Description

Technical Field

[0001] This utility model relates to the field of skin traction belt technology, specifically a skin traction belt for lower limb fractures in children. Background Technology

[0002] It is mainly used for conservative treatment of lower limb fractures or joint injuries such as femoral shaft fractures and hip / knee synovitis in children under 12 years old. The suspension traction method is suitable for children under 4 years old, and the horizontal traction method is suitable for children aged 5-8 years old. Through traction force and counter-traction force, it stabilizes the fracture ends, promotes reduction and healing, and relieves muscle spasm and swelling. The utility model with announcement number CN211433556U discloses a skin traction device for lower limb fractures, including a matching lower foot support and an upper foot support. Several fixing straps are fixedly attached to the lower foot support, which can fix the lower foot support and the upper foot support in place. The bottom of the lower foot support is also provided with a traction block, and the traction block has several traction through holes inside. It also includes a foot sleeve, which can be placed into the space formed by the lower foot support and the upper foot support. The above-mentioned technical solution has a simple structure. The foot sleeve is designed to protect the affected foot and reduce pressure on the skin and soft tissue of the foot. Compared with traditional skin traction devices, it has the advantages of large skin force-bearing area, no soft tissue pressure, convenient adjustment of the traction force direction of the affected limb, and comfort and breathability. However, children's skin tissue is delicate. Long-term tight wrapping can easily cause friction damage to the skin under gravity traction. Tight wrapping and lack of breathability can affect the breathability of skin tissue and easily cause heat sores in hot weather. Summary of the Invention

[0003] The purpose of this invention is to provide a skin traction belt for lower limb fractures in children, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A traction strap for lower limb fractures in children includes a connecting strap and a traction strap at the end of the connecting strap. The inner wall of the connecting strap is provided with a sponge pad for conforming to the skin tissue. The outer wall of the traction strap has a plurality of first ventilation holes for ventilation. The outer wall of the traction strap is provided with a plurality of first hook-and-loop fasteners located between the gaps of the first ventilation holes. A steel wire rope for traction is provided in the middle of the connecting strap. Each of the first hook-and-loop fasteners is provided with a restraint strap assembly for binding and positioning. A second vent is provided on the sponge pad at the position corresponding to the first vent. Several slots are provided on the inner side of the sponge pad at the gap between the second vents, and a silicone strip is provided in each slot.

[0005] Furthermore, the connecting strap is U-shaped, and reinforcing ribs are symmetrically provided at both ends of the connecting strap. A slot is provided on the end of the traction belt at the position corresponding to the reinforcing ribs.

[0006] In this invention, the reinforcing ribs are combined and fixed with the traction belt, which increases the toughness of the combination of the traction belt and the connecting strap, increases the tensile strength, facilitates the binding and fixation of the lower limbs, increases the binding force, and avoids breakage that could affect the recovery and use of the lower limbs.

[0007] Specifically, each end of the traction belt has a notch that penetrates the sponge pad. The traction belt is arc-shaped, and the inner wall of the traction belt is tightly fitted to the outer wall of the sponge pad.

[0008] In this invention, the notch helps the end of the traction belt to be distributed around the outer edge of the patient's lower limb, thus wrapping the lower limb. Furthermore, the sponge pad and the traction belt work together to fit tightly against the skin tissue of the patient's lower limb.

[0009] It is worth noting that the diameter of the second vent hole is adapted to the diameter of the first vent hole, the sponge pad is mesh-shaped, the width of the inner wall of the slot is adapted to the width of the outer wall of the silicone strip, and one of the outer wall surfaces of the silicone strip is tightly attached to and bonded to the inner wall surface of the slot.

[0010] In this invention, the second vent, in conjunction with the first vent, prevents the skin tissue of the lower limb from being wrapped and unable to breathe during lower limb wrapping and traction, thus avoiding the formation of ulcers. The second vent and the first vent penetrate and contact the corresponding skin tissue, which helps with ventilation. The silicone strip protrudes beyond the edge of the sponge pad by 0.5cm, increasing the friction with the skin tissue and reducing the sliding of the sponge pad on the lower limb, which affects fixation.

[0011] Furthermore, the first hook-and-loop fastener is fixed to the traction strap by needle and thread, the reinforcing rib and the connecting strap are integrally formed, the reinforcing rib extends into the slot, and the reinforcing rib and the traction strap are fixed by needle and thread.

[0012] In this invention, the reinforcement straps increase the toughness of the traction belt and connecting strap combination, reducing the impact of breakage on the traction fit of the lower limb skin. Secondly, the binding strap assembly includes a loop fastener and a second barbed fastener sewn together with the outer wall of the loop fastener. The loop fastener is bonded to the first barbed fastener. One end of the loop fastener wraps around and covers the second barbed fastener and is bonded to it.

[0013] In this invention, the looped hook and loop fasteners are bonded and fixed to the first barbed hook and loop fasteners to fix the position of the traction strap. The looped hook and loop fasteners cover the end of the same looped hook and loop fastener and are bonded and fixed to the second barbed hook and loop fasteners on the outer wall. This allows the restraint strap assembly to fix the two first barbed hook and loop fasteners on the same water surface. Multiple restraint strap assemblies can bind and fix the traction strap to the lower limbs, increasing the stability of wearing the garment.

[0014] It should be noted that the wire rope has a limiting ring at the left end, a fastening bolt at the middle of the left side of the limiting ring, a connecting rod at the left end of the wire rope, a screw hole at the end of the connecting rod, and a hook at the right end of the wire rope.

[0015] In this invention, the top of the wire rope passes through the connecting strap via a connecting rod, and a limiting ring is fitted onto the connecting rod. The fastening bolt passes through the limiting ring and is threadedly connected to the screw hole, thereby achieving a combination and fixation of the wire rope and the connecting strap. The wire rope passes through the roller on the external traction frame, and the bottom of the hook is attached to the corresponding counterweight, thereby achieving gravity-driven horizontal suspension traction.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model increases the toughness of the traction belt by combining and fixing a connecting strap with reinforcing ribs. A sponge pad with a second ventilation hole and silicone strip is bonded and fixed to the traction belt. The mesh-like structure of the sponge pad increases the comfort of the lower limbs. With the cooperation of the second and first ventilation holes, it helps the lower limbs to breathe and reduces the impact of blistering. With the cooperation of the silicone strip, the friction between the sponge pad and the lower limbs is increased, preventing slippage and affecting the binding of the traction belt. With the cooperation of the restraint strap assembly, the looped hook and loop fastener is first bonded to the first barbed hook and loop fastener to fix the position of the traction belt. The inner side of the looped hook and loop fastener wraps around and covers the other end and is bonded and fixed to the second barbed hook and loop fastener, increasing the stability of the traction belt wrap.

[0017] This utility model uses a steel wire rope with a limit ring, a connecting rod and a connecting strap inserted in the middle, and a fastening bolt to achieve the combination of the steel wire rope and the connecting strap. The end of the steel wire rope passes through the roller on the external traction frame, and the end of the hook is engaged with the corresponding counterweight belt to achieve gravity traction.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-7 This embodiment provides the following technical solution: A traction band for lower limb fractures in children includes a connecting strap 1 and a traction band 2 at the end of the connecting strap 1. The connecting strap 1 is U-shaped, and reinforcing ribs 10 are symmetrically provided at both ends of the connecting strap 1. A slot 23 is provided at the end of the traction band 2 corresponding to the reinforcing ribs 10.

[0022] In this invention, the reinforcing rib 10 is fixed together with the traction belt 2, which increases the toughness of the combination of the traction belt 2 and the connecting strap 1, increases the tensile strength, facilitates the binding and fixation of the lower limbs, increases the binding force, and avoids breakage that would affect the recovery and use of the lower limbs.

[0023] Furthermore, the inner wall of the connecting strap 1 is provided with a sponge pad 3 for conforming to the skin tissue, and the ends of the traction strap 2 are provided with notches 22, which penetrate the sponge pad 3. The traction strap 2 is arc-shaped, and the inner wall of the traction strap 2 is closely attached to the outer wall of the sponge pad 3.

[0024] In this invention, the notch 22 helps the end of the traction belt 2 to be distributed on the outer edge of the patient's lower limb, thus achieving a wrapping fit for the lower limb. Furthermore, the sponge pad 3, together with the traction belt 2, fits tightly against the outer skin tissue of the patient's lower limb.

[0025] Specifically, the outer wall of the traction belt 2 has several first ventilation holes 20 for ventilation, and several first barbed hook and loop fasteners 21 are provided on the outer wall of the traction belt 2 between the gaps of the first ventilation holes 20. The first barbed hook and loop fasteners 21 are fixed to the traction belt 2 by needle and thread. The reinforcing rib 10 and the connecting strap 1 are integrally formed. The reinforcing rib 10 extends into the slot 23 and is fixed to the traction belt 2 by needle and thread.

[0026] In this invention, the reinforcing rib 10 enhances the toughness of the traction belt 2 and connecting strap 1 combination, reducing the impact of breakage on the traction fit of the lower limb skin. It should be noted that a steel wire rope 5 for traction is provided in the middle of the connecting strap 1, and a binding strap assembly 4 for binding and positioning is provided at the corresponding position of the first barbed hook and loop fastener 21; the binding strap assembly 4 includes a hook and loop fastener 40 and a second barbed hook and loop fastener 41 sewn to the outer wall of the hook and loop fastener 40, the hook and loop fastener 40 is bonded to the first barbed hook and loop fastener 21, and one end of the hook and loop fastener 40 is wrapped around and covered on the second barbed hook and loop fastener 41 and bonded to it.

[0027] In this invention, the looped hook and loop fastener 40 is bonded and fixed to the first barbed hook and loop fastener 21 to fix the position of the traction strap 2. The looped hook and loop fastener 40 covers the top of the same looped hook and loop fastener 40 and is bonded and fixed to the second barbed hook and loop fastener 41 on the outer wall surface, so that the restraint strap assembly 4 fixes the two first barbed hook and loop fasteners 21 on the same water surface. Multiple restraint strap assemblies 4 bind and fix the traction strap 2 to the lower limbs, increasing the stability of wearing.

[0028] Furthermore, a second vent 30 is provided on the sponge pad 3 at the position corresponding to the first vent 20, and a number of slots 31 are provided on the inner side of the sponge pad 3 at the gap between the second vent 30, and a silicone strip 32 is provided in each slot 31.

[0029] Secondly, the diameter of the second vent 30 is matched with the diameter of the first vent 20, the sponge pad 3 is mesh-shaped, the width of the inner wall of the slot 31 is matched with the width of the outer wall of the silicone strip 32, and one of the outer wall surfaces of the silicone strip 32 is tightly attached to and bonded to the inner wall surface of the slot 31.

[0030] In this invention, the second vent 30, in conjunction with the first vent 20, prevents the skin tissue of the lower limb from being wrapped and not breathable during lower limb wrapping and traction, thus avoiding the formation of ulcers. The second vent 30 and the first vent 20 penetrate and contact the corresponding skin tissue, which helps with breathability. The silicone strip 32 protrudes beyond the edge of the sponge pad 3 by 0.5cm, increasing the friction with the skin tissue and reducing the sliding of the sponge pad 3 on the lower limb, which affects fixation.

[0031] It is worth adding that the left end of the wire rope 5 is provided with a limiting ring 50, the middle of the left side of the limiting ring 50 is provided with a fastening bolt 51, the left end of the wire rope 5 is provided with a connecting rod, the end of the connecting rod is provided with a screw hole 500, and the right end of the wire rope 5 is provided with a hook 52.

[0032] In this utility model, the top of the wire rope 5 passes through the connecting strap 1 via a connecting rod, and the limiting ring 50 is sleeved on the connecting rod. The fastening bolt 51 passes through the limiting ring 50 and is threadedly connected to the screw hole 500, thereby realizing the combination and fixation of the wire rope 5 and the connecting strap 1. The wire rope 5 passes through the roller on the external traction frame, and the bottom of the hook 52 is attached to the corresponding counterweight block, thereby realizing the gravity horizontal suspension traction cooperation.

[0033] In this embodiment of the pediatric lower limb fracture skin traction belt, when in use, the connecting strap 1 is first connected to the traction belt 2 by the reinforcing strap 10 and fixed by needle and thread. Then, the sponge pad 3 with silicone strip 32 is fixed to the inner wall of the traction belt 2 by needle and thread. The second ventilation hole 30 corresponds to the first ventilation hole 20.

The end of the fastening bolt 51 passes through the limiting ring 50 and is threadedly connected to the screw hole 500. The end of the steel wire rope 5 with hook 52 passes through the roller on the external traction frame, and the bottom of the hook 52 is used to hang the weight according to the required counterweight. The child first lies on the corresponding hospital bed, with the fractured lower limb requiring treatment lying flat on the bed. The sponge pad 3 is fitted and wrapped around the child's fractured lower limb, and the silicone strip 32 is in contact with the skin to increase friction and reduce the impact of the sponge pad 3 sliding on fixation. Then, the hook and loop fastener 40 is bonded to the two first barbed hook and loop fasteners 21 on the same vertical plane on the two traction straps 2, with the end of the hook and loop fastener 40 wrapping around and covering the other end, and bonding with the second barbed hook and loop fastener 41 on the outer wall of the hook and loop fastener 40. This achieves the traction strap 2 wrapping and fixing the lower limb. The restraint strap assembly 4 does not affect the internal ventilation of the second ventilation hole 30 and the first ventilation hole 20, reducing the impact of suffocation on skin tissue recovery. The counterweight on the hook 52 is adjusted according to the different degrees of lower limb fractures and ages of different patients, which helps with lower limb skin traction treatment and relieves muscle spasms and swelling.
