Description

Technical Field

[0001] The utility model relates to the technical field of postoperative exercise tools, in particular to an exercise device for assisting internal fistula maturation. Background Art

[0002] Exercisers that assist in the maturation of fistulas usually refer to tools or equipment that help patients with arteriovenous fistulas (AVFs) to perform postoperative exercises to promote the maturation of fistulas and improve their quality of use. The main purpose of these exercisers is to stimulate the blood vessels after surgery, increase blood flow, prevent thrombosis, and ensure that the fistula vessels are mature and stable enough to meet the needs of hemodialysis.

[0003] Currently, the most common exercise tools are grip balls and hand grippers. Today's grip balls are usually hollow rubber balls. When patients exercise, they hold the grip balls in their hands and repeatedly clench and relax the grip balls. This can increase the blood flow in the veins and help the maturation of the fistula. However, in actual situations, the grip strength of patients varies due to differences in age, physical fitness, severity of the disease, etc. The grip strength of patients is also different at different stages of recovery. Using grip balls cannot adapt to the corresponding recovery stage, resulting in poor exercise results. Utility Model Content

[0018] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model proposes an exerciser for assisting the maturation of internal fistula, comprising a rubber ring 1, an inner wall of one side of the rubber ring 1 is provided with an installation groove, a support plate 2 is fixedly installed in the installation groove, four telescopic components are fixedly installed on the support plate 2, and the telescopic components include a telescopic tube 3 and a telescopic rod 4; one end of the telescopic tube 3 is fixedly installed on the support plate 2, and an end of the telescopic tube 3 away from the support plate 2 is provided with a telescopic hole that is slidably matched with the telescopic rod 4, and the end of the telescopic rod 4 is fixedly connected to the inner wall of the other side of the support plate 2, and a pressure regulating structure is installed on the telescopic component, and the pressure regulating structure is used to adjust the force of the output shaft of the telescopic component to extend. The size of the output shaft end of the telescopic component is fixedly connected to the inner wall of the other side of the rubber ring 1. In actual operation, the patient grasps the rubber ring 1, and the four fingers except the thumb grasp the outer periphery of the rubber ring 1. The patient or medical staff adjusts the pressure to suit the patient's exercise through the pressure adjustment structure according to the patient's actual situation. Since there are four telescopic components, they can be adjusted separately according to the situation of each finger. When the four fingers are bent, the four fingers respectively rest on the output shaft ends of the four telescopic components for exercise, thereby ensuring that it can be adjusted to adapt to the patient's condition, recovery condition, etc., so that the exercise effect is better.

[0019] The pressure regulating structure includes an adjusting block 5, a spring 6 and an adjusting assembly; the adjusting block 5 is slidably installed in the telescopic hole, and the two ends of the spring 6 are respectively against the end of the telescopic rod 4 and the adjusting block 5; the adjusting assembly is used to adjust the position of the adjusting block 5 in the telescopic hole, and the adjusting assembly includes a limit slider 7, a semi-threaded rod 8, a first bevel gear 9, a second bevel gear 10 and an adjusting rod 11; a movable hole that is slidably matched with the limit slider 7 is opened in the telescopic rod 4, one end of the semi-threaded rod 8 is rotatably connected to the limit slider 7, the semi-threaded rod 8 threads through the adjusting block 5, and the other end of the semi-threaded rod 8 is rotatably installed on the inner wall of the end of the telescopic hole, the first bevel gear 9 is fixedly connected to the other end of the semi-threaded rod 8, a rotating groove that is rotatably matched with the first bevel gear 9 is opened in the telescopic cylinder 3, the second bevel gear 10 is rotatably installed in the telescopic cylinder 3, and the second bevel gear 10 is meshed with the first bevel gear 9, and one end of the adjusting rod 11 It runs through one side of the telescopic cylinder 3 and is fixedly connected with the No. 2 bevel gear 10. In actual conditions, the hexagonal handle can be inserted into the hexagonal groove at the end of the adjusting rod 11, and the adjusting rod 11 is rotated. The adjusting rod 11 drives the No. 2 bevel gear 10 to rotate, and the No. 2 bevel gear 10 drives the No. 1 bevel gear 9 to rotate. The rotating No. 1 bevel gear 9 drives the semi-threaded rod 8 to rotate. Since the semi-threaded rod 8 is threadedly matched with the adjusting block 5, the adjusting block 5 can only slide in the telescopic hole. Since the semi-threaded rod 8 cannot be displaced, the adjusting block 5 slides in the telescopic hole. When the adjusting block 5 slides, the compression of the spring 6 can be controlled. As the compression of the spring 6 changes, the reaction force generated by the spring 6 will also change accordingly, thereby controlling the rebound force of the spring 6 on the telescopic rod 4 and adjusting the strength required when the fingers are gripped. The adjustment is simple and convenient to adjust according to actual needs, which is convenient for patients to recover from exercise.

[0020] Four placement grooves are provided on the inner wall on the other side of the rubber ring 1, and finger pressure plates 12 are fixedly installed in the placement grooves. The four finger pressure plates 12 are fixedly connected to the ends of the four telescopic rods 4 respectively. When the patient is exercising, the contact area between the patient's fingers and the ends of the telescopic rods 4 is increased, thereby increasing the comfort of the fingers when gripping. In addition, the finger pressure plate 12 can be designed to be semicircular or arc-shaped, with the convex surface facing the fingers, to increase comfort.

[0021] An open groove is provided on the outer periphery of one side of the rubber ring 1 close to the acupressure plate 12, and an airbag 13 is fixedly installed in the open groove. The connection state between the four acupressure plates 12 can be controlled by controlling the inflation degree in the airbag 13. When the airbag 13 is full of air, the four acupressure plates 12 and the airbag 13 can be regarded as one piece. When the airbag 13 is deflated, during exercise, four fingers are respectively held on the four acupressure plates 12, thereby reducing the connection between the four acupressure plates 12, making it convenient for the four fingers to exercise separately and ensuring the exercise effect.
