Abstract
Description
Technical Field
[0001] This invention relates to the field of medical assistive device technology, specifically to a respiratory training assistive device for critically ill patients. Background Technology
[0002] In the rehabilitation treatment of critical care medicine patients, breathing training is an important part of helping patients restore lung function and improve ventilation. Critically ill patients who have been bedridden or under respiratory support treatment for a long time often have problems such as respiratory muscle weakness, decreased lung compliance and insufficient breathing depth. In order to promote lung rehabilitation, it is usually necessary to assist patients in performing regular inhalation exercises through breathing training devices to improve breathing efficiency and vital capacity.
[0003] Most existing breathing training devices are mechanical in structure, typically consisting of an airflow channel, a float indicator, and an oral interface. Patients inhale to raise the float, thereby understanding their inhalation strength and duration. While these devices can achieve basic breathing training functions, they still have some shortcomings in practical use.
[0004] First, the connection points are not very stable. The connecting tubes and the main body are prone to loosening or falling off during repeated use, affecting the continuity and sealing of training. Second, the inspiratory resistance of some devices is not adjustable, making it impossible to personalize the settings according to the different rehabilitation stages or lung function differences of different patients, thus limiting the training effect. In addition, traditional devices often require patients or caregivers to hold them by hand, which is inconvenient to fix. After a while, the use will increase the burden on the upper limbs and affect the patient's cooperation. Although some devices have clamping structures, they are mostly manually screw-fixed, which is cumbersome to operate and lacks stability, thus affecting the standardization and effectiveness of training. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a respiratory training aid for critical care patients, which solves the problems of poor stability of the connection parts, and the tendency for the connecting tube to loosen or detach from the main body during repeated use, affecting the continuity and sealing of training.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a respiratory training assist device for critically ill patients, comprising a housing, with spheres installed on both sides inside the housing, a connector fixedly connected to the left side outside the housing, a connecting tube inside the connector, an anti-detachment mechanism inside the connector, an adjusting tube installed in the middle of the connecting tube, a resistance adjusting mechanism outside the adjusting tube, an mounting head installed at the bottom of the connecting tube, a mouthpiece installed inside the mounting head, a support frame fixedly connected to the top of the housing, a support plate fixedly connected to the top of the support frame, an mounting mechanism inside the support plate, and a fixing block fixedly connected to the rear side outside the housing, with a fixing mechanism inside the fixing block. The anti-detachment mechanism includes arc-shaped blocks, which are slidably connected to the inner sides of the connector. Each of the two arc-shaped blocks has a protrusion fixedly connected to its top, and each of the two arc-shaped blocks has an insert fixedly connected to its outer side.

[0008] Preferably, the fixing mechanism includes a micro motor, which is fixedly connected to the top of the fixing block. A reciprocating lead screw is fixedly connected to the output end of the micro motor. The reciprocating lead screw is rotatably connected inside the fixing block. A lifting block is threaded to the outside of the reciprocating lead screw. Guide blocks are fixedly connected to both sides of the lifting block. Connecting rods are fixedly connected inside the two guide blocks. The two connecting rods are slidably connected inside the fixing block. Connecting blocks are fixedly connected to the bottom of the two connecting rods. A clamping plate is installed on the outside of the connecting blocks.
[0009] Preferably, the installation mechanism includes fixed rods, which are fixedly connected to the inner sides of the support plate. Movable blocks are slidably connected to the outer sides of the two fixed rods. Second springs are fixedly connected to the outer sides of the two movable blocks. Multiple second springs are sleeved on the outer sides of the two fixed rods. Extension rods are fixedly connected to the outer sides of the two movable blocks. Fixed plates are fixedly connected to the top of the multiple extension rods.
[0010] Preferably, the connector has a sliding hole on its exterior, the two protrusions are slidably connected inside the sliding hole, the two positioning blocks each have a slot inside, and the two inserts are inserted into the two slots.
[0011] Preferably, the extension block has limit holes on both sides inside, and the limit pin is inserted into any of the limit holes.
[0012] Preferably, the connecting block is connected to the clamping plate by bolts.
[0013] Preferably, both of the fixing plates are provided with protective plates on their exteriors, and both protective plates are made of rubber.
[0014] Preferably, the mounting head has a threaded hole inside, and the bottom of the bite is threadedly connected to the threaded hole.
[0015] Preferably, an arc-shaped clamp is fixedly connected to the outer right side of the housing, the connecting tube is disposed inside the arc-shaped clamp, and anti-slip pads are fixedly connected to both sides of the bottom of the housing.
[0016] Working principle: In use, the two protrusions are first moved relative to each other. As the two protrusions move relative to each other, the two arc-shaped blocks fixed at the bottom also move relative to each other. This movement of the arc-shaped blocks compresses the first spring fixed at the center, causing it to deform. Then, as the two arc-shaped blocks move relative to each other, they also move the two externally fixed inserts relative to each other, causing the two inserts to disengage from the two pre-set holes inside the connecting block. The connecting tube is then removed, and the top of the connecting tube is inserted into the connector. At this time, the positioning blocks fixed on both sides of the top of the connector simultaneously insert into the pre-set holes on both sides of the connector. Finally, the two protrusions are released, and under the reaction force of the first spring, the two inserts return to their original positions and insert into the connecting block. The two slots inside the positioning block are used to guide the breathing training aid. When using this breathing training aid, first, move the baffle upward to fully expose the inside of the adjustment tube. Then, insert the limiting pin into the corresponding limiting hole. At this time, the patient bites down on the mouthpiece. When the patient inhales, the lightweight sphere in each air chamber of the shell will be lifted by the airflow generated by the inhalation. By observing the height and duration of the sphere's rise, the patient can intuitively understand their inhalation strength and lung capacity, thereby conducting breathing training. This device also facilitates the reinforcement of the connection strength of the connector and connecting tube when using the breathing training aid, preventing the connector and connecting tube from falling off during use, and ensuring the accuracy of the inhalation resistance and the training effect. When it is necessary to adjust the inspiratory resistance of the device, first disengage the limiting pin from the inside of the limiting hole, then move the extension plate downward. As the extension plate moves downward, the baffle moves downward with it. As the baffle moves downward, it will gradually cover the inside of the adjustment tube. When the appropriate resistance is reached, insert the limiting pin into the corresponding limiting hole to complete the resistance adjustment operation. This allows the user to easily adjust the inspiratory resistance manually according to their needs when using the breathing training device, flexibly adjust the inspiratory resistance to meet different rehabilitation needs, and improve the practicality of the device. When it is necessary to fix the device to the edge of the table, first start the micro motor. The micro motor drives the reciprocating screw fixedly connected to the output end to rotate. The rotation of the reciprocating screw causes the lifting block connected to the external thread to move downward. The movement of the lifting block causes the two guide blocks fixedly connected to the two external sides to move downward. The movement of the two guide blocks causes the two connecting rods fixedly connected to the inside to move downward. The movement of the two connecting rods causes the connecting block fixedly connected to the bottom to move downward. The movement of the connecting block causes the externally mounted clamping plate to move downward, so that the clamping plate is separated from the bottom of the shell and the installation gap is exposed. Then, place the bottom of the shell on the edge of the table and then start the micro motor again. The micro motor drives the reciprocating screw to reverse. The reciprocating screw reverses and causes the lifting block and the two guide blocks to move upward. The movement of the two guide blocks causes the connecting blocks fixedly connected to the bottom of the two connecting rods to move upward. The movement of the connecting blocks causes the clamping plate to move upward, so that the clamping plate contacts the bottom of the edge of the table. Then, turn off the micro motor. At this time, the device is fixed to the edge of the table. This makes it easy to fix the device to the edge of the table when using the breathing assist training device, so that the user does not need to hold it, reducing the burden on the arm muscles and improving the comfort of use. When it is necessary to fix the display device to the breathing assist training device, first move the protective plates to both sides. The movement of the two protective plates moves the two fixed plates to both sides. When the two fixed plates move to both sides, they also move multiple extension rods to both sides. When the multiple extension rods move to both sides, they move the two moving blocks fixed at the bottom to both sides of the two fixed rods. When the two moving blocks move, they compress the two second springs fixed to both sides of the outside, causing the second springs to deform under force. Then, after the two fixed plates separate by a certain distance, place the display device in the middle of the two protective plates. Then, release the two fixed plates. Under the reaction force of the second springs, the two protective plates move relative to each other and fix the display device. This makes it easy to fix the display device to the upper part of the device when using the breathing assist training device, helping patients better understand and master the correct breathing training method and improving the training effect.
[0017] This invention provides a respiratory training aid for critically ill patients. It has the following beneficial effects: 1. When using this breathing training device, first move the two protrusions relative to each other, causing the bottom arc block to squeeze the first spring, so that the insert block disengages from the hole of the connecting block, and the connecting tube can be removed. During installation, insert the connecting tube into the connector, and its top positioning block is simultaneously inserted into the corresponding hole. After releasing the protrusions, the first spring resets the insert block and inserts it into the slot of the positioning block, thereby strengthening the connection. During training, move the baffle upward to expose the adjustment tube, insert the limiting nail to fix it, and the patient bites the mouthpiece to inhale. The airflow lifts the lightweight spheres in each air chamber inside the shell. By observing the height and duration of the sphere's rise, you can intuitively understand the inhalation force and vital capacity, and carry out effective breathing training.
[0018] 2. To adjust the inspiratory resistance, first pull the limiting pin out of the limiting hole, then move the extension plate downwards, causing it to move the baffle downwards, gradually blocking the internal channel of the adjusting tube. When the baffle reaches the desired resistance, reinsert the limiting pin into the corresponding limiting hole to fix it, thus completing the adjustment. This design allows users to manually and flexibly adjust the inspiratory resistance according to their own rehabilitation needs, effectively improving the practicality of the device.
[0019] 3. When the device needs to be fixed to the edge of the desktop, start the micro motor to drive the reciprocating screw to rotate. This causes the lifting block to drive the bottom connecting block and clamping plate to move down through the guide block and connecting rod, thus creating an installation gap at the bottom of the housing. After placing the housing on the edge of the desktop, start the micro motor again to reverse the direction, causing the clamping plate to move up and make tight contact with the bottom of the desktop. Then, turn off the motor to complete the fixation. This design allows the device to be stably fixed to the edge of the desktop without the need for hand-holding, reducing the burden on the user's arms and improving the comfort of use.
[0020] 4. When it is necessary to fix the display device, move the protective plates to both sides, causing the fixing plate, extension rod, and moving block to move outward simultaneously. This compresses and deforms the second spring, placing the display device between the two protective plates. Release the fixing plate; the rebound force of the second spring will push the protective plates to move relative to each other, thus clamping the display device. This design allows patients to securely install the display device on the upper part of the device during training, helping them to more intuitively grasp the breathing method and improve training effectiveness.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Example: Please see the appendix Figure 1 - Appendix Figure 10This invention provides a respiratory training aid for critical care patients, comprising a housing 1, with spheres 2 installed on both sides inside the housing 1. The spheres 2 help patients understand the depth and frequency of their breathing; for example, the spheres 2 may change with the intensity and speed of airflow as air passes through, providing visual feedback and encouraging patients to complete deep breathing training. A connector 3 is fixedly connected to the left side of the housing 1, with a connecting tube 4 inside the connector 3 and an anti-dislodgement mechanism 9 inside the connector 3. An adjustment tube 5 is installed in the middle of the connecting tube 4, with a resistance adjustment mechanism 13 outside the adjustment tube 5. An installation head 7 is installed at the bottom of the connecting tube 4, with a mouthpiece 8 inside the installation head 7. The mouthpiece 8 helps patients maintain the correct mouth posture, making breathing movements more standardized and avoiding ineffective training due to mouth opening or position deviation. A support frame 17 is fixedly connected to the top of the housing 1. The top of the housing 7 is fixedly connected to a support plate 18, and the support plate 18 is provided with an installation mechanism 19. The installation mechanism 19 is used to fix a tablet or mobile phone, which helps patients better master the breathing training method. The outer rear side of the housing 1 is fixedly connected to a fixing block 15, and the fixing block 15 is provided with a fixing mechanism 16. The fixing mechanism 16 is used to fix the device in the use position, so that the user does not need to hold it, which improves the comfort of use. The installation head 7 has a threaded hole 20 inside, and the bottom of the mouthpiece 8 is threadedly connected to the threaded hole 20, which facilitates the replacement or cleaning of the mouthpiece 8. The outer right side of the housing 1 is fixedly connected to an arc-shaped clip 6, and the connecting tube 4 is set inside the arc-shaped clip 6. The arc-shaped clip 6 is used to fix the connecting tube 4. The bottom two sides of the housing 1 are fixedly connected to anti-slip pads 21, which improves the stability of the device when placed on the table. The anti-detachment mechanism 9 includes arc-shaped blocks 901, which are slidably connected to the inner sides of the connector 3. Each of the two arc-shaped blocks 901 has a protrusion 902 fixedly connected to its top. The protrusions 902 facilitate operation. Each of the two arc-shaped blocks 901 has an insert 903 fixedly connected to its outer side. A first spring 904 is fixedly connected to the middle of each of the two arc-shaped blocks 901. Positioning blocks 12 are fixedly connected to both outer sides of the connector 4. The two positioning blocks 12 are located on the inner sides of the connector 3. A sliding hole 11 is provided on the outer side of the connector 3. The two protrusions 902 are slidably connected inside the sliding hole 11. The sliding hole 11 facilitates the movement of the protrusions 902. Each of the two positioning blocks 12 has a slot 10 inside. The two inserts 903 are inserted into the two slots 10, improving the stability of the connector 4 and connector 3 installation.
[0025] Specifically, during the use of this breathing training aid, the two protrusions 902 are first moved relative to each other, causing the two arc-shaped blocks 901 fixedly connected to their bottoms to move relative to each other synchronously. This creates a compressive force on the first spring 904 fixedly connected in the middle, causing the first spring 904 to deform and store elastic potential energy. As the two arc-shaped blocks 901 move relative to each other, the two externally fixedly connected inserts 903 also move and gradually disengage from the pre-set holes inside the connector 3. Then, the connecting tube 4 is removed, and its top is inserted into the connector 3. During this process, the positioning blocks 12 fixedly connected to both sides of the top of the connector 3 will insert into the pre-set holes on both sides inside the connector 3, achieving a stable connection. At this point, the two protrusions 902 are released, and under the reaction force of the first spring 904, the two inserts 903 will automatically reset and insert into the positioning blocks 12. The two slots 10 are used to fix the device, which significantly improves the connection stability between the connector 3 and the connecting tube 4, prevents it from falling off during use, and ensures the airtightness and safety of the device. In actual training, the patient first pushes the baffle 1304 upward to fully expose the inside of the regulating tube 5, and then inserts the limiting pin 1303 into the corresponding limiting hole 14 to fix the position. After the patient bites the mouthpiece 8, he begins to perform inhalation training. The lightweight spheres 2 in the multiple air chambers inside the shell 1 will be lifted by the inhalation airflow. The height and suspension time of the spheres 2 can intuitively reflect the patient's inhalation strength and vital capacity level, thereby helping the patient to assess his own breathing ability and training effect. This design not only achieves high strength and reliability of structural connection, but also makes the training process more intuitive and improves the practicality and effectiveness of breathing training.
[0026] Please see the appendix Figure 3 - Appendix Figure 11 The resistance adjustment mechanism 13 includes a mounting plate 1301, which is fixedly connected to the top of the adjustment tube 5. A U-shaped plate 1302 is fixedly connected to the outside of the mounting plate 1301. A limit pin 1303 is slidably connected to the outside of the U-shaped plate 1302. A baffle 1304 is slidably connected inside the adjustment tube 5. The baffle 1304 facilitates the adjustment of the resistance during breathing training. An extension block 1305 is fixedly connected to the top of the baffle 1304. Limit holes 14 are opened on both sides inside the extension block 1305. The limit pin 1303 is inserted into any of the limit holes 14 to facilitate the adjustment of the position of the baffle 1304 inside the adjustment tube 5. Specifically, when adjusting the inspiratory resistance of the breathing training aid, the operator first pulls the limiting pin 1303 out of the limiting hole 14, making the adjustment mechanism movable. Then, the extension block 1305 is slowly moved downwards. During the downward movement, the extension block 1305 drives the baffle 1304, which is fixedly connected to it, to move downwards simultaneously. As the baffle 1304 gradually moves downwards, it gradually blocks the internal channel of the adjustment tube 5, thereby effectively reducing the airflow cross-sectional area and increasing the airflow resistance during inhalation. When the device is moved to the ideal position and the required inspiratory resistance is achieved, the limiting pin 1303 is reinserted into the corresponding limiting hole 14 to lock the height of the baffle 1304, thus completing the precise adjustment of the inspiratory resistance. Through this structural design, users can flexibly adjust the inspiratory resistance according to their individual lung function, rehabilitation stage, or training goals, making the training process more personalized. This adjustment method is simple to operate, improves the operability and adaptability of the device, and can also help patients gradually strengthen their respiratory muscle groups, improve lung capacity, and enhance the overall effect of rehabilitation training.
[0027] Please see the appendix Figure 1 - Appendix Figure 12 The fixing mechanism 16 includes a micro motor 1601, which is fixedly connected to the top of the fixing block 15. A reciprocating screw 1602 is fixedly connected to the output end of the micro motor 1601. The reciprocating screw 1602 is rotatably connected inside the fixing block 15. A lifting block 1603 is threadedly connected to the outside of the reciprocating screw 1602. Guide blocks 1604 are fixedly connected to both sides of the lifting block 1603. Connecting rods 1605 are fixedly connected inside the two guide blocks 1604. The two connecting rods 1605 are slidably connected inside the fixing block 15. Connecting blocks 1606 are fixedly connected to the bottom of the two connecting rods 1605. A clamping plate 1607 is installed on the outside of the connecting block 1606. The clamping plate 1607 facilitates fixing the device to the edge of the table or other objects. The connecting block 1606 is connected to the clamping plate 1607 by bolts 1608, which facilitates the replacement of the clamping plate 1607.
[0028] Specifically, when it is necessary to securely fix the breathing training aid to the edge of the table, firstly, start the micro motor 1601. The micro motor 1601 starts to rotate and drives the reciprocating screw 1602 fixedly connected to its output end to rotate synchronously. As the reciprocating screw 1602 rotates, the lifting block 1603 externally threaded to it moves downward along the screw thread direction. During the downward movement, the lifting block 1603 drives the guide blocks 1604 fixedly connected on both sides to move downward together. When the two guide blocks 1604 continue to move downward, they will drive the connecting rod 1605 fixedly connected internally to move downward synchronously, thereby causing the connecting block 1606 fixedly connected at the bottom to move downward as a whole. As the connecting block 1606 moves downward, it drives the externally installed clamping plate 1607 to move downward, so that the clamping plate 1607 gradually separates from the bottom of the housing 1 and exposes an appropriate installation gap. At this time, the bottom of the housing 1 can be... The device is accurately placed above the edge of the desktop. Then, the micro motor 1601 is restarted to rotate in the opposite direction, driving the reciprocating screw 1602 to rotate in the opposite direction. As the reciprocating screw 1602 rotates in the opposite direction, the lifting block 1603 begins to move upward, simultaneously driving the guide block 1604, connecting rod 1605, and connecting block 1606 to rise in sequence, finally causing the clamping plate 1607 to move up to a position that is in close contact with the bottom edge of the desktop. At this point, the micro motor 1601 is turned off, and the clamping plate 1607 firmly fixes the device to the edge of the desktop, achieving stable support. This design is compact and easy to operate. By replacing the traditional manual clamping method with electric control, it not only improves the installation efficiency and stability of the device, but also reduces the burden on the user's hands and arms during training, allowing patients to focus more on breathing training operations and improving the comfort and practicality of the device during training.
[0029] Please see the appendix Figure 4 - Appendix Figure 12 The installation mechanism 19 includes fixed rods 1901, which are fixedly connected to the inner sides of the support plate 18. Movable blocks 1902 are slidably connected to the outer sides of both fixed rods 1901. Second springs 1903 are fixedly connected to the outer sides of both movable blocks 1902. Multiple second springs 1903 are sleeved on the outer sides of the two fixed rods 1901. Extension rods 1904 are fixedly connected to the outer sides of both movable blocks 1902. Fixed plates 1905 are fixedly connected to the tops of the multiple extension rods 1904. The fixed plates 1905 facilitate the fixing of mobile phones or tablets. Protective plates 1906 are provided on the outer sides of both fixed plates 1905. Both protective plates 1906 are made of rubber, which effectively prevents the equipment casing from being scratched by the hard fixed plates 1905, extending the equipment's service life.
[0030] Specifically, when the display device needs to be securely installed above the breathing assistance training device, the protective plates 1906 on both sides should first be pushed outwards by hand. During this movement, the protective plates 1906 will cause the two fixed plates 1905 connected to their outer sides to simultaneously unfold to both sides. As the fixed plates 1905 separate, the multiple extension rods 1904 connected inside are also pulled to both sides. The two moving blocks 1902 fixedly connected to the bottom of the extension rods 1904 will slide outwards along a sliding trajectory outside the two fixed rods 1901. During this outward movement, the moving blocks 1902 will gradually compress the two second springs 1903 fixedly connected to their outer sides, causing the second springs 1903 to deform and store energy. Once the fixed plates 1905 have separated to a sufficient distance... The display device is then securely positioned in the center between the two protective plates 1906. The fixing plate 1905 is then released, and under the elastic restoring force of the second spring 1903, the moving block 1902 causes the extension rod 1904, the fixing plate 1905, and the protective plate 1906 to retract inwards, allowing the protective plate 1906 to adhere to the side wall of the display device, thus firmly clamping and fixing it to the device. This structure allows for quick assembly and disassembly without additional tools, ensuring safe and convenient operation. It also allows the display device to be stably positioned on the upper part of the device, facilitating real-time viewing of instructional videos or operational prompts during training. This provides a more intuitive understanding of breathing rhythm, posture, and intensity requirements, improving the clarity and effectiveness of training guidance and offering more convenient auxiliary support for rehabilitation training.
