Description

Technical Field

[0001] This invention relates to the field of training equipment, and in particular to a cardiac training device for cardiac rehabilitation in cardiology. Background Technology

[0002] Cardiology, also known as cardiology or cardiology, is a medical discipline that specializes in the study of heart or vascular diseases. Both cardiology and cardiac surgery treat diseases caused by the cardiovascular system or heart. Cardiology mainly uses drug therapy, but also includes interventional cardiology and non-invasive or minimally invasive surgeries such as coronary artery catheterization. Cardiac rehabilitation refers to targeted interventions, including rehabilitation assessment, exercise training, diet and behavior, to improve the function and structure of heart disease patients. Heart disease patients often use cardiac rehabilitation training equipment to exercise.

[0003] Existing cardiac training equipment mostly uses a single exercise method when exercising patients' lower limbs, resulting in a relatively monotonous effect of cardiac rehabilitation training. When patients exercise with a single exercise method for a long time, they are prone to fatigue and boredom, which affects the training effect. At the same time, existing cardiac training equipment is difficult to adjust the exercise intensity, making it difficult to meet the training needs of different patients and thus having poor practicality. Summary of the Invention

[0004] This invention provides a cardiac training device for cardiac rehabilitation in cardiology, which solves the technical problem that existing cardiac training devices mostly use a single exercise method when exercising the lower limbs of patients, resulting in a relatively simple effect of cardiac rehabilitation training and difficulty in adjusting the exercise intensity.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A cardiac rehabilitation training device for cardiology includes a training base with a cushion at the top. A rotating shaft is symmetrically arranged at one end of the training base, and a training housing is fitted onto the outer surface of the rotating shaft. A T-shaped groove is provided at one end of the training housing, and a fixing hole is provided on one side of the inner wall of the T-shaped groove. A caster wheel is provided at the bottom of the training housing. An adjustment component is fitted onto one end of the training housing to adjust the resistance when operating in conjunction with a foot pedal component. A foot pedal component is installed inside the cavity of the training housing to exercise the user's legs for cardiac training. A switching component is provided on one side of the training housing to switch between two training modes in conjunction with the foot pedal component.

[0007] Optionally, the adjustment assembly includes a screw, which is threaded onto the bottom edge of one side of the training box, and an adjustment disc is provided at one end of the screw.

[0008] Optionally, a base plate is provided at one end of the screw, a telescopic rod is provided at one end of the base plate, a pressure plate is provided at one end of the telescopic rod, and a locking block is provided at one end of the pressure plate. The number of locking blocks is set to two sets, and the two sets of locking blocks are symmetrically arranged on the inner wall of the training box.

[0009] Optionally, the foot pedal assembly includes a first side plate, which is slidably disposed on one side of the inner wall of the T-shaped groove. An opening is provided through the outer surface of the first side plate, and the number of the openings is set to two sets, which are symmetrically arranged on the outer surface of the first side plate.

[0010] Optionally, a connecting rod is provided at one end of the first side plate, a rotating base is provided at one end of the connecting rod, a foot pedal is provided at the top of the rotating base, and the number of foot pedals is set to two sets, which are arranged symmetrically.

[0011] Optionally, a second side plate is provided at one end of the first side plate, the second side plate is sleeved on the outer surface of the connecting rod, a spring is elastically provided at the center of the second side plate, one end of the spring is connected to the first side plate, and a fixing rod is provided on the inner wall of the second side plate, the outer surface of the fixing rod is slidably attached to the inner wall of the opening.

[0012] Optionally, the switching component includes a switching box, which is disposed at one end of the training box. The number of switching boxes is set to two sets, which are arranged symmetrically. One end of the switching box is provided with a slot, and one end of the switching box is provided with a through mounting slot.

[0013] Optionally, a telescopic rod two is elastically provided on one side of the inner wall of the mounting slot. The telescopic rod two is connected to the inner wall of the mounting slot. A wedge block one is provided at one end of the telescopic rod two. A wedge block two is provided on one side of the wedge block one. One end surface of the wedge block one is in contact with the wedge block two. A pressure plate is provided at one end of the wedge block two. One end of the wedge block two is connected to one end of the pressure plate. The pressure plate is nested in the inner wall of the training box. One end of the pressure plate is pressed against the second side plate.

[0014] Optionally, the number of the first wedge is set to two sets, and the two sets of the first wedge are arranged diagonally along the slotting direction.

[0015] Optionally, the number of the first wedge is set to two sets, and the two sets of the first wedge are arranged diagonally along the slotting direction, and the shape of the first wedge is set to "L".

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up an adjustment component, using a base plate, telescopic rod, and pressure plate, and using a screw to change the distance between the base plate and the pressure plate, the force required to push the telescopic rod through the pressure plate changes synchronously, thereby achieving the effect of real-time adjustment of the resistance of the foot pedal assembly. This achieves the purpose of adjusting the training intensity of the foot pedal assembly, meeting the different exercise needs of patients. The mechanism is simple and easy to maintain, while reducing the cost of use.

[0018] By incorporating a foot pedal assembly and utilizing the first and second side plates and a fixing rod, users can limit and unlock the foot pedal position using foot movements. Switching between two exercise modes is achieved by altering the foot pedal's operating state in conjunction with a switching component. The interaction between wedge one and wedge two allows the patient to trigger the foot pedal by applying force with their foot, causing the two sets of wedges to engage and limit the movement of the two training boxes. Combined with omnidirectional wheels, this facilitates switching between exercise modes. The simple mechanism allows patients to easily switch modes during exercise. The linkage between the foot pedal assembly and the switching component, along with the patient's foot movements, enables switching between the two exercise modes, preventing decreased interest from prolonged use of a single exercise mode and further ensuring the effectiveness of the training.

[0034] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a cardiac training device for cardiac rehabilitation in cardiology, including a training base 1, a cushion 2 at the top of the training base 1, a rotating shaft 3 symmetrically arranged at one end of the training base 1, a training box 4 fitted on the outer surface of the rotating shaft 3, a T-shaped groove 41 at one end of the training box 4, a fixing hole 42 on one side of the inner wall of the T-shaped groove 41, and casters 5 at the bottom of the training box 4; an adjustment component 6 fitted at one end of the training box 4, used to adjust the resistance when operating in conjunction with a foot pedal component 7; a foot pedal component 7 disposed inside the cavity of the training box 4, used to exercise the user's legs to achieve the effect of cardiac training; and a switching component 8 disposed on one side of the training box 4, used to perform two training modes in conjunction with the foot pedal component 7. Switching between training modes is achieved by adjusting the force generated when the foot pedal component 7 contacts the device via the adjustment component 6. This force acts as resistance to the movement of the foot pedal component 7, thereby adjusting the training intensity to meet different patient needs. When patients use the foot pedal component 7 for cardiac rehabilitation training, adjustments can be made in real time according to their individual needs, improving the overall applicability of the device. The linkage between the foot pedal component 7 and the switching component 8, coordinated with the patient's foot movements, enables switching between the two training modes of the foot pedal component 7. This prevents decreased patient interest from prolonged use of a single training method, further ensuring training effectiveness. Furthermore, patients can switch between training modes simply by moving their feet; the mechanism is simple, easy to operate, and practical.

[0035] like Figure 3 As shown, the adjustment component 6 includes a screw 61, which is threaded onto the bottom edge of one side of the training box 4. An adjustment disc 62 is located at one end of the screw 61, and a base plate 63 is located at the other end. A telescopic rod 64 is located at one end of the base plate 63, and a pressure plate 65 is located at one end of the telescopic rod 64. A locking block 66 is located at one end of the pressure plate 65. Two sets of locking blocks 66 are symmetrically arranged on the inner wall of the training box 4. Before exercising, the patient rotates the adjustment disc 62 according to their physical condition. The rotation of the adjustment disc 62 simultaneously drives the screw 61 to rotate at the bottom edge of one side of the training box 4. Under the action of the screw thread, the screw 61 rotates and presses against the base plate 63. Under the action of the locking block 66, the base plate 63 is pressed against the telescopic rod 64, and the telescopic rod 64 is compressed, which changes the distance between the base plate 63 and the pressure plate 65. At the same time, the force required to push the telescopic rod 64 through the pressure plate 65 also increases synchronously. By setting the base plate 63, the telescopic rod 64 and the pressure plate 65, and using the screw 61 to change the distance between the base plate 63 and the pressure plate 65, the force required to push the telescopic rod 64 through the pressure plate 65 changes synchronously, thereby achieving the effect of real-time adjustment of the resistance of the foot pedal assembly 7, thus achieving the purpose of adjusting the training intensity of the foot pedal assembly 7, meeting the different exercise needs of patients, and reducing the cost of use while keeping the mechanism simple and easy to maintain.

[0036] like Figure 4 As shown, the foot pedal assembly 7 includes a first side plate 71, which is slidably disposed on one side of the inner wall of the T-shaped groove 41. An opening 72 is provided through the outer surface of the first side plate 71, and the number of openings 72 is set to two sets, which are symmetrically arranged on the outer surface of the first side plate 71. A connecting rod 73 is provided at one end of the first side plate 71, and a rotating base 74 is provided at one end of the connecting rod 73. A foot pedal 75 is provided at the top of the rotating base 74, and the number of foot pedals 75 is set to two sets, which are symmetrically arranged. A second side plate 76 is provided at one end of the first side plate 71, and the second side plate 76 is sleeved on the outer surface of the connecting rod 73. A spring 77 is elastically provided at the center of the second side plate 76, and one end of the spring 77 is connected to the first side plate 71. A fixing rod 78 is provided on the inner wall of the second side plate 76, and the outer surface of the fixing rod 78 is in contact with the inner wall of the opening 72.

[0037] In this embodiment, after the adjustment component 6 is adjusted to the correct position, the patient sits on the cushion 2 at the top of the training base 1, placing their feet on the foot pedal 75. The user pushes the foot pedal 75 with their legs, and the force on the foot pedal 75 causes the first side plate 71 to slide within the T-groove 41 via the connecting rod 73. After the first side plate 71 slides into place, it comes into contact with the pressure plate 65. At this time, the patient continues to exert force with their legs, pushing the pressure plate 65 through the first side plate 71. The pressure plate 65 is then pressed against the telescopic rod 64, causing the telescopic rod 64 to retract. Similarly... When the patient's leg drives the foot pedal 75 to slide in the opposite direction, the pressure plate 65 returns to its original position under the action of the telescopic rod 64. This operation is repeated to achieve the exercise effect on the patient's legs. When the patient needs to switch exercise modes, the patient uses the force of their foot to drive the foot pedal 75 to slide to one side of the training box 4 in the horizontal direction. The foot pedal 75 drives the first side plate 71 to slide through the connecting rod 73. After the first side plate 71 is in place with the inner wall of the training box 4, the connecting rod 73 continues to be under force and pulls the second side plate 76 closer to the first side plate 71 through the spring 77. As the side panel 76 moves, it causes the fixing rod 78 to slide against the inner wall of the opening 72 and insert into the fixing hole 42. When the fixing rod 78 is inserted into the fixing hole 42, a locking mechanism is formed between the fixing rod 78 and the fixing hole 42, which in turn locks the foot pedal 75. At this point, the user cannot step on the foot pedal 75 by exerting force with their feet. When the user exerts force with their feet to slide the foot pedal 75 horizontally towards the training box 4, the fixing rod 78 locks into the fixing hole 42, and the user's legs are in an open position. When the legs are closed, the fixing rod 78 disengages from the fixing hole 42 under the action of the spring 77. As the user repeatedly closes and opens the legs, the fixing rod 78 and the fixing hole 42 repeatedly disengage and engage with the user's foot movements. By setting the first side plate 71, the second side plate 76 and the fixing rod 78, the user can limit and unlock the position of the foot pedal 75 by foot movements. By changing the running state of the foot pedal 75 and cooperating with the switching component 8, the switching between the two exercise modes can be realized. The mechanism is simple.

[0038] like Figure 5 and Figure 6As shown, the switching component 8 includes a switching box 81, which is disposed at one end of the training box 4. Two sets of switching boxes 81 are arranged symmetrically. One end of each switching box 81 has a slot 82, and a through mounting slot 83 is provided at one end. A telescopic rod 84 is elastically provided on one side of the inner wall of the mounting slot 83, connecting to the inner wall of the mounting slot 83. One end of the telescopic rod 84 has a wedge 85. A second wedge 86 is provided on one side of block 85. One end of the surface of the first wedge 85 is in contact with the second wedge 86. A pressure plate 87 is provided on one end of the second wedge 86. One end of the second wedge 86 is connected to one end of the pressure plate 87. The pressure plate 87 is nested in the inner wall of the training box 4. One end of the pressure plate 87 is pressed against the second side plate 76. The number of the first wedges 85 is set to two sets. The two sets of first wedges 85 are arranged diagonally along the direction of the slot 82. The shape of the first wedges 85 is set to "L".

[0039] In this embodiment, before the second side plate 76 slides, one end of the second side plate 76 abuts against the pressure plate 87. The pressure plate 87 is forced to make wedge 1 85 abut against wedge 2 86. The two sets of wedge 2 86 are forced to move closer to each other to form a locking effect. The two sets of training boxes 4 are in a locked state at this time. When the second side plate 76 slides, one end disengages from the pressure plate 87. Under the action of the telescopic rod 2 84, wedge 1 85 is forced to reset. At the same time as wedge 1 85 resets, it pushes the pressure plate 87 to slide, causing the two sets of diagonally arranged wedge 1 85 to move away from each other along the center line. At this time, the inner walls of the two sets of wedge 1 85 are no longer in contact, and the two sets of training boxes 4 are unlocked. With the cooperation of the rotating shaft 3 and the universal wheel 5, the patient can use his feet to drive the two sets of training boxes 4 to move towards the center line. Sliding along both sides of the body achieves a second exercise effect. Similarly, after the patient resets the two sets of training boxes 4 by using the foot pedal 75, the patient uses the foot pedal 75 to drive the second side plate 76 to contact and squeeze the pressure plate 87. The pressure plate 87, under force, drives the second wedge 86 to squeeze the first wedge 85. The two sets of first wedges 85 are brought closer to each other along the center line, so that the two sets of first wedges 85 form a mutual locking effect, which limits the two sets of training boxes 4. By setting the cooperation between the first wedge 85 and the second wedge 86, the patient can use the force of the foot to drive the foot pedal 75 to trigger the two sets of first wedges 85 to lock together, which limits the two sets of training boxes 4. At the same time, with the universal wheel 5, the exercise mode can be switched. The mechanism is simple and convenient for the patient to switch at any time during exercise.

[0040] The working principle of the cardiac training device for cardiac rehabilitation in cardiology provided by this invention is as follows:

[0041] Before exercising, the patient rotates the adjustment disc 62 according to their physical condition. As the adjustment disc 62 rotates, it drives the screw 61 to rotate at the bottom of one side of the training box 4. Under the action of the screw thread, the screw 61 rotates and presses the bottom plate 63. Under the action of the locking block 66, the bottom plate 63 is forced to press the telescopic rod 64. The telescopic rod 64 is forced to extend and retract, which changes the distance between the bottom plate 63 and the pressure plate 65. At the same time, the force required to push the telescopic rod 64 through the pressure plate 65 also increases synchronously.

[0042] After the adjustment component 6 is adjusted to the correct position, the patient sits on the cushion 2 at the top of the training base 1, placing their feet on the foot pedal 75. The user pushes the foot pedal 75 with their legs, and the force on the foot pedal 75 causes the first side plate 71 to slide within the T-groove 41 via the connecting rod 73. After the first side plate 71 slides into place, it makes contact with the pressure plate 65. At this time, the patient continues to exert force with their legs, pushing the pressure plate 65 through the first side plate 71. The pressure plate 65 is then pressed against the telescopic rod 64, causing the telescopic rod 64 to retract. Similarly, when the patient's legs push the foot pedal 75 in the opposite direction, the telescopic rod... Under the action of 64, the pressure plate 65 is reset. This operation is repeated to achieve the exercise effect on the patient's legs. When the patient needs to switch the exercise mode, the patient uses the force of the foot to drive the foot pedal 75 to slide to one side of the training box 4 in the horizontal direction. The foot pedal 75 drives the first side plate 71 to slide through the connecting rod 73. After the first side plate 71 is in place with the inner wall of the training box 4, the spring 77 is pulled by the force to pull the second side plate 76. While the second side plate 76 slides, it drives the fixing rod 78 through the inner wall of the opening 72. When the fixing rod 78 is inserted into the fixing hole 42, it forms a limit fixation on the foot pedal 75.

[0043] As the second side plate 76 slides, one end disengages from the pressure plate 87. Under the action of the telescopic rod 84, the wedge block 85 is forced to reset. As the wedge block 85 resets, it pushes the pressure plate 87 to slide, causing the two sets of diagonally arranged wedge blocks 85 to move away from each other along the center line. At this time, the inner walls of the two sets of wedge blocks 85 are no longer in contact, causing the two sets of training boxes 4 to open away from each other. With the cooperation of the rotating shaft 3 and the universal wheel 5, the patient can use their feet to push the two sets of training boxes 4 to slide to both sides of the body, achieving the second exercise effect. Similarly, after the patient uses the foot pedal 75 to push the two sets of training boxes 4 to reset, the patient uses the foot pedal 75 to push the second side plate 76 to contact and squeeze the pressure plate 87. The pressure plate 87 is forced to push the wedge block 86 to squeeze the wedge block 85. The two sets of wedge blocks 85 are forced to move closer to each other along the center line, so that the two sets of wedge blocks 85 form a mutual locking effect, which limits the two sets of training boxes 4.
