Description

Technical Field

[0001] This utility model relates to the field of respiratory training technology, and in particular to a respiratory resistance trainer adapted to a ventilator. Background Technology

[0002] In the medical field, patients who have difficulty weaning from ventilators often experience respiratory muscle disuse atrophy due to prolonged mechanical ventilation, making it difficult for them to leave the bedside. This further reduces their physical endurance and exacerbates their dependence on the ventilator. Numerous studies have shown that respiratory function training can enhance diaphragmatic mobility and thickness fraction, thereby increasing maximum inspiratory and expiratory pressures and improving respiratory muscle strength, especially through respiratory resistance training.

[0003] Currently, whether it's patients with difficulty weaning from endotracheal intubation or tracheostomy, respiratory muscle function training requires them to be able to temporarily wean off the ventilator and use a respiratory trainer connected through endotracheal intubation or tracheostomy. However, this procedure carries certain risks. First, the patient has difficulty weaning, is highly dependent on the ventilator, and has poor respiratory function; temporarily weaning off the ventilator means losing some respiratory support. Second, respiratory function training increases the load on the respiratory muscles, which can easily exacerbate respiratory failure and, in patients with poor baseline respiratory function, may even induce sleep apnea. Utility Model Content

[0004] Therefore, it is necessary to provide a highly practical respiratory resistance trainer that can ensure respiratory support for patients, avoid inducing respiratory failure, and be compatible with ventilators, addressing the problems that exist when existing patients are temporarily weaned off ventilators.

[0005] A respiratory resistance trainer adapted to a ventilator includes: a trainer body having an inner cavity, a resistance adjustment mechanism and an airflow monitoring mechanism mounted on the trainer body; one end of the trainer body has a first interface communicating with the inner cavity, and the other end of the trainer body has a second interface communicating with the inner cavity; the resistance adjustment mechanism includes two threaded rods connected to the trainer body, a spring sleeved on the threaded rods and abutting against the trainer body, a resistance block whose side is respectively sleeved on one of the threaded rods and abutting against the top of the spring, and a nut threadedly connected to the threaded rods and abutting against the top of the resistance block; the bottom end of the resistance block extends at least partially into the inner cavity.

[0006] The aforementioned respiratory resistance trainer, compatible with ventilators, can be connected to either the ventilator tubing or the endotracheal intubation port or tracheostomy opening via its first and second interfaces. When connected to the ventilator tubing, it allows for maximum respiratory resistance training while ensuring the patient's respiratory support, minimizing the risk of worsening respiratory failure and suffocation. When connected to the endotracheal intubation port or tracheostomy opening, the resistance adjustment and airflow monitoring mechanisms allow for adjustment of the training resistance. Connecting to the inspiratory tubing trains the patient's inspiratory function, while connecting to the expiratory tubing trains their expiratory function, providing continuous respiratory support and preventing the induction of respiratory failure—making it highly practical.

[0024] Please refer to Figures 1 to 5This is a schematic diagram of a respiratory resistance trainer 100 adapted to a ventilator according to the present invention. The respiratory resistance trainer 100 includes: a trainer body 20 having an inner cavity 21, a resistance adjustment mechanism 30 and an airflow monitoring mechanism 40 installed on the trainer body 20, wherein the airflow monitoring mechanism 40 can monitor the airflow in the inner cavity 21 in real time. One end of the trainer body 20 is provided with a first interface 22 communicating with the inner cavity 21, and the other end of the trainer body 20 is provided with a second interface 23 communicating with the inner cavity 21. The resistance adjustment mechanism 30 includes two threaded rods 31 connected to the trainer body 20, a spring 32 sleeved on the threaded rods 31 and abutting against the trainer body 20, a resistance block 33 whose side is respectively sleeved on one of the threaded rods 31 and abutting against the top of the spring 32, and a nut 34 threadedly connected to the threaded rods 31 and abutting against the top of the resistance block 33. The bottom end of the resistance block 33 extends at least partially into the inner cavity 21.

[0025] Furthermore, the training device body 20 has first protruding wing plates 24 on both sides, and the resistance block 33 has second protruding wing plates 35 on both sides. The two ends of the spring 32 abut against the first protruding wing plates 24 and the second protruding wing plates 35 respectively, and the nut 34 abuts against the top of the second protruding wing plate 35. The second protruding wing plate 35 and the first protruding wing plate 24 are arranged vertically opposite each other and are both rectangular block structures.

[0026] Furthermore, the main body 20 of the trainer is provided with a guide portion 25 communicating with the inner cavity 21. The bottom end of the resistance block 33 extends at least partially into the guide portion 25. During use, the resistance block 33 can move up and down elastically in a piston pattern within the guide portion 25 under the action of the spring 32. In this embodiment, the cross-section of the guide portion 25 and the resistance block 33 is rectangular. Furthermore, a sealing ring 26 is installed on the inner wall of the guide portion 25. The sealing ring 26 abuts against the outer wall of the resistance block 33, ensuring a tight seal between the resistance block 33 and the guide portion 25, preventing air leakage. In this embodiment, the sealing ring 26 is a rubber ring.

[0027] Furthermore, the first interface 22 and the second interface 23 are arranged opposite to each other, and the first interface 22 and the second interface 23 are circular tube openings with the same axis. In this embodiment, the shape of the trainer body 20 is a cuboid, and the arrangement of the coaxial first interface 22 and second interface 23 can effectively ensure the smooth flow of air.

[0028] Furthermore, the airflow monitoring mechanism 40 includes a microcontroller 41 and a protective cover 42 mounted on the trainer body 20, and an airflow sensor 43 mounted on the microcontroller 41 and partially located within the inner cavity 21. The microcontroller 41 is located within the protective cover 42. The airflow sensor 43 can monitor the airflow within the inner cavity 21 in real time. Further, the airflow monitoring mechanism 40 also includes a Bluetooth module 44 mounted on the microcontroller 41. The Bluetooth module 44 can establish a data transmission link with an external display device, thereby displaying airflow curves and values ​​in real time, visualizing the impact of assisted breathing on the patient's spontaneous breathing, and facilitating resistance adjustment. In this embodiment, a cable inlet (not shown) is provided on the side of the protective cover 42 to facilitate connecting the power cord to the microcontroller 41. In this embodiment, the resistance adjustment mechanism 30, in conjunction with the airflow sensor 43, dynamically adjusts the breathing resistance of the breathing trainer. Even at maximum breathing resistance, it does not block the breathing support of the ventilator, and the resistance block 33 is fixed by screws on both sides, making it difficult to loosen. It should be noted that the microcontroller 41 is an existing technology product, mainly composed of a control circuit board and various electronic components mounted on the control circuit board, which will not be described in detail here. In this embodiment, the first interface 22 is located on the side closer to the resistance block 33, and the airflow sensor 43 is located on the side of the airflow sensor 43.

[0029] The working principle of the respiratory resistance trainer 100 applicable to ventilators is as follows: When connected to the breathing circuit, it can be connected to either the inspiratory or expiratory circuit. For example, when connected to the inspiratory side: the inspiratory airflow first passes through the end near the resistance block 33 and flows out from the end of the airflow sensor 43. The resistance block 33 is initially adjusted to its highest position. When the patient inhales naturally, the airflow sensor 43 senses the airflow and plots an airflow change curve. Then, the operator applies respiratory resistance by lightly pressing the resistance depth. When the operator releases the pressure, the spring 32 causes the module to return to its original position. For the first training session, it is recommended to press the resistance block 33 to a depth of 20%. By observing the patient's facial expressions, vital signs, simple gestures, and the airflow change curve, the depth of the resistance block 33 is gradually adjusted to adjust the respiratory resistance. Once a suitable respiratory resistance is achieved for the patient, the depth of the resistance block 33 is fixed by tightening the nuts 34 on both sides of the resistance block 33. After the respiratory training is complete, the nuts 34 on both sides of the resistance block 33 are loosened, and the spring 32 causes the resistance block 33 to automatically return to its original position.

[0030] The aforementioned respiratory resistance trainer 100, compatible with ventilators, can be connected to ventilator tubing via the first interface 22 and the second interface 23, or to an endotracheal intubation port or tracheostomy opening. When connected to ventilator tubing, it allows for maximum respiratory resistance training while ensuring the patient's respiratory support, minimizing the risk of worsening respiratory failure and suffocation. When connected to an endotracheal intubation port or tracheostomy opening, the resistance adjustment mechanism and airflow monitoring mechanism allow for adjustment of the training respiratory resistance. Connecting to the inspiratory end of the tubing trains the patient's inspiratory function, while connecting to the expiratory end trains expiratory function, providing continuous respiratory support and preventing the induction of respiratory failure, making it highly practical.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
