[0002] Respiratory function is one of the most basic physiological functions. Respiratory dysfunction is common in neurological diseases, such as severe stroke, brain trauma, neuromuscular junction disease, spinal cord injury, chronic respiratory diseases and the elderly. Respiratory dysfunction not only damages the functions of various important organs, but also seriously affects the quality of life and rehabilitation effect of patients. Therefore, respiratory rehabilitation is an important branch of modern rehabilitation and is crucial to the rehabilitation of patients. In addition, respiratory training is also used in the field of sports health. Respiratory training can effectively increase human lung capacity, improve lung function, enhance physical fitness, and improve athletes' performance.

[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0057] Please refer to Figures 1 to 6 The breathing trainer includes a housing 1, a breathing tube 2, a sensing module 23 and a signal processor 7.

[0058] The bottom of the housing 1 has a tube groove 11, and the breathing tube 2 is snap-fitted and installed in the tube groove 11. The breathing tube 2 is a hard tube, and the end of the breathing tube 2 corresponding to the front end of the housing 1 is used for breathing. Specifically, a hose can be connected to this end, and breathing or inhaling into the breathing tube 2 through the hose is performed for breathing training. The end of the breathing tube 2 corresponding to the rear end of the housing 1 is connected to the environment, and a slot cover 3 is snap-fitted and installed at the mouth of the tube groove 11. The breathing tube 2 can be removed from the tube groove 11 by removing the slot cover 3. In addition, the breathing tube 2 can also be designed so that the front end protrudes from the front end of the housing 1, and breathing or inhaling into the breathing tube 2 directly through the front end of the breathing tube 2 is performed for breathing training.

[0059] A chamber 13 is formed between the upper shell and the lower shell of the housing 1, and a signal processor 7 is installed in the chamber 13. The signal processor 7 is connected to the sensing module 23, receives the electrical signal output by the sensing module 23, and generates respiratory data. The signal processor 7 includes a circuit substrate 232, and a processing chip installed on the circuit substrate 232. The processing chip can be a single chip microcomputer, a CPU (Central Processing Unit), an MCU (Microcontroller Unit), a DSP (digital signal processing), etc.

[0060] The sensing module 23 is configured to sense data of the gas in the breathing tube 2 .

[0061] In this embodiment, the sensing module 23 is installed on the breathing tube 2 and is connected to the signal processor 7 through an electrical connector. The electrical connector specifically adopts a contact electrode 12. The contact electrode 12 is preferably an elastic probe. One end of the contact electrode 12 is electrically connected to the signal processor 7, and the other end of the contact electrode 12 extends into the tube groove 11. When the breathing tube 2 is fixed in the tube groove 11, the electrode on the sensing module 23 is correspondingly abutted and matched with the contact electrode 12 to achieve electrical connection.

[0062] The above-mentioned configuration of the sensing module 23 on the breathing tube 2 allows the sensing module 23 to be replaced after the breathing tube 2 is replaced, that is, during breathing training, all parts through which the airflow flows are replaced, thereby better preventing cross infection through the breathing trainer.

[0063] The sensing module 23 of this embodiment includes a substrate 232 and a sensor 231 mounted on the substrate 232, wherein the sensor 231 includes a pressure sensor and a gas flow sensor. The pressure sensor senses the air pressure data in the breathing tube 2. The gas flow sensor senses the gas flow in the breathing tube 2. The signal processor 7 processes the air pressure data and the gas flow data to obtain relevant breathing data in real time, wherein the breathing data includes one or more of the following: expiratory pressure, inspiratory pressure, pressure difference between exhalation and inhalation, exhalation time, inhalation time, number of trainings, and volume of gas exhaled and inhaled by the trainee.

[0064] The sensing module 23 is preferably mounted on the breathing tube 2 by snap-fitting, so that after the sensing module 23 is removed from the breathing tube 2, the breathing tube 2 can be conveniently disinfected for reuse without worrying about damage to the sensor 231 during the disinfection process.

[0065] The breathing trainer further comprises a display screen 4, which is mounted on the top of the housing 1. The display screen 4 is preferably an LCD. The display screen 4 is connected to the signal processor 7 and is used to display various data.

[0066] The breathing training device also includes a data storage device, which is connected to the signal processor 7. The data of each breathing training can be stored, wherein the breathing training data may include the level data of the breathing tube 2 in addition to the above-mentioned breathing data.

[0067] The breathing trainer also includes a wireless communication module 8, which is connected to the signal processor 7. Through the wireless communication module 8, the breathing data is sent to the associated device on the one hand, and instructions can be received from the associated device on the other hand to achieve remote parameter setting or remote control of the breathing trainer. The associated device can be a management server, a smart phone, etc.

[0068] Figure 5 A configuration of the breathing tube 2 is shown in FIG. Figure 5The present breathing tube 2 comprises: a tube body 21; a receiving groove 22 of a sensing module 23 disposed on the tube body 21; an axial limiting portion 26 for limiting the movement of the tube body 21 along its axial direction; a rotation-blocking portion 25 for limiting the rotation of the tube body 21 around its axis; and a buckle 24 for engaging with the buckle on the tube groove 11 to keep the tube body 21 in the tube groove 11. The axial limiting portion 26 is specifically a convex strip protruding outward from the outer circumference of the tube body 21, and the rotation-blocking portion 25 is specifically a plane at the bottom of the convex strip, the side of which abuts against the protruding portion in the tube groove 11 to prevent the breathing tube 2 from moving along its axial direction, and the plane at the bottom of the convex strip abuts against the groove cover 3 to prevent the breathing tube 2 from rotating around its axis. The breathing tube 2 can not only realize the snap-fit ​​combination between the breathing tube 2 and the tube groove 11, and realize the snap-fit ​​combination between the sensing module 23 and the breathing tube 2, but also prevent the breathing tube 2 from axial displacement and rotational displacement after installation, thereby ensuring the reliability of the electrical connection of the sensing module 23, and further ensuring the reliability of the operation of the entire machine.

[0069] As a preferred embodiment, an air filter is further provided in the tube body 21. When inhaling, the ambient gas passes through the air filter and then enters the trainee's mouth, which can prevent dust, bacteria, etc. in the air from entering the mouth with the air.

[0070] As an embodiment, the breathing tube 2 is a variable diameter tube. A variable diameter tube is a tube with different inner diameters. Here, the ratio of the maximum inner diameter to the minimum inner diameter is called the variable diameter ratio. The trainee can replace the breathing tube 2 with different variable diameter ratios according to the progress of training to achieve a better training purpose.

[0071] As another embodiment, the breathing tube 2 is a tube of equal diameter. An equal diameter tube means that the inner diameter of the same tube body is the same. The trainer can select breathing tubes 2 of different inner diameters according to the progress of training to achieve the purpose of breathing training.

[0072] In order to complete the training of each training stage with the same equal-diameter tube, an aperture adjustment mechanism 6 can be further provided to adjust the size of the aperture of the breathing tube 2 communicating with the environment.

[0073] Figure 7 and Figure 8 FIG. 6 shows a structure of an aperture adjustment mechanism 6. Figure 7 and Figure 8The aperture adjustment mechanism 6 includes: a turntable 61, having a plurality of through holes 611 with different apertures, wherein when in use, the turntable 61 is placed opposite to the end of the breathing tube 2, and the plurality of through holes 611 respectively pass through the end of the breathing tube 2 during a rotation around its support axis; a driving motor 62, wherein when in use, the driving motor 62 is installed on the housing of the breathing trainer, and the driving motor 62 is configured to drive the turntable 61 to rotate; and a controller, configured to control the driving motor 62, so that the turntable 61 is at a specified position, and when the turntable 61 is at the specified position, the specified through holes 611 on the turntable 61 are aligned with the breathing tube 2. Figure 8 In the figure, the turntable 61 has five through holes 611 with different apertures. The five through holes 611 are evenly distributed on the same circumference. When the turntable 61 rotates 72 degrees, one through hole 611 can be switched to align with the breathing tube 2.

[0074] A detection unit 612 is provided at the edge of the turntable 61 . The detection unit 612 cooperates with a position sensor to calibrate the initial position of the turntable 61 .

[0075] The controller may be a manual input unit, which may include but is not limited to a key, a touch switch, etc. The signal processor 7 receives the input of the manual input unit, and then controls the drive motor 62 to switch the position of the turntable 61. The controller may also be a program executable by the signal processor 7, which determines the required diameter of the breathing tube 2 according to the number of training times, and then controls the drive motor 62 to switch the turntable 61 to the corresponding position.

[0076] Fig. 9 Another structure of the aperture adjustment mechanism 6 is shown in FIG. The aperture adjustment mechanism 6 is a plurality of gas nozzles with different apertures, such as Fig. 9 As shown, when in use, select an air nozzle with a suitable aperture and fix it to the end of the breathing tube 2, which can be detached. In this embodiment, the air nozzle and the breathing tube 2 are specifically combined by plugging, and a sealing rubber ring is provided at the plugging part. In addition, the air nozzle and the breathing tube 2 can also be combined by threaded connection, clamping connection, etc. The trainee can replace the air nozzle with different apertures according to the progress of training to achieve a better training purpose.

[0077] As can be seen from the above, the breathing trainer is composed of a breathing tube 2 and a main unit, and the breathing tube 2 constitutes the entire air flow channel of the breathing trainer. On the one hand, the breathing tube 2 can be easily removed from the main unit for disinfection and cleaning. On the other hand, the breathing trainer can be used by different trainees by simply replacing the breathing tube, and cross-infection of respiratory diseases caused by different trainees using the same breathing trainer can be avoided.

[0078] The breathing trainer is particularly suitable for use at home and in the community. The trainee only needs to bring his own breathing tube and combine it with the public trainer host to carry out training, without having to purchase a dedicated breathing trainer, and cross infection of respiratory diseases will not occur.

[0079] The present invention is described in detail above through specific embodiments, and these detailed descriptions are only limited to helping those skilled in the art understand the content of the present invention, and cannot be understood as limiting the scope of protection of the present invention. Various modifications, equivalent transformations, etc. made by those skilled in the art to the above scheme under the concept of the present invention should be included in the scope of protection of the present invention.
