Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation devices, and particularly relates to a pediatric respiratory rehabilitation training device. Background Art

[0002] In the pediatric field, respiratory diseases have always been an important factor affecting the health of children. Common ones such as asthma, bronchitis, pneumonia, etc. not only have a high incidence rate among children, but may also have a long-term impact on the growth and development of children. With the in-depth study of medical research, the importance of respiratory rehabilitation training in improving the respiratory function of children and enhancing their quality of life has become increasingly prominent. Through effective respiratory rehabilitation training, the respiratory muscle strength of children can be enhanced, the pulmonary ventilation function can be improved, and the frequency and severity of respiratory diseases can be reduced.

[0003] The research on pediatric respiratory rehabilitation training devices in China has also gradually increased. Some universities, research institutions and hospitals have cooperated to carry out relevant technology research and development and clinical application research. On the basis of learning from foreign advanced technologies, China is also exploring a respiratory rehabilitation training model with Chinese characteristics, such as combining traditional Chinese breathing exercises to develop training methods suitable for children. In terms of device research and development, the working principle of existing respiratory training devices is usually to apply a certain resistance to the inhalation or exhalation process of children during respiratory training to achieve the purpose of training the lung strength of children.

[0004] When children use respiratory training devices for respiratory training, training compliance is an important factor affecting the training effect of children. Training compliance refers to the degree to which children follow the training plan formulated by medical staff in terms of training frequency, training duration, training action specifications, etc. It not only reflects the cooperation attitude of children towards training, but also reflects their behavior performance during the entire training process. Age is an important factor affecting training compliance. Young children often have limited cognitive abilities and are difficult to understand the importance of respiratory training. They are easily distracted and cry during training, resulting in poor compliance. For example, children aged 3 - 5 may lack patience with boring training and are difficult to complete the prescribed training content. A large number of clinical studies have shown that there is a significant positive correlation between training compliance and training effect. A respiratory training study on children with asthma found that children with high compliance had significant improvements in lung function indicators such as vital capacity and peak expiratory flow rate after a period of training, and the number of asthma attacks also decreased significantly. While children with low compliance had no obvious improvement in lung function and poor disease control effect. Another study grouped and compared children with different compliance levels and found that children with high compliance were more prominent in enhancing respiratory muscle strength and improving respiratory function coordination.

[0005] However, at present, the training modes of most respiratory rehabilitation training devices are relatively fixed, and the interactivity of the entire respiratory training device is poor, unable to meet the personalized needs of children with different ages, conditions, and physical conditions, resulting in certain limitations in the depth and breadth of their clinical applications. For example, for younger children, simple and boring training modes are difficult to stimulate their interest and enthusiasm, leading to poor training compliance of children.

[0016] Preferably, the brightness of the color-changing light strip is adjustable.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: For a pediatric respiratory rehabilitation training device of the present invention, when a child blows air, the gas drives the pneumatic fan to rotate, and the pneumatic fan drives the screw rod to rotate, thereby driving the slider to move along the axial direction of the ventilation pipe. The slider drives the human-shaped plate to move along the axial direction of the ventilation pipe from one end of the ventilation pipe to the other end. The movement distance of the human-shaped plate is proportional to the ventilation volume in the ventilation pipe. The vital capacity of the child can be intuitively understood through the movement amount of the human-shaped plate. And because the screw rod will drive the total link mechanism to act through the transmission mechanism when rotating, and the total link mechanism can simulate the movement of human legs. Combined with the human-shaped plate, it can simulate the movement of a person on the ventilation pipe, thereby enhancing the interest of the entire training device, preventing the child from being resistant during respiratory training.

[0024] By setting the slip ring and the spring, when the exhalation speed of the child cannot reach the air flow velocity required to drive the fan to rotate, under the action of the elastic force of the spring, the slip ring automatically resets the human-shaped plate through the pull rope, thereby enhancing the interactivity of the entire training device, and further enhancing the interest of the entire training device. The controller controls the color-changing light strip to change the displayed color, thereby changing the color of the scale plate. Since the pneumatic fan will also drive the human-shaped plate to move while driving the slip ring, when the movement distance of the human-shaped plate outside the ventilation pipe increases, the color displayed by the color-changing light strip on the scale plate also changes, so that the interactivity of the entire training device is better.

[0038] Such as Figures 1-6As shown in the figure, a pediatric respiratory rehabilitation training device provided by the present invention includes an air hood 101 and an air pipe 102. The air hood 101 is communicated with the air pipe 102, and further includes: a pneumatic fan 103, a first transmission shaft 104, a lead screw 105, a slider 106, a human-shaped plate 107 and a total linkage mechanism. The pneumatic fan 103 is arranged in the air pipe 102, and the pneumatic fan 103 is coaxially arranged with the air pipe 102; the first transmission shaft 104 is connected to the pneumatic fan 103, and the first transmission shaft 104 is rotatably connected in the air pipe 102; the lead screw 105 is rotatably connected to the side wall of the air pipe 102, the axial direction of the lead screw 105 is parallel to the axial direction of the air pipe 102, and the lead screw 105 is in tooth connection with the first transmission shaft 104; the slider 106 is provided with a threaded hole, the slider 106 is connected to the lead screw 105 through the threaded hole, and a chute parallel to the lead screw 105 is arranged on the side wall of the air pipe 102, and the slider 106 is slidably connected in the chute; the human-shaped plate 107 is arranged on the slider 106; the total linkage mechanism is arranged on the human-shaped plate 107, the total linkage mechanism is connected with a transmission mechanism 108, the transmission mechanism 108 is connected with the lead screw 105, and the total linkage mechanism is used for simulating the movement of human legs.

[0039] Now briefly describe the working principle of the above embodiment:

[0040] When the device is in use, the child buckles the air hood 101 on the mouth and then blows air. The air enters the air pipe 102 through the air hood 101 and then discharges from the air pipe 102. When the air passes through the air pipe 102, the air drives the pneumatic fan 103 to rotate. The pneumatic fan 103 drives the first transmission shaft 104 to rotate, and the first transmission shaft 104 drives the lead screw 105 to rotate. Since the axial direction of the lead screw 105 is parallel to the axial direction of the air pipe 102, and the slider 106 is connected to the lead screw 105 through the threaded hole, the lead screw 105 will drive the slider 106 to move along the axial direction of the air pipe 102 when rotating. At the same time, the slider 106 slides in the chute on the side wall of the air pipe 102. Under the guidance of the chute, the smoothness of the movement of the slider 106 can be ensured. Driven by the slider 106, the human-shaped plate 107 moves along the axial direction of the air pipe 102 from one end of the air pipe 102 to the other end. The movement distance of the human-shaped plate 107 is proportional to the ventilation volume in the air pipe 102. Therefore, the vital capacity of the child can be intuitively understood through the movement amount of the human-shaped plate 107. And since the lead screw 105 will drive the total linkage mechanism to act through the transmission mechanism 108 when rotating, and the total linkage mechanism can simulate the movement of human legs. Combined with the human-shaped plate 107, it can simulate the movement of a person on the air pipe 102, thereby enhancing the interest of the entire training device.

[0041] The pediatric respiratory rehabilitation training device of the present invention can intuitively reflect the vital capacity of children during respiratory training, and can simulate the movement of a person on the ventilation pipe 102, enhancing the fun of the entire training device and preventing children from being resistant during respiratory training.

[0042] On the basis of the above embodiment, in order to enhance the interactivity of the entire training device, thereby further enhancing the fun of the entire training device.

[0043] As Figures 2-4 shown, wherein, the first transmission shaft 104 is engaged with a second transmission shaft 202, the second transmission shaft 202 is rotatably connected to the side wall of the ventilation pipe 102, the second transmission shaft 202 is engaged with the lead screw 105, a reel 203 is provided on the second transmission shaft 202, a pull rope 204 is wound on the reel 203, a sliding ring 205 is slidably connected to the inner cavity of the ventilation pipe 102 along its axial direction, the pull rope 204 is connected to the sliding ring 205, and a spring 201 is further provided in the inner cavity of the ventilation pipe 102, the spring 201 abuts against the sliding ring 205, and the spring 201 is used to apply an elastic force to the sliding ring 205 away from the reel 203. When the pneumatic fan 103 rotates, the reel 203 winds the pull rope 204.

[0044] When the pneumatic fan 103 drives the first transmission shaft 104 to rotate, the first transmission shaft 104 drives the second transmission shaft 202 engaged therewith to rotate, the second transmission shaft 202 drives the lead screw 105 to rotate, thereby driving the humanoid plate 107 to move. At the same time, the second transmission shaft 202 drives the reel 203 thereon to rotate. When the reel 203 rotates, it will wind the pull rope 204. The pull rope 204 pulls the sliding ring 205, and the sliding ring 205 moves in the ventilation pipe 102 along the axial direction of the ventilation pipe 102 towards the side close to the reel 203, thereby squeezing the spring 201 in the inner cavity of the ventilation pipe 102. When the spring 201 is squeezed, it will apply a reverse elastic force to the sliding ring 205, thereby hindering the rotation of the reel 203 to hinder the rotation of the pneumatic fan 103. At this time, if a child wants to move the humanoid plate 107, he must increase the exhalation rate. By increasing the exhalation rate, the child can exercise his own lung strength. And when the exhalation speed of the child cannot reach the air flow rate required to drive the pneumatic fan 103 to rotate, under the action of the elastic force of the spring 201, the humanoid plate 107 automatically resets, thereby enhancing the interactivity of the entire training device and further enhancing the fun of the entire training device.

[0045] As a preferred solution, as Figures 2-4 Figure 1 and Figure 6As shown in the figure, a pressure sensor 301 is further provided in the inner cavity of the ventilation pipe 102. One end of the spring 201 away from the slip ring 205 abuts against the pressure sensor 301. The pressure sensor 301 is used to detect the elastic force applied by the spring 201 to it. The pressure sensor 301 is electrically connected to a controller. A scale plate 303 is provided on the arm plate of the humanoid plate 107. A color-changing light strip 302 is provided on the scale plate 303. The color-changing light strip 302 is electrically connected to the controller. The controller controls the color displayed by the color-changing light strip 302 according to the elastic force detected by the pressure sensor 301. By setting the pressure sensor 301, under the drive of the pneumatic fan 103, the slip ring 205 moves towards one end close to the reel 203, thereby squeezing the spring 201. When the extrusion force received by the spring 201 increases, the elastic force detected by the pressure sensor 301 increases. At this time, the controller controls the color-changing light strip 302 to change the displayed color, thereby changing the color of the scale plate 303. Since the pneumatic fan 103 also drives the humanoid plate 107 to move while driving the slip ring 205 to move, when the moving distance of the humanoid plate 107 outside the ventilation pipe 102 increases, the color displayed by the color-changing light strip 302 on the scale plate 303 also changes, so that the interactivity of the entire training device is better.

[0046] As a preferred solution, as Figure 1 and Figure 2 shown in the figure, the brightness of the color-changing light strip 302 is adjustable. The controller controls the brightness of the color-changing light strip 302 according to the change rate of the elastic force detected by the pressure sensor 301. When the change rate of the elastic force is higher, the brightness of the color-changing light strip 302 is greater. When the child is performing breathing training, the higher the exhalation rate of the child, the faster the rotation speed of the pneumatic fan 103. Therefore, the change rate of the elastic force detected by the pressure sensor 301 is also higher, and the brightness of the color-changing light strip 302 is also greater, so as to form a positive feedback to the child and increase the fun of the entire device.

[0047] As a preferred solution, as Figures 2-4As shown in the figure, the transmission mechanism 108 includes a gear 401, a third transmission shaft 402, a first crank 403 and a second crank 404. The gear 401 is in tooth engagement with the lead screw 105. The gear 401 is used to simulate the wheel of the unicycle, and the slider 106 is used to simulate the frame of the unicycle. The third transmission shaft 402 is connected to the gear 401, and the third transmission shaft 402 is rotatably connected to the slider 106. The first crank 403 and the second crank 404 are arranged at both ends of the third transmission shaft 402. Both the first crank 403 and the second crank 404 are arranged along the radial direction of the third transmission shaft 402. The first crank 403 is used to simulate one crank of the unicycle, and the second crank 404 is used to simulate the other crank of the unicycle. While the lead screw 105 drives the slider 106 to move, it will also drive the gear 401 to rotate. When the gear 401 rotates, it will drive the first crank 403 and the second crank 404 to rotate. Under the drive of the first crank 403 and the second crank 404, the total connecting rod mechanism moves. Since the slider 106 simulates the frame of the unicycle, the gear 401 simulates the wheel of the unicycle, the first crank 403 is used to simulate one crank of the unicycle, the second crank 404 is used to simulate the other crank of the unicycle, combined with the total connecting rod mechanism to simulate the movement of the human leg and the humanoid plate 107. Therefore, when the slider 106 slides on the ventilation pipe 102, the whole part will simulate a little person riding a unicycle, thereby further enhancing the interest of the whole training device and improving the interest of the child in performing breathing training.

[0048] As a preferred solution, as Figures 1-4 shown in the figure, the total connecting rod mechanism includes two groups of branch connecting rod mechanisms. The two groups of branch connecting rod mechanisms are respectively arranged on both sides of the humanoid plate 107. The two groups of branch connecting rod mechanisms respectively simulate the movement of the left leg and the right leg of a person. The two groups of branch connecting rod mechanisms have the same structure and both include a first connecting rod 501 and a second connecting rod 502. One end of the first connecting rod 501 is hinged to the humanoid plate 107, the other end of the first connecting rod 501 is hinged to one end of the second connecting rod 502, and the other end of the second connecting rod 502 is hinged to the first crank 403 or the second crank 404. When the first crank 403 or the second crank 404 rotates, it will drive the second connecting rod 502 to swing, and the second connecting rod 502 will drive the first connecting rod 501 to swing. The first connecting rod 501 and the second connecting rod 502 can respectively simulate the thigh and calf of the human leg, thereby improving the authenticity of the simulation and enhancing the interest of the whole training device.

[0049] As a preferred solution, as Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, one end of the ventilation pipe 102 far from the air hood 101 is provided with a regulating valve. The regulating valve includes a valve body 601 and a partition plate 602. The valve body 601 is connected to the side wall of the ventilation pipe 102. The valve body 601 is provided with a first ventilation hole 603 and a through-axis hole. The first ventilation hole 603 is communicated with the pipe hole of the ventilation pipe 102. A connecting shaft is connected to the partition plate 602. The partition plate 602 is rotationally connected to the through-axis hole through the connecting shaft. The partition plate 602 is provided with a second ventilation hole 604. Rotating the partition plate 602 can adjust the communication degree between the first ventilation hole 603 and the second ventilation hole 604. By providing the regulating valve, by rotating the partition plate 602, the communication degree between the second ventilation hole 604 on the partition plate 602 and the first ventilation hole 603 on the valve body 601 can be adjusted, so as to adjust the resistance when the gas passes through the regulating valve, so as to perform different degrees of force feedback on the child to adapt to the breathing training of children in different stages.

[0050] As a preferred solution, as Figure 1 and Figure 2 shown, wherein, the air hood 101 is of a funnel-shaped structure, and the funnel opening of the air hood 101 is communicated with the pipe hole of the ventilation pipe 102. Setting the air hood 101 as a funnel-shaped structure can make the inner wall of the air hood 101 fully fit with the patient's face, so as to prevent the gas exhaled by the child from leaking, so as to ensure the stable rotation of the pneumatic fan 103.

[0051] As a preferred solution, as Figure 2 shown, wherein, the air hood 101 is detachably connected to one end of the ventilation pipe 102 far from the pneumatic fan 103. By setting the air hood 101 and the ventilation pipe 102 to be detachably connected, the disassembly and installation of the air hood 101 can be facilitated, so as to facilitate the maintenance of the whole device.

[0052] As a preferred solution, as Figure 1 shown, wherein, the inner wall of the ventilation pipe 102 is provided with a wear-resistant coating. By providing a wear-resistant coating on the inner wall of the ventilation pipe 102, the wear resistance of the ventilation pipe 102 can be improved, so as to improve the service life of the whole device.

[0053] 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 principle and spirit of the present invention.
