And (3) making a training plan by the patient or the doctor according to the conditions of different patients, and setting the corresponding indicating device at the height corresponding to the 10-level depth grade mark if the 10-level training is performed.

And (2) application II: setting of a preset height for a respiratory trainer in which a first resistance adjustment device 7, a second resistance adjustment device 8 and a third resistance adjustment device 9 are provided

The setting modes of the preset expiration height and the preset inspiration height are the same, and the preset expiration height is taken as an example for explanation:

the height, age and sex of the user are input through the interactive apparatus 10, and the controller 12 predicts the maximum vital capacity of the user, at which time the maximum vital capacity corresponds to the highest level of the depth class of exhalation, and the depth class of exhalation is at most N-level, i.e. the nth depth class of exhalation corresponds to the maximum vital capacity.

The represented lung capacity of the nth level of depth of expiration is different for different patients, taking the maximum lung capacity as Xml as an example, at this time, the nth level of depth of expiration is required to correspond to the lung capacity Xml by adjusting the first resistance adjusting device 7, the second resistance adjusting device 8 and the third resistance adjusting device 9, correspondingly, the 1 st level of depth of expiration is corresponding to the lung capacity X/Nml, the 2 nd level of depth of expiration is corresponding to the lung capacity 2X/Nml, the M th level of depth of expiration is corresponding to the lung capacity M X/Nml, and N > M > 2.

For the same patient, after the first resistance adjustment device 7, the second resistance adjustment device 8 and the third resistance adjustment device 9 are set, the subsequent adjustment is not performed. The doctor sets the expiratory depth training level for the patient according to the vital capacity represented by each expiratory depth level after setting.

Because the volume of the breathing chamber and the breathing chamber of the breathing training device is limited, the minimum vital capacity and the maximum vital capacity corresponding to the breathing training device are constant (such as the minimum vital capacity is 500ml and the maximum vital capacity is 5000 ml) under the condition that the resistance adjustment is not considered, the training with the maximum vital capacity being larger (such as 8000 ml) or the maximum vital capacity being smaller (such as 300 ml) cannot be satisfied, and the range of the breathing training can be enlarged by means of the resistance adjustment.

Specifically, the initial opening degrees of the air flow openings of the first resistance adjusting device 7, the second resistance adjusting device 8 and the third resistance adjusting device 9 are an intermediate value, for example, when the maximum opening degree and the minimum opening degree of the air flow openings are A and B respectively, A is greater than the initial opening degree of the air flow openings is greater than B, so that training with smaller maximum lung capacity can be realized by increasing the opening degrees and reducing the respiratory resistance; and the training with larger maximum vital capacity is realized by reducing the opening degree and increasing the respiratory resistance.

Specifically, the first resistance adjustment device 7, the second resistance adjustment device 8, and the third resistance adjustment device 9 are provided in the same manner as the correspondence relationship between the air flow ports and the lung capacities represented by the nth-stage exhalation depth scale, and the first resistance adjustment device 7 is described as an example:

When the first resistance adjustment device 7 adopts the manual adjustment mode, the correspondence between the plurality of first gas flow ports 701 and the lung capacity represented by the nth stage of exhalation depth level may be obtained by calibration or the like, for example, when the first gas flow ports 17 are adjusted to be aligned with the opening 18, the lung capacity represented by the nth stage of exhalation depth level is 8000ml, when the second gas flow ports 17 are aligned with the opening 18, the lung capacity represented by the nth stage of exhalation depth level is 5000ml, and when the nth gas flow ports 17 are aligned with the opening 18, the lung capacity represented by the nth stage of exhalation depth level is 300ml. The user may approximate the maximum lung capacity predicted by the controller 12 and select the most appropriate vent 17 to align with the aperture 18.

When the first resistance adjustment means 7 adopts an electric adjustment method (electromagnetic valve), the correspondence between the opening of the electromagnetic valve and the lung capacity represented by the nth stage exhalation depth level can be obtained by means of calibration or the like, and set in the controller 12. After the maximum lung capacity is predicted, the controller 12 automatically adjusts the opening of the solenoid valve.
