On the other hand, the shape memory alloy wire is Ni (nickel) and Ti (titanium) alloyed in a ratio of 50:50, and is formed to exhibit pseudo-elastic behavior through heat treatment and training process. That is, the transformation between the austenite and martensite phases occurs smoothly by stress at room temperature, and in particular, the shape memory characteristics returning from the martensite to austenite occur at room temperature. The austenite transformation start temperature and completion temperature are both controlled below room temperature and are formed to exhibit pseudo-elastic behavior.

The heat treatment of the shape memory alloy wire undergoes a training process to repeatedly deform and restore at a temperature above the austenite transformation temperature, and the transformation from austenite to martensite is further improved. When tensile stress is finally applied at room temperature, austenite to martensite phase transformation occurs, and the strain shows about 5% or more of strain and the stress change during deformation is very small. When a certain stress is added to the strain, and when the stress is removed also the transformation from martensite (austenite) to austenite (austenite) can show a contraction of about 5% or more.

Next, the processor 330 adjusts the air pressure in the sound pressure frame 100 to the negative pressure through the control of the electronic air pump 310, and converts the output of the pressure measuring sensor 320 into a pressure value. .

Next, the receiver 340 receives the set value transmitted by the transmitter 400 to be described below, the pressure value measured by the pressure measuring sensor 320 and converted by the processor 330 To transmit to the transmitter 400. As shown in FIG. 1, the receiver 340 is provided at the rear of the sound pressure controller 300 so that the pressure value converted by the processor 330 can be transmitted to the receiver 340.

In addition, as shown in FIG. 8, the receiver 340 may receive the pressure value and the set value by the transmitter 400 and Bluetooth or Wi-Fi.

Next, as shown in FIG. 1, the hose 200 connects the sound pressure frame 100 and the sound pressure control unit 300, and the air pressure controlled by the sound pressure control unit 300 is the sound pressure. To the mold 100. More specifically, the hose 200 connects the bottom pad 110 and the negative pressure control unit 300.

Next, the transmitter 400 newly sets the pressure inside the sound pressure frame 100 by using the pressure inside the sound pressure frame 100 and the physical condition of the user, and sets the set value to the sound pressure. It transmits to the control part 300. More specifically, as shown in FIG. 8, the transmitting unit 400 includes a pressure determining unit 410 and a pressure command unit 420.

The pressure determining unit 410 renews the pressure inside the sound pressure frame 100 for treating the concave chest of the user by using the pressure value measured by the pressure measuring sensor 320 and the user's physical condition. Set to calculate the set value.

In addition, the pressure command unit 420 transmits the set value set by the pressure determining unit 410 to the receiving unit 340.

As shown in Figure 3, the negative pressure control unit 300 and the transmitting unit 400 by the concave chest pressure of the user can be feedback-controlled to further increase the treatment efficiency, and can be adjusted by measuring the pressure in real time It works.

In the following, as shown in Figure 10, it will be described in more detail by the manufacturing method of the concave chest treatment device manufactured by the user customized.

First, a first step (S100) is a photographing step of tomography of the user's rib cage. More specifically, the photographing step (S100) tomography the concave chest area including the user's chest to generate three-dimensional shape information of the user's concave chest area. The generated three-dimensional shape information of the user's concave chest is input to a computer.

Next, the second step (S200) simulates the post-wear state of the user by producing a brace image through the computer to the three-dimensional shape information of the user's concave breast area. Simulating a post-wear condition such as whether the body is matched with the user's body, ie, the user's rib cage and concave breasts. The brace image is to be manufactured according to the body shape of the user to manufacture the upper panel pad 120.

Next, a third step (S300) is a model production step for producing the sound pressure frame 100, after the simulation step by using the user concave breast portion three-dimensional shape information corresponding to the actual user concave breast portion Build a therapeutic model.

Next, the fourth step (S400) is formed by adjusting the size and shape of the treatment device model produced in the model production step corresponding to the user concave breast portion.

As described above, the treatment device model is preferably provided in a convex shape so that the air can be vacuumed therein.

Next, the fifth step (S500) may be additionally performed to the treatment device model produced by the molding step of the fourth step (S400). In the fifth step S500, the bottom pad 110 is manufactured from silicon or rubber along a side edge where the concave chest part of the user abuts and is fixed with a shape memory alloy wire.

More specifically, in the manufacturing step (S500) of the bottom pad 110, the shape memory alloy wire is manufactured by alloying the Ni (nickel) and Ti (titanium) in a ratio of 50:50, heat treatment and training Through the process, pseudo-elastic behavior is formed to show a shrinkage of 5 to 10%.

The shape memory alloy wire is first manufactured by heat treatment at a temperature higher than or equal to the austenite transformation and the shape of the negative pressure mold 100, and then maintained at 10 to 12 hours at room temperature to repeat the deformation and the present application. Conduct a training course. The heat treatment and the training process maintained at room temperature are repeatedly performed 5 to 6 times to make the transformation from austenite to martensite (martensite) more smoothly, and to add tensile stress at room temperature. .

 It is preferable to perform heat processing at 800-850 degreeC. If the heat treatment is less than 800 ℃ low hardness and low phase transformation does not include a shrinkage of 5 to 10% and there is a fear that the air pressure can not be maintained when the inside of the negative pressure frame 100 to be in a vacuum state, the heat treatment is 850 When the temperature exceeds the ℃, since the contracted stress of the negative pressure mold 100 may be insignificant, it may be difficult to add a constant pressure to the calibration site.

In addition, the shape memory alloy wire may have a very small degree of change in stress when kept at room temperature for less than 10 hours, and may not add a constant stress during tension, and repeat the heat treatment when kept at room temperature for more than 12 hours. When the expansion of the expansion is insignificant, it may be difficult to expand the sound pressure frame 100 manufactured by the present invention.

In addition, when the shape memory alloy wire is not trained at room temperature and is carried out at a temperature below room temperature or at a temperature exceeding room temperature, since the service life of the manufactured negative pressure mold 100 may be lowered, it is preferable to carry out at room temperature. .

By the means for solving the above problems, the present invention can automatically adjust the pressure of the sound pressure frame 100 provided to treat concave breasts.

In addition, the present invention can produce an adjustable concave chest treatment device by measuring the pressure in real time.

In addition, the present invention after measuring the pressure of the patient's chest, the concave chest treatment device provided with an external information transmitting and receiving unit 340 to determine the pressure by the value set according to the treatment purpose of the individual patient, and to control the pressure Can be prepared.

In addition, the present invention can manufacture a concave chest treatment device that can be negative pressure only the concave chest area without pressing the entire chest of the user.

In addition, the present invention tomography of the user's rib cage, based on the image taken by the computer simulates the state after wearing the present concave chest treatment device after providing a brace for the user according to the shape derived through the simulation It has an effect of increasing chest correction efficiency.

In addition, the present invention is a pseudo-elastic deformation according to the change of the thoracic volume by the user's breath through the shape memory alloy wire having a pseudoelastic (super-elastic) behavior characteristics so that the user's body parts are negative pressure, the inconvenience of the user's breathing There is an effect that can be minimized.
