Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pelvic bone fixing technology, and specifically relates to a pelvic bone fixing belt. BACKGROUND

[0002] Pelvic fractures account for about 3% of all fractures. Major bleeding from pelvic fractures occurs mainly due to the presence of many major blood vessels in the pelvis and the high vascularity of the organs in the pelvis. In addition, retroperitoneal hemorrhage can be a major complication that leads to up to 6 liters of blood loss. When pelvic trauma occurs, quickly and effectively fixing the hip is necessary to reduce the risk of complications. Traditionally, a bed sheet is used to fix the pelvis, but this method is difficult to adjust the optimal tightness, and the bed sheet will loosen over time.

[0003] To solve this problem, relevant personnel proposed a pelvic bone fixing belt as shown in CN210114551U, which adjusts the tightness of the fixing belt by tightening both sides when the fixed pulley is rotated. However, after rotating to the desired position, the limiting structure needs to be operated additionally to avoid the fixed pulley from being reversed due to the extrusion of the human body, which causes the connecting rope to loosen. This process is still not simple and is more troublesome. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a pelvic bone fixing belt to solve the technical problem that the existing fixing belt needs to be limited after being rotated to the desired position to avoid loosening.

[0005] To solve the technical problem, the utility model adopts the following technical scheme:

[0006] A pelvic bone fixing belt, comprising a belt body, a first connecting plate, a rotating assembly, a limiting assembly, a connecting rope, a first rotating wheel set, a second connecting plate, and a second rotating wheel set;

[0007] The belt body is connected to the first connecting plate, the rotating assembly and the limiting assembly are rotatably arranged on the first connecting plate, and the limiting assembly can limit the reverse rotation of the rotating assembly;

[0008] The first rotating wheel set is rotatably arranged on the first connecting plate, the second rotating wheel set is rotatably arranged on the second connecting plate, one end of the connecting rope is connected to the rotating assembly, and the other end is connected to the second connecting plate after being wound back and forth through the first rotating wheel set and the second rotating wheel set in sequence;

[0009] The end of the belt body away from the first connecting plate is detachably arranged on the second connecting plate.

[0010] Further, the rotating assembly comprises a winding rotating shaft and a ratchet wheel; the winding rotating shaft is rotationally connected to the first connecting plate and fixedly connected with the connecting rope; the ratchet wheel is coaxially fixed to the winding rotating shaft, and the limiting assembly can limit reverse rotation of the ratchet wheel.

[0011] Further, the limiting assembly comprises a limiting connecting rod, a torsional spring and a pawl; the limiting connecting rod is vertically arranged on the first connecting plate, the pawl is rotationally arranged on the limiting connecting rod and connected with the first connecting plate through the torsional spring, and the pawl can limit reverse rotation of the ratchet wheel.

[0012] Further, the first rotating wheel set and the second rotating wheel set each comprise a plurality of rotating wheel bodies, and a limiting groove is arranged around the side surface of each rotating wheel body, and the connecting rope is wound around the limiting groove.

[0013] Further, the second connecting plate is further provided with a long hole, and the belt body is further provided with a magic tape, and the belt body can be connected into a loop through the magic tape by passing through the long hole.

[0014] Compared with the prior art, the application has the following advantages:

[0015] By rotating the rotating assembly in the forward direction, the connecting rope is gradually wound and tightened, the distance between the first connecting plate and the second connecting plate can be changed, the connecting rope is wound around the first rotating wheel set and the second rotating wheel set back and forth, so that the force on the second connecting plate is relatively uniform when the second connecting plate approaches the first connecting plate; at the same time, since the limiting assembly limits reverse rotation of the rotating assembly, when the connecting rope is tightened to the required tightness, locking is not required, the limiting assembly spontaneously limits reverse rotation of the rotating assembly, i.e. the connecting rope is loosened.

DETAILED DESCRIPTION

[0021] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings.

It should be understood that the limiting assembly 4 does not limit the forward rotation of the rotating assembly 3.

[0024] The first rotating wheel set 6 is rotatably arranged on the first connecting plate 2, the second rotating wheel set 8 is rotatably arranged on the second connecting plate 7, one end of the connecting rope 5 is connected with the rotating assembly 3, and the other end is connected with the second connecting plate 7 after being wound back and forth through the first rotating wheel set 6 and the second rotating wheel set 8 in sequence. It should be understood that the connecting rope 5 is wound through the second rotating wheel set 8 after being wound through the first rotating wheel set 6, and then wound through the first rotating wheel set 6 again, and the process is repeated until the end of the connecting rope 5 is fixedly connected with the second connecting plate 7 after being wound through the first rotating wheel set 6 or the second rotating wheel set 8. Specifically, the first rotating wheel set 6 and the second rotating wheel set 8 are oppositely arranged. By rotating the rotating assembly 3 forward, the connecting rope 5 can be gradually wound on the rotating assembly 3.

[0025] The end of the band body 1 away from the first connecting plate 2 is detachably arranged on the second connecting plate 7.
