Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an early patellar activity massage device after trauma treatment, which is used to promote multi-directional rehabilitation activities of the patella and prevent secondary injuries to the knee joint. Background Art

[0002] The knee joint is one of the important joints of the lower extremities, bearing the weight of the body and various movement loads of the lower extremities. After the treatment of knee joint trauma (such as patellar fracture, ligament injury), if reasonable functional exercises are not carried out, it will affect the daily function requirements of the knee joint.

[0003] At present, the existing rehabilitation methods in clinical practice mainly rely on the passive flexion and extension movements of the knee joint by patients and the manual assistance of physical therapists, and there are the following deficiencies:

[0004] 1. Insufficient multi-directional movement of the patella. Currently, commercially available CPM machines (continuous passive motion devices) mainly focus on the flexion and extension training of the knee joint, with weak pertinence to patellar movement, and cannot effectively promote the multi-directional movement of the patella, resulting in adhesion of the tissues around the patella, affecting the range of motion of the knee joint, and the device cannot well adapt to patients with different leg lengths, affecting the rehabilitation exercise effect; although commercially available CPM machines (continuous passive motion devices) can achieve flexion and extension of the knee joint, the improvement of the multi-directional movement of the patella is insufficient;

[0005] 2. Inflexible dynamic adjustment of exercise. Most of the existing devices assist patients in passive exercise or active exercise in bed, and when the knee joint is flexed and the patient walks actively, they cannot provide effective support and protection, and cannot autonomously adjust the range of flexion and extension of the knee joint according to the recovery stage, weakening the rehabilitation exercise effect of the patient;

[0006] 3. Lack of risk protection. Currently, when patients are walking and exercising, they are prone to sudden knee joint flexion due to insufficient joint support force, which is likely to cause secondary injuries to the knee joint of patients and affect the healing of fractures and ligaments. Therefore, a structure that can brake when the patient's knee joint suddenly bends needs to be designed. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides the following technical solutions:

[0008] An early patellar activity massage device after trauma treatment, including a leg protection component, the leg protection component includes a lower telescopic rod, an upper telescopic rod, a fixing belt, a rotator and a massager, the rotator is fixedly installed at the upper end of the lower telescopic rod, the lower end of the upper telescopic rod is rotatably connected to the rotator, and the massager is detachably installed on the rotator;

[0009] The rotator includes a rotating base, a limit bolt, and a one-way locking mechanism. The upper telescopic rod is rotatably installed on the rotating base. The one-way locking mechanism restricts the rapid rotation of the upper telescopic rod, the limit bolt restricts the rotation range of the upper telescopic rod, and by adjusting the position of the limit bolt installed on the rotating base, the rotation range of the upper telescopic rod is adjusted.

[0010] The massager includes a massage base and a massage cover. A control panel is provided on one side of the massage base. The massage cover is movably installed below the massage base, and a driving mechanism is provided on the massage base to control the massage cover to swing in four directions: up, down, left, and right. A number of heating plates are provided on the massage cover.

[0011] Further, a rotating groove is provided on the rotating base, and the upper telescopic rod rotates within the rotating groove. A number of limit holes are provided on the rotating base corresponding to the position of the rotating groove. The limit bolt is threadedly installed in the limit holes and passes through the rotating groove. The rotation range of the upper telescopic rod is restricted by the cooperation of the limit bolt and the rotating groove; the rotation range of the upper telescopic rod is adjusted by inserting the limit bolt into different limit holes.

[0012] Further, a side soft pad or a poultice bag is detachably provided on the side of the rotating base facing away from the limit holes; both the side soft pad and the poultice bag are detachably connected to the rotating base through Velcro.

[0013] Further, the one-way locking mechanism includes an internal gear disk, a movable plate, a rotating rod, and an elastic element. The internal gear disk is fixedly installed on the rotating base. The movable plate is located within the internal gear disk. A structure meshing with the internal gear disk is provided on the outer edge of the movable plate. A special-shaped groove is provided in the movable plate, and the rotating rod is located within the special-shaped groove. The lower end of the upper telescopic rod is rotatably connected to the rotating base through a fixedly provided rotating shaft. The rotating rod is fixedly installed on the rotating shaft, and one end of the rotating rod is connected to the movable plate through an elastic element, so that the rotation center of the movable plate coincides with the rotation center of the rotating rod. When the upper telescopic rod is rotated slowly and uniformly, the rotating rod is driven to rotate and resist the rotation of the movable plate. When suddenly accelerating the rotation, the rotating rod compresses the elastic element, causing the rotation center of the movable plate to deviate from the rotation center of the rotating rod, so that the outer edge of the movable plate meshes with the internal gear disk, thereby restricting the one-way rotation of the movable plate and the rotating rod. When the upper telescopic rod is rotated in the reverse direction, under the action of the elastic element, the rotation center of the movable plate resumes coincidence with the rotation center of the rotating rod.

[0014] Further, the massage cover is an arc-shaped cover that fits the human patella structure. A groove is provided below the massage base, and the massage cover is located within the groove. A spherical groove is provided within the massage base, and a ball head is fixedly provided above the massage cover. The ball head is movably installed within the spherical groove. The movable connection between the massage cover and the massage base is achieved through the cooperation of the ball head and the spherical groove to ensure stable swinging; both sides of the massage base are detachably connected to the rotator through fixing straps.

[0015] Further, there are four driving mechanisms respectively installed in the four directions of up, down, left and right of the massage seat. Planes are opened on the outer arc surface of the massage cover at positions corresponding to the driving mechanisms. The driving mechanism includes a motor and a cam fixedly arranged on the output shaft of the motor. The cam is driven by the motor to rotate and abut against the plane on the massage cover, pushing the massage cover to swing.

[0016] Further, a positive soft pad is arranged below the massage cover, a heating plate is arranged in the positive soft pad, and a power supply is arranged in the massage seat.

[0017] Further, a number of adjustable strap assemblies are linearly arranged on both the upper telescopic rod and the lower telescopic rod. The adjustable strap assembly includes two arc-shaped plates; one ends of the two arc-shaped plates of the adjustable strap assembly on the upper telescopic rod are respectively hinged on both sides of the upper telescopic rod, and the other ends of the two arc-shaped plates are connected and closed through a fixing strap; one ends of the two arc-shaped plates of the adjustable strap assembly on the lower telescopic rod are respectively hinged on both sides of the lower telescopic rod, and the other ends of the two arc-shaped plates are connected and closed through a fixing strap.

[0018] Further, a walking stick is movably installed at the upper end of the upper telescopic rod. A connector is fixedly installed at the upper end of the upper telescopic rod. The connector includes a ball head structure and a connecting cylinder. The outer shell of the ball head structure is fixedly installed on the upper telescopic rod. The connecting cylinder is fixedly connected to the ball core of the ball head structure. The walking stick movably passes through the connecting cylinder.

[0019] Further, a foot plate is rotatably installed at the lower end of the lower telescopic rod, and a fixing strap is arranged on the foot plate.

[0020] In view of the three major deficiencies proposed in the background art, the technical solution of the present application has the following beneficial effects:

[0021] 1. Aiming at the existing deficiency 1, the present invention designs a rotator to connect the upper telescopic rod and the lower telescopic rod. During use, the patient's sole is fixed on the foot plate through a fixing strap, and then the arc-shaped plates of the adjustable strap assembly are connected and closed through the fixing strap, thereby binding the upper telescopic rod and the lower telescopic rod to the patient's thigh and calf. The rotator can be adjusted to the outside of the knee joint according to the leg lengths of different patients through the telescoping of the upper telescopic rod and the lower telescopic rod, realizing the adaptation for patients with different leg lengths.

[0022] 2. Regarding the existing deficiency 2, the present invention opens a rotating groove on the rotating seat of the rotator, enabling the upper telescopic rod to rotate within the rotating groove, and opening a number of limiting holes at positions corresponding to the rotating groove on the rotating seat. By threadedly installing the limiting bolts in the limiting holes and cooperating with the rotating groove, the rotation range of the upper telescopic rod is restricted; and by inserting the limiting bolts into different limiting holes, the rotation range of the upper telescopic rod can be adjusted, thus realizing flexible adjustment of the maximum allowable range of joint movement according to the patient's recovery situation, playing a protective role while also enhancing the effect of rehabilitation training;

[0023] 3. Regarding the existing deficiency 3, the present invention sets a one-way locking mechanism on the rotator. When the patient is walking and exercising, the patient is prone to sudden knee joint bending due to insufficient joint support force. At this time, it drives the upper telescopic rod to rotate rapidly, causing the rotating rod of the one-way locking mechanism to rotate rapidly, compressing the elastic element of the movable plate, making the rotation center of the movable plate deviate from the rotation center of the rotating rod, and making the movable plate get stuck on the internal gear disc of the one-way locking mechanism, thereby restricting the further one-way rotation of the rotating rod and restricting the continued one-way rotation of the upper telescopic rod, thus preventing the knee joint from continuing to bend, and can well prevent secondary injury to the knee joint caused by sudden knee joint bending, as well as affecting the healing of fractures and ligaments;

[0024] 4. The present invention detachably connects a massager to the rotator through a fixing strap. When in use, the massager is bound above the knee joint through the fixing strap, making the massage cover of the massager stick to the patella, and motors are arranged in four directions of up, down, left, and right on the massage seat of the massager. The cams are respectively driven by the motors in the four directions of up, down, left, and right to rotate and press against the plane on the massage cover, pushing the massage cover to swing the patella in four directions of down, up, right, and left respectively, thereby realizing the movement of the patella, and a heating plate is arranged on the massage cover to heat the patella, avoiding adhesion of tissues around the patella and affecting the mobility of the knee joint; and the side soft pad can be replaced with a dressing bag through Velcro on the rotating seat. Ice compress materials can be loaded into the dressing bag, which can relieve pain and inflammatory irritation after rehabilitation exercise and assist in improving the rehabilitation effect.
