Description

Technical Field

[0001] The invention belongs to the technical field of limb fixation equipment, and in particular relates to a limb fixation device for emergency patients. Background Art

[0002] In emergency medicine, limb injuries (including fractures, dislocations, severe soft tissue injuries, and vascular and neurological injuries) are among the most common emergencies. These injuries often result from traffic accidents, falls from heights, sports incidents, violent conflicts, or everyday mishaps. Patients often present to the emergency department with severe pain, significant deformity, swelling, functional impairment, and even open wounds. Timely and effective immobilization of the limb is a critical first step in emergency treatment.

[0003] The existing application number is: CN202411936283.0, and the invention name is: An application document for a limb fixation device for emergency patients. After the limb is fixed, the limiting link is removed from the slot, and the rotation effect of the joint link is used to achieve a certain degree of movement at the limb joint. At the same time, by adjusting the support height of the hinge plate on the rear fixing plate, the patient can swing the movable joint upward and left and right while also swinging the movable joint downward. However, the above application document, combined with the drawings of the submitted specification, requires the patient's limb to be lifted and placed in the device before use. If the injured person's limb is inconvenient and cannot move, the above application device will cause secondary damage to the body. Summary of the Invention

[0004] In view of the above situation, in order to avoid moving the limb while fixing the limb and causing damage to the limb, the present invention provides a limb fixation device for emergency patients, which uses a combined assembly method to limit the range of limb movement, and automatically adjusts the distance between the fixation device and the limb through a unilateral pressing fixation method to achieve the effect of automatic limb fixation.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a limb fixation device for emergency patients, including a strap and a fixing plate. The fixing plates are provided in two groups, and a limb limiting plate is provided between the two groups of fixing plates.

The transmission adjustment device is connected to the fixing plate, and the fixing plate is provided with a sliding limiting device.

[0006] Furthermore, the bottom wall of the limb limiting plate is set to be arc-shaped, the top wall of the limb limiting plate is provided with a handle, and the upper wall of the limb limiting plate is provided with an operating box for installing a transmission adjustment device.

[0007] Furthermore, the pressing and limiting plate is configured as an arc-shaped structure, and the pressing and limiting plate is in contact with and connected to the bottom wall of the limb limiting plate.

[0008] Furthermore, the transmission adjustment device includes a lifting rack, gear one, gear two, a bevel gear group, gear three and a transverse rack. The lifting rack is fixedly mounted on the top wall of the pressing limit plate, and the lifting rack is engaged and slid in the vertical direction on the limb limit plate. The gear one, gear two and bevel gear group are all engaged and mounted in the operating box. The lifting rack is meshed with gear one, and the gear one is meshed with gear two. The bevel gear group is connected to gear two through a bracket, and the gear three is connected to the bevel gear group through a bracket. The transverse rack is meshed with gear three for transmission connection.

[0009] Furthermore, the transverse rack is engaged and slid on the running box, and the transverse rack is hinged to the fixed plate.

[0010] Furthermore, the lifting rack is provided with a limiting toothed protrusion, the operating box is provided with a toothed plate for limiting the range of movement of the toothed protrusion, the toothed plate is provided with a group of connecting plates, and a spring is provided between the connecting plate and the outer wall of the operating box.

[0011] Furthermore, the fixing plate includes a leg fixing plate 1, a leg fixing plate 2 and an external limiting plate, the external limiting plate is hinged to the transverse rack, the leg fixing plate 1 is snap-fitted and installed on the side wall of the external limiting plate, and the leg fixing plate 2 is arranged below the leg fixing plate 1.

[0012] Furthermore, the strap is engaged and slid in the first leg fixing plate, and the second leg fixing plate is fixedly mounted on the strap. The distance between the first leg fixing plate and the second leg fixing plate can be changed by pulling the strap.

[0013] Furthermore, the sliding limit device includes a pin and a ratchet, the ratchet is arranged on the strap, the external limit plate is provided with an adjustment slot, the adjustment slot is provided with a sliding card plate, the card plate is provided with a pin, the ratchet is engaged with the pin, the pin is used to limit the pulling length of the strap, and the card plate is connected to the limb limit plate by a spring.

[0014] Furthermore, a rotation limiting slot is provided on the outer wall of the limb limiting slot, and a small rotating block is provided on the center of the rotation limiting slot. When the small block rotates, it limits the card plate when the card plate is pulled outward, ensuring that the strap is not blocked when being pulled.

[0015] Furthermore, a lock buckle is provided on the external limiting plate. When the strap is used for binding, the strap is passed from the top of the limb limiting plate to the bottom of the limb, and finally wrapped around the lock buckle on the side of the strap to fix the limb.

[0016] Furthermore, a spring is provided between the bottom wall of the limb limiting plate and the top wall of the pressing limiting plate.

[0017] Preferably, the transverse rack is fixedly connected to the external limiting plate.

[0018] This solution provides a limb fixation device for emergency patients, which has the following beneficial effects: (1) By pressing the limit plate into contact with the limb, the two sets of fixed plates are moved horizontally through the transmission action of the gear and rack, so that the fixed plates clamp the limb. When the lifting rack moves, the toothed protrusions on the back of the rack contact and collide with the toothed plate, and under the limiting action of the toothed plate, the position of the lifting rack is relatively fixed, ensuring that the fixed plates are close to the limb without causing reverse displacement. (2) When the strap is moved within the leg fixing plate 1 under the limitation of the latch and the ratchet, the moving distance of the strap can be limited, so that the distance between the leg fixing plate 1 and the leg fixing plate 2 remains fixed, which is beneficial for the subsequent leg binding and the leg fixing operation plan.
