[0002] A common problem faced by patients who are bedridden for a long time is muscle degeneration, which is muscle atrophy and decreased physical strength due to lack of exercise.

[0003] Muscle atrophy primarily occurs because, when muscles are not used, the rate of protein synthesis decreases while the rate of breakdown increases, leading to a reduction in muscle mass. For bedridden patients, limited physical activity is a direct cause of muscle atrophy. Furthermore, bed rest can lead to a series of complications, such as pressure sores and deep vein thrombosis, further impacting the patient's recovery process and quality of life.

[0004] For the problem of muscle atrophy in bedridden patients, common solutions include physical therapy and passive movement. However, traditional physical therapy methods usually require specialized medical staff to perform, which consumes a lot of human and material resources; moreover, for some critically ill patients, frequent movement may bring additional risks.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The following is in conjunction with the appendix Figure 1-6To further illustrate this application, an embodiment of this application discloses a rehabilitation training bed.

[0030] Reference Figure 1 and Figure 2 As shown, this utility model provides a rehabilitation training bed, which includes a bed body 100, a chest expansion training device 300, a stretching training device 200, and a knee flexion training device 400.

[0031] Chest expansion training device 300: This device is symmetrically arranged on the longitudinal side walls of both sides of the bed 100, with one set on each side, to ensure that the patient's needs for simultaneous or independent training of both arms can be met during use. With this design, patients can perform effective chest muscle strengthening exercises in bed.

[0032] Stretching Exercise Device 200: Located at the head of the bed, it also has two sets, one for each of the patient's left and right arms. This device allows patients to perform arm flexion and stretching movements, which helps to strengthen upper limb strength, improve the flexibility of shoulder and back muscles, and relieve muscle stiffness caused by prolonged bed rest.

[0033] Knee flexion training device 400: Installed at the foot of the bed, it has two sets, one for each of the patient's legs. The device is designed with the specific characteristics of the knee and surrounding muscle groups in mind, enabling patients to perform safe and effective knee flexion exercises, thereby strengthening lower limb muscles, promoting blood circulation, and reducing the risk of thrombosis.

[0034] Reference Figure 1 and Figure 2 As shown, a headboard 120 and a footboard 110 are fixedly connected to the head and foot ends of the bed frame 100, respectively. Both the headboard 120 and the footboard 110 are fixedly and vertically connected to the top surface of the bed frame 100. Support legs 140 are fixedly connected to the four corners of the bottom surface of the bed frame 100.

[0035] Reference Figure 2 and Figure 4 As shown, the chest expansion training device 300 includes a support plate 331, a stretching weight assembly, and a positioning assembly.

[0036] The positioning component is fixedly installed on the side wall edge of the bed frame 100, ensuring the stability and reliability of the entire device. The support plate 331 is installed via the positioning component and can be rotated and adjusted about the length of the bed frame 100 as its axis for use or storage. Furthermore, it allows users to flexibly adjust the position of the support plate 331 along the length of the bed frame 100 according to their needs, thus accommodating patients of different heights.

[0037] The stretching weight-bearing component is installed on the bottom surface of the bed frame 100mm. This component is a key part for enabling personalized training intensity adjustments. By changing the weight or resistance settings in the stretching weight-bearing component, patients can gradually increase the training difficulty according to their own physical condition and rehabilitation progress. This modular design not only improves training effectiveness but also effectively avoids the risk of injury due to overtraining.

[0038] In practical use, the pull rod with the pull rope is wrapped around the end face edge of the support plate 331 and connected to the tensioning load-bearing component. The patient only needs to hold the pull rope with the pull rod to complete chest muscle strengthening training in bed, thereby promoting the recovery of cardiopulmonary function.

[0039] Reference Figure 3 and Figure 4 As shown, the positioning assembly includes a positioning base 310, a positioning shaft 320, a limiting block 340, and a limiting spring 350. These components work together to ensure that the support plate 331 can be stably and flexibly adjusted in position during use.

[0040] The positioning seat 310 is fixedly connected to the bottom surface of the bed frame 100, positioned near the headboard 120 to correspond to the position of the upper limbs and torso. The positioning seat 310 has a receiving groove 311 along the length of the bed frame 100, with an opening at its bottom for easy installation of other components. By fixing the positioning seat 310 near the headboard 120, the support plate 331 is ensured to be more ergonomic during operation, improving patient comfort and training effectiveness.

[0041] The positioning shaft 320 is fixedly connected to the receiving groove 311 of the positioning seat 310, and its axial direction is parallel to the length direction of the positioning seat 310. The support plate 331 is slidably disposed on the positioning shaft 320 and can be freely adjusted in position along the length direction of the positioning shaft 320. This allows the support plate 331 to be precisely adjusted in position according to different training needs, improving the flexibility and adaptability of the equipment.

[0042] The positioning base 310 has multiple slots 312 connected to the receiving groove 311 on its side wall. These slots 312 are evenly distributed along the length of the positioning base 310. When the support plate 331 is adjusted to a relative position along the positioning axis 320, it can rotate and lock into the corresponding slot 312 during rotation, preventing the support plate 331 from sliding along the axial direction of the positioning axis 320 during use. The design of multiple sets of slots 312 allows the support plate 331 to be locked in different positions to meet the needs of patients of different heights. The positioning seat 310 also has a limiting groove 313 communicating with the slot 312. The limiting groove 313 is connected by the side wall of the slot 312 and has an opening on the outer side wall of the positioning seat 310. The limiting block 340 is slidably disposed in the limiting groove 313 and partially extends out of the outer side wall of the positioning seat 310. The limiting block 340 also has a push block extending out of the side wall of the positioning seat 310. The limiting spring 350 is installed in the limiting groove 313, with one end abutting against the side wall of the limiting groove 313 and the other end abutting against the limiting block 340, for pushing the limiting block 340 out from the connection between the limiting groove 313 and the slot 312. The combination of the limiting block 340 and the limiting spring 350 ensures that the support plate 331 can be automatically locked after the position is adjusted, improving the reliability and stability of the system.

[0043] During use, the support plate 331 is rotated around the positioning shaft 320 into the corresponding slot 312. During this process, the push block of the limiting block 340 is first pushed, causing the limiting block 340 to compress the limiting spring 350 and retract into the limiting groove 313. Once the support plate 331 is rotated to its position, the pushing force on the limiting block 340 is released, and the limiting block 340 pops out under the action of the limiting spring 350, locking the support plate 331 into the slot 312, thus preventing it from tipping over during use. Furthermore, the rotated support plate 331 extends along the width of the bed 100, and its end face is equipped with a support bearing. A pull rope passes around the support bearing, providing torque in the arm extension direction for the patient to perform chest expansion exercises.

[0044] Reference Figure 4 and Figure 5 As shown, the tension load assembly includes a support base 360, a support shaft 370, a tension spring 390, and multiple load plates 380.

[0045] The support base 360 ​​is fixedly connected to the bottom surface of the bed 100, and has an opening in the bottom of the support base 360. The support shaft 370 is fixedly connected to the inside of the support base 360, and its length direction is perpendicular to the length direction of the positioning shaft 320. Multiple weight plates 380 are slidably mounted on the support shaft 370, allowing the user to freely adjust the position of the weight plates 380 according to training needs.

[0046] A tension spring 390 is sleeved on the support shaft 370, with one end abutting against the side wall of the support base 360 ​​near the positioning base 310, and the other end abutting against the weight plate 380. This arrangement allows the weight plate 380 to slide along the support shaft 370 when subjected to external force, and to return to its original position by the spring force after the external force is released. Furthermore, the application of the tension spring 390 not only increases the feeling of resistance during training.

[0047] Each weight plate 380 is fixedly connected to a handle, allowing patients to easily connect the pull ropes to different weight plates 380 according to the training intensity during use. By pulling different numbers of weight plates 380, the tension spring 390 is compressed, thereby changing the training intensity.

[0048] In practical use, patients can choose a suitable weight plate 380 for training according to their own needs. For example, in the initial rehabilitation stage, one weight plate 380 can be selected to enhance muscle strength; as the rehabilitation progresses, the training intensity can be increased by pulling more weight plates 380. The pull rope is connected to the weight plate 380 through the handle. When the pull rope is pulled, the weight plate 380 will move along the support axis 370 and compress the tension spring 390, generating corresponding resistance, thereby achieving effective chest expansion exercise training.

[0049] Reference Figure 4 and Figure 5 As shown, the stretching training device 200 includes a weight shaft 240, a weight spring 230, and at least two weight blocks 220.

[0050] The load-bearing shaft 240 is fixedly connected to the bottom surface of the bed 100 and is located between the support base 360 ​​and the positioning shaft 320. Load-bearing support blocks 210 for connecting the bed 100 are fixedly connected to both ends of the load-bearing shaft 240, and the axial direction of the load-bearing shaft 240 is parallel to the axial direction of the positioning shaft 320.

[0051] At least two weight blocks 220 are slidably mounted on the weight shaft 240, allowing for flexible adjustment of the number of weight blocks 220 used according to different training intensities. A weight spring 230 is fitted onto the weight shaft 240, with one end abutting against a weight support block 210 near the headboard 120 and the other end abutting against a weight block 220. This configuration provides dynamic resistance, making the training process more challenging and adaptable. The sliding arrangement of the weight blocks 220 allows users to select an appropriate load based on their individual abilities and training goals.

[0052] Tension bearings 130 are provided on the bottom surface of the connection end between the bed frame 100 and the headboard 120, and on the top surface of the headboard 120. These tension bearings 130 are designed to reduce friction, ensure smooth movement of the tension ropes, and improve training comfort and efficiency.

[0053] When stretching exercises are required, the pull rope connected to the lever passes sequentially around the headboard 120 and the stretch bearing 130 of the bed frame 100, and finally connects to the weight block 220. In this way, the patient can perform pull-up-like stretching exercises on the bed frame 100 by holding the lever. The well-designed path ensures smooth operation of the pull rope, and the adjustable resistance provided by the weight block 220 and springs makes the training process both safe and efficient, helping to strengthen upper limb strength and improve shoulder flexibility.

[0054] Reference Figure 2 and Figure 6 As shown, the knee flexion training device 400 includes a connecting rod 430, a weight block 420, and a connecting rope 410. The bed frame 100 has a through hole at its connection with the footboard 110. A connecting rod 430 is placed on the top surface of the bed frame 100 and connects to the weight block 420 and connecting rope 410 through this through hole. A collar 440 is provided on the connecting rod 430, specifically designed to be fitted around the patient's ankle. It is made of a soft and durable material to ensure that it will not cause discomfort or abrasion to the patient's skin during prolonged use. By securing the connecting rod 430 to the patient's ankle through the collar 440, the patient can overcome the weight of the weight block 420 through leg strength to perform knee flexion exercises.

[0055] The weight block 420 is positioned beneath the bed frame 100, its location carefully designed to provide appropriate resistance to help enhance muscle strength and joint flexibility. The connecting rod 430 is connected to the weight block 420 by a high-strength connecting rope 410, ensuring that it will not break or slip during use.

[0056] When patients need to perform knee flexion exercises, the loop 440 on the connecting rod 430 is first placed around the ankle. Then, the patient uses the strength of their legs to pull the connecting rod 430, overcoming the weight of the support block 420 to complete the knee flexion movement. This allows each knee flexion movement to effectively exercise the muscles on the front and back of the thigh, while improving the range of motion and stability of the knee joint. Furthermore, since the length and tension of the connecting rope 410 are adjustable, the training difficulty can be adjusted according to the different rehabilitation stages and individual abilities of each patient, further optimizing the rehabilitation effect.

[0057] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
