Description

Technical Field

[0001] The utility model relates to the technical field of pelvic fixation, in particular to a pelvic fixation belt. Background Art

[0002] The pelvis is a basin-shaped bony structure connecting the spine and lower limbs. It is a complete bone ring formed by the sacrum and coccyx (the two lowest bones of the spine) at the back and the left and right hip bones. Since the pelvis is an important structure of the human body, it supports the upper body and connects the lower limbs. The pelvis is essential for human movement and balance. However, in certain circumstances, such as car accidents, explosions, building collapses and other accidents, the structural integrity of the human pelvic ring is severely damaged, which can cause massive bleeding, shock and organ damage. It cannot be carried directly, and the pelvis needs to be fixed with a pre-hospital emergency fixation device to limit massive bleeding from pelvic fractures and prevent secondary damage to the pelvis during transportation.

[0003] The existing pelvic fixation belt, as shown in CN218636170U, is fixed by connecting a belt to the human body into a ring. However, after connecting into a ring in this way, adjusting the tightness requires repeatedly pulling it off and re-bonding it into a ring, that is, the existing method is difficult to adjust the tightness.

[0023] Please also read Figure 1-Figure 3 , this embodiment provides a pelvic fixing belt, including a fixing belt body 1, a transmission mechanism 2 and a connecting rope 3;

[0024] The fixing belt body 1 is provided with two, and the transmission mechanism 2 and the fixing belt body 1 correspond one to one; the transmission mechanism 2 includes a driving wheel 21 and a driven wheel group 22, the driving wheel 21 is rotatably arranged on the fixing belt body 1, and the driven wheel group 22 includes a plurality of driven wheels 221, and the plurality of driven wheels 221 are arranged along the width direction of the fixing belt body 1; one end of the connecting rope 3 is arranged on the driving wheel 21, and the other end passes back and forth around each driven wheel 221 of the two driven wheel groups 22 in turn, and then is connected to the other driving wheel 21, and the driving wheel 21 can lock the position of the connecting rope 3 after rotation; specifically, there are two connecting ropes 3, one connecting rope 3 passes back and forth around the driven wheel 221 of the upper part and is connected to the other driving wheel 21, and the other connecting rope 3 passes back and forth around the driven wheel 221 of the lower part and is connected to the other driving wheel 21, and the driven wheel group 22 is closer to the end of the fixing belt body 1 than the driving wheel 21. Furthermore, the driving wheel 21 adopts a BOA knob buckle, and together with the connecting rope 3 forms a BOA system. After the driving wheel 21 is rotated, the position of the connecting rope 3 is locked, and then the distance between the two fixing belt bodies 1 is locked.

[0025] The ends of the two fixing belt bodies 1 away from the connecting rope 3 can be connected by Velcro. It should be understood that the two fixing belt bodies 1 can be connected into a ring structure by Velcro and the connecting rope 3. When using the device, the two fixing belt bodies 1 are wrapped around the patient through the two Velcros, and then the two driving wheels 21 are rotated to tighten the connecting rope 3, so that the two fixing belt bodies 1 are close together and tightened, thereby achieving the effect of stabilizing and fixing the patient's pelvis.

[0026] By rotating the two driving wheels 21, the connecting rope 3 is tightened and wound around the driving wheels 21. Since multiple driven wheels 221 are arranged along the width direction of the fixing belt body 1, the connecting rope 3 passes through the driven wheels 221 on both sides in sequence. When the connecting rope 3 is tightened, the two fixing belt bodies 1 can be evenly approached, so that the width of the gap between the two fixing belt bodies 1 is relatively consistent. By rotating the driving wheels 21, the tightness can be conveniently adjusted. The fixing belt bodies 1 on both sides are provided with driving wheels 21. By rotating the two driving wheels 21 at the same time, the two fixing belt bodies 1 can be quickly approached, so as to fit and fix the patient's pelvis.

[0027] In other schemes, a limiting ring 4 is further provided, and the limiting ring 4 is provided on the fixing belt body 1. The limiting ring 4 corresponds to the driven rotating wheel 221 one by one, and the driven rotating wheel 221 is provided in the limiting ring 4; the limiting ring 4 is provided with a through hole, and the connecting rope 3 passes through the through hole of the limiting ring 4 to bypass each driven rotating wheel 221. Specifically, the limiting ring 4 close to the driving rotating wheel 21 is provided with four through holes, which respectively correspond to the insertion and exit of the two connecting ropes 3; the remaining limiting rings 4 are each provided with two through holes, and the connecting rope 3 is inserted from one end and exits from the other end. By providing the limiting ring 4, the connecting rope 3 can be controlled to move in the limiting ring 4, so that the connecting rope 3 is maintained at the driving rotating wheel 21 or a position close to the driving rotating wheel 21.

[0028] In other schemes, a guide member 5 is further provided; the guide member 5 is provided on the fixing belt body 1, and a guide hole is provided on the guide member 5.

Specifically, the guide member 5, the driven rotating wheel 221 and the limiting ring 4 are respectively arranged on the fixing plate 6, and the guide member 5, the driven rotating wheel 221 and the limiting ring 4 can be more stably arranged through the fixing plate 6, and the strength of the fixing belt body 1 is enhanced at the same time.

[0030] In other embodiments, a plurality of air holes are provided on the fixing plate 6. By increasing the air holes, the air permeability of the device can be increased.

[0031] In other embodiments, a connecting belt 7 and a connecting ring 8 are further provided; a connecting belt 7 is further provided at one end of the fixing belt body 1 away from the connecting rope 3, and the two connecting belts 7 can pass through the connecting ring 8 and adhere to the fixing belt body 1 at the same time. It should be understood that the width of the connecting belt 7 is much smaller than that of the fixing belt. By connecting the two fixing belt bodies 1 with the connecting belt 7 instead of directly connecting the two fixing belt bodies 1, the width after connection can be reduced, so that the inguinal area and urethra can be better accessed for catheterization and / or femoral vein / artery access. It should also be understood that the back side of the connecting belt 7 can be well adhered to the fixing belt body 1.

[0032] In other schemes, the connecting belt 7 is a neoprene belt. By making the connecting belt 7 into a neoprene belt, the connecting belt 7 redundant after the connection can be easily cut off.
