Description

Technical Field

[0001] This invention relates to the field of respiratory training equipment technology, and in particular to a portable respiratory function trainer. Background Technology

[0002] For patients with respiratory or lung function problems, such as those with COPD, respiratory function training is usually required to promote respiratory function recovery. Currently, the most common method is to use a device for inhalation training. During training, first take a slow, deep breath through your nose, hold your breath for two to three seconds after inhaling to the maximum extent, and then slowly and persistently blow air through your mouth into the device, preferably for more than ten seconds, the longer the better. Then breathe normally through your nose and rest for a while, and then repeat the above actions. Do this for two to three sets a day, with eight to ten repetitions per set. If dizziness or lightheadedness occurs during the inhalation process, this is a sign of hyperventilation. You can rest for a while and then shorten the inhalation time in the next inhalation.

[0003] Some current training devices can adjust the training intensity to meet the training needs of different stages, but others can only perform blowing training at a single intensity. Moreover, existing devices lack auxiliary functions such as timing and counting. As a result, patients have to judge the length of blowing time by their own senses. This leads to neither the patient nor the medical staff knowing the patient's blowing time or the patient's specific recovery status. Furthermore, it is not easy for patients to record how many times they have done while blowing, thus affecting the assessment of the patient's condition and hindering the patient's recovery. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the prior art, the purpose of this invention is to provide a portable breathing function trainer, which effectively solves the problem that existing breathing training devices have limited functions and cannot meet training needs.

[0005] The technical solution is as follows: The present invention includes a main box, inside which are two vertically distributed and horizontally movable rods. The two movable rods move in opposite directions and are L-shaped with different directions. A transparent block is fixed to the left end of the main box. A liquid storage tank is opened inside the transparent block. An air inlet slot is opened at the upper end of the transparent block and is vertically connected to the liquid storage tank. A sealing plate that can block the air inlet slot is fixed to the left end of the upper movable rod. The sealing plate is slidably connected to the transparent block. A connecting slot in an S-shape is opened on the right side of the transparent block and is connected to the lower end of the liquid storage tank. A sealing block that moves up and down with the upper movable rod and can block the connecting slot is provided on the transparent block. A transparent liquid hourglass is fixed to the upper end of the main box. A conical block that can move up and down with the upper movable rod and can block the connection between the upper and lower sides of the liquid hourglass is provided inside the liquid hourglass. The main body box has a fixed air inlet pipe that communicates with the connecting groove and runs in a left-right direction. The air inlet pipe is square and passes through the main body box at both ends. The front and rear ends of the air inlet pipe are respectively provided with air leakage grooves that run through the front and rear. An L-shaped diverter plate is slidably connected in the air leakage groove. The inner sides of the two diverter plates are inclined and form a figure-eight shape with the left side larger than the right side. The two diverter plates can move relative to each other or away from each other. A pneumatic box is fixed on the outside of the air inlet pipe. The air leakage groove is located in the pneumatic box. A lightweight plate with an inverted L shape located to the left of the diverter plate is slidably connected in the pneumatic box. The lightweight plate moves to the left as the patient blows air and moves to the right with the moving rod on the lower side. A rotating column with an up-down axial direction is rotatably connected to the upper end of the main body box. The upper end of the rotating column passes through the main body box and is fixed with a pointer. Multiple readings are fixed on the upper end of the main body box and are evenly distributed along the circumference of the rotating column. When the lightweight plate moves to the right with the moving rod on the lower side, the pointer rotates to the next reading.

[0006] The beneficial effects of this invention are as follows: the linkage mechanism enables the synchronous and automatic completion of blowing training, timing, and counting, effectively solving the problem that patients need to judge the blowing time and number of times by feeling; its adjustable flow structure can flexibly adjust the blowing resistance to adapt to the intensity requirements of different rehabilitation stages; the overall design integrates bubble observation, liquid hourglass timing, and pointer counting functions into a compact and portable main body box, which is simple and intuitive to operate, significantly improving the scientific nature, recordability, and patient compliance of the training, and facilitating medical staff to accurately assess rehabilitation progress and meet the diverse training needs of patients.

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 11 The device includes a main body box 1, which contains two vertically distributed and horizontally movable rods 2. The two rods 2 move in opposite directions and are L-shaped. A transparent block 3 is fixed to the left end of the main body box 1. A liquid storage tank 4 is opened inside the transparent block 3. An air inlet slot is opened at the upper end of the transparent block 3 and is connected to the liquid storage tank 4. A sealing plate 5 is fixed to the left end of the upper movable rod 2 to block the air inlet slot. The sealing plate 5 is slidably connected to the transparent block 3. A connecting slot 6 with the lower end of the liquid storage tank 4 and is S-shaped is opened on the right side of the transparent block 3. A sealing block 7 is provided on the transparent block 3, which moves up and down with the upper movable rod 2 and can block the connecting slot 6. A transparent liquid hourglass 8 is fixed to the upper end of the main body box 1. A conical block 9 is provided inside the liquid hourglass 8, which moves up and down with the upper movable rod 2 and can block the connection between the upper and lower sides of the liquid hourglass 8. The main body box 1 is fixed with an air inlet pipe 10 that communicates with the connecting groove 6 and runs in a left-right direction. The air inlet pipe 10 is square and penetrates the main body box 1 at both ends. The front and rear ends of the air inlet pipe 10 are respectively provided with air leakage grooves that run through the front and rear. The air leakage grooves are slidably connected with L-shaped diverter plates 11. The inner sides of the two diverter plates 11 are inclined and form a figure-eight shape with the left side larger than the right side. The two diverter plates 11 can move relative to each other or away from each other. A pneumatic box 12 is fixed to the outside of the air inlet pipe 10, and the air leakage grooves are located in the pneumatic box 12. Inside the pneumatic box 12, there is a lightweight plate 13 in the shape of an inverted L located to the left of the diverter plate 11. The lightweight plate 13 moves to the left as the patient blows air and moves to the right with the lower moving rod 2. The upper end of the main body box 1 is rotatably connected to a rotating column with an upper and lower axis. The upper end of the rotating column passes through the main body box 1 and is fixed with a pointer 14. The upper end of the main body box 1 is fixed with multiple readings 15 evenly distributed along the circumference of the rotating column. When the lightweight plate 13 moves to the right with the lower moving rod 2, the pointer 14 rotates to the next reading 15.

[0020] To enable the two movable rods 2 to move left and right in opposite directions, the movable rods 2 are slidably connected to the main body box 1. A control block 16 is slidably connected to the right end of the main body box 1. The lower end of the control block 16 is fixedly connected to the main body box 1 via a strong compression spring. Two guide grooves 17 are provided on the control block 16, which are distributed vertically and form a V-shape with the left side smaller than the right side. The rear end of the movable rod 2 is fixed with a guide post 18 that is inserted into the guide groove 17 on its corresponding side and can move within the guide groove 17. The guide post 18 contacts the side wall of the guide groove 17. The upper guide post 18 is located at the left end of the upper guide groove 17, and the lower guide post 18 is located at the right end of the lower guide groove 17. A control rod 19 with its upper end penetrating the main body box 1 is fixed to the upper end of the control block 16. The control rod 19 is slidably connected to the main body box 1.

[0021] In order to make the sealing block 7 move up and down with the upper moving rod 2, the sealing block 7 is slidably connected to the transparent block 3. The upper end of the sealing block 7 is fixed with an inclined frame 20 that is higher on the left and lower on the right. The front end of the upper moving rod 2 is fixed with a linkage column 21 that is inserted into the inclined frame 20 and contacts the inner wall of the inclined frame 20.

[0022] To enable the conical block 9 to move up and down with the upper moving rod 2, an inverted L-shaped protective box is fixed to the upper end of the main body box 1. The protective box is fixedly connected to the upper end of the liquid hourglass 8. A pull rod 22 of the same shape is slidably connected inside the protective box. The lower end of the pull rod 22 is inserted into the main body box 1 and a pull frame 23 with the left side higher than the right side is fixed therein. A pull post 24 is fixed to the front end of the upper moving rod 2, which is inserted into the pull frame 23 and contacts the inner wall of the pull frame 23. A connecting post 25 is coaxially fixed to the upper end of the conical block 9. The upper end of the connecting post 25 passes through the liquid hourglass 8 and the protective box and is fixedly connected to the pull rod 22.

[0023] To facilitate the repositioning of the liquid inside the liquid hourglass 8 and to facilitate time determination, an arc-shaped connecting frame 26 is fixed to the left end of the liquid hourglass 8. The upper and lower ends of the liquid hourglass 8 are respectively connected to the connecting frame 26. The connecting frame 26 is fixedly connected to the protective box. A scale line 27 is fixed to the upper side of the liquid hourglass 8.

[0024] In order to enable the two diverter plates 11 to move relative to each other or away from each other, a sliding plate 28 is slidably connected inside the main body box 1. The sliding plate 28 has inclined grooves 29 on its front and rear sides respectively. The two inclined grooves 29 form a figure-eight shape with the left side being larger than the right side. The outer end of the diverter plate 11 passes through the pneumatic box 12 and is fixed with a sliding column 30 in the upper and lower axial directions. The upper end of the sliding column 30 is inserted into the inclined groove 29 on its corresponding side and can move within the inclined groove 29. The sliding column 30 contacts the side wall of the inclined groove 29.

[0025] To facilitate control of the distance between the two diverter plates 11, the front end of the main body box 1 is provided with a left-right adjustment groove. An adjustment block 31 is slidably connected in the adjustment groove. The front end of the adjustment block 31 extends out of the adjustment groove and its rear end is fixedly connected to the sliding plate 28. The front end of the main body box 1 is provided with multiple limiting grooves 32 that are evenly distributed in the left-right direction and communicate with the adjustment groove. A limiting block 33 that can be inserted into the limiting groove 32 is slidably connected on the adjustment block 31. The lower end of the limiting block 33 is fixedly connected to the adjustment block 31 via a compression spring.

[0026] In order for the pointer 14 to rotate to the next reading 15 when the lightweight plate 13 moves to the right with the lower moving rod 2, a ratchet 34 located in the main body box 1 is fixed at the lower end of the rotating column. A fixed pawl 35 that cooperates with the ratchet 34 is hinged in the main body box 1. The fixed pawl 35 is fixedly connected to the main body box 1 via an elastic sheet. The left end of the lightweight plate 13 passes through the pneumatic box 12 and is fixed with an auxiliary plate 36. The left end of the auxiliary plate 36 can contact the right end of the lower moving rod 2. The right end of the auxiliary plate 36 is hinged with a movable pawl 37 that can cooperate with the ratchet 34. The left end of the movable pawl 37 can contact the right end of the auxiliary plate 36. The left end of the movable pawl 37 is fixedly connected to the auxiliary plate 36 via a weak elastic rope 38. A flat pressure groove 39 that runs through the left and right sides is opened at the left end of the pneumatic box 12.

[0027] For ease of use, a water level line 40 is fixed to the left end of the transparent block 3, and the water level line 40 is located below the air inlet pipe 10. A blower head 41 with a smaller left side and a larger right side is detached and connected to the right end of the air inlet pipe 10.

[0028] In use, the initial state of this invention is as follows: the linkage column 21 is located at the extreme position on the upper side of the inclined frame 20, the pull column 24 is located at the extreme position on the upper side of the pull frame 23, the conical block 9 is inserted into the connection between the upper and lower parts of the liquid hourglass 8 and blocks the connection, so that the liquid on the upper side of the liquid hourglass 8 cannot flow to the lower side of the liquid hourglass 8 through the connection, there is no liquid on the lower side of the liquid hourglass 8, the liquid is located in the upper part of the liquid hourglass 8 and the liquid level is much lower than the upper opening of the connecting frame 26, the liquid storage tank 4 is filled with liquid, the upper end of the liquid is not higher than the water level line 40, the sealing plate 5 blocks the air inlet slot, and the sealing block 7 blocks the connecting slot 6. At this time, the liquid in the storage tank 4 is in a sealed state, thereby preventing liquid leakage. The angle at which the moving pawl 37 pushes the ratchet 34 to rotate once is equal to the central angle between two adjacent readings 15. The moving pawl 37 pushes the ratchet 34 to rotate counterclockwise, and the reading 15 is set to gradually increase in the counterclockwise direction. The pointer 14 is in the left and right direction with the arrow pointing to the left. At this time, the reading 15 pointed to by the pointer 14 is one. The moving pawl 37 is located to the right of the ratchet 34 and does not contact the ratchet 34. The limit block 33 is inserted into the rightmost limit groove 32, and the sliding column 30 is located at the left limit position of the inclined groove 29. When training is needed, take out a new blow nozzle 41, insert the blow nozzle 41 into the opening at the right end of the air inlet tube 10, hold the main body box 1, place your fingers on the control lever 19 but do not press down, take a deep breath through your nose and hold your breath for two or three seconds, when exhaling, put your mouth on the blow nozzle 41 so that the blow nozzle 41 covers your mouth, then press the control lever 19 down to the limit position and blow air. As the control lever 19 moves downward, the control block 16 and its guide groove 17 move downward synchronously. Driven by the guide groove 17, the upper moving lever 2 moves to the right. The upper moving lever 2 drives the sealing plate 5, pull column 24, and linkage column 21 to move to the right. The movement of the sealing plate 5 exposes the air inlet groove, facilitating the discharge of gas blown into the reservoir 4 by the patient. The pull column 24 drives the pull frame 23 to move upward. The pull frame 23, via the pull rod 22, drives the connecting column 25 and the conical block 9 to move upward. The conical block 9 no longer obstructs the connection between the upper and lower sides of the liquid hourglass 8, and the liquid on the upper side of the liquid hourglass 8 drips into the narrower connection in the middle. The timekeeping is achieved by placing the hourglass 8 on the lower side. At the same time, the linkage column 21 drives the inclined frame to move upward, and the inclined frame drives the sealing block 7 to move upward, thereby connecting the air inlet pipe 10 with the connecting groove 6 and the liquid storage tank 4, so that the air blown by the patient can enter the liquid storage tank 4. Since the water level line 40 is located below the air inlet pipe 10, the liquid level will not change when the connecting groove 6 is connected to the air inlet pipe 10, and the liquid will not enter the air inlet pipe 10, thus ensuring the normal blowing. At the same time, the guide groove 17 on the lower side will push the guide column 18 on the lower side to move to the left, thereby moving the moving rod 2 on the lower side to the left, and the moving rod 2 on the lower side away from the auxiliary plate 36. After the patient exhales air into the inlet pipe 10, the air is diverted by the two diverter plates 11, and the air from both sides enters the pneumatic box 12. Since the pneumatic box 12 is in a sealed state, as air continues to enter, it pushes the lightweight plate 13 to the left. The air on the left side of the lightweight plate 13 in the pneumatic box 12 is discharged from the pneumatic box 12 through the flat pressure groove 39. The lightweight plate 13 drives the auxiliary plate 36 and the moving pawl 37 to move to the left. After the moving pawl 37 moves a certain distance to the left, it contacts the ratchet 34 and the ratchet... Under the action of 34, it swings to the right. Since the elasticity of the weak elastic rope 38 is very weak, it will not hinder the swing of the moving pawl 37, thus ensuring that the gas blown out by the patient can smoothly move the moving pawl 37 to the left of the ratchet 34. At the same time, the gas blown out by the patient enters the connecting groove 6 through the air inlet pipe 10 from the space between the two diverter plates 11 and enters the liquid storage tank 4 to generate bubbles in the liquid. This allows the patient to judge whether the blowing condition meets the requirements. The normal requirement is that bubbles are continuously generated. After the air blowing is complete, release the control lever 19. The control block 16 moves upward under the action of the strong compression spring. The control block 16 drives the upper moving rod 2 to move to the left and the lower moving rod 2 to move to the right via the guide groove 17 and guide column 18. The upper moving rod 2 drives the sealing plate 5 to move to the left again to block the air inlet groove. The linkage column 21 drives the sealing block 7 to move downward via the inclined frame 20 to block the connecting groove 6. The pull column 24 drives the pull rod 22 to move downward via the pull frame 23. The conical block 9 blocks the connection between the upper and lower sides of the liquid hourglass 8 again. The liquid hourglass 8 stops timing. At this time, the liquid can be observed. The scale line 27 on the upper side of the hourglass 8 determines the duration of blowing. At the same time, the moving rod 2 on the lower side moves a certain distance to the right and then contacts the auxiliary plate 36, pushing the auxiliary plate 36 to move to the right. The moving pawl 37 gradually contacts the ratchet 34 and swings to the left. After the moving pawl 37 swings to the left a certain distance, it contacts the auxiliary plate 36, thereby causing the moving pawl 37 to push the ratchet 34 to rotate. After the moving pawl 37 rotates a certain angle, it disengages from the ratchet 34, and the ratchet 34 stops rotating. At this time, the reading 15 pointed to by the pointer 14 is two, which proves that one training session has been completed and one count is performed. Hold the main body box 1 and rotate it so that all the liquid on the lower side of the liquid hourglass 8 flows into the connecting frame 26. Then, rotate the main body box 1 to allow the liquid in the connecting frame 26 to enter the upper side of the liquid hourglass 8. This resets the liquid hourglass 8, making it convenient for the next counting. The above operation can be repeated for further training. After a period of training, the patient's function improves. At this point, the training intensity needs to be increased. Pressing down on the limiting block 33 causes it to move downward and compress the spring. The limiting block 33 moves out of the limiting groove 32, releasing the limitation on the sliding plate 28. Pushing the adjusting block 31 to the left causes the sliding plate 28 to move to the left. When it moves to the next limiting groove 32, the limiting block 33 is released, and it moves upward and inserts into the limiting groove 32, thus limiting the position of the sliding plate 28 again. This achieves multi-level adjustment. During the movement of the sliding plate 28 to the left, the two inclined grooves 29 on the sliding plate 28 cause the two diverter plates 11 to move relative to each other. The distance between the right ends of the two diverter plates 11 decreases, allowing more gas to enter the pneumatic box 12. If the patient wants the gas to enter the reservoir 4 to generate bubbles, they need to blow more forcefully and maintain stability for a longer period of time while blowing. This achieves breathing training under different resistance levels, meeting the needs of different stages and different patients. After training, reset the liquid hourglass 8 according to the above operation, and then rotate the pointer 14 counterclockwise with your finger so that the pointer 14 is aligned with the initial reading 15 again. The blower head 41 can be removed or reused as needed. In this way, the blower head 41 only needs to be wiped and disinfected before the next use. When carrying the device out or putting it in a bag, although the control lever 19 will not shift due to accidental touches under the action of the strong compression spring, to prevent excessive pressure, the control lever 19 can be pressed down to expose the air inlet slot, and then the liquid in the reservoir 4 can be poured out. When training is required, the control lever 19 can be pressed down again to expose the air inlet slot, and then water can be poured into the reservoir 4. Note that the liquid level should be below the water level line 40. Since no blowing operation is performed during the pressing of the control lever 19, the lightweight plate 13 will not move. Thus, the pointer 14 will not rotate after the control lever 19 is released, thereby ensuring that each rotation of the pointer 14 occurs after the patient has performed a blowing exercise, ensuring the accuracy of the count.

[0029] The sealing plate 5 and sealing block 7 of the present invention have sealing rings and other sealing structures at the connection between the sealing plate 5 and sealing block 7 and the transparent block 3, as well as at the connection between the connecting column 25 and the liquid hourglass 8, so as to prevent the leakage of liquid and gas. Since these are prior art, they will not be described in detail here.

[0030] The liquid hourglass 8 in this invention is existing technology, and its structure and liquid contents will not be described in detail here.

[0031] This invention features a novel concept, ingenious structure, convenient operation, and strong practicality. When the patient presses down the control lever and blows air, it simultaneously triggers the sealing plate to open the air inlet slot, the sealing block to open the connecting slot, and the conical block to open the liquid hourglass timing channel. This allows the blown air to enter the reservoir, generating visible bubbles for the patient to monitor the stability of the blowing. Simultaneously, the liquid hourglass starts a visual timing function. The blowing airflow pushes a lightweight plate to move. After blowing, the moving lever resets, causing the moving pawl to drive the ratchet and pointer to rotate one increment, achieving automatic and accurate counting and completely avoiding errors caused by the patient's subjective estimation of time and number of breaths. By adjusting the spacing of the flow dividers, the airflow distribution ratio can be changed, thus flexibly adjusting the blowing resistance to meet the needs of progressive intensity training from the early to the later stages of rehabilitation. The entire device integrates training, timing, counting, and resistance adjustment into one compact, seamless, and portable unit. The liquid hourglass and pointer can be reset and reused, greatly improving the standardization and data traceability of the training process, facilitating objective evaluation of rehabilitation effects by medical staff, and enhancing patient motivation and compliance through intuitive feedback, effectively promoting efficient respiratory function rehabilitation.

[0032] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0033] It is evident that the portable respiratory function trainer provided by this invention can effectively solve the problem that existing respiratory training devices have limited functionality and cannot meet training needs. This structure is simple to operate, convenient to use, and improves training efficiency.
