Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an abdominal breathing exerciser, and particularly to a display method thereof. The number of asthma patients is increasing due to the effects of air pollution in recent years. When an asthmatic attack occurs, it becomes impossible for asthma patients to take in a sufficient amount of oxygen into their lungs using conventional breathing techniques. Therefore, during these attacks, doctors instruct patients to switch to abdominal breathing to bring in the necessary amount of oxygen into the body.

However, correct abdominal breathing cannot be achieved even if it is suddenly performed during an attack, so patients need to constantly practice proper abdominal breathing under the guidance of a doctor in order to be able to do proper abdominal breathing during normal times.

This invention was made in order to provide a device that can monitor whether or not abdominal breathing is being performed correctly without the guidance of a doctor. This was done to provide a display means that allows the user to see the results of their efforts at a glance. A detailed explanation will be given below with reference to the drawings.

FIG. 1 shows the state of use of an embodiment of the present invention, in which 1 is a human body, 2 is a sensor section attached to the chest, 2-A is a transducer for the displacement, and 2-B is a band section. be. 3 is a sensor section attached to the abdomen, 3-A is a displacement transducer, 3-B is a band section, and 2 and 3 have exactly the same configuration. Reference numeral 4 denotes a main body section that detects and displays signals from the sensor.

FIG. 2 is an enlarged view of the main part of this main body, and 5 is an output display section according to the sensor output, and in this embodiment, the front element 5-1- displays the quantized displacement for each abdomen and chest, respectively. A~5-1-F,5-2-A,5-
It is composed of 2-F. Reference numeral 6 indicates an input connection section from the sensor sections 2 and 3.

As can be seen from this figure, this invention is based on the sensor section 2.
The changes in circumference of the abdomen and thorax due to breathing detected in steps 3 and 3 are quantized by a predetermined amount of displacement in a circuit within the main body 4, and then the corresponding display elements are displayed according to the quantization value. It is characterized by being displayed in the form of a lit bar graph.

FIG. 3 shows an example of the configuration of the displacement transducer sections 2-A and 3-A constituting the sensor section, in which both ends of the tube-shaped elastic device 7 are connected to an end cap 11 in which an electrode 9 is embedded. It has a sealed structure in which an electrolytic solution 8 is sealed inside. 10 is a lead wire for taking out the resistance value of this electrolytic solution. Therefore, if the elastic body 7 expands in response to changes in the circumferential lengths of the abdomen and chest, the resistance value between the lead wires 10 will increase, and if it expands and contracts, the resistance value will decrease.
This means that the displacement signal can be replaced with a change in electrical resistance. Next, FIG. 4 shows an example of a circuit that quantizes and displays signals from the sensor section. In the same figure, 12 indicates a DC power supply, and 13 indicates a resistor that converts the partial pressure value between the abdominal sensor 3-A and the comparator 35-A.
~35-F is input as a signal to one input terminal. 1
5, 17, 21, 23 to 28 are resistors, which together with the variable tuner diode 19 are connected to the comparator 35.
Reference voltages for -A to 35-F are created respectively. 37 are respective display elements 5-1-A to 5-1-
This is a resistor for limiting the current of F. When a voltage corresponding to the resistance value of the sensor section 3-A is input to each comparator in the circuit having the above configuration, each comparator performs a magnitude comparison with its own unique reference voltage, and the signal input is determined to be the reference voltage. If it is smaller, the corresponding display element is lit. Therefore, when the sensor part changes its resistance in response to a change in circumference, this is input to the comparator as a voltage change, and the display is obtained in the form of a bar graph in synchronization with breathing, as shown in Figure 5. . The same circuit that performs exactly the same operation can be used for the chest side sensor section 2-A, so the explanation is omitted here, but it goes without saying that each component in Fig. 4 corresponds to each part on the abdominal side. be.

In general, correct abdominal breathing means continuing to breathe by moving only the circumference of the abdomen as much as possible without moving the chest. For asthmatic patients, especially children with asthma, practicing this breathing method is very simple and requires continuous practice, which can easily cause problems such as giving up halfway through.

Therefore, in order to avoid this monotony, it is important to make the display itself as clear as possible about the results of efforts made.

According to this invention, this display is converted into a bar graph,
This aspect can be improved by displaying the abdomen and chest in contrast. In the above embodiment, the quantization stages are shown as six stages A to F, but it is obvious that the same structure can be used regardless of the number of stages.
