1 is a view for explaining a device for measuring the skin sensation according to an embodiment of the present invention.

Referring to FIG. 1, the skin sensor measuring apparatus 100 according to an exemplary embodiment may include a mounting unit 110, a motor 120, a guide housing 130, a guide bar 140, and a main body 150. It may include at least one.

The apparatus 100 for measuring skin sensation according to an embodiment of the present invention may maintain a constant moving speed (contact speed) at which the skin sensor 10 moves toward the skin. As a result, measurement errors that may occur according to the speed at which the skin sensor 10 touches the skin may be solved. Hereinafter, each configuration will be described.

The skin sensor 10 may be a bone Frey meter. For example, the skin sensor 10 is a filament 20, the filament fixing unit 30 is fixed to one side and the filament fixing unit 30 is coupled to the cantilever 40 to rotate It may be made, including.

The skin sensor (10) may be fixed to the mounting unit (110) of the skin sensor (100). For example, the mounting unit 110 may be provided with a mounting hole 105, and one end of the cantilever 40 of the skin sensor 10 may be fitted to the mounting hole 105. Thus, it is possible to easily attach and detach the skin sensor of the desired grade to the mounting portion (110).

The motor 120 may provide a driving force for moving the mounting unit 110 in the skin direction, for example, in the Z axis direction. For example, the motor 120 may be a linear motor. When the motor 120 is driven, the mounting unit 110 may be raised and lowered in the Z-axis direction.

In this case, a potential meter may be provided to the motor 120 to control the movement of the motor 120. The motor 120 may be precisely controlled by a potential meter. As a result, the motor 120 may move the mounting unit 110 in the skin direction at a constant speed.

The guide housing 130 may have a U-shape with an open bottom. The motor 120 may be seated inside the upper side of the guide housing 130. Since the motor 120 is provided at the highest point of the opened U-shape, the motor 120 can stably provide a driving force to the mounting unit 110. In addition, a movement path through which the mounting unit 110 moves may be provided inside the guide housing 130. Accordingly, the guide housing 130 may exclude movement in other axial directions when the mounting portion 110 moves up and down in the Z-axis direction. Accordingly, the filament 20 coupled to the mounting portion 110 may move in the Z axis direction.

The guide bar 140 may be provided to be spaced apart from the guide housing 130 in the direction of the cantilever 40. The guide bar 140 may guide the movement path by being spaced apart in the width direction of the cantilever 40 so that the cantilever 40 moves in the Z-axis direction. To this end, the guide bar 140 may have, for example, a U-shaped opening. Thus, even when the one end of the cantilever 40 is coupled to the mounting portion 110, even if the cantilever 40 moves in accordance with the movement of the mounting portion 110, the filament provided at the other end of the cantilever 40 ( 20) can be stably moved in the Z-axis direction.

The main body 150 may provide a space in which a power supply unit required to drive the motor 120 is seated.

The skin sensor measuring apparatus 100 according to an embodiment of the present invention has been described above. Hereinafter, a method of measuring skin sensation according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

2 is a view for explaining a skin sensor measuring method according to an embodiment of the present invention. 3 and 4 are views for explaining in detail the skin sensor measuring method according to an embodiment of the present invention.

Referring to FIG. 2, in the method of measuring skin sensation according to an embodiment of the present disclosure, a step of preparing a skin sensation measuring device having a filament in direct contact with skin on one side (S110) and one end of the prepared skin sensation measuring device is provided. Mounting to the mounting portion (S120) and through the lifting motor connected to the mounting portion, it can be made, including the step of contacting the filament to the skin at a constant speed (S130). Each step will be described below.

Step S110

In operation S110, the skin sensor 10 may be prepared. That is, the operator may prepare a skin sensor (10) provided with a desired grade of filaments for measuring the sense of the skin.

Step S120

One end of the skin sensor may be mounted on the mounting unit prepared in step S120. That is, as shown in FIG. 3, a force in the m direction may be applied to fit one end of the skin sensor to the mounting hole 105. As the skin sensor 10 is coupled to the mounting unit 110, the filament 20 may be controlled to move at a constant speed according to the driving of the motor 120.

Step S130

In operation S130, the filament 20 may be in contact with the skin at a constant speed through the motor 120 connected to the mounting unit 110. For example, the motor 120 may control the mounting unit 110 at a speed of 1 mm / s to allow the filament to contact the skin at a speed of 1 mm / s.

Specifically, as shown in Figure 4 (a), the initial distance of the skin and the end of the filament 20 can be given as h1. At this time, as shown in Figure 4 (b), as the motor 120 lowers the mounting portion 110 at a constant speed, the distance between the skin and the end of the filament 20 can be reduced to h2. As shown in FIG. 4C, the skin and the filament 20 may contact each other by driving the additional motor 120.

According to one embodiment, when the distance between the skin and the filament end is more than a predetermined distance, the first control to quickly reduce the distance between the skin and the filament and the second control to keep the moving speed of the filament constant have. This is in consideration of a situation in which the time when the motor 120 moves the filament at a speed of 1 mm / s takes too long for the skin and the filament to contact each other. PI control may be utilized for the first control to quickly reduce the skin and filament within a predetermined distance, and P control may be utilized for the second control. Thereby, the measurement time can be shortened. For example, in FIG. 4A, the first control may be performed in the section of FIG. 4B, and in FIG. 4B, the second control may be performed in the section of FIG. 4C.

According to the skin sensory measuring device and the skin sensory measuring method according to an embodiment of the present invention, since the speed at which the filament moves toward the skin can be controlled constantly, the accuracy of the skin sensory measurement can be improved. Furthermore, with respect to the movement path of the skin sensor, since the guide bar and the guide housing are provided, unnecessary movement can be limited, so that the accuracy of the skin sensor can be improved.

Hereinafter, a skin elasticity measuring apparatus and a skin elasticity measuring method according to an embodiment of the present invention will be described with reference to FIGS. 5 to 7.

5 is a view for explaining a skin elasticity measuring method according to an embodiment of the present invention, Figure 6 and 7 is a view for explaining a skin elasticity measuring method according to an embodiment of the present invention in detail. .

Skin elasticity measuring device according to an embodiment of the present invention, it may be based on the skin sensor measurement device according to an embodiment of the present invention described above.

Furthermore, the skin elasticity measuring apparatus according to an embodiment of the present invention may further include a control unit for controlling the motor to obtain elasticity information of the surrounding skin based on the cancer occurrence point. The controller may obtain elasticity information of the surrounding skin by acquiring deformation of the skin while varying a force for pressing the skin by the filament through the motor. In addition, the skin elasticity measuring apparatus according to an embodiment of the present invention may further include a camera for obtaining an image of the skin in direct contact with the filament.

Referring to Figure 5, skin elasticity measuring method according to an embodiment of the present invention, the step of preparing a skin sensor measuring device having a filament in direct contact with the skin on one side (S210), of the prepared skin sensor At least one of mounting the one end to the mounting portion (S220) and controlling the motor connected to the mounting portion, by contacting the filament to a point around the cancer occurrence to obtain the elasticity information of the skin (S230) Can be done.

Steps S210 and S220 correspond to steps S110 and S120 described above, respectively, and thus a detailed description thereof will be omitted.

In operation S230, skin elasticity information may be obtained. According to an embodiment, the skin elasticity information may be used to determine a cancer metastasis path. More specifically, based on the point of cancer occurrence, the path of cancer metastasis is rigid, and then the skin is metastasized along the path. That is, the elasticity information of the skin can be used to predict the path of cancer metastasis.

Referring to FIG. 6, a cancer occurrence point CP is shown on the wrist, and cancer metastasis path candidate points SP1 to SP8 are shown around the cancer occurrence point. In this case, as described above, the filament may be sequentially contacted with the skin, that is, the cancer metastasis path candidate points SP1 to SP8 at a constant speed by driving a motor while the skin sensor is mounted on the mounting unit.

At this time, the force for pressing the skin with the filament can be increased through the motor while the filament is in contact with the skin. As the force of enjoying the skin with the filament increases, deformation of the skin may be produced. That is, the method may further include contacting the filament with a first force at a point around the cancer occurrence, measuring deformation of the skin, and contacting the filament with a second force at a point around the cancer occurrence, and measuring deformation of the skin. It is.

Referring to FIG. 7, the filament may be contacted to the cancer metastasis path candidate point SP1 based on the cancer occurrence point CP. The X axis of FIG. 7A is a time axis starting from the point of time when the filament is in contact with the skin. As shown in FIG. 7A, when the force for pressing the skin with the filament through the motor increases, deformation occurs in the direction in which the skin enters downward. As a result, since the cancer metastasis path candidate point SP1 has a general skin elasticity, it may be determined that the cancer metastasis path candidate point SP1 is not a path for cancer to metastasize.

The filament may then be contacted with the cancer metastasis path candidate point SP2 based on the cancer occurrence point CP. As shown in FIG. 7B, in spite of the fact that the force of pressing the skin with the filament through the motor increases, the deformation of the skin hardly occurs, it may be determined that the skin is hard for cancer metastasis. If it is determined that the elastic force of the skin is maintained as the cancer metastasis path candidate points SP3 to SP8 as shown in FIG. 7A, the controller may determine that the cancer has metastasized toward the SP2 point (P in FIG. 6). Can be.

According to the skin cell elasticity measuring apparatus and the skin elasticity measuring method according to an embodiment of the present invention, by taking into consideration that the skin is hardened along the anticipated cancer metastasis path, by obtaining the skin elasticity information of the surrounding cancer occurrence point In this way, it can provide preliminary information in which direction the cancer has spread. Furthermore, since the skin elasticity measuring apparatus and the skin elasticity measuring method according to an embodiment of the present invention are also based on the above-described skin sensor measuring apparatus and skin sensor measuring method, it is possible to provide high skin characteristic measuring accuracy.

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment and should be interpreted by the attached Claim. In addition, those of ordinary skill in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
