Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a medical respiratory pulmonary function recovery training assistive device. Background Technology

[0002] Most chronic lung diseases are incurable, such as COPD and pulmonary fibrosis. These diseases mostly progress chronically; COPD, for example, often spans decades from onset to end-stage, during which time patients' quality of life is severely affected. For instance, patients find it difficult to engage in long-distance activities, many suffer from muscle atrophy and decreased exercise tolerance due to prolonged bed rest, and their emotional and mental well-being is also greatly impacted, experiencing anxiety and mood swings.

[0003] Research and medical practice have proven that pulmonary function recovery training has benefits such as improving patients' quality of life, reducing disease flare-ups, and slowing disease progression. Pulmonary function recovery training is essentially exercise training, which includes endurance training (lower limb exercises, upper limb exercises), strength training, breathing training, and training of respiratory-related muscles.

[0004] Some patients are too ill to undergo lung function recovery training. Using a ventilator can generally extend the training time and intensity for these patients. However, many patients, due to their weak constitution and poor motor skills, often experience shortness of breath and irregular breathing rhythms during the initial stages of lung function recovery training, making it difficult to maintain proper breathing and hindering lung function recovery.

[0005] Diaphragmatic resistance training is a commonly used method for training respiratory muscles. In hospitals, it is usually done by placing a 1-2 kg sandbag on the patient's upper abdomen. However, because the patient's abdomen is moving during training, the sandbag is prone to slipping off without assistance, thus interfering with the patient's breathing training.

[0006] Currently, there are no relevant products or technologies that can solve the above problems. Summary of the Invention

[0067] In this embodiment, the ball joint 91 is made of neodymium magnet; the telescopic cylinder 51 is made of iron.

[0068] Embodiment 2 of a medical respiratory pulmonary function recovery training aid device provided by the present invention, see [link to embodiment]. Figure 3 , Figure 4 Based on the medical respiratory pulmonary function recovery training auxiliary equipment described in Embodiment 1 above, it further includes a power supply regulator 20, a worm gear stepper motor 40, a locking seat 70, an elastic tension member 80, a first pulley 3, a second pulley 5, a steel wire rope 4, a lifting plate 8, and a support belt 9.

[0069] The power supply regulator 20 is fixedly connected to the C-shaped part 11, and the power supply regulator 20 is electrically connected to the worm gear stepper motor 40.

[0070] The output shaft of the worm gear stepper motor 40 is connected to a crank 411, and the end of the crank 411 is connected to a crank pin 4111. A bearing is sleeved on the crank pin 4111, and the axis of the crank pin 4111 is parallel to the axis of the output shaft of the worm gear stepper motor 40. The worm gear stepper motor 40 is fixedly connected to the vertical rod 61.

[0071] The first pulley 3 and the second pulley 5 are respectively rotatably connected to one end of the horizontal bar 62, with the second pulley 5 being away from the vertical bar 61;

[0072] The lifting plate 8 is connected to the underside of the arc panel 92 by screws through its middle part, and the end of the lifting plate 8 is connected to the end of the support strap 9 by Velcro 7.

[0073] The horizontal bar 62 is provided with slide rails 622 on both sides;

[0074] See Figure 3 , Figure 4 , Figure 5 The elastic tension member 80 includes a mounting shell 83, a tension spring 82, and a snap-fit ​​ball 81. One end of the mounting shell 83 has an opening, and a partition 831 is provided inside. A second slider 832 is provided below it. One end of the tension spring 82 is connected to the inside of the mounting shell 83, and the other end is connected to the snap-fit ​​ball 81. The mounting shell 83 is close to the second pulley 5.

[0075] See Figure 3 , Figure 4 , Figure 6 , Figure 7 The snap-fit ​​seat 70 includes a snap-fit ​​seat body 71. The snap-fit ​​seat body 71 has a snap-fit ​​groove 72 on its upper surface, a connector head 73 for connecting the pull rope at the front, a groove 75 at the upper rear, and a first slider 74 at the bottom. The snap-fit ​​groove 72 snaps into the snap-fit ​​ball 81.

[0076] The first slider 74 and the second slider 832 are both slidably connected to the slide rail 622;

[0077] There are two steel wire ropes 4. One steel wire rope 4 passes around the first pulley 3 and is connected between the outside of the bearing and the connector 73. The other steel wire rope 4 passes around the second pulley 5 and is connected between the ball head rod 91 and the mounting shell 83.

[0078] In this embodiment, the connector 73 is a screw with a radial hole.

[0079] Before using this invention, the patient lies supine on the hospital bed. First, keep the worm gear screw lift 30 raised, then insert the C-shaped part 11 to the side of the patient's bed near the patient's upper abdomen, and then tighten the top screw 12 to fix the invention to the side of the patient's bed.

[0080] When this invention is used to assist patients in diaphragm resistance training, depending on the patient's physical condition, push one telescopic cylinder 51 to the right until it disengages from the telescopic cylinder hook 621 and continue rotating the elastic push rod 50 to a vertical position (for patients with good physical fitness, both elastic push rods 50 on both sides of the horizontal rod 62 can be directly rotated to a vertical position); attach the upper abdominal piece 90 to the T-shaped connecting groove 513 at the lower end of the telescopic cylinder 51 via the ball joint rod 91; rotate the worm gear and handle 31 until, after the patient exhales, the bottom of the arc panel 92 contacts the patient's upper abdomen, thus setting the pressure on the patient's upper abdomen and assisting the patient in diaphragm resistance training. See [link to relevant documentation]. Figure 1 , Figure 8 .

[0081] During training, the pressure on the upper abdomen can be adjusted at any time by turning the worm gear and rotating the handle 31 as needed. After training, turn the worm gear and rotating the handle 31 to the high position, and then turn the elastic push rod 50 clockwise until the telescopic cylinder 51 is engaged with the telescopic cylinder hook 621.

[0082] When this invention assists patients in performing bridge exercises in bed, see [link to relevant documentation]. Figure 3 , Figure 4 Connect the ball-head rod 91 on the abdominal support 90 to the right end of the steel wire rope 4, and connect the bottom of the arc panel 92 to the middle of the lifting plate 8 with screws; pass one end of the support strap 9 between the patient's waist and the bed sheet, turn the worm gear and rotate the handle 31 until the bottom of the lifting plate 8 contacts the patient's upper abdomen, and then connect both ends of the support strap 9 to the two ends of the lifting plate 8 respectively; turn on the switch 21 to start the worm gear stepper motor 40 to run, providing assistance for the patient to perform bridge exercise training on the bed.

[0083] When the worm gear stepper motor 40 starts operating, the worm gear output head 41 drives the crank 411 to rotate, which in turn drives the crank pin 4111 to rotate. As the crank pin 4111 drives the bearing 2, which is rotatably connected to it, to move away from the first pulley 3, the bearing 2 pulls the steel wire rope 4, which in turn pulls the locking seat 70. The locking seat 70 pulls the locking ball 81, which, through the tension spring 82, pulls the mounting shell 83. This, in turn, lifts the abdominal support 90 via the steel wire rope 4, ultimately lifting the patient's waist with the support belt 9. As the crank pin 4111 drives the bearing 2, which is rotatably connected to it, to move closer to the first pulley 3, the tension exerted by the worm gear stepper motor 40 on the steel wire rope 4 gradually decreases. This allows the support belt 9 to assist the patient's buttocks in gradually returning to the bed. During the continuous operation of the worm gear stepper motor 40, the above process can be repeated to assist the patient in continuous training.

[0084] When a control program for multiple stepper motor 42 operating modes is written into the controller of the power supply regulator 20 (i.e., controlling the number of times the stepper motor 42 operates at intervals, the interval time, the number of revolutions per revolution, and the rotational speed within each revolution; for example, to enable patients to train 3 sets, with each set having a 10-second interval, each set completing 10 bridge exercises combined with abdominal breathing within 1 minute, with each inhalation taking 2 seconds and each exhalation taking 4 seconds), the stepper motor 42 can be set to rotate half a revolution clockwise within 2 seconds, then complete the remaining half revolution within 4 seconds, and rotate 10 revolutions within 1 minute. Then, the stepper motor 42 can be controlled to stop rotating for 10 seconds before repeating the above pattern twice more. The technology for controlling the speed and start / stop of the stepper motor 42 is well known to those skilled in the art, and the technology has been widely applied in existing products. Currently, stepper motors 42 containing the required control programs can be directly customized from manufacturers according to control needs (this is a mature existing technology and will not be elaborated further). After executing the corresponding control program through the motor operation mode control key 22, patients can perform physical training under the guidance of a suitable recommended standard breathing training model (i.e., specific recommended data for breathing requirements as mentioned above), and maintain the correct abdominal breathing method during training to activate diaphragm muscle fibers, promote diaphragm contraction, and promote the recovery of lung function.

[0085] This invention is used to assist patients in performing appropriate abdominal breathing training during bridge exercise training. When the patient feels the lifting force of the support strap 9, they should exert force to lift their buttocks while inhaling. When the patient feels the lifting force of the support strap 9 decreasing, they should gradually relax their waist and buttocks while exhaling until their body is completely on the bed. This allows for the simultaneous completion of abdominal breathing training during bridge exercise training.

[0086] The present invention can adjust the auxiliary lifting force provided by the present invention by turning the worm gear rotation handle 31 to raise the crank frame 60 after the support strap 9 is connected to the lifting plate 8, or by increasing or decreasing the number of locking balls 81 locked into the slot 72, so as to meet the personalized training needs of patients with different physical fitness and training stages.

[0087] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
