Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a COPD rehabilitation exercise device. Background Technology

[0002] For individuals with impaired lung function due to respiratory diseases (such as chronic obstructive pulmonary disease), breathing trainers are often used for rehabilitative exercises to improve respiratory capacity. Furthermore, healthy individuals can also improve their lung capacity and overall health by using breathing trainers. During normal inhalation, the diaphragm and external intercostal muscles contract. When inhaling forcefully, accessory inspiratory muscles, such as the trapezius and scalene muscles, also need to assist. The contraction of these muscles causes the chest to rise, expanding the thoracic cavity to its maximum extent. Therefore, it is necessary to train the inspiratory muscles. Breathing trainers utilize the basic principle of resistance training. Users must exert effort to resist the resistance set by the trainer when inhaling, increasing inspiratory muscle strength and thereby enhancing respiratory muscle strength and endurance.

[0003] A search revealed a novel breathing trainer with announcement number CN206444096U. The suction cup is connected to a base plate, located at the lower end of the base plate. The base plate is connected to a liquid cup, also located at the lower end of the liquid cup. A straw is connected to the liquid cup. The upper and lower halves of the breathing inlet tube are connected. A steel ball is located inside the space between the upper and lower halves of the breathing inlet tube. The lower half of the breathing inlet tube is connected to the straw. An inhalation mask is connected to the straw. The connection method is adhesive bonding. The water inlet pipe is connected to the liquid cup, the cork is connected to the water inlet pipe, the air inlet pipe is connected to the liquid cup, and the scale is connected to the base plate. The scale is located at the top of the base plate. Different water levels can create different pressures. During breathing training, after adjusting the water level to the appropriate position, inhale through the mouth into the breathing mask to create negative pressure in the liquid cup, which then allows air to enter through the air inlet pipe. The upper half of the breathing inlet pipe, the lower half of the breathing inlet pipe, and the steel ball can prevent water from overflowing from the air inlet pipe when exhaling.

[0004] The above setup has the problem that the patient's exhaled air may carry germs, and direct exhalation may enter the air and pose a safety threat to people around them. To address this issue, we provide a COPD rehabilitation exercise device. Summary of the Invention

[0005] In view of the shortcomings of existing technologies, this invention proposes a COPD rehabilitation exercise device to solve the technical problem that the patient's exhaled air may carry germs, and direct exhalation may enter the air and pose a safety threat to people around them.

[0006] The technical solution adopted in this invention is a COPD rehabilitation exercise device, comprising: The base has a liquid storage chamber containing disinfectant. An air outlet pipe is installed on the top side of the liquid storage chamber and extends downward to the lower side of the liquid storage chamber and is located in the disinfectant. A one-way air outlet valve is installed at the bottom of the air outlet pipe, and an exhaust nozzle is installed on the upper side of the liquid storage chamber. The air intake mechanism is connected to the upper end of the air outlet tube, allowing patients to exercise by blowing air into the air outlet tube through the air intake mechanism.

[0007] In a preferred embodiment, the intake mechanism includes: The top seat is fixed to the base above the middle part by a fixed shaft. The top seat has a mounting hole corresponding to the air outlet pipe. An air nozzle can be detachably installed in the mounting hole. There are multiple air supply pipes, and the diameter of the middle part of the multiple air supply pipes is different. The multiple air supply pipes are rotatably installed between the base and the top seat around a fixed axis. Any one of the air supply pipes can connect the air nozzle and the air outlet pipe.

[0008] In a preferred embodiment, a sleeve is rotatably mounted between the base and the top seat about a fixed axis, and the plurality of gas supply pipes are fixed to the inner side of the sleeve.

[0009] In a preferred embodiment, an air inlet pipe is installed on the lower side of each of the plurality of air supply pipes, and a one-way air inlet valve is provided in each of the air inlet pipes.

[0010] In a preferred embodiment, the top seat is provided with a disinfection mechanism for disinfecting the gas delivery pipe. The disinfection mechanism includes a follow-motion component and a liquid supply component. The follow-motion component is used to follow the rotation of the gas delivery pipe, and the liquid supply component adds disinfectant to the gas delivery pipe.

[0011] In a preferred embodiment, the following motion component includes a sliding nozzle, a first arc-shaped groove is provided at the bottom of the top seat, the sliding nozzle slides in the first arc-shaped groove and is on the movement trajectory of the air supply pipe, the sliding nozzle is equipped with a first magnetic block, a second magnetic block matching the first magnetic block is installed at the upper end of a plurality of air supply pipes, and a first elastic element is provided between the sliding nozzle and the arc-shaped groove.

[0012] In a preferred embodiment, the liquid supply assembly includes a piston cylinder, the top seat has an installation groove, the piston cylinder is installed in the installation groove, a piston is slidably sealed inside the piston cylinder, the piston is fixed with a connecting rod extending out of the piston cylinder, a push-pull rod is hinged to the end of the connecting rod, and the end of the push-pull rod is hinged to the sliding nozzle; The top seat has an internal cavity containing disinfectant. The piston cylinder is connected to the cavity via a one-way inlet pipe, and the piston cylinder is connected to the sliding nozzle via a one-way outlet hose.

[0013] In a preferred embodiment, the top of the base is provided with a drainage component for draining the disinfectant solution inside the infusion tube.

[0014] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: 1. The patient's exhaled air will enter the disinfectant solution, which will sterilize and disinfect the patient's exhaled air, thereby reducing the spread of germs.

[0015] 2. This device rotates the sleeve to drive the air delivery tubes of different central diameters, which can easily switch the air delivery tubes of different inner diameters, thereby adjusting the blowing resistance. It can simultaneously meet the needs of COPD patients for blowing resistance training and inspiratory resistance training, and can perform inspiratory training without the need for additional equipment replacement.

[0016] 3. The following motion component and liquid supply component of the disinfection mechanism of this device work together to automatically disinfect and sterilize the inner wall of the air tube each time the patient switches the air tube. This prevents bacteria from growing in the tube after long-term use and effectively reduces the spread of germs. Only the air nozzle needs to be replaced for different trainees to use. This avoids cross-infection of respiratory diseases caused by different trainees using the same breathing trainer. Attached Figure Description

[0020] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0022] Example: like Figure 1-8 As shown, this embodiment provides a COPD rehabilitation exercise device, including: The base 1 has a liquid storage chamber 11, which stores disinfectant. A vent pipe 12 is installed on the top side of the liquid storage chamber 11. The vent pipe 12 extends downward to the lower side of the liquid storage chamber 11 and is located in the disinfectant. A one-way vent valve 121 is installed at the bottom of the vent pipe 12. An exhaust nozzle 13 is installed on the upper side of the liquid storage chamber 11. The air intake mechanism is connected to the upper end of the air outlet pipe 12. Patients can exercise by blowing air into the air outlet pipe 12 through the air intake mechanism.

[0023] During rehabilitation exercises, COPD patients blow air into the exhaust tube 12 using the air intake mechanism. The exhaled air enters the disinfectant solution. After the disinfectant solution comes into contact with the patient's exhaled air, its active ingredients can kill or inhibit germs, thereby reducing the risk of germ transmission. Finally, the air is discharged to the outside through the exhaust nozzle 13. By setting up a disinfection mechanism, the spread of germs can be effectively reduced.

[0024] The one-way exhaust valve 121 can prevent disinfectant from flowing into the air intake mechanism and at the same time prevent irritating components in the disinfectant from entering the patient's body, so as to avoid irritating the respiratory mucosa and causing symptoms such as coughing and difficulty breathing.

[0025] The vent 13 is located on the upper side of the liquid storage chamber 11, above the liquid level of the disinfectant, and is equipped with a one-way gas valve to prevent the disinfectant from being discharged into the outside.

[0026] In this embodiment, the disinfectant is preferably a chlorine-containing disinfectant. When germs in exhaled breath come into contact with the disinfectant, the active ingredients in the disinfectant may kill or inhibit the germs, thereby reducing the spread of germs.

[0027] The intake mechanism includes: The top seat 2 is fixed above the base 1 by a fixed shaft in the middle. The top seat 2 has a mounting hole 21 corresponding to the air outlet pipe 12. An air nozzle 22 can be detachably installed in the mounting hole 21. There are multiple air supply pipes 23, and the diameter of the middle part of the multiple air supply pipes 23 is different. The multiple air supply pipes 23 are rotatably installed between the base 1 and the top seat 2 around a fixed axis. Any one of the air supply pipes 23 can connect the air nozzle 22 and the air outlet pipe 12.

[0028] A sleeve 24 is rotatably mounted between the base 1 and the top seat 2 around a fixed axis, and multiple gas supply pipes 23 are fixed to the inside of the sleeve 24.

[0029] When different COPD patients require different blowing resistance for rehabilitation training, simply rotate the sleeve 24 between the base and the top seat. This will cause multiple air delivery tubes 23 with different central diameters arranged around a fixed axis inside the sleeve 24 to rotate, allowing the target air delivery tube 23 to be used to be rotated to the corresponding position, with its upper end aligned with the air nozzle 22 on the top seat 2 and its lower end aligned with the air outlet tube 12 on the base 1. This allows for switching between air delivery tubes with different inner diameters to adjust the blowing resistance, adapting to the exercise needs of patients with different conditions and at different stages of rehabilitation. The switching process is simple and quick, without requiring patients to manually disassemble and replace the tubing. It is easy to operate and has a higher adaptability.

[0030] In other embodiments, a positioning component can be provided between the sleeve 24 and the top seat 2 or the base 1. The positioning component is an elastic positioning rod provided at the upper or lower end of the sleeve 24. The elastic positioning rod corresponds to multiple air supply pipes 23. The base 1 or the top seat 2 can be provided with a positioning groove corresponding to the air outlet pipe 12. When the sleeve 24 rotates, the elastic positioning rod extends into the positioning groove, and the air supply pipe 23 and the air outlet pipe 12 are completely aligned. By rotating the sleeve 24 with a little force, the elastic positioning rod can be retracted and leave the positioning groove.

[0031] Each of the multiple gas supply pipes 23 has an air inlet pipe 231 installed on its lower side, and each air inlet pipe 231 is equipped with a one-way air inlet valve 232.

[0032] By setting up the air inlet tube 231, inhalation training can be performed. When the patient inhales, outside air enters the air delivery tube 23 through the air inlet tube 23, and the patient then inhales through the air nozzle 22. The one-way air inlet valve 232 can prevent the patient's exhaled air from being discharged from the air inlet tube 231. In this way, the needs of COPD patients for both exhalation resistance training and inhalation resistance training can be met at the same time, and the requirements of respiratory muscle rehabilitation training can be more comprehensively adapted.

[0033] For some patients with symptoms of inspiratory muscle weakness, inspiratory training can be performed directly without replacing the equipment, further enhancing the practicality of the device.

[0034] The top seat 2 is equipped with a disinfection mechanism for disinfecting the gas supply pipe 23. The disinfection mechanism includes a follow-motion component and a liquid supply component. The follow-motion component is used to follow the rotation of the gas supply pipe 23, and the liquid supply component adds disinfectant to the gas supply pipe 23.

[0035] The following motion component includes a sliding nozzle 3. The bottom of the top seat 2 is provided with a first arc-shaped groove 31. The sliding nozzle 3 slides in the first arc-shaped groove 31 and is on the movement trajectory of the air supply pipe 23. The length of the first arc-shaped groove 31 is less than the distance between two adjacent air supply pipes 23. The sliding nozzle 3 is equipped with a first magnetic block 32. The upper ends of multiple air supply pipes 23 are each equipped with a second magnetic block 33 that matches the first magnetic block 32. A first elastic element 34 is provided between the sliding nozzle 3 and the arc-shaped groove 31.

[0036] The liquid supply assembly includes a piston cylinder 4, a mounting groove 41 is provided on the top seat 2, the piston cylinder 4 is installed in the mounting groove 41, a piston 42 is provided in the piston cylinder 4 and is sealed and slidably provided inside the piston cylinder 4, a connecting rod 43 extending out of the piston cylinder 4 is fixed to the piston 42, a push-pull rod 44 is hinged to the end of the connecting rod 43, and the end of the push-pull rod 44 is hinged to the sliding nozzle 3. The top seat 2 has a cavity 45 inside, which stores disinfectant. The piston cylinder 4 is connected to the cavity 45 through a one-way inlet pipe 46, and the piston cylinder 4 is connected to the sliding nozzle 3 through a one-way outlet hose 47.

[0037] When the patient switches the inhalation tube 23, when the used target inhalation tube 23 rotates to the sliding nozzle 3 position, the inhalation tube 23 and the sliding nozzle 3 are completely aligned. The first magnetic block 32 and the second magnetic block 33 attract each other, causing the sliding nozzle 3 to slide synchronously along the first arc groove 31 following the inhalation tube 33. During the sliding process, the first elastic element 34 is compressed, and the sliding nozzle 3 pushes the push-pull rod 44. The push-pull rod 44 pushes the connecting rod 43 and the piston 42 to slide away from the sliding nozzle 3 inside the piston cylinder 4. The disinfectant inside the piston cylinder 42 is squeezed into the sliding nozzle 3 through the one-way outlet hose 47, and then flows into the tube along the inner wall of the inhalation tube 23, disinfecting and sterilizing the inner wall of the recently used inhalation tube 23. Because the length of the first arc groove 31 is less than that of two adjacent... The distance between the gas delivery pipes 23 is such that before the next gas delivery pipe 23 moves to the position of the air inlet pipe 12, the sliding nozzle 3 compresses the first elastic element 34 to its limit and can no longer follow the target gas delivery pipe 23. That is, it overcomes the magnetic force between the first magnetic block 32 and the second magnetic block 33, and the target gas delivery pipe 23 will separate from the sliding nozzle 3. Finally, the next gas delivery pipe 23 moves to the position of the air inlet pipe 12. After the sliding nozzle 3 separates, it is reset under the elastic force of the first elastic element 34. Then, the push-pull rod 44 pulls the connecting rod 43 and the piston 42 to slide in the piston cylinder 4 towards the sliding nozzle 3. At this time, a negative pressure is formed in the piston cylinder 4, and the disinfectant stored in the cavity 45 is sucked into the piston cylinder through the one-way liquid inlet pipe 46, waiting for the next use. Each time the gas supply tube 23 is switched, the tube that has just been used can be automatically disinfected, which prevents bacteria from growing on the inner wall of the tube due to residual exhaled air and moisture after long-term use, improves the hygiene of the device and reduces the risk of cross-infection.

[0038] Furthermore, since the air nozzle 22 can be detachably installed in the mounting hole 21, it can be used by different trainees simply by replacing the air nozzle 22, and can avoid cross-infection of respiratory diseases caused by different trainees using the same breathing trainer.

[0039] The top of the base 1 is equipped with a drainage component for draining the disinfectant solution inside the infusion tube 23; The drainage assembly can drain the disinfectant inside the infusion tube 23 into the storage chamber 11 of the base 1. The specific structure is as follows: The drain assembly includes a drain sleeve 5, a second arc-shaped groove 51 is provided on the top of the top seat 1, the drain sleeve 5 slides in the second arc-shaped groove 51, a second magnetic block 33 is also installed at the bottom of the gas pipe 23, a third magnetic block 52 matching the second magnetic block 33 is installed on the top of the drain sleeve 5, a second elastic element 53 is provided between the drain sleeve 5 and the second arc-shaped groove 51, and a baffle 54 for blocking the second arc-shaped groove 51 is installed at the bottom of the drain sleeve 5. The drain sleeve 5 is equipped with a sealing assembly, which includes a sealing block 55. The drain sleeve 5 has a groove 56 in the middle. A third elastic element 57 is provided between the sealing block 55 and the groove 56 on one side. A top rod 58 is installed on the other side of the sealing block 55. The side wall of the second arc groove 51 has a movable groove 59 that matches the top rod 58.

[0040] In this embodiment, reference Figure 6-8 As shown, in the initial state, the top rod 58 abuts against the side wall of the second arc groove 51. At this time, the sealing block 55 blocks the drainage channel of the drainage sleeve 5, that is, the disinfectant inside the storage chamber 11 cannot enter the sleeve 24 through the drainage sleeve 5. When the patient switches the infusion tube 23 again, the target infusion tube 23 carrying disinfectant moves to the position of the drain sleeve 5. The infusion tube 23 and the drain sleeve 5 are completely aligned. The second magnetic block 33 and the third magnetic block 52 at the bottom of the infusion tube 23 attract each other, causing the drain sleeve 5 to follow the movement. During the following movement, the push rod 58 will move to the movable groove 59. The elastic force of the third elastic element 57 pushes the sealing block 55 to slide in the sliding groove 56, so that the drain channel in the middle of the drain sleeve 5 opens. Thus, the disinfectant in the infusion tube 23 will flow from the drain channel in the middle of the drain sleeve 5 into the storage chamber 11. The infusion tube 23 continues to move, and after the drain sleeve 5 compresses the second elastic element 53 to its limit, it can no longer follow the movement. The second magnetic block 33 and the third magnetic block 52 will separate. The elastic force of the second elastic element 53 pushes the drain sleeve 5 back to the initial state, thus blocking the drain channel in the middle of the drain sleeve 5. After the drain sleeve 5 is reset, the baffle 54 can block the second arc groove 51, which can prevent the disinfectant from flowing out of the storage chamber 11 when the device is shaken. With this design, the drain channel in the middle of the drain sleeve 5 will be opened when the gas supply pipe 23 is switched, so that the disinfectant in the gas supply pipe 23 can be discharged.

[0041] In other implementations, the structure of the drain sleeve 5 may not include a sealing component, but instead includes a supply component. That is, when the drain sleeve 5 moves with the infusion tube 23, it draws the disinfectant in the infusion tube 23 into the piston cylinder. When the drain sleeve 5 resets, it drains the disinfectant in the piston cylinder into the storage chamber 11.

[0042] After switching the inhalation tube 23, disinfectant may remain inside the inhalation tube 23. Therefore, after each switch of the inhalation tube 23, the patient should first perform exhalation training to avoid inhaling the disinfectant into the mouth.

[0043] In this embodiment, sealing gaskets are provided at both the upper and lower ends of the gas delivery pipe 23. The sealing gaskets can increase the sealing between the gas delivery pipe 23 and the top seat 2 and the base 1. During the rotation of the gas delivery pipe 23, the sealing gaskets can always be in contact with the base 1, so that the disinfectant in the gas delivery pipe 23 will not overflow onto the surface of the base 1. After the gas delivery pipe 23 is aligned with the gas outlet pipe 12, the sealing gaskets can also prevent the exhaled gas from leaking out.

[0044] In this embodiment, the first elastic element 34, the second elastic element 53, and the third elastic element 57 are all springs.

[0045] In other embodiments, the top seat 2 is provided with a liquid inlet communicating with the cavity 45. The liquid inlet is provided with a sealing plug, which can block the liquid inlet and facilitate the addition of disinfectant into the cavity 45 through the liquid inlet. Similarly, the base 1 is also equipped with a drain port for replacing the disinfectant inside the storage chamber 11.

[0046] The working principle of the embodiments is explained in detail below: The patient installs the detachable air nozzle 22 into the mounting hole 21 of the top seat 2. According to their own condition and recovery stage, the upper end of the target air delivery tube 23 with the appropriate inner diameter is aligned with the air nozzle 22 of the top seat 2, and the lower end is aligned with the air outlet tube 12 on the base 1. The patient blows air into the air delivery tube 23 through the air nozzle 22. The gas enters the disinfectant in the liquid storage chamber 11 of the base 1 through the air outlet tube 12. After the disinfectant kills or inhibits the germs in the gas, the gas is discharged to the outside through the exhaust nozzle 13.

[0047] When the patient inhales, outside air enters the air supply tube 23 through the inlet tube 231 on the lower side of the air supply tube 23, and is then inhaled into the patient's body through the air nozzle 22. The one-way inlet valve 232 prevents the patient's exhaled air from being discharged from the inlet tube 231.

[0048] When it is necessary to switch the gas supply pipe 23 to adjust the blowing resistance, rotate the sleeve 24 to rotate the next target gas supply pipe 23 to the corresponding position.

[0049] During the switching process, when the used gas delivery pipe 23 rotates to the position of the sliding nozzle 3, the gas delivery pipe 23 and the sliding nozzle 3 are completely aligned. The first magnetic block 32 and the second magnetic block 33 attract each other, causing the sliding nozzle 3 to slide synchronously along the first arc groove 31 with the gas delivery pipe 33. During the sliding process, the push-pull rod 44 is pushed, which in turn pushes the connecting rod 43 and the piston 42 to slide inside the piston cylinder 4. The disinfectant inside the piston cylinder 42 is squeezed into the sliding nozzle 3 through the one-way liquid outlet hose 47, and then flows into the pipe along the inner wall of the gas delivery pipe 23 to disinfect and sterilize the inner wall of the gas delivery pipe 23 that has just been used, waiting for the next use.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
