[0002] For long-term bedridden patients, they often face problems such as insufficient pulmonary ventilation function, muscle atrophy, and dyspnea. In this case, cardiopulmonary rehabilitation training through chest expansion exercises is relatively effective. Chest expansion exercises can promote the expansion of the chest cavity, enhance the strength of the respiratory muscles, and improve the gas exchange function of the lungs.

[0003] For example, in Chinese invention patent CN114367092B, an auxiliary chest expansion exercise cardiopulmonary rehabilitation training device is provided. Through the set auxiliary robotic arm and the friction drive mechanism with controllable torque, it can help the training personnel perform active or passive chest expansion exercises in bed, so as to help the bedridden training personnel improve their cardiopulmonary function, thereby increasing the blood oxygen saturation, alleviating the symptoms of chest tightness and shortness of breath of the training personnel, and significantly slowing down the process of heart failure.

[0004] However, in practical applications, we found that it also has certain deficiencies: The above-mentioned and traditional bed chest expansion exercise aids, although they can support chest expansion exercises, have relatively large restrictions on the amplitude of chest expansion exercises. Especially when the arms are extended backward during chest expansion exercises, due to the obstruction of the bed body, it is difficult for the patient's arms to be extended backward, and thus it is impossible to well simulate the real chest cavity expansion process, which easily leads to insufficient exercise and affects the rehabilitation effect.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1 - 5 , a cardiopulmonary rehabilitation trainer for assisting chest expansion exercises, including a bed board 1. As Figure 1 shown, two arm slots 2 are symmetrically opened on both sides of the bed board 1, and two arm support plates 3 are respectively movably arranged in the two arm slots 2 and can rotate around a specified virtual center. In this embodiment, the virtual center is the patient's shoulder joint. By allowing the arm support plate 3 to rotate around the shoulder joint, it can ensure that when the patient performs chest expansion exercises, the arm extension action can be carried out more naturally, avoiding the situation where the arms cannot be fully extended due to the limitation of the bed or equipment, thereby improving the effect of chest expansion.

[0023] As Figure 2 shown, a telescopic plate 4 is movably and telescopically arranged at the end of the arm support plate 3, and a handle 5 is fixedly installed at the end of the telescopic plate 4. When the patient lies on the bed board 1 and needs to perform chest expansion exercise training, straighten the arms, hold the two handles 5 with both hands, and then move the arms back and forth to close and open them.

[0024] As Figure 4 shown, a moving block 6 is fixedly installed at one end of the telescopic plate 4 away from the handle 5. The moving block 6 is slidably arranged in a moving groove opened in the arm support plate 3 and is connected to the inner side wall of the moving groove through a traction spring 7. Thus, the telescopic plate 4 is telescopic, can adapt to the arm lengths of different patients, can effectively avoid the discomfort during exercise caused by the differences in the heights or body types of patients, ensure that different patients can achieve the best comfort and effect when performing chest expansion exercises, and improve the universality of the equipment.

[0025] As Figure 2 shown, an arc-shaped cabinet 8 is provided at the bottom of the bed board 1, and the virtual center of the arc-shaped cabinet 8 coincides with the virtual center (shoulder joint position). As Figure 4 shown, an arc-shaped rod 9 is movably and telescopically arranged in the arc-shaped cabinet 8. The end of the arc-shaped rod 9 extends to the outside of the arc-shaped cabinet 8 and is fixedly connected to the arm support plate 3. The patient's arm moves the arm support plate 3 and the telescopic plate 4 together. When moving, the arc-shaped rod 9 is gradually pulled out in the arc-shaped cabinet 8. The movement of the arc-shaped rod 9 in the arc-shaped cabinet 8 plays a limiting role, so that the movement trajectories of the arm support plate 3 and the telescopic plate 4 just adapt to the movement trajectory of the patient's arm. Furthermore, it also makes the arm support plate 3 rotate around the shoulder joint.

[0026] In this embodiment, a gear 12 is meshed with the outer wall of the arc-shaped rod 9. The gear 12 is rotatably installed in the arc-shaped cabinet 8 through a rotating shaft. One end of the rotating shaft extends to the outside of the arc-shaped cabinet 8 and is connected to an electromagnetic damper 13, and the other end of the rotating shaft extends to the outside of the arc-shaped cabinet 8 and is connected to the output shaft of a motor 14. During active training, the electromagnetic damper 13 can provide damping for the rotation of the gear 12, and thus provide damping for the extraction of the arc-shaped rod 9. By providing adjustable resistance through the electromagnetic damper 13, the intensity of the chest expansion exercise can be gradually increased as the patient recovers, ensuring that the patient will not over-exercise during the rehabilitation process, thereby providing a safer and more effective training.

[0027] During passive training, the motor 14 can drive the arc-shaped rod 9 to actively extend, and thus the exercise intensity can be gradually increased according to the patient's rehabilitation progress, promoting the recovery of the upper limb and chest muscles and enhancing the body's exercise endurance and strength.

[0028] During actual training, the active training mode or the passive training mode can be selected according to the patient's needs.

[0029] Embodiment Two: Please refer to Figure 2 and Figure 3 . On the basis of Embodiment One, in this embodiment, a bottom groove 15 is further formed at the bottom of the bed board 1. An adjustment cabinet 16 is slidably installed up and down in the bottom groove 15. Two groups of connecting rods 19 are respectively movably arranged on both sides of the bottom of the adjustment cabinet 16, and the two groups of connecting rods 19 are respectively connected to the two arc-shaped cabinets 8. Specifically, a threaded rod 17 is rotatably installed inside the adjustment cabinet 16. Thread one and thread two with opposite helix directions are respectively formed on both sides of the outer wall of the threaded rod 17. Nuts 18 are screwed on the outer walls of thread one and thread two. The two groups of connecting rods 19 are respectively fixedly installed at the bottoms of the two nuts 18. In this embodiment, the threaded rod 17 can be driven to rotate by a motor. When the threaded rod 17 rotates, through thread one and thread two with opposite helix directions, the two nuts 18 can be made to approach or move away from each other. The two nuts 18 approaching or moving away from each other through the two groups of connecting rods 19 can enable the two arc-shaped cabinets 8 to approach or move away from each other, thereby adjusting their positions and distances.

[0030] The up and down movement of the adjustment cabinet 16 is realized by a cylinder 21. Specifically, a fixing plate 20 is fixedly installed in the bottom groove 15. A cylinder 21 is fixedly installed at the bottom of the fixing plate 20. The output shaft of the cylinder 21 is connected to the adjustment cabinet 16. Thus, when the cylinder 21 operates, the up and down movement of the adjustment cabinet 16 can be controlled. Thus, in this embodiment, according to the individual differences of patients, the positions of the two arc-shaped cabinets 8 can be freely adjusted by the motor and the cylinder 21, so that the virtual center position of the arc-shaped cabinet 8 just coincides with the position of the patient's shoulder joint, facilitating the patient to perform chest expansion exercises, effectively solving the problem that the chest expansion exercises cannot be accurately adapted due to the differences in the body shapes of patients, ensuring that each patient can carry out personalized rehabilitation training, and maximizing the improvement of the cardiopulmonary function recovery effect.

[0031] Embodiment Three: Please refer to Figure 7 , on the basis of Embodiment Two, in this embodiment, an arc-shaped piston 10 is fixedly connected to the other end of the arc-shaped rod 9. In addition, a positioning spring 11 is fixedly installed on the inner side wall of the arc-shaped cabinet 8, and the positioning spring 11 is not connected to the arc-shaped piston 10 and only plays a supporting role; In the initial state, the bearing arm plate 3 is horizontal, and the arc-shaped piston 10 is in the position as shown in Figure 7 . When performing chest expansion exercises, when the two arms are gradually closed, the arc-shaped piston 10 is pulled out; conversely, when the two arms are gradually abducted, the arc-shaped piston 10 gradually returns to its original position; further, when the two arms are extended backward, the positioning spring 11 will be compressed, thereby adapting to the change in the position of the bearing arm plate 3; after the training is over, under the supporting force of the positioning spring 11, the bearing arm plate 3 can return to the horizontal position, thereby ensuring the horizontality of the bed surface; this design not only ensures the stability during the movement process, but also helps the device to return to the initial state after the training, avoiding deformation or deviation of the device, ensuring that the patient always maintains a comfortable and safe posture during use, and also facilitating the next use.

[0032] In the present invention, as shown in Figure 7 , one side of the end of the arc-shaped cabinet 8 is connected through a through pipe 30, and a one-way intake valve is installed on the intake pipe 30; the other side of the end of the arc-shaped cabinet 8 is connected through a through pipe to an exhaust hose 29, and a one-way exhaust valve is installed on the exhaust hose 29. The end of the exhaust hose 29 is connected to the main air groove 27 opened on the bed board 1, and a plurality of exhaust grooves 28 are uniformly opened perpendicular to the main air groove 27. The main air groove 27 and the exhaust grooves 28 are roughly in the shape of a "rich" character. Through the design of the intake pipe 30 and the exhaust hose 29 and the use of one-way valves, the one-way control of the air flow can be achieved, ensuring the correct flow direction of the gas during chest expansion exercises, contributing to the air flow on the back, and improving the comfort of the patient.

[0033] Specifically, when the two arms gradually close, the arc-shaped piston 10 is pulled out. At this time, the arc-shaped cabinet 8 can inhale external air through the intake pipe 30; conversely, when the two arms gradually unfold, the arc-shaped piston 10 resets, and the air in the arc-shaped cabinet 8 is discharged through the exhaust hose 29 and then discharged from several exhaust grooves 28 via the main air groove 27. Through the flow of air in the main air groove 27 and the exhaust grooves 28, the air flow on the back of the bedridden patient can be accelerated, effectively reducing the problem of back skin compression caused by long-term bed rest, significantly reducing the incidence of bedsores, and enhancing the comfort of the patient.

[0034] Embodiment 4: On the basis of Embodiment 2 or Embodiment 3, in this embodiment, a transverse groove 22 is provided below the surface layer of the bed board 1. A vertical board is fixed in the middle of the transverse groove 22. Both sides of the vertical board are connected with a pulling pad 23 through an elastic band 25. Massage blocks 24 are evenly arranged on the top of the pulling pad 23, and the end of the pulling pad 23 is connected with the bearing arm board 3 through an elastic band 26. In this way, when the bearing arm board 3 rotates around the virtual center, the pulling pad 23 will also be pulled to move through the elastic band 26. When the pulling pad 23 moves, through the movement of the massage blocks 24, it can play a certain massage role on the back of the patient, further avoiding the occurrence of bedsores caused by long-term bed rest.

[0035] Therefore, in the present invention, while the chest expansion movement is realized through the bearing arm board 3, through mechanisms such as the pulling pad 23, the massage of the back can also be realized synchronously. This synchronous function not only improves the effect of the chest expansion movement, but also takes care of the comfort and skin health of the patient during the rehabilitation process, reducing skin damage and discomfort caused by long-term bed rest.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
