Technical Field
[0001] This invention relates to the field of medical and nursing experimental technology, specifically to a breathing and expectoration exercise model based on medical and nursing experiments. Background Technology
[0002] In medical nursing trials, a “breathing and expectoration practice model” typically refers to a simulation system or method used to train healthcare professionals or patients in effective breathing and expectoration techniques. These models are designed to mimic the human respiratory system, particularly the airways and lungs, to help learn and practice techniques for clearing respiratory secretions such as sputum.
[0003] In medical and nursing teaching and clinical practice, sputum is mainly collected by connecting a suction machine to a suction tube and inserting the tube through the patient's mouth. However, various factors can cause different patient reactions during tube insertion, leading to varying sputum expectoration outcomes. Postural drainage is an important method to promote sputum expectoration. Its core principle is to use gravity to drain secretions from specific lung segments into the large airways for clearance through coughing or suctioning. If the breathing and expectoration practice model has a fixed position, it cannot simulate the precise tilt angles required for drainage of different lung segments, severely affecting the authenticity and effectiveness of teaching and training. Existing breathing and expectoration practice models used in medical and nursing experiments have relatively fixed placement positions, making it impossible to practice the need to simulate the tilt angles required for drainage of different lung segments. If the tilt angle is too large, it will exacerbate patient discomfort. For example, a head-down, feet-up position... Excessive tilt angle (e.g., exceeding 30°) can cause dizziness, nausea, facial congestion, and increased intraocular pressure, posing a higher risk, especially to the elderly or patients with cardiovascular disease, and is accompanied by an increased risk of intracranial pressure. Too large a tilt angle may increase cerebral blood flow and intracranial pressure, posing a danger to patients with traumatic brain injury, hypertension, or glaucoma. Conversely, if the tilt angle is too small, insufficient gravity prevents sputum from effectively flowing to the central airway, significantly reducing sputum expectoration efficiency. Furthermore, when patients experience shortness of breath during sputum suction, it can also affect the suction effect. Violent coughing during sputum suction can also cause swaying, further impacting the suction effect. Existing sputum suction practice models have limited functionality and cannot provide coping strategies for different situations encountered by the trainee. Therefore, we propose a breathing and sputum suction practice model based on medical nursing trials. Summary of the Invention
[0004] The purpose of this invention is to provide a breathing and expectoration exercise model based on medical nursing trials, to address the issues raised in the background art where the model's placement is relatively fixed, making it impossible to practice. This necessitates simulating the tilt angle required for drainage of different lung segments. Excessive tilt angles can exacerbate patient discomfort. A large head-down, feet-up angle (e.g., exceeding 30°) can cause dizziness, nausea, facial congestion, and increased intraocular pressure, posing a higher risk, especially to elderly patients or those with cardiovascular disease, and is associated with increased intracranial pressure. An excessively large head-down angle may also increase cerebral blood flow and intracranial pressure. High tilt angles pose a risk to patients with traumatic brain injury, hypertension, or glaucoma. If the tilt angle is too small, insufficient gravity will prevent sputum from flowing effectively to the central airway, significantly reducing sputum expectoration efficiency. Furthermore, when patients experience shortness of breath during sputum suction, it can also affect the suction effect. In addition, patients may cough violently during sputum suction, causing them to sway, which can also affect the suction effect. Existing sputum suction practice models have limited functionality and cannot address the issue of coping strategies for different situations encountered by the trainees.

The side of each of the two second springs away from the vibration limiting block is fixedly connected to the fixed groove plate. A hemispherical shell is fixedly connected to one side of the vibration limiting block. A sphere is set inside the hemispherical shell. The telescopic end of a telescopic rod is fixedly connected to one side of the sphere. A flexible tube is fixedly connected to one side of the telescopic rod. The flexible tube is fixedly connected to the fixed box. An inertial ball is set inside the flexible tube. A flexible rod is slidably connected inside the flexible tube. An iron limiting block is fixedly connected to one side of the flexible rod. The outer side of the flexible rod is fixedly connected to the connecting plate.
[0012] The iron limiting block is slidably connected to the fixed box, and a second electromagnet is fixedly connected inside the fixed box.

[0015] This invention has at least the following beneficial effects: By incorporating an angle-adjustable vibration mechanism, the model body on top of the flipping plate can be adjusted to the required angle for sputum clearance practice. This angle adjustment allows for the simulation of various clinical drainage postures, enhancing the training's relevance and realism. Furthermore, the first vibration motor can simulate the impact of severe patient movement on other sputum clearance exercises, enabling trainees to temporarily face different situations. The inclusion of a sputum discharge adjustment mechanism and a discharge power drive mechanism allows the discharge power drive to activate the sputum discharge adjustment mechanism, and, in conjunction with the angle-adjustable vibration mechanism, to randomly adjust sputum discharge at different positions.

This can be used to simulate the phenomenon when the patient's breathing fluctuations are severe and affect sputum extraction. Furthermore, through the cooperation of the above mechanisms, the system can enhance the comprehensiveness of the sputum discharge exercise model's functional simulation and provide practitioners with simulations of different situations.

[0018] 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.
[0019] Example 1 Please see Figures 1 to 9 The present invention provides a technical solution: a breathing and expectoration exercise model based on medical nursing experiment, comprising: a base 1, a flip plate 6, a fixing box 7 and a model body 8, wherein the flip plate 6 is rotatably connected to the top of the base 1, the model body 8 is fixedly connected to the top of the flip plate 6, and the fixing box 7 is fixedly connected to one side of the flip plate 6. It also includes: an angle-adjustable vibration mechanism 2, which is set between the base 1 and the flip plate 6. The flip plate 6 is used to adjust the exercise angle according to the needs of the breathing and expectoration exercise, and to cooperate with the exercise to simulate the cough state. The sputum discharge adjustment mechanism 3 is set between the fixed box 7 and the model body 8. The sputum discharge adjustment mechanism 3 is used to randomly discharge the amount of sputum. The discharge power drive mechanism 4 is located between the fixed box 7 and the sputum discharge adjustment mechanism 3. The discharge power drive mechanism 4 is used to cooperate with the angle adjustment vibration mechanism 2 to simulate cough vibration and drive the sputum discharge adjustment mechanism 3 to discharge sputum. The breathing simulation mechanism 5 is located between the fixed box 7 and the emission power drive mechanism 4. The breathing simulation mechanism 5 is used to simulate the random breathing frequency by simulating the cough vibration driven by the emission power drive mechanism 4.
[0020] The above-mentioned angle-adjustable vibration mechanism 2 allows the model body 8 on top of the flip plate 6 to be adjusted to the required angle position for sputum drainage practice. By adjusting the angle, various clinical drainage postures can be simulated, enhancing the relevance and realism of the training. Furthermore, the first vibration motor can simulate the different effects of severe shaking of the patient's body on other sputum drainage exercises, allowing trainees to temporarily face different situations. The sputum discharge adjustment mechanism 3 and the discharge power drive mechanism 4 enable the discharge power drive mechanism 4 to drive the sputum discharge adjustment mechanism 3 to discharge sputum, and this, in conjunction with the angle-adjustable vibration mechanism 2, completes random discharge. Different amounts of sputum are randomly discharged at different times. The discharge power drive mechanism 4, combined with mechanical vibration and flexible transmission, realistically simulates the chest vibration and airflow impact during coughing, effectively promoting sputum discharge and enhancing the randomness of the exercise to improve the practitioner's experience. By setting up a breathing simulation mechanism 5, the entire process of "breathing-coughing-sputum discharge" can be coordinated through the mechanical linkage of the discharge power drive mechanism 4, restoring the real physiological process. This can be used to simulate the phenomenon when the patient's breathing fluctuates violently and affects sputum extraction. Furthermore, through the cooperation between the above mechanisms, the comprehensiveness of the sputum discharge exercise model can be enhanced, and different simulations can be provided for the practitioner.
[0021] The angle-adjustable vibration mechanism 2 includes a first limiting groove 21 opened in the base 1. A first motor 22 is fixedly connected to the inner wall of the first limiting groove 21. A reciprocating screw 23 is fixedly connected to the output end of the first motor 22. A threaded moving table 24 is threadedly connected to the outer side of the reciprocating screw 23. The threaded moving table 24 is slidably connected to the first limiting groove 21. Rotary connecting blocks 25 are rotatably connected to both the threaded moving table 24 and the interior of the flip plate 6. A first fixing tube 26 is fixedly connected to one side of one of the rotating connecting blocks 25. A first iron slider 210 is slidably connected to the inner side of the first fixing tube 26. A first connecting rod 27 is fixedly connected to one side of the first iron slider 210. One end of the first connecting rod 27 is fixedly connected to another threaded moving table 24. A first spring 28 is fixedly connected between the two threaded moving tables 24. A first vibration motor 29 is fixedly connected to the bottom of the flip plate 6. A first electromagnet 211 is fixedly connected to the interior of the first fixing tube 26. When the model body 8 is adjusted to the required practice angle according to the needs of the exercise, the first motor 22 is controlled to rotate the reciprocating screw 23, causing the rotating reciprocating screw 23 to drive the threaded moving stage 24 to slide within the first limiting groove 21. When the threaded moving stage 24 moves closer to the first motor 22, the model body 8 is lowered. When the threaded moving stage 24 moves away from the first motor 22, the model body 8 can be lifted. The moving threaded moving stage 24 is coordinated with the first fixed tube 26 and the first connecting rod 27, and with the spring 28, the model body 8 is lifted. Under the action of the vibration, the model body 8 can be adjusted to the required angle. When it is necessary to simulate the state of a patient coughing violently, the first vibration motor 29 is controlled to run, so that the flip plate 6 vibrates up and down. The first iron slider 210 at one end of the first connecting rod 27 slides and is limited in the first fixed tube 26. Vibration is performed under the elastic action of the first spring 28. When it is necessary to fix the position of the model body 8, the first electromagnet 211 is energized, so that the energized first electromagnet 211 attracts the first iron slider 210 and fixes it, thereby fixing the position of the model body 8.
[0022] The sputum discharge regulating mechanism 3 includes a storage cylinder 31 fixedly connected to the inside of the fixed box 7. A piston 32 is slidably connected inside the storage cylinder 31. A connecting rod 33 is fixedly connected to one side of the piston 32. A connecting plate 37 is fixedly connected to one side of the connecting rod 33. A first solenoid valve 34 is fixedly connected to one side of the storage cylinder 31. A first connecting pipe 35 is fixedly connected to the side of the first solenoid valve 34 away from the storage cylinder 31. The first connecting pipe 35 is connected to the air pipe inside the model body 8. A vibration touch switch 36 is fixedly connected to the inside of the air pipe inside the model body 8. When the suction tube is inserted into the model body 8, the suction tube will touch the vibration touch switch 36 to provide feedback, which will cause the first vibration motor 29 to vibrate. When the structure inside the discharge power drive mechanism 4 drives the connecting plate 37, the moving connecting plate 37 will drive the piston 32 at one end of the connecting rod 33 to move. The moving piston 32 slides in the storage cylinder 31, and the simulated sputum liquid in the storage cylinder 31 can be pushed out through the piston 32, and the first solenoid valve 34 will be opened in advance. Then the simulated sputum liquid can be transported into the trachea inside the model body 8 through the first connecting pipe 35, and then suctioned out through the suction tube to the external suction machine.
[0023] The emission power drive mechanism 4 includes a fixed groove plate 41 fixedly connected to the inner side of the fixed box 7. A vibration limiting block 42 is slidably connected inside the fixed groove plate 41. A second spring 43 is fixedly connected to the top and bottom of the vibration limiting block 42. The sides of the two second springs 43 away from the vibration limiting block 42 are fixedly connected to the fixed groove plate 41. A hemispherical shell 44 is fixedly connected to one side of the vibration limiting block 42. A sphere 45 is provided inside the hemispherical shell 44. The telescopic end of a telescopic rod 46 is fixedly connected to one side of the sphere 45. A flexible tube 47 is fixedly connected to one side of the telescopic rod 46. The flexible tube 47 is connected to the fixed groove plate 7. The fixed box 7 is fixedly connected. An inertial ball 48 is set inside the flexible tube 47. A flexible rod 49 is slidably connected inside the flexible tube 47. An iron limiting block 410 is fixedly connected to one side of the flexible rod 49. The outer side of the flexible rod 49 is fixedly connected to the connecting plate 37. The iron limiting block 410 is slidably connected to the fixed box 7. A second electromagnet 411 is fixedly connected inside the fixed box 7. The second electromagnet 411 is located above the iron limiting block 410. A second vibration motor 412 is fixedly connected inside the vibration limiting block 42. A power light touch switch 413 is fixedly connected to the inner side of the air pipe inside the model body 8. When the suction catheter is inserted and the power touch switch 413 is triggered, the angle position within the angle adjustment vibration mechanism 2 is fixed. The second vibration motor 412 is controlled via feedback from the power touch switch 413, causing the vertically moving vibration limit block 42 to slide within the fixed groove plate 41. As the vibration limit block 42 moves, it compresses or stretches the second spring 43. The hemispherical shell 44 on the vibration limit block 42 drives the internal ball 45, which, under the action of the telescopic rod 46, causes the connecting plate 37 to bend vertically. During bending, this causes the inertial... The inertial ball 48 moves, and the inertial ball 48 pushes the flexible rod 49 to move, which in turn causes the moving flexible rod 49 to drive the iron limiting block 410 to slide and limit within the fixed box 7. When the iron limiting block 410 moves, it can drive the connecting plate 37, which in turn can drive the internal structure of the sputum discharge adjustment mechanism 3 to discharge simulated sputum liquid. When the position of the sputum discharge adjustment mechanism 3 needs to be fixed, the second electromagnet 411 can be energized to attract the iron limiting block 410 and fix its position. At this time, the breathing simulation mechanism 5 can work independently.
[0024] Example 2 like Figures 1 to 6 In this second embodiment, the other structures remain unchanged, but the difference from the first embodiment is: The breathing simulation mechanism 5 includes a gear 52 rotatably connected to the bottom of the fixed box 7; a rack 51 meshing with one side of the vibration limiting block 42; the rack 51 being fixedly connected to the bottom of the vibration limiting block 42; a drive shaft 53 fixedly connected to one side of the gear 52; a hollow plate 54 slidably connected to the outer side of the drive shaft 53; a fixed tube 55 fixedly connected to the bottom of the fixed box 7; a compression rod 56 slidably connected to the inner side of the fixed tube 55; and the compression rod 56 being fixedly connected to the hollow plate 54. An inflatable airbag 57 is fixedly connected to one side of the model body 8. The end of the inflatable airbag 57 away from the compression rod 56 is fixedly connected to the inside of the fixed tube 55. A second solenoid valve 58 is fixedly connected to one side of the fixed tube 55. A breathing tube 59 is fixedly connected to the side of the second solenoid valve 58 away from the inflatable airbag 57. An inflatable airbag 510 is fixedly connected inside the model body 8. The inflatable airbag 510 is located outside the trachea inside the model body 8. A breathing touch switch 511 is fixedly connected to the inside of the trachea inside the model body 8. In use, when the second electromagnet 411 operates independently through the breathing simulation mechanism 5, the suction tube touches the breathing touch switch 511, which in turn causes the second vibration motor 412 inside the vibration limiting block 42 to run. This causes the vibration limiting block 42 to slide up and down within the fixed slot plate 41. The second spring 43 ensures that the up and down movement of the vibration limiting block 42 is limited. When the vibration limiting block 42 moves, it drives the rack 51 to move up and down. The moving rack 51 drives the gear 52 to rotate. The rotating gear 52 drives the hollow plate 54 through the drive shaft 53. The drive shaft 53 can move the hollow plate 54 away from or towards the fixed tube 55. The hollow plate 54 can drive the squeezing rod 56 to move. When the hollow plate 54 is close to the fixed tube 55, the squeezing rod 56 can push out the gas in the inflatable bag 57 in advance. Opening the second solenoid valve 58 allows gas to be delivered into the inflatable bladder 510 via the breathing tube 59. The inflatable bladder 510 simulates the patient's violent breathing and deforms the trachea within the model body 8 to change the position of sputum within the trachea. When the drive shaft 53 moves away from the fixed tube 55, it moves the hollow plate 54 away from the fixed tube 55, causing the squeezing rod 56 to drive the inflatable bladder 57 to extract the gas from the inflatable bladder 510. This causes the inflatable bladder 510 to deform the trachea fixedly connected to the inside again, thereby changing the position of sputum once more. The breathing simulation mechanism 5 and the angle adjustment vibration mechanism 2 can be activated simultaneously to simulate the violent fluctuations in breathing accompanied by coughing when a patient coughs. Through the coordination of these mechanisms, different sputum expectoration exercises can be performed.
