Description

Technical Field

[0001] The invention relates to the technical field of orthopedic emergency treatment, in particular to a portable fastening device for emergency treatment of fractures. Background Art

[0002] A fracture refers to a complete or partial break in a bone or bone structure. It is more common in children and the elderly, but it also occurs from time to time in young and middle-aged people. Patients often have a fracture in one part of the body, and a few have multiple fractures. With timely and appropriate treatment, most patients can recover their original functions, but a few patients may have sequelae of varying degrees. After a fracture occurs, those who are closer to the hospital can be sent directly to the hospital or call an ambulance. Patients who are far away from the hospital must undergo simple treatment to prevent their condition from worsening on the way to the hospital, or even cause irreversible consequences. When performing emergency treatment on patients with fractures, they need to be fixed with plaster and bandages to prevent dislocation between the bones, making it easier for doctors to put the bones back together.

[0003] Traditional fracture fixation devices can usually only provide static fixation support and cannot be dynamically adjusted according to the different diameters and lengths of the patient's limbs, making it difficult to meet the personalized needs of different patients. Conventional equipment requires a long time to install and adjust during use, especially in emergency situations. It cannot be deployed quickly. At the same time, the fixation method may only rely on belt constraints or external supports, which are insufficiently stable and prone to sliding or loosening. Conventional fracture fixation devices only focus on limb fixation and do not integrate other treatment functions. At the same time, the unreasonable design of the fixation components causes patients to feel uncomfortable or have obvious oppression when wearing them, while reducing the compression damage to the patient's skin and limbs caused by fixation. Conventional equipment requires cumbersome steps when removing, affecting the efficiency of emergency response. Summary of the Invention

The upper opposing frame 21 is away from the interior and is provided with an upper tight attachment 25 distributed in a straight line. The side wall of the opposing frame 21 is provided with an upper heater 26, and the side wall of the upper opposing frame 21 and the side close to the head end fixed head 1 are fixedly connected with a conversion hinge seat 27, and the conversion hinge seat 27 has an outward-opening shaft groove, and the end rotating shaft of the hydraulic output member 3 24 can be embedded in the shaft groove of the conversion hinge seat 27, and the open end of the shaft groove of the conversion hinge seat 27 is provided with a sliding elastic block 28, and a return spring structure is provided between the inner wall of the elastic block 28 and the conversion hinge seat 27. The opposing locking assembly includes a positioning rail 29 and a two-way curved rod 211 distributed on both sides. The positioning rail 29 is installed at the outer center of the upper opposing frame 21, and the positioning rail 29 track groove is provided with semicircular grooves 210 distributed linearly on both sides at the same time. The end has a curved structure, and the two sides rotate relative to each other on the side walls of the two-way curved rod 211. A locking slide 212 is slidably connected inside the positioning track 29. A two-way push rod 213 is connected between the two sides of the locking slide 212 and the curved structure of the two-way curved rod 211. A positioning column 214 is fixedly connected to the center of the inner wall of the two-way curved rod 211. A V-shaped aluminum sheet 215 is sleeved on the positioning column 214. The V-shaped aluminum sheet 215 is set to a V-shaped structure and has a wing structure relative to each other on both sides. A retaining spring 216 is embedded between the wing plates on both sides of the V-shaped aluminum sheet 215. The wing plates at both ends of the V-shaped aluminum sheet 215 away from the positioning column 214 are provided with semicircular blocks 217. The semicircular blocks 217 extend to the outside of the locking slide 212 and are connected to the semicircular grooves in the positioning track 29. 210 engage, the hydraulic output member 3 24 and the two-way hinge member 22 included in the limb root fixing mechanism 2 are hinged to each other with the L-shaped fixing frame 32 included in the limb outer end fixing mechanism 3, and the end of the hydraulic output member 3 24 will be separated from the conversion hinge seat 27 included in the limb root fixing mechanism 2 when folded. The conversion hinge seat 27 is a hinged rotating seat structure, and the open shaft groove provided inside it can be used for the end shaft of the hydraulic output member 3 24 to be embedded. When it is necessary to unfold the limb root fixing mechanism 2 and the limb outer end fixing mechanism 3, the end shaft of the hydraulic output member 3 24 is inserted into the shaft groove of the conversion hinge seat 27, and at the same time, the elastic block 28 installed at the open end of the shaft groove is pushed so that the elastic block 28 is pushed into the conversion hinge seat 27.Until the end shaft of the hydraulic output member 3 24 is completely embedded in the conversion hinge seat 27, the elastic block 28 will pop out along the opening of the shaft groove of the conversion hinge seat 27 under the action of the elastic force of the reset spring to seal the shaft groove of the conversion hinge seat 27, so that the hydraulic output member 3 24 is locked in the shaft groove of the conversion hinge seat 27 for rotation and cooperates with the expansion of the limb outer end fixing mechanism 3 structure. When it is not necessary to install, the elastic block 28 is manually pushed in so that the hydraulic output member 3 24 can be disengaged from the shaft groove of the conversion hinge seat 27, and then the limb outer end fixing mechanism 3 and the limb root fixing mechanism 2 are folded against each other to increase the portability of the device. When the patient uses it, the hydraulic output member 3 24 and the hydraulic output member 2 23 are opened so that the upper The opposing frame 21, the front tightening frame 31, and the L-shaped fixing frame 32 can be kept in a horizontal state as much as possible to match the straightness and stability of the patient's fractured limb. The upper arm part of the patient's fractured arm or the thigh part of the leg is tightened by the limb root fixing mechanism 2, and the upper arm part of the arm or the thigh part of the leg passes through the upper tightening belt 25 included in the limb root fixing mechanism 2. The upper arm part of the arm or the thigh part of the leg is fastened to the upper opposing frame 21 through the upper tightening belt 25. At the same time, the upper heater 26 installed on the upper opposing frame 21 can be used to perform heat therapy on the upper part to promote blood circulation and remove blood stasis, and the opposing locking component included in the limb root fixing mechanism 2 can be manually opened to strengthen the tightening state of the upper arm part of the arm or the thigh part of the leg. When the locking slide 212 is pushed along the positioning rail 29, the two-way push rods 213 on both sides of the locking slide 212 will simultaneously push the two-way curved rods 211 on both sides to rotate, so that the curved parts at both ends of the two-way curved rod 211 rotate while the two-way curved rods 211 rotate. The two sides are pressed tightly on the two ends of the upper arm part or the thigh part, and when the locking slide 212 slides along the positioning track 29, the locking structure of the internal locking slide 212 will engage and lock with the positioning track 29.

When the locking slide 212 is pushed to move, the semicircular blocks 217 will collide with the semicircular grooves 210 that engage in real time, and cause the V-shaped aluminum plate 215 to deform along the positioning column 214.The semicircular clamping block 217 will retract into the locking slide 212 until the locking slide 212 stops being pushed. The spring 216 installed between the wing structures on both sides of the V-shaped aluminum plate 215 will generate elastic force when the V-shaped aluminum plate 215 deforms, pushing the wing structures on both sides of the V-shaped aluminum plate 215 and the semicircular clamping block 217 out again. The semicircular clamping block 217 will re-engage with the semicircular clamping groove 210 at a corresponding pushing distance, so that the locking slide 212 is locked on the positioning track 29. At the same time, the rotation and clamping angle of the bidirectional curved rod 211 can be dynamically adjusted in real time according to the diameter of the upper arm or thigh.

[0025] Working principle: First, the portable fracture fastening device performs fast and portable limb fixation for fracture patients, and fixes the patient's fractured arm or leg through the limb root fixation mechanism 2 and the limb outer end fixation mechanism 3. The limb root fixation mechanism 2 and the limb outer end fixation mechanism 3 can also be folded, expanded or folded to achieve the effect of rapid deployment. The hydraulic output member 3 24 and the two-way hinge 22 contained in the limb root fixation mechanism 2 are hinged to the L-shaped fixing frame 32 contained in the limb outer end fixation mechanism 3. When the end of the hydraulic output member 3 24 is folded, it will be separated from the conversion hinge seat 27 contained in the limb root fixation mechanism 2. The conversion hinge seat 27 is an articulated rotating seat structure with an open rotating shaft arranged inside it. The groove can be used for the end rotating shaft of the hydraulic output component three 24 to be embedded. When it is necessary to expand the limb root fixing mechanism 2 and the limb outer end fixing mechanism 3, the end rotating shaft of the hydraulic output component three 24 is inserted into the rotating shaft groove of the conversion hinge seat 27, and the elastic block 28 installed at the open end of the rotating shaft groove is pushed at the same time, so that the elastic block 28 is pushed into the conversion hinge seat 27 until the end rotating shaft of the hydraulic output component three 24 is completely embedded in the conversion hinge seat 27. The elastic block 28 will pop out along the rotating shaft groove opening of the conversion hinge seat 27 under the action of the elastic force of the reset spring to seal the rotating shaft groove of the conversion hinge seat 27, so that the hydraulic output component three 24 is locked in the rotating shaft groove of the conversion hinge seat 27 for rotation, and cooperates with the expansion of the structure of the limb outer end fixing mechanism 3 without When installation is required, the elastic block 28 is manually pushed in so that the hydraulic output member 3 24 can be disengaged from the rotating shaft groove of the conversion hinge seat 27, and then the limb outer end fixing mechanism 3 and the limb root fixing mechanism 2 are folded against each other to increase the portability of the device. When the patient uses it, the hydraulic output member 3 24 and the hydraulic output member 2 23 are turned on so that the upper opposing frame 21 and the front tightening frame 31 and the L-shaped fixing frame 32 can be kept as horizontal as possible to match the straightness and stability of the patient's fractured limb. The upper arm part of the patient's fractured arm or the thigh part of the leg is fastened through the limb root fixing mechanism 2, and the upper arm part of the arm or the thigh part of the leg passes through the upper tightening attachment 25 included in the limb root fixing mechanism 2, and is fastened through the upper tightening attachment 25 The upper arm part of the arm or the thigh part of the leg is fastened to the upper opposing frame 21. At the same time, the upper heater 26 installed on the upper opposing frame 21 can be used to perform heat therapy on the upper part to promote blood circulation and remove blood stasis. The opposing locking component contained in the limb root fixing mechanism 2 is manually opened to strengthen the fastening state of the upper arm part of the arm or the thigh part of the leg. The positioning track 29 contained in the opposing locking component is installed on a fixed frame on one side of the upper opposing frame 21. A group of locking slides 212 are installed inside it for personnel to push and operate. The opposing locking component includes two groups of bidirectional curved rods 211 installed oppositely on the upper opposing frame 21. Both ends of the bidirectional curved rods 211 have a right-angle bend and are half-wrapped around the upper arm part of the arm or the thigh part of the leg.The two sides of the locking slide 212 are connected to the two-way curved rod 211 through a set of two-way push rods 213 respectively. When the locking slide 212 is pushed along the positioning track 29, the two-way push rods 213 on both sides of the locking slide 212 will simultaneously push the two-way curved rods 211 opposite to each other to rotate, so that the curved parts at both ends of the two-way curved rod 211 are pressed against the two ends of the upper arm part or the thigh part in a two-way manner while rotating. When the locking slide 212 slides along the positioning track 29, the locking structure of the locking slide 212 inside it will engage and lock with the positioning track 29. The positioning column 214 included in the locking structure is fixed inside the locking slide 212, and a set of V-shaped aluminum plates 215 are set on the outside. The V-shaped aluminum sheet 215 is deformed along the positioning column 214, and the semicircular block 217 is retracted into the locking slide 212 until the locking slide 212 stops being pushed. The retaining spring 216 installed between the wing plate structures on both sides of the V-shaped aluminum sheet 215 will generate elastic force when the V-shaped aluminum sheet 215 is deformed, and the wing plate structures on both sides of the V-shaped aluminum sheet 215 and the semicircular block 217 will be pushed out again, and the semicircular block 217 will re-engage with the semicircular block 217 of the corresponding pushing distance. The groove 210 is engaged, so that the locking slide 212 is locked on the positioning track 29, and at the same time, the rotation and pressing angle of the bidirectional curved rod 211 can be dynamically locked and adjusted in real time according to the upper arm part or the thigh part of the leg with different diameters, and the forearm part of the arm or the calf part of the leg is fastened and worn through the limb outer end fixing mechanism 3. After the forearm part of the arm or the calf part of the leg is inserted into the front tightening frame 31, the middle tightening frame 33 and the rear tightening frame 34 included in the limb outer end fixing mechanism 3 in turn, the middle tightening frame 33 and the rear tightening frame 34 are slid and adjusted according to the different characteristics of the elbow, mid-axis and wrist positions of the person's limb length, so that the middle tightening frame 33 and the rear tightening frame 34 installed on both sides of the middle tightening frame 3 are fastened and worn. The extension slide 35 slides along the built-in slide groove 36 installed inside the front tightening frame 31 and the rear tightening frame 34 to adjust according to the length of the fractured limb of the person. After the adjustment is completed, the limb tightening belt 37 installed inside the middle tightening frame 33, the front tightening frame 31 and the rear tightening frame 34 is used to fix the forearm part of the arm or the calf part of the leg in sequence, so that the patient's fractured limb fastening device can be quickly put on and quickly removed. The pressing and applying mechanism 4 is turned on. The pressing and applying mechanism 4 is a pressing transmission component for the arm part of the human body. The three outer ring pulleys 410 included in the two groups of pressing transmission components are evenly distributed in a ring around the central gear 49. A contact belt 412 is transmitted between the three outer ring pulleys 410.The contact belt 412 also extends to the user's skin surface through the inlay groove 1 39 and the inlay groove 2 310, wherein the two outer ring pulleys 410 are located at the bottom, so that the contact belt 412 sleeved between the two can contact the skin surface with the largest area, and an external gear ring 411 is also provided inside the outer ring pulley 410. One group is installed on the forearm part of the arm or the calf part of the leg where the middle tightening frame 33 is located through the rear side fixing frame 44 and the inlay groove 1 39, and the other group is installed on the forearm part of the arm or the calf part of the leg where the rear tightening frame 34 is located through the front side fixing frame 43 and the inlay groove 2 310. Then, the side wall motor of the rear side fixing frame 44 included in the pressing and applying mechanism 4 is turned on, so that the central gear 49 starts to rotate. The external gear ring 411 will drive the outer ring pulley 410 to rotate due to the meshing relationship with the central gear 49, so that the contact belt 412 drives the rubber column installed on the outer surface to continuously move at the patient's skin position. The two pressing transmission components are operated and massaged to activate blood circulation and remove blood stasis. When one pressing transmission component is in operation, the linkage sleeve 47 is driven to rotate. The linkage sleeve 47 is engaged with the linkage shaft 48 fixed to the other pressing transmission component by means of the built-in slide 414 installed on the linkage shaft 48. The external slide 413 installed on the linkage shaft 48 is engaged with the built-in slide 414, so that the two pressing transmission components are started and operated synchronously. The therapeutic liquid can also be injected through the drip irrigation tube 45 installed on the side wall of the rear fixing frame 44. The drip irrigation tube 45 is located above the pressing transmission component corresponding to the middle sleeve 33. The drip irrigation tube 45 can be transported to the drip irrigation tube 45 installed on the front fixing frame 43 through the connecting hose 46 installed on the output port. The two groups are respectively located above the two pressing transmission components. The therapeutic liquid will drip along the drip irrigation tube 45 onto the contact belt 412 corresponding to the pressing transmission component, and then be applied to the patient's skin by the contact belt 412. The synchronous dripping method is used to simultaneously improve the effect of applying the medicine and pressing and activating blood circulation.
