Description

Technical Field

[0001] The present invention belongs to the technical field of rehabilitation equipment, and in particular relates to an individualized distal ischemia training device and method based on hemodynamic characteristics. Background Art

[0002] Remote ischemic preconditioning (RIPC) is a biological mechanism that helps protect organs and tissues from ischemia and reperfusion. In medical research, RIPC usually involves a protective state induced by temporarily restricting blood flow before an organ or tissue is about to experience ischemia (such as surgery or heart attack). The pre-application scope of RIPC mainly includes the following aspects: (1) Brain protection: In patients with cerebrovascular accidents (such as stroke), RIPC can help reduce the neurological damage caused by ischemia. (2) Heart protection: In cardiac surgery (such as coronary artery bypass grafting), RIPC can be used to reduce myocardial ischemia-reperfusion injury. For patients with acute myocardial infarction, RIPC can be used as an adjuvant treatment for heart protection. (3) Kidney protection: In kidney surgery or kidney transplantation, RIPC may help reduce the risk of ischemic damage to the kidneys.

[0003] For example, in cardiovascular and cerebrovascular diseases, ischemic or hemorrhagic diseases of the heart, brain and systemic tissues caused by hyperlipidemia, blood viscosity, atherosclerosis, hypertension, etc., combined with ischemic training devices, can promote adaptive changes in the heart and blood vessels by temporarily restricting blood flow, so that other important organs such as the heart and brain will activate protective mechanisms under hypoxic conditions, promote blood flow redistribution and improve blood supply, so as to enhance the tolerance of the heart and brain tissues and improve cardiovascular endurance and function. This adaptive training helps to improve the patient's exercise ability and overall health level.

[0004] The currently available remote ischemic preconditioning training device realizes ischemic training by applying pressurization to the upper limbs through a cuff. The pressurized cuff used needs to be connected to the pressurization host through a connecting pipe before use. During the training operation, the host needs to set parameters such as pressurization pressure value, number of training times, and training duration. The steps are cumbersome and the overall user experience is poor. Summary of the invention

[0044] Support parts 3 are fixedly provided on both sides of the adjustment part 2. The support parts 3 can be opened and closed, and provide support and fixation for the arm placed inside in the closed state;

[0045] The support part 3 is provided with an inflatable part 4 inside, and the inflatable part 4 can inflate inside the support part 3 to squeeze the arm inside the support part 3, so that the blood supply inside the arm is reduced to achieve the purpose of ischemia;

[0046] A control unit 5 is provided at the armrest of the seat 1, the control unit 5 is connected to the mains, and the control unit 5 is electrically connected to the support unit 3 and the inflatable unit 4;

[0047] The supporting part 3 includes a supporting seat 301, a driving motor 302, a driving worm 303, a driving gear 304, a driving rod 305, a follower gear 306 and a moving plate 307. One side of the supporting seat 301 is fixedly connected to one side of the adjusting part 2. The driving motor 302 is fixedly arranged inside the supporting seat 301. The driving worm 303 is fixedly connected to the output end of the driving motor 302. The driving gear 304 is meshed with the outer edge of the driving worm 303. The driving gear 304 is fixedly connected to the inside of the supporting seat 301. The driving rod 305 is rotationally arranged inside the supporting seat 301. One end of the driving rod 305 is fixedly connected to the tooth center of the driving gear 304. A plurality of follower gears 306 are provided, and the tooth center of the follower gear 306 is fixedly connected to the outer edge of the driving rod 305. The moving plate 307 is slidingly arranged inside the supporting seat 301. The outer side of the moving plate 307 is meshed with the outer edge of the follower gear 306.

[0048] Specifically, when a person needs to perform ischemic training, the person only needs to sit inside the seat 1, and then place both arms inside the support groove of the support seat 301, and then use both shoulders of the person to squeeze the support seat 301 to drive the sliding arm 202 to slide inside the fixed seat 201, so as to adjust the position of the support seat 301 to adapt to people with different shoulder widths, thereby improving the adaptation range of the equipment;

[0049] Then, the personnel controls the driving motor 302 to rotate through the control unit 5, and the driving motor 302 drives the driving worm 303 to rotate, and the rotation of the driving worm 303 drives the meshing driving gear 304 to rotate, and the rotation of the driving gear 304 drives the driving rod 305 fixedly connected at the tooth center to rotate, and the rotation of the driving rod 305 drives the meshing moving plate 307 to slide out of the interior of the support seat 301, and at the same time, the moving plate 307 can drive the middle part of the airbag sheet 402 to move out of the interior of the support seat 301, so as to realize the movement of the moving plate 307, until the extension of the moving plate 307 closes the upper end opening of the support seat 301, at this time, the support unit 3 enters the closed state, and the personnel's arm is limited between the support seat 301 and the moving plate 307, and the arm is also wrapped by the airbag sheet 402, so as to complete the limitation of the personnel's arm;

[0050] Then the person controls the inflation part 4 to inflate through the control part 5, so that the airbag sheet 402 expands inside the support seat 301 and the movable plate 307. Since the airbag sheet 402 is limited by the structure of the support seat 301 and the movable plate 307, the inflation pressure of the airbag is applied to the person's arm, thereby reducing the blood supply to the person's arm and achieving the purpose of arm ischemia;

[0051] After the ischemic training is finished, the person first controls the inflation part 4 to exhaust air through the control part 5 so that the airbag sheet 402 returns to a flat state, so that the person's arm is no longer squeezed and the normal blood supply to the arm is restored;

[0052] The personnel controls the driving motor 302 through the control unit 5 to drive the driving worm 303 to rotate in the opposite direction. The opposite rotation of the driving worm 303 drives the meshing driving gear 304 to rotate in the opposite direction. The opposite rotation of the driving gear 304 drives the driving rod 305 fixedly connected at the tooth center to rotate in the opposite direction. The rotation of the driving rod 305 drives the meshing moving plate 307 to slide and shrink into the interior of the support seat 301. At the same time, the inflatable unit 4 can drive the moving plate 307 of the airbag sheet 402 to move and shrink into the interior of the support seat 301, thereby realizing the movement and opening of the moving plate 307, until the moving plate 307 is completely retracted into the interior of the support seat 301 and restores to the open state. At this time, the arm can be moved out of the support groove and leave the interior of the seat 1, completing the entire process of ischemia training.

[0053] See also Figures 1 to 3 As shown, a support groove is provided inside the support seat 301, and the support groove cooperates with the arm to provide a space for the arm to be placed. At the same time, the shoulders of a person can also be used to provide support inside the support groove to prevent the support seat 301 from shrinking together with the sliding arm 202.

[0054] See also Figures 3 to 5 As shown, the movable plate 307 is overall arc-shaped, and the inner side of the arc matches the inside of the support groove. The inner side of the movable plate 307 in the extended state and the support groove form a limiting cylinder. The limiting cylinder can not only limit the person's arm inside, but also limit the expansion pressure of the airbag sheet 402, so that more expansion pressure of the airbag sheet 402 can be applied to the person's arm, thereby enhancing the pressure effect.

[0055] See also Figure 4 and Figure 5 As shown, the outer edge of the movable plate 307 is provided with a plurality of tooth grooves which match the follower gear 306, and the tooth grooves are meshed with the outer edge of the follower gear 306. During the rotation of the follower gear 306, pressure can be applied to the tooth grooves so that the movable plate 307 can slide inside the support seat 301, thereby realizing the arc-shaped movement, extension and contraction of the movable plate 307.

[0056] See also Figure 2 As shown, the adjustment part 2 includes a fixed seat 201, a sliding arm 202 and an elastic reset member 203. The fixed seat 201 is fixedly connected to the backrest of the seat 1. Two sliding arms 202 are provided. One end of the two sliding arms 202 is slidably connected to the inside of the fixed seat 201, and the other end of the sliding arm 202 is fixedly connected to the support seat 301. When the support seat 301 moves, the sliding arm 202 is driven to slide and extend inside the fixed seat 201, so as to adapt to the shoulder width of different people and improve the applicable scope of the equipment. The elastic reset member 203 is arranged between the sliding arm 202 and the fixed seat 201. When the sliding arm 202 is not driven, the elastic force of the elastic reset member 203 is released to drive the sliding arm 202 to slide to the initial position, thereby realizing automatic adjustment and recovery of the sliding arm 202.

[0057] See also Figure 5 and Figure 6 As shown, the inflation portion 4 includes an air pump 401, an airbag sheet 402, a sliding seat 403 and an elastic extrusion member 404, the air pump 401 is fixedly connected to the interior of the support seat 301, the interior of the airbag sheet 402 is connected to the output end of the air pump 401 through an air pipe, both ends of the airbag sheet 402 are fixedly connected to the support seat 301, and the middle part of the airbag sheet 402 is in sliding contact with the interior of the support seat 301, the middle part of the airbag sheet 402 is in sliding connection with the interior of one end of the moving plate 307, both ends of the airbag sheet 402 are fixedly connected to the interior of the support seat 301, the sliding seat 403 is slidably arranged in the interior of the support seat 301, and the middle part of the sliding seat 403 is matched with the middle part of the airbag sheet 402, and the elastic extrusion member 404 is arranged between the sliding seat 403 and the support seat 301;

[0058] When the moving plate 307 is extended, one end of the moving plate 307 can drive the middle part of the airbag sheet 402 to move out of the support seat 301. At the same time, the airbag sheet 402 is limited by its own length, and the bending part of the airbag sheet 402 drives the sliding seat 403 to move together, so as to supplement the length of the airbag sheet 402 required to surround the person's arm, thereby achieving flexible adaptation to the person's arm.

[0059] The air pump 401 is controlled by the control unit 5 to pump air into the airbag sheet 402. At this time, the airbag sheet 402 begins to expand and squeeze the arm of the person inside the support seat 301 and the moving plate 307, reducing the blood flow in the arm of the person to achieve arm ischemia;

[0060] After the airbag sheet 402 is deflated, the sliding seat 403 loses the limiting movement of the airbag sheet 402 during the process of the movable plate 307 shrinking into the interior of the support seat 301. At this time, the sliding seat 403 moves to the initial position due to the extrusion force of the elastic extrusion member 404 elastically recovered. At the same time, the sliding seat 403 pulls the airbag sheet 402 to shrink into the interior of the support seat 301.

[0061] See also Figure 5 and Figure 6 As shown, the airbag sheet 402 is arranged inside the support seat 301 in a bent state, one end of the airbag sheet 402 is fixedly connected to the inside of the support groove, the airbag sheet 402 and the input end of the air pump 401 are inside the support groove, so that the airbag sheet 402 first begins to expand inside the support groove, and the other end of the airbag sheet 402 is fixedly connected to the deep inside of the support seat 301. During the expansion process of the airbag sheet 402, the airbag sheet 402 inside the support seat 301 will also expand, but will not over-expand due to the structural limitation of the support seat 301, and most of its pressure is still inside the support seat 301. The bent inner side of the airbag sheet 402 is slidably connected to the middle part of the sliding seat 403. During the process of the middle part of the airbag sheet 402 moving with the movable plate 307, the airbag sheet 402 is subject to length limitation, and the middle part of the airbag sheet 402 slides at the sliding seat 403 while exerting pressure on the sliding seat 403, causing the sliding seat 403 to move.

[0062] See also Figure 5 and Figure 6 As shown, an air pressure sensor is provided at the output end of the air pump 401, and the air pressure sensor is used to monitor the air pressure inside the airbag sheet 402. The air pressure sensor sends the monitored data to the control unit 5, so that the control unit 5 can timely adjust the gas pressure inside the airbag sheet 402 to a normal state, so as to avoid the internal pressure of the airbag sheet 402 being too high to injure the person's arm, and the air pressure being too low to achieve the purpose of reducing blood flow.

[0063] See also Figure 1 As shown, the control unit 5 is internally integrated with a control button and a processor, the processor is connected to the mains, the control button is electrically connected to the processor, the processor is electrically connected to the air pump 401, the air pressure sensor and the drive motor 302, the air volume of the air pump 401 is controlled by the processor, and the air pressure data of the airbag sheet 402 collected by the air pressure sensor is collected in real time to reach a predetermined value; the processor controls the drive motor 302 to extend and retract the movable plate 307.

[0064] A method for individualized distal ischemia training based on hemodynamic characteristics is applied to an individualized distal ischemia training device based on hemodynamic characteristics, comprising the following steps;

[0065] Step 1: The person who needs to be trained sits inside the seat 1;

[0066] Step 2: The person places both arms inside the support groove, and can use both shoulders to squeeze the support seat 301 to drive the sliding arm 202 to slide inside the fixed seat 201, so as to adjust the position of the support seat 301 to adapt to people with different shoulder widths;

[0067] Step 3: The personnel controls the support part 3 to enter the closed state through the control part 5, and controls the arm inside the support groove;

[0068] Step 4: The person controls the inflation part 4 to inflate through the control part 5, so that the airbag sheet 402 expands inside the support part 3 and squeezes the person's arm;

[0069] Step 5: After the training is finished, the personnel firstly controls the inflation part 4 to exhaust air through the control part 5 so that the airbag sheet 402 returns to a flat state;

[0070] Step 6: The personnel controls the support part 3 to open through the control part 5, and then the arm can be moved out of the support groove.

[0071] The working principle of the present invention is as follows: when a person needs to perform ischemic training, the person only needs to sit inside the seat 1, and then place both arms inside the support groove of the support seat 301, and then use the shoulders of the person to squeeze the support seat 301 to drive the sliding arm 202 to slide inside the fixed seat 201, so as to adjust the position of the support seat 301 to adapt to people with different shoulder widths, thereby improving the adaptation range of the equipment;

[0072] Then, the personnel controls the driving motor 302 to rotate through the control unit 5, and the driving motor 302 drives the driving worm 303 to rotate, and the rotation of the driving worm 303 drives the meshing driving gear 304 to rotate, and the rotation of the driving gear 304 drives the driving rod 305 fixedly connected at the tooth center to rotate, and the rotation of the driving rod 305 drives the meshing moving plate 307 to slide out of the interior of the support seat 301, and at the same time, the moving plate 307 can drive the middle part of the airbag sheet 402 to move out of the interior of the support seat 301, so as to realize the movement of the moving plate 307, until the extension of the moving plate 307 closes the upper end opening of the support seat 301, at this time, the support unit 3 enters the closed state, and the personnel's arm is limited between the support seat 301 and the moving plate 307, and the arm is also wrapped by the airbag sheet 402, so as to complete the limitation of the personnel's arm;

[0073] Then the person controls the inflation part 4 to inflate through the control part 5, so that the airbag sheet 402 expands inside the support seat 301 and the movable plate 307. Since the airbag sheet 402 is limited by the structure of the support seat 301 and the movable plate 307, the inflation pressure of the airbag is applied to the person's arm, thereby reducing the blood supply to the person's arm and achieving the purpose of arm ischemia;

[0074] After the ischemic training is finished, the person first controls the inflation part 4 to exhaust air through the control part 5 so that the airbag sheet 402 returns to a flat state, so that the person's arm is no longer squeezed and the normal blood supply to the arm is restored;

[0075] The personnel controls the driving motor 302 through the control unit 5 to drive the driving worm 303 to rotate in the opposite direction. The opposite rotation of the driving worm 303 drives the meshing driving gear 304 to rotate in the opposite direction. The opposite rotation of the driving gear 304 drives the driving rod 305 fixedly connected at the tooth center to rotate in the opposite direction. The rotation of the driving rod 305 drives the meshing moving plate 307 to slide and shrink into the interior of the support seat 301. At the same time, the inflatable unit 4 can drive the moving plate 307 of the airbag sheet 402 to move and shrink into the interior of the support seat 301, thereby realizing the movement and opening of the moving plate 307, until the moving plate 307 is completely retracted into the interior of the support seat 301 and restores to the open state. At this time, the arm can be moved out of the support groove and leave the interior of the seat 1, completing the entire process of ischemia training.

[0076] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
