 62 for protecting the hose 29 from dust is hinged on the top of the protective cover, and magnet bars are installed on the bottom of the protective cover 62 and the rectangular frame 54, the two magnet bars are adsorbed on each other, and a handle 63 is installed on the top of the protective cover 62.

[0076] In this embodiment, when the hose 29 needs to be used, the user can easily flip open the protective cover 62 through the handle 63 to expose the connecting end of the hose 29. Then, the user can remove the hose 29 from the storage rod 55 and connect it to the corresponding pipe connecting end. When the hose 29 is not in use, the user can flip the protective cover 62 closed and firmly attach it to the rectangular frame 54 through the adsorption effect of the magnet bar, thereby preventing dust and impurities from entering the hose 29. At the same time, the presence of the protective cover can also effectively protect key components such as the motor 51, sprocket 2 57 and chain 2 58 from interference and damage from the external environment.

[0077] In summary, compared with the related art, the present fixator can better fix the gauze on the patient's ear through the setting of the shell and the water bag, and can also apply ice to the ear, thereby improving the soothing effect and helping to reduce postoperative discomfort.
