[0002] In emergency treatment of limb trauma, fractures and open injuries are often accompanied by complex conditions such as bleeding and tissue damage, which require timely and effective fixation and hemostasis. Otherwise, the injury will worsen and even endanger the patient's life. At the same time, during the emergency rescue and transfer process, in order to reduce the risk of secondary injury to the patient, a fast, stable and multifunctional fixation device is urgently needed to buy time for subsequent treatment.

[0003] At present, traditional first aid fixation devices still have the following problems:

[0004] (1) Existing limb trauma emergency fixation devices are difficult to achieve accurate and stable fixation in some special parts, such as near joints, hands and feet, and the fixation effect is poor;

[0005] (2) Existing emergency fixation devices for limb trauma use complex binding or connection methods, which are not only cumbersome to operate but also difficult to remove, increasing the removal time.

[0006] (3) Existing emergency fixation devices for limb trauma are difficult to detect bleeding at the trauma site in a timely manner due to bumps or other reasons during transportation.

[0007] Therefore, the present invention aims to provide a multifunctional limb trauma first aid fixation device for orthopedics to solve the above problems. Summary of the Invention

[0008] The purpose of the present invention is to provide a multifunctional limb trauma emergency fixation device for orthopedics. The present invention can fix the upper and lower ends of the limb fracture by arranging a fixing structure on the fixing plate. At the same time, a pressurized hemostatic structure is arranged between the fixing structures, which can simulate the first aid personnel to perform pressurized hemostasis on the limb trauma, so that during the process of transporting the patient for emergency first aid, the patient's wound can be continuously and stably pressurized and hemostatically treated, thereby improving the hemostatic effect on the limb trauma. In addition, the present invention also adopts an intelligent control system to automatically adjust the airbag inflation volume, which can further ensure the accuracy of the fixation and hemostasis effect.

[0009] The above technical objectives of the present invention are achieved through the following technical solutions: a multifunctional limb trauma emergency fixation device for orthopedics, comprising a fixing plate, two support rods are provided on the fixing plate, and both support rods are provided with a fixing structure, and the two fixing structures are respectively used to fix the upper and lower ends of the limb fracture, and a connecting rod is provided between the two support rods, and a rotating ring is provided on the connecting rod, and a pressurized hemostatic structure is provided on the rotating ring, and the pressurized hemostatic structure is used to pressurize and stop bleeding at the limb trauma.

[0010] By adopting the above-mentioned technical solution, the present invention can fix the upper and lower ends of the limb fracture by arranging a fixing structure on the fixing plate. At the same time, a pressurized hemostatic structure is arranged between the fixing structures, which can simulate the first aid personnel to perform pressurized hemostasis on the limb trauma. In the process of transporting the patient for emergency first aid, the pressurized hemostatic structure can continuously and stably perform pressurized hemostasis treatment on the patient's wound, thereby improving the hemostatic effect on the limb trauma and avoiding secondary damage to the patient due to the transportation process.

By inflating the fixing airbag, the upper and lower ends of the limb fracture can be stably and accurately fixed. The airbag is elastic and can adapt to the limbs of different patients, while reducing the pressure on the patient's limbs and improving comfort.

When the fastening bolt is tightened, the U-shaped splint and the fixing plate are relatively fixed, thereby fixing the patient's limbs. When the fastening bolt is loosened, the U-shaped splint and the fixing plate can be adjusted in relative angle. In the rescue situation where the patient's limbs cannot be straightened due to pain or severe trauma and can only be maintained at a certain angle, the angle of the U-shaped splint can be adjusted to the position of the limb trauma, thereby achieving the effect of precise fixation.

The detachable design of the hemostatic pack facilitates the replacement and replenishment of the hemostatic material, ensuring the continuity and reliability of the hemostatic effect.

[0033] 3. The present invention adopts a rotating collar and telescopic rod design, which enables the pressurized hemostatic structure to be flexibly adjusted according to the position and angle of the limb. At the same time, the cooperation between the telescopic rod and the annular groove ensures the stability and flexibility of the pressurized hemostatic structure during operation, adapting to the first aid needs of limb trauma at different locations and angles.

[0034] 4. The present invention realizes automatic control of the fixation airbag and the pressurization airbag through an intelligent control system. The data acquisition module, data analysis module and automatic control module work together to automatically adjust the airbag inflation volume according to the pressure data fed back by the sensor, ensuring the accuracy of fixation and hemostasis. The voice broadcast module can provide real-time feedback of key information to emergency personnel, guide emergency operations, reduce human errors, and improve rescue efficiency.

[0035] 5. Through multifunctional integrated design, the present invention reduces the dependence on traditional multiple single-function equipment during the first aid process, reduces the procurement and maintenance costs of medical equipment, and at the same time, the precise operation of the intelligent control module reduces unnecessary resource consumption during the first aid process and improves the utilization efficiency of medical resources.

[0055] Working principle: When using the limb trauma first aid device, the first aid personnel first observe the position and angle of the patient's limb trauma, and then rotate and adjust the angles of the two U-shaped splints 3 relative to the fixing plate 1 so that the angles of the two U-shaped splints 3 are consistent with the current bending angle of the patient's limb. The upper and lower ends of the patient's limb fracture are slightly placed in the two U-shaped splints 3 respectively. At this time, the fastening bolts are tightened to the right so that the fastening bolts are pressed against the support rod 2 to complete the fixation of the angle between the U-shaped splint 3 and the fixing plate 1. At this time, the fixing airbag 4 is inflated to complete the fixation of the upper and lower ends of the patient's fracture. By adjusting the telescopic rod 8, the pressurized hemostatic structure is located at the patient's limb trauma position, and the arc plate 10 is opened and sleeved on At the patient's limb trauma site, close the fixed buckle and slide the sliding block 9 along the annular groove 11 with damping, so that the pressurized hemostatic structure rotates, and then the position of the hemostatic pack 15 is adjusted so that the hemostatic pack 15 can be accurately located at the limb trauma site.

When it is necessary to unlock the limb trauma first aid device, open the fixed buckle 13 and deflate the airbag to quickly and conveniently complete the operation of unlocking the device.
