Description

Technical Field

[0001] The utility model belongs to the technical field of orthopedic rehabilitation instruments, and particularly relates to a multifunctional external fixation brace for osteoporotic fractures. Background Art

[0002] Osteoporosis is a type of fracture caused by reduced bone density and deterioration of bone tissue microstructure. It is usually closely related to age growth and hormonal changes. Especially with the increase of age, the bone mass gradually decreases, and the annual disappearance rate of bone mass is 0.5%-1%. This natural trend makes the elderly prone to osteoporosis. At the same time, the calcium intake in the diet of the elderly is insufficient, resulting in a negative net absorption balance. In order to maintain the blood calcium balance, calcium must be mobilized from the bones into the blood, which will also lead to a decrease in bone density, resulting in osteoporosis, and further leading to osteoporotic fractures.

[0003] When suffering from osteoporotic fractures, it is necessary to go to the hospital for corrective treatment. After the treatment, the affected limb of the patient needs to be fixed and protected. However, when using the existing plaster fixation method for protection, due to the low bone density of osteoporotic patients, using this method may cause compression and burden on the arm or leg, which may lead to skin pressure sores and deep vein thrombosis. Moreover, the plaster has poor air permeability, which may cause skin ulcers and other problems. Therefore, it is necessary to propose an external fixation brace that can cause less compression on the affected limb. Content of the Utility Model

[0004] In order to solve the problem of the compression of the external fixation brace on the affected limb, the purpose of the utility model is to provide a multifunctional external fixation brace for osteoporotic fractures. The affected limb can be fixed and protected through the fixing belt, and then the affected limb can be supported and attached by the airbag layer and the ellipsoidal heat dissipation balls to reduce the burden on the arm or leg of the fracture patient.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows: a multifunctional external fixation brace for osteoporotic fractures, including a front fixing plate, the inner wall of the front fixing plate is provided with a first airbag layer, the front fixing plate is rotatably connected with a rear fixing plate, both sides of the outer walls of the front fixing plate and the rear fixing plate are fixedly connected with a plurality of fixing belts, the inner wall of the rear fixing plate is provided with a second airbag layer, both sides of the front fixing plate and the rear fixing plate opposite to the fixing belts are provided with a plurality of fixing buckles, and the surfaces of the first airbag layer and the second airbag layer are both provided with a plurality of dense ellipsoidal heat dissipation balls.

[0006] The principle of the basic solution is as follows: First, place the affected limb of the patient into the front fixing plate and the rear fixing plate. Since the airbag layer is fixedly connected to the inner wall of the fixing plate, and there are dense ellipsoidal heat dissipation balls on the surface of the airbag layer, when the affected limb is placed into the fixing plate, the affected limb will fit with the ellipsoidal heat dissipation balls, and the airbag layer plays an auxiliary supporting role. Then, fix and contract the fixing plate with the fixing belt and the fixing buckle and adjust it to a suitable tightness to ensure that the affected limb is fixed in a proper position.

[0007] The beneficial effects of the basic solution are as follows: 1. Using a splint as a fixing plate in the prior art may cause the affected limb to be compressed, thus causing symptoms such as pressure sores. However, in this solution, the airbag layer is provided on the inner wall of the fixing plate as a support, which can effectively prevent the affected limb from being overloaded, thereby relieving the pressure on the blood vessels inside the affected limb.

[0008] 2. There are dense ellipsoidal heat dissipation balls on the surface of the airbag layer. When the temperature of the affected limb is normal, the ellipsoidal heat dissipation balls can play a supporting role together with the airbag layer. When the temperature inside the fixing plate is too high, since the heat dissipation balls are made of heat-expandable materials, the ellipsoidal heat dissipation balls will expand and increase in size. Then, their shape will change from ellipsoidal to spherical, and the heat dissipation balls will bulge, and the gaps between them will become larger. As a result, the gap space on the surface of the skin of the affected limb can be increased, which can not only ventilate and dissipate heat, but also the bulging spherical shape can promote the blood flow in the blood vessels.

[0009] 3. By buckling the fixing belt and the fixing buckle, the fixing plate is moderately contracted to further ensure the stable fixation of the affected limb.

[0010] Furthermore, a number of ventilation holes are provided on the inner walls of the front fixing plate and the rear fixing plate, and a number of through grooves corresponding to the ventilation holes are provided on both the first airbag layer and the second airbag layer.

[0011] The beneficial effects of the basic solution are as follows: Because the traditional splint is relatively closed and covered, while the inner wall of this fixing plate is connected with a number of ventilation holes, it can play a role in ventilation and heat dissipation to a certain extent, and the depression effect generated by the ventilation holes on the airbag layer can also play a fitting effect on the affected limb.

[0012] Furthermore, slide rails are provided on both sides of the outer walls of the front fixing plate and the rear fixing plate. A number of circular fixing holes are opened on the slide rails, a slide bar is slidably connected inside the slide rails, and a number of circular fixing grooves corresponding to the circular fixing holes are provided on the slide bar.

[0013] The beneficial effects of the basic solution are as follows: Since there are differences in each patient's body, and the limb lengths vary from person to person, the positions of the fixing plates that need to be adjusted are also different. At this time, it is necessary to slidably connect the slide rails and the slide bars on both sides of the fixing plate. The slide bar can extend and contract along the direction of the fixing plate. When adjusted to a suitable position, it is fixed through the circular fixing grooves and the circular fixing holes, which is beneficial to adjusting to the optimal position.

[0014] Further, a circular coupling is rotatably connected to one end of the front fixing plate close to the rear fixing plate, and both ends of the circular coupling are rotatably connected to the sliding rods extended from the front fixing plate and the rear fixing plate respectively.

[0015] The beneficial effect of the basic solution is that since the positions of the affected limbs are different and the affected limbs are connected by joints and need to be rotated when necessary, this solution proposes to rotatably connect a circular coupling between the front fixing plate and the rear fixing plate. When the circular coupling connects the sliding rods extended from the two fixing plates, it can make the two sliding rods rotate to form an angle.

[0016] Further, a limiter is provided on the circular coupling.

[0017] The beneficial effect of the basic solution is that when the sliding rod rotates and is adjusted to an appropriate angle, it is fixed by the limiter on the circular coupling to ensure that the joint of the patient is fixed and bent to a suitable angle.

[0018] Further, both the front fixing plate and the rear fixing plate include a first plate, a second plate and a third plate. A plurality of sliders are rotatably connected to one side of the first plate and the third plate close to the second plate. A plurality of arc-shaped sliding rods corresponding to the sliders are rotatably connected to both sides of the second plate. A plurality of arc-shaped sliding rails are slidably connected to the arc-shaped sliding rods, and the sliders rotatably connected to the first plate and the third plate are slidably connected to the arc-shaped sliding rails.

[0019] The beneficial effect of the basic solution is that traditional external fixation braces mostly need to distinguish between arm braces and leg braces, while the brace in this solution can expand the arc-shaped fixed space of the sliding rail through the arc-shaped sliding rails in the fixing plate, which can provide certain convenience for patients. At the same time, as the space expands, it can further wrap the affected limb of the leg.

[0020] Further, symmetric detachable rotary fixing buckles are provided on both sides of the outer wall of the rear fixing plate, and both ends of a neck strap are fixedly connected to the two detachable rotary fixing buckles.

[0021] The beneficial effect of the basic solution is that when the affected limb is the arm, a neck strap is needed to provide a supporting force for the brace at this time. The fixing buckle and the neck strap can rotate, which is convenient for the patient to make appropriate adjustments. When the affected limb is the leg, the fixing buckle can be removed and the neck strap can be removed together to prevent affecting the external fixation of the leg.

[0022] Further, a neck protection air cushion layer is provided in the middle section of the neck strap.

[0023] The beneficial effect of the basic solution is that since the middle section of the neck strap fits the patient's posterior neck, the neck protection air cushion layer provided in the middle section of the neck strap in this solution can reduce the pressure on the patient's posterior neck.

[0027] The following is a further detailed description through specific implementation manners:

[0028] The reference numerals in the accompanying drawings of the specification include: front fixing plate 1, first airbag layer 2, ventilation holes 3, fixing belts 4, fixing buckles 5, ellipsoidal heat dissipation balls 6, slide rails 7, slide rods 8, limiters 9, circular couplings 10, neck straps 11, rear fixing plate 12, detachable rotary fixing buckles 13, arc-shaped slide rods 14, arc-shaped slide rails 15, circular fixing holes 16, second airbag layer 17, neck protection air cushion layer 18, circular fixing grooves 19, sliders 20, first plate 21, second plate 22, third plate 23.

[0029] Embodiment, basically as shown in the appendix Figures 1 - 3 Shown: A multifunctional external fixator for osteoporotic fractures includes a front fixing plate 1. A first airbag layer 2 is provided on the inner wall of the front fixing plate 1. The front fixing plate 1 is rotatably connected to a rear fixing plate 12. A plurality of fixing belts 4 are fixedly connected to one side of the outer walls of the front fixing plate 1 and the rear fixing plate 12. A second airbag layer 17 is provided on the inner wall of the rear fixing plate 12. A plurality of fixing buckles 5 are provided on the outer walls of the front fixing plate 1 and the rear fixing plate 12 on the side opposite to the fixing belts 4. When the fixing buckles 5 are connected to the fixing belts 4, it can effectively prevent the affected limb from shaking. A plurality of ellipsoidal heat dissipation balls 6 are provided on the surfaces of the first airbag layer 2 and the second airbag layer 17, which can play a supporting role together with the airbag layer, and adjacent heat dissipation balls 6 are fixedly connected by the long axis endpoints. The ellipsoidal heat dissipation balls 6 are made of heat-expandable materials and can expand when heated. The shape of the heat dissipation balls changes from ellipsoidal to spherical, increasing the clearance space at the contact part between the affected limb and the airbag layer, thus accelerating air flow to play a heat dissipation role. At the same time, the deformation of the ellipsoidal heat dissipation balls 6 can also play a certain massage role for the affected limb, promoting blood flow in the blood vessels inside the affected limb.

[0030] Both the inner walls of the front fixing plate 1 and the rear fixing plate 12 are connected with a number of ventilation holes 3. The first airbag layer 2 and the second airbag layer 17 are both provided with a number of through grooves corresponding to the ventilation holes 3. The ventilation holes 3 can increase the air circulation inside the fixing plate so as to achieve the heat dissipation effect. On both sides of the outer walls of the front fixing plate 1 and the rear fixing plate 12, slide rails 7 are fixedly connected. A number of circular fixing holes 16 are formed on the slide rails. A slide rod 8 is slidably connected inside the slide rail 7. A number of circular fixing grooves 19 corresponding to the circular fixing holes 16 are provided on the slide rod 8. And the slide rod 8 can slide along the slide rail 7 towards one end of the fixing plate. The slide rods 8 respectively extending from the front fixing plate 1 and the rear fixing plate 12 are both hinged with a circular coupling 10. A limiter 9 is provided on the circular coupling 10, which can help the patient adjust the angle between the joints, so as to reach a more suitable angle.

[0031] Both the front fixing plate 1 and the rear fixing plate 12 include a first plate 21, a second plate 22 and a third plate 23. A number of sliders 20 are hinged on one side of the first plate 21 and the third plate 23 close to the second plate 22. On both sides of the second plate 22 close to the first plate 21 and the third plate 23, a number of arc-shaped slide rods 14 corresponding to the sliders 20 are hinged. The arc-shaped slide rods 14 are slidably connected with an arc-shaped slide rail 15. The sliders 20 hinged on the first plate 21 and the third plate 23 are slidably connected with the arc-shaped slide rail 15. When the arc-shaped slide rail 15 slides, the wrapping area inside the fixing plate can be enlarged, so as to be used for fixing the leg. On both sides of the outer wall of the rear fixing plate 12, symmetrically rotatable fixing buckles 13 are provided. The rotatable fixing buckles 13 are fixedly connected with a neck guard belt 11. A neck guard air cushion layer 18 is provided in the middle section of the neck guard belt 11. The neck guard air cushion layer 18 can disperse the pressure of the neck belt 11 on the back of the neck, so as to reduce the pressure on the back of the neck.

[0032] The specific implementation process is as follows: First, place the affected limb horizontally into the front fixing plate 1 and the rear fixing plate 12, so that the skin of the affected limb is closely attached to the first airbag layer 2 and the second airbag layer 17. Then connect a number of fixing straps 4 on one side of the fixing plate with the corresponding fixing buckles 5 on the opposite side one by one, and adjust to the best tightness. When the fixing straps 4 are fixed, the slide rails 7 are respectively fixedly connected to both sides of the front fixing plate 1 and the rear fixing plate 12, and the slide rod 8 can slide relative to the slide rail 7. By adjusting the sliding length of the slide rod 8 and the angle of the circular coupling 10, the position of the affected limb can be adjusted to a suitable position. Then hang the middle section of the neck belt 11 provided with the neck guard air cushion layer 18 on the back of the neck, so as to achieve the effect of providing support force.

[0033] When the present utility model is applied to the affected limb of the leg, it is necessary to unfold the arc-shaped slide rails 14 embedded in the front fixing plate 1 and the rear fixing plate 12. When the arc-shaped slide rods 15 are pulled out from the arc-shaped slide rails 14, the wrapping area inside the fixing plate will increase, so as to meet the space required for fixing the leg. At the same time, it is necessary to disassemble the neck belt 11 by removing the detachable rotatable fixing buckles 13 to prevent the neck belt itself and entanglement with the affected limb from causing potential safety hazards.
