Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a multi-dimensional autologous arteriovenous fistula function exerciser and a method for using the same. Background Art

[0002] Autologous arteriovenous fistula (AVF) is the "lifeline of hemodialysis patients", the most ideal vascular access, and the premise and guarantee for hemodialysis. However, its service life is not permanent, and it is also prone to complications such as infection, vascular stenosis, thrombosis or embolism, venous hypertension, aneurysm, high-output heart failure, and access-related ischemic syndrome, which lead to fistula failure. Vascular access dysfunction is an important cause of death in hemodialysis patients. Studies have shown that about 4.8% of patients who use AVF for hemodialysis die within the first 3 months; about 11% of patients die within the first 1 year. 39.8% of autologous arteriovenous fistulas may have complications, and the hospitalization rate caused by them is about 9.8%. 20%-25% of dialysis patients are hospitalized due to AVF failure. How to maintain AVF, how to conduct scientific and effective functional exercises to keep it in good functional state and high patency, extend its service life, reduce AVF dysfunction, improve the effect of hemodialysis treatment, and improve the quality of life of patients are currently urgent problems to be solved. Therefore, it is very important to provide a personalized, continuous, safe and stable functional exercise equipment and exercise methods.

[0003] At present, the commonly used exercise methods and existing patents in clinical practice mainly include squeezing rubber balls or rubber bands and simply binding arms. These methods have the following disadvantages:

[0004] Limitations of hand problems, difficult to standardize and personalize: Different patients have different hand strength and motor abilities, making it difficult to standardize the intensity of exercise. For example, elderly patients or patients with hand disabilities may not be able to squeeze a ball as effectively as young healthy patients, resulting in insufficient filling of the arteriovenous fistula.

[0005] The process cannot be monitored, making it difficult to ensure its effectiveness: key indicators such as blood flow and vascular pressure cannot be accurately monitored during the process, making it impossible to determine whether the exercise has achieved an effective level in promoting the maturation of the fistula and maintaining its function.

[0006] Problems with arm-binding exercises: Arm-binding exercises affect blood flow by applying external pressure to the upper limbs, but they also have obvious shortcomings. It is difficult to standardize the tightness of the arm-binding exercise. If it is too loose, it will not achieve effective exercise results and the internal fistula will not be filled enough; if it is too tight, it may affect blood circulation in the upper limbs and even damage the blood vessels. Moreover, it is also impossible to quantify the intensity and effect of the exercise during the exercise, and it is unknown whether it is really beneficial to the improvement of the internal fistula function.

[0007] The exercise method is single: simply squeezing a rubber ball or rubber band with the hands, simply tying the arms or making a fist. The exercise method is single and effective for the functional exercise of internal fistula. However, some patients suffer from tenosynovitis or finger joint injuries due to incorrect force application method.

[0008] The existing basic solution has made up for the above defects to a certain extent, but there are also certain problems: the basic solution combines a variety of exercise methods, combining the traditional ball squeezing exercise and arm binding exercise, and designs a device that can achieve both exercise effects at the same time, so that muscle exercise and blood vessel expansion can be carried out at the same time to achieve a better filling effect. The inflatable cuff is inflated by squeezing the balloon, which applies pressure to the upper limbs. At the same time, the squeezing of the balloon also exercises the hand muscles and promotes blood circulation. However, it also has certain problems:

[0009] Problems with coordination: Performing both the squeezing of the ball and the arm restraint requires coordination and hand dexterity. The patient may be too focused on the squeezing of the ball and ignore the pressure control of the arm restraint.

[0010] Distraction: Performing two exercises at the same time requires the patient to concentrate to coordinate the movements of various parts of the body, which may make the patient feel nervous and easily fatigued during the exercise. Distraction may also cause the patient to be unable to fully feel the body's feedback during the exercise, such as the fullness of the fistula site and the comfort of the arm, making it difficult for the patient to adjust the intensity and method of exercise in time according to their own situation.

[0011] Pressure control problem: Double pressure superposition risk. The ball squeezing exercise itself will cause the upper limb muscles to contract and increase the pressure on the upper limb blood vessels, while the arm binding exercise will further restrict the blood return of the upper limbs through external pressure, prompting blood to flow to the fistula. If the two pressures are not properly controlled, it may cause excessive pressure at the fistula site, increasing the risk of fistula blood vessel damage.

[0012] Adaptation problem: The basic solution ignores the stability and comfort of the inflatable cuff under different pressures. Each patient has different grip strength, and even for the same patient, the stability of pressure cannot be guaranteed; and arm binding is a squeezing process, so increasing the comfort of the cuff can increase patient compliance.

[0013] The problem of cuff individualization: The upper limb size, shape, fistula location, etc. of different patients are different, so the exercise device also needs to pay attention to the individualization of patients.

[0014] Patient compliance issues: Single ball squeezing or arm binding exercises are boring, and the combination of the two does not significantly improve the fun of exercise. Patients tend to get bored when repeating the same combination of movements for a long time, and it is difficult for them to persist in exercising at the prescribed frequency and intensity. This requires adding some incentive mechanisms or diversified exercise elements to the exercise process to improve patients' interest and compliance.

[0015] In order to solve the above problems, the present invention provides a multi-dimensional autologous arteriovenous fistula function exerciser and a method of using the same to solve the problem that the previous exercise devices have single functions and poor adaptability to the human body.
