As shown in Figures 1 to 3, the breathing training device 1000 is a mouthpiece (10) in contact with the mouth of the trainee in order to breathe into the breathing training device (exhalation) or to breathe in (inhalation), A power generation unit 50 that generates an induced current according to the flow of air according to the inhalation and exhalation and outputs it to the control unit, and a control unit 60 that receives the induced current value output from the power generation unit and determines the respiration state. can

The power generation unit 50 and the control unit 60 may be located inside the case in the case 40 , the upper tab 20 connected to the upper portion of the case, and the lower tab 70 connected to the lower portion of the case. A filter 30 may be positioned between the upper tab 20 and the power generation unit 50 to prevent foreign substances such as saliva from entering the power generation unit and the control unit during breathing training of the trainee, and the filter includes the case 40 and It may be supported by the upper tab 20 . The lower tab 70 may have an air hole 71 through which air may flow into or out of the case according to a breathing motion. The trainee may perform breathing training through inhalation and exhalation by contacting the mouth with the mouthpiece 10 while holding the case by hand.

The power generation unit 50 may include a generator 51 that generates an induced current according to the rotational motion of the propeller 52 connected to the rotating shaft. The propeller 52 may rotate in the forward or reverse direction according to the breathing movement of the trainee. The generator 51 is composed of a magnet (rotor) connected to the rotating shaft and a coil (stator) surrounding the magnet, and can output an induced current generated by the trainee's breathing to the control unit.

The breathing training apparatus 1000 may further include an oxygen saturation sensor unit 90 capable of measuring the oxygen saturation of the trainee during breathing training of the trainee. The oxygen saturation sensor unit 90 may be formed in a portion of the case where the index finger is located when the trainee grips the case. The oxygen saturation sensor unit 90 utilizes a property that hemoglobin bound to oxygen better absorbs infrared rays, and reduced hemoglobin not bound to oxygen better absorbs red. The oxygen saturation sensor unit 90 includes a light emitting unit composed of two LEDs emitting infrared and red light, a photodiode for receiving light passing through the light emitting unit and a finger, and a control unit 60 for measuring values sensed by the light receiving unit It may include an output unit for outputting the . The oxygen saturation sensor unit 90 may be of a reflective type in which the light emitting unit and the light receiving unit are located on one surface of the case and irradiated with a finger by the light emitting unit and then the light reflected from the finger is measured, but a finger is placed between the light emitting unit and the light receiving unit. It can also be made of a transmissive type that is inserted and measured. The controller 60 may set a breathing training schedule according to the measured oxygen saturation value using the oxygen saturation value of the trainee input from the oxygen saturation sensor unit 90 . For general trainees, for example, it is difficult for a patient who is in a state with reduced lung function after surgery to determine how much breathing time and breathing schedule to exercise during initial breathing training. In other words, excessive breathing exercise in a state where the lung function is reduced is very dangerous for the patient because breathing difficulties occur. Accordingly, the present invention can provide a breathing training schedule according to the current trainer's lung function state by utilizing oxygen saturation information during respiration. The breathing training apparatus of the present invention has a structure in which an oxygen saturation sensor is attached to one side of the case, so that when the trainee naturally grabs the case by hand, the index finger contacts the oxygen saturation sensor surface. Therefore, the breathing training apparatus 1000 may use this oxygen saturation information to determine the oxygen saturation change amount according to the current patient's respiration during test respiration, and then determine the patient's lung function status, and according to the lung function status, By selecting the set breathing training schedule, it is possible to provide a customized breathing training schedule to the trainee. In addition, since oxygen saturation information for the trainee is continuously monitored during breathing training, the control unit 60 determines that it is hyperventilation when it exceeds the hyperventilation range compared to the breathing schedule set for the trainee, and sends it to the speaker or display. It is possible to deliver a warning to the trainee to stop the breathing exercise through the notification unit 63 made. In addition, the control unit 60 can determine whether the trainee is performing an effective breathing exercise by determining whether the appropriate oxygen saturation range according to the breathing intensity and breathing time according to the breathing schedule set by the trainee using the oxygen saturation value.

Respiratory training device 1000 is a converter 61 for converting the induced current output from the power generation unit 50 into direct current, a potentiometer 62 connected to the converter 61 to change the resistance according to the variable resistance control command of the controller ), an oxygen saturation sensor unit 90 for measuring the oxygen saturation of the trainee during breathing training, a notification unit 63 that transmits information to the trainee consisting of a speaker or a display unit, and preset breathing schedule information according to the trainee's breathing state. It may include a storage unit 64 that is stored and a control unit 60 for controlling the potentiometer 62 to adjust the breathing intensity during breathing exercise of the trainee.

The controller 60 may be made of a microcontroller (MPU), and may control the overall operation of the breathing training apparatus. The control unit 60 may receive an induced current value generated according to the breathing exercise and determine whether the trainee is currently performing an appropriate breathing exercise based on the breathing schedule information of the trainee. The respiration schedule information includes information such as various breathing patterns including breathing exercise time (including rest time), inspiratory and exhalation times, and respiration intensity levels to be performed by the trainee according to the results of the initial breathing test, and the oxygen saturation range during each respiration exercise. may include The respiration pattern may be set to various combinations of the number and time of exhalation and inspiration during one cycle, and the intensity of respiration during exhalation and inspiration. For example, the breathing pattern may be set as the first breathing intensity for 2 seconds and the second breathing intensity for 3 seconds in performing exhalation for 5 minutes of breathing exercise time, 5 minutes of rest time, and 5 seconds.

When the trainee reaches the breathing training target according to the breathing schedule information, the control unit 60 may control the potentiometer 62 to adjust the breathing intensity level during the next breathing training.

Figure 4 is a flowchart for explaining the operation of the breathing training apparatus according to an embodiment of the present invention, Figure 5 is a variable resistance in order to provide a breathing exercise according to the breathing intensity step by step to the trainee according to an embodiment of the present invention It is a schematic diagram for explaining the operation of the potentiometer to control.

Referring to FIG. 5 , the potentiometer 62 may include a plurality of switches 62a and a plurality of resistors 62b therein. The control unit 60 outputs the variable resistance control command to the potentiometer and opens and closes the switch 62a according to the variable resistance control command, thereby changing the resistance through which the induced current input from the power generation unit passes, and the induced current value output to the control unit. can be changed Here, the magnitude of the induced current value output to the control unit may be understood as respiration intensity.

Since the opening and closing of each switch of the potentiometer 62 is controlled according to the variable resistance control command of the control unit 60, the control unit controls the number of variable resistances through which the induced current output from the power generation unit passes. can control The meaning of controlling the magnitude of this induced current can be understood as the meaning of controlling the breathing intensity. For example, if the variable resistance through which the induced current must pass is added under the control of the controller in a state where the value of the induced current output without the variable resistance is X1 when the trainee is exercising at the first breathing intensity, the trainee can use the same The induced current value X2 output when exercising at the first breathing intensity is smaller than the induced current value X1. As the induced current output through the variable resistance becomes smaller according to Ohm's law, the trainee has a greater breathing intensity in the state with (added) variable resistance than that in the state without (not added) variable resistance. It can be understood that breathing exercises must be performed.

The control unit 60 outputs a variable resistance control command to short-circuit the switch S1 and the switch Sn to the potentiometer in order to receive the breathing state information of the first trainee. Based on the test induced current value output from the potentiometer and oxygen saturation information output from the oxygen saturation sensor, the control unit may set a breathing training schedule according to the current trainer's lung function status from the breathing training schedule information preset in the storage unit (S41) ). The test induced current value may be understood as an induced current generated from the power generation unit because it does not pass through the variable resistance of the potentiometer.

Next, in order to perform a breathing exercise with the trainee's target breathing intensity (the induced current value is preset to LEVEL 1) according to the preset breathing training schedule, the control unit 60 controls the variable resistance to short S2 and the switch Sn. By outputting a command to the potentiometer, it is possible to control the induced current to pass through the variable resistor R1 (S42). Here, since variable resistance is added, the trainee can reach the target breathing strength only by performing a breathing exercise harder than the breathing strength during the first test breathing. Here, although it has been described that the variable resistance control command is a short circuit between S2 and Sn, the variable resistance control command of the control unit may be made according to a breathing pattern according to a preset breathing exercise schedule of the trainee. For example, when the breathing pattern is set as the first breathing intensity for 2 seconds and the second breathing intensity for 3 seconds during exhalation for 5 minutes of breathing exercise time, 5 minutes of rest time, and 5 seconds (here, 2 respiration intensity is greater than the first respiration intensity), the control unit short-circuits switches S2 and Sn for 2 seconds to control to include the variable resistor R1, then short-circuits the switches S3 and Sn for 3 seconds to include the variable resistor R1 And by controlling to include R2 can provide a breathing exercise environment for the trainee to breathe harder gradually. That is, in order to provide an environment in which the trainee is trained to breathe according to the target breathing intensity according to the preset breathing exercise schedule, the control unit controls to increase or decrease the number of variable resistances through which the induced current passes. while performing effective breathing exercises.

If the oxygen saturation input according to the trainee's current breathing exercise is out of the oxygen saturation range of the preset training schedule (S43), the control unit 60 may control to immediately notify the trainee through sound or the display unit of a training stop message. (S46).

When the control unit 60 has an oxygen saturation value output from the oxygen saturation sensor unit within a preset oxygen saturation range (S43), and the induced current value is greater than the trainee's target respiration intensity according to a preset breathing training schedule, training It can be determined that the self-target breathing training has been achieved (S44). When the target breathing training is achieved, the control unit 60 stores the breathing exercise result in the storage unit, and can control to notify the breathing exercise result message to the trainer through the speaker or the display unit through the notification unit (S46).
