Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a novel intelligent dynamic monitoring device for pulmonary rehabilitation and its method of use. Background Technology

[0002] In pulmonary rehabilitation, dynamic monitoring of respiratory muscle function is crucial for assessing rehabilitation effectiveness and guiding training, especially for patients after thoracic surgery and those with COPD. Existing intelligent dynamic monitoring devices for pulmonary rehabilitation mostly employ flexible straps or fixed pads to mount electrodes. Contact between the electrodes and chest skin is achieved through tightening the straps or fitting the pads to collect electromyographic signals. However, because the thoracic cavity periodically expands and contracts during respiration, fixed structures or passive elastic designs cannot dynamically adapt to this physiological change. This leads to fluctuations in electrode contact pressure. For example, thoracic expansion during inhalation may cause electrodes to loosen and signal distortion, while thoracic contraction during exhalation may cause excessive pressure on the pads. Long-term wear can easily cause skin redness, swelling, allergies, and other discomfort. Furthermore, pressure adjustment in existing devices largely relies on manual operation and cannot automatically adjust according to the patient's real-time respiratory status, making it difficult to balance signal acquisition stability and wearing comfort. This seriously affects patient compliance and the effectiveness of rehabilitation training. Summary of the Invention In view of this, the present invention proposes a novel intelligent dynamic monitor for pulmonary rehabilitation and its method of use, which can adjust the resistance according to the changes in the chest cavity during the user's breathing to achieve stable maintenance of contact pressure.

[0003] The technical solution of this invention is implemented as follows: A novel intelligent dynamic lung rehabilitation monitor includes a monitoring seat, a control panel, electromyographic electrodes, an arc-shaped pad, and a dynamic adjustment mechanism. The control panel is located on one side of the monitoring seat, and the electromyographic electrodes are located on the concave surface of the arc-shaped pad, facing the monitoring seat. The dynamic adjustment mechanism includes a displacement mechanism, a hollow tube, a spring, a moving rod, a flexible balloon, a magnetorheological fluid, an electromagnet, and a current adjustment mechanism. The displacement mechanism is located on the back of the monitoring seat and is used to drive one end of the hollow tube to move. The spring is located inside the hollow tube. One end of the moving rod extends into the hollow tube and is connected to the spring, while the other end is connected to the side wall of the arc-shaped pad. The flexible balloons are symmetrically arranged on the outer wall of the moving rod and contact the inner wall of the hollow tube. The magnetorheological fluid fills the flexible balloons. The electromagnet is located inside the moving rod and between the flexible balloons. The current adjustment mechanism is used to adjust the current delivered to the electromagnet according to the expansion and contraction of the user's lungs. The control panel is electrically connected to the electromyographic electrodes and the displacement mechanism.

[0004] Preferably, the seat also includes armrests, which are located on both sides of the monitoring seat, and the control panel is located on one side of the armrest.

[0005] Preferably, the displacement mechanism includes an electric slide and a synchronizing rod. The electric slide is disposed on the side wall of the monitoring seat, the bottom end of the synchronizing rod is connected to the moving side wall of the electric slide, the hollow tube is disposed on the top side wall of the synchronizing rod, and the control panel is electrically connected to the electric slide.

[0006] Preferably, the displacement mechanism further includes a transverse electric actuator, which is disposed on the moving side wall of the electric slide table, and its output shaft is connected to the bottom side wall of the synchronizing rod. The control panel is electrically connected to the transverse electric actuator.

[0007] Preferably, the device also includes a pressure sensor disposed on the concave surface of the arc-shaped pad, and the control panel is electrically connected to the pressure sensor.

[0008] Preferably, the current regulating mechanism includes a protective housing, a sliding rheostat, a metal plate, and a battery pack. The protective housing is disposed on the bottom surface of the hollow tube, the sliding rheostat is disposed inside the protective housing, the metal plate is disposed on the top surface of the slider of the sliding rheostat and located below the electromagnet, and the battery pack is disposed on the bottom surface of the protective housing and forms a circuit with the electromagnet and the sliding rheostat.

[0009] Preferably, the inner wall of the hollow tube is provided with a strip groove, and the flexible balloon is located in the strip groove.

[0010] Preferably, it also includes a limiting rod, the limiting rods being arranged opposite each other, and the two sides of the arc-shaped pad being connected to the side walls opposite to the limiting rods.

[0011] Preferably, the dynamic adjustment mechanism further includes a vertical electric actuator and a contact plate. The vertical electric actuator is disposed at one end of the moving rod located inside the hollow tube, and its output shaft is connected to the bottom surface of the contact plate. The top surface of the contact plate matches the shape of the inner wall of the hollow tube. The control panel is electrically connected to the vertical electric actuator.

[0012] Preferably, the method of using the monitor is as follows: When the user is sitting in the monitoring chair, a command is sent to the displacement mechanism through the control panel, which drives the arc-shaped pad to move and fit snugly against the outside of the user's chest. During spontaneous breathing, the expansion and contraction of the lungs drive the moving rod along the hollow tube via the arc-shaped pad. The current regulating mechanism adjusts the current supplied to the electromagnet according to the expansion and contraction of the lungs, and changes the hardness of the flexible balloon by changing the viscosity of the magnetorheological fluid, so as to maintain stable contact pressure or reduce skin pressure. Electromyography (EMG) electrodes collect electromyographic signals from the lung muscles during the user's breathing process and transmit them to the control panel for processing, where they are then visualized.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention discloses a novel intelligent dynamic lung rehabilitation monitor and its method of use. The user sits in a monitoring chair, and a displacement mechanism moves an arc-shaped cushion to adhere to the user's outer chest cavity, allowing electromyographic electrodes to contact the skin to collect pulmonary electromyographic signals. During the user's breathing, the lungs expand or contract, causing the chest cavity to expand or contract, thereby moving a moving rod along a hollow tube. A current adjustment mechanism adjusts the current supplied to the electromagnet according to the expansion and contraction, thus changing the strength of the magnetic field generated by the electromagnet. Under the influence of different magnetic field strengths, the magnetic flux... The magnetorheological fluid exhibits different viscosities. When the current increases, the magnetic field strength increases, the viscosity of the magnetorheological fluid increases, and it becomes almost solid. The stiffness of the flexible balloon increases, which can support the stable movement of the moving rod and maintain stable contact pressure between the electromyography electrodes and the skin, avoiding signal drift. When the current decreases, the viscosity of the magnetorheological fluid decreases, and it becomes liquid. The flexible balloon softens, and the spring can easily pull the moving rod to achieve the repositioning of the arc-shaped pad. Similarly, it keeps the electromyography electrodes in close contact with the user's chest cavity during repositioning. The electromyography signals collected by the electromyography electrodes can be transmitted to the control panel for processing and visualization to assist in lung rehabilitation.

[0016] To better understand the technical content of this invention, a specific embodiment is provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0017] See Figures 1 to 3 This invention provides a novel intelligent dynamic monitor for pulmonary rehabilitation, comprising a monitoring seat 1, a control panel 2, electromyographic electrodes 3, an arc-shaped pad 4, and a dynamic adjustment mechanism. The control panel 2 is located on one side of the monitoring seat 1, and the electromyographic electrodes 3 are located on the concave surface of the arc-shaped pad 4, facing the monitoring seat 1. The dynamic adjustment mechanism includes a displacement mechanism, a hollow tube 5, a spring 6, a moving rod 7, a flexible balloon 8, a magnetorheological fluid 9, an electromagnet 10, and a current adjustment mechanism. The displacement mechanism is located on the back of the monitoring seat 1 and is used to drive one end of the hollow tube 5 to move. The spring 6 is located in the hollow tube 5. One end of the moving rod 7 extends into the hollow tube 5 and is connected to the spring 6, while the other end is connected to the side wall of the arc-shaped pad 4. The flexible balloon 8 is symmetrically arranged on the outer wall of the moving rod 7 and contacts the inner wall of the hollow tube 5. The magnetorheological fluid 9 is filled in the flexible balloon 8. The electromagnet 10 is arranged inside the moving rod 7 and located between the flexible balloons 8. The current adjustment mechanism is used to adjust the current delivered to the electromagnet 10 according to the expansion and contraction of the user's lungs. The control panel 2 is electrically connected to the electromyographic electrode 3 and the displacement mechanism, respectively.

[0018] This invention discloses a novel intelligent dynamic lung rehabilitation monitor for real-time monitoring of lung-related data during a user's breathing process. During monitoring, the user sits in the monitoring chair 1 and initiates the monitoring process via the control panel 2. A displacement mechanism moves the moving rod 7 through the hollow tube 5, causing the arc-shaped pad 4 to descend and press against the user's outer chest cavity. Several electromyographic electrodes 3 are positioned on the concave surface of the arc-shaped pad 4. When the electromyographic electrodes 3 are in close contact with the user's chest cavity, they can collect pulmonary electromyographic signals during the user's breathing process and transmit them to the control panel 2. The control panel 2 can process these pulmonary electromyographic signals and simultaneously visualize them. The control panel 2 also displays the baseline position of normal electromyography, allowing the user to independently adjust their breathing rate or perform functional exercises such as chest wall rise and fall, causing the collected electromyographic signals to fluctuate around the baseline position, thereby promoting lung rehabilitation and assisting the user or medical personnel in assessing the lung's recovery status.

[0019] The sidewall of the arc-shaped pad 4 is connected to the moving rod 7, which can move within the hollow tube 5. A flexible spherical balloon 8 is installed on the outer wall of the moving rod 7, filled with magnetorheological fluid 9. The magnetorheological fluid 9 is liquid under normal conditions. The flexible spherical balloon 8 is relatively soft. An electromagnet 10 is installed inside the moving rod 7. When the electromagnet 10 is energized, it generates a magnetic field. Under the influence of the magnetic field, the viscosity of the magnetorheological fluid 9 changes. The stronger the magnetic field, the greater the viscosity, causing the magnetorheological fluid 9 to change towards a solid state. When the user inhales, the arc-shaped pad 4 drives the moving rod 7 to move outward along the hollow tube 5. The current regulating mechanism increases the current supplied to the electromagnet 10, which increases the magnetic field strength. As a result, the viscosity of the magnetorheological fluid 9 increases and it becomes almost solid. At this time, the flexible balloon 8 has greater stiffness, which can support the stable movement of the moving rod 7 and maintain stable contact between the electromyographic electrode 3 and the outer wall of the chest cavity, thereby achieving stable acquisition of electromyographic signals during inhalation. During exhalation, the current regulating mechanism reduces the current supplied to the electromagnet 10, and the stiffness of the flexible balloon 8 decreases. Under the action of the spring 6, the moving rod 7 and the arc-shaped pad 4 can be pulled back to their original positions, so that the electromyographic electrode 3 can move with the chest cavity contraction and maintain stable acquisition of electromyographic signals during exhalation.

[0020] Preferably, it also includes armrests 11, which are arranged on both sides of the monitoring seat 1, and the control panel 2 is arranged on the side wall of one armrest 11.

[0021] The armrest 11 is provided for users to place their arms, and the control panel 2 is located on one side of the armrest 11, which can provide real-time visualization of electromyographic signals for users to view.

[0022] Preferably, the displacement mechanism includes an electric slide 12 and a synchronizing rod 13. The electric slide 12 is disposed on the side wall of the monitoring seat 1. The bottom end of the synchronizing rod 13 is connected to the moving side wall of the electric slide 12. The hollow tube 5 is disposed on the top side wall of the synchronizing rod 13. The control panel 2 is electrically connected to the electric slide 12.

[0023] The electric slide 12 can drive the synchronous rod 13 to move up and down. The synchronous rod 13 can drive the arc-shaped pad 4 to rise and fall through the hollow tube 5 and the moving rod 7. Initially, the arc-shaped pad 4 is in a higher position. When the user sits down, the arc-shaped pad 4 can descend to the outside of the user's chest cavity and fit tightly against the user's chest cavity.

[0024] Preferably, the displacement mechanism further includes a transverse electric actuator 14, which is disposed on the moving side wall of the electric slide table 12, and its output shaft is connected to the bottom side wall of the synchronizing rod 13. The control panel 2 is electrically connected to the transverse electric actuator 14.

[0025] The horizontal electric actuator 14 can drive the synchronous rod 13 to move horizontally. When the arc-shaped pad 4 descends to the outer wall of the user's chest cavity, the horizontal electric actuator 14 can drive the synchronous rod 13 to move behind the monitoring seat 1, so that the arc-shaped pad 4 can move towards the user, thereby the arc-shaped pad 4 can contact the user's chest cavity and realize the contact between the electromyographic electrode 3 and the skin.

[0026] Preferably, it also includes a pressure sensor 15, which is disposed on the concave surface of the arc-shaped pad 4, and the control panel 2 is electrically connected to the pressure sensor 15.

[0027] The pressure sensor 15 is used to collect pressure data when the arc-shaped pad 4 comes into contact with the user's chest cavity. The pressure data is used to determine whether the arc-shaped pad 4 is in close contact with the user's chest cavity, so as to ensure the accuracy of the signal collected by the electromyography electrode 3.

[0028] Preferably, the current regulating mechanism includes a protective housing 16, a sliding rheostat 17, a metal plate 18, and a battery pack 19. The protective housing 16 is disposed on the bottom surface of the hollow tube 5, the sliding rheostat 17 is disposed inside the protective housing 16, the metal plate 18 is disposed on the top surface of the slider of the sliding rheostat 17 and located below the electromagnet 10, and the battery pack 19 is disposed on the bottom surface of the protective housing 16 and forms a circuit with the electromagnet 10 and the sliding rheostat 17.

[0029] A metal plate 18 is provided on the slider of the sliding rheostat 17. The metal plate 18 can be attracted by the electromagnet 10. When the moving rod 7 moves along the hollow tube 5, the metal plate 18 can drive the slider to move under the action of magnetic force, so that the resistance value of the sliding rheostat 17 connected in the circuit changes. At this time, the current transmitted from the battery pack 19 to the electromagnet 10 will change, thereby changing the magnetic field strength to realize the change of the viscosity of the magnetorheological fluid 9. The protective housing 16 can protect the sliding rheostat 17 and prevent the slider from moving due to external collision or accidental contact.

[0030] Preferably, the inner wall of the hollow tube 5 is provided with a strip groove 20, and the flexible balloon 8 is located in the strip groove 20.

[0031] The flexible balloon 8 is located in the strip groove 20. When its stiffness increases, it can move stably along the strip groove 20 to maintain the stability of the signal acquisition of the electromyography electrode 3.

[0032] Preferably, it also includes a limiting rod 21, the limiting rod 21 being arranged opposite to each other, and the two sides of the arc-shaped pad 4 being connected to the side walls opposite to the limiting rod 21.

[0033] The limiting rod 21 is used for installation on both sides of the arc-shaped pad 4. At the same time, the end of the moving rod 7 is connected to the side wall of the limiting rod 21, so as to drive the arc-shaped pad 4 to move synchronously through the expansion and contraction of the thoracic cavity.

[0034] Preferably, the dynamic adjustment mechanism further includes a vertical electric actuator 22 and a contact plate 23. The vertical electric actuator 22 is disposed on one end of the moving rod 7 located inside the hollow tube 5, and its output shaft is connected to the bottom surface of the contact plate 23. The top surface of the contact plate 23 matches the shape of the inner wall of the hollow tube 5. The control panel 2 is electrically connected to the vertical electric actuator 22.

[0035] In the initial stage of monitoring, the vertical electric push rod 22 will drive the abutment plate 23 to move, so that the abutment plate 23 abuts against the inner wall of the hollow tube 5, keeping the entire moving rod 7 fixed. When the user sits on the monitoring seat 1 and the arc-shaped pad 4 is driven to contact the user's chest cavity through the displacement mechanism, the arc-shaped pad 4 can be prevented from pushing the moving rod 7 to move, ensuring that the arc-shaped pad 4 is in close contact with the user's chest cavity at the beginning.

[0036] Preferably, the method of using the monitor is as follows: When the user sits in the monitoring seat 1, a command is sent to the displacement mechanism through the control panel 2, which drives the arc-shaped pad 4 to move and fit snugly against the outside of the user's chest cavity. During spontaneous breathing, the expansion and contraction of the lungs drive the moving rod 7 to move along the hollow tube 5 via the arc-shaped pad 4; The current regulating mechanism adjusts the current supplied to the electromagnet 10 according to the expansion and contraction of the lungs, and changes the hardness of the flexible balloon 8 by changing the viscosity of the magnetorheological fluid 9, so as to maintain stable contact pressure or reduce skin pressure. Electromyography electrode 3 collects electromyographic signals from the lung muscles during the user's breathing process and transmits them to control panel 2 for processing. Control panel 2 then displays the data visually.

[0037] After the user sits in the monitoring chair 1, they can actively start the monitoring process. Then, driven by the electric slide 12 and the horizontal electric push rod 14, the arc-shaped pad 4 will contact and adhere tightly to the user's chest cavity, allowing the electromyography electrodes 3 to collect electromyographic signals from the user's lungs during breathing. During the user's spontaneous breathing, the lungs will cause the chest cavity to expand and contract, which will move the moving rod 7 via the arc-shaped pad 4. During the movement of the moving rod 7, the electromagnet 10 will magnetically attract the metal plate 18, causing the slider of the sliding rheostat 17 to move, adjusting the resistance value of the sliding rheostat 17 connected in the circuit, thereby adjusting the current received by the electromagnet 10. When the current changes, the magnetic field strength of the electromagnet 10 also changes, thereby altering the viscosity of the magnetorheological fluid 9 and the stiffness of the flexible balloon 8. During inhalation, the flexible balloon 8 can support the stable movement of the moving rod 7, ensuring that the arc-shaped pad 4 deforms and the electromyographic electrode 3 can be stably attached to the user's chest cavity when pushed out, thus maintaining the stability of electromyographic signal acquisition. During exhalation, the flexible balloon can gradually soften, allowing the spring 6 to easily pull the moving rod 7 and the arc-shaped pad 4 back to their original position, ensuring that the electromyographic electrode 3 can move synchronously with the contraction of the chest cavity, thereby enabling stable acquisition of electromyographic signals during exhalation.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
