Description

Technical Field

[0001] The utility model relates to the technical field of exercise equipment, in particular to an exercise device after internal fistula surgery. Background Art

[0002] Arteriovenous fistula is called the lifeline of dialysis patients. Autologous arteriovenous fistula formation is a surgical procedure that anastomoses the patient's peripheral arteries and superficial veins, allowing arterial blood to flow to the superficial veins, making it easier to meet the dialysis blood flow requirements and facilitating vascular puncture to establish extracorporeal circulation. In order to promote the rapid maturation of the fistula, usually within 1 week after the operation, when the wound is free of infection, bleeding, and healing well, the intensity of exercise is gradually increased, from pinching the fingers to clenching the fist and then to holding a rubber grip ring. During exercise, a compression cuff is generally used to press the upper part of the upper limb on the arteriovenous fistula side to moderately expand and fill the arteriovenous fistula blood vessels. At the same time, an empty fist or a gripping machine is used. The compression cuff cannot be pressed on the upper limb all the time, otherwise there is a risk of fistula occlusion, and the pressure must be released in a cycle.

[0003] In the actual operation, others are needed to help tighten and loosen the compression cuff, which is troublesome. If the operation is improper, the vein will not return for a long time, which may cause the risk of internal fistula occlusion. Therefore, a training device that can press the upper arm with hand grasping is needed. However, due to the different hand strengths of different users, if the hand strength of the user is too strong, it will cause discomfort to the upper arm. Utility Model Content

[0034] Preferably, a connecting arc plate 404 is provided at the bottom of the pressing ring 403, and the bottom of the connecting arc plate 404 is connected to the pull rope 505. A pulley 506 is provided at the top of the pull rope 505. The slide rod 502 drives the pull rope 505 to move, and the pull rope 505 applies tension to the connecting arc plate 404. The connecting arc plate 404 is pulled downward by the pull rope 505, and the connecting arc plate 404 drives the pressing ring 403 to press down, exerting pressure on the user's arm.

[0035] Usage process: When the user makes a gripping action to drive the movable handle 301 to move toward the fixed handle 201, the movable handle 301 drives the slider member 501 to move, which drives the slide bar 502 to slide toward the fixed handle 201, and the slide bar 502 drives the pull rope 505 to move, and the pull rope 505 applies tension to the connecting arc plate 404, and the connecting arc plate 404 is pulled downward by the pull rope 505, and the connecting arc plate 404 drives the pressing ring 403 to press downward, exerting pressure on the user's arm;

[0036] When the user relaxes his fingers, the movable handle 301 is reset, which drives the slider member 501 to move away from the fixed handle 201 and reset together. At this time, the slider member 501 does not slide with the slide bar 502, and the slide bar 502 is reset under the action of the second elastic member 503.

[0037] Example 3, reference Figure 1 to Figure 5 , which is the second embodiment of the utility model. Different from the previous embodiment, the slider member 501 includes a sliding shell 501a, the side of the sliding shell 501a is arranged on the inner wall of the square groove 204, and the sliding shell 501a can slide in the square groove 204.

[0038] Furthermore, the inner wall of the sliding shell 501a is provided with accommodating holes 501b on both sides, the accommodating holes 501b are provided with clamping blocks 501c inside, the sides of the clamping blocks 501c are provided with third elastic members 501d, and the bottom of the clamping blocks 501c is provided with clamping grooves 501e for clamping the sliding rod 502. When the user performs a gripping action to drive the movable handle 301 to move toward the fixed handle 201, the clamping blocks 501c apply pressure to the sliding rod 502 using the clamping grooves 501e under the action of the third elastic member 501d, and the friction force generated by the pressure on the sliding rod 502 drives the sliding rod 502 to slide, and the sliding rod 502 is driven by the friction force generated by the pressure. The rod 502 drives the pull rope 505 to move, and the pull rope 505 applies tension to the connecting arc plate 404. The connecting arc plate 404 is pulled downward by the pull rope 505, and the connecting arc plate 404 drives the pressing ring 403 to press down, exerting pressure on the user's arm. If the user uses too much hand strength, the dynamic handle 301 drives the sliding shell 501a to slide, and the pressure transmitted to the sliding shell 501a by the dynamic handle 301 is greater than the maximum friction force that can be generated by the clamping groove 501e and the sliding rod 502. The clamping groove 501e and the sliding rod 502 will slip, so the excessive force will not be transmitted to the pressing component 400, so as to prevent discomfort to the user's arm.

[0039] Preferably, a spherical groove 501f is provided on the top of the clamp block 501c, a top ball 501g is provided on the side of the spherical groove 501f, a transmission plate 501h is provided on the side of the top ball 501g, a fourth elastic member 501i is provided on the side of the transmission plate 501h, and one end of the fourth elastic member 501i away from the transmission plate 501h is provided on the inner wall of the sliding shell 501a. The user drives the movable handle 301 to move toward the fixed handle 201 by grasping, and the movable handle 301 uses the protrusion 302 to press the transmission plate 501h toward the fixed handle 201, driving the top ball 501g away from the top of the clamp block 501c. Spherical groove 501f, at this time, the clamp block 501c will use the clamp groove 501e to clamp the sliding bar 502, when the user's fingers relax, the movable handle 301 will move away from the fixed handle 201 and reset, at this time, the protrusion 302 at the bottom of the fixed handle 201 will move away from the transmission plate 501h, and the transmission plate 501h will move toward the clamp block 501c under the action of the fourth elastic member 501i, and the top ball 501g on the side of the transmission plate 501h will direct the spherical groove 501f on the top of the clamp block 501c to separate the clamp block 501c, at this time, the clamp block 501c will not clamp the sliding bar 502, and the sliding bar 502 will automatically reset under the action of the third elastic member 501d.

[0040] Usage process: the user makes a grasping action to drive the movable handle 301 to move toward the fixed handle 201, and the clamping block 501c uses the clamping groove 501e to apply pressure to the sliding rod 502 under the action of the third elastic member 501d, and uses the friction force generated by the pressure on the sliding rod 502 to drive the sliding rod 502 to slide, and the sliding rod 502 drives the pull rope 505 to move, and the pull rope 505 applies tension to the connecting arc plate 404, and the connecting arc plate 404 is pulled downward by the pull rope 505, and the connecting arc plate 404 drives the pressing ring 403 to press down, applying pressure to the user's arm. If the user uses too much hand strength, the movable handle 301 drives the sliding shell 501a to slide, and the pressure transmitted to the sliding shell 501a by the movable handle 301 is greater than the maximum friction force that can be generated by the clamping groove 501e and the sliding rod 502, and the clamping groove 501e and the sliding rod 502 will slip, so the excessive force will not be transmitted to the pressing component 400, so as to prevent discomfort to the user's arm.
