Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for training the function of internal fistula. Background Art

[0002] Chronic kidney disease is a global public health problem, with a prevalence rate as high as 14.3%. When chronic kidney disease develops to the end stage, more than 80% of patients rely on maintenance hemodialysis treatment to prolong their lives. Effective vascular access is the key to smooth hemodialysis treatment. Autologous arteriovenous fistula is the preferred type of vascular access due to fewer complications, but its 5-year survival rate is only 50.5%. Studies have shown that perioperative functional exercise of AVF can promote its maturation, but it cannot achieve a satisfactory service life in the long term. Related studies have pointed out that good arteriovenous conditions are an important prerequisite for establishing an ideal AVF. Functional exercise can promote the early maturation of AVF and prolong its use time. Perioperative vascular function exercise is particularly important for patients with poor vascular conditions such as the elderly and those with diabetes. At present, the commonly used functional exercise method at home and abroad is grip strength exercise, which can effectively improve the inner diameter and blood flow of the fistula blood vessels, which is conducive to the establishment and maturation of AVF.

[0003] In order to promote the maturation of the fistula, the patient can make a fist or hold a ball with his hands after the arteriovenous fistula surgery. However, a single fist or ball holding exercise can only exercise the palm and the area near the palm. The grip strength of different patients is obviously different (the grip strength of the elderly and children is smaller, and the grip strength of young people is larger). The use of a single grip training device is difficult to apply to the majority of people, making it difficult for some patients to find the right grip feeling for their own grip in a single grip training device, resulting in insufficient grasping or weak grasping force, and ultimately resulting in less impact on the fistula area. This method often affects the maturation of the fistula due to insufficient attention to the functional exercise of the fistula. In severe cases, it will lead to the failure of the fistula formation surgery, and it is difficult to exercise the arm area together. The most ideal fistula exercise method is to allow blood to fill the blood vessels every time you grip, so that the fistula gradually expands and gets effective exercise. That is, when the palm is grasping, if there is an instrument to hold the arm with the same force at the same time, the blood vessels in the arm can be filled, thereby effectively exercising the fistula.

[0004] Therefore, it is necessary to propose a fistula function training device to adjust the appropriate gripping strength of the trainer, and at the same time to cooperate with the gripping strength of the patient to clench the arm, so as to achieve effective fistula training.

[0031] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1-Figure 5 The utility model proposes a fistula function training device, comprising a breathable glove 1, an inflatable soft gripping ball 2, an inflatable arm clamping ring 3, and a main controller 4. The main controller 4 is provided with a display screen and a plurality of buttons. The patient can adjust the inflation amount of the inflatable soft gripping ball 2 by pressing the buttons, and the display screen can view the parameters of the gripping force. The inflatable soft gripping ball 2 is made of a soft and elastic material. After being inflated, it will produce an adaptive deformation when gripping. The gripping force is different according to the different inflation amounts. The inflatable soft gripping ball 2 forms a palm part with the breathable glove 1. The connection is detachable, and a first inflation and deflation device 41 and a second inflation and deflation device 42 are provided on the main controller 4. Both the first inflation and deflation device 41 and the second inflation and deflation device 42 are electrically connected to the main controller 4. The inflatable soft grasping ball 2 is connected and conducted to the first inflation and deflation device 41 through a hose, and the inflatable arm clamping ring 3 is connected and conducted to the second inflation and deflation device 42 through a hose. The main controller 4 can control the inflation amount of the inflatable arm clamping ring 3 according to the change of air pressure formed by the force of grasping the inflatable soft grasping ball 2, thereby performing internal fistula function training.

[0033] In this embodiment, before performing fistula training, the inflatable soft gripping ball 2 can be fixed on the palm of the breathable glove 1, so that the inflatable soft gripping ball 2 will not fall off when relaxing. The breathable glove 1 can be used on both sides to exercise the patient's left hand or right hand. After the breathable glove 1 fixes the inflatable soft gripping ball 2, the patient can put on the glove to grip the inflatable soft gripping ball 2. The inflatable soft gripping ball 2 can be inflated to a suitable amount by controlling the first inflation and deflation device 41 of the main controller 1 to achieve different gripping effects, which is suitable for use by a wide range of groups. At the same time, the main controller 1 can also control the second inflation and deflation device 42 to supply air to the inflatable arm clamping ring 3. Every time the patient grips the inflatable soft gripping ball 2, the inflatable arm clamping ring 3 can grip the patient's arm with the same force, so that the blood vessels in the arm are closed and congested, so as to achieve full exercise of the fistula.

[0034] In summary, the fistula function training device can adjust the appropriate gripping strength of the trainer to facilitate its applicability to a wide range of groups, and can also clench the arm in accordance with the gripping strength of the patient to effectively train the fistula.

The first air supply pump 411, the first air release valve 412, and the air pressure sensor 413 are all electrically connected to the main controller 4 through internal conductive wires. The first air supply pump 411 is used to inflate the inflatable soft grasping ball 2, and the first air release valve 412 is used to deflate when the patient is not using the utility model or adjusting the air pressure in the inflatable soft grasping ball 2. The sensor 413 is used to obtain the air pressure change value in the inflatable soft gripping ball 2. One end of the air pressure sensor 413 is connected to and conducted with the first air supply pump 411, and the other end of the air pressure sensor 413 is connected to and conducted with the inflatable soft gripping ball 2 through a hose. The first air release valve 412 is connected to and conducted with the inflatable soft gripping ball 2 through a hose. After the inflatable soft gripping ball 2 is properly inflated, the main controller 1 calibrates the current value of the air pressure sensor 413 and records it as the air pressure when no gripping is performed. When the patient performs fistula exercise, the gas inside the inflatable soft grasping ball 2 will be compressed when it is grasped, which will cause the air pressure to rise. The changed air pressure value sensed by the air pressure sensor 413 is transmitted back to the main controller 1, and the main controller 1 issues a corresponding air supply instruction to the second inflation and deflation device 42 according to the changed air pressure value, so as to supply air to the inflatable arm clamping ring 3 under the same air pressure change value, so that the inflatable arm clamping ring 3 can grip the patient's arm with the same force. , so that internal fistula exercise can be effectively performed; an air inlet connection port 21 is provided on the inflatable soft gripping ball 2, and the air inlet connection port 21 is connected and conducted to the air pressure sensor 413 through a hose, and the air inlet connection port 21 is convenient for the inflatable soft gripping ball 2 to be connected to the hose for air supply; an air outlet connection port 22 is provided on the inflatable soft gripping ball 2, and the air outlet connection port 22 is connected and conducted to the first air release valve 412 through a hose, and the air outlet connection port 22 is convenient for the inflatable soft gripping ball 2 to be connected to the hose for deflation.
