The arm guard 2 serves as a base layer. The arm guard 2 is the part that directly contacts the skin. It uses a quick-drying fabric with high elasticity. This material not only provides a good fit, but also has excellent breathability, which can effectively keep the skin dry and reduce eczema or sweat irritation caused by long-term wear. The built-in air bag dressing can be inflated or deflated as needed to adapt to changes in limb swelling, disperse pressure, and reduce the risk of pressure sores. In addition, the design of the arm guard 2 fully considers the needs of patients at different stages, which can not only provide necessary support for the injured part in the early stage, but also allow a certain degree of activity in the later stage to promote blood circulation.
[0044] The upper arm protective gear assembly is arranged on the outer side of the arm guard 2 corresponding to the upper arm; the upper arm protective gear assembly comprises:
[0045] An upper arm external fixation brace 1, having a heating and shaping function to fit the shape of the patient's upper arm;
[0046] The upper Velcro strap 3 is used to adjust the tightness of the upper arm external fixation brace 1 .
[0047] The upper arm external fixator 1 is made of thermoplastic material with memory function. After heating, it can be adjusted according to the shape of the patient's upper arm, and after cooling, it will firmly maintain this shape, thereby achieving a highly personalized fit. The upper Velcro strap 3 is made of high-strength Velcro material, which not only ensures the stability of the fixation, but also facilitates the adjustment of tightness at any time according to actual conditions.
[0048] The forearm protective gear assembly is arranged on the outer side of the arm guard 2 corresponding to the forearm; the forearm protective gear assembly comprises:
[0049] The forearm external fixation brace 10 has a heat shaping function to fit the shape of the patient's forearm;
[0050] A front Velcro strap 9, wherein the front Velcro strap 9 is used to adjust the tightness of the forearm external fixation brace 10;
[0051] The splint unit is arranged between the arm guard 2 and the forearm external fixation brace 10 .
[0052] The forearm external fixation brace 10 also uses a thermoplastic breathable material as the forearm external fixation brace 10, and is specially equipped with a splint unit, which includes: a wooden neutral plate 7 and a forearm radial splint 13, a forearm ulnar splint 14, a forearm dorsal splint 12 and a forearm palmar splint 11. The forearm radial splint 13, the forearm ulnar splint 14, the forearm dorsal splint 12 and the forearm palmar splint 11 are respectively arranged on the upper, lower, left and right sides of the arm guard 2, and are fixed by the forearm external fixation brace 10 and the front Velcro strap 9. The neutral plate 7 is bonded to the forearm external fixation brace 10 by Velcro and fixed by the front Velcro strap 9; the neutral plate 7 is provided with a column for palm grip. These splints are arranged around the forearm to provide all-round support for the fracture from different angles.
[0053] The front Velcro strap 9 arranged on the outside of the forearm external fixation brace 10 is made of high-strength Velcro material, which not only ensures the stability of the fixation, but also facilitates the adjustment of tightness at any time according to actual conditions. The neutral plate-forearm external fixation arm guard connecting belt 15 is located between the forearm external fixation brace 10 and the neutral plate 7, and is also made of Velcro material, which is convenient for adjusting the position according to the length of the patient's forearm, ensuring that the wrist is in a neutral position, and preventing further injuries caused by incorrect posture.
[0054] A connecting unit, wherein the connecting unit is used to connect the upper arm guard assembly and the forearm guard assembly to achieve fixation or rotation of the upper arm guard assembly and the forearm guard assembly.
[0055] The connecting unit comprises:
[0056] An upper connecting rod 5, wherein the upper connecting rod 5 is fixed on the upper arm external fixing protector 1;
[0057] A front connecting rod 6, wherein the front connecting rod 6 is fixed to a forearm external fixing device 10;
[0058] A nut 4, wherein the nut 4 is used to configure the upper connecting rod 5 and the front connecting rod 6 to be rotatably connected;
[0059] The screw 8 is detachable and passes through the upper connecting rod 5 and the front connecting rod 6 in sequence.
[0060] The front connecting rod 6 is a key component connecting the upper arm external fixation brace 1 and the forearm external fixation brace 10, and is fixed by a punching design, screws 8, and nuts 4. At the same time, this design allows the neutral plate 7 to be removed after the fracture is stabilized, so as to start functional exercises of the wrist joint and avoid joint stiffness caused by long-term fixation. The various splints of the forearm not only enhance the fixation effect, but also the selection of its wood material takes into account both lightness and firmness, and can provide sufficient protection for the fracture site without affecting daily life.
[0061] The upper connecting rod 5 is a key component connecting the upper arm external fixation brace 1 and the forearm external fixation brace 10. Through the punching design and the screws 8 and nuts 4, the elbow joint can be completely fixed in the early stage. In the recovery stage, the range of motion can be gradually increased by removing the connecting rod fixing screws 8, helping the patient to gradually restore the function of the elbow. In practical applications, the working principle of the non-surgical treatment external fixation device for upper limb fractures of this application is as follows:
[0062] 1. Initial assessment and preparation: The doctor will first conduct a comprehensive assessment of the patient's fracture to determine the most appropriate treatment method. For cases suitable for non-surgical treatment, manual reduction will be performed to return the fracture ends to their normal anatomical position as accurately as possible. At this stage, the medical staff will also explain the entire treatment process to the patient to enhance the patient's understanding and willingness to cooperate.
[0063] 2. Device installation: After the reduction is completed, the non-surgical external fixation device for upper limb fractures of this application is immediately applied. The staff will adjust the position of each component according to the patient's limb size, use thermoplastic materials to shape the shape that conforms to the curve of the patient's arm, and secure it with straps. At this time, the upper connecting rod and the front connecting rod are completely locked to ensure that the elbow joint is in a fixed state and minimize any movement that may interfere with fracture healing. In addition, during installation, attention will be paid to checking whether the device is suitable to ensure that there is no place that is too tight or too loose, so as not to cause discomfort or affect the fixation effect.
[0064] 3. Monitoring and adjustment: Over time, medical staff need to regularly check the status of the device and the patient's response, and adjust the tightness of the straps if necessary to adapt to changes in limb swelling. If pressure sores or other signs of adverse reactions are found, timely measures should be taken, such as readjusting the device or changing the dressing. In some cases, the device may also need to be reshaped to ensure that it always provides the best support.
[0065] 4. Transition to the rehabilitation stage: When the fracture reaches a certain degree of stability, it enters the rehabilitation stage. At this time, the range of motion of the elbow joint can be increased by gradually loosening the screws connecting the two connecting rods, and the patient is encouraged to perform appropriate functional exercises, such as flexion and extension exercises. For the wrist joint, the neutral plate can also be removed at an appropriate time to guide the patient to start gentle wrist movements and gradually restore hand function. During this period, medical staff will closely monitor the patient's progress to ensure that each increase in activity is safe and controllable, and adjust the rehabilitation plan according to actual conditions.
[0066] 5. Post-care and removal: Finally, after the fracture is completely healed and confirmed by the doctor, the fixation device can be safely removed. Throughout the treatment process, individualized management and gradual progress are always emphasized to ensure that every patient can get the best rehabilitation experience. After the device is removed, the medical staff will also guide the patient on how to continue appropriate rehabilitation training to consolidate the treatment results and restore normal quality of life.
[0067] The above description is only a preferred embodiment of the present invention and is used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
