Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and more specifically, to a nursing device for emergency tibia and fibula fractures. Background Technology
[0002] The tibia and fibula are the bones of the tibia and fibula, located in the leg. Single tibial shaft fractures, double tibial shaft fractures, and single fibular shaft fractures are the most common fractures in the body. Due to their close proximity and the fact that injuries often occur concurrently, they are collectively referred to as tibial and fibular fractures. Tibial and fibular fractures are the most common long bone fractures, with a high incidence rate, and can occur at any age. In children with greenstick fractures and adults with simple tibial fractures, local swelling and tenderness are relatively mild, and movement is not significantly restricted; walking is still possible. If there is significant displacement of the fracture, it can manifest as obvious deformity, abnormal movement, and crepitus. Current postoperative care for tibial and fibular fractures involves elevating the affected limb to promote venous blood return, thereby reducing edema and pain and promoting wound healing.
[0003] In emergency treatment, plaster cast immobilization and calcaneal traction are the main methods of treatment. Although plaster cast immobilization can provide basic support, it is difficult to adapt to the inevitable swelling changes of the injured limb. During the peak of swelling, it may cause excessive compression. Because the rigidity of plaster cast immobilization cannot adapt to the dynamic swelling changes of the injured limb, there is a risk of compressing blood vessels and nerves during the peak of swelling. After the swelling subsides, it may lose its immobilization effect due to loosening. Therefore, we propose an emergency tibial and fibular fracture care device. Summary of the Invention

Detailed Implementation
[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0024] Example 1 further illustrates the nursing device for emergency tibia and fibula fractures proposed in this invention, which includes a protective cover 100. The side wall of the protective cover 100 is hinged to an adhesive plate 101. One end of the adhesive plate 101 is installed on the outside of the protective cover 100 via Velcro. Locking blocks 102 are symmetrically fixedly connected to the outside of the protective cover 100. A linkage plate 103 is fixedly connected between the two locking blocks 102. A linkage rope 104 is threaded through the two sets of locking blocks 102. An arc-shaped groove 105 is provided on the outside of the protective cover 100. An arc plate 106 is slidably connected to the outside of the arc-shaped groove 105. Multiple sets of screws 107 are threaded between the linkage plate 103 and the arc plate 106. A protective plate 108 is fixedly connected to the outside of the arc plate 106. A groove 109 is formed in the protective plate 108. Depend on Figures 1 to 5 It is known that the shield 100 is semi-circular and is used to place the patient's tibia and fibula. The shield 100 is filled with memory foam, which has good cushioning and breathability and does not affect the breathability and heat dissipation of the person's legs. When the memory foam comes into contact with the patient's legs, it can adjust according to the shape of the human body to provide comfortable support. Furthermore, the outer bottom of the protective cover 100 is provided with an arc-shaped groove 105, and an arc-shaped plate 106 is slidably connected to the outer side of the arc-shaped groove 105. The sliding distance of the arc-shaped plate 106 is limited. At the same time, the device is fixedly connected to a linkage plate 103 on the outer side of the protective cover 100 by two sets of locking blocks 102. Multiple sets of screws 107 are threaded between the linkage plate 103 and the arc-shaped plate 106. In this way, the position of the screws 107 can be adjusted as needed to lock and release the arc-shaped plate 106. Traditional fixation devices often require a certain amount of space or allowance for adjustment of tightness. However, as the swelling gradually subsides, the gap between the device and the limb increases, resulting in a significant reduction in fixation pressure and a greatly diminished fixation effect. Micromovement or even displacement of the fracture ends may occur, affecting the healing process. The tricky part is that, in order to maintain sufficient fixation stability, the fixation device is sometimes deliberately tied too tightly. This device has a semi-circular protective plate 108 fixedly connected to the outside of the arc plate 106. An adjustment mechanism 200 for caring for the tibia and fibula is set inside the protective plate 108. The adjustment mechanism 200 includes a drive component 201 set on the protective plate 108, an abutment component 202 set at the bottom of the drive component 201, multiple sets of sliding components 203 set in the slot 109, and a care component 204 set in a circular shape on the inner side of the slot 109. The abutment component 202 and the sliding component 203 cooperate to adjust the care component 204. It also includes an auxiliary mechanism 300 disposed in the slot 109. The auxiliary mechanism 300 includes a fixing member 301 disposed in the inner wall of the slot 109, a pressing member 302 disposed in the fixing member 301, and a rotating member 303 disposed in the inner side of the slot 109. The rotating member 303 and the pressing member 302 cooperate to reduce the local tissue temperature, promote the contraction of superficial blood vessels, and reduce local blood exudation and tissue fluid generation.
[0025] Working principle: When using this device, the patient's leg is placed inside the protective cover 100, and a linkage rope 104 is connected to the outside of the protective cover 100. The linkage rope 104 can be installed on the device. By moving the linkage rope 104 in the vertical direction, the height of the patient's leg can be adjusted. Then, the position of the protective plate 108 can be adjusted as needed. Simply rotate the arc plate 106 to the appropriate position, and the position of the arc plate 106 can be locked by three sets of screws 107. When the patient's leg is swollen, the patient only needs to adjust the mechanism 200. Sufficient space is provided at the swollen area. When the swelling subsides, the adjustment mechanism 200 returns the device to its original position. The spring's rebound force pushes the nursing plate 204a to continue adhering to the skin, maintaining stable support and improving patient comfort. The invention also includes an auxiliary mechanism 300, which, through linkage, allows the low-temperature gas from the fixing cylinder 301a to blow onto the swollen area. Its core function is similar to ice packs, namely, by lowering the local tissue temperature, it causes superficial blood vessels to constrict, reducing local blood exudation and tissue fluid production, thereby helping to inhibit further swelling.
[0026] Example 2 Based on Embodiment 1, the following technical features are added: The adjustment mechanism 200 includes a driving component 201, a contact component 202 is provided at the bottom end of the driving component 201, multiple sets of sliding components 203 are provided in the slot 109, and a care component 204 is provided circumferentially on the inner side of the slot 109. The driving component 201 includes a mounting bracket 201a that can be detachably installed on the upper end face of the protective plate 108. A motor 201b is detachably installed on the upper end face of the mounting bracket 201a by bolts. A rotating rod 201c is fixedly connected to the rotor shaft end of the motor 201b. A gear 201d is keyed to the outer wall of the rotating rod 201c. An arc-shaped strip 201e is fixedly connected to the upper end face of the protective plate 108. A rack 201f is fixedly connected to the inner wall of the arc-shaped strip 201e. The gear 201d meshes with the rack 201f. A gear 201g is fixedly connected to one end of the rotating rod 201c located in the slot 109. Depend on Figures 1 to 9It can be seen that the mounting bracket 201a is U-shaped, and the motor 201b is detachably installed in the middle of the U-shape facing upward. The rotor shaft end of the motor 201b is fixedly connected to the rotating rod 201c. The upper and lower ends of the rotating rod 201c are respectively connected to gear 1 201d and gear 2 201g. The motor 201b is regulated by an external controller. The motor 201b drives gear 1 201d on the outer wall of the rotating rod 201c to rotate. Since gear 1 201d meshes with rack 1 201f, it drives the outer arc strip 201e of rack 1 201f to rotate. The abutting member 202 includes a connecting strip 202a that is linearly fixedly connected to the bottom end of the arc-shaped strip 201e. Multiple sets of connecting strips 202a are fixedly connected to the bottom ends of abutting plates 202b. The outer wall of the abutting plate 202b is integrally formed with a variable diameter portion 202c. The sliding member 203 includes a sliding plate 203a that is circumferentially disposed in the protective plate 108. A sliding groove 203b is formed in the sliding plate 203a. A slot 203c is formed on one side of the sliding groove 203b. A bearing seat 203d is rotatably connected to one end of the sliding plate 203a. The variable diameter portion 202c is in contact with the slot 203c. Depend on Figures 2 to 8 It can be seen that the bottom end of the arc-shaped strip 201e is fixedly connected to multiple sets of connecting strips 202a, and the bottom end of the multiple sets of connecting strips 202a is fixedly connected to a contact plate 202b. The contact plate 202b is arc-shaped, and multiple sets of variable diameter parts 202c are integrally formed on the outer side of the contact plate 202b. The arc-shaped strip 201e drives the contact plate 202b to rotate synchronously through the multiple sets of connecting strips 202a. While the contact plate 202b rotates, it drives the variable diameter parts 202c to rotate. At the same time, a sliding plate 203a moves horizontally inside the protective plate 108. A long strip-shaped sliding groove 203b is formed inside the sliding plate 203a. A slot 203c is formed at the end of the sliding groove 203b. The variable diameter parts 202c contact the slot 203c accordingly. Thus, under the action of the variable diameter parts 202c, the sliding plate 203a is driven to move horizontally. In practical use, the motor 201b drives the gear 201d on the outer wall of the rotating rod 201c to rotate. The gear 201d meshes with the rack 201f, thereby driving the outer arc-shaped bar 201e of the rack 201f to rotate. The arc-shaped bar 201e drives the contact plate 202b to rotate synchronously through multiple sets of connecting bars 202a. While the contact plate 202b rotates, it also drives the variable diameter part 202c to rotate. Since the variable diameter part 202c abuts against the slide plate 203a, it drives the slide plate 203a to move outward. If the variable diameter part 202c does not contact the slide plate 203a, the slide plate 203a will move inward under the action of the tension spring 204b. The nursing component 204 includes a nursing plate 204a that is circumferentially hinged to the slot 109, and multiple sets of bearing seats 203d are rotatably connected at one end to the back of the nursing plate 204a. Tension springs 204b are symmetrically fixedly connected to the back of the nursing plate 204a. The tension springs 204b are carbon springs with high strength and are easy to use in daily work. One end of the multiple sets of tension springs 204b is fixedly connected to the inner side of the slot 109. A gap area 204c is formed between adjacent nursing plates 204a. Figures 3 to 8 It can be seen that the slot 109 is semi-circular, and four sets of nursing plates 204a are hinged inside the slot 109. The nursing plates 204a are made of soft rubber, and one end of the sliding plate 203a is rotatably connected to the back of the nursing plate 204a through the bearing 203d. The nursing plate 204a is composed of multiple independent small pressure plate units. Each unit is connected to a tension spring 204b on the back. When the affected limb is swollen, the soft tissue pressure increases. The adjusting mechanism 200 pushes the variable diameter part 202c to push the sliding plate 203a, thereby driving the nursing plate 204a to move outward to provide space for the swelling. When the swelling subsides, the spring's rebound force will push the nursing plate 204a to continue to adhere to the skin. Working principle: During use, when the patient experiences swelling, the patient simply activates the motor 201b via the external controller. The motor 201b drives the rotating rod 201c to rotate, which in turn drives gears 201d and 201g to rotate synchronously. Gear 201d meshes with rack 201f, thereby causing the outer arc-shaped strip 201e of rack 201f to rotate. The arc-shaped strip 201e, through multiple sets of connecting strips 202a, drives the contact plate 202. When the contact plate 202b rotates synchronously, it drives the variable diameter part 202c to rotate. Since the variable diameter part 202c abuts against the slide plate 203a, it drives the slide plate 203a to move outward. This causes the nursing plate 204a to rotate at the hinge point, providing space for the swollen area. If the variable diameter part 202c does not contact the slide plate 203a, the slide plate 203a will move inward under the action of the tension spring 204b, thereby maintaining a stable fixing pressure.
[0027] Example 3 Based on Embodiment 2, the following technical features are added: The auxiliary mechanism 300 includes a fixing member 301 disposed on the inner wall of the slot 109, a pressing member 302 disposed inside the fixing member 301, a rotating member 303 disposed on the inner side of the slot 109, the fixing member 301 includes a fixing cylinder 301a circumferentially fixedly connected to the inner wall of the slot 109, a cavity 301b formed inside the fixing cylinder 301a, an air outlet 301c formed on the outer side of the fixing cylinder 301a, the cavity 301b communicating with the air outlet 301c, a piston plate 301d movably connected to the inner wall of the cavity 301b, a compression spring 301e fixedly connected to the side wall of the piston plate 301d, one end of the compression spring 301e fixedly connected to the inner wall of the cavity 301b, a movable rod 301f fixedly connected to the side wall of the piston plate 301d, and an inclined groove 301g formed on the outer wall of the movable rod 301f; Depend on Figures 3 to 8 It can be seen that a cylindrical structure is formed inside the fixed cylinder 301a and the cavity 301b. An ice pack is placed inside the cavity 301b. A piston plate 301d is slidably connected inside the cavity 301b. The piston plate 301d is connected to the side wall of the cavity 301b by a compression spring 301e. A movable rod 301f is fixedly connected to one end of the piston plate 301d. Six sets of air outlets 301c are evenly provided on the outer side of the fixed cylinder 301a. The air outlets 301c are connected to the cavity 301b. An inclined groove 301g is formed on the outer wall of the movable rod 301f. The movable rod 301f moves horizontally by the movement of the pressing member 302 in the vertical direction. The pressing component 302 includes a pressing plate 302a that moves vertically within a fixed cylinder 301a. A pressing rod 302b is fixedly connected to the upper end face of the pressing plate 302a. A vertical plate 302c is integrally formed at the bottom end of the pressing plate 302a. An auxiliary frame 302d is fixedly connected to the bottom end of the vertical plate 302c. A pressing block 302e is fixedly connected to the inner wall of the auxiliary frame 302d. A push spring 302f is fixedly connected to the bottom end of the auxiliary frame 302d. The bottom end of the push spring 302f is fixedly connected to the cavity. At the bottom end of 301b, the pressing block 302e abuts against the upper end of the inclined groove 301g. The rotating part 303 includes a limiting groove 303a at the top of the inner side of the slot 109. An auxiliary ring 303b is rotatably connected to the bottom end of the limiting groove 303a. A rack 2 303c is fixedly connected to the outer wall of the auxiliary ring 303b. Gear 2 201g meshes with rack 2 303c. A wave surface 303d is formed at the bottom end of the auxiliary ring 303b. The pressing rod 302b abuts against the lower end of the wave surface 303d. Depend on Figures 1 to 8It can be seen that the bottom end of the pressing plate 302a is fixed with an auxiliary frame 302d by a pressing rod 302b and a vertical plate 302c. The bottom end of the auxiliary frame 302d is fixed to the upper end face of the bottom end of the cavity 301b by a push spring 302f. Since the bottom end of the auxiliary ring 303b has a wave surface 303d, when the auxiliary ring 303b rotates, its wave surface 303d gives the pressing rod 302b a downward force, or under the action of the push spring 302f, it drives the pressing plate 302a to move upward. Since the pressing block 302e on the inner side of the pressing plate 302a abuts against the upper end face of the inclined groove 301g, it drives the movable rod 301f to move horizontally, so that the gas in the fixed cylinder 301a is blown toward the swollen part of the patient. A notch 303e is formed inside the auxiliary ring 303b, and a wave surface 303f is formed inside the notch 303e. Multiple sets of auxiliary rods 303g move vertically inside the protective cover 100. The bottom end of the auxiliary rod 303g abuts against the upper end surface of the wave surface 303f. An auxiliary spring 303h is sleeved on the outer wall of the auxiliary rod 303g. The auxiliary spring 303h is a carbon spring and is fixedly connected to the bottom end of the protective cover 100. Memory foam is provided inside the protective cover 100. As the auxiliary ring 303b rotates, it will drive the wave surface 303f to rotate synchronously. At this time, the bottom end of the auxiliary rod 303g abuts against the upper surface of the wave surface 303f. The auxiliary ring 303b will give the auxiliary rod 303g an upward force, or move downward under the action of the auxiliary spring 303h. Because memory foam has good cushioning and breathability, it can adjust according to the shape of the human body after contacting the leg under pressure, providing comfortable support and improving the patient's comfort.
[0028] Working principle: When the patient is swollen, the adjustment mechanism 200 provides a comfortable space for the patient. As shown in Example 2, when the rotating rod 201c rotates, it drives the gear 201g to rotate. Since the gear 201g meshes with the rack 303c, the rack 303c drives the auxiliary ring 303b to rotate. When the auxiliary ring 303b rotates, its wave surface 303d applies a downward force to the pressure rod 302b, or under the action of the push spring 302f, it drives the pressing plate 302a to move upward. Since the pressing block 302e on the inner side of the pressing plate 302a abuts against the upper end face of the inclined groove 301g, it drives the movable rod 301f to move horizontally. In this way, the gas in the fixed cylinder 301a is blown towards the swollen part of the patient, causing superficial blood vessels to constrict, reducing local blood exudation and tissue fluid production, thereby helping to inhibit the further development of swelling.
