The support 23 is preferably made of a material such as hard synthetic resin, and performs a function of maintaining the shape of the wearing module 10 when the entire air pressure is removed and a function of maintaining an appropriate shape when air pressure is applied.

In addition, the wearable part 20 includes an elastic part 25 separately configured at a part in contact with the patient's back. The elastic part 25 is made of the same material as the outer surface 21 and the inner surface 22, but is sealed in a state of communication with yarn. That is, it is distinguished from the space 2 between the outer surface 21 and the inner surface 22, and air pressure is provided separately.

The elastic part 25 is disposed on the patient's back and serves to additionally elastically support the patient's body weight.

The through hole 52 is coupled to the connection pipe 90 and communicates with the breathing space 2 .

That is, when vacuum pressure is provided through the connection pipe 90, a negative pressure state is obtained, and in the negative pressure state, the abdomen is inflated to the front and the lungs are in a suction state in which external air is inhaled. And when the vacuum pressure is removed, the breathing space 3 expands, the abdomen contracts, and the air in the lungs is discharged to an exhalation state.

On the other hand, after the wearer 20 is worn by a patient, pneumatic pressure must be applied to exhibit appropriate elasticity.

That is, the degree of artificial respiration can be automatically adjusted by increasing the oscillation range of the control motor 78 when the oxygen saturation is low and lowering the oscillation range when the saturation is high.

Meanwhile, if necessary, the bellows 71 may be implemented by changing the shape of a piston cylinder, and at this time, the operating unit 72 drives the piston.

Meanwhile, a UV sterilizer may be added to purify the air discharged through the connection hose 76, and a dehumidifier may be added to control air humidity.

In addition, the operating module 60 may be configured to operate by an external power source, but may be implemented as a mobile type by providing a separate battery capable of being charged inside if necessary.
