AI Technical Summary
In the current technology, the training of arteriovenous fistulas mainly relies on the patient to complete it independently. Some patients cannot obtain an arteriovenous fistula that can be used for dialysis on time due to limb inconvenience, inflexibility or poor mental state, which affects the timely performance of hemodialysis.
By controlling the first and second auxiliary modules to apply pressure to the limbs at both ends of the fistula, passive training of the fistula's compression movements is achieved, including clenching the fist and squeezing the arm. Combined with voice prompts, the training movements are standardized until the preset number of times or duration is reached.
Without relying on the patient's own actions, arteriovenous fistulas that can be used for dialysis can be obtained on time, ensuring timely hemodialysis, adapting to the patient's poor limb and mental state, and ensuring the patient's health.

Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of medical auxiliary equipment, in particular to a kind of arteriovenous fistula training control method, device and storage medium. BACKGROUND
[0002] Hemodialysis is a kind of kidney replacement therapy, mainly used for the treatment of patients with chronic renal failure. This treatment method replaces the kidney to filter the waste and excess water in the blood through a machine, maintains the acid-base balance, water balance and electrolyte balance of the body. Hemodialysis usually needs to be performed 2-4 times a week, each time lasting 3-5 hours. In order to do hemodialysis, blood vessel access needs to be established in advance. Arteriovenous fistula (AVF) has the advantages of good long-term dialysis effect, high survival rate, low infection rate and low thrombosis rate, and is a commonly used blood vessel access.
[0003] Establishing arteriovenous fistula requires performing arteriovenous fistuloplasty first. Arteriovenous fistuloplasty refers to anastomosing the artery near the wrist of the forearm and the adjacent vein, so that the anastomosed vein flows with arterial blood. The blood flow of arteriovenous fistula cannot be too high or too low. Generally speaking, the blood flow of arteriovenous fistula requires a minimum of 400-500 mL / min to ensure the flow rate requirement of hemodialysis, and the maximum blood flow of arteriovenous fistula cannot exceed 2000 mL / min, otherwise it will increase the heart load and cause heart failure.
[0004] However, the original vein is relatively thin and narrow, and direct use as an arteriovenous fistula cannot meet the blood flow requirement. The fragile original vein is also prone to lose blood supply due to vascular wall damage, infection, etc. Once the internal fistula at this place fails, arteriovenous fistuloplasty needs to be performed again at other parts of the patient's body. On the one hand, multiple operations will inevitably increase the patient's physical load, and on the other hand, the number of suitable locations for arteriovenous fistuloplasty in the human body is limited. Therefore, it is very important to maintain the effectiveness of the surgically formed fistula, and one of the more mainstream methods is to strengthen the training of the fistula to make it develop thicker.
[0005] Currently, the training of arteriovenous fistula mainly relies on the patient's self-completion. Some patients may not be able to complete the training flexibly due to physical inconvenience, some patients may not achieve the training effect due to non-standard training movements, and some patients may not be willing to complete the training independently due to poor mental state. Therefore, the arteriovenous fistula that can be used for dialysis puncture cannot be obtained on time, which leads to the delay of hemodialysis and affects the patient's physical health. SUMMARY

Without more limitations, the element defined by the statement "including a" does not exclude the presence of other identical elements in the process, method, article or device including the element.
[0037] In one embodiment, as Figure 1 ,2 As shown, an arteriovenous fistula training control method includes: controlling a second auxiliary module to press a limb at a proximal end of the fistula; during the duration of the pressing, controlling a first auxiliary module to drive a limb at a distal end of the fistula to generate a pressurizing movement, so as to pressurize the inside of the fistula; and repeatedly performing the above actions until a preset number of times or a preset training duration is reached.
[0038] Specifically, a training plan is first acquired, the training plan including a preset number of times or a preset training duration. The training plan can be set according to a doctor's order. The age, physical condition, and illness of the patient can affect the position and state of the fistula. According to the difference in the position and state of the fistula, the training plan for the fistula will also be different. Moreover, the training plan for the same fistula will also change at different development stages. The control method of the embodiment first acquires the training plan of the corresponding fistula, and then simultaneously controls the limbs at both ends of the fistula by using the first auxiliary module and the second auxiliary module, so as to pressurize the inside of the fistula, which can help the patient to passively complete the training of the fistula. Without relying on the autonomous action of the patient, the arteriovenous fistula that can be used for dialysis puncture can be obtained on time, which facilitates the timely performance of hemodialysis and ensures the physical health of the patient.
[0039] In other embodiments, the training plan can also be a plan set by the patient autonomously, which facilitates the patient to carry out the training of the fistula at any time by using the arteriovenous fistula training control method in fragmented time, and improves the development speed of the fistula training.
[0040] In one embodiment, the first auxiliary module is controlled to drive the limb at the distal end of the fistula to generate a pressurizing movement, specifically: the first auxiliary module is controlled to drive the hand at the distal end of the fistula to clench the fist. The second auxiliary module is controlled to press the limb at the proximal end of the fistula, specifically: the second auxiliary module is controlled to squeeze the arm at the proximal end of the fistula. The arteriovenous fistula in the embodiment is formed on the arm of the patient, and therefore the control method of the embodiment simultaneously controls the hand at the distal end of the fistula and the arm at the proximal end of the fistula by using the first auxiliary module and the second auxiliary module, and completes the training plan for the fistula by controlling the clenching and unclenching of the hand and the squeezing and releasing of the arm. This control method can help the patient to train the fistula in the case of inconvenience of the patient's limbs, and the control method controls the training of the patient according to the training plan, the action is standardized, and the training effect is good. Even in the case that the patient is in poor mental state and unwilling to autonomously complete the training, the control method of the embodiment can control the patient's limbs to passively complete the training plan, so as to obtain the arteriovenous fistula that can be used for dialysis puncture on time, which facilitates the timely performance of hemodialysis.
[0041] In one embodiment, the first auxiliary module is controlled to drive the limb at the distal end of the fistula to generate a pressurized movement, and the method further comprises: detecting a pressurized value of the pressurized movement of the limb at the distal end of the fistula, and adjusting the pressurized movement until a preset pressure is reached when the pressurized value is less than the preset pressure. Specifically, the training plan further comprises the preset pressure, which can be set according to the age, physical condition, etc. of the patient. Controlling the pressure value of the grip ball 52 to reach the predetermined pressure can regulate the patient's training, and the patient's training is synchronized with the force effect, which can achieve the training goal faster and obtain a well-developed fistula. The grip ball 52 can be arranged on the path of the pressurized movement of the limb at the distal end of the fistula, and a pressure sensor is arranged on the grip ball 52. The pressure sensor is used to detect the pressurized value of the pressurized movement of the limb at the distal end of the fistula. In other embodiments, the pressure sensor can also be arranged on the first auxiliary module.
[0042] In one embodiment, the first auxiliary module is controlled to drive the limb at the distal end of the fistula to generate a pressurized movement, and the method further comprises: determining a pressurized duration of the pressurized movement of the limb at the distal end of the fistula, and continuing the pressurized movement until a preset pressurized duration is reached when the pressurized duration is less than the preset pressurized duration. The above-mentioned actions are performed multiple times until a preset number of times / preset training duration is reached, and specifically: a rest duration is determined, and the next pressurizing and pressurizing action is started after the last pressurized movement is stopped for the rest duration. Achieving sufficient pressurized duration and rest duration can also better ensure the training effect.
[0043] In one embodiment, the first auxiliary module is controlled to drive the limb at the distal end of the fistula to generate a pressurized movement, and the method further comprises: detecting a pressurized value of the pressurized movement of the limb at the distal end of the fistula and a pressurized duration, and controlling the first auxiliary module and the second auxiliary module to be released when the pressurized value reaches a preset pressure and the pressurized duration reaches a preset pressurized duration. The above-mentioned actions are performed multiple times until a preset number of times / preset training duration is reached, and specifically: a rest duration is determined, and the next pressurizing and pressurizing action is started after the last pressurized movement is stopped for the rest duration.
[0044] Generally, the patient can increase the intensity of the training after 5 days after the arteriovenous fistula formation surgery, and thus the ball holding training plan can be performed. The ball holding training plan includes a preset pressure, a preset pressure maintaining time, an interval time, and a preset number of times / preset training time. Specifically, the first auxiliary module is controlled to drive the hand at the distal end of the fistula to squeeze the ball 52 in the palm, and the second auxiliary module is controlled to press the upper arm at the proximal end of the fistula. After the preset pressure is reached and the preset pressure maintaining time is maintained, the first auxiliary module is controlled to drive the hand at the distal end of the fistula to release the ball 52 in the palm, and the second auxiliary module is controlled to release the pressure on the upper arm at the proximal end of the fistula. The interval time is maintained, which is one training. The ball holding training plan is repeated for the preset number of times / preset training time to complete a set of training. The fistula training control method in this embodiment can help the patient to passively complete the moderate-intensity training of the fistula, and promote the further development of the fistula.
[0045] In one embodiment, the first auxiliary module is controlled to drive the limb at the distal end of the fistula to generate a pressure filling movement, and specifically further includes: detecting a pressure filling value and a pressure filling time, and when the pressure filling value reaches a preset pressure and the pressure filling time reaches a preset pressure maintaining time, the first auxiliary module is controlled to release the state for a duration of the pressure applied by the second auxiliary module. The above-mentioned actions are performed multiple times until the preset number of times / preset training time is reached, specifically: an interval time is determined, and after the interval time is reached after stopping the last pressure filling movement, the next pressure filling movement is started.
[0046] In addition to the ball holding training plan, the patient can also perform the blocking training plan with further increased intensity after 5 days after the arteriovenous fistula formation surgery. The blocking training plan includes a preset pressure, a preset pressure maintaining time, a preset number of times / preset training time, and an interval time. Specifically, the second auxiliary module is controlled to continuously press the upper arm at the proximal end of the fistula, the first auxiliary module is controlled to drive the hand at the distal end of the fistula to hold the ball 52 to reach the preset pressure and maintain the preset pressure maintaining time, and then the first auxiliary module is controlled to release the state and maintain the interval time, that is, the hand is in a state of releasing the ball 52. The first auxiliary module is controlled to repeat the ball holding and releasing movement of the hand until the preset number of times / preset training time is reached, and the first auxiliary module and the second auxiliary module are both controlled to release the state and stop the intervention on the limbs at both ends of the fistula, which is one training. The arteriovenous fistula training control method in this embodiment can further strengthen the fistula of the patient and help the rapid development of the fistula.
[0047] In one embodiment, the control method controls the first auxiliary module to drive the limb at the distal end of the fistula to generate the inflation movement, and specifically further comprises: synchronously issuing a voice prompt for the limb to generate the inflation movement. Specifically, when the control method controls the first auxiliary module to drive the patient to clench the fist, unclench the fist, clench the ball, unclench the ball, and controls the second auxiliary module to press the arm at the proximal end of the fistula and stop pressing the arm, the synchronous voice prompt for the patient to perform the corresponding control operation can relieve the tension of the patient when the force changes suddenly, so that the patient can complete the training plan in a more relaxed mood. In other embodiments, when the fistula to be trained is arranged in the foot area, the voice prompt will be a corresponding foot inflation movement voice prompt.
[0048] The foregoing embodiments are all passive training of the patient under the control of the control method. In other embodiments, if the patient's limb and mental state are good, the patient can also complete the training autonomously under the assistance of the control method according to the voice prompt. Generally, the patient can perform early exercise within three days after the arteriovenous fistula formation surgery, can perform finger movement (autonomous training), and can perform clenching movement every day according to the voice prompt, 3-4 times a day, and 10-15 minutes each time. Or when the empty-handed clenching training plan is performed, the patient actively clenches the fist according to the voice prompt, and at the same time, the control method controls the second auxiliary module to press the arm at the proximal end of the fistula of the patient, maintains for 3-5 seconds, and then the patient actively unclenches the fist according to the voice prompt, and at the same time, the control method controls the second auxiliary module to release the control state, also maintains for 3-5 seconds, and completes one training. In other embodiments, when the ball clenching training plan and the blockage training plan are performed, the patient can also complete the training autonomously under the assistance of the control method according to the voice prompt.
[0049] In one embodiment, an arteriovenous fistula training device comprises: a first auxiliary module acting on one end of the fistula and having a first pressing state for driving the limb to move to inflate the fistula and a first relaxation state for adapting to the free movement of the limb; a second auxiliary module acting on the other end of the fistula and having a second pressing state for pressing the limb to prolong the inflation time of the fistula and a second relaxation state for allowing the limb to move freely; and a central control module 1 signal connected with the first auxiliary module and the second auxiliary module and controlling the first auxiliary module to switch between the first relaxation state and the first pressing state and controlling the second auxiliary module to switch between the second relaxation state and the second pressing state.
[0050] Specifically, the first auxiliary module acts on the hand at one end of the fistula, the first pressing state includes driving the fingers to be close to the palm, and the first relaxation state includes a state of adapting to the free movement of the hand; the second auxiliary module acts on the arm at the other end of the fistula, the second pressing state includes pressing the arm, and the second relaxation state includes a state of allowing the arm to move freely.
[0051] In use, the patient places the hand at the first auxiliary module so that the first auxiliary module can act on the hand, and places the proximal end of the upper arm at the second auxiliary module so that the second auxiliary module can act on the proximal end of the upper arm, which refers to the end of the upper arm on the side of the fistula close to the shoulder. The central control module 1 drives the first auxiliary module to switch from the first relaxed state to the first pressing state, so that the fingers are close to the palm, and simultaneously drives the second auxiliary module to switch from the second relaxed state to the second pressing state, so that the proximal end of the upper arm is in a squeezed state. The first auxiliary module and the second auxiliary module cooperate, and the proximal end of the upper arm is squeezed to moderately dilate the veins and increase blood flow. The fingers close to the palm in a fist state can increase the tension of the blood vessel wall, promote the growth of vascular endothelial cells and vascular remodeling, and thus promote the fistula to become thick and mature.
[0052] To prevent the problems of blood vessel injury or ischemia that may be caused by long-term compression or continuous fist of the upper arm, the central control module 1 also drives the first auxiliary module to switch from the first pressing state to the first relaxed state, so that the fingers are free to stretch away from the palm, and simultaneously drives the second auxiliary module to switch from the second pressing state to the second relaxed state, so that the upper arm is no longer squeezed by the second driving module, reducing excessive compression of the blood vessels, preventing damage to the blood vessels, and avoiding necrosis of the upper arm due to ischemia.
[0053] The central control module 1 controls the first auxiliary module and the second auxiliary module, so that the hand can cyclically clench and unclench, and the upper arm can be compressed or released at the same time. The patient's hand with the fistula can automatically complete the cyclic training of the fistula under the driving of the fistula training device. The training action is standardized, and the patient can complete the training even if the upper limb is not flexible. The patient can also passively complete the training if the patient's mental state is not good. The patient can obtain a fistula for dialysis puncture on time, and timely blood dialysis, ensuring the health of the patient.
[0054] In one embodiment, as Figure 3 、 4As shown, the first auxiliary module includes a palm limiting piece 5 matched with the palm, a finger limiting piece 54 matched with the fingers, and a first driving piece. The central control module 1 is electrically connected with the first driving piece. When the first auxiliary module is switched from the first relaxed state to the first pressing state, the first driving piece drives the finger limiting piece 54 to be fixed at a position close to the palm limiting piece 5. Specifically, the finger limiting piece 54 is made of flexible material. One end of the finger limiting piece 54 and one end of the palm limiting piece 5 are rotationally connected through a rotating shaft. The finger limiting piece 54 is internally provided with a first cavity, and the first cavity can be filled with gas. The first driving piece includes a first gas control mechanism. The first gas control mechanism is in communication with the first cavity, and is used for inflating or deflating the first cavity. After the first cavity is inflated, the finger limiting piece 54 rotates around the rotating shaft and is located at a position close to the palm limiting piece 5.
[0055] In use, the palm and the arm can be respectively placed on the palm limiting piece 5 and the finger limiting piece 54. The central control module 1 sends a command to the first gas control mechanism, so that the first gas control mechanism inflates the first cavity. After the flexible finger limiting piece 54 is inflated, it can reach a preset position, i.e., it can be close to the palm limiting piece 5, so as to drive the fingers placed on the finger limiting piece 54 to be close to the palm placed on the palm limiting piece 5, and perform a fist action. The central control module 1 also sends a command to the first gas control mechanism, so that the first gas control mechanism deflates the first cavity. The gas filled in the first cavity is released, the flexible finger limiting piece 54 loses the supporting force, and then the finger limiting piece 54 also loses the limiting effect on the fingers, and the fingers can be freely relaxed. Thus, the central control module 1 can send a command to the first gas control mechanism to drive the first gas control mechanism to inflate or deflate the first cavity, and then the finger limiting piece 54 can drive the fingers to be close to the palm to perform a fist action, and the finger limiting piece 54 can cancel the limitation on the fingers, and the hand can be relaxed, so as to realize the alternating fist and relaxed fist, and complete the hand action in the training of the arteriovenous fistula.
[0056] Specifically, the first pneumatic mechanism can include a compressed air pump and a vacuum air pump. The compressed air pump can compress air or other gas into high-pressure gas and be used to inflate the first cavity. The vacuum air pump can create a vacuum and be used to deflate the first cavity. In other embodiments, the deflation of the first cavity can also use an electronic controller and a deflation valve. The electronic controller receives instructions from the central control module 1 and controls the deflation valve to open, releasing the gas in the first cavity, so that the first cavity returns to the initial state without filling gas. In other embodiments, the first cavity can also be filled with water or other fluids to provide support force for the finger limiting member 54 to drive the hand to clench, and then release the filled fluid, so that the hand can naturally unclench. The compressed air pump and the vacuum air pump can be arranged on the back of the finger limiting member 54, or can be arranged on other parts, such as the central control module 1. The compressed air pump and the vacuum air pump can be respectively connected to the first cavity through air pipes and deflate the first cavity.
[0057] In other embodiments, the first driving member can also be a connecting rod and a hydraulic cylinder driving the connecting rod. One end of the finger limiting member 54 and one end of the palm limiting member 5 are fixedly connected, and the output end of the connecting rod and the end of the finger limiting member 54 away from the palm limiting member 5 are drivingly connected. The hydraulic rod drives the connecting rod to extend and retract, the connecting rod drives the finger limiting member 54 to approach or move away from the palm limiting member 5, and the alternating cycle training of the hand clenching and unclenching is realized.
[0058] In one embodiment, the finger limiting member 54 is provided with a finger sleeve 53, and the fingers can be sleeved in the finger sleeve 53 and fixed on the finger limiting member 54 by the finger sleeve 53. The finger sleeve 53 can be arranged at the end away from the palm limiting member 5, and can fully drive the movement of the fingers to clench. The finger sleeve 53 can be provided with five finger cavities corresponding to five independent fingers, so that the control of the fingers by the finger driving member is more accurate. The four fingers except the thumb can also be arranged in the same cavity of the finger sleeve 53, which is convenient for the patient to wear. The finger sleeve 53 can also be selected according to the season to fully cover the fingers or half cover the fingers. The fully covered fingers can fully cover the patient's fingers in the finger sleeve 53, and the warmth is better. The half-covered fingers, that is, the tips of the fingers can be partially exposed, and the breathability is better. The finger sleeve 53 is used to fix the fingers, so that the fingers can stably clench under the drive of the finger driving member. In other embodiments, elastic ropes, buckles or other mechanisms can be used to fix the fingers on the finger limiting member 54.
