Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation exercise equipment, and in particular relates to a rehabilitation exercise device after interventional cardiology treatment. Background Technology

[0002] Cardiology, or cardiovascular medicine, is a clinical department within the general internal medicine department of hospitals at all levels, established for the diagnosis and treatment of cardiovascular diseases. It treats conditions such as angina pectoris, hypertension, sudden cardiac death, arrhythmia, heart failure, premature beats, irregular heartbeats, myocardial infarction, cardiomyopathy, myocarditis, and acute myocardial infarction. Interventional cardiology is a novel diagnostic and treatment technique for cardiovascular diseases. Without open-chest surgery, guided by imaging methods, a catheter is inserted through a superficial blood vessel and, using specific instruments, is delivered to the lesion site. Specific cardiac catheterization techniques are then used to diagnose and treat heart disease. Following interventional cardiology treatment, patients require rehabilitation exercises to help them recover quickly. Rehabilitation devices can assist patients in these exercises.

[0003] Most existing rehabilitation exercise devices for post-cardiology treatment consist of a metal frame. When using them, patients lift the metal frame forward and lower it, then slowly follow up with their feet, repeating the above movements to achieve a certain training effect. However, existing rehabilitation exercise devices have limited functions, and patients cannot rest at any time during the exercise. If a patient is unable to continue walking due to physical discomfort after walking a long distance, the existing rehabilitation exercise device cannot assist the patient to return to the original position. The patient can only be carried by a person or sit in a wheelchair, which is quite inconvenient. Utility Model Content

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0015] This embodiment describes a rehabilitation exercise device for post-interventional cardiology treatment, such as... Figure 1 , Figure 5 and Figure 7 As shown, it includes two horizontally aligned handrails 4, which are aligned front to back and are mainly used to support the patient's hands during use. Each handrail 4 has a telescopic rod vertically fixed at both ends. The telescopic rod is an existing product and is common knowledge. Figure 3 As shown, the telescopic pole structure includes an inner rod 5 and an outer tube 6. The inner rod 5 is located inside the outer tube 6 and can move up and down along the inside of the outer tube 6 to extend and retract, thereby changing the overall length. It is widely used in daily life and various fields, most commonly as a telescopic antenna, clothes rack, or selfie stick. The telescopic pole is equipped with a locking device. In this embodiment, the locking device includes a spring. An installation groove is formed on the side wall of the inner rod 5, and an insert block is independently installed in the installation groove. The spring is located between the insert block and the bottom of the installation groove. The outer tube 6 has equally spaced through holes along its length for one end of the insert block to pass through. Figure 3 As shown, during the adjustment of the overall length of the telescopic rod, when the inner rod 5 moves and extends to a suitable length, the insert block is aligned with the corresponding through hole at that length, so that one end of the insert block is inserted into the through hole, thereby locking the inner rod 5 after it has moved and extended. Such locking devices are commonly used in daily life, such as on umbrellas and clothes racks. In this embodiment, the upper end of the inner rod 5 is fixed to the end of the handrail 4, so that by adjusting the length of all telescopic rods, the two handrails 4 can be raised and lowered to adapt to different usage conditions or to the height of different patients. A connecting rod 13 is horizontally fixed between the two telescopic rods on each handrail 4, such as... Figure 1 , Figure 3 and Figure 5As shown, a connecting rod 13 is horizontally fixed between the outer tubes 6 of the front and rear telescopic rods. The connecting rod 13 connects the outer tubes 6 on the left and right sides, so that the back plate 2 and the four telescopic rods are connected as a whole, which improves the firmness and stability of this rehabilitation exercise device. A back panel 2 is vertically installed between the two handrails 4, and the back panel 2 is fixed to two of the telescopic bars, such as... Figure 1 , Figure 3 and Figure 5 As shown, the back panel 2 is located between the two telescopic rods on the left side. The lower half of the back panel 2 is fixed to the outer tube 6 of the two telescopic rods. It is mainly used as a backrest. When this rehabilitation exercise device is used as a wheelchair, the back panel 2 can support the patient's back, making the patient more comfortable when sitting. Rollers 14 are installed at the lower ends of the two telescopic rods fixed to the back plate 2, such as... Figure 1 and Figure 5 As shown, the roller 14 is a common wheel on existing wheelchairs and is existing technology, so it will not be elaborated on here. In use, when this rehabilitation exercise device is pushed, the roller 14 can roll on its own. Of course, the patient can also push the steel ring on the roller 14 by hand to drive the roller 14 to roll. During the rehabilitation exercise, the roller 14 allows this rehabilitation exercise device to slide forward without fully lifting the upper limb, reducing the physical exertion of lifting the upper limb. It is especially suitable for patients with insufficient upper limb strength or weak coordination. The rolling propulsion of the roller 14 reduces the difficulty of use and can be adapted to more types of patients. The bottom of the other two telescopic rods is equipped with casters 12, such as... Figure 1 and Figure 5 As shown, the caster wheel 12 is existing technology and will not be elaborated on here. The caster wheel 12 is used to support the telescopic rod fixed thereto. The cooperation between the caster wheel 12 and the roller 14 makes it easier to move this rehabilitation exercise device. To elaborate further, such as Figure 5 and Figure 6 As shown, in this embodiment, a preferred embodiment includes a seat fabric 15, one end of which is fixed to the back panel 2; as Figure 7 As shown, one end of the seat fabric 15 is fixed to the lower end of the back panel 2; the seat fabric 15 is made of materials such as cotton, linen, silk, and synthetic fiber fabric, and the fabric has good flexibility, allowing it to bend and swing relatively freely; a support rod 3 is horizontally fixed to the other end of the seat fabric 15, and hooks 9 for hanging the support rod 3 are fixed to the two telescopic rods away from the back panel 2; as shown Figure 7 As shown, when the patient needs to rest while sitting, both ends of the support rod 3 are respectively secured in the hooks 9, making the seat fabric 15 horizontal. The hooks support and fix the support rod 3, and then the patient can sit on the seat fabric 15 to rest; Figure 3As shown in the figures, when a patient performs rehabilitation exercises, the two ends of the support rod 3 are respectively placed on the armrest rods 4, and the support rod 3 is supported and placed by the two armrest rods 4; the overall solution of the present invention forms a seating assembly that can swing up and down and is used for a patient to sit on; certainly, the seating assembly may also adopt a seat plate, one end of the seat plate is hinged on the back plate 2, so that the seat plate can swing up and down, a support plate is horizontally fixed on the back plate 2, when the seat plate swings to a horizontal state, it fits with the support plate, the seat plate is supported by the support plate, the patient can sit on the seat plate to rest, and when the patient performs rehabilitation exercises, the seat plate can swing upward to a vertical state, a U-shaped buckle is fixed on the swinging end of the seat plate, and the U-shaped buckle is clamped on the top of the back plate 2, thereby fixing the seat plate swinging to the vertical state.

[0016] Further description is given as follows Figure 1 , Figure 4 and Figure 6 shown, in this embodiment, a vertically arranged installation tube 7 is preferably included, and the installation tube 7 is fixed on the telescopic rod; in this embodiment, the installation tube 7 is vertically fixed on the outer side wall of the outer tube 6; a support rod 11 that can move up and down along the inside of the installation tube 7 is penetrated in the installation tube 7, as Figure 1 and Figure 5 shown, the support rod 11 can move up and down along the inside of the installation tube 7, the lower end of the support rod 11 will exceed the universal wheel 12 after passing out of the installation tube 7 for a certain distance, therefore, when the bottom of the support rod 11 fits the ground, the telescopic rod can be propped up by the support rod 11, so that the universal wheel 12 is separated from contact with the ground; a pull rod 10 is horizontally fixed on the support rod 11, a stroke groove which is in a "匚"-shaped structure and used for the pull rod 10 to move along the inside of the installation tube 7 is arranged on the tube wall of the installation tube 7; as Figure 1 , Figure 4 and Figure 6 shown, when the pull rod 10 is located in the horizontal section above the stroke groove, the entire support rod 11 is located in the installation tube 7, and when the pull rod 10 is located in the horizontal section below the stroke groove, the lower half section of the support rod 11 passes out of the installation tube 7; a tension spring 8 is connected to the pull rod 10, and the other end of the tension spring 8 is connected to the outer wall of the installation tube 7 between the two ends of the stroke groove; as Figure 1 , Figure 2 and Figure 5 shown, one end of the tension spring 8 is located in the middle of the tube wall between the two horizontal sections of the stroke groove, when the pull rod 10 moves into any one of the horizontal sections of the stroke groove, as Figure 2As shown, the tension spring 8 will pull the pull rod 10 towards the end of the travel groove to prevent the pull rod 10 from moving to the vertical section of the travel groove on its own, thus ensuring that the position of the support rod 11 is locked after movement. In use, when the patient needs rehabilitation exercises, the two telescopic rods equipped with casters 12 can be raised slightly, and then the support rod 11 can be pushed down by the pull rod 10, so that the lower half of the support rod 11 extends from the lower end of the mounting tube 7 until the end of the support rod 11 exceeds the caster 12, and the support rod 11 is pushed into the horizontal section of the travel groove. The tension spring 8 prevents the support rod 11 from leaving the horizontal section of the travel groove. Then, the two telescopic rods are lowered so that the bottom of each support rod 11 is in contact with the ground. The support rod 11 supports the telescopic rod, allowing the caster to move. 12 is detached from the ground; the friction between the bottom of the support rod 11 and the ground can prevent the rehabilitation exercise device from moving accidentally during use, thereby reducing the risk of accidental falls for patients; the overall solution constitutes a support assembly for contacting the ground and lifting the two casters 12 upwards off the ground; of course, the support assembly can also use electric push rods, with electric push rods vertically installed on the two telescopic rods of the casters 12, the telescopic ends of the electric push rods pointing vertically downwards, and the telescopic ends of the electric push rods extending downwards until they exceed the casters 12, at which point the telescopic ends of the electric push rods are in contact with the ground, and the telescopic rods are lifted up, allowing the casters 12 to detach from the ground. The friction between the telescopic ends of the electric push rods and the ground can prevent the rehabilitation exercise device from moving accidentally during use, thereby reducing the risk of accidental falls for patients.

[0017] The bottom of the support rod 11 is fixed with an anti-slip pad, which is made of natural rubber, thermoplastic rubber, silicone and other materials. The anti-slip pad can increase the friction between the support rod 11 and the ground, and can also prevent the ground from damaging the support rod 11, so as to ensure the service life of the support rod 11. Two telescopic rods away from the back panel 2 are hinged with footrests 16 for placing the patient's feet; as shown Figure 2 , Figure 5 and Figure 7 As shown, the two telescopic rods on the right are pivotally hinged to the outer tubes 6. A hinge seat is fixed on the telescopic rod. The pedal 16 is hinged to the hinge seat through a damping pivot, allowing the pedal 16 to swing up and down. The pedal 16 can swing upward to a vertical position and downward to a horizontal position. The damping pivot can lock the pedal 16 when it is swinging to a vertical position. When the patient needs rehabilitation exercises, swinging the pedal 16 to a vertical position can prevent the pedal 16 from obstructing the patient's feet. When the patient is weak and needs to sit, the pedal 16 can be swinged to a horizontal position, allowing the patient's feet to rest on the pedal 16, thus making the patient more comfortable when sitting. Two handles 1 are horizontally fixed on the back panel 2, such as Figure 1 and Figure 5As shown, two handles 1 are fixed to the back panel 2 with a gap between them. When the patient sits on this rehabilitation exercise device, medical staff and caregivers can hold the two handles 1 to facilitate pushing the rehabilitation exercise device.

[0018] In actual use, when a patient needs rehabilitation exercises after interventional cardiology treatment, the height of all telescopic rods can be adjusted vertically to allow the two handrails 4 to reach a suitable height. Then, the support rod 11 is pushed downwards via the pull rod 10, causing the lower half of the support rod 11 to extend from the lower end of the mounting tube 7 until the end of the support rod 11 exceeds the universal wheel 12, and the pull rod 10 is engaged in the horizontal section below the travel groove. Then, the two telescopic rods are lowered so that the bottom of each support rod 11 is in contact with the ground. The support rod 11 supports the telescopic rod, allowing the universal wheel 12 to lift off the ground. Figure 5 As shown, the patient's hands rest on the handrail 4, pushing the handrail 4 forward causes the roller 14 to roll forward, while the entire rehabilitation exercise device moves forward. The patient then slowly follows with their feet. When the patient's hands press on the handrail 4, the friction between the bottom of the support rod 11 and the ground prevents the rehabilitation exercise device from moving accidentally during use, reducing the risk of accidental falls. Repeating this action achieves a certain degree of auxiliary rehabilitation exercise effect. When the patient needs to rest, the two ends of the support rod 3 can be respectively secured to the two hooks 9, making the seat cloth 15 horizontal. Figure 7 As shown, the support rod 3 is supported and fixed by hooks, and the patient can then sit on the seat 15 to rest, allowing the patient to rest at any time when physically exhausted. When the patient is unable to continue walking due to physical discomfort, the two ends of the support rod 3 are respectively locked into the two hooks 9, making the seat 15 horizontal. Then, the support rod 11 is pulled upward by the pull rod 10, so that the support rod 11 is fully inserted into the mounting tube 7. The pull rod 10 is locked into the horizontal section on the upper side of the travel groove, so that all the casters 12 are in contact with the ground. The two pedals 16 swing to a horizontal position, and the patient sits on the seat 15 with both feet on the two pedals 16, so that the device unfolds into a wheelchair shape. The patient can push the steel ring on the roller 14 with their hands to drive the roller 14 to roll, so that the rehabilitation exercise device can be moved. Of course, medical staff or caregivers can also push the rehabilitation exercise device by holding the two handles 1. Therefore, when the patient is unable to continue walking due to physical discomfort, they can sit on the rehabilitation exercise device and be transferred by the rehabilitation exercise device.
