Description

Technical Field

[0001] This utility model provides a respiratory training device for cardiopulmonary rehabilitation, belonging to the technical field of respiratory training equipment. Background Technology

[0002] Breathing training is a core component of cardiopulmonary rehabilitation. Through targeted adjustments to breathing patterns, breathing training promotes gas exchange in the lungs, strengthens respiratory muscles, alleviates symptoms of dyspnea, and improves patients' quality of life and exercise endurance.

[0003] Existing respiratory trainers have a simple structure. During expiratory training, the patient blows air in through the inlet, and the air eventually flows out through the outlet. However, different patients have varying levels of cardiopulmonary function and rehabilitation needs, requiring flexible adjustments to the training intensity to suit each patient's specific situation. Furthermore, adjusting the training intensity during expiratory training is inconvenient with existing devices. Monitoring the duration of exhalation is also crucial. An expiratory timing device helps patients and therapists accurately record the time of each exhalation, thereby assessing training effectiveness and progress. However, timing exhalations typically requires manual timing by the patient, which is inconvenient and has low accuracy. Utility Model Content

[0004] The technical problem this invention aims to solve is that when using a breathing trainer for expiratory training, it is inconvenient to adjust the intensity of the expiratory training and also inconvenient to monitor and time the duration of the expiratory process.

[0005] To solve the above problems, the proposed technical solution is as follows: a respiratory training device for cardiopulmonary rehabilitation, comprising an air inlet box and a training cylinder, wherein the training cylinder is fixedly connected to the air inlet box, and the air inlet box has a connection hole communicating with the training cylinder; an air inlet hole is provided on one side of the air inlet box, and an air outlet hole is provided at the upper end of the training cylinder; further comprising:

[0006] The air intake box includes an elastic sliding component and a pressure sensor.

The lightweight slider is slidably disposed inside the air intake box, and the sliding rod is fixedly connected to the lightweight slider. A guide groove is provided on the inner wall of the air intake box, and the sliding rod is slidably inserted into the guide groove. The pressure sensor has a ring structure, and the spring is located between the pressure sensor and the lightweight slider, and the spring is sleeved on the sliding rod.

[0009] As an improvement, a limit block is fixedly installed inside the air intake box, and the limit block is located on the side of the lightweight slider; the spring is reserved with a compression amount.

[0010] As an improvement, an air inlet is connected to an air nozzle, and a display is fixedly connected to the side wall of the air inlet box above the air nozzle, and the display is connected to the controller circuit.

[0011] As an improvement, the rotation adjustment assembly includes a rotating block and an operating rod. The rotating block is rotatably disposed in the groove, and an adjustment hole is opened on the rotating block.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] according to Figure 1-5 As shown: This utility model provides a respiratory training device for cardiopulmonary rehabilitation: it includes an air intake box 1 and a training cylinder 2. The training cylinder 2 is fixedly connected to the air intake box 1, and the air intake box 1 has a connection hole 8 communicating with the training cylinder 2; an air inlet 4 is provided on one side of the air intake box 1, and an air outlet 7 is provided at the upper end of the training cylinder 2; both the air intake box 1 and the training cylinder 2 are made of transparent material for easy viewing by the patient; it also includes:

[0025] The elastic sliding component and the pressure sensor 13 are provided. The elastic sliding component is slidably disposed in the air intake box 1, and the pressure sensor 13 is fixedly disposed on the inner wall of the air intake box 1, and the pressure sensor 13 is located at the position corresponding to the elastic sliding component. The outer wall of the air intake box 1 is provided with a controller 3 that is electrically connected to the pressure sensor 13, and the controller 3 is provided with a timing module.

[0026] The groove 15 is located inside the training cylinder 2 and corresponds to the air outlet 7. The rotation adjustment component is rotatably located inside the groove 15 and has several adjustment holes 17 corresponding to the air outlet 7.

[0027] like Figure 3As shown, the elastic sliding assembly includes a lightweight slider 9, a sliding rod 12, and a spring 10. The lightweight slider 9 is slidably disposed within the air intake box 1, and the sliding rod 12 is fixedly connected to the lightweight slider 9. A guide groove 11 is provided on the inner wall of the air intake box 1, and the sliding rod 12 is slidably inserted into the guide groove 11. The pressure sensor 13 has a ring structure, and the spring 10 is located between the pressure sensor 13 and the lightweight slider 9, and the spring 10 is sleeved on the sliding rod 12. When gas enters the air intake box 1 through the air intake port 4, it can generate a thrust on the lightweight slider 9, thereby compressing the spring 10 and changing the monitoring value of the pressure sensor 13. The timing module is used to time the change in the pressure sensor 13 value, thereby accurately monitoring the exhalation duration without requiring the patient to manually time it.

[0028] A limiting block 14 is fixedly installed inside the air intake box 1, and the limiting block 14 is located on one side of the lightweight slider 9, which can limit the lightweight slider 9; the spring 10 has a reserved compression amount, which can ensure that after exhalation, the lightweight slider 9 can always be in the original position under the action of the spring 10's rebound force.

[0029] like Figure 2 As shown, an air inlet 4 is connected to an air nozzle 5. Above the air nozzle 5 is a display 6 fixedly connected to the side wall of the air inlet box 1. The display 6 is connected to the controller 3 by circuit. The display 6 can display the exhalation time, which is convenient for the patient to check in time after the exhalation training.

[0030] like Figure 4 As shown, the rotation adjustment assembly includes a rotating block 16 and an operating rod 18. The rotating block 16 is rotatably disposed within the groove 15, and an adjustment hole 17 is formed on the rotating block 16. The operating rod 18 is rotatably connected to the training cylinder 2 and is fixedly connected to the rotating block 16. Four adjustment holes 17 are provided, each of different sizes, and are evenly distributed circumferentially on the rotating block 16. The operating rod 18 can drive the rotating block 16 to rotate, aligning the different sized adjustment holes 17 with the air outlet 7, thereby changing the size of the air outlet 7 and adjusting the exhalation training intensity. Static friction exists between the rotating block 16 and the groove 15, ensuring that after adjustment, the rotating block 16 remains stably within the groove 15 due to static friction.

[0031] The principle of this utility model

[0032] like Figure 1 , 2 As shown, during expiratory training using this application, the patient inhales from the outside and blows air into the air inlet box 1 through the mouthpiece 5 and air inlet 4. The air enters the training cylinder 2 through the connecting hole 8 and finally flows out from the air outlet 7. Figure 3As shown, during exhalation training, after the gas enters the air intake box 1, it generates a pushing force on the lightweight slider 9, causing the lightweight slider 9 to drive the sliding rod 12 to slide a short distance in the guide groove 11. The lightweight slider 9 compresses the spring 10, and the pressure value sensed by the pressure sensor 13 changes. At the same time, the timing module in the controller 3 can start timing. When exhalation is completed, under the action of the spring 10's rebound force, the lightweight slider 9 returns to its original position. At this time, the pressure value sensed by the pressure sensor 13 returns to the initial state, the timing module ends timing, and the final timing result is displayed on the display 6 for the patient to check.

[0033] like Figure 4 , 5 As shown, the training intensity can be adjusted before exhalation training; turning the operating lever 18 causes the rotating block 16 to rotate, aligning the adjustment holes 17 of different sizes with the air outlet 7; when it is necessary to increase the training intensity, the smaller adjustment hole 17 is selected to be aligned with the air outlet 7, at which time the resistance to gas flow increases, thus increasing the training intensity; when it is necessary to decrease the training intensity, the larger adjustment hole 17 is selected to be aligned with the air outlet 7, at which time the resistance to gas flow decreases, thus decreasing the training intensity.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
