Description

Technical Field

[0002] A fracture is a complete or partial break in the continuity of bone structure. Leg fractures are relatively common in daily life and clinical practice.

[0003] Leg fracture fixation devices in related technologies use splints to immobilize the injured area.

Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. The drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0022] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application. However, it will be apparent to those skilled in the art that embodiments of the present application may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present application.

[0023] The implementation details of the technical solutions in the embodiments of this application are described in detail below: Reference Figures 1-3 As shown, the leg fracture fixation device includes at least a fixation component, which includes a first arc-shaped plate 1 and a second arc-shaped plate 2 arranged opposite to each other. The first arc-shaped plate 1 and the second arc-shaped plate 2 are connected by a detachable connector. A first airbag fixation component is fixedly installed on the inner side of the first arc-shaped plate 1, and a second airbag fixation component is fixedly installed on the inner side of the second arc-shaped plate 2. The first airbag fixation component and the second airbag fixation component are used to clamp and fix the leg. Both the first airbag fixation component and the second airbag fixation component adjust the clamping force on the leg by controlling the air intake.

[0024] In one embodiment of this application, when clamping and fixing the leg using the fixing components, the first arc plate 1 and the second arc plate 2 are respectively placed on both sides of the leg, and the first arc plate 1 and the second arc plate 2 are connected by a detachable connector. The leg is clamped and fixed by filling the first airbag fixing components and the second airbag fixing components with an appropriate amount of gas, thereby improving the stability and comfort of clamping and fixing the leg. Moreover, since the inflation volume of the first airbag fixing components and the second airbag fixing components is adjustable, it is suitable for use on multiple parts of the leg and does not need to strictly limit the thickness of the leg, thus having the characteristics of strong applicability.

[0025] In one embodiment of this application, the first airbag fixing assembly includes: an airbag body 4, which is fixedly connected to a first arc-shaped plate 1. A one-way inflation port 43 is provided at the end of the airbag body 4, and a solenoid valve is provided on the one-way inflation port 43. A probe of a pressure sensor 11 is fixedly installed on the outer surface area of ​​the airbag body 4 that contacts the leg. The pressure sensor 11 and the solenoid valve are both connected to a controller 12. The controller 12 is connected to a display 13. The pressure sensor 11, the controller 12, the display 13, and the solenoid valve are all connected to a rechargeable battery 14. The pressure sensor 11, the controller 12, the display 13, and the rechargeable battery 14 are all fixed to the outer surface of the first arc-shaped plate 1.

[0026] In one embodiment of this application, the first airbag fixing component and the second airbag fixing component have the same structure, and the structure of the second airbag fixing component will not be described in detail here. When the leg is clamped and fixed by the fixing component, the first arc plate 1 and the second arc plate 2 are respectively placed on both sides of the leg. The first arc plate 1 and the second arc plate 2 are connected by a detachable connector. The airbag body 4 on the first arc plate 1 and the airbag body 4 on the second arc plate 2 are inflated simultaneously by the air pump and the air inlet component until the probe of the pressure sensor 11 detects that the pressure value of the contact area between the airbag body 4 on the first arc plate 1 and the leg and the contact area between the airbag body 4 on the second arc plate 2 and the leg both reach the preset pressure range. Then the controller 12 controls the solenoid valve on the airbag body 4 on the first arc plate 1 to close and controls the solenoid valve on the airbag body 4 on the second arc plate 2 to close, thereby realizing the clamping effect on the leg and improving the fit and comfort of clamping the leg.

[0027] In one embodiment of this application, the controller 12 is further connected to a control keyboard, which includes an inflation start button and an inflation end button. The display 13 is used to display the pressure of the airbag body 4 on the first arc plate 1 against the leg contact area, and the pressure of the airbag body 4 on the second arc plate 2 against the leg contact area, during inflation of the airbag body 4 on the first arc plate 1 and the airbag body 4 on the second arc plate 2. This allows medical personnel to view the pressure values ​​of the airbag body 4 on the first arc plate 1 and the airbag body 4 on the second arc plate 2 against the leg contact area, and to manually control the start or end of inflation using the inflation start button and the inflation end button. The probe of the pressure sensor 11 is a patch probe and is fixed to the surface of the airbag body 4 by adhesive.

[0028] In one embodiment of this application, the airbag body 4 on the first arc-shaped plate 1 and the airbag body 4 on the second arc-shaped plate 2 are arranged opposite to each other, and the controller 12 is a microcontroller 12 or the like. The preset pressure range is the pressure range that meets the requirements for fracture fixation. In actual operation, a pressure value that the patient feels more comfortable can be selected within the pressure range required for fracture fixation, thereby improving the patient's comfort during the treatment process.

[0029] In one embodiment of this application, the inflation interface assembly is used to simultaneously deliver gas output from an inflation pump to different airbag bodies 4. That is, the air inlet end of the inflation interface assembly is connected to the air outlet end of the inflation pump, and the multiple air outlets 44 of the inflation interface assembly are respectively connected to the solenoid valves of different airbag bodies 4. The inflation interface assembly is a connector with gas diversion function.

[0030] In one embodiment of this application, a limiting strip 41 is fixedly installed on the outer surface edge of the airbag body 4 near the leg. The limiting strip 41 and the outer surface of the airbag body 4 near the leg form a receiving groove 42, which is used to place a cold compress or a hot compress.

[0031] In one embodiment of this application, in the early stages of a leg fracture, if swelling, bruising, or increased pain occur, cold compresses such as cold compresses are needed. During the recovery period of a leg fracture, hot compresses can be applied to the leg to accelerate blood circulation and promote recovery.

[0032] In one embodiment of this application, when the leg needs a cold compress, the first arc-shaped plate 1 and the second arc-shaped plate 2 are placed on both sides of the leg, and the cold compress bag is placed in the receiving groove 42. The first arc-shaped plate 1 and the second arc-shaped plate 2 are connected by a detachable connector. The airbag body 4 on the first arc-shaped plate 1 and the airbag body 4 on the second arc-shaped plate 2 are inflated simultaneously by an air pump and an air inflator assembly until the probe of the pressure sensor 11 detects that the pressure values ​​of the contact points between the airbag body 4 on the first arc-shaped plate 1 and the leg and the airbag body 4 on the second arc-shaped plate 2 both reach the preset pressure range. Then, the controller 12 controls the solenoid valve on the airbag body 4 on the first arc-shaped plate 1 to close and controls the solenoid valve on the airbag body 4 on the second arc-shaped plate 2 to close, thereby achieving the clamping effect on the leg and improving the fit and comfort of clamping the leg.

[0033] In one embodiment of this application, when the leg needs heat therapy, the first arc plate 1 and the second arc plate 2 are placed on both sides of the leg, and the heat pack is placed in the receiving groove 42. The first arc plate 1 and the second arc plate 2 are connected by a detachable connector. The airbag body 4 on the first arc plate 1 and the airbag body 4 on the second arc plate 2 are inflated simultaneously by an air pump and an air inflator assembly until the probe of the pressure sensor 11 detects that the pressure values ​​of the contact points between the airbag body 4 on the first arc plate 1 and the leg and the airbag body 4 on the second arc plate 2 both reach the preset pressure range. Then, the controller 12 controls the solenoid valve on the airbag body 4 on the first arc plate 1 to close and controls the solenoid valve on the airbag body 4 on the second arc plate 2 to close, thereby achieving the clamping effect on the leg and improving the fit and comfort of clamping the leg.

[0034] In one embodiment of this application, the limiting strip 41 is made of a flexible material. Even when the airbag body 4 on the first arc plate 1 and the airbag body 4 on the second arc plate 2 clamp the leg, the angle of the limiting strip 41 can be adjusted so that the inner side of the limiting strip 41 contacts the surface of the leg, without causing strong discomfort to the patient. The surfaces of the limiting strip 41 and the airbag body 4 can be provided with anti-slip stripes, anti-slip bumps, etc., to increase the friction between the cold compress or hot compress and the limiting strip 41, and between the cold compress or hot compress and the airbag body 4, reducing the probability of the cold compress or hot compress slipping out of the receiving groove 42 during the inflation of the airbag body 4. The cold compress or hot compress can also be attached to the outer surface of the airbag body 4 by providing adhesive backing to prevent it from slipping out of the receiving groove 42 during the inflation of the airbag body 4.

[0035] In one embodiment of this application, the number of airbag bodies 4 is set to multiple, and the number of pressure sensors 11 is set to multiple. Each airbag body 4 has a probe of a pressure sensor 11 fixedly installed on it. The multiple airbag bodies 4 clamp the legs by fully or partially inflating.

[0036] In one embodiment of this application, a pressure sensor 11 corresponds to an airbag body 4. Multiple airbag bodies 4 are provided on the first arc-shaped plate 1 and multiple airbag bodies 4 are provided on the second arc-shaped plate 2. Taking three airbag bodies 4 (left, middle, and right) on the first arc-shaped plate 1 and three airbag bodies 4 (left, middle, and right) on the second arc-shaped plate 2 as an example, when fixing the leg, the airbag body 4 in the middle position on the first arc-shaped plate 1 and the airbag body 4 in the middle position on the second arc-shaped plate 2 can be selected as a group. The airbag bodies 4 are located on both sides of the leg to fix it in place. Alternatively, the airbag bodies 4 on the left side of the first arc plate 1, the right side of the first arc plate 1, the left side of the second arc plate 2, and the right side of the second arc plate 2 can be grouped together to fix the upper left, lower left, upper right, and lower right areas of the leg. All the airbag bodies 4 on the first arc plate 1 and all the airbag bodies 4 on the second arc plate 2 can also be inflated to fix the leg. Multiple airbag combination methods are provided to facilitate selection according to actual needs.

[0037] In one embodiment of this application, after the leg is fixed for a predetermined time using one airbag combination method, another airbag combination method can be switched to fix the leg. By changing the airbag combination method, the fixation position of the leg can be changed. On the one hand, this helps to reduce skin damage and discomfort caused by the airbag body 4 clamping the same leg area for a long time. On the other hand, changing the airbag combination method facilitates the replacement of cold compresses or hot compresses without affecting the fixation effect on the leg. For example, before changing the airbag combination method, a cold compress or hot compress is placed on the airbag body 4 of the latter airbag combination method. After the airbag body 4 of the latter airbag combination method reaches the required inflation level, the cold compress or hot compress of the airbag body 4 of the latter airbag combination method can be used to apply cold or hot compresses to the leg, and the airbag body 4 of the former airbag combination method is deflated. When the airbag body 4 of the former airbag combination method is detached from the leg, the cold compress or hot compress can be removed, realizing the replacement of the cold compress or hot compress.

[0038] In one embodiment of this application, each airbag body 4 is provided with an air outlet 44, and the airbag body 4 in the latter airbag combination method is deflated by opening the air outlet 44. During the inflation process of each airbag body 4, the air outlet 44 is in a closed state.

[0039] In one embodiment of this application, the first arc plate 1 and the second arc plate 2 are rotatably connected by a rotating shaft 3, and an elastic pad is fixedly installed on the rotating shaft 3.

[0040] In one embodiment of this application, when the first arc plate 1 and the second arc plate 2 are respectively placed on both sides of the leg, the elastic pad reduces the discomfort caused by the leg directly contacting the pivot 3. The elastic pad can be made of rubber or silicone.

[0041] In one embodiment of this application, the elastic pad includes an elastic support block 31 and a flexible pad 32. One end of the elastic support block 31 is fixedly connected to the rotating shaft 3, and the other end of the elastic support block 31 is fixedly connected to the flexible pad 32.

[0042] In one embodiment of this application, the elastic support block 31 can be a shock-absorbing block or a support block made of a flexible material, and the flexible pad 32 can be made of a flexible material, such as silicone or rubber.

[0043] In one embodiment of this application, the elastic support block 31 is provided to support the flexible pad 32. When the first arc plate 1 and the second arc plate 2 are placed on both sides of the leg, the leg contacts the flexible pad 32 and squeezes the flexible pad 32, thereby causing the elastic support block 31 to press down or push up the rotating shaft 3, causing the first arc plate 1 and the second arc plate 2 to close, which facilitates operation.

[0044] In one embodiment of this application, an assembly is provided on the second arc plate 2, which is used to combine multiple fixed components in a manner that is either fixed in relative position or variable in relative position.

[0045] In one embodiment of this application, one or more fixation components can be selected as needed. When there are multiple fixation components (e.g., one fixation component is located above the knee and another fixation component is located below the knee), the fixation components can be combined and connected by assemblies. The assemblies can be combined and connected in the following ways: in a relative position fixation manner and in a relative position variable manner. The relative position fixation manner is suitable for the initial stage of treatment of a patient's fracture, when the patient's leg needs to be fixed to avoid displacement. The relative position variable manner is suitable for the stage when the patient's fracture has recovered to a certain extent and needs to undergo rehabilitation training or appropriate activities.

[0046] In one embodiment of this application, the assembly includes a switching component and a locking block 25. The switching component is used to switch the combination mode among multiple fixed components. The locking block 25 is slidably connected to the second arc plate 2 and is used to lock the switching component after the multiple fixed components are combined.

[0047] In one embodiment of this application, before combining multiple fixing components, the multiple fixing components are placed at different positions on the leg, and the second arc-shaped plates 2 of the multiple fixing components are placed on the same side of the leg. By sliding the locking block 25, the locking block 25 is moved away from the switching component. The switching component combines and connects the multiple fixing components in a variable relative position or a fixed relative position manner. Then, the locking block 25 is slid closer to the switching component, and the switching component is locked by the blocking action of the locking block 25. When it is necessary to change the combination method between the multiple fixing components, the locking block 25 is slid away from the switching component, and the locking block 25 loses its locking effect on the switching component. The switching component switches between the variable relative position manner and the fixed relative position manner to combine and connect the multiple fixing components. Then, the locking block 25 is slid closer to the switching component, and the switching component is locked by the blocking action of the locking block 25.

[0048] In one embodiment of this application, the switching component includes: a knob 21, a first rack 23 and a second rack 24 located on both sides of the knob 21, the knob 21 being rotatably connected to a second arc-shaped plate 2, the first rack 23 and the second rack 24 being slidably connected to the second arc-shaped plate 2, a locking block 25 being slidably connected to the second arc-shaped plate 2, a drive gear 22 being coaxially connected to the knob 21, the drive gear 22 being drivenly connected to the first rack 23 and the second rack 24, a limit block 231 being fixedly installed at one end of the first rack 23, a slot 232 being provided in the limit block 231, the slot 232 being adapted to the other end of the first rack 23, and both ends of the second rack 24 being arc-shaped.

[0049] In one embodiment of this application, when multiple fixing components need to be combined and connected in a relatively fixed manner, the locking blocks 25 on the multiple fixing components are moved to a position away from the knob 21. The knob 21 is rotated to drive the drive gear 22 to rotate. The rotation of the drive gear 22 drives the first rack 23 and the second rack 24 to move away from each other, so that the first racks 23 in the two fixing components are brought closer to each other. One end of one first rack 23 is placed in the slot 232 provided at the end of the other first rack 23. Through the cooperation between the slot 232 and the end of the first rack 23, the two first racks 23 are ensured to be on the same straight line, and the included angle between the two first racks 23 is prevented from changing. This ensures the fixation of the relative position between the two fixing components, which is beneficial to strengthening the fixation effect on the legs. When one end of one first rack 23 is placed in the slot 232 provided at the end of the other first rack 23, the locking blocks 25 on both fixing components are moved to a position close to the knob 21 until the locking blocks 25 are placed in the meshing space (the space area of ​​adjacent teeth) of the drive gear 22, preventing the drive gear 22 from continuing to rotate, thereby locking the knob 21.

[0050] In one embodiment of this application, multiple fixing components need to be combined and connected in a variable relative position. The locking blocks 25 on the multiple fixing components are moved to a position away from the knob 21. Rotating the knob 21 drives the drive gear 22 to rotate. The drive gear 22 rotates, causing the first rack 23 and the second rack 24 to move away from each other, bringing the second racks 24 of the two fixing components closer together until their ends contact. Since the ends of the two second racks 24 are arc-shaped, the contact between their ends changes the angle between the two first racks 23, satisfying the need for proper leg movement (e.g., knee joint). When the ends of the two second racks 24 contact, the locking blocks 25 on both fixing components are moved closer to the knob 21 until the locking blocks 25 are placed in the meshing space of the drive gear 22 (the space between adjacent teeth), preventing the drive gear 22 from continuing to rotate and locking the knob 21.

[0051] In one embodiment of this application, when it is necessary to switch the fixing method between multiple fixing components, the first rack 23 and the second rack 24 can be moved forward or backward by rotating the knob 21 in both directions, thereby realizing the connection between the two first racks 23 or the connection between the two second racks 24.

[0052] In one embodiment of this application, the detachable connector includes a Velcro 15 and a hook 26. The Velcro 15 is fixedly connected to the first arc-shaped plate 1, and the hook 26 is fixedly connected to the second arc-shaped plate 2.

[0053] In one embodiment of this application, when the first arc-shaped plate 1 and the second arc-shaped plate 2 need to be fixed, one end of the Velcro 15 is passed through the hook 26 and glued together with the other end of the Velcro 15 to achieve a fixed connection between the first arc-shaped plate 1 and the second arc-shaped plate 2. The Velcro 15 and the hook 26 are arranged in pairs, and the paired Velcro 15 and the hook 26 can be a single pair or multiple pairs.

[0054] In one embodiment of this application, the method of using the leg fracture fixation device includes: placing a first arc plate 1 and a second arc plate 2 on both sides of the leg, placing multiple airbag bodies 4 on one side of the leg and multiple airbag bodies 4 on the other side of the leg, simultaneously inflating the multiple airbag bodies 4 on the first arc plate 1 and the multiple airbag bodies 4 on the second arc plate 2 by means of an air pump and an air inflator assembly, and detecting the pressure value between each airbag body 4 and the contact part of the leg by means of a pressure sensor 11. When the pressure value between each airbag body 4 and the contact part of the leg is within a preset pressure range, the controller 12 controls the solenoid valves provided on the multiple airbag bodies 4 to close, thereby completing the clamping of the leg.

[0055] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
