Technical Field

[0001] The present application relates to the technical field of autologous arteriovenous fistula training equipment, and in particular to an arteriovenous fistula training bracelet. Background Art

[0002] Arteriovenous fistula is a vascular access that directly connects arteries and veins through surgery. It is mainly used for hemodialysis patients to provide sufficient blood flow and stable vascular access. It has the advantages of safety, sufficient blood flow and less chance of infection. Patients need to take daily care of the fistula to prevent complications such as thrombosis and infection to ensure the smooth progress of dialysis treatment.

[0003] In clinical practice, after an arteriovenous fistula surgery, it takes a certain amount of time for the fistula to mature, and the patient needs to take the initiative to exercise. However, many patients are easily affected by the surgical effect due to insufficient exercise. The maturation process will affect the life of the surgeon and is prone to cause some complications.

[0004] Therefore, after the arteriovenous fistula surgery, the patient needs to use his hands to make and release his fists in his daily life to exercise the blood vessels and promote recovery. The exercise process does not force the patient's hands to actively exert force, but the existing exercise equipment for recovery after arteriovenous fistula surgery is basically a handgrip, which requires the patient to actively use force to complete the fist-making and loosening movements, which is easy to reduce the patient's compliance with exercise. Moreover, it is inconvenient to carry with you and is easy to lose, which affects the patient's exercise progress. Summary of the invention

[0034] The invention is further described below by describing embodiments in conjunction with the accompanying drawings.

[0035] This embodiment provides an arteriovenous fistula training bracelet 100, such as Figures 1 to 6 As shown in , in order to solve the above technical problems, the technical solution adopted by the present invention is as follows: comprising a wristband 100 , a finger sleeve 200 , a stretch rope 300 and a driving module 400 .

[0036] In actual use, the bracelet 100 is fixed on the patient's wrist, so that the bracelet 100 can be worn with the patient and is not easy to lose. When exercise is needed, the finger sleeve 200 is fixed on the patient's finger. When exercise is not needed, the finger sleeve 200 is removed from the finger without affecting normal life. One end of the stretch rope 300 is connected to the bracelet 100 and the other end is connected to the finger sleeve 200. The drive module 400 is set in the bracelet 100. The drive module 400 is used to drive the stretch rope 300 to move toward or away from the bracelet 100. Specifically, the stretch rope 300 can be a steel wire, as long as it can push and pull the finger sleeve 200 to move in the axial direction. When exercise is needed, the stretch rope 300 can be driven to retract or retract (change the length of the part outside the bracelet 100) through the driving module 400, thereby controlling the finger sleeve 200 to move toward or away from the bracelet 100, so as to drive the patient's fingers to move toward or away from the wrist, realize the action of clenching and loosening the fist, achieve the effect of passive exercise, and greatly enhance the patient's compliance with exercise.

[0037] In one embodiment, Figures 2 to 6 As shown in , the bracelet 100 includes a main body 110 and a storage slot 111 .

[0038] The main body 110 is used to be mounted and fixed on the patient's wrist. Preferably, the main body 110 is arc-shaped, and its two ends are detachably connected to form a ring to be mounted and fixed on the patient's wrist. The circumference of the main body 110 can be adjusted to match the thickness of the wrist of different patients;

[0039] The storage slot 111 is disposed at one end of the body 110 facing the finger sleeve 200, and is used to store the stretch cord 300. In actual use, when exercising is required, the patient can set and fix the finger sleeve 200 on the patient's finger; when exercising is not required, the patient can remove the finger sleeve 200 from the finger and put the stretch cord 300 and / or the finger sleeve 200 into the storage slot 111 for storage, which does not affect normal life.

[0040] In one embodiment, Figures 1 to 6 As shown in , the stretch rope 300 includes: a limiting sleeve 310 and a rope core 320.

[0041] One end of the limiting sleeve 310 is connected to the main body 110 and the other end faces the finger sleeve 200 . The rope core 320 is slidably arranged in the limiting sleeve 310 . One end of the rope core 320 is connected to the driving module 400 and the other end is connected to the finger sleeve 200 .

[0042] Specifically, the rope core 320 can be a steel wire as long as it can push and pull the finger sleeve 200 in the axial direction. The limiting sleeve 310 mainly guides the direction of the rope core 320, enhances the bending strength of the rope core 320 in the radial direction, and prevents the rope core 320 from excessively bending and affecting the effect of pushing the finger sleeve 200 away from the direction of the bracelet 100.

[0043] In one embodiment, Figures 4 to 6 As shown in FIG. 4 , the driving module 400 includes a winding shaft 410 and a driving unit.

[0044] One end of the rope core 320 away from the finger sleeve 200 is connected to the winding shaft 410 , and the rope core 320 is wound on the winding shaft 410 ; the winding shaft 410 is driven by the driving unit to rotate to drive the rope core 320 to move toward or away from the bracelet 100 .

[0045] Specifically, part of the rope core 320 passes through the outside of the bracelet 100, and the other part is located inside the bracelet 100 and is wound around the winding shaft 410. The driving unit drives the winding shaft 410 to rotate, so that the length of the rope core 320 wound around the winding shaft 410 can be increased or decreased, thereby controlling the increase or decrease of the length of the part of the rope core 320 passing through the outside of the bracelet 100, and then controlling the sleeve to move toward or away from the bracelet 100, so as to drive the patient's fingers to move toward or away from the wrist, realize the action of making and loosening the fist, and achieve the effect of passive exercise.

[0046] In one embodiment, Figure 5 to Figure 6 As shown in the figure, the driving module 400 also includes: a screw assembly 420, the screw assembly 420 is connected to the winding shaft 410, the screw assembly 420 is driven by the driving unit to rotate to drive the winding shaft 410 to rotate, and the winding shaft 410 is driven by the screw assembly 420 to move at a uniform speed along the axial direction of the winding shaft 410.

[0047] Specifically, the driving module 400 is a motor, and the motor, the screw assembly 420 and the winding shaft 410 are all coaxially arranged. There is a cavity in the bracelet 100, and the motor, the screw assembly 420 and the winding shaft 410 are all arranged in the cavity, and a threaded block meshing with the screw assembly 420 is arranged in the cavity. When the winding shaft 410 rotates to wind or loosen the rope core 320, the screw assembly 420 drives the winding shaft 410 to move along its axial direction, so that the rope core 320 wound on the screw assembly 420 is wound on the winding shaft 410 in a spiral manner. Since the rope core 320 is evenly wound on the winding shaft 410, the rope core 320 is avoided from being continuously wound on the same position on the winding shaft 410, the correlation between the number of rotations of the winding shaft 410 and the moving distance of the finger sleeve 200 is improved, and the situation in which the finger sleeve 200 excessively moves toward or away from the bracelet 100 during use by the patient is avoided, thereby improving safety.

[0048] In one embodiment, Figure 5 to Figure 6 As shown in , the driving module 400 also includes: a plurality of guide wheels 430 , which are rotatably disposed in the bracelet 100 , and the plurality of guide wheels 430 are disposed around the rope core 320 , and the rope core 320 is in contact with the plurality of guide wheels 430 .

[0049] Specifically, the middle part of the side surface of the guide wheel 430 in the axial direction is concave toward the axial direction, so that the contact area between the guide wheel 430 and the rope core 320 is increased, and the limiting effect of the guide wheel 430 on the rope core 320 is improved. Preferably, three guide wheels 430 are provided, and the angle between every two guide wheels 430 is 120°.

[0050] In one embodiment, the limiting sleeve 310 is bendable in the radial direction.

[0051] During actual use, due to the different shapes of patients' hands, the limiting sleeve 310 can be bent radially to make it fit the shape of the patient's hand better, better drive the patient's fingers to move toward or away from the wrist, realize the action of clenching and loosening the fist, and achieve the effect of passive exercise.

[0052] In one embodiment, a plurality of stretch ropes 300 are provided, and a plurality of limiting sleeves 310 are detachably provided on the main body 110 .

[0053] Specifically, by providing multiple stretching ropes 300, multiple fingers can be driven to complete the action of clenching and loosening fists. Preferably, in order to reduce costs, multiple stretching ropes 300 can be connected in parallel, and multiple stretching ropes 300 can be driven to move by one driving unit. Preferably, the rope cores 320 of the multiple stretching ropes 300 are connected to each other at one end facing the bracelet 100.

[0054] In one embodiment, Figure 4 As shown in , the bracelet 100 further includes: a clamping block 120 , which is disposed at an opening edge of the storage slot 111 , and the clamping block 120 is used to restrict the stretching rope 300 in the storage slot 111 from leaving the storage slot 111 .

[0055] In one embodiment, Figures 2 to 4 As shown in , the wristband 100 further includes a heart rate sensor 130. The heart rate sensor 130 is disposed on the surface of the wristband 100 facing the patient's wrist, and the heart rate sensor 130 is used to monitor the patient's heart rate.

[0056] Preferably, the wristband 100 can be provided with a variety of sensors, positioning modules, communication modules, etc. for monitoring the patient's physical condition.

[0057] In summary, the present application relates to the technical field of autologous arteriovenous fistula training equipment, and discloses an arteriovenous fistula training bracelet, which includes a bracelet, a finger sleeve, a stretch rope, and a drive module. The bracelet is used to be mounted and fixed on the patient's wrist, the finger sleeve is used to be mounted and fixed on the patient's finger, one end of the stretch rope is connected to the bracelet, and the other end is connected to the finger sleeve. The drive module is arranged in the bracelet, and the drive module is used to drive the stretch rope to move toward or away from the bracelet. The present invention can push and pull the fingers toward or away from the wrist by setting the finger sleeve, through the stretch rope and the drive module, so as to help the patient to achieve the action of clenching and loosening the fist, so as to achieve the effect of passive exercise, and greatly enhance the patient's compliance with exercise; and a bracelet that can be worn on the wrist is provided, and the equipment can be carried with you for exercise at any time, and is not easy to lose, which can promote the patient's exercise progress.
