Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an orthopedic splint. Background Art

[0002] An orthopedic splint is an external medical device used to immobilize and support patients with fractures or bone injuries. Its main purpose is to limit the movement of the injured part to promote fracture healing and relieve pain.

[0003] Traditional orthopedic splints are mainly composed of a splint and a bandage with Velcro. Velcro is a common fixation method and is widely used in orthopedic splints due to its ease of operation. However, the inherent design and material properties of Velcro also cause some problems that cannot be ignored:

[0004] First, the double-layer structure design of Velcro makes the splint appear thicker after wearing. This thickness not only increases the weight of the splint, but also causes a stuffy feeling in the wearing area, especially in a high temperature environment or when worn for a long time, the patient will feel obvious discomfort; secondly, the adhesion of Velcro will gradually weaken over time and repeated use, resulting in a decrease in the fixation effect, requiring patients to frequently adjust to maintain appropriate fixation strength; in addition, Velcro is relatively difficult to clean due to its surface structure that easily absorbs dust and fibers. Improper cleaning methods may also accelerate the damage of Velcro. Once Velcro gets damp or stained with difficult-to-remove stains, its viscosity and service life will be affected. Therefore, we propose an orthopedic splint to solve the above problems. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] An orthopedic splint comprises: a base, the base being rectangular, having strip grooves on both sides of the base, and having sockets connected to the strip grooves on both sides of the front end;

[0007] An arc-shaped splint is arranged directly above the base, a T-shaped plate is fixed on the top of the arc-shaped splint, and U-shaped notches are constructed at equal intervals on the sides of the T-shaped plate;

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] The present application provides an orthopedic splint, which is mainly used to solve the problem that the double-layer structure design of Velcro in the prior art makes the splint appear thick after wearing. This thickness not only increases the weight of the splint, but also causes a stuffy feeling in the wearing area, especially in a high temperature environment or when worn for a long time, the patient will feel obvious discomfort, and provides the following technical solutions, which will be combined with Figure 1-Figure 4 Give detailed instructions:

[0029] An orthopedic splint, comprising:

[0030] The base 1 is rectangular, with strip grooves 101 on both sides of the base 1 and jacks 102 connected to the strip grooves 101 on both sides of the front end;

[0031] The arc-shaped splint 2 is arranged directly above the base 1. A T-shaped plate 3 is fixed on the top of the arc-shaped splint 2. U-shaped notches 301 are constructed at equal intervals on the sides of the T-shaped plate 3.

[0032] The connecting belt 4 is evenly spaced and connected to the upper sides of the base 1. The other end of the connecting belt 4 is connected to the elastic cord 5. The side of the elastic cord 5 away from the connecting belt 4 is embedded in the U-shaped notch 301, and the surface of the elastic cord 5 is evenly spaced with knots 501.

[0033] The extension plate 6 is movably arranged at the front end of the base 1. A connecting plate 601 is fixedly provided at one end of the extension plate 6 close to the base 1. The connecting plate 601 slides and is inserted into the socket 102.

[0034] A locking member 7 is disposed in the strip groove 101 and is used to prevent the connecting plate 601 from moving forward and backward;

[0035] The clamping mechanism 8 is provided on the top of the extension plate 6 and is used to clamp and fix the patient's foot.

[0036] It should be noted that this device is mainly used to fix and treat fractures in the patient's lower leg. The base 1 and the splint are both made of PVC material. The base 1 provides a stable support platform, and the arc-shaped splint 2 is combined with the base 1 to form a fixed structure, which limits the movement of the fracture site.

[0037] The orthopedic splint workflow:

[0038] The first step is to place the base 1 of the orthopedic splint under the patient's fracture site, and at the same time place the arc splint 2 above the patient's limb, pull the connecting belt 4, and according to the shape and size of the patient's limb, embed the appropriate knot 501 on the elastic cord 5 into the U-shaped notch 301, thereby ensuring that the connecting belt 4 has appropriate tightness. Compared with traditional Velcro fixation, the operation is relatively simple and there will be no stuffiness.

[0039] In the second step, according to the patient's needs, the extension plate 6 is pulled to adjust its position, and the connecting plate 601 is fixed by the locking member 7 to ensure the stability of the extension plate 6;

[0040] The third step is to fix the patient's foot by the clamping mechanism 8, so as to prevent the twisting of the patient's foot from affecting the recovery of the fracture site and achieve a better treatment effect.

[0041] like Figure 4 As shown, in some embodiments, the U-shaped notches 301 on both sides are staggered front to back, and the U-shaped notch 301 on one side corresponds to the position of the connecting strap 4 on the other side. More specifically, this design ensures that the connecting strap 4 can be evenly distributed around the patient's limb when fixed, thereby providing balanced pressure and support. This design helps to reduce pressure points, avoid local discomfort, and ensure the stability of the entire splint system.

[0042] like Figure 1 As shown, in some embodiments, the diameter of the knot 501 is larger than the width of the U-shaped notch 301. More specifically, because the diameter of the knot 501 is larger than the width of the notch, the knot 501 cannot slip out of the notch. This ensures that the elastic cord 5 remains stable after being fixed and will not loosen due to patient movement or external force.

[0043] like Figure 1 As shown, in some embodiments, limit frames 302 are fixed at equal intervals on the top of the arc-shaped splint 2, and the elastic cord 5 is inserted into the limit frames 302. More specifically, since the limit frames 302 are fixed at equal intervals on the top of the arc-shaped splint 2, they provide a clear path for the elastic cord 5, ensuring that the elastic cord 5 will not deviate from the predetermined position during the adjustment and fixing process.

[0044] like Figure 2 As shown, in some embodiments, the top surface of the base 1 is an arc-shaped surface. More specifically, the arc-shaped design can better fit the natural curve of the human body, so that the splint fits more closely to the patient's legs. Due to the higher fit, the splint is not easily displaced when the patient moves, thereby reducing the risk of secondary injury caused by improper fixation and improving comfort and fixation effect.

[0045] like Figure 3 As shown, in some embodiments, the locking member 7 includes a sliding rod 701 that slides through the end side of the connecting plate 601, and the groove wall of the strip groove 101 is constructed with circular through holes 103 at equal intervals. The sliding rod 701 slides through the circular through hole 103, and its two ends are hinged with limiting plates 702. More specifically, the sliding rod 701 can slide through the circular through hole 103. The use of the limiting plate 702 ensures that the sliding rod 701 will not move easily after being inserted into the circular through hole 103, which provides good stability for the splint. Since the sliding rod 701 can slide in the circular through hole 103, this design allows doctors or caregivers to adjust the fixed position of the connecting plate 601 according to the specific situation of the affected part, thereby providing a more precise fixation effect for the foot.

[0046] like Figure 3 As shown, in some embodiments, the clamping mechanism 8 includes a corner frame 801 fixed to the end side of the extension plate 6, and mounting holes 8011 are constructed on both sides of the corner frame 801. A guide rod 802 is connected between the hole walls of the mounting hole 8011, and a slider 803 is slidingly sleeved on the surface of the guide rod 802. A resistance rod 804 is connected between the two sliders 803, and a spring 805 is connected between the slider 803 and the hole wall of the mounting hole 8011. The spring 805 is sleeved on the surface of the guide rod 802. More specifically, when in use, the medical staff can pull the resistance rod 804 upward with their hands, and this spring 805 is in a compressed state. After the patient's foot passes through the resistance rod 804, the hand is released. Under the elastic force of the spring 805, the resistance rod 804 can clamp and fix the patient, thereby preventing the patient's foot from twisting and affecting the recovery of the fracture site.

[0047] like Figure 3As shown, in some embodiments, the guide rod 802 is set at an angle, and the surface of the interference rod 804 is covered with a rubber sleeve. More specifically, the inclined setting of the guide rod 802 conforms to the principles of ergonomics, can better adapt to the natural curve of the human leg, and achieve a better fixation effect. The rubber sleeve is made of soft material, which can reduce the friction and pressure between the interference rod 804 and the patient's skin, thereby improving wearing comfort.

[0048] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
