Description

Technical Field

[0001] This utility model relates to the field of medical exercise equipment technology, and in particular to a grip strength training device for arteriovenous fistula surgery. Background Technology

[0002] Arteriovenous fistulas (AVFs) are the most common vascular access for maintenance hemodialysis patients, providing an adequate blood supply and ensuring the adequacy of dialysis treatment. Therefore, AVF surgery is frequently performed on many patients requiring hemodialysis. Autogenous AVF creation requires 4-12 weeks to mature. Effective functional exercises can promote maturation; currently, the most widely used and patient-accepted functional exercise is grip strength training.

[0003] Grip strength is influenced by individual differences, such as age, gender, and health status. Different individuals also experience and respond differently to grip strength training, making it difficult to establish a unified standard for quantifying strength. Furthermore, training too quickly or too slowly results in insignificant improvements in blood flow and vessel diameter, especially for elderly patients with hearing or visual impairments, who may lack sufficient functional training, leading to insufficient blood flow for hemodialysis due to the arteriovenous fistula. Therefore, this paper proposes a grip strength training device for arteriovenous fistula surgery to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a grip strength training device for arteriovenous fistula surgery. It aims to improve the existing technology where grip strength is affected by individual differences, making it difficult to establish a unified standard for quantifying strength. Furthermore, excessively fast or slow frequency can lead to insignificant improvement in blood flow and vascular diameter, resulting in arteriovenous fistulas being unable to meet the blood flow requirements for hemodialysis.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grip strength training device for arteriovenous fistula surgery, comprising a grip ball, a display screen fixedly connected to the end face of the grip ball, a fixing plate fixedly connected to the inner wall of the grip ball, an elastic component disposed inside the grip ball, the elastic component comprising a crescent plate, the crescent plate being fixedly connected to the inner wall of the grip ball, two sets of symmetrically arranged pressure springs fixedly connected to the bottom surface of the crescent plate, a support plate fixedly connected to the bottom end of the pressure springs, and a pressure sensor fixedly connected to the bottom surface of the support plate.

[0006] As a further description of the above technical solution:

[0007] The pressure sensor has a grip force adjustment component at its bottom. The grip force adjustment component includes a bidirectional threaded rod. One end of the bidirectional threaded rod is rotatably connected to the side wall of the fixed plate, and the other end of the bidirectional threaded rod is fixedly connected to a brake wheel. The bidirectional threaded rod passes through and is rotatably connected to the end of the grip ball.

[0008] As a further description of the above technical solution:

[0009] A counter is fixedly connected to the surface of the support plate, and a contact is fixedly connected to the bottom surface of the crescent plate. The counter is connected to the display via a signal.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the bidirectional threaded rod is threaded with two sets of symmetrically arranged threaded sleeves. A support rod is hinged to the surface of the threaded sleeve, and the top end of the support rod is hinged to the bottom surface of the pressure sensor.

[0012] As a further description of the above technical solution:

[0013] The crescent-shaped plates are provided in multiple sets, and the array of multiple sets of crescent-shaped plates is distributed on the inner wall of the grip ball.

[0014] As a further description of the above technical solution:

[0015] A voice broadcast module is fixedly connected to the bottom surface of the pressure sensor, and both the voice broadcast module and the pressure sensor are connected to the display via signals.

[0016] As a further description of the above technical solution:

[0017] The grip ball is elliptical in shape and has a rubber surface.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by rotating the bidirectional threaded rod in the forward or reverse direction, the two sets of threaded sleeves move towards each other or away from each other, thereby changing the tilt angle of the support rod, causing the position of the pressure sensor to move upward or downward, and thus adjusting the compression degree of the pressure spring, thereby adjusting the training resistance to meet the training needs of different patients.

[0020] 2. In this utility model, a pressure sensor is installed at the bottom of the support plate to monitor the pressure and force during grip strength training. The data is fed back to the display, and a voice broadcast module can provide real-time audio prompts to help users adjust the intensity of grip strength.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1-2 This utility model provides an embodiment of a grip strength training device for arteriovenous fistula surgery, comprising a grip ball 1. The grip ball 1 is elliptical in shape and has a rubber surface. The elliptical design and rubber material of the grip ball 1 provide a comfortable gripping experience for the user. A display 11 is fixedly connected to the end face of the grip ball 1. The display 11 is used to display relevant data during the training process, such as grip strength and training time, to help the patient understand the training effect. A fixing plate 2 is fixedly connected to the inner wall of the grip ball 1.

[0029] Reference Figure 2-3The grip ball 1 has an internal elastic component 3, which is used in conjunction with the grip strength adjustment component 4 to provide the resistance required during grip strength training. The elastic component 3 includes a crescent plate 31, which is fixedly connected to the inner wall of the grip ball 1. Multiple sets of crescent plates 31 are arranged in an array on the inner wall of the grip ball 1. Two sets of symmetrically arranged pressure springs 32 are fixedly connected to the bottom surface of the crescent plate 31. A support plate 33 is fixedly connected to the bottom end of the pressure springs 32. The pressure springs 32 are used to provide elastic support for the crescent plate 31 and provide resistance for grip strength training. A counter 34 is fixedly connected to the surface of the support plate 33. A contact point 35 is fixedly connected to the bottom surface of the crescent plate 31. The counter 34 is connected to the display 11 via a signal. When gripping the grip ball 1, the crescent plate 31 is subjected to pressure, which compresses the pressure springs 32. The contact point 35 on the bottom surface of the crescent plate 31 contacts the counter 34, thereby triggering a reading. The reading is then fed back to the display 11 via a transmission signal. A pressure sensor 36 is fixedly connected to the bottom surface of the support plate 33, and a voice broadcast module 37 is fixedly connected to the bottom surface of the pressure sensor 36. Both the voice broadcast module 37 and the pressure sensor 36 are connected to the display 11 via signals. The pressure sensor 36 is used to monitor the pressure and force during grip strength training and feeds the data back to the display 11 for the user to view. The voice broadcast module 37 then broadcasts the displayed data.

[0030] Reference Figure 2 , Figure 4 A grip strength adjustment component 4 is provided at the bottom of the pressure sensor 36. The grip strength adjustment component 4 is used to adjust the resistance level of the grip ball 1 to meet the training needs of different patients. The grip strength adjustment component 4 includes a bidirectional threaded rod 41. One end of the bidirectional threaded rod 41 is rotatably connected to the side wall of the fixed plate 2, and the other end of the bidirectional threaded rod 41 is fixedly connected to a brake wheel 42. The brake wheel 42 facilitates the user to rotate the bidirectional threaded rod 41. The bidirectional threaded rod 41 passes through and is rotatably connected to the end of the grip ball 1. Two sets of symmetrically arranged threaded sleeves 43 are threadedly connected to the outer wall of the bidirectional threaded rod 41. A support rod 44 is hinged to the surface of the threaded sleeve 43. The top end of the support rod 44 is hinged to the bottom surface of the pressure sensor 36. By rotating the bidirectional threaded rod 41 in the forward or reverse direction, the two sets of threaded sleeves 43 move towards each other or away from each other, thereby changing the tilt angle of the support rod 44, causing the position of the pressure sensor 36 to move upward or downward, thereby adjusting the compression degree of the pressure spring 32, achieving the effect of adjusting the training resistance to meet the training needs of different patients.

[0031] Working principle: Patients use the grip ball 1 for grip strength training. The oval shape and rubber material design provide a comfortable grip. The pressure spring 32 inside the grip ball 1 provides resistance. Patients perform grip strength training by gripping the ball and squeezing it. When gripping the grip ball 1, the crescent plate 31 is affected by pressure, which compresses the pressure spring 32. The contact point 35 on the bottom surface of the crescent plate 31 contacts the counter 34, thereby triggering the reading. The reading is then fed back to the display 11 through the transmission signal to show the corresponding reading.

[0032] By rotating the bidirectional threaded rod 41 in the forward or reverse direction, the two sets of threaded sleeves 43 move towards each other or away from each other, thereby changing the tilt angle of the support rod 44, causing the pressure sensor 36 to move up or down, and thus adjusting the compression degree of the pressure spring 32, thereby adjusting the training resistance to meet the training needs of different patients.

[0033] The pressure sensor 36 monitors the strength and pressure of the grip and feeds this data back to the display 11. The voice broadcast module 37 can also provide real-time audio prompts to help users adjust the strength of their grip.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
