In this embodiment, both ends of the hollow tube 331 extend 3mm to 5mm beyond the outer side surface of the slide rail 34, so as to prevent the hollow tube 331 from tilting due to uneven pulling force of the first elastic element 31 and even from separating from the slide rail 34, and the size of the hollow tube 331 extending beyond the slide rail 34 can be selected by those skilled in the art according to actual situations. The two ends of the hollow tube 331 are provided with the blocking pieces, so that the clamping mechanism 33 can smoothly slide along the slide rail 34 and is not easy to separate from the slide rail 34, and the smooth and stable sliding is guaranteed. The stopper is provided with an opening, and the hollow tube 331 can be extended from the opening of the stopper by the chuck 333. Preferably, the second elastic member 332 is a compression spring, and the compression spring can provide a stable elastic force to push one end of the chuck 333 away from the second elastic member 332 out of the hollow tube 331, so as to ensure that the chuck 333 can be stably clamped in the first clamping portion 321.
In this embodiment, the first engaging portion 321 is made of plastic, so that the first engaging portion 321 can elastically deform, and when the external force is applied, the first engaging portion 321 can deform to press the chuck 333, so that the first engaging portion 321 returns to its original state after the external force is removed. Specifically, the first clip portion 321 includes a pressing head 3211 and a clip 3212, a slot is provided on the clip 3212, and one end of the clip 333, which is away from the second elastic member 332, can be clipped in the slot of the clip 3212. Since the first clip portion 321 is made of plastic, the pressing head 3211 and the clip 3212 can be elastically deformed relatively, so that the pressing chuck 333 can be pressed by a subsequent external force.
Further, one side of the clip 3212 in the housing 32 is provided with a guide slope for enabling the chuck 333 to smoothly slide along the guide slope under the guiding action of the guide slope. When the first binding band 2 is pulled to drive the clamping mechanism 33 to slide along the sliding rail 34, the first elastic element 31 extends, the clamping head 333 slides along the guide inclined plane of the clamping element 3212, and meanwhile, the second elastic element 332 is continuously compressed; when the chuck 333 is separated from the guiding slope, the second elastic member 332 pushes out the chuck 333 to extend, the chuck 333 is clamped in the clamping groove of the clamping member 3212, and at this time, the first binding band 2 stops being pulled, and the clamping mechanism 33 has a tendency to slide along the sliding rail 34 in the direction in which the first elastic member 31 contracts under the action of the contraction force of the first elastic member 31, so that the chuck 333 can be firmly clamped on the clamping member 3212. More preferably, one end of the chuck 333 away from the second elastic member 332 is provided with an inclined surface, and the inclined surface is parallel to the guiding inclined surface of the clamping member 3212, so that the chuck 333 can slide smoothly along the clamping member 3212.
In this embodiment, when the chuck 333 is engaged with the engaging member 3212, the pressing head 3211 is aligned with the chuck 333. Preferably, one end of the pressing head 3211 near the chuck 333 is formed as an inclined surface parallel to the inclined surface of the chuck 333 so that the contact surface between the pressing head 3211 and the chuck 33 is uniformly applied with force when the pressing head 3211 presses the chuck 333. Because the pressing head 3211 and the clamping head 333 are arranged in an aligned manner, when the pressing head 3211 is pressed in the direction of the second elastic member 332, the pressing head 3211 presses the clamping head 333, the clamping head 333 inwardly compresses the second elastic member 332 to contract until the clamping head 333 is separated from the clamping connection with the first clamping connection portion 321, so that the clamping mechanism 33 drives the first bandage 2 to contract under the contraction force of the first elastic member 31, the pelvis belt body 1 contracts, and the wound part is pressed and fixed.
As shown in fig. 3, in the present embodiment, the second strap 4 is provided with a plurality of slots 41 at intervals along the length direction thereof, and the size of the slots 41 is configured to enable the buckle 5 to be snapped into the slots 41. Preferably, the buckle 5 in this embodiment is an automatic buckle in an automatic buckle belt, and is a connecting member commonly used in the art, and the working principle and method thereof are not described herein again.
In the use process, the buckle 5 is clamped in the clamping grooves 41 at different positions, so that the purpose of adjusting the length of the second binding band 4 is achieved, the overall size of the pelvic girdle is further adjusted, and the purpose of adjusting the pressing and fixing acting force of the pelvic girdle on the wound part is achieved. Preferably, the plurality of catching grooves 41 of the second strap 4 are uniformly spaced at regular intervals, so that the length of the second strap 4 can be uniformly adjusted when the length of the second strap 4 is adjusted.
The following describes the operation of the embodiment of the present invention.
Before the pelvis strap is bound on the wound of the patient, the first binding belt 2 is pulled to enable the clamping mechanism 33 in the pressing and contracting device 3 to be clamped on the first clamping portion 321, then the pelvis strap body 1 is wrapped on the wound of the patient, the second binding belt 4 is wound and penetrates through the back buckling ring 6 to be clamped in the automatic buckle 5, and the binding on the wound of the patient is completed. Then, the pressing head 3211 on the compression device 3 is pressed to separate the clamping mechanism 33 from the first clamping portion 321, and the first elastic member 31 contracts and drives the first bandage 2 to contract, so as to pull the second bandage 4 to contract, and further drive the pelvic girdle body 1 of the pelvic girdle to contract, thereby stably pressing and fixing the wound. With the above configuration, the pressing force and the fixing force of the pelvic girdle on the wound part can be kept continuous, and the pressing force and the fixing force can be continuously provided even if the pelvic girdle is slightly displaced and loosened. The pelvic girdle can effectively avoid fracture displacement, maintain the stability of pelvic rings, increase pelvic pressure, reduce visceral blood loss and reduce the harm caused by pelvic trauma.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
