Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training technology, specifically a rehabilitation training device for heart failure patients. Background Technology

[0002] Heart failure, or HF for short, refers to a condition caused by impaired systolic and diastolic function of the heart. After rehabilitation treatment, HF patients need to engage in aerobic exercise to promote recovery. For example, in the patent application "CN212880793U" titled "A Rehabilitation Training Device for Heart Failure Patients," the foot and hand components include foot pedals and handles. The foot pedals are rotatably mounted in the middle of a connecting frame, while the handles are fixedly mounted at the head of the connecting frame. This structural design ensures stable training using the foot pedals, while the handles ensure balance and stability during training. However, this structure still has the following problems in actual use:

[0003] During the rehabilitation process of heart failure patients, the intensity of training required varies depending on the rehabilitation stage or the individual patient. Training with different intensities can have a better effect on the cure of heart failure. However, the above-mentioned structure uses the same training intensity, so it cannot be adapted to different patients to find the most suitable training intensity for each patient.

[0004] Therefore, we proposed that rehabilitation training equipment for heart failure patients can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a rehabilitation training device for heart failure patients, in order to solve the problem mentioned in the background art that the training intensity on the market is the same, and therefore it is impossible to make adaptive adjustments for different patients to find the most suitable training intensity for each patient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rehabilitation training device for heart failure patients, comprising a base plate and a hand training mechanism fixed to the upper surface of the base plate for training the arm;

[0007] It also includes: a support is welded and fixed to the upper end face of the base plate, and the upper end of the support is fixed to the seat, and the right end of the seat is connected to the backrest, while the left end of the seat is fixed to the connecting cylinder, and the connecting cylinder is rotatably connected to a rotating shaft, wherein the outer side of the rotating shaft is fixed to one end of the movable frame.

[0008] An adjustment mechanism is provided on the outside of the connecting cylinder, which adjusts the training intensity through friction between the friction block and the rotating shaft.

[0009] Preferably, the adjusting mechanism includes a threaded adjusting rod and a threaded sleeve, wherein the threaded adjusting rod is disposed on the upper surface of the front end of the connecting cylinder, and the lower end of the threaded adjusting rod extends into the interior of the connecting cylinder to form a threaded connection with the threaded sleeve, and the threaded sleeve is fixed to the connecting cylinder.

[0010] Preferably, the lower end of the threaded adjusting rod is rotatably connected to the upper end face of the arc plate, and a friction block is bonded to the lower end face of the arc plate, while the friction block is in contact with the rotating shaft.

[0011] Preferably, the movable frame is provided with a rotating rod inside, and both ends of the rotating rod are rotatably connected to the movable frame. Moreover, a pull rope is wrapped around the outside of one end of the rotating rod, and the other end of the pull rope extends out from the left side of the movable frame and the support and is fixed.

[0012] Preferably, a torsion spring is sleeved on the outer side of the upper end of the rotating rod, and a cam is fixed on the outer side of the rotating rod.

[0013] Preferably, the cams are provided in four sets, and the outermost end of the cams contacts the massage ball, while the massage ball is disposed inside the leg rest pad.

[0014] Preferably, the massage balls and cams are arranged in a one-to-one correspondence, and the leg rest is filled with sponge, and the leg rest is installed on the left side of the movable frame.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This rehabilitation training device for heart failure patients not only achieves intensity adjustment, allowing for adaptive adjustments based on different patients or different stages of rehabilitation, thus finding the most suitable training intensity for the patient and improving the rehabilitation training effect, but also massages the calves placed on the leg rest pad, thereby relieving leg muscles, preventing calf cramps during training, and providing comfort. The specific details are as follows:

[0016] (1) The friction generated between the rotating shaft and the friction block increases the rotational resistance of the rotating shaft, which in turn increases the resistance when the person's legs are lifted on the mobile frame, thus achieving the function of intensity adjustment. This allows for adaptive adjustments based on different patients or patients at different rehabilitation stages, thereby finding the most suitable training intensity for the patient and improving the patient's rehabilitation training effect.

[0017] Furthermore, the threaded adjusting rod and the threaded sleeve are threadedly connected, and the threaded sleeve is fixed to the connecting sleeve, so that when the threaded adjusting rod rotates, it will move downwards, which in turn causes the threaded adjusting rod to drive the arc plate connected to its lower end to move downwards together, so that the arc plate drives the friction block on its inner side to contact the rotating shaft.

[0018] The hand training facility allows patients to train their hands, thus diversifying the training and improving the rehabilitation effect. The activity frame allows for leg training, and the leg pads provide softness and improve comfort.

[0019] (2) Pull the lever by pulling the rope to rotate, which in turn causes the lever to rotate the cam together. After rotating to a certain angle, the cam will contact and squeeze the massage ball, causing the massage ball to push outward and massage the calf placed on the leg pad, thereby relieving leg muscles, preventing calf cramps during training, and providing comfort.

[0020] Furthermore, when the pull cord is in a relaxed state, the force of the torsion spring can drive the rotating rod to reverse. This reverse rotation not only drives the cam to squeeze the massage ball again to achieve a massage effect, but also allows the rotating rod to rewind the pull cord for the next use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 The present invention provides the following technical solution:

[0030] Example 1: To address the problem in existing technologies where the training intensity is uniform, making it impossible to make adaptive adjustments for different patients to find the most suitable training intensity, the following solution is disclosed: An adjustment mechanism is provided on the outer side of the connecting cylinder 6. The training intensity is adjusted through friction between the friction block 13 and the rotating shaft 9. The adjustment mechanism includes a threaded adjustment rod 10 and a threaded sleeve 11. The threaded adjustment rod 10 is located on the upper front surface of the connecting cylinder 6, and its lower end extends into the interior of the connecting cylinder 6 to form a threaded connection with the threaded sleeve 11. The threaded sleeve 11 is fixed to the connecting cylinder 6. The lower end of the threaded adjustment rod 10 is rotatably connected to the upper end face of the arc plate 12. The friction block 13 is adhered to the lower end face of the arc plate 12, and the friction block 13 is in contact with the rotating shaft 9.

[0031] Firstly, when the training intensity needs to be adjusted, simply rotate the threaded adjustment rod 10. Since the threaded adjustment rod 10 is threadedly connected to the threaded sleeve 11, and the threaded sleeve 11 is fixed to the connecting cylinder 6, the threaded adjustment rod 10 will move downwards when it rotates. This causes the threaded adjustment rod 10 to drive the arc plate 12 connected to its lower end downwards as well. This causes the arc plate 12 to drive the friction block 13 on its inner side to contact the rotating shaft 9. Through the friction generated between the rotating shaft 9 and the friction block 13, the rotational resistance of the rotating shaft 9 increases, which in turn increases the resistance when the person's legs are raised on the movable frame 7. This achieves the function of intensity adjustment, allowing for adaptive adjustments based on different patients or patients at different stages of rehabilitation, thereby finding the most suitable training intensity for the patient and improving the patient's rehabilitation training effect.

[0032] Example 2: Based on Example 1, a new basic program is added to diversify the training and improve the effectiveness of rehabilitation training. See details for further information. Figures 1-3The base plate 1 and the hand training mechanism 2 for training the arm are fixed on the upper surface of the base plate 1; it also includes: a support 3 is welded and fixed to the upper surface of the base plate 1, and the upper end of the support 3 is fixed to the seat 4, and the right end of the seat 4 is connected to the backrest 5, while the left end of the seat 4 is fixed to the connecting cylinder 6, and the connecting cylinder 6 is rotatably connected to the inside of the connecting cylinder 6, wherein the outer side of the rotating shaft 9 is fixed to one end of the movable frame 7.

[0033] During training, the patient simply sits on the chair 4, and the backrest 5 supports the patient's back, thereby improving comfort. At the same time, the hand training mechanism 2 allows the patient to train their hands, thus diversifying the training and improving the rehabilitation training effect. Furthermore, the movable frame 7 allows for leg training, and the leg pad 8 provides softness and improves comfort.

[0034] Example 3: Based on Example 1, a new basic program is added to relax leg muscles during training, prevent calf cramps, and thus provide comfort. See details for further information. Figure 6 The movable frame 7 has a rotating rod 15 inside, and both ends of the rotating rod 15 are rotatably connected to the movable frame 7. A pull rope 14 is wrapped around the outside of one end of the rotating rod 15, and the other end of the pull rope 14 extends out of the movable frame 7 and is fixed to the left side of the support 3. A torsion spring 16 is sleeved on the outer side of the upper end of the rotating rod 15. At the same time, a cam 17 is fixed on the outer side of the rotating rod 15. There are four sets of cams 17, and the outermost end of the cam 17 contacts the massage ball 18. The massage ball 18 is placed inside the leg rest pad 8. The massage ball 18 and the cam 17 are arranged in a one-to-one correspondence. The leg rest pad 8 is filled with sponge and is installed on the left side of the movable frame 7.

[0035] When the movable frame 7 rotates upward around the pivot 9, the pull rope 14 pulls the rotating rod 15 to rotate. The rotation of the rotating rod 15 causes the cam 17 to rotate as well. When the cam 17 rotates to a certain angle, it contacts and squeezes the massage ball 18, causing the massage ball 18 to push outward and massage the calf placed on the leg rest 8, thereby relieving leg muscles, preventing calf cramps during training, and providing comfort. At the same time, when the movable frame 7 rotates downward around the pivot 9, the pull rope 14 will be in a relaxed state. At this time, the elasticity of the torsion spring 16 will drive the rotating rod 15 to reverse. This reverse rotation of the rotating rod 15 not only drives the cam 17 to squeeze the massage ball 18 again to achieve a massage effect, but also allows the rotating rod 15 to rewind the pull rope 14 for the next use.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
