Technical Field

[0001] This invention relates to the field of orthopedic nursing technology, specifically to an emergency fixation device for trauma orthopedic nursing. Background Technology

[0002] Traumatic fractures are caused by external force directly impacting the bone, resulting in a disruption of the integrity and continuity of the bone structure. These fractures are usually accompanied by significant pain, swelling, deformity, and functional impairment, and are one of the most common orthopedic emergencies.

[0003] In the clinical treatment of traumatic fractures, the routine procedure includes applying medication to the fracture site and then immobilizing it. However, existing fixation devices generally suffer from insufficient air permeability or rely mainly on passive ventilation mechanisms. In specific clinical situations, such passive ventilation methods often have low ventilation efficiency for the local microenvironment of the immobilized area. Summary of the Invention

[0031] The fixed support mechanism further includes a wrapping sleeve 402 and a double-through insert bag 403. The wrapping sleeve 402 is movably sleeved on the surface of the elastic encapsulation sleeve 102 to support the support insert 401. The double-through insert bag 403 is fixedly sewn to the outer surface of the wrapping sleeve 402. There are multiple double-through insert bags 403, which are evenly distributed and parallel to each other.

There are multiple female hook and loop fasteners 404, which are evenly distributed and parallel to each other. The female hook and loop fasteners 404 and the male hook and loop fastener 105 assist in the outward flipping and locking of the side sleeve 103 and the wrapping sleeve 402 for fixation.

With the support insert 401, wrapping sleeve 402, double-through insert bag 403, female hook and loop fastener 404 and through hole 405 in the insert, a rigid support can be formed by the support insert 401 during use to prevent bending of the affected area.

[0033] Working principle: In use, after applying medication to the patient's fracture site, the elastic liner 101 is placed over the bandage surface at the medication application site, ensuring the medication application site is in the center of the elastic liner 101. Then, the wrapping sleeve 402 is placed over the elastic wrapping sleeve 102. Next, support strips 401 are inserted one by one into the double-through insert bag 403. Finally, the flip-locking and tightening sleeve 103, located away from the extended spiral air duct 303, is flipped outwards, so that the flip-locking and tightening sleeve 103 wraps around the elastic liner 101 and the end of the wrapping sleeve 402. This is then completed through the public... The Velcro strip 105 and the female Velcro strip 404 are attached to fix the outwardly folded-over locking sleeve 103 to the surface of the wrapping sleeve 402. At this time, the locking sleeve 103 also wraps and limits one end of the support insert 401. Then, the extended spiral air guide pipe 303 is pulled out and connected to the detachable air pump 301 through the extended connector 304. The electromagnetic distribution valve 302 is opened, and the electromagnetic distribution valve 302 connects the extended spiral air guide pipe 303 to the first air inlet distribution pipe 206. The detachable air pump 301 is started. Pump 301 pumps air into the spiral fixing hose 202 through the extended spiral air guide manifold 303 and the first air inlet distribution pipe 206, causing the spiral fixing hose 202 to expand. Due to the limiting effect of the female Velcro strip 404 on the outside of the spiral fixing hose 202, the spiral fixing hose 202 expands inward. The inward expansion of the spiral fixing hose 202 compresses and shrinks the inner diameter of the elastic liner 101, so that the elastic liner 101 tightly wraps the bandage at the medication application position on the affected area. Then, the electromagnetic distribution valve 302 is closed to allow the spiral fixing hose to expand. The gas inside the hose 202 is maintained. Then, the detachable air pump 301 at the end of the extended connector 304 is removed. The extended spiral air guide tube 303 is spirally wound onto the surface of the flip-lock tension sleeve 103. The flip-lock tension sleeve 103 is also turned outward to wrap and store the extended spiral air guide tube 303. The flip-lock tension sleeve 103 is fixed to the wrapping sleeve 402 using the male Velcro strip 105 and the female Velcro strip 404, thereby limiting the other end of the support insert 401, thus completing the installation of the device. When active ventilation is required, the flip-locking sleeve 103 at one end of the extended spiral air guide tube 303 is flipped inward and unfolded. After the extended spiral air guide tube 303 is unfolded and extended, the flip-locking sleeve 103 is flipped inward and reset. Then, it is connected to the detachable air pump 301 through the extended connector 304. The electromagnetic distribution valve 302 is activated, which connects the extended spiral air guide tube 303 to the second air inlet distribution pipe 207. Then, the detachable air pump 301 is activated. The detachable air pump 301 guides the airflow into the spiral air guide tube 201 through the extended connector 304 and the second air inlet distribution pipe 207. Then, the airflow is ejected through the spiral exhaust gap 203 inside the spiral air guide tube 201. The ejected airflow passes through the elastic liner 101 and enters its interior. Then, it is discharged to both ends along the exhaust channel between the buffer breathable guide strips 104. When discharged, the airflow will carry away the heat of the bandage, so that the affected area is actively cooled.

7. The emergency immobilization device for trauma orthopedic nursing according to claim 2, characterized in that, The active air pumping mechanism also includes: An electromagnetic distribution valve (302) is fixedly installed on the surface of the elastic liner (101), and the output end of the electromagnetic distribution valve (302) is fixedly connected to one end of the first air intake distribution pipe (206) and one end of the second air intake distribution pipe (207), so as to control the conduction of the first air intake distribution pipe (206) and the second air intake distribution pipe (207) through the electromagnetic distribution valve (302).

8. The emergency immobilization device for trauma orthopedic nursing according to claim 7, characterized in that, The active air pumping mechanism also includes: An extended spiral air guide tube (303) is fixedly connected to the input end of the electromagnetic distribution valve (302), and the extended spiral air guide tube (303) is movably wound around the surface of the flip-lock tension side cylinder (103) so that the extended spiral air guide tube (303) can be extended outward. An extended connector (304) is fixedly connected to the input end of the extended spiral air guide pipe (303), and the extended spiral air guide pipe (303) is connected to the detachable air pump (301) through the extended connector (304). The detachable air pump (301), the extended spiral air guide pipe (303) and the extended connector (304) form a detachable structure to facilitate the removal of the detachable air pump (301).

9. The emergency immobilization device for trauma orthopedic nursing according to claim 2, characterized in that, The fixed support mechanism also includes: A wrapping sleeve (402) is movably fitted onto the surface of the elastic encapsulation sleeve (102) to support the support insert (401). A double-through insert bag (403) is fixedly sewn onto the outer surface of the wrapping sleeve (402), and there are multiple double-through insert bags (403), which are evenly distributed and parallel to each other. The support insert (401) is movably inserted into the inside of the double-through insert bag (403) to limit the support insert (401) through the double-through insert bag (403).
