Description

[Detailed description of the invention] This invention relates to a notification means for notifying the wearing state of the detection means of an abdominal breathing exerciser.

The number of asthma patients is increasing due to the influence of air pollution in recent years, and when an asthma attack occurs, it becomes impossible for asthma patients to take in a sufficient amount of oxygen into their lungs using conventional breathing methods. Therefore, in the event of an attack, doctors instruct patients to switch to abdominal breathing to ensure that the necessary amount of oxygen is taken into the body. Correct abdominal breathing involves continuing to breathe by moving only the abdomen without moving the chest, but even if a seizure occurs, it may not be possible to do this properly.
It is said that you have to train more regularly every day than usual. An abdominal breathing training device is a device that checks whether you are performing abdominal breathing correctly during this training, but during this training, if you do not attach the detection means of the training device to your body correctly, you will not receive an appropriate signal. Therefore, abdominal breathing training cannot be performed properly.

Therefore, this invention aims to provide an abdominal breathing exerciser with a notification means for instructing the correct attachment of the detection means.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, 1 is a human body, and 2 is a sensor part, which is one of the detection means wrapped around the chest, and a transducer part which converts changes in the circumference of the chest due to breathing into changes in electrical signals. 3 is a sensor section that is similarly wrapped around the abdomen and has a function of detecting changes in the circumference of the abdomen due to breathing. Reference numeral 4 denotes a display device which processes the signals from the sensor sections 2 and 3 and displays whether or not abdominal breathing is being performed correctly. 5 is a tube-shaped elastic material in which an electrolytic solution 8 is sealed, and both ends of which are sealed with end caps 6 in which electrodes 7 are embedded. 9 is a lead part for taking out the resistance value of this electrolytic solution 8; 10 is a band part for wrapping the sensor parts 2 and 3 around the body;
1 is the buckle part. Further, 12, 13, and 14 are resistors, 15 is a variable resistor corresponding to the sensor sections 2 and 3, 16 is a comparator, and 17 is an LED that emits light based on the output from the comparator.

The operation will be explained in the above configuration.

When the elastic material 5 stretches, the electrolytic solution 8 inside is stretched thin and long, so the resistance 15 of the electrolytic solution 8 portion increases, and conversely, when the elastic material 5 contracts, the resistance 15 decreases. In this way, changes in body circumference can be replaced with electrical resistance. However, in this case, if the sensor parts 2 and 3 are wound too loosely, the sensor parts 2 and 3 will not correctly detect the area where the circumference of the human body 1 shrinks, and if the sensor parts 2 and 3 are wound too tightly, the sensor will be pre-biased in elongation. Therefore, in order to correctly detect the area where the circumference of the human body 1 increases, the sensor unit 2,
The detection range L of No. 3 must be widened, which increases the cost of the sensor. In a case like this embodiment, the sensor parts 2 and 3 wrapped around the human body 1 should ideally expand and contract around the midpoint l _p of the detection range L of the sensor characteristics as shown in FIG. However, it is unclear which state of the human body should be selected when setting the sensor parts 2 and 3 in the middle of the detection range L, which is actually quite difficult. It is. Therefore, in this embodiment, the detection range L of the sensor units 2 and 3 when the human body 1 exhales during normal breathing.
Comparator 16 turns ON at the set point l _d in the lower region of
Set the values of resistors 12, 13, and 14 so that
Since the output of the comparator 16 is connected to cause the LED 17 to emit light, the sensor unit 2,
When putting on item 3, hold it while exhaling.
If the bands 10 of the sensor sections 2 and 3 are fixed so that the LED 17 emits light, the detection range L of the sensor sections 2 and 3 can be used effectively. It goes without saying that the same effect as described above can also be expected by using a buzzer or the like instead of the LED 17 for notification.

Regarding the detection and display of abdominal breathing after the sensor parts 2 and 3 are correctly attached, a circuit may be provided to display changes in each part in a bar graph or to display a lamp when correct abdominal breathing is being performed. , which is unrelated to the gist of this invention and is a circuit that can be easily constructed, is omitted here.
In addition, in the above explanation, it was explained that the proper installation of the sensor parts 2 and 3 is notified by emitting light when you breathe out, but conversely, when you breathe in, the detection range of the sensor parts 2 and 3 is indicated by the LED 17. Light may be emitted at the l _u point on the L upper limit side. Of course, in this case, the + and - inputs to the comparator 16 may be connected in reverse.

Therefore, according to this invention, the detection means for detecting changes in the circumference of the chest and abdomen can be installed correctly and easily so that the change in circumference falls within the detection range, and the detection range can be minimized to the necessary minimum. It is effective in that it can be done.
