Description

Technical Field

[0001] This invention relates to the field of postoperative rehabilitation technology, and in particular to a rehabilitation training device for patients after interventional treatment of coronary heart disease. Background Technology

[0002] Coronary artery disease is a common heart disease that seriously endangers human health, causing extremely serious adverse effects on patients' quality of life and even threatening their lives. It also places a heavy burden on patients' families and the country. Currently, drug therapy, coronary artery bypass grafting, and percutaneous coronary intervention are three important means of treating coronary disease. Among them, percutaneous coronary intervention has developed the most rapidly and is less invasive, has a faster recovery, and has significant clinical effects.

[0003] Patent CN219272081U discloses a rehabilitation training device after coronary intervention, comprising a seat plate, a fixed column fixed to the middle of the lower surface of the seat plate, and a base plate fixed to one end of the fixed column. Rotating columns are movably connected to both sides of the upper surface of the base plate via bearing seats. One end of each of the two rotating columns passes through the upper surface of the seat plate and is fixedly connected to a rotating rod. A first gear is fixedly connected to the surface of each of the two rotating columns, and a second gear meshes with the surface of the first gear. A connecting rod is fixedly connected inside the second gear. This rehabilitation training device, through the structure of the base plate, rotating rods, first gear, second gear, and support plate, allows the patient to grip the surface of the anti-slip mat with both hands during training, and then exert force to drive the rotating rods to rotate synchronously, thereby training the arms and potentially slowing the progression of coronary atherosclerosis to some extent.

[0004] Post-interventional treatment can only address local coronary artery stenosis or occlusion, but cannot eliminate risk factors for coronary heart disease. Therefore, it cannot treat the underlying cause of coronary atherosclerosis and its progression. Post-operative complications such as hematoma and infection at the puncture site may occur, necessitating the use of post-interventional rehabilitation devices. Traditional post-interventional rehabilitation devices typically use a foot pedal method to exercise the legs. However, prolonged use of this method can cause wear and tear on the knees of elderly patients and lacks a structured exercise program. Strenuous exercise can easily lead to an increase in heart rate and blood pressure, causing coronary heart disease recurrence and affecting the effectiveness of the rehabilitation. Therefore, a post-interventional rehabilitation device for coronary heart disease is proposed.

[0005] Therefore, this application provides a rehabilitation training device for patients after coronary intervention to meet the needs. Summary of the Invention

[0029] like Figure 1 - Figure 12 As shown, an embodiment of the present invention provides a rehabilitation training device after coronary intervention, including a support body 1: a display screen 2 is fixedly installed on the top of the support body 1, a hand crank device 3 is provided at the bottom of the display screen 2, a base 4 is fixedly installed at the bottom of the support body 1, a limiting mechanism 5 is provided inside the support body 1, a stepping mechanism 6 is provided on one side of the limiting mechanism 5, an adjustment mechanism 7 is provided on one side of the support body 1, a cavity 8 is opened inside the support body 1, and a positioning hole 9 is opened on one side of the hand crank device 3; The limiting mechanism 5 includes a first part group 51 and a second part group 52. The first part group 51 and the second part group 52 are symmetrically rotated around the second positioning shaft 503. The first part group 51 includes a first positioning block 501, a first positioning shaft 502, a second positioning shaft 503, a third positioning shaft 504, a first gear 505, a second gear 506, a third gear 507, a fourth gear 508, and a sub-rotating ring 509. The first positioning block 501 is fixedly installed inside the cavity 8. The top of the first positioning block 501... The device is equipped with a first positioning shaft 502, a second positioning shaft 503 on one side of the first positioning shaft 502, a third positioning shaft 504 on one side of the second positioning shaft 503, a first gear 505 fixedly mounted on one side of the third positioning shaft 504, a fourth gear 508 fixedly mounted on the other side of the second positioning shaft 503, a second gear 506 meshing with one side of the first gear 505, a third gear 507 meshing with one side of the fourth gear 508, and a sub-rotor ring 509 meshing with one side of the third gear 507.

[0030] The first component group 51 also includes a female rotating ring 510, a first bearing sleeve 511, a sliding sleeve 512, a crank 513, a positioning plate 514, a first spring 515, and a first limiting block 516. The female rotating ring 510 is movably connected to one side of the female rotating ring 509. The first bearing sleeve 511 is movably installed on one side of the third positioning shaft 504. The sliding sleeve 512 is movably connected to one side of the first bearing sleeve 511. The crank 513 is movably installed on one side of the sliding sleeve 512. The positioning plate 514 is fixedly connected to the bottom of the crank 513. The first limiting block 516 is movably connected to the bottom of the crank 513. The first spring 515 is fixedly installed on one side of the positioning plate 514.

[0031] The female rotating ring 510 is fixedly connected to one side of the second gear 506, one side of the first spring 515 is fixedly installed on one side of the first positioning block 501, and the first limiting block 516 is fixedly installed on the top of the first positioning block 501.

[0032] The second gear 506 has the same number of teeth as the first gear 505, and the third gear 507 has a greater number of teeth than the fourth gear 508.

[0033] Further explanation is needed: the first part group 51 includes parts on the third positioning shaft 504 and the second positioning shaft 503, and the second part group 52 includes parts on the first positioning shaft 502 and the second positioning shaft 503. The first part group 51 and the second part group 52 are rotated symmetrically with the second positioning shaft 503 as the central axis. The rotational speed of the gear between the first gear 505 and the second gear 506 needs to be greater than or less than the rotational speed of the gear between the third gear 507 and the fourth gear 508, so as to generate a speed difference between the second gear 506 and the third gear 507, which drives the sub-rotating ring 509 to move slowly on the curved groove opened on the mother rotating ring 510.

[0034] like Figure 6 , Figure 7 and Figure 8 As shown, the pedal mechanism 6 includes a first rocker 601, a first planetary gear 602, a second planetary gear 603, a first slider 604, a first slide rail 605, a second slider 606, a second slide rail 607, a second limiting block 608, a side plate 609, and a second bearing sleeve 610. The first rocker 601 is fixedly installed on one side of the third positioning shaft 504. The first planetary gear 602 is movably installed on one side of the first rocker 601. The second planetary gear 603 is meshed and driven on one side of the first planetary gear 602. The first slider 604 is movably connected to one side of the first planetary gear 602. The first slider 604 is movably connected inside the first slide rail 605. The second slider 606 is fixedly connected to one side of the first slide rail 605. The second slider 606 is movably installed inside the second slide rail 607. The second slide rail 607 is fixedly installed on one side of the second limiting block 608. The second limiting block 608 is fixedly installed on one side of the side plate 609. The second bearing sleeve 610 is fixedly installed on one side of the second slider 606.

[0035] The pedal mechanism 6 also includes a first pedal 611, an elastic band 612, a second pedal 613, a third slide rail 614, a second spring 615, a third slider 616, and a third pedal 617. The first pedal 611 is movably mounted on one side of the second bearing sleeve 610. The elastic band 612 is fixedly mounted on the top of the first pedal 611. The second pedal 613 is fixedly mounted on one side of the first pedal 611. The third pedal 617 is movably mounted on the other side of the first pedal 611. The third slider 616 is fixedly connected to one side of the third pedal 617. The third slide rail 614 is movably connected to one side of the third slider 616. The second spring 615 is provided on one side of the third slide rail 614.

[0036] One side of the second spring 615 is fixedly connected to the inside of the first pedal 611, and the other side of the second spring 615 is fixedly connected to one side of the third pedal 617.

[0037] The second planetary gear 603 is fixedly installed on one side of the side plate 609, and the first slide rail 605 is movably connected to one side of the second slide rail 607.

[0038] Further explanation is needed: when the first planetary gear 602 and the second planetary gear 603 mesh and transmit power, the first slider 604 on one side of the first planetary gear 602 slides up and down inside the first slide rail 605, while simultaneously driving the second slider 606 and the second bearing sleeve 610, which are fixedly connected to one side of the first slide rail 605, to move horizontally back and forth inside the second slide rail 607, thereby driving the first pedal 611, the second pedal 613 and the third pedal 617 to move horizontally back and forth simultaneously.

[0039] like Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the adjustment mechanism 7 includes a bracket 701, a base 702, a first slide groove 703, a fourth slider 704, a telescopic block 705, a seat 706, a first locking block 707, a second locking block 708, a connecting rod 709, a third locking block 710, a second positioning block 711, a second slide groove 712, a threaded shaft 713, a second crank 714, and a threaded hole 715. The bracket 701 is fixedly connected to the top of the base 4, and the base 702 is fixedly connected to the top of the bracket 701. The first slide groove 703 is opened on one side of the base 702. The fourth slider 704 is movably connected inside the first slide groove 703, and the telescopic block 705 is movably connected inside the fourth slider 704. A seat 706 is fixedly connected to the top of the telescopic block 705. A first locking block 707 is fixedly connected to the bottom of the seat 706. A second locking block 708 is movably connected to the bottom of the first locking block 707. A connecting rod 709 is movably connected to one side of the second locking block 708. A third locking block 710 is movably connected to one side of the connecting rod 709. One side of the third locking block 710 is movably connected to the inside of the second positioning block 711. A second sliding groove 712 is provided inside the second positioning block 711. A threaded shaft 713 is movably connected to one side of the second positioning block 711. A second rocker arm 714 is fixedly connected to one side of the threaded shaft 713. A threaded hole 715 is provided on one side of the base 702.

[0040] The threaded shaft 713 is movably sleeved inside the threaded hole 715, and the second locking block 708 is movably mounted on one side of the base 702.

[0041] Further explanation is needed: When the position of seat 706 needs to be adjusted, the second crank 714 is manually rotated to drive the threaded shaft 713 to rotate inside the threaded hole 715, thereby pushing the second positioning block 711 to move horizontally, and further driving the third locking block 710 and connecting rod 709 to move. The movement trajectory of the connecting rod 709 is an arc. A groove is opened on the side of the third locking block 710 to allow the connecting rod 709 to move. When the connecting rod 709 moves forward, it simultaneously drives the second locking block 708 to rotate around the shaft connected to the base 702 until the connecting rod 709 contacts the shaft at the connection between the second locking block 708 and the base 702. At this time, the angle between the second locking block 708 and the horizontal line is 20 degrees, and the first locking block 707 at the bottom of seat 706 is no longer engaged with the second locking block 708, so the position of seat 706 can be manually adjusted.

[0042] The technical solution provided by this invention, when using the rehabilitation training device, firstly, by manually rotating the second crank 714, the threaded shaft 713 is driven to rotate inside the threaded hole 715, thereby driving the second positioning block 711 to move horizontally, further driving the third locking block 710 to move up and down inside the second positioning block 711, and finally driving the connecting rod 709 on one side of the third locking block 710 to move in an arc, driving the second locking block 708 on one side of the connecting rod 709 to rotate around the axis at the connection between the second locking block 708 and the base 702. When the connecting rod 709 moves to the axis between the second locking block 708 and the base 702, the angle between the second locking block 708 and the horizontal line is 20 degrees. At this time, the first locking block 707 and the second locking block 708 are no longer engaged, and the seat 706 can be manually moved to adjust the position of the seat 706 on the base 702. After the seat 706 is adjusted, the second crank 714 is rotated in the opposite direction to drive the threaded shaft 713 to rotate, thereby driving the connecting rod 709 to reset. After the patient sits on the seat 706, the patient places their foot from the bottom of the elastic band 612 on top of the first pedal 611, the second pedal 613, and the third pedal 617, pushes the ball of the foot against the third pedal 617 and pushes it forward, causing the third slider 616 to move on one side of the third slide rail 614. After the patient aligns their heel with the groove on top of the second pedal 613, the third pedal 617 moves towards the first pedal 611 under the action of the second spring 615, thereby fixing the patient's foot on top of the first pedal 611, the second pedal 613, and the third pedal 617. Secondly, the patient pushes the first pedal 611 back and forth with the ball of his foot, which drives the second slider 606 on one side of the second bearing sleeve 610 to move horizontally inside the second slide rail 607, thereby driving the first planetary gear 602 and the second planetary gear 603 on one side of the first slide rail 605 to mesh and transmit power. When the first rocker arm 601 on one side of the first planetary gear 602 rotates, the third positioning shaft 504 rotates at the same time. Since the rotational speed between the third gear 507 and the fourth gear 508 is not equal to the rotational speed between the second gear 506 and the first gear 505, the sub-ring 509 on one side of the third gear 507 moves slowly on the curved groove on one side of the mother ring 510. When the patient moves the first pedal 611 a sufficient number of times, the sub-rotating ring 509 moves to the top of the curved groove of the mother rotating ring 510. At this time, under the action of the first spring 515, the crank 513 on one side of the positioning plate 514 moves towards the mother rotating ring 510, thereby driving the sub-rotating ring 509 to reset to the bottom of the mother rotating ring 510. During this process, the third gear 507 moves from one end of the fourth gear 508 to the other end, and the limiting mechanism 5 locks up to prevent the patient's strenuous exercise from causing a recurrence of coronary heart disease. To continue moving, simply move the first pedal 611 back and forth in the opposite direction.
