DETAILED DESCRIPTION

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" in the specification and claims of the present application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions. 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.

[0032] 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.

[0033] The embodiment of the present invention provides an orthopedic splint mounting and fastening device, such as Figure 1-11 As shown, the orthopedic splint installation and fastening device includes: a supporting slide 1, on which a bidirectional adjustment screw 2 is rotatably installed, and the bidirectional adjustment screw 2 has two threaded sections with opposite rotation directions, and sliding seats 3 are respectively threadedly sleeved on the two threaded sections, and both of the sliding seats 3 are in sliding contact with the top of the supporting slide 1; the tops of the two sliding seats 3 are fixedly installed with sleeves 5 using multiple supporting legs 4, and the two sleeves 5 can provide multiple fixed splints 6 and patient arms or legs for extending, and the two sleeves 5 are provided with multiple vacuum splint adsorption and fixing mechanisms for adsorbing and fixing the inserted fixed splints 6, and the multiple vacuum splint adsorption and fixing mechanisms are evenly distributed in a circular array along the sleeves 5; a vacuum source air guide mechanism, which is connected to the multiple vacuum splint adsorption and fixing mechanisms for controlling vacuum adsorption or release.

[0034] In this embodiment, when in use, first, the medical staff needs to adjust the distance between the two sleeves 5 by rotating the bidirectional adjustment screw 2 according to the size of the patient's arm or leg and the required length of the fixed splint 6. Since the bidirectional adjustment screw 2 has two threaded sections with opposite rotation directions, when the screw rotates, the two sliding seats 3 will slide toward or away from each other along the top of the supporting slide 1, thereby realizing the rapid adjustment of the distance between the sleeves 5. Subsequently, the medical staff uses the vacuum splint adsorption and fixing mechanism to adsorb and fix the fixed splint 6. During adsorption, the vacuum source air guide mechanism is used to suck out the air in the vacuum splint adsorption and fixing mechanism to form a vacuum environment; since the vacuum splint adsorption and fixing mechanism is evenly distributed in a circular array along the sleeves 5, the same fixed splint 6 is located on the vacuum splint adsorption and fixing mechanism on the same straight line of the two sleeves 5.

[0035] After ensuring that the fixed splint 6 is stably adsorbed, the medical staff inserts the patient's arm or leg into the two sleeves 5 so that it is located between the multiple fixed splints 6. At this time, since the fixed splint 6 has been fixed by vacuum adsorption, the patient's arm or leg will be stably supported and fixed, which is convenient for subsequent orthopedic treatment.

[0036] The orthopedic splint mounting and fastening device of the present invention realizes rapid adjustment of the spacing between the sleeves 5 through the design of the bidirectional adjustment screw 2 and the sliding seat 3, so that it can adapt to patients' arms or legs of different sizes and fixed splints 6 of different lengths. At the same time, this scheme adopts a vacuum splint adsorption and fixing mechanism to fix the fixed splint 6, and does not limit the width of the fixed splint 6. Therefore, it can adapt to fixed splints 6 of various widths. This design not only improves the versatility of the device, but also makes the installation process simpler and faster.

[0037] The vacuum splint adsorption and fixing mechanism is used to adsorb and fix the fixed splint 6, which has a strong adsorption force and uniform force distribution. This fixing method can ensure that the fixed splint 6 will not loosen or pop out during the installation process, thereby greatly improving the stability and safety of the treatment. At the same time, the vacuum adsorption technology also avoids the discomfort and injury risks that may be caused by traditional manual binding and fixation.

[0038] In a further preferred embodiment of the present invention, the vacuum splint adsorption and fixing mechanism includes an adjustable air pipe 7, a suction cup seat 8 and a suction cup cover 9, the adjustable air pipe 7 is slidably installed on the sleeve 5, the suction cup seat 8 is arranged in the sleeve 5 and is connected to the adjustable air pipe 7, the suction cup cover 9 is fixedly installed on the suction cup seat 8, and is used to adsorb and fix the splint 6, and the suction cup seat 8 and the suction cup cover 9 are both connected to the adjustable air pipe 7.

[0039] In this embodiment, when in use, the adjustable air pipe 7 is slidably installed on the sleeve 5 to ensure that its position can be easily adjusted when needed. The suction cup seat 8 is arranged inside the sleeve 5 and is closely connected with the adjustable air pipe 7 to ensure smooth transmission of gas. The suction cup cover 9 is fixedly installed on the suction cup seat 8, and its shape and size are designed just right to fit closely and firmly absorb and fix the clamp 6.

[0040] When the fixed splint 6 needs to be adsorbed, the suction cup seat 8 and the suction cup cover 9 are aligned with the position of the splint to be fixed. Then, the vacuum source air guide mechanism is started, and a vacuum environment is quickly formed inside the suction cup cover 9, generating a strong adsorption force to tightly adsorb the fixed splint 6. Since the shape and size of the suction cup cover 9 match the fixed splint 6, the stability and firmness of the adsorption can be ensured. After that, the medical staff can first control the contact between the fixed splint 6 and the patient by adjusting the position of the adjustable airway 7 to complete the position adjustment.

[0041] The sliding design of the adjustable trachea 7 makes the vacuum splint adsorption and fixation mechanism more flexible and accurate during use. Medical staff can easily adjust the position of the adjustable trachea 7 according to the specific conditions of the patient and the position of the fixed splint 6, thereby achieving accurate adsorption and fixation of the fixed splint 6.

[0042] The close fit between the suction cup seat 8 and the suction cup cover 9, as well as the smooth transmission of the adjustable air tube 7, make the vacuum splint adsorption and fixing mechanism more stable and safe. During the adsorption process, the suction cup cover 9 can fit tightly against the fixed splint 6, generating a uniform adsorption force, ensuring that the fixed splint 6 will not loosen or pop out during the installation process. At the same time, by adjusting the position of the adjustable air tube 7, medical staff can further control the contact degree and position of the fixed splint 6 with the patient's arm or leg, thereby ensuring the stability and safety of the fixation.

[0043] By adjusting the position of the adjustable trachea 7, medical staff can more accurately control the contact between the fixed splint 6 and the patient's arm or leg, thereby avoiding unnecessary compression and discomfort. This design not only improves the patient's comfort, but also helps to improve the treatment effect and patient satisfaction.

[0044] In summary, the further optimized vacuum splint adsorption and fixation mechanism of the present invention realizes accurate, stable and safe adsorption and fixation of the fixed splint 6 through the close cooperation and flexible adjustment of the adjustable air tube 7, the suction cup seat 8 and the suction cup cover 9. At the same time, the mechanism also provides higher flexibility and accuracy, as well as stronger stability and safety, providing patients with a more comfortable and optimized treatment experience.

[0045] In a further preferred embodiment of the present invention, the vacuum source air guiding mechanism includes a vacuum pump 10, and the suction pipe 11 of the vacuum pump 10 is connected to a horizontal connecting pipe 12, and the horizontal connecting pipe 12 is connected to two vertical connecting pipes 13, and the two vertical connecting pipes 13 are each connected to a plurality of conducting pipes 14, and the plurality of conducting pipes 14 are respectively connected to the plurality of adjustable air pipes 7 on the vacuum splint adsorption and fixing mechanisms, and the plurality of conducting pipes 14 are each provided with a pressure relief valve 15.

[0046] In this embodiment, the mechanism is mainly composed of a vacuum pump 10, an air suction pipe 11, a horizontal connecting pipe 12, two vertical connecting pipes 13, multiple conducting pipes 14 and multiple pressure relief valves 15. The vacuum pump 10 is connected to the horizontal connecting pipe 12 through the air suction pipe 11, and the horizontal connecting pipe 12 is further connected to the two vertical connecting pipes 13. Each vertical connecting pipe 13 is connected to multiple conducting pipes 14, which are respectively connected to the adjustable air pipes 7 on the multiple vacuum clamp adsorption and fixing mechanisms. A pressure relief valve 15 is provided on each conducting pipe 14 to release the gas in the vacuum environment when needed.

[0047] In actual operation, when the splint 6 needs to be adsorbed and fixed, the medical staff first starts the vacuum pump 10, and the vacuum pump 10 extracts the air in the horizontal connecting pipe 12 through the suction pipe 11 to form a vacuum environment. Subsequently, this vacuum environment is transmitted to the adjustable air pipe 7 on each vacuum splint adsorption and fixing mechanism through two vertical connecting pipes 13 and multiple conducting pipes 14, thereby forming a vacuum inside the suction cup cover 9, generating a strong adsorption force, and adsorbing the fixed splint 6 tightly on the suction cup cover 9.

[0048] During the adsorption process, if the medical staff finds that the adsorption force of a certain fixing splint 6 is too large or needs to be adjusted, they can release part of the gas in the vacuum environment by opening the pressure relief valve 15 on the corresponding conducting pipe 14, thereby reducing the adsorption force. They can also release the fixing splint 6 after the fixation is completed to allow the patient to be detached. This design not only improves the flexibility and safety of the device, but also enables the medical staff to accurately control the adsorption force according to the actual situation.

[0049] In a further preferred embodiment of the present invention, the vacuum splint adsorption and fixing mechanism also includes an adjusting screw 16, which is threadedly sleeved on the outside of the adjustable air pipe 7 and rotatably connected to the sleeve 5, and a guide groove 17 is opened on the side of the adjustable air pipe 7. A guide frame 18 is fixedly mounted on the sleeve 5, and the guide frame 18 extends into the guide groove 17.

[0050] In this embodiment, the adjusting screw 16 is threadedly sleeved on the outside of the adjustable air tube 7 and is rotatably connected to the sleeve 5. This design allows medical personnel to adjust the position of the adjustable air tube 7 in the sleeve 5 by rotating the adjusting screw 16 while keeping the adjustable air tube 7 connected to the sleeve 5.

[0051] In order to further enhance the stability of the adjustable air pipe 7, a guide groove 17 is provided on its side, and a guide frame 18 is fixedly mounted on the sleeve 5. The guide frame 18 extends into the guide groove 17 to form a sliding guide structure, which not only limits the rotation of the adjustable air pipe 7, but also ensures its linear movement during the adjustment process, thereby improving the accuracy and stability of the adjustment.

[0052] In actual operation, the medical staff first rotates the adjusting screw 16 to adjust the position of the adjustable air tube 7 according to the specific conditions of the patient and the position of the fixed splint 6. Due to the sliding guiding effect of the guide groove 17 and the guide frame 18, the adjustable air tube 7 can move smoothly in the sleeve 5 until it reaches the ideal adsorption position.

[0053] In a further preferred embodiment of the present invention, a screw sleeve 19 is fixedly provided on any one of the adjusting screw barrels 16 in the plurality of vacuum clamping plate adsorption and fixing mechanisms on the two sleeves 5 for operating rotation.

[0054] In this embodiment, in the multiple vacuum clamping plate adsorption fixing mechanisms on the two sleeves 5, a screw sleeve 19 is fixedly sleeved on any adjusting screw barrel 16. The design purpose of the screw sleeve 19 is to facilitate the medical staff to operate and rotate the adjusting screw barrel 16, thereby adjusting the position of the adjustable airway 7.

[0055] The screw sleeve 19 is usually made of wear-resistant and non-slip material to ensure that the medical staff can operate easily and stably during rotation. At the same time, the fixed sleeve arrangement of the screw sleeve 19 also ensures a tight connection between it and the adjusting screw barrel 16, avoiding possible loosening or slipping during rotation.

[0056] In actual operation, the medical staff first determine the adjustment screw 16 that needs to be adjusted by observing the specific condition of the patient and the position of the fixed splint 6. Then, they can hold the screw sleeve 19 by hand and rotate the adjustment screw 16 easily and stably to adjust the position of the adjustable airway 7 in the sleeve 5.

[0057] Due to the wear-resistant and anti-slip properties of the screw sleeve 19 and the tight connection between the screw sleeve 19 and the adjusting screw barrel 16, medical staff can feel obvious resistance feedback during the rotation process, which helps them to control the rotation angle and strength more accurately.

[0058] In a further preferred embodiment of the present invention, a plurality of the adjustable air pipes 7 are fixedly sleeved with a conical toothed disc 20, a plurality of shaft sleeves 21 are fixedly mounted on the two sleeves 5, both ends of the plurality of shaft sleeves 21 are provided with shaft seats 22 fixedly connected to the corresponding sleeves 5, a plurality of transmission flexible shafts 23 are rotatably mounted in the plurality of shaft sleeves 21, both ends of the plurality of transmission flexible shafts 23 are fixedly mounted with rotating shafts 24, the plurality of rotating shafts 24 are respectively rotatably connected to the corresponding shaft seats 22, a plurality of rotating shafts 24 are fixedly mounted with bevel gears 25, and the plurality of bevel gears 25 are respectively meshed with the corresponding conical toothed discs 20, so that the plurality of adjusting screws 16 located on the same sleeve 5 rotate synchronously.

[0059] In this embodiment, conical toothed discs 20 are fixedly mounted on the plurality of adjustable air pipes 7 . The conical toothed discs 20 are designed to achieve synchronous rotation of the plurality of adjusting screw barrels 16 .

[0060] At the same time, a plurality of sleeves 21 are fixedly installed on the two sleeves 5, and both ends of these sleeves 21 are provided with shaft seats 22 fixedly connected to the corresponding sleeves 5. Transmission flexible shafts 23 are rotatably installed in the sleeves 21, and both ends of these transmission flexible shafts 23 are fixedly installed with rotating shafts 24, and these rotating shafts 24 are rotatably connected to the corresponding shaft seats 22.

[0061] Bevel gears 25 are fixedly mounted on the rotating shaft 24, and these bevel gears 25 are respectively meshed with corresponding bevel toothed discs 20. This design enables that when the medical staff rotates one of the adjusting screw barrels 16, the transmission of the bevel toothed disc 20 and the bevel gears 25 can drive the other adjusting screw barrels 16 on the same sleeve 5 to rotate synchronously.

[0062] In actual operation, the medical staff first determines the adjustment screw barrel 16 that needs to be adjusted, and rotates the screw sleeve 19 by hand. Due to the meshing relationship between the conical toothed disc 20 and the conical gear 25, when an adjustment screw barrel 16 is rotated, the transmission flexible shaft 23 and the rotating shaft 24 connected thereto will be driven to rotate.

[0063] The rotation of the rotating shaft 24 will further drive the bevel gear 25 thereon to rotate, and the rotation of the bevel gear 25 will drive the rotation of other bevel toothed discs 20 through the meshing relationship. In this way, all the adjusting screw barrels 16 on the same sleeve 5 will achieve synchronous rotation through the transmission of the bevel toothed discs 20 and the bevel gears 25.

[0064] In a further preferred embodiment of the present invention, the adjustable air pipe 7 has a threaded adjustment section 26 at one end of the suction cup seat 8, and an adjusting screw sleeve 27 is threadedly sleeved on the threaded adjustment section 26. The adjusting screw sleeve 27 is connected to the suction cup seat 8 by an adaptive adjustment mechanism.

[0065] In the present embodiment, a threaded adjustment section 26 is added to one end of the adjustable air tube 7 located at the suction cup seat 8. The threaded adjustment section 26 is designed so that an adjustment screw sleeve 27 can be threadedly sleeved thereon. By adding the threaded adjustment section 26 and the adjustment screw sleeve 27, the present invention realizes fine adjustment of the connection between the adjustable air tube 7 and the suction cup seat 8. When the distances between different fixed splints 6 and the patient's body are different, the adjustment screw sleeve 27 can be rotated to make the lengths of each suction cup seat 8 and the suction cup cover 9 different from the adjustable air tube 7. An adaptive adjustment mechanism is used to connect the adjustment screw sleeve 27 to the suction cup seat 8. The design of this adaptive adjustment mechanism is intended to achieve a flexible and stable connection between the adjustment screw sleeve 27 and the suction cup seat 8, while allowing fine adjustment as needed.

[0066] In a further preferred embodiment of the present invention, the adaptive adjustment mechanism includes an adaptive sliding sleeve 28, which is slidably mounted on the adjusting screw sleeve 27 and fixedly mounted on the suction cup seat 8. The adaptive sliding sleeve 28, the suction cup seat 8 and the end of the threaded adjustment section 26 constitute an adaptive air guide cavity 29. The adjustable air pipe 7, the threaded adjustment section 26, the inner cavity of the adjusting screw sleeve 27, the adaptive air guide cavity 29, the suction cup seat 8 and the suction cup cover 9 are sequentially connected. The outer fixed sleeve of the adjusting screw sleeve 27 is provided with a load-bearing ring 30. A plurality of sliding holes 31 are opened on the adaptive sliding sleeve 28, and T-shaped sliding rods 32 are slidably installed in the plurality of sliding holes 31. The ends of the plurality of T-shaped sliding rods 32 are fixedly connected to the load-bearing ring 30. The plurality of T-shaped sliding rods 32 are provided with reset springs 33, and the two ends of the reset spring 33 respectively conflict with the load-bearing ring 30 and the adaptive sliding sleeve 28.

[0067] In this embodiment, the adaptive adjustment mechanism includes an adaptive sliding sleeve 28, which is a tubular structure that can be slidably sleeved on the adjusting screw sleeve 27 and fixedly sleeved on the suction cup seat 8. The design of the adaptive sliding sleeve 28 not only ensures the flexible connection between the adjusting screw sleeve 27 and the suction cup seat 8, but also realizes the adaptive air guide function through its special structure.

[0068] Specifically, the adaptive sliding sleeve 28, the suction cup seat 8 and the end of the threaded adjustment section 26 together form an adaptive air guide cavity 29. The design of this adaptive air guide cavity 29 enables the adjustable air pipe 7, the threaded adjustment section 26, the inner cavity of the adjustment screw sleeve 27, the adaptive air guide cavity 29, the suction cup seat 8 and the suction cup cover 9 to be connected in sequence, thereby ensuring the smooth flow of gas.

[0069] In addition, a bearing ring 30 is fixedly sleeved outside the adjusting screw sleeve 27, which is a ring-shaped structure for supporting and fixing the T-shaped slide bar 32. A plurality of slide holes 31 are provided on the adaptive sliding sleeve 28, and a T-shaped slide bar 32 is slidably installed in each slide hole 31. The ends of these T-shaped slide bars 32 are fixedly connected to the bearing ring 30, thereby ensuring a stable connection between the adjusting screw sleeve 27 and the adaptive sliding sleeve 28.

[0070] More importantly, a return spring 33 is sleeved on each T-shaped slide bar 32. The two ends of these return springs 33 are respectively in contact with the load ring 30 and the adaptive sliding sleeve 28. Their design not only provides necessary elastic support, but also can maintain close contact and flexible connection between the adaptive sliding sleeve 28 and the adjusting screw sleeve 27 through the elastic force of the return spring 33 when the adjusting screw sleeve 27 rotates or moves.

[0071] In actual application, when the fixed splint 6 contacts the patient, while the contact continues, the suction cup cover 9 and the fixed splint 6 remain in place. Due to the reaction, the adaptive sliding sleeve 28 slides on the adjusting screw sleeve 27. Due to the existence of the sliding hole 31, the adaptive sliding sleeve 28 slides along the T-shaped sliding rod 32 and compresses the reset spring 33.

[0072] In a further preferred embodiment of the present invention, a device seat 34 is provided below the support slide 1 , and a plurality of moving wheels 35 are installed at the bottom of the device seat 34 .

[0073] In this embodiment, a device seat 34 is added below the support slide 1. The device seat 34 serves as a supporting platform, and a plurality of moving wheels 35 are installed at the bottom thereof. These moving wheels 35 are usually made of wear-resistant and anti-slip materials to ensure the stability and mobility of the device on different ground surfaces.

[0074] Specifically, the moving wheel 35 is connected to the bottom of the device seat 34 through a solid bracket to ensure that it will not fall off or be damaged during movement. At the same time, the moving wheel 35 is also equipped with a locking device so that the position of the device can be fixed when needed to prevent it from sliding or rolling.

[0075] In practical applications, the combination of the device base 34 and the moving wheels 35 brings significant convenience to the entire device. Medical staff can easily move the entire device to a desired position by pushing or pulling. During the movement, the smooth rolling of the moving wheels 35 reduces friction and resistance, making the movement easier and faster.

[0076] When the device reaches the designated position, the medical staff can fix the moving wheel 35 through the locking device to ensure that the device will not move or slide due to external force during use. In this way, not only the stability and safety of the treatment process are guaranteed, but also the working efficiency of the medical staff is improved.

[0077] In a further preferred embodiment of the present invention, the inner wall of the adaptive sliding sleeve 28 is in sealing sliding contact with the outer wall of the adjusting screw sleeve 27, and the adjustable air pipe 7, threaded adjustment section 26, adjusting screw sleeve 27, adaptive sliding sleeve 28, suction cup seat 8 and suction cup cover 9 are arranged in sequence along the outer side of the sleeve 5 to the inner side.

[0078] In this embodiment, the adjustable gas pipe 7 is used as the source of gas input and is connected to the adjusting screw sleeve 27 through the threaded adjustment section 26. The adjusting screw sleeve 27 is flexibly connected to the adaptive sliding sleeve 28 through the sealing sliding contact between its outer wall and the inner wall of the adaptive sliding sleeve 28. The adaptive sliding sleeve 28 is further fixedly connected to the suction cup seat 8, and the suction cup seat 8 is connected to the suction cup cover 9 through the internal channel thereof, thereby completing the construction of the entire gas transmission path.

[0079] In practical applications, the sealed sliding contact between the adaptive sliding sleeve 28 and the adjusting screw sleeve 27 ensures that the gas will not leak during the transmission process, thereby ensuring the stability and safety of the treatment. At the same time, this design also allows medical staff to adjust the position of the adaptive sliding sleeve 28 by rotating the adjusting screw sleeve 27, thereby achieving fine adjustment of the length of the gas channel between the suction cup seat 8 and the suction cup cover 9.

[0080] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0081] In another embodiment of the present invention, a telescopic sleeve 36 is fixedly installed on the top of the device seat 34, a telescopic plate 37 is slidably installed inside the telescopic sleeve 36, the top of the telescopic plate 37 is fixedly connected to the bottom of the supporting slide 1, and a resisting bolt is threadedly installed on the telescopic sleeve 36 for resisting and fixing the telescopic plate 37, thereby fixing the length of the telescopic sleeve 36 and the telescopic plate 37.

[0082] In this embodiment, a telescopic sleeve 36 is added to the top of the device seat 34, and a telescopic plate 37 is slidably installed inside the telescopic sleeve 36, and the top of the telescopic plate 37 is firmly connected to the bottom of the support slide 1. This design allows the telescopic plate 37 to slide freely in the telescopic sleeve 36, thereby realizing flexible adjustment of the height.

[0083] In addition, a conflicting bolt is cleverly threadedly installed on the telescopic sleeve 36, and the main function of this bolt is to conflict with and fix the telescopic plate 37, thereby locking the relative length between the telescopic sleeve 36 and the telescopic plate 37. The design of the conflicting bolt is not only simple and practical, but also can ensure that after the position of the telescopic plate 37 is adjusted, the entire device can remain stable without accidental sliding or displacement.

[0084] In practical applications, medical staff can change the relative height between the support slide 1 and the device seat 34 according to specific needs by adjusting the sliding position of the telescopic plate 37 in the telescopic sleeve 36. This adjustment method is not only convenient and fast, but also can accurately meet the use requirements in different scenarios.

[0085] In another embodiment of the present invention, the vacuum pump 10 is disposed on a device base 34 , a control box 38 is fixedly mounted on the device base 34 , and the control box 38 is connected to the vacuum pump 10 .

[0086] In this embodiment, the vacuum pump 10 is disposed on the device base 34. At the same time, a control box 38 is fixedly mounted on the device base 34. The control box 38 is closely connected with the vacuum pump 10 through an internal circuit, thereby realizing precise control of the vacuum pump 10.

[0087] Specifically, the vacuum pump 10 is a core component that provides a negative pressure source, and the stability of its performance is directly related to the working effect of the entire device. Therefore, in this embodiment, we directly install the vacuum pump 10 on the device base 34, and the stable support provided by the device base 34 ensures the stability and reliability of the vacuum pump 10 during operation.

[0088] The control box 38 serves as the control center of the entire device, and integrates a variety of control elements and circuits, which can realize various control functions such as starting, stopping, and speed regulation of the vacuum pump 10. At the same time, the control box 38 also has a variety of protection mechanisms such as overcurrent, overvoltage, and overheating, ensuring the safe operation of the vacuum pump 10 under complex working conditions.

[0089] In actual applications, medical staff can easily remotely control the vacuum pump 10 by operating the control panel on the control box 38 or input devices such as a remote controller. For example, when the vacuum pump 10 needs to be started to generate negative pressure, the medical staff only needs to press the start button on the control box 38, and the vacuum pump 10 will quickly start and start working. Similarly, when the vacuum pump 10 needs to be stopped or its working parameters need to be adjusted, the medical staff can also achieve this through corresponding operations.

[0090] In addition, the control box 38 also has the functions of fault alarm and status display, etc. When the vacuum pump 10 fails or works abnormally, the control box 38 will immediately send out an alarm signal and display the corresponding fault information so that the medical staff can take timely measures to deal with it.

[0091] In another embodiment of the present invention, a guide ring 39 is fixedly sleeved on both of the two sleeves 5, a rotating ring 40 is rotatably sleeved on both of the two sleeves 5, an assembly seat 41 is fixedly installed on both of the two rotating rings 40, an axial rod clamping seat 42 is fixedly installed on both of the two assembly seats 41, and a first gauze sleeve rod 43 and a second gauze sleeve rod 44 are respectively clamped on the two shaft rod clamping seats 42 for sleeve-loading a gauze roll, and the first gauze sleeve rod 43 and the second gauze sleeve rod 44 are slidably connected and can adjust the length.

[0092] In this embodiment, a guide ring 39 and a rotating ring 40 are added to both sleeves 5. The guide ring 39 is fixedly mounted on the sleeve 5, and plays a role of positioning and guiding, ensuring the stability and accuracy of the sleeve 5 during the rotation or sliding process. The rotating ring 40 is rotatably mounted on the sleeve 5, allowing it to rotate freely on the sleeve 5, thereby realizing flexible adjustment of the assembly seat 41 and subsequent components.

[0093] The assembly seat 41 is fixedly mounted on the rotating ring 40, and serves as a bridge connecting the shaft rod holder 42. The design is stable and easy to operate. The shaft rod holder 42 is respectively provided with a first gauze sleeve rod 43 and a second gauze sleeve rod 44. The design of the two gauze sleeve rods allows the gauze roll to be put on, thereby meeting the actual needs of the part between the two sleeves 5, the fixed splint 6 and the patient's arm or leg wrapped with gauze during the medical process. It is worth noting that the first gauze sleeve rod 43 and the second gauze sleeve rod 44 are connected by sliding, which means that their lengths can be adjusted as needed, further enhancing the flexibility and practicality of the device.

[0094] In practical applications, medical staff can adjust the position and angle of the assembly seat 41 and the shaft holder 42 by rotating the rotating ring 40 according to the specific needs of the patient and the needs of the medical process. This adjustment method can meet the needs of winding gauze.

[0095] At the same time, the sliding connection design between the first gauze sleeve rod 43 and the second gauze sleeve rod 44 allows medical staff to flexibly adjust their lengths according to the size and length of the gauze roll. This design not only improves the utilization rate of the gauze, but also avoids the inconvenience caused by insufficient gauze length during medical treatment.

[0096] By adding the guide ring 39 and the rotating ring 40, and adopting the sliding connection between the first gauze sleeve rod 43 and the second gauze sleeve rod 44, the present embodiment significantly enhances the flexibility and practicality of the device. Medical staff can more conveniently adjust the position, angle and length of the gauze sleeve rod, thereby meeting the use requirements in different scenarios.

[0097] The sliding connection design between the first gauze sleeve rod 43 and the second gauze sleeve rod 44 can meet the adaptability requirements of the two sleeves 5 when adjusting the spacing.

[0098] In another embodiment of the present invention, the first gauze sleeve rod 43 and the second gauze sleeve rod 44 are fixedly installed with end blocks 45 at their ends away from each other, and the two end blocks 45 respectively abut against the sides of the two shaft rod holders 42 away from each other, and the first gauze sleeve rod 43 and the second gauze sleeve rod 44 are both threadedly sleeved with assembly locking nuts 46, and the two assembly locking nuts 46 respectively abut against the other side of the corresponding shaft rod holder 42 away from the end blocks 45, and the first gauze sleeve rod 43 and the second gauze sleeve rod 44 are both threadedly sleeved with gauze limiting nuts 47 for limiting the gauze roll.

[0099] In this embodiment, end blocks 45 are fixedly installed at the ends of the first gauze sleeve rod 43 and the second gauze sleeve rod 44 that are away from each other. The two end blocks 45 are respectively against the sides of the two shaft rod holders 42 that are away from each other, thereby playing an effective limiting role on the gauze sleeve rod.

[0100] In addition, the first gauze sleeve rod 43 and the second gauze sleeve rod 44 are both threadedly sleeved with assembly locking nuts 46. The two assembly locking nuts 46 respectively abut against the other side of the corresponding shaft rod holder 42 away from the end block 45. By tightening the assembly locking nuts 46, we can firmly fix the gauze sleeve rod on the shaft rod holder 42 to ensure its stability and reliability during the medical process.

[0101] In order to meet the effective limit demand for the gauze roll, gauze limit nuts 47 are threadedly sleeved on the first gauze sleeve rod 43 and the second gauze sleeve rod 44. The design of the two gauze limit nuts 47 allows medical staff to flexibly adjust their positions according to the size and length of the gauze roll, thereby achieving effective limit and fixation of the gauze roll.

[0102] In practical applications, medical personnel can first put the gauze roll on the first gauze sleeve rod 43 or the second gauze sleeve rod 44, and then adjust the position of the gauze limiting nut 47 as needed to make it tightly contact one side of the gauze roll, thereby effectively limiting the gauze roll. Then, the medical personnel can tighten the assembly locking nut 46 to firmly fix the gauze sleeve rod on the shaft holder 42 to ensure its stability and reliability during the medical process.

[0103] In addition, due to the design of the end block 45, the position of the gauze sleeve rod on the shaft rod holder 42 is effectively restricted, thereby preventing the gauze sleeve rod from sliding or falling off during the medical treatment process. This design not only improves the safety of the medical treatment process, but also allows medical staff to focus more on the treatment of patients, thereby improving work efficiency.

[0104] In another embodiment of the present invention, an annular guide groove 48 is formed on the two guide rings 39, and a rotating slide 49 is rotatably installed in the two annular guide grooves 48. The two rotating slides 49 are respectively fixedly connected to the two assembly seats 41, and an annular tooth 50 is fixedly installed on the outer ring of at least one of the guide rings 39. A motor 51 is fixedly installed on the assembly seat 41 corresponding to the annular tooth 50, and a circular gear 52 is fixedly installed on the output shaft of the motor 51, and the circular gear 52 is meshed with the annular tooth 50.

[0105] In this embodiment, an annular guide groove 48 is provided on both guide rings 39, and the design of the two annular guide grooves 48 provides a track for the installation and sliding of the rotating slide 49. The two rotating slides 49 are respectively rotatably installed in the corresponding annular guide grooves 48, and are fixedly connected to the two assembly seats 41. This design enables the assembly seat 41 and its subsequent components (such as the shaft rod holder 42, the gauze sleeve rod, etc.) to rotate and slide stably under the guidance of the guide ring 39.

[0106] In addition, an annular tooth 50 is fixedly mounted on the outer ring of at least one guide ring 39, and this design is to realize the automatic rotation of the assembly seat 41 and its subsequent components. A motor 51 is fixedly mounted on the assembly seat 41 corresponding to the annular tooth 50, and a circular gear 52 is fixedly mounted on the output shaft of the motor 51. The circular gear 52 is meshed with the annular tooth 50. When the motor 51 is started, the circular gear 52 will drive the annular tooth 50 and the corresponding guide ring 39 to rotate, and then drive the entire gauze winding device to rotate through the rotating slide 49 and the assembly seat 41.

[0107] In practical applications, medical staff can adjust the rotation angle of the assembly seat 41 and its subsequent components (such as the shaft holder 42, the gauze sleeve rod, etc.) by starting the motor 51 according to the specific needs of the patient and the needs of the medical process. The start of the motor 51 will drive the circular gear 52 to rotate, and since the circular gear 52 is meshed with the annular teeth 50, the annular teeth 50 and the corresponding guide ring 39 will also rotate accordingly. This rotation will be transmitted to the entire gauze winding device through the rotating slide 49 and the assembly seat 41, thereby achieving accurate adjustment of its rotation angle.

[0108] In this solution, the motor 51 can be powered by a battery and operated by wireless connection control.

[0109] To sum up, compared with the relevant technology, the present device adopts a vacuum splint adsorption and fixing mechanism to adsorb and fix the fixed splint 6. The adsorption and fixing method can meet the needs of fixing splints 6 of various widths, and has high fixation adaptability. At the same time, it can also ensure that the fixed splint 6 will not loosen or pop out during the installation process, thereby greatly improving the stability and safety of treatment.
