1 is a front view of a MEMS sensor based self breathing training system according to the present invention.

MEMS sensor-based self-breathing training system 10 (hereinafter referred to as 'breathing training system') is a device for training breathing to have a constant cycle of the subject's breath to receive respiratory-linked radiotherapy. When the breathing training system 10 is worn on the chest and breathing, the relative change according to the breath is provided to the examinee as a graph, and the examinee self-recognizes and trains to form a regular cycle of breathing pattern.

The respiratory training system 10 has a permanent magnet 40 generating a magnetic field on one surface of the adjustable band 20 so that the breathing training system 10 can be worn on the chest of the examinee, and the sensor unit to face the permanent magnet 40 ( 30) is installed.

The material of the band 20 is made of an elastic belt that stretches and shrinks well and is easy to adjust the length, and the belt made of a material such as leather or nylon of a fixed length material has a length adjusting means for adjusting the length (mido H) may be provided together. However, the investigator wearing the band 20 should not have a feeling of rejection or discomfort in wearing, and may be made of any material as long as the length can be easily adjusted to fix the worn portion.

The permanent magnet 40 is positioned on one surface of the band 20 to maintain a strong magnetization state for a long time and generate a stable magnetic field without receiving electric energy from the outside. The permanent magnet 40 may be made of a material having a high residual magnetism and coercive force.

The other side of the band 20 is attached to the sensor unit 30 provided with the MEMS sensor 32 to face the permanent magnet 40 is to detect the magnetic field generated in the permanent magnet 40. The MEMS sensor 32 has a rectangular parallelepiped shape consisting of a width of 35 mm, a length of 60 mm, and a height of 15 mm, and may be slightly larger or smaller than this.

Each surface of the sensor unit 30 having a rectangular parallelepiped shape is positioned so that the MEMS sensor 32 faces the permanent magnet 40. Therefore, the MEMS sensor 32 located on each surface calculates the position change by calculating the magnetic field of the permanent magnet 40 detected from another axial direction as a vector value.

That is, the MEMS sensor 32 of the sensor unit 30 measures the position change through the magnetic force line density of the permanent magnet 40.

In the form of the sensor unit 30 will not necessarily be composed of a rectangular parallelepiped. However, if the polyhedron formed so as to utilize the MEMS sensor 32 most efficiently and economically, it may be made of polygons of various sizes.

2 shows a detailed view of a MEMS sensor-based self-breathing training system according to the present invention.

The sensor unit 30 and the permanent magnet 40 are located on the belt 20 to face each other, thereby enabling more accurate magnetic field measurement. The other surface of the sensor unit 30 and the permanent magnet 40 facing each other is further provided with an adhesive tape or velcro to be attached to the belt 20.

The sensor unit 30 and the permanent magnet 40 may be permanently fixed to the belt 20 according to the convenience of use or fabrication. In the case of making the detachable for hygienic use, various adhesive members may be used in addition to the adhesive tape or the Velcro. Will be available.

The breathing training system 10 is worn on the chest of the examinee, and the sensor unit 30 is worn toward the chest and the permanent magnet 40 is worn toward the back.

When the examinee wearing the respiratory training system 10 breathes for a predetermined time, the position change of the magnetic field while breathing by measuring the magnetic field of the permanent magnet 40 of the MEMS sensor 32 of the sensor unit 30 Will be shown.

In this case, the sensor unit 30 is connected to an image output device (not shown) such as a monitor by wireless or wired, so that the patient can show a graph in real time. In addition, the sensor unit 30 and the permanent magnet 40 will not necessarily be worn as described above, the wearing position may be changed at any time according to the convenience or measurement accuracy of the examinee.

On the other hand, by looking at the graph provided by the MEMS sensor 32 it is possible to set the maximum exhalation (lowest value: 0%) and the maximum inhalation (highest value: 100%) through this to train to have regular breathing.

If the investigator is out of the reference range of the set period or position value while breathing, the sensor unit 30 immediately informs the examinee, and the examinee who recognizes this is to breathe in a certain cycle through respiration training.

The sensor unit 30 is further provided with a vibrator (not shown) that immediately informs the examinee when the breathing cycle is out of the reference value. In addition to the vibrator may be provided with a bell to generate an alarm sound, any means of alarm may be any means that can give feedback to the examinee.

The subject receives feedback through the vibrator to control the breathing cycle, and if used repeatedly, the subject will have regular breathing.

Respiratory training system 10 can be trained at any time in the desired space irrespective of time and place, and when the power consumption of the MEMS sensor 32 is consumed according to long-term use, charging or replacing the battery continuously Could be used.

The respiratory training system does not necessarily secure the sensor and the permanent magnet to the chest of the examinee with a belt, but would be sufficient if it could be secured to prevent it from flowing down by using an adhesive member or other types of fixing members. In addition, the size of the permanent magnet may be large or small depending on the body size of the examinee, it may be measured by varying the number of permanent magnets.
