Description

Technical Field

[0001] The present invention specifically relates to a post-vascular intervention rehabilitation auxiliary device. Background Art

[0002] Vascular intervention, also known as intravascular interventional therapy, is a technique that uses interventional devices such as catheters and guidewires to enter the vascular system through a small skin incision to diagnose and treat lesions. Common vascular interventional surgeries include vascular dilation, vascular stent implantation, intravascular thrombectomy, and vascular embolization. Currently, after vascular intervention, patients need to undergo rehabilitation exercises so that they can return to normal life and work more quickly.

[0003] For example, the Chinese patent application number: 202310444271.5 discloses a nursing and rehabilitation device for cardiovascular patients. During exercise, the patient's foot steps down on the pedal to drive the first fixed rod to move downward along the limit hole. At this time, the elastic belt has a certain pulling force on the pedal. The patient needs to step on the pedal hard to resist the pulling force of the elastic belt to achieve the exercise effect on the patient's lower limbs. After the patient has exercised for a period of time, the number of elastic belts can be increased according to their physical condition to enhance the pulling force of the elastic belt, so as to adjust the pulling training intensity according to the different conditions of the patient, effectively improve the training effect, and benefit the patient's recovery.

[0004] Most of the existing post-vascular intervention rehabilitation assistive devices have simple structures. During exercise, if the foot accidentally slips off the pedal or the exercise needs to be terminated due to an accident, the pedal cannot be fixed in time, and the pedal rebounds easily causing harm to the user, reducing the safety of the device. Therefore, in view of the above technical problems, a post-vascular intervention rehabilitation assistive device is proposed. Summary of the invention

[0036] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0037] See also Figures 1 to 4 In one embodiment, a post-vascular intervention rehabilitation auxiliary device includes a seat 10 and an exercise mechanism. The exercise mechanism is symmetrically arranged on both sides of the seat 10, and the exercise mechanism includes a pedal 20, a resistance mechanism and a protection mechanism.

[0038] A placing plate 101 is tilted at one end of the seat 10, two sets of guide posts 1011 are oppositely arranged at the end of the placing plate 101 away from the seat 10, and the pedal 20 is slidably arranged on the guide posts 1011 along the length direction of the placing plate 101. The resistance mechanism connects the pedal 20 and the seat 10 to apply a thrust to the pedal 20 to move closer to the seat 10. The protection mechanism includes a pressure pad 30, a first spring 301, a locking rod 302 and a first transmission assembly. The pressure pad 30 can be slidably arranged at the top end of the pedal 20 along the thickness direction of the pedal 20. The first spring 301 connects the pressure pad 30 and the pedal 20 to apply a thrust to the pressure pad 30 away from the pedal 20. The locking rod 302 is slidably arranged at the bottom end of the pedal 20 along the width direction of the pedal 20. One side of the guide column 1011 has multiple groups of locking holes 1012 spaced apart along the length direction of the placement plate 101. The first transmission assembly connects the pressure pad 30 and the locking rod 302. The pressure pad 30 can move closer to or away from the pedal 20 and can drive the locking rod 302 to separate from the locking hole 1012 or pass through the locking hole 1012 through the first transmission assembly.

[0039] In the above embodiment, by sitting on the seat 10 and placing the forefoot and the heel on the pedal 20 and the pressure pad 30 respectively, during exercise, the pressure pad 30 is first pressed to move the pressure pad 30 close to the pedal 20, and the pressure pad 30 moves close to the pedal 20 so that the first spring 301 is compressed and contracts and drives the locking rod 302 to separate from the currently matched locking hole 1012 through the first transmission assembly. At this time, the pressure pad 30 and the pedal 20 are pressed at the same time to drive the pedal 20 to move away from the seat 10 to counteract the thrust of the resistance mechanism on the pedal 20 to move close to the seat 10. Thereby, the purpose of exercising the lower limbs is achieved. When the foot accidentally slips off the pedal 20 or the heel is lifted, the pressure on the pressure pad 30 disappears. At this time, the reaction force of the first spring 301 causes the pressure pad 30 to move away from the pedal 20 and drives the locking rod 302 through the first transmission component to pass through the currently matched locking hole 1012 to fix the pedal 20. Therefore, when the foot accidentally slips off the pedal 20 or the exercise needs to be terminated due to an accident, the pedal 20 can be fixed in time to prevent the pedal 20 from rebounding and causing harm to the user, thereby improving the safety of the device.

[0040] Specifically in the above embodiment, a through slot 201 is provided on the pedal 20, and the through slot 201 is slidably sleeved on the guide column 1011 in the opposite direction along the length of the placement plate 101. Multiple groups of anti-slip strips 202 are provided on the top of the pedal 20 and the pressure pad 30. The bottom end of the pressure pad 30 is threadedly connected with a guide shaft 306, and the guide shaft 306 can slide through the pedal 20 along the thickness direction of the pedal 20. The first spring 301 is sleeved on the guide shaft 306, and the two ends are respectively against the pedal 20 and the pressure pad 30. By providing the through slot 201 and the guide column 1011, the sliding stability of the pedal 20 can be improved, and by providing the anti-slip strip 202, the stability when stepping on the pedal 20 and the pressure pad 30 can be improved. The guide shaft 306 can guide the expansion and contraction of the first spring 301, which can increase the service life of the first spring 301. At the same time, the first spring 301 can be removed by removing the guide shaft 306, which is convenient for replacing the first spring 301.

[0041] See also Figure 3 and Figure 4 In one embodiment, the first transmission assembly includes a first lever 303 and a first guide block 304; a guide rod 305 is provided at the bottom end of the pressure pad 30, and the guide rod 305 can slide through the pedal 20 along the thickness direction of the pedal 20, the first lever 303 is provided at the bottom end of the guide rod 305, and the first guide block 304 can be slidably provided at the bottom end of the pedal 20 along the width direction of the pedal 20, a locking rod 302 is provided at one end of the first guide block 304, and a first lever groove 3041 is obliquely opened on the first guide block 304, and the first lever 303 is slidably provided in the first lever groove 3041.

[0042] In the above embodiment, the pressure pad 30 moves close to the pedal 20. At this time, the guide rod 305 drives the first lever 303 to move and squeeze the first groove 3041 to move the first guide block 304. The movement of the first guide block 304 can drive the locking rod 302 to move, so that the locking rod 302 is separated from the currently matched lock hole 1012. Conversely, the pressure pad 30 moves away from the pedal 20. At this time, the guide rod 305 drives the first lever 303 to move in the opposite direction and squeeze the first groove 3041 to move the first guide block 304 in the opposite direction. The reverse movement of the first guide block 304 can drive the locking rod 302 to move in the opposite direction, so that the locking rod 302 is inserted into the currently matched lock hole 1012, which is convenient for driving the locking rod 302 to separate from the lock hole 1012 or to be inserted into the lock hole 1012.

[0043] Specifically in the above embodiment, the bottom end of the pedal 20 is provided with a first T-shaped slot 203, and the top end of the first guide block 304 is provided with a first T-shaped block 3042, and the first T-shaped block 3042 can be slidably arranged in the first T-shaped slot 203 along the width direction of the pedal 20. The first T-shaped slot 203 and the first T-shaped block 3042 cooperate to improve the sliding stability of the first guide block 304.

[0044] See also Figures 1 to 3In one embodiment, the resistance mechanism includes a second guide block 40, a connecting rod 401, a resistance assembly and an adjusting member; the second guide block 40 is slidably arranged on one side of the seat plate 10 along the length direction of the seat plate 10, and the two ends of the connecting rod 401 are respectively hinged to the second guide block 40 and the pedal 20, and the pedal 20 moves away from the seat plate 10 to drive the second guide block 40 to move close to the placement plate 101. A plurality of resistance assemblies are arranged on one side of the seat plate 10 in a vertical direction, and the adjusting member is rotatably arranged on the second guide block 40. The rotating adjusting member can connect the plurality of resistance assemblies in sequence, and the resistance assembly is used to apply a thrust to the second guide block 40 away from the placement plate 101.

[0045] When the pedal 20 is stepped on and the pedal 20 is moved away from the seat board 10, the pedal 20 moves through the connecting rod 401 to drive the second guide block 40 to move closer to the placement board 101. At this time, the thrust applied by the resistance component to the second guide block 40 away from the placement board 101 can be converted into a thrust applied to the pedal 20 to move closer to the seat board 10, thereby facilitating resistance exercise by stepping on the pedal 20 to achieve the purpose of lower limb exercise. Moreover, multiple groups of resistance components are connected in sequence by rotating the adjusting member. It can be understood that the more resistance components are connected to the adjusting member, the greater the thrust applied by the resistance component to the second guide block 40 away from the placement board 101, and the greater the thrust applied to the pedal 20 close to the seat board 10. At this time, the greater the force required to move the pedal 20 away from the seat board 10, and conversely, the fewer resistance components are connected to the adjusting member, the smaller the force required to move the pedal 20 away from the seat board 10, which is convenient for users at different rehabilitation stages to use and improves the practicality of the device. Moreover, the number of connected resistance components can be adjusted by rotating the adjusting member, and the adjustment is convenient and labor-saving.

[0046] Specifically in the above embodiment, a second T-shaped slot 105 is provided on one side of the seat plate 10, and a second T-shaped block 405 is provided on one side of the second guide block 40. The second T-shaped block 405 can be slidably arranged in the second T-shaped slot 105 along the length direction of the seat plate 10. The cooperation between the second T-shaped slot 105 and the second T-shaped block 405 can improve the sliding stability of the second guide block 40.

[0047] On the basis of the above embodiment, further, the resistance assembly includes a resistance block 402 and a second spring 403; a plurality of groups of mounting grooves 102 are provided on one side of the seat plate 10 in the vertical direction, and a limiting shaft 1021 is provided in each of the plurality of mounting grooves 102; the resistance block 402 can be slidably provided in the mounting groove 102 along the length direction of the seat plate 10, and is sleeved on the limiting shaft 1021; the second spring 403 is sleeved on the limiting shaft 1021, and the two ends respectively abut against the resistance block 402 and the end of the mounting groove 102; the second spring 403 is used to apply a thrust to the resistance block 402 away from the placement plate 101. The adjusting member includes a connecting screw 404; the connecting screw 404 is vertically threadedly connected to the second guide block 40; a connecting hole 4021 is vertically provided on the resistance block 402, and the connecting screw 404 can be sequentially penetrated into the connecting holes 4021 on the plurality of groups of resistance blocks 402.

[0048] In the above embodiment, the connecting screw 404 is moved downward by rotating the connecting screw 404, and the connecting screw 404 moves downward to be inserted into the connecting hole 4021. At this time, the second spring 403 can apply a thrust to the second guide block 40 away from the placement plate 101, thereby applying a thrust to the pedal 20 to move closer to the seat plate 10, which is convenient for applying a thrust to the pedal 20 to move closer to the seat plate 10, and by continuing to rotate the connecting screw 404 to make the connecting screw 404 continue to move downward, the connecting screw 404 continues to move downward and can be inserted into the connecting holes 4021 in the multiple groups of resistance components in sequence, thereby increasing the number of groups of connected resistance components, conversely, the connecting screw 404 is rotated in the opposite direction to move the connecting screw 404 upward, and the connecting screw 404 moves upward to be separated from the connecting holes 4021 in the multiple groups of resistance components in sequence, thereby reducing the number of groups of connected resistance components.

[0049] See also Figure 2 , Figure 3 and Figure 5 In one embodiment, the seat plate 10 also includes a driving assembly; one end of the seat plate 10 is hingedly connected to one end of the placement plate 101 so that the placement plate 101 can rotate around the wide side axis of the seat plate 10, the driving assembly connects the seat plate 10 and the placement plate 101, and the adjusting driving assembly can drive the placement plate 101 to rotate, the connecting rod 401 includes a first connecting rod 4011, a second connecting rod 4013 and a fixed knob 4012, one end of the first connecting rod 4011 is hinged to the second guide block 40, and the other end is slidably penetrated by the second connecting rod 4013 along its length direction, the fixed knob 4012 is threadedly connected to the first connecting rod 4011, and rotating the fixed knob 4012 can make one end of the fixed knob 4012 abut against the second connecting rod 4013, and one end of the second connecting rod 4013 is hinged to the pedal 20.

[0050] In the above embodiment, the fixing knob 4012 is rotated to separate the fixing knob 4012 from the second connecting rod 4013, and then the placement plate 101 is driven to rotate by the driving assembly. The rotation of the placement plate 101 can drive the second connecting rod 4013 to move, and at the same time drive the pedal 20 to rotate to adjust the height of the pedal 20. When the height of the pedal 20 is adjusted, the fixing knob 4012 is rotated in the opposite direction to make the fixing knob 4012 abut against the second connecting rod 4013. When the height of the pedal 20 is adjusted, the thrust applied to the pedal 20 to move closer to the seat plate 10 remains unchanged. By adjusting the height of the pedal 20, the lifting height and the lower limb extension posture can be adjusted according to the user's needs, thereby improving the practicality and comfort of use of the device.

The armrests 104 are provided to facilitate the user to hold the hand, thereby ensuring the stability of the user sitting on the seat board 10, thereby improving the stability of the user when exercising.

[0059] The specific implementation of the above-mentioned post-vascular intervention rehabilitation auxiliary device is as follows:

[0060] When the pedal 20 is moved away from the seat 10, the second guide block 40 can be driven to move close to the placement plate 101 through the connecting rod 401. When the second guide block 40 is moved close to the placement plate 101, the resistance block 402 can be driven to move through the connecting screw 404, so that the second spring 403 is compressed and contracted, thereby forming resistance to the movement of the pedal 20, thereby achieving the purpose of lower limb exercise.

[0061] When the foot accidentally slips off the pedal 20 or the heel is lifted, the pressure on the pressure pad 30 disappears. At this time, the reaction force of the first spring 301 causes the pressure pad 30 to move away from the pedal 20, and causes the guide rod 305 to drive the first lever 303 to move in the opposite direction to squeeze the first lever groove 3041 to cause the first guide block 304 to move in the opposite direction. The reverse movement of the first guide block 304 can drive the locking rod 302 to move in the opposite direction, so that the locking rod 302 is inserted into the currently matched locking hole 1012 to fix the pedal 20. At this time, the reaction force of the second spring 403 cannot cause the pedal 20 to rebound. Therefore, when the foot accidentally slips off the pedal 20 or the exercise needs to be stopped due to an accident, the pedal 20 can be fixed in time to avoid the rebound of the pedal 20 to cause harm to the user, thereby improving the safety of the device.
