Description

Technical Field

[0001] This invention belongs to the field of orthopedic medical and nursing equipment technology, and in particular relates to a partially detachable orthopedic nursing brace. Background Technology

[0002] Orthopedic nursing braces are important auxiliary equipment in the clinical treatment and rehabilitation process of orthopedics. Their main functions are to provide stable support for injured bones, joints and surrounding soft tissues, restrict unnecessary movement, avoid secondary injury, and create a good biomechanical environment for tissue healing.

[0003] Traditional leg orthopedic braces typically consist of a support plate, fixation straps, and cushioning layers. The support plate, as the core support component, is usually a single, rigid, elongated structure with its length fixed during manufacturing. However, there are significant individual differences in leg length among patients; for example, the difference in leg length between adults and children is substantial. Even among adults, differences in height can lead to variations in thigh and calf lengths. This type of one-piece support plate cannot be adjusted to suit the patient's actual leg size. When used on patients with shorter legs, the ends of the support plate tend to extend beyond the leg's width, affecting daily activities (e.g., walking or sitting, potentially interfering with clothing or surrounding objects) and potentially causing localized pressure concentration due to misalignment. When used on patients with longer legs, the support plate cannot fully cover the area requiring support, resulting in insufficient stability and difficulty in effectively restricting movement of the injured area, increasing the risk of fracture displacement and poor ligament recovery. Summary of the Invention

[0004] The purpose of this invention is to provide a partially detachable orthopedic nursing brace that solves the problem that most existing partially detachable orthopedic nursing braces are one-piece designs and cannot be length-adjusted according to the patient's actual leg size by means of the coordination of the adjustment component and the fixation component.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0006] This invention relates to a partially detachable orthopedic nursing brace, comprising a fixation arm, a foot support assembly fixedly connected to the bottom of the fixation arm, an adjustment assembly at the top of the fixation arm, and fixing rings fixedly connected to both the top and bottom of the surface of the fixation arm. An arc-shaped plate is movably connected to the top of each fixing ring, and a telescopic strap is provided at one end of the arc-shaped plate. A fixing assembly is located at the top of the adjustment assembly, and the adjustment assembly includes an adjustment rod movably connected to the inner cavity of the fixation arm. A bolt hole is provided on one side of the adjustment rod, and an insertion hole is provided on the top of one side of the fixation arm. The inner cavity of the bolt hole is threaded with a limit bolt. The top of the adjusting rod is fixedly connected to a fixed seat. The inner cavity of the fixed seat is movably connected to a movable block. The top of the movable block is fixedly connected to a vertical rod. The fixing assembly includes a mounting ring. The inner cavity of the mounting ring is fixedly connected to the surface of the vertical rod. The top of the mounting ring has a groove. A spring is fixedly connected to one side of the inner cavity of the groove. One end of the spring is fixedly connected to a limit block. The top of the limit block is fixedly connected to a movable frame. The top of the movable frame is movably connected to a movable rod. One end of the movable rod is fixedly connected to a strap.

[0007] The invention is further configured such that the foot support assembly includes a foot support base, the top of which is fixedly connected to the bottom of a fixing arm. Limiting pads are fixedly connected to the front and rear sides of the inner cavity of the foot support base. Ventilation holes are provided on opposite sides of the limiting pads. Air inlets are provided on the front and back of the foot support base. Protective plates are fixedly connected to the front and rear sides of the top of the foot support base. When the patient places their foot into the inner cavity of the foot support base, the limiting pads on both sides of the inner cavity limit the movement of the patient's foot. The outlet of a miniature fan is connected to the air inlets as needed. The fan blows air onto the patient's foot through multiple ventilation holes to maintain comfort.

[0008] The present invention is further configured such that a soft plate is fixedly connected to the top and bottom of one side of the limiting pad, the soft plate being located above and below the vent hole respectively. The two soft plates are set on one side of the limiting pad to isolate the vent hole from the patient's foot, so as to prevent the patient's foot from blocking the vent hole and affecting the breathability of the foot.

[0009] The present invention is further configured such that a rear protective pad is fixedly connected to one side of the inner cavity of the foot support, and a front protective pad is fixedly connected to one side of the foot support. The soft rear protective pad can protect the patient's heel, and the front protective pad can support the patient's foot. When the patient's foot is small, the front protective pad can also limit the patient's toes to prevent the patient's foot from sliding in the inner cavity of the foot support.

[0010] The invention is further configured such that an adjusting bolt is connected through the inner cavity of the fixed base, and a knob is fixedly connected to one end of the adjusting bolt. By rotating the adjusting bolt with the knob, the movable block in the inner cavity of the fixed base can be reinforced, so that the vertical rod will not rotate easily.

[0011] The invention is further configured such that a limiting groove is formed on one side of the bottom of the mounting ring, a limiting piece is movably connected to the inner cavity of the limiting groove, the bottom of the limiting piece is fixedly connected to the surface of the movable frame, and the limiting piece moves with the movable frame in the inner cavity of the limiting groove. The limiting structure composed of the limiting groove and the limiting piece can improve the movement stability of the movable frame on the surface of the mounting ring.

[0012] The invention is further configured such that a binding strip is fixedly connected to one end of the telescopic belt away from the arc-shaped plate. The binding strip is made of non-woven fabric. After pulling the two sections of the binding strip around the patient's limb, they are tied tightly, thereby fixing the patient's limb to one side of the fixed arm.

[0013] The invention is further configured such that a male Velcro is provided at the top of the strap and a female Velcro is provided at the bottom of the strap. After pulling the two sections of the strap and wrapping them around the patient's limb, the male Velcro on one side of the strap is attached to the female Velcro on the other side of the strap, thereby fixing the upper part of the patient's limb to one side of the fixation arm.

[0014] The present invention is further configured such that a fixed sleeve is fixedly connected to the top of the surface of the fixed arm, and the surface of the fixed seat is movably connected to the inner cavity of the fixed sleeve. When the adjusting rod moves up and down, the fixed seat at its top moves in the inner cavity of the fixed sleeve. As the adjusting rod continues to move up, the adjusting rod also moves in the inner cavity of the fixed sleeve. Through the limiting effect of the fixed sleeve, the stability of the adjusting rod and the fixed seat when moving up and down can be improved.

[0015] The invention is further configured such that a heel pad is fixedly connected to one side of the bottom of the foot support, and a forefoot pad is fixedly connected to the bottom of the foot support away from the heel pad. The heel pad and the forefoot pad can support the bottom of the foot support, mimicking the characteristics of a shoe. The material of the heel pad and the forefoot pad is relatively soft, which can greatly improve the comfort of the patient's feet.

[0016] The present invention has the following beneficial effects: 1. This invention solves the core problem of poor adaptability of traditional integrated braces. The length can be flexibly adjusted by adjusting the components. Only by turning the limiting bolt, moving the adjusting rod and then fixing it again is required. No professional tools are needed. It can accurately adapt to the leg size of various patients, such as adults and children, and adults of different heights. It avoids the problems of traditional braces that interfere with walking and sitting posture and cause local pressure concentration when they are too long. It also eliminates the situation where the support range is insufficient and the risk of fracture displacement is increased due to the brace being too short. It greatly improves the adaptability to individual differences.

[0017] 2. This invention achieves a balance between support stability and user experience: The limb is stably fixed to one side of the fixation arm using a combination of straps and Velcro fasteners, along with an arc-shaped plate, effectively restricting movement of the injured area. The joint design allows the structure to be adjusted to the back of the knee, allowing the patient to bend the joint appropriately. The knob can also be used to switch between movement and fixation modes as needed, meeting different needs for daily activities and reinforcement correction. In addition, the combination of a mini fan and ventilation holes can continuously blow air onto the foot, solving the problem of stuffiness caused by prolonged wear of traditional braces, thus balancing support effectiveness and user comfort.

[0029] Please see Figure 1-9 This invention relates to a partially detachable orthopedic nursing brace, comprising a fixed arm 1, a foot support assembly 2 fixedly connected to the bottom of the fixed arm 1, an adjusting assembly 3 at the top of the fixed arm 1, and fixed rings 4 fixedly connected to both the top and bottom of the fixed arm 1. An arc-shaped plate 5 is movably connected to the top of the fixed rings 4, and a telescopic strap 6 is provided at one end of the arc-shaped plate 5. A fixed assembly 7 is provided at the top of the adjusting assembly 3. The adjusting assembly 3 includes an adjusting rod 301, which is movably connected to the inner cavity of the fixed arm 1. A bolt hole 302 is provided on one side of the adjusting rod 301, and an insertion hole 303 is provided on the top of one side of the fixed arm 1. A limit bolt 30 is threadedly connected to the inner cavity of the bolt hole 302. 4. A fixed base 305 is fixedly connected to the top of the adjusting rod 301. A movable block 306 is movably connected to the inner cavity of the fixed base 305. A vertical rod 307 is fixedly connected to the top of the movable block 306. The fixing assembly 7 includes a mounting ring 701. The inner cavity of the mounting ring 701 is fixedly connected to the surface of the vertical rod 307. A groove 702 is provided on the top of the mounting ring 701. A spring 703 is fixedly connected to one side of the inner cavity of the groove 702. A limit block 704 is fixedly connected to one end of the spring 703. A movable frame 705 is fixedly connected to the top of the limit block 704. A movable rod 706 is movably connected to the top of the movable frame 705. A strap 707 is fixedly connected to one end of the movable rod 706.

[0030] Specifically: Based on the length of the patient's leg, the length of the nursing brace is adjusted using the adjusting component 3. The adjustment method is as follows: Tighten the limiting bolt 304 until one end disengages from the bolt hole 302 on the surface of the adjusting rod 301. Then, move the adjusting rod 301 up and down until the length of the adjusting rod 301 and the fixing arm 1 is suitable for the length of the patient's leg. Tighten the limiting bolt 304 again until one end screws into the bolt hole 302 on the surface of the adjusting rod 301. The patient places their foot into the inner cavity of the footrest 201 and pulls on the two binding rings respectively. The bandage is tied tightly around the back of the patient's limb, thereby fixing the patient's limb to one side of the fixation arm 1 through the arc plate 5 and the strap 707. Finally, after pulling the two sections of the strap 707 and twisting them around the patient's limb, the male Velcro on one side of the strap 707 is attached to the female Velcro on the other side of the strap 707, thereby fixing the upper part of the patient's limb to one side of the fixation arm 1. The length of the brace is adjusted by the adjusting component 3 so that the joint structure formed by the fixation seat 305 and the movable block 306 is located behind the patient's knee, which facilitates the appropriate bending of the patient's joint.

[0031] The foot support assembly 2 includes a foot support base 201, the top of which is fixedly connected to the bottom of the fixing arm 1. Limiting pads 202 are fixedly connected to the front and rear sides of the inner cavity of the foot support base 201. Ventilation holes 203 are provided on opposite sides of the limiting pads 202. Air inlets 204 are provided on the front and back of the foot support base 201. Protective plates 205 are fixedly connected to the front and rear sides of the top of the foot support base 201. Flexible plates are fixedly connected to the top and bottom of one side of the limiting pads 202, respectively located above and below the ventilation holes 203. A rear protective pad is fixedly connected to one side of the inner cavity of the foot support base 201, and a front protective pad is fixedly connected to one side of the foot support base 201. The inner cavity of the fixing arm 305 is permeable to... An adjusting bolt 8 is attached, and a knob 9 is fixedly connected to one end of the adjusting bolt 8. A limit groove is opened on one side of the bottom of the mounting ring 701. A limit piece is movably connected to the inner cavity of the limit groove. The bottom of the limit piece is fixedly connected to the surface of the movable frame 705. A binding strip is fixedly connected to the end of the telescopic belt 6 away from the arc plate 5. The binding strip is made of non-woven fabric. A male Velcro is provided at the top of the binding strap 707, and a female Velcro is provided at the bottom of the binding strap 707. A fixing sleeve is fixedly connected to the top of the surface of the fixing arm 1. The surface of the fixing seat 305 is movably connected to the inner cavity of the fixing sleeve. A heel pad is fixedly connected to one side of the bottom of the foot support seat 201, and a forefoot pad is fixedly connected to the bottom of the foot support seat 201 and the side away from the heel pad.

[0032] Specifically: The patient places their foot into the inner cavity of the footrest 201. The limiting pads 202 on both sides of the inner cavity of the footrest 201 limit the movement of the patient's foot. The outlet of the miniature fan is connected to the air inlet 204 as needed. The fan blows air onto the patient's foot through multiple ventilation holes 203, maintaining comfort. Two soft plates are placed on one side of the limiting pads 202, isolating the ventilation holes 203 from the patient's foot to prevent the foot from blocking the ventilation holes and affecting airflow. The soft back pad protects the patient's heel, while the front pad supports the patient's foot. When the patient's foot is small, the front pad also limits the toes, preventing the foot from sliding within the inner cavity of the footrest 201. Rotating the adjusting bolt 8 via the knob 9, in conjunction with the nut on the surface of the adjusting bolt 8, reinforces the movable block 306 within the inner cavity of the fixed base 305, preventing the vertical rod 307 from rotating easily. The limiting plate moves with the moving frame 705. The movement of the inner cavity of the groove, through the limiting structure composed of the limiting groove and the limiting piece, can improve the movement stability of the moving frame 705 on the surface of the mounting ring 701. After pulling the two sections of the binding strip around the patient's limb and tightening them, the patient's limb is fixed to one side of the fixing arm 1. After pulling the two sections of the binding strap 707 around the patient's limb, the male Velcro on one side of the binding strap 707 is attached to the female Velcro on the other side of the binding strap 707, thereby fixing the upper part of the patient's limb to one side of the fixing arm 1. When the adjusting rod 301 is moved up and down, the fixing seat 305 at its top will move in the inner cavity of the fixing sleeve. As the adjusting rod 301 continues to move upward, the adjusting rod 301 will also move in the inner cavity of the fixing sleeve. Through the limiting effect of the fixing sleeve, the stability of the adjusting rod 301 and the fixing seat 305 when moving up and down can be improved. The heel pad and the forefoot pad can support the bottom of the foot support seat 201, mimicking the characteristics of a shoe. Moreover, the material of the heel pad and the forefoot pad is relatively soft, which can greatly improve the comfort of the patient's feet.

[0033] The working principle of this invention is as follows: First, based on the length of the patient's leg, the length of the nursing brace is adjusted using the adjusting component 3. Specifically, the adjustment method is as follows: Tighten the limiting bolt 304 until one end disengages from the bolt hole 302 on the surface of the adjusting rod 301. Then, move the adjusting rod 301 up and down until the length of the adjusting rod 301 and the fixing arm 1 is suitable for the length of the patient's leg. Tighten the limiting bolt 304 again until one end is screwed into the bolt hole 302 on the surface of the adjusting rod 301. The patient places their foot into the inner cavity of the footrest 201 and brings their leg close to the fixing arm 1. Pull the two straps around the patient's limb and tighten them. This fixes the patient's limb to one side of the fixing arm 1 through the arc plate 5 and the strap 707. Finally, after pulling the two straps 707 around the patient's limb, attach the male Velcro on one side of the strap 707 to the female Velcro on the other side of the strap 707. This secures the patient's limb. The upper part of the brace is fixed to one side of the fixed arm 1. The length of the brace is adjusted by the adjusting component 3 so that the joint structure composed of the fixed seat 305 and the movable block 306 is located behind the patient's knee, which facilitates the appropriate bending of the patient's joint. When the patient's joint bends, the movable frame 705 will move on the surface of the mounting ring 701. When the patient's joint returns to its original position, the movable frame 705 will return to its original position under the action of the spring 703. When daily exercise is not required, the adjusting bolt 8 can be turned by the knob 9. With the nut on the surface of the adjusting bolt 8, the movable block 306 in the inner cavity of the fixed seat 305 can be reinforced, so that the vertical rod 307 will not easily rotate, thereby enhancing the corrective and reinforcing effect of the brace on the patient's limb. As needed, the air outlet of the miniature fan can be connected to the air inlet 204. The fan blows air to the patient's feet through multiple ventilation holes 203 to maintain the comfort of the patient's feet.
