Description

Ultrasonic treatment device and its control method {ULTRASOUND TREATMENT DEVICE AND IT`S CONTROL METHOD}

The present invention relates to an ultrasonic treatment device and a control method that allows ultrasonic waves to be irradiated only when the ultrasonic treatment device and the user's skin are in complete contact during the ultrasound treatment process.

Recently, interest in skin care and obesity treatment is increasing day by day, and various medical and beauty devices for skin care and obesity treatment are being developed. For example, various skin care devices are being developed for patients who wish to undergo face lifting or skin tightening procedures.

A non-invasive ultrasound device that has recently been in the spotlight is an ultrasound treatment device that uses high intensity focused ultrasound (HIFU). This type of ultrasound treatment device irradiates high-intensity focused ultrasound to shallow skin tissue for skin beauty treatment to perform skin lifting or skin tightening procedures, and for obesity treatment, high-intensity focused ultrasound is irradiated to the subcutaneous fat layer to tighten fatty tissue. There is an ultrasonic treatment device that burns or melts and decomposes.

Here, when using high-intensity focused ultrasound, it is very important to ensure that the high-intensity focused ultrasound can be irradiated while the ultrasound treatment device is in complete contact with the treatment area.

For example, in order to treat obesity, high-intensity focused ultrasound must be irradiated only to the subcutaneous fat layer, which is the target layer, in the skin layer consisting of the stratum corneum, epidermis, dermis, subcutaneous fat, and muscle layer to burn or melt and decompose the fat tissue.

If high-intensity focused ultrasound is irradiated while the ultrasound treatment device is not in proper contact with the treatment area, not only will the ultrasound not be properly irradiated to the subcutaneous fat layer, but the high-intensity focused ultrasound will be incorrectly focused on a skin layer other than the subcutaneous fat layer. This may cause serious side effects, such as burns on the user's skin.

In addition, it is necessary to place the ultrasound treatment device on various body parts to perform the treatment. In this case, the curvature of the skin is different depending on the user's body part, the elasticity of the skin is different, and the thickness of the subcutaneous fat layer is also different. In other words, the angle or force applied by the user to contact the ultrasonic treatment device to the skin varies depending on the treatment area, so if this is not taken into consideration, there are limitations to ultrasonic treatment.

Therefore, in order to solve the above-mentioned problem, a means is needed to consider the treatment area where the ultrasonic treatment device is located, determine whether the treatment area is in contact with the user's skin, and enable ultrasonic waves to be radiated.

The present invention provides an ultrasonic treatment device and a control method thereof.

The motion recognition sensor 160 can sense the movement of the ultrasonic treatment device 100. Referring to FIG. 2 together, the motion recognition sensor 160 may be located in the grip unit 10. More specifically, the motion recognition sensor 160 is located in the grip unit 10 and can sense at least one of movement, movement direction, acceleration, angular velocity, or inclination of the ultrasonic treatment device 100.

The pressure sensor module 170 can sense the pressure between one surface of the head unit 20 and the user's skin. Additionally, the control unit 180 may control the operation of the ultrasonic generator 150 based on the values sensed by the motion recognition sensor 160 and the pressure sensor module 170. This will be described in detail below.

The control unit 180 may control all or part of the components included in the ultrasonic treatment device 100. For example, the control unit 180 may control the input unit 110, the output unit 120, the ultrasonic generator 150, the motion recognition sensor 160, and the pressure sensor module 170.

In particular, in the ultrasonic treatment device 100 according to an embodiment of the present invention, the control unit 180 drives the ultrasonic generator 150 based on the values sensed by the motion recognition sensor 160 and the pressure sensor module 170. can be controlled. That is, the control unit 180 can determine the treatment area where the ultrasonic treatment device 100 is located through the motion recognition sensor 160, and can determine one side of the head 20 and the user's area through the pressure sensor module 170. It is possible to determine whether there is contact with the skin. In addition, the ultrasonic treatment device 100 is located at the treatment area and the ultrasonic generator 150 can be controlled to operate only when the user's skin is completely contacted.

Meanwhile, the block diagram of the ultrasonic treatment device 100 shown in FIG. 1 is only a block diagram for one embodiment of the present invention, and each component of the block diagram is integrated according to the specifications of the ultrasonic treatment device 100 that is actually implemented. , may be added, or omitted.

That is, as needed, two or more components may be combined into one component, or one component may be subdivided into two or more components. In addition, the functions performed in each block are for explaining embodiments of the present invention, and the specific operations or devices do not suggest the scope of the present invention.

Figure 2 is a diagram showing the overall shape of the ultrasonic treatment device 100 according to an embodiment of the present invention, including a grip portion 10 held by the user, a head portion 20 coupled to one side of the grip portion 10, and the head. It may include an ultrasonic generator 150 located on one side of the unit 20.

Here, the grip portion 10 may include a detachment button 11 formed on the side that serves to couple or separate the head portion 20.

Figure 3 is a diagram showing a preset treatment area 40 where the ultrasonic treatment device 100 according to an embodiment of the present invention is located. Figures 4 and 5 are diagrams for explaining a sensing method by the motion recognition sensor 160 of the ultrasonic treatment device 100 according to an embodiment of the present invention.

The ultrasound treatment device 100 according to an embodiment of the present invention may be located at a preset treatment area 40 including the user's thigh, abdomen, buttocks, calf, etc. Here, referring to FIG. 1 as well, the preset treatment area 40 may be stored in the storage unit 140.

And the ultrasonic treatment device 100 according to an embodiment of the present invention burns, melts, and decomposes the fat tissue in the subcutaneous fat layer by irradiating high-intensity focused ultrasound to a depth corresponding to the subcutaneous fat layer among the skin layers of the preset treatment area 40. It can be used to treat obesity.

Before irradiating high-intensity focused ultrasound, it is necessary to first determine whether the ultrasound treatment device 100 is located in the preset treatment area 40. This is because, as described above, the thickness of the skin layer consisting of the stratum corneum, epidermis, dermis, subcutaneous fat, and muscle layer is different for each treatment area 40, and the thickness of the subcutaneous fat layer, which is the target layer, is also different accordingly. For example, if high-intensity focused ultrasound is irradiated to the face of a user whose skin layer is relatively thinner than the treatment area 40 described above, side effects may occur.

In addition, since the curvature of the skin is different and the elasticity of the skin is different for each treatment area 40, the ultrasonic treatment device 100 is preset even when determining whether one surface of the head 20, which will be described later, is in contact with the user's skin. It is necessary to determine whether it is located in the treatment area 40.

Referring to FIG. 2 together, the ultrasonic treatment device 100 according to an embodiment of the present invention can sense the movement of the ultrasonic treatment device 100 through the motion recognition sensor 160 located in the grip unit 10. . More specifically, the movement sensed by the motion recognition sensor 160 may include at least one of movement, movement direction, acceleration, angular velocity, or inclination of the ultrasonic treatment device 100.

And, based on the value sensed by the motion recognition sensor 160, the first condition of whether the ultrasonic treatment device 100 is located in the preset treatment area 40 is determined through the control unit 180 described above in FIG. 1. You can.

In addition, the motion recognition sensor 160 of the ultrasonic treatment device 100 according to an embodiment of the present invention may include a 9-axis sensor including a 3-axis acceleration sensor, a 3-axis gyro sensor, and a 3-axis magnetic field sensor. . And, by sensing the X, Y, and Z vector values through the 9-axis sensor, at least one of the movement, movement direction, acceleration, angular velocity, or inclination of the ultrasonic treatment device 100 described above can be sensed.

That is, the movement of the ultrasound treatment device 100, including three-dimensional movement, speed, rotation, etc. of the ultrasound treatment device 100, can be sensed through the X, Y, and Z vector values. In addition, the first condition of whether the ultrasonic treatment device 100 is located in the preset treatment area 40 can be determined through the control unit 180 using the sensed vector value.

FIG. 4 is a diagram for explaining a method of sensing displacement due to movement of the ultrasonic treatment device 100. As shown in FIG. 4, when the ultrasound treatment device 100 moves from the P position to the Q position, displacement occurs. At this time, the motion recognition sensor 160 can sense displacement in the three-axis coordinate system of the x-axis, y-axis, and z-axis through Equation 1 below.

[Equation 1]

That is, the control unit 180 senses the displacement resulting from the movement of the ultrasonic treatment device 100 and selects the treatment area 40 where the ultrasonic treatment device 100 is moving from among the preset treatment areas 40 shown in FIG. 3. It can be judged through. Additionally, the first condition of whether the ultrasonic treatment device 100 is located in the preset treatment area 40 may be determined.

FIG. 5 is a diagram for explaining a method of sensing the tilt of the ultrasonic treatment device 100. When the ultrasonic treatment device 100 is tilted at an angle of θ according to the movement of the ultrasonic treatment device 100, the motion recognition sensor 160 detects ultrasonic waves through X, Y, and Z vector values as shown in FIG. 5. The tilt of the surgical device 100 can be sensed through Equation 2 below.

[Equation 2]

Here, m is the mass of the ultrasonic treatment device 100, and g is the gravitational acceleration.

Through Equation 2 above, the ultrasonic treatment device 100 according to an embodiment of the present invention senses the inclination of the ultrasonic treatment device 100 and detects the ultrasound treatment device ( The treatment area 40 where 100 is located can be determined through the control unit 180. Additionally, the first condition of whether the ultrasonic treatment device 100 is located in the preset treatment area 40 can be determined.

In order to sense the movement of the above-described ultrasonic treatment device 100, it is necessary to set the initial value when the ultrasonic treatment device 100 is left alone before using it.

Therefore, in order to set the initial value, the value when the ultrasonic treatment device 100 is left alone is measured a certain number of times, the average value is obtained, and the calibration process is performed to set the value as a reference value. Additionally, the user can set an initial value before the ultrasonic treatment device 100 moves by pressing the drive button 115 located on the operation unit 30 described above in FIGS. 1 and 2. And the control unit 180 described above with reference to FIG. 1 can control the ultrasonic generator 150 not to operate at the set initial value.

For example, if the inclination when the ultrasonic treatment device 100 is placed on a flat ground is set to the initial value before using the ultrasonic treatment device 100, the ultrasonic generator 150 may not operate at that inclination. You can.

In addition, through the above-described method, the ultrasonic treatment device 100 according to an embodiment of the present invention can prevent a user from attempting to perform a treatment using the ultrasonic treatment device 100 while lying down for safety reasons. That is, when the user is lying down, even if the ultrasonic treatment device 100 is positioned at the preset treatment area 40 described above in FIG. 3, the change in inclination from the set initial value can not be sensed. In this case, the control unit 180 may determine that the first condition described above is not satisfied and control the ultrasonic generator 150 not to operate.

That is, as described above, the movement of the ultrasonic treatment device 100 can be sensed by comparing the value sensed through the motion recognition sensor 160 with the set initial value, and through this, the control unit 180 detects the movement of the ultrasonic treatment device 100. ) can determine the first condition of whether or not it is located in the preset treatment area 40.

Figure 6 is a view of the head portion 20 of the ultrasonic treatment device 100 according to an embodiment of the present invention viewed from below.

Referring to FIG. 2 together, the head portion 20 is coupled to one side of the grip portion 10, and one surface of the head portion 20 may be in contact with the user's skin. And an ultrasonic wave generator 150 may be located on one side of the head unit 20.

The pressure sensor module 170 is located on one side of the head unit 20 and may serve to sense the pressure against the user's skin. Additionally, a plurality of pressure sensor modules 170 may be located along the outer edge of one side of the head portion 20 and spaced apart from each other.

As described above with reference to FIG. 1, the control unit 180 can determine the second condition of whether one surface of the head unit 20 is in contact with the user's skin based on the value sensed by the pressure sensor module 170. there is. In particular, the control unit 180 calculates the deviation value of the value sensed by each of the plurality of pressure sensor modules 170, compares the calculated deviation value with the standard deviation value, and if it exceeds the standard deviation value, the head unit ( It can be determined that one side of 20) is not in contact with the user's skin.

Therefore, the ultrasonic treatment device 100 according to an embodiment of the present invention uses the ultrasonic generator 150 in the control unit 180 only when one surface of the head unit 20 and the user's skin come into contact through the pressure sensor module 170. ) can operate.

In particular, the control unit 180 determines the first condition of whether the ultrasonic treatment device 100 is located at the preset treatment area 40 shown in FIG. 3 and whether one surface of the head unit 20 is in contact with the user's skin. If all of the second conditions are satisfied, the ultrasonic generator 150 can be operated.

Here, the standard deviation value may vary based on preset characteristic information of the treatment area 40. And the characteristic information of the preset treatment area 40 may include information about curvature, elasticity, and thickness of the fat layer.

This is because the curvature of the skin is different depending on the treatment area 40, the elasticity of the skin is different, and the thickness of the subcutaneous fat layer is also different. For example, the subcutaneous fat layer of the abdomen is thicker than that of other treatment areas 40, so the overall pressure applied to one surface of the head 20 may not be the same.

In other words, the angle or force applied by the user to contact the ultrasonic treatment device 100 with the skin may vary depending on the treatment area 40, and therefore, the pressure value simply sensed without considering the treatment area 40. There are limitations in determining whether or not there is contact with the skin solely based on the method.

Therefore, referring to FIGS. 1 and 3 together, the ultrasound treatment device 100 according to an embodiment of the present invention may store a reference deviation value in the storage unit 140. Additionally, the control unit 180 may determine the second condition by receiving a standard deviation value from the storage unit 140 based on the determination of the above-described first condition. For example, in the case of the abdomen, the standard deviation value may be stored as a larger value than the standard deviation value of other treatment areas 40.

Through this, the deviation value of the value sensed by each of the plurality of pressure sensor modules 170 is compared with the standard deviation value provided from the storage unit 140, and when the standard deviation value is exceeded, one side of the head unit 20 is It can be judged that it does not come into contact with the skin. In other words, it can be determined that the second condition is not satisfied. And in this case, the ultrasonic generator 150 may not operate.

The ultrasonic generator 150 may include a first vibrator 151 that generates high-intensity focused ultrasonic waves. Through the high-intensity focused ultrasound generated by the first vibrator 151, the ultrasound treatment device 100 according to an embodiment of the present invention can be used for skin lifting or skin tightening procedures, and in particular, can burn fat tissue in the subcutaneous fat layer or It can be used to treat obesity by melting and decomposing it.

Additionally, the ultrasonic generator 150 may include a second vibrator 153 of a planar type. Here, the second vibrator 153 can generate planar ultrasound, and can emulsify fat in the subcutaneous fat layer in the above-described obesity treatment through planar ultrasound.

That is, treatment of obesity by emulsifying fat in the subcutaneous fat layer through the second vibrator 153 of the flat type and burning or melting and decomposing the fat tissue in the subcutaneous fat layer through the first vibrator 151 that generates high-intensity focused ultrasound. The effect can be further improved.

And the ultrasonic generator 150 may include a plurality of first vibrators 151 and second vibrators 153. In this case, the plurality of first vibrators 151 and second vibrators 153 have various shapes. can be placed.

FIG. 7 is a diagram illustrating the shape of the pressure sensor module 170 in the ultrasonic treatment device 100 according to an embodiment of the present invention. Figure 7 (a) is a diagram showing the overall shape of the pressure sensor module 170 combined, and Figure 7 (b) is an exploded view of the pressure sensor module 170. FIG. 8 is a cross-sectional view taken along line A-A′ of FIG. 7(a), and FIG. 9 is a cross-sectional view of another embodiment of the pressure sensor module 170 in the ultrasonic treatment device 100 of the present invention. And Figure 10 is a view from below of another embodiment of the head portion 20 in the ultrasonic treatment device 100 of the present invention.

Referring to Figure 6 together, the pressure sensor module 170 protrudes from one surface of the head portion 20 and the cap 171 is subjected to pressure due to contact with the skin. Displacement occurs due to the pressure applied to the cap 171. It may include a pressing member 172 and a pressure sensor 173 pressed by the pressing member 172.

Here, the pressure sensor module 170 may include a body 174, and the pressing member 172 may be positioned penetrating the body 174. In addition, the elastic member 175 that applies elastic force according to the displacement of the pressing member 172 may be coupled to the pressing member 172. Additionally, the cap 171 may be coupled to the upper side of the body 174, and the pressure sensor 173 may be coupled to the lower side of the body 174 while located in the sensor holder 176.

Referring to FIG. 8, the cap 171 may include a groove portion 171a. A pressing member 172 may be fitted and coupled to the groove portion 171a. In this case, the groove portion 171a may be formed in a shape corresponding to the shape of the pressing member 172, and a plurality of groove portions 171a may be formed. And when pressure is applied to the cap 171, displacement occurs in the pressing member 172 and can pressurize the pressure sensor 173.

Here, the cap 171 may be formed of a soft material such as silicone so that displacement may occur in the pressing member 172 when pressure is applied in contact with the user's skin. Additionally, the cap 171 may be made of an elastic material to have a repulsive force when pressure is applied through contact with the user's skin, and may be formed to have a predetermined hardness.

The pressure sensor 173 may detect the pressure applied by the pressing member 172 and output an electrical signal corresponding to the magnitude of the detected pressure. And referring to FIG. 1 , the pressure sensor 173 may transmit an electrical signal representing the sensed pressure to the control unit 180. For this purpose, the pressure sensor 173 may be electrically connected to the control unit 180.

In the pressure sensor module 170, the pressing member 172 may be assembled in a state in contact with or pressing the pressure sensor 173. In this case, the pressure sensor 173 detects the difference between the initial pressure before the cap 171 and the user's skin come into contact with the pressure applied to the pressure sensor 173 when the user's skin comes into contact with the cap 171, and the control unit ( 180) can be transmitted as an electrical signal.

FIG. 9 is a cross-sectional view of various embodiments of the pressure sensor module 170 in the ultrasonic treatment device 100 of the present invention. FIG. 9 (a) shows the pressure sensor module 170 when the cap 171 has a hemispherical shape. It is a cross-sectional view, and Figure 9(b) is a cross-sectional view of the pressure sensor module 170 when the cap 171 has a square block shape.

Here, the cap 171 may have a hemispherical shape or a square block shape. This is to expand the contact area of the cap 171, where pressure is applied by contact with the user's skin.

As described above with reference to FIG. 3, the ultrasonic treatment device 100 according to an embodiment of the present invention can be located in various treatment areas 40, so it has different curvature, elasticity, and thickness of the fat layer for each treatment area 40. There is a need to respond. Therefore, the accuracy of the value sensed by the pressure sensor module 170 can be improved by forming the cap 171 in various shapes to correspond to the various treatment areas 40.

In addition, the cap 171 may be provided with a groove portion 171a, and the pressing member 172 may be fitted and coupled to the groove portion 171a. Accordingly, the groove portion 171a and the groove portion 171a provided on the cap 171 ) The shape of the pressing member 172 inserted into the cap 171 may be a hemispherical shape or a square block shape corresponding to the shape of the cap 171.

Since the pressure member 172 is displaced by the pressure applied to the cap 171, if the shape of the cap 171 and the shape of the pressure member 172 are the same, the accuracy of the value sensed by the pressure sensor module 170 can be improved. It can be improved.

Figure 10 is a view from below of another embodiment of the head portion 20 in the ultrasonic treatment device 100 of the present invention.

A plurality of pressure sensor modules 170 may be located along the outer edge of one side of the head unit 20 and spaced apart from each other. And referring to FIG. 7 , the pressure sensor module 170 may include a cap 171 protruding from one surface of the head portion 20. Here, the ultrasonic treatment device 100 according to an embodiment of the present invention may further include a pressure transmission member 190 that is provided along the outer edge of one surface of the head portion 20 and covers the cap 171.

The pressure transmission member 190 may serve to transmit pressure due to contact with the user's skin to the cap 171. In sensing the pressure between one surface of the head unit 20 and the user's skin through the pressure transmission member 190, the contact area in contact with the skin can be expanded. Additionally, the pressure transmission member 190 may be made of a soft material so that pressure can be transmitted to the cap 171 when pressure is applied through contact with the skin.

FIG. 11 is a diagram for explaining a control method of the ultrasonic treatment device 100 according to an embodiment of the present invention.

First, as described above with reference to FIGS. 1 and 2 , the user turns on the ultrasound treatment device 100 through the power button 111 and selects the operation time, timer setting, and ultrasonic intensity through the mode selection button 113. You can set steps, etc. and press the drive button 115. And the ultrasonic treatment device 100 can be moved for ultrasonic treatment.

And the movement of the ultrasonic treatment device 100 can be sensed through the motion recognition sensor 160 (S110). More specifically, at least one of movement, movement direction, acceleration, angular velocity, or inclination of the ultrasonic treatment device 100 may be sensed through the motion recognition sensor 160.

Based on the value sensed by the motion recognition sensor 160, the first condition of whether the ultrasonic treatment device 100 is located in the preset treatment area 40 may be determined (S120). This is because, as described above in FIGS. 3 to 5, it is necessary to first determine whether the ultrasonic treatment device 100 is located in the preset treatment area 40 before irradiating ultrasound.

The thickness of the skin layer consisting of the stratum corneum, epidermis, dermis, subcutaneous fat, and muscle layer is different for each treatment area 40, and the thickness of the subcutaneous fat layer, which is the target layer, is also different accordingly. In addition, because the curvature of the skin is different and the elasticity of the skin is different for each treatment area 40, the overall pressure applied to one surface of the head unit 20 may not be the same. Therefore, as described above, when determining whether one surface of the head 20 is in contact with the user's skin, it is necessary to determine whether the ultrasonic treatment device 100 is located in the preset treatment area 40.

Here, if the ultrasonic treatment device 100 is not located in the preset treatment area 40, that is, if the first condition is not satisfied, the ultrasonic treatment device 100 located in the manipulation unit 30 as described above with reference to FIGS. 1 and 2 A notification can be output on screen or by voice through the display unit 121 and the audio output unit 123 (S160).

Here, the notification may include a notification requesting the user to readjust the position of the ultrasonic treatment device 100 because the ultrasound treatment device 100 is not located in the preset treatment area 40.

When the ultrasonic treatment device 100 is located in the preset treatment area 40, that is, when the first condition is satisfied, the pressure between one surface of the head portion 20 of the ultrasonic treatment device 100 and the user's skin is applied. It can be sensed through the pressure sensor module 170 (S130).

Here, the second condition of whether one surface of the head unit 20 is in contact with the user's skin can be determined based on the value sensed by the pressure sensor module 170 (S140). In particular, as described above with reference to FIG. 6, the ultrasonic treatment device 100 according to an embodiment of the present invention includes a plurality of pressure sensor modules 170 located spaced apart from each other along the outer edge of one surface of the head portion 20. It can be included. Then, the deviation value of the value sensed by each of the plurality of pressure sensor modules 170 is calculated, compared with the standard deviation value, and if it exceeds the standard deviation value, it can be determined that the second condition is not satisfied.

If one surface of the head unit 20 is not in contact with the user's skin, that is, if the second condition is not satisfied, the screen or Notifications can be output by voice (S160).

Here, the notification may include a notification requesting that the ultrasonic treatment device 100 be brought into contact with the user's skin again because one surface of the head unit 20 is not in contact with the user's skin.

When one surface of the head unit 20 is in contact with the user's skin, that is, when both the first and second conditions described above are satisfied, the ultrasonic generator 150 can be operated by the control unit 180 (S150) ). And the ultrasonic generator 150 may be operated based on the driving signal transmitted to the control unit 180 according to the settings by the user described above.

In addition, the control method of the ultrasonic treatment device 100 according to an embodiment of the present invention continuously determines the first condition of whether the ultrasonic treatment device 100 is located in the preset treatment area 40 and the head portion during the treatment. The above-described steps are repeated to determine the second condition of whether one surface of (20) is in contact with the user's skin and to operate the ultrasonic generator 150 only when both the first and second conditions are satisfied. can do.

The above detailed description should not be construed as restrictive in any respect and should be considered illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
