[0002] As the incidence of stroke increases year by year, the age of onset gradually becomes younger. According to the combined urban and rural areas, stroke has become the leading cause of death in my country and the leading cause of disability among Chinese adults. Stroke has the characteristics of high morbidity, high mortality and high disability rate. Once a stroke occurs, it will cause obstacles in many aspects such as movement, language and consciousness. Studies have shown that 55% to 75% of stroke patients may experience hemiplegia. The prognosis of stroke is poor, and many patients will have sequelae of varying degrees. Attention should be paid to rehabilitation training to achieve relatively ideal clinical results and strive for better prognosis. In addition, in clinical practice, stroke patients will have deep vein thrombosis due to the hypercoagulable state of blood, and the affected limb needs to be raised for braking. In addition, the paralyzed limb is in a low position for a long time, which will cause limb swelling and the leakage site needs to be raised after fluid extravasation to promote venous return. However, according to the current clinical situation, rehabilitation treatment is not ideal due to the long course of the disease, the high cost of rehabilitation (whether manual or machine-assisted), and the lack of perseverance and patience of patients and their families in exercising. Based on the current situation, it is necessary to invent a simple, practical, and low-cost instrument that can well solve the patient's willingness to exercise independently. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The embodiment of the present application provides a paralyzed limb exercise instrument, which can solve the problems in the related art of high rehabilitation costs and the lack of perseverance and patience of patients in exercising independently.

[0028] See also Figures 1 to 3 The embodiment of the present application provides a paralyzed limb exercise instrument, which includes: a base 1, a connecting tube 2, a manipulation component 4 and a control component. The extending end of the connecting tube 2 is movably connected to the base 1, and a accommodating cavity is provided in the middle of the connecting tube 2; the manipulation component 4 is provided on the base 1, and one end is connected to the connecting tube 2. When the manipulation component 4 is running, the extending end of the connecting tube 2 is driven to flip relative to the base 1; the control component is connected to the manipulation component 4, and is used to control the manipulation component 4 to pause when the extending end of the connecting tube 2 flips to a set angle.

[0029] In the present application, a receiving cavity is provided in the patient's limb, and the operating component 4 is used to drive the connecting tube 2 to flip so that the affected limb can perform passive movements of raising and lowering, which replaces artificial rehabilitation and solves the patient's unwillingness to exercise independently. It can drive the patient to do passive exercise, which is helpful for the patient's rehabilitation. It is simple and practical. When the extended end of the connecting tube 2 flips to a set angle, the operating component 4 is controlled by the control component to suspend operation, so that the patient's affected limb stays at a certain angle and maintains it for a certain time, which can promote the centripetal return of the veins in the affected limb and eliminate swelling. At the same time, it can be used for lifting and braking after limb thrombosis.

[0030] When the device is in use, the limb is inserted into the connecting tube 2 from the insertion end of the connecting tube 2, and then extended from the extension end of the connecting tube 2. During exercise, the operating component 4 drives the extension end of the connecting tube 2 to be raised and lowered, and this is repeated, which helps the patient recover.

[0031] On the basis of the above embodiments, in this embodiment, a button 5 is further provided on the base 1, and the control component includes a notifier, a controller and an angle sensor. The controller, the notifier and the angle sensor are electrically connected, and the button 5 is electrically connected to the operating component 4. The operating component 4 is controlled to run and stop working by the button 5. The notifier includes a notification light, and the angle sensor is connected to the connecting tube 2 for detecting the rotation angle of the connecting tube 2.

[0032] When you want the connecting tube 2 to maintain a certain angle, for example, set the set angle to 30° or 60°. Taking 60° as an example, the operating component 4 drives the connecting tube 2 to rotate. When the angle sensor senses that the connecting tube 2 rotates to 60°, the controller controls the notification light to light up, and controls the operating component 4 to stop working for a set time, for example, stop working for 10 minutes. After 10 minutes, the controller controls the operating component 4 to continue working to drive the connecting tube 2 to rotate; when the connecting tube 2 rotates to 60°, after the operating component 4 stops working, if the patient or medical staff wants the connecting tube 2 to continue rotating, they can press the button 5 to make the operating component 4 continue to work. The paralyzed limbs of patients are prone to swelling, poor venous return, and thrombosis. Keeping the connecting tube 2 at a certain angle can elevate the paralyzed limbs of patients and keep them for a certain period of time to promote venous return and eliminate swelling and thrombosis.

[0033] The control assembly 4 includes: a connecting cable 40 and a reel 42, and the reel 42 is electrically connected to the controller and the button 5. One end of the connecting cable 40 is connected to the extended end of the connecting tube 2; the reel 42 is installed on the base 1, and the other end of the connecting cable 40 passes through a guide 41 and is connected to the reel 42.

[0034] Specifically, a reel 42 and a guide member 41 are respectively disposed on both sides of the base 1, a connecting shaft is fixed on both sides of the extended end of the connecting tube 2, and one end of the connecting cable 40 is connected to the connecting shaft, as shown in FIG. Figure 1As shown, when the connecting tube 2 is placed horizontally, the reel 42 is located between the guide member 41 and the protruding end of the connecting tube 2. More specifically, the reel 42 is located between the guide member 41 and the connecting shaft. The other end of the connecting rope 40 is passed through the guide member 41 and then connected to the reel 42. The guide member 41 guides the connecting rope 40.

[0035] When the extended end of the connecting tube 2 is lifted, the reel 42 reels the connecting rope 40, and the extended end of the connecting tube 2 rotates counterclockwise; when the extended end of the connecting tube 2 is lowered, the reel 42 releases the connecting rope 40, and the extended end of the connecting tube 2 rotates clockwise. The reel 42 can repeatedly lift and lower the extended end of the connecting tube 2 when it is working.

[0036] The rotation center of the connecting tube 2 is located at the insertion end of the connecting tube 2, and the rotation center is on the same horizontal plane as the central axis of the connecting tube 2. A rotating shaft 3 is fixedly connected to the top of the base 1, and one end of the rotating shaft 3 is rotatably connected to the rotation center at the insertion end of the connecting tube 2.

[0037] In addition, in order to facilitate the rotation of the connecting tube 2, a gap is provided between the bottom end of the insertion end of the connecting tube 2 and the top end of the base 1. Furthermore, a through groove 10 is opened on the base 1, and the insertion end of the connecting tube 2 is arranged to be located above the through groove 10. Therefore, when the connecting tube 2 rotates, the base 1 can avoid the insertion end of the connecting tube 2, thereby facilitating the smooth rotation of the connecting tube 2.

[0038] Furthermore, in order to ensure that the connecting tube 2 can be placed horizontally, that is, the central axis of the connecting tube 2 is kept horizontal with the base 1, a sleeve 23 is fixed on the extended end surface of the connecting tube 2, and the sleeve 23 is made of a hard material, and the connecting shaft is fixed on the sleeve 23. In order to ensure that the device is suitable for different patients, the connecting tube 2 is made of a flexible material and has the function of contraction and expansion; therefore, see Figure 3 As shown, the sleeve plate 23 is in a semicircular arc shape, half-wrapping the bottom end of the connecting tube 2, so that it can provide support for the connecting tube 2 without affecting the contraction and expansion functions of the connecting tube 2.

[0039] On the basis of the above embodiment, in this embodiment, the reel 42 includes a motor and a reel, the motor is mounted on the base 1, the motor output shaft is fixed to the reel, and the end of the connecting cable 40 is fixed to the surface of the reel. Therefore, when the motor is working, it drives the reel to rotate, and when the reel rotates counterclockwise, the extended end of the connecting cylinder 2 is lifted up through the connecting cable 40; when the reel rotates clockwise, the extended end of the connecting cylinder 2 is lowered through the connecting cable 40.

[0040] On the basis of the above embodiment, in this embodiment, in order to enable the connection tube 2 to rotate 90°, the height of the guide member 41 is set to be greater than the rotation radius of the connection tube 2; and the guide member 41 is set to be located on one side of the connection tube 2, and the distance between the guide member 41 and the insertion end of the connection tube 2 is smaller than the distance between the guide member 41 and the extension end of the connection tube 2. Through this arrangement, the connection tube 2 can also maintain an upright state, and when the connection tube 2 rotates within 0° to 90°, it can help the patient to raise or lower the patient's limbs.

[0041] This embodiment is a preferred arrangement. In other embodiments, if the connecting tube 2 rotates within a range of 0° to 60°, a guide member 41 may be arranged between the protruding end of the connecting tube 2 and the reel 42 .

[0042] On the basis of the above embodiments, in this embodiment, the guide member 41 includes: a support rod 410, a mounting tube 411 and a roller 412, the support rod 410 is fixed on the base 1; the mounting tube 411 is fixed on the support rod 410; the roller 412 is rotatably connected to the inside of the mounting tube 411, and the surface of the roller 412 is used to contact the connecting rope 40.

[0043] Specifically, the support rod 410 is fixed to the top of the base 1, and a mounting cylinder 411 is fixed to the top of the support rod 410. Two rollers 412 are connected to the mounting cylinder 411 and are rotatable along the height direction of the support rod 410. There is a gap between the two rollers 412 for the connecting rope 40 to pass through. The connecting rope 40 passes between the two rollers 412, and both ends are respectively connected to the winder 42 and the connecting shaft on the connecting cylinder 2.

[0044] On the basis of the above-mentioned embodiment, in this embodiment, the connecting tube 2 comprises a sleeve 20, one end of the sleeve 20 is an inserting end, and the other end is an extending end.

[0045] Specifically, the sleeve 20 is made of a flexible material, and further, the connecting tube 2 further includes a zipper 21 and an elastic band 22. The zipper 21 is arranged on the sleeve 20 along the axial direction of the sleeve 20, and the zipper 21 can be opened to allow the patient's limbs to be placed in the sleeve 20, which is convenient for patients with inconvenient limb movement to use the device; the elastic band 22 is arranged on the sleeve 20 along the circumference of the sleeve 20, and the sleeve 20 can be closely attached to the patient's limbs by adjusting the elastic band 22, so as to prevent the patient's limbs from being separated from the sleeve 20 when the connecting tube 2 is rotated.

[0046] In addition, a heating wire is provided in the sleeve 20, and the button 5 is connected to the heating wire. The heating wire is controlled by the button 5. When the heating wire is working, it can provide a hot compress function to the patient's limbs, which helps the patient's recovery.

[0047] On the basis of the above embodiment, in this embodiment, the paralyzed limb exercise apparatus further includes a massage component, which is arranged on the connecting tube 2. Specifically, the connecting tube 2 includes an air bag, which is installed in the sleeve 20, and the air bag is connected to an external air pump through a ventilation tube. When the patient uses the device, the air pump is operated, and the air bag is inflated and exhausted through the ventilation tube, so that the patient's limbs can be pressurized and massaged to relax the limbs.

[0048] On the basis of the above embodiment, in this embodiment, a limit box is also fixedly connected to the base 1, and a counterweight 6 is clamped in the limit box. When the patient uses the device, the counterweight 6 is placed in the limit box to prevent the base 1 from tilting when the connecting tube 2 rotates.

[0049] In summary, the device can solve the rehabilitation exercise of paralyzed limbs of patients on the one hand, and can solve some common medical problems often encountered in clinical practice on the other hand (such as lifting and braking after deep vein thrombosis, effective lifting to promote venous return after limb swelling, etc.). The device is designed according to the state of human limbs, so that both the upper and lower limbs of patients can be used. The manipulation component 4 is used to work on the connecting tube 2 to drive the limbs to do passive exercise, and can also stay at any slope, so that the limbs stay at the required position, which is helpful for the patient's rehabilitation.
