Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a cardiac rehabilitation exercise aid for patients after coronary artery disease PCI. Background Technology

[0002] Coronary artery disease (CAD) is a serious cardiovascular disease with a high incidence and mortality rate worldwide. Patients' coronary arteries narrow due to atherosclerosis, leading to insufficient blood supply to the myocardium and causing health problems such as angina and myocardial infarction. Percutaneous coronary intervention (PCI) is an important means of treating CAD. Through procedures such as balloon dilation or stent implantation, it can effectively widen the coronary arteries, restore blood supply to the myocardium, significantly relieve angina, and reduce the risk of myocardial infarction. However, a successful PCI procedure is only one part of the treatment; postoperative rehabilitation is equally crucial. Rehabilitation is not only about restoring cardiac function, but also affects patients' quality of life and the prevention of complications. Currently, traditional post-PCI rehabilitation training focuses on lower limb exercises, such as walking and jogging, but upper limb training is often neglected. Clinical practice has found that post-PCI patients often experience systemic movement disorders and impaired upper limb function. If upper limb training is neglected, patients may experience muscle atrophy, joint stiffness, decreased coordination and flexibility, affecting their ability to take care of themselves in daily life, and even increasing the burden on the heart, thus affecting the rehabilitation effect. In addition, some post-PCI patients have difficulty moving or are physically weak due to the impact of the surgery or their own physical conditions. For these patients, traditional rehabilitation training methods may not be suitable. They may not be able to complete walking, jogging, or other exercises independently, and may even feel powerless when performing simple lower limb exercises. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a cardiac rehabilitation exercise aid for patients after coronary artery disease PCI, solving the problem that traditional rehabilitation training focuses mainly on lower limb exercises and is not convenient for patients with limited mobility or physical weakness to perform active exercises.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cardiac rehabilitation exercise aid for patients after percutaneous coronary intervention (PCI), comprising a base, on which anti-slip pads, a handle, and a fixing post are provided. An electric lifting rod is provided in the fixing post, and the output end of the electric lifting rod is connected to a mounting base for adjusting the height of the mounting base. The mounting base contains a controller, a motor, a worm gear, and a shaft. A worm wheel meshing with the worm gear is provided on the shaft. A storage cavity is provided in the mounting base, and a tensioning device is provided in the storage cavity. The belt has a handle at its distal end for the patient to perform flexion and extension movements of the upper limb. The shaft passes through both ends of the mounting base and is connected to an external connecting rod. The connecting rod consists of a telescopic inner rod and an outer rod, with the outer rod sleeved on the outer end of the inner rod. The inner rod has several screw holes, and a fastening bolt passes through the outer rod and is screwed into the screw holes. The distal end of the outer rod is rotatably connected to a rotating seat, which has a slot for connecting with the handle or pedal. A second fastening bolt is screwed onto the rotating seat to fix the handle or pedal.

[0005] The beneficial effects of this invention are as follows: This invention can not only meet the movement needs of patients' upper and lower limbs, but also drive patients to move passively under the drive of a motor, thereby effectively improving the rehabilitation training effect.

[0010] As a further improvement to the above technical solution: both ends of the mounting base are provided with storage cavities for storing the tension belt, and the openings of the storage cavities at both ends are covered with cover plates. The bottom end of the cover plate is hinged to the mounting base, and the top end of the cover plate is connected to the mounting base with a snap fastener provided thereon.

[0011] The beneficial effects of this improvement are as follows: the cover plate facilitates the closure of the storage cavity opening for storing the resistance band. When the cover plate is opened, the resistance band can be taken out, making it easy for the patient to hold the handle and use the resistance band to perform flexion and extension exercises of the upper limbs.

[0012] To facilitate the adjustment of the length of the connecting rod:

[0013] As a further improvement to the above technical solution: the plurality of screw holes are equally spaced on one side along the length of the inner rod.

[0014] The beneficial effects of this improvement are as follows: by separating the external fastening bolt from the screw hole, the outer rod can be moved inward and outward to adjust the length of the connecting rod, thereby adjusting the distance of the handle or pedal to suit patients with different leg or arm lengths. After the length adjustment of the connecting rod is completed, simply screw the internal fastening bolt into the screw hole of the inner rod at the current position to fix the position of the outer rod.

[0019] As a further improvement to the above technical solution: a Velcro is provided on the outer wall of the far end of the fixing strap, and the Velcro is bonded to the adhesive layer of the outer wall of the fixing strap.

[0020] The beneficial effects of this improvement are as follows: after the patient's foot is on the pedal, simply wrap the fixing strap around the instep of the patient's foot at the fixing ring location, then pass the distal end of the fixing strap through the fixing ring and fold it back to tighten it, so that the Velcro is attached to the outer wall adhesive layer of the fixing strap in the appropriate position, which can fix the position of the patient's foot and facilitate the increase of the stability of the patient's foot when stepping on the pedal to perform lower limb movements.

[0021] To facilitate the setting and operation of various parameters:

[0022] As a further improvement to the above technical solution: an operation panel is provided on one side of the top of the mounting base, and the operation panel serves as a human-machine interface, connected to the controller via a signal line, for setting lifting and training parameters.

[0023] The beneficial effects of this improvement are: by setting up an operation panel, patients can easily press the operation buttons on the operation panel to set the lifting and lowering parameters and training parameters.

[0024] To facilitate receiving commands and controlling the operation of the electric lifting mast and motor:

[0025] As a further improvement to the above technical solution: the controller is connected to the electric lifting rod and the motor via wires, and is used to receive commands from the operation panel to control the lifting and lowering of the electric lifting rod and the driving of the motor.

[0026] The beneficial effects of this improvement are: after receiving instructions from the control panel, the controller can adjust the height of the mounting base by controlling the electric lifting rod according to the set parameters, and control the motor to drive the handle or pedal to rotate, thereby driving the patient's upper or lower limbs to perform passive training.

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figure 1-6As shown, a cardiac rehabilitation exercise aid for patients after percutaneous coronary intervention (PCI) includes a base 1, on which anti-slip pads 2, handles 3, and fixing posts 4 are provided. An electric lifting rod 5 is installed in the fixing post 4, and the output end of the electric lifting rod 5 is connected to a mounting base 6 for adjusting the height of the mounting base 6. The mounting base 6 contains a controller 7, a motor 8, a worm gear 9, and a shaft 10. A worm wheel 11 meshes with the worm gear 9 on the shaft 10. A storage cavity 12 is provided in the mounting base 6, and a tension band 13 is provided in the storage cavity 12. A pull handle 14 is provided at the distal end of the tension band 13 for the patient to perform upper limb flexion and extension exercises. The shaft 10 passes through both ends of the mounting base 6 and is connected to an external connecting rod, which is made of... The device consists of a retractable inner rod 16 and an outer rod 17, with the outer rod 17 fitted around the outer end of the inner rod 16. The inner rod 16 has several screw holes 18, and a fastening bolt 19 passes through the outer rod 17 and is screwed into the screw holes 18. A rotating seat 20 is rotatably connected to the distal end of the outer rod 17. The rotating seat 20 has a slot 28 for engaging with the connecting part of the handle 22 or pedal 23, and a second fastening bolt 21 is screwed onto the rotating seat 20 to fix the handle 22 or pedal 23. This invention not only meets the movement needs of the patient's upper and lower limbs but also, driven by the motor 8, enables passive movement, thereby effectively improving the rehabilitation training effect. The anti-slip pad 2 is located at the bottom of the base 1, while the handle 3 and the fixing post 4 are respectively located at... On both sides of the top of the base 1, the fixed columns 4 are vertically arranged, and the electric lifting rod 5 is vertically located in the fixed columns 4. The anti-slip rubber pads 2 can increase the friction coefficient and enhance the stability during placement and use. The handle 3 can facilitate displacement and conversion. With the electric lifting rod 5 in the fixed columns 4, when the electric lifting rod 5 is activated, it can drive the mounting base 6 to move up and down. The upper part of both ends of the mounting base 6 is provided with storage cavities 12 for storing the tension belt 13. The openings of the storage cavities 12 at both ends are covered with cover plates 15. The bottom end of the cover plate 15 is hinged to the mounting base 6, and the top end of the cover plate 15 is connected to the mounting base 6 by a buckle. The cover plate 15 allows for easy closure of the storage cavity 12 to store the tension band 13. After opening the cover plate 15, the tension band 13 can be removed, allowing the patient to easily grip the handle 14 and use the tension band 13 for upper limb flexion and extension movements. Several screw holes 18 are equidistantly located on one side of the inner rod 16 along its length. By externally screwing the fastening bolt 19 away from the screw holes 18, the outer rod 17 can be moved inwards and outwards to adjust the length of the connecting rod, thereby adjusting the distance of the handle 22 or pedal 23 to suit patients with different leg or arm lengths. After adjusting the length of the connecting rod, simply internally screw the fastening bolt 19 into the screw hole 18 of the inner rod 16 to fix the position of the outer rod 17.One end of the pedal 23 is provided with a fixing ring 24, and the other end of the pedal 23 is provided with a fixing strap 25 corresponding to the fixing ring 24. The fixing ring 24 facilitates the attachment of the fixing strap 25. The outer wall of the distal end of the fixing strap 25 is provided with Velcro 26, and the Velcro 26 is adhesively connected to the outer wall adhesive layer of the fixing strap 25. After the patient's foot is on the pedal 23, the fixing strap 25 is simply wrapped around the patient's instep at the fixing ring 24, and then the distal end of the fixing strap 25 is passed out of the fixing ring 24 and folded back to tighten it, so that the Velcro 26 is attached to the outer wall adhesive layer of the fixing strap 25 in the appropriate position. This can fix the position of the patient's foot and increase the stability of the patient's foot when stepping on the pedal 23 for lower limb movement. The mounting base An operation panel 27 is located on one side of the top of the device 6. This operation panel 27 serves as a human-machine interface and is connected to the controller 7 via a signal line. It is used to set lifting and training parameters. The operation panel 27 allows patients to easily press the buttons on it to set these parameters. The controller 7 is connected to the electric lifting rod 5 and the motor 8 via wires. It receives commands from the operation panel 27 and controls the lifting of the electric lifting rod 5 and the driving of the motor 8. After receiving commands from the operation panel 27, the controller 7 can adjust the height of the mounting base 6 according to the set parameters, and control the motor 8 to drive the handle 22 or pedal 23 to rotate, thus passively training the patient's upper or lower limbs.

[0037] The working principle of this utility model is as follows: During use, based on actual exercise needs, the base 1 is placed on the ground, bed, or table. The operating buttons on the control panel 27 are then pressed to set the lifting and training parameters. The instructions from the control panel are immediately received and processed by the controller 7. The controller 7, as the core component, precisely directs the electric lifting rod 5 to adjust its height, ensuring that the mounting base 6 and its auxiliary components reach a suitable height for the patient. After height adjustment, the patient can further adjust the length of the connecting rod according to their individual needs. By tightening or loosening the fastening bolt 19, the outer rod 17 can slide to the ideal position on the inner rod 16 and is fixed by screwing together the screw hole 18 and the fastening bolt 19. This makes the working distance of the handle 22 or pedal 23 more closely match the patient's actual needs, enhancing the targeted nature of rehabilitation exercises. For upper limb rehabilitation, patients can remove the resistance band 13 from the storage cavity 12, hold the handle 14, and perform stretching exercises. If motor assistance is required, simply install the handle 22 onto the connecting rod. The patient holds the handle 22, and the controller 7 will drive the motor 8 according to the preset training parameters. The motor 8 drives the shaft 10 and its auxiliary components through the meshing of the worm gear 9 and worm wheel 11, thereby achieving passive training of the upper limbs. For lower limb rehabilitation, similarly, the pedal 23 is installed on the connecting rod, and the patient places their foot on the pedal 23 and fixes it with the fixing ring 24, fixing strap 25, and Velcro 26. The controller 7 will control the motor 8 to drive the corresponding transmission mechanism according to the preset training parameters, causing the pedal 23 to move up and down, simulating walking or stepping movements, thus achieving the purpose of lower limb rehabilitation.
