Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment, specifically to a rehabilitation exercise device for cancer radiotherapy patients. Background Technology

[0002] Radiotherapy is a crucial treatment for malignant tumors and plays a vital role in clinical applications. However, while killing tumor cells, radiotherapy also causes damage to surrounding normal tissues, leading to a series of adverse reactions that severely impact patients' quality of life and recovery of bodily functions. For example, head and neck radiotherapy can cause difficulty opening the mouth, affecting eating and communication; pelvic radiotherapy may cause lower limb lymphedema, leading to mobility issues.

[0003] In addition, chronic fatigue is a common problem faced by patients after radiotherapy. Chronic fatigue is not simply physical tiredness, but rather a persistent impact on the patient's quality of life, leading to decreased physical function and poor mental state. Scientific and reasonable rehabilitation exercises can effectively prevent muscle atrophy and joint stiffness, promote blood circulation and lymphatic drainage, thereby reducing the adverse reactions caused by radiotherapy, helping patients recover physical function as quickly as possible, and improving their quality of life.

[0004] However, some cancer radiotherapy patients lack sufficient awareness of the importance of rehabilitation exercises. They often believe that their bodies are weak after radiotherapy and need rest and recuperation, worrying that exercise will increase the burden on their bodies and affect the recovery process, thus neglecting the positive effects of rehabilitation exercises. For ordinary patients, radiotherapy itself is already a considerable expense, and they simply cannot afford the cost of purchasing professional rehabilitation exercise equipment. Furthermore, continuous trips to the hospital for rehabilitation exercises also cause inconvenience to daily life. This leads to a lack of systematic and professional guidance during rehabilitation exercises, making it difficult for patients to master the correct exercise methods and intensity. This not only may prevent them from achieving the expected rehabilitation results, but improper exercise may even further aggravate physical damage.

[0005] Meanwhile, existing rehabilitation exercise equipment also has significant limitations. Its functions are relatively simple, typically targeting only a specific body part or function, and it cannot be flexibly adjusted to meet the diverse rehabilitation needs of cancer radiotherapy patients. Cancer radiotherapy patients have complex and varied physical conditions, and different parts and degrees of damage require different rehabilitation exercise methods and intensities. Therefore, this invention provides a rehabilitation exercise device for cancer radiotherapy patients to meet the exercise needs of different patients, improve the device's applicability, and ensure the exercise effect for different patients. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a rehabilitation exercise device for cancer radiotherapy patients, which meets the diverse exercise needs of different patients, improves the applicability of the device, and ensures the exercise effect for different patients.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a rehabilitation exercise device for patients undergoing radiotherapy for tumors, comprising a base, a support rod and a fixing frame fixedly connected to the base, a handle for the patient's hand to grip on the support rod, and a seat cushion for the patient to sit on the fixing frame; a first telescopic rod is rotatably coupled to the support rod, and the end of the first telescopic rod away from the support rod is fixedly connected to the handle.

[0008] The seat is equipped with a foot pedal assembly for patients to perform cycling training. The first telescopic rod is also connected to a first air tube and a second air tube. One end of the first air tube is connected to an insertion hole. The insertion hole is detachably connected to a mouthpiece for patients to blow air and a push bag assembly for pushing the patient's upper and lower jaws to move. The other end of the first air tube is connected to a practice hole for connecting an external balloon.

[0009] One end of the second trachea is connected to the insertion hole, and the first telescopic rod is equipped with a switching component for switching the connection between the first and second trachea and the insertion hole; the other end of the second trachea is connected to a leg exercise component for training the patient's legs.

[0010] Furthermore, the foot pedal assembly includes a second telescopic rod fixedly connected to the seat cushion. A pivot is provided between the second telescopic rod and the fixed frame. The pivot is rotatably engaged with the fixed frame. Both ends of the pivot are coaxially fixedly connected to a wheel, and a first foot pedal is fixedly connected to each wheel.

[0011] Furthermore, a rotating block is fixedly connected to the end of the first telescopic rod away from the handle, and the rotating block rotates in conjunction with the support rod; a practice block for attaching an external balloon is fixedly connected to the center of the rotating block, and the practice hole is opened at the top of the practice block;

[0012] The conversion assembly includes a moving groove that passes through the rotating block. The moving groove is in the shape of a quarter circle arc and is located between the first air pipe and the second air pipe. A switching plate that rotates and cooperates with the rotating block is provided in the moving groove.

[0013] When the switching plate moves to its highest point, it closes the first trachea; when the switching plate moves to its lowest point, it closes the second trachea.

[0014] Furthermore, the push bladder assembly includes a central shaft detachably connected to the insertion hole, a push bladder slidably fitted on the central shaft, and expansion plates fixedly connected to both the upper and lower sides of the push bladder. The expansion plate connected to the bottom of the push bladder is fixedly connected to the central shaft, and the expansion plate connected to the top of the push bladder is slidably fitted to the central shaft.

[0015] The central shaft is connected to a mating tube at one end near the first telescopic rod. One end of the mating tube is connected to the push bladder, and the other end of the mating tube is connected to the insertion hole.

[0016] The leg exercise component includes a slide groove inside the fixed frame, with both sides of the slide groove extending through the fixed frame. A slider slides inside the slide groove, and a second foot pedal is fixedly connected to both sides of the slider. The second foot pedal is located outside the fixed frame.

[0017] A sleeve is fixedly connected inside the slide groove. The end of the second air pipe away from the first telescopic rod is connected to the sleeve. A piston is slidably fitted inside the sleeve. A connecting rod is hinged between the piston and the slider. The connecting rod is clearance fitted with the slide groove.

[0018] Furthermore, a spring is fitted onto the connecting rod, with one end of the spring fixedly connected to the sleeve and the other end of the spring fixedly connected to the slider.

[0019] Furthermore, the support rod, the first telescopic rod, and the second telescopic rod all include a first rod and a second rod, which are slidably fitted together, and the diameter of the first rod is smaller than the diameter of the second rod;

[0020] The second rod has a threaded connection with a fixing pin. When the fixing pin abuts against the first rod, the first rod and the second rod are fixedly connected.

[0021] Furthermore, a collar is fixedly connected to one end of the fixing frame near the support rod. The collar is detachably connected to the support rod, and the bottom of the collar is parallel to the bottom of the base.

[0022] Furthermore, a standing area is provided on the side of the base near the support rod, and several friction marks are provided on the standing area.

[0023] Furthermore, a clamping seat is fixedly connected to the first telescopic rod, and the clamping seat has a slot for placing a display panel, which is used to play recommended guidance videos after tumor radiotherapy.

[0024] Furthermore, the length of the expansion piece is greater than the diameter of the propulsion bladder, and a groove is formed on the side of the expansion piece away from the first telescopic rod. The groove is located on the side of the expansion piece away from the propulsion bladder.

[0025] The above approach has the following beneficial effects:

[0026] 1. This solution uses a fixed frame to support the seat cushion, ensuring stability for patients during foot or leg exercises. It also provides installation space for the leg exercise component, allowing patients to push it with their feet to move the push bag component when opening their mouths. This allows patients to control the movement of the leg exercise component by adjusting the size of their mouth opening during exercise, providing convenience during use.

[0027] 2. In this solution, the mouthpiece and propulsion bag assembly, which can be detachably connected inside the insertion hole, can meet the needs of different patients for lung and head and neck muscle exercises. The detachable connection also meets the need for one patient per use, thereby reducing the risk of respiratory infection that may occur after different patients use it and improving the applicability of the device.

[0028] 3. In this design, the handle provides a support position for the patient's hands during device use, so as to support the patient when using the foot pedal component, leg exercise component and push bag component, thereby improving the support stability of the patient during use.

[0029] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0040] The following detailed description illustrates the specific implementation method:

[0041] As attached Figures 1 to 6 The image shows a rehabilitation exercise device for cancer radiotherapy patients, comprising a base 1, a support rod 2 and a fixing frame 11 fixedly connected to the base 1, a handle 32 for the patient's hand to grip on the support rod 2, and a seat cushion 6 for the patient to sit on the fixing frame 11; a first telescopic rod 3 is rotatably coupled to the support rod 2, and the end of the first telescopic rod 3 away from the support rod 2 is fixedly connected to the handle 32. A clamping seat 31 is fixedly connected to the first telescopic rod 3, and the clamping seat 31 has a slot for placing a display panel. In this embodiment, the display panel includes, but is not limited to, common mobile terminals, displays with video storage, and other electrical components. The display panel is used to play recommended guidance videos after cancer radiotherapy.

[0042] The seat 6 is provided with a foot pedal assembly for the patient to perform cycling training. The foot pedal assembly includes a second telescopic rod 61 fixedly connected to the seat 6. A pivot is provided between the second telescopic rod 61 and the fixed frame 11. The pivot is rotatably engaged with the fixed frame 11. Both ends of the pivot are coaxially fixedly connected to a wheel 62. The wheel 62 is existing technology and will not be described in detail in this embodiment. A first foot pedal 63 is fixedly connected to each wheel 62.

[0043] The first telescopic rod 3 is also connected to a first trachea 51 and a second trachea 52. One end of the first trachea 51 is connected to an insertion hole, into which a mouthpiece 8 for the patient to blow air and a push bag 4 for moving the patient's upper and lower jaws are detachably connected. The other end of the first trachea 51 is connected to a practice hole for connecting an external balloon. One end of the second trachea 52 is connected to the insertion hole, and the first telescopic rod 3 is provided with a switching component for switching the connection between the first trachea 51 and the second trachea 52 and the insertion hole. A rotating block 33 is fixedly connected to the end of the first telescopic rod 3 away from the handle 32, and the rotating block 33 rotates in cooperation with the support rod 2. A practice block 34 for attaching an external balloon is fixedly connected to the center of the rotating block 33, and a practice hole is opened at the top of the practice block 34.

[0044] The conversion assembly includes a movable groove 53 that passes through the rotating block 33. The movable groove 53 is in the shape of a quarter circle arc and is located between the first air pipe 51 and the second air pipe 52. A switching plate 5 is provided in the movable groove 53 to rotate and cooperate with the rotating block 33. When the switching plate 5 moves to the highest point, the switching plate 5 closes the first air pipe 51. When the switching plate 5 moves to the lowest point, the switching plate 5 closes the second air pipe 52.

[0045] The push bladder 4 assembly includes a central shaft 41 detachably connected to the insertion hole. The push bladder 4 is slidably fitted on the central shaft 41. The upper and lower sides of the push bladder 4 are fixedly connected to the expansion plates 42. The expansion plates 42 connected to the bottom of the push bladder 4 are fixedly connected to the central shaft 41, and the expansion plates 42 connected to the top of the push bladder 4 are slidably fitted to the central shaft 41. The end of the central shaft 41 near the first telescopic rod 3 is connected to a mating tube. One end of the mating tube is connected to the push bladder 4, and the other end of the mating tube is connected to the insertion hole.

[0046] The other end of the second trachea 52 is connected to a leg exercise component for training the patient's legs. The leg exercise component includes a slide groove 12 inside the fixation frame 11, with both sides of the slide groove 12 penetrating the fixation frame 11. A slider 13 is slidably fitted inside the slide groove 12, and a second foot pedal 7 is fixedly connected to both sides of the slider 13. The second foot pedal 7 is located outside the fixation frame 11. A sleeve 9 is fixedly connected inside the slide groove 12. The end of the second trachea 52 away from the first telescopic rod 3 is connected to the sleeve 9. A piston 91 is slidably fitted inside the sleeve 9. A connecting rod 92 is hinged between the piston 91 and the slider 13, and the connecting rod 92 is clearance-fitted with the slide groove 12.

[0047] The specific implementation process is as follows:

[0048] During the use of the foot pedal assembly, the seat cushion 6 is supported by the fixing frame 11, and the handle 32 provides a support position for the patient's hands. This ensures the stability of the patient during foot or leg exercises and also provides installation space for the leg exercise assembly. When the patient opens their mouth, they can use their feet to push the leg exercise assembly to move the push bag 4 assembly. This allows the patient to control the movement of the leg exercise assembly by using their feet according to the degree of mouth opening during the exercise, providing convenience during use.

[0049] Then, the patient's feet are placed on the first foot pedal 63, and the feet drive the first foot pedal 63 to rotate, simulating a natural cycling motion to perform aerobic exercise, thereby increasing lung capacity, improving oxygen utilization, and improving the decline in lung function indicators caused by lung radiotherapy.

[0050] At the same time, recommended instructional videos are played through the display panel to guide patients to exercise actively, reducing the need for guidance from medical staff, providing systematic and professional guidance, enabling patients to master the correct exercise methods and intensity, and ensuring the expected rehabilitation effect.

[0051] During device use, the switching plate 5 is rotated by the finger. When the switching plate 5 reaches its highest point, the first trachea 51 is closed, ensuring that the second trachea 52 is connected to the insertion hole. This allows the leg exercise component to move and control the movement of the push bag 4 component, enabling the patient to control the opening and closing of their jaw based on their own leg movement. When the switching plate 5 reaches its lowest point, it closes the second trachea 52, allowing the patient to practice blowing up external balloons to train lung function parameters.

[0052] Meanwhile, the detachable mouthpiece 8 and push bag 4 assembly inside the insertion hole meet the needs of different patients for lung exercise and head and neck muscle activity. The detachable connection also meets the need for one patient per device, reducing the risk of respiratory infection that may occur after different patients use the device, and improving the applicability of the device.

[0053] During the process of connecting the second trachea 52 to the propulsion bag 4 assembly and the leg exercise assembly using the conversion component, the second foot pedal 7 drives the slider 13 to move within the slide groove 12, causing the slider 13 to drive the piston 91 to reciprocate within the sleeve 9 via the connecting rod 92. Based on the compression and suction of the air within the sleeve 9 by the piston 91, the expansion and contraction of the propulsion bag 4 are controlled, causing the propulsion bag 4 to drive the opening plate 42 on one side to slide on the central axis 41. The change in the distance between the opening plates 42 is adjusted to control the opening of the patient's upper and lower jaws.

[0054] In another embodiment, a spring 14 is sleeved on the connecting rod 92, one end of the spring 14 is fixedly connected to the sleeve 9, and the other end of the spring 14 is fixedly connected to the slider 13.

[0055] The specific implementation process is as follows: the movement of the slider 13 is supported by the spring 14 to apply a reaction force to the patient's leg and apply resistance exercise to adjust the exercise intensity during the leg movement process; at the same time, during the movement of the slider 13, the compressed spring 14 is used to facilitate the rapid reset of the push slider 13, so as to drive the piston 91 to draw in the sleeve 9, so that the air in the push bladder 4 enters the sleeve 9, thereby driving the push bladder 4 to retract.

[0056] In another embodiment, the length of the spreading piece 42 is greater than the diameter of the push bladder 4, and a groove is formed on the side of the spreading piece 42 away from the first telescopic rod 3. The groove is located on the side of the spreading piece 42 away from the push bladder 4.

[0057] The specific implementation process is as follows: During the process of the patient's upper and lower jaws biting against the expansion piece 42, the groove on the expansion piece 42 provides space for the teeth to be placed, so as to ensure the biting stability of the push capsule 4 in the process of pushing the patient's upper and lower jaws to train the head and neck muscles. This facilitates the push capsule 4 component to drive the patient's upper and lower jaws to move, so as to train the difficulty of opening the mouth that is prone to occur after head and neck radiotherapy.

[0058] In another embodiment, the support rod 2, the first telescopic rod 3, and the second telescopic rod 61 all include a first rod and a second rod, which are slidably fitted together, and the diameter of the first rod is smaller than the diameter of the second rod; a fixing pin 21 is threaded onto the second rod, and when the fixing pin 21 abuts against the first rod, the first rod and the second rod are fixedly connected.

[0059] The specific implementation process is as follows: the fixing pin 21 is rotated on the second rod to adjust the force applied by the fixing pin 21 to the first rod. By loosening the fixing action of the fixing pin 21 on the first rod, the first rod slides on the second rod to adjust the extension distance of the first rod to meet the needs of patients with different body shapes. Then, the fixing pin 21 is used to abut the first rod, thereby improving the applicability of the device to different patients.

[0060] In some embodiments, a collar is fixedly connected to one end of the fixing frame 11 near the support rod 2. The collar is detachably connected to the support rod 2, and the bottom of the collar is parallel to the bottom of the base 1.

[0061] The specific implementation process is as follows: The fixing frame 11 and the support rod 2 are connected by a detachable collar to facilitate the disassembly of the device, reduce the space occupied when the device is not in use or when different individual functions are required, and thus facilitate the storage of the device.

[0062] In some embodiments, the base 1 has a standing area 81 on the side near the support rod 2, and the standing area 81 has a number of friction patterns.

[0063] The specific implementation process is as follows: For patients undergoing chest radiotherapy, the standing area 81 is used to guide the patient. The first telescopic rod 3 is driven towards the standing area 81 by the handle 32. The friction texture is used to increase the ground friction when standing, ensuring the stability of the patient when practicing blowing up external balloons alone.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
