The sensor unit 110 and the body unit 120 may have coupling units 111 and 121 so as to be coupled to each other inside and outside with the mask body 41 therebetween. Therefore, the sensor unit 110 and the body portion 120 can be easily mounted and separated, there is an advantage that can be combined by replacing the sensor unit 110 in various specifications. In addition, the coupling portions 111 and 121 of the sensor unit 110 and the body portion 120 may have a configuration in which a screw line is formed to be screwed together, and in addition to the screw coupling method, the clip coupling method, or the hook coupling method. It may have a configuration. In addition, when the sensor unit 110 and the body unit 120 are coupled to each other, the terminals may have a configuration to enable electrical contact with each other by a connection method. And the sensor unit 110 and the body portion 120 has a structure that allows the passage of air between each other, the body portion 120, the outlet to allow the air discharged from the sensor unit 110 to go to the outside, that is, the atmosphere It can have The outlet may be provided with a net for preventing the inflow of foreign matter or dust.

As described above, by measuring the wearer's breath using the breathing apparatus 40 according to an embodiment of the present invention, the wearer's biometric information, that is, the amount of change in oxygen and carbon dioxide, the amount of change in pressure according to breathing, etc. By analyzing the data, it is possible to obtain data capable of precisely analyzing the state of health, that is, the living state. That is, as shown in Figures 4, 5 and 6, by analyzing the gas exchange between the alveoli and alveolar according to the wearer's breathing through the biometric information measured at regular intervals, and analyzes the breathing state of the wearer precisely, The analysis results can confirm the wearer's health. In other words, it is determined by analyzing whether the wearer is in normal breathing, poor breathing, or difficulty breathing or apnea through the change of the pattern according to the time between exhalation and exhalation, and the pressure change according to the discharge rate of the exhalation detected at the time of exhalation. can do. In normal breathing, it can be determined as a stable state, and during empty breathing, the body is in a moving state. In case of difficulty in breathing or apnea, it can be determined as oxygen deficiency.

In addition, through the pattern of exhalation and exhalation and the concentration change of oxygen and carbon dioxide, it is possible to determine whether it is breathing, hyperventilation, bulgal breathing, or excessive breathing. In the case of Western breathing can be determined as gas poisoning, the step leading to irregular breathing from excessive breathing, and excessive breathing, such as the situation immediately before the worker causes seizures or stop breathing can be determined as a very dangerous situation.

Here, as is commonly known, the tidal volume is 500 mL for adults, 2,500 to 3,500 mL for food preservation, 1,200 mL for food preservation, and 1,200 mL for residues. The normal range is 15 to 20 times / 1 min based on the minute volume. Apnea, poor breathing is more than 30 to 50 times / min, West breathing is less than 10 times / min, hyperventilation will increase the respiration frequency and depth.

As such, by analyzing the biometric information acquired through the respiratory state, it is possible to determine whether the borrower is in a normal state, in an active state, at rest, or in an oxygen deficient state.

In addition, as shown in Figure 5, by analyzing the relationship between the lung volume and carbon dioxide as a graph, it can be confirmed whether the normal respiratory state. That is, in order to show the increase and decrease curve of carbon dioxide, it should have a sensing cycle of at least 10 times / Sec (100ms), and based on this, the normal breathing will have 12 to 15 breathing cycles. Can be determined.

As shown in FIG. 6, when the amplification of the detected information, that is, the amount of change is minute, and accurate analysis is difficult, biometric information can be analyzed more accurately using differential analysis.
