Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training equipment, and in particular to rehabilitation equipment for patients after hematopoietic stem cell transplantation. Background Art

[0002] Hematopoietic stem cell transplantation is an important treatment method, widely used in the treatment of various blood diseases. However, postoperative patients often face physiological problems such as decreased muscle mass and weakened muscle strength. For example, in terms of breathing, since patients are bedridden for a long time during treatment, the strength of respiratory muscles decreases, and secretions are easily retained in the lungs or respiratory tract. At the same time, after hematopoietic stem cell transplantation, the patient himself is in an immunosuppressive state, which increases the probability of causing related complications such as lung infection.

[0003] Prior art, such as a respiratory muscle strength trainer with publication number CN217548926U, during use, a sealing ball is blown up through a breathing tube, and plug plates are set at different air holes to achieve targeted training for different groups of people. By placing the baffles at different positions in the breathing tube, the intensity of respiratory muscle training can be gradually increased. During rehabilitation training using the above-mentioned respiratory muscle strength trainer, patients cannot visually observe the dynamic changes of the respiratory muscle strength trainer with their eyes, cannot reflect the training effect of their own respiratory muscle strength, and are prone to lose interest in respiratory training, which leads to a slower recovery of their own respiratory muscles. Summary of the invention

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present invention belongs. "Include" or "comprises" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Inside", "outside", "upper", "lower", "far", "near", "front", "back", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0021] The drawings in the present invention are not drawn strictly according to the actual scale, and the specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only schematic diagrams of the structures.

[0022] The present invention provides a post-hematopoietic stem cell transplantation patient rehabilitation device, which includes a shell 1 and a breathing nozzle 2, wherein the breathing nozzle 2 is arranged outside the shell 1, and the shell 1 has a through hole 6-1. The post-hematopoietic stem cell transplantation patient rehabilitation device also includes: an elastic air bag 3, which is arranged inside the shell 1 and is connected to the breathing nozzle 2; a push rod 4, one end of which is connected to the outside of the elastic air bag 3, and the other end passes through the through hole 6-1 and penetrates to the outside of the shell 1; a movable plate 5, the edge of which is rotatably arranged on the upper surface of the shell 1, and the middle part of the movable plate 5 is rotatably connected to the end of the push rod 4 located outside the shell 1.

[0023] The breathing mouthpiece 2 is conical, with the larger end of the cone close to the patient's mouth. The elastic airbag 3 is made of rubber. The shell 1 is 20 cm long, 10 cm wide and 8 cm high. The entire training process is similar to the process of blowing a balloon. The patient blows air toward the breathing mouthpiece 2 to expand the elastic airbag 3. During the expansion of the elastic airbag 3, the push rod 4 pushes the movable plate 5 to rotate on the shell 1; on the contrary, when the patient exhales, the elastic airbag 3 shrinks and the movable plate 5 is reset.

[0024] The patient rehabilitation device after hematopoietic stem cell transplantation can intuitively see the rotation angle of the movable plate 5 during the patient's breathing exercise. The rotation angle range of the movable plate 5 is 0°-90°. The rotation angle of the movable plate 5 is judged to reflect the strength of the respiratory muscles. When the rotation angle of the movable plate 5 is large, it indicates that the patient's respiratory muscles are strong and the more gas is exhaled; when the rotation angle of the movable plate 5 is small, it indicates that the patient's respiratory muscles are weak and the less gas is exhaled. By observing the dynamic changes in the rotation angle of the movable plate 5, the patient can intuitively know the effect of his own exercise and the degree of recovery, which can increase the patient's interest in exercise. It is suitable for patients to conduct rehabilitation training in the early stage, thereby promoting the recovery of patients.

[0025] In this embodiment, a piston 6 is provided in the shell 1, and the piston 6 can contact the elastic airbag 3. The piston 6 and the shell 1 on the side away from the breathing nozzle 2 form a sealed cavity 7. The side wall of the shell 1 constituting the sealed cavity 7 is provided with a perforation. A spring 8 is provided in the sealed cavity 7, and the two ends of the spring 8 are respectively connected to the piston 6 and the inner wall of the shell 1 constituting the sealed cavity 7.

[0026] The piston 6 and the housing 1 in the sealed cavity 7 are provided with limiting grooves for placing the spring 8, which can prevent the spring 8 from falling off or falling off. The spring 8 is used to reset the piston 6. When the patient recovers to the middle stage of rehabilitation, the resistance of the elastic airbag 3 during its own expansion can no longer meet the patient's rehabilitation training requirements, so the above structure is designed.

[0027] The elastic airbag 3 contacts and pushes the piston 6 during the expansion process, and overcomes the elastic force of the spring 8 to increase the difficulty of the patient's breathing exercise, which can meet the exercise effect of the patient in the middle stage of rehabilitation.

When the patient recovers to the late stage of rehabilitation, the patient's lungs already have a certain degree of respiratory function. In order to fully achieve the lung function of a normal person, the above structure is designed.

[0030] When the patient is exercising breathing, the piston 6 squeezes the spring 8, and at this time the piston 6 pushes the air in the sealed chamber 7 to enter the elastic airbag 3 through the second ventilation tube 11, the bent tube 10, the first ventilation tube 9 and the first one-way valve 12 in sequence, overcoming the elastic force of the spring 8 while also overcoming the resistance when breaking through the threshold of the first one-way valve 12, so as to improve the exercise effect.

[0031] In this embodiment, an air pressure sensor 13 is provided on the inner wall of the elastic airbag 3, and a display is provided on the movable plate 5. The processor inside the display is electrically connected to the air pressure sensor 13.

[0034] In addition to exercising the lung function during exhalation, the patient can also exercise the lung function during inhalation. When inhaling, the lungs expand and the abdomen swells, which can make the abdomen push the air pump to inflate the hand airbag 17; when inhaling, the lungs and abdomen contract at the same time, which can make the abdomen pull the air pump to deflate the hand airbag 17. At the same time, the hand airbag 17 can be grasped with bare hands, and the upper limbs can be exercised in the process of opening and clenching the hands.

[0039] It is convenient to fix the waist belt 21 on the patient's abdomen so that the waist belt 21 can be closely attached to the patient's abdomen during the ups and downs of the patient's abdomen.

[0040] In this embodiment, the seat 14 is arranged on a base plate 23, and below the base plate 23 is a moving wheel with a locking function. The base plate 23 is provided with a slide groove 24, and a slider 25 is arranged in the slide groove 24. The slider 25 is provided with a pedal 26 for lower limb exercise, and the base plate 23 has a plurality of threaded holes, and the threaded holes are matched with nuts for limiting the movement of the slider 25; a rotating shaft 27 is rotatably arranged on the slider 25, and connecting rods 28 are fixedly connected at both ends of the rotating shaft 27.

[0041] The upper and rear ends of the pedals 26 are provided with baffles to prevent the feet from slipping. Loosen the nut, move the slider 25 to a suitable position, and tighten the nut again to prevent the slider 25 from moving. Then the pedals 26, the rotating shaft 27 and the connecting rod 28 are similar to the pedal part of a bicycle, and the cyclic exercise of the lower limbs is achieved like riding a bicycle.

[0042] In this embodiment, the seat 14 is provided with a leg support plate 29, and the leg support plate 29 and the backrest are both rotatably arranged on the seat 14, and two power components are arranged on the seat 14 to respectively control the rotation of the leg support plate 29 and the backrest, and the power components include: a motor 30 capable of maintaining torque, fixedly arranged on the seat 14; a driving gear, fixedly arranged on the output shaft of the motor 30; a driven gear 31, fixedly arranged on the leg support plate 29 or the backrest; a chain 32, which is sleeved and connected with the driving gear and the driven gear 31.
