Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment and relates to a splint fixing device for orthopedic emergency. Background Art

[0002] Orthopedic emergency is an important part of the hospital emergency department, mainly responsible for dealing with acute injuries to bones and joints caused by trauma, accidents, etc., such as fractures, joint dislocations, soft tissue injuries, etc. These injuries are usually sudden, urgent and critical, and require rapid assessment, diagnosis and treatment to relieve the patient's pain, prevent further injury, and restore the patient's limb function as much as possible. Orthopedic splints are often used in treatment. Orthopedic splints can be divided into many types, such as upper limb splints, lower limb splints, spinal splints, etc. The splints are tightly fixed on the fracture site, applying a certain amount of pressure to the fracture ends, maintaining the stability of the fracture ends, preventing fracture displacement, and providing favorable conditions for fracture healing.

[0003] Currently, when a patient's elbow joint is fractured, a splint is often used to fix the forearm, upper arm and elbow joint of the affected limb at the same time, fix the elbow joint at an appropriate angle, and then use a bandage or other fixation materials to tightly fix the splint and the affected limb together to maintain the stability of the fracture site.

[0004] However, due to factors such as local bleeding and tissue edema, the affected limb often continues to swell in different positions within 3-4 days after fixation, and the degree of swelling also varies. From the 4th to 5th day, the swelling gradually decreases and disappears. The splint is tightly fixed to the affected limb, so that the splint cannot adjust its tightness as the swelling in different positions of the affected limb increases or decreases, resulting in blood circulation disorders in the affected limb, displacement of fracture ends, etc., which aggravates the patient's pain and affects the normal healing of the fracture.

Each first connecting tube 3 A bellows 31 is arranged between 7 and the third connecting tube 39, and the two ends of the bellows 31 are respectively connected to the first connecting tube 37 and the third connecting tube 39. The bellows 31 is arranged between the corresponding arc-shaped clamping plate 1 and the mounting plate 10. The bellows 31 facilitates the arc-shaped clamping plate 1 to rotate around the mounting plate 10 without affecting the connection between the first connecting tube 37 and the third connecting tube 39. A shielding cloth 9 is arranged between the outer edge of each arc-shaped clamping plate 1 and the mounting plate 10, and the two ends of the shielding cloth 9 are respectively connected to the arc-shaped clamping plate 1 and the mounting plate 10, so as to facilitate shielding the bellows inside.

[0054] like Figure 2 , Figure 3 , Figure 8 As shown, each connecting strip 401 is evenly provided with a plurality of rubber protrusions 36 along its length direction on the side away from the corresponding arc splint 1. The end of each rubber protrusion 36 away from the connecting strip 401 is hemispherical. On the one hand, it is convenient to increase the friction between the connecting strip 401 and the affected limb, so that the patient is fixed more firmly and the fracture ends are avoided from being displaced. On the other hand, after the fracture ends are stabilized, the reciprocating movement of the two relatively arranged connecting strips 401 is adjusted to drive the plurality of rubber protrusions 36 thereon to slightly press the local position of the affected limb, thereby promoting the blood circulation of the affected limb and promoting the recovery of the affected limb.

[0055] like Figure 8 As shown, the opposite surfaces of the two auxiliary plates 3 are detachably provided with cotton pads, and the friction of the two auxiliary plates 3 on the elbow joint is increased by two rubber layers, so that the elbow joint is fixed more firmly and the patient can be more comfortable. The opposite surfaces of the two opposite clamping strips 4 are detachably provided with cotton pads, so that the patient can be more comfortable when clamping the patient's upper arm and forearm.

[0056] like Figure 1 As shown, each first connecting plate 5 and each second connecting plate 6 are telescopic structures, and a second positioning component is provided on each first connecting plate 5, by which the first connecting plate 5 is fixed after being extended and retracted, and a third positioning component is provided on each second connecting plate 6, by which the second connecting plate 6 is fixed after being extended and retracted. The extension and retraction of the two first connecting plates 5 facilitates the adjustment of the position of the corresponding two arc-shaped splints 1 for clamping the upper arm, and the extension and retraction of the two second connecting plates 6 facilitates the adjustment of the position of the corresponding two arc-shaped splints 1 for clamping the forearm, thereby adapting to patients of different heights. At the same time, adjusting the position of the two arc-shaped splints 1 for clamping the upper arm can adapt to fractures at different positions of the upper arm, and the position of the two arc-shaped splints 1 for clamping the forearm can adapt to fractures at different positions of the forearm, thereby improving the scope of application and improving practicality.

[0057] like Figure 1 As shown, a sling 45 is provided on the outer side of the two arc-shaped splints 1 that clamp the patient's forearm, and the two ends of the sling 45 are respectively connected to the outer side of the two arc-shaped splints 1, so that the sling 45 can be hung on the patient's neck and the patient's forearm can be hung in front of the chest when in use, thereby reducing the pressure on the elbow joint caused by the weight of the arm.

[0058] like Figure 1 As shown, a support plate 46 is provided on the two arc-shaped splints 1 that clamp the patient's forearm, and the support plate 46 is close to the ends of the two arc-shaped splints 1 away from the two second connecting plates 6. The support plate 46 and the ends of the two arc-shaped splints 1 are connected near the lower part by two fixing rods 47, and the two ends of each fixing rod 47 are detachably connected to the support plate 46 and the arc-shaped splint 1, respectively, so that when the patient's elbow joint and wrist joint are fractured at the same time and need to be fixed, the patient's wrist joint can be supported by the support plate 46. At the same time, the two ends of each fixing rod 47 can be adjusted to the installation position of the support plate 46 and the arc-shaped splint 1 to adapt to the distance adjustment between the two arc-shaped splints 1. When the wrist joint does not need to be fixed, the support plate 46 and the two fixing rods 47 can be removed from the two arc-shaped splints 1.

[0059] Working principle: When in use, the two arc splints 1 connected to the two first connecting plates 201 are clamped on the patient's upper arm so that the ten clamping strips 4 in the two arc splints 1 are in contact with the upper arm, and then the two arc splints 1 are fixed by the corresponding first straps 7, and then the remaining two arc splints 1 are rotated to adapt to the bending angle of the patient's forearm, and the two first connecting plates 201 and the two second connecting plates 202 are fixed by the first positioning assembly, and then the remaining two arc splints 1 are clamped on the forearm so that the ten clamping strips 4 in the remaining two arc splints 1 are in contact with the forearm, and then the remaining two arc splints 1 are fixed by the corresponding first straps 7, and then the two clamping plates 8 are fixed with the second straps 8, so that the elbow joint is clamped between the two auxiliary plates 3 to complete the clamping of the affected limb.

[0060] Then adjust the upper arm, forearm and elbow joint to make the support more secure. First, adjust the multiple adjustment blocks 28 on the mounting plate 10 corresponding to the upper arm from top to bottom, and turn the adjustment block 28. The adjustment block 28 drives the connecting rod 33 to slide in the second adjustment groove 30 into the first adjustment groove 29. The connecting rod 33 drives the slider 27 to slide in the slide groove 26, and then continue to turn the adjustment block 28 to drive the connecting rod 33 to slide in the first adjustment groove 29. The connecting rod 33 drives the rack 22 to move along the length direction of the mounting plate 10 through the slider 27, driving the gear 21 to rotate, the gear 21 drives the rotating shaft 18 to rotate, the rotating shaft 18 drives the elliptical wheel 19 to rotate, and the elliptical wheel 19 drives the two second plunger cylinders 13 to contract, and under the action of the two first elastic members 15, the two second plunger cylinders 13 are driven to extend, and the internal pressure increases, and the hydraulic oil is transmitted to the two first connecting pipes 37 through the two third connecting pipes 39, and then the pressure is transmitted through the two first connecting pipes 37 The ten first plunger cylinders 12 drive the ten connecting strips 401 to move toward each other, fix the position of the upper arm near the upper part, and slide the adjusting block 28 into the corresponding second adjusting groove 30 to fix the rack 22, and then push each adjusting block 28 downward in turn to adjust the tightness of different positions of the upper arm to fix the entire upper arm. At the same time, the different pushing distances of each adjusting block 28 are used to adapt to the swelling degree of the corresponding position, and then the multiple adjusting blocks 28 on the mounting plate 10 corresponding to the fixed forearm are pushed in turn from the direction toward the elbow joint to adjust the tightness of the forearm and completely fix the forearm. When fixing the forearm, when adjusting each adjusting block 28, part of the pressure of the corresponding two first connecting pipes 37 will be transmitted to the two first flow storage chambers 40 through the two second flow storage chambers 41, and then enter the corresponding multiple third plunger cylinders 14, drive the multiple third plunger cylinders 14 to extend, drive the two auxiliary plates 3 to move toward each other, adjust the tightness of the elbow joint, and fix the elbow joint at the same time.

[0061] As time goes by, the degree of swelling in different parts of the patient first gradually increases, then gradually decreases and disappears after reaching the maximum. According to the location of the swelling and the increase, the adjustment block 28 corresponding to the swelling location is first adjusted, and the spacing between the corresponding ten connecting strips 401 is adjusted so that the spacing first increases and then decreases to adapt to the increase or decrease of the swelling.

[0062] After the fracture ends are stabilized, one of the adjustment blocks 28 on the mounting plate 10 corresponding to the fixed upper arm is moved, which drives the corresponding ten second plunger cylinders 13 to continuously extend and retract, and drives the ten connecting strips 401 to move back and forth. Each connecting strip 401 drives the multiple rubber protrusions 36 thereon to lightly press the local position of the upper arm, thereby promoting the blood circulation of the patient's upper arm. When entering the late recovery stage, one of the adjustment blocks 28 on the mounting plate 10 corresponding to the fixed forearm can also be moved to lightly press the local position of the forearm, and at the same time, the elbow joint can be lightly pressed through the two auxiliary plates to promote the patient's blood circulation.
