Smart insole device for preventing foot ulcers {SMART INSOLE DEVICE FOR PREVENTING FOOT ULCERS}

The present invention relates to a smart insole device, and more specifically, to a smart insole device that can prevent the occurrence of foot ulcers by monitoring the pressure applied to the feet and notifying the user when abnormal pressure occurs.

Diabetes is a metabolic disease that occurs due to insufficient insulin secretion or normal function. When people suffer from conditions such as diabetes, blood circulation is poor, senses are dulled, and resistance to bacterial infections is reduced.

Accordingly, even if a wound occurs on the foot, it is difficult to feel it, and the healing ability and resistance to bacteria are low, so even minor wounds progress rapidly, causing frequent complications such as ulcers and gangrene.

Foot injuries can occur in various forms, especially when excessive pressure is continuously applied to a specific area. However, because the sensation in the feet is dulled due to conditions such as diabetes, in most cases, people are not aware that excessive pressure is being applied. Accordingly, there is a demand for technology that can prevent the occurrence of foot ulcers at an early stage by monitoring abnormal pressure applied to the feet.

The purpose of the present invention, which was devised to solve the above-mentioned problems, is to provide a smart insole device that can prevent the occurrence of foot ulcers in advance by sending a warning message to the user when excessive pressure is applied to the feet. .

Referring to Figures 1 and 2, the smart insole device 100 according to an embodiment of the present invention may be installed inside the shoe 10. The shoe 10 may include an outsole (11), a midsole (not shown), a smart insole device (100), an upper structure (12), etc. The outsole 11 refers to a portion located at the bottom of the shoe 10 and in contact with the ground. For example, the outsole 11 may be made of a material such as leather, rubber, or silicone, but is not limited thereto.

The midsole (not shown) may be disposed on the upper side of the outsole 11 and may serve to absorb and disperse shock applied to the foot during walking and driving. This midsole can be omitted or integrated into the outsole 11 as needed.

The upper structure 12 may be connected to the outsole 11 or midsole to provide an opening 13 and an internal space for the foot to enter. For example, the superstructure 12 may be formed from a variety of materials, such as leather, artificial leather, natural or synthetic fabric.

The smart insole device 100 may be inserted into the shoe 10 through the opening 13 of the upper structure 12 and may be placed on the upper side of the outsole 11 or midsole.

Figure 3 is a diagram showing a pressure sensing module according to an embodiment of the present invention, Figure 4 is a diagram showing the sole of the foot, Figure 5 is a diagram showing the disassembled state of the smart insole device according to an embodiment of the present invention, and Figure 6 is a diagram showing the combined internal configuration of the smart insole device according to an embodiment of the present invention, and Figure 7 is a diagram showing a cover member and a buffer member according to an embodiment of the present invention.

Referring to FIGS. 3 to 6 , the smart insole device 100 according to an embodiment of the present invention may include a body member 110, a pressure sensing module 120, and a control module 130.

The body member 110 forms the basic body of the smart insole device 100 and has a size corresponding to the user's foot.

The pressure sensing module 120 is installed on the body member 110 and may include a plurality of pressure sensors 121, 122, 123, and 124 that sense pressure applied by the foot in each region. For example, the plurality of pressure sensors 121, 122, 123, and 124 include a first pressure sensor 121, a second pressure sensor 122, a third pressure sensor 123, and a fourth pressure sensor 124. It can be included.

The first pressure sensor 121 is positioned to correspond to the front part of the foot where the metatarsal is located, and can measure the pressure applied from the front part of the foot. For example, there may be three first pressure sensors 121, and each of the three first pressure sensors 121 may be arranged to be spaced apart from each other.

Among the three first pressure sensors 121, one first pressure sensor 121A located in the center can measure the pressure applied from the center of the metatarsal bone, and the remaining two first pressure sensors 121B are located at the center of the metatarsal bone. The pressure exerted on each side of the bone can be measured.

The second pressure sensor 122 is positioned to correspond to the heel and can measure the pressure applied from the heel.

The third pressure sensor 123 is positioned to correspond to the area between the front part of the foot and the heel and can measure the pressure applied to the area between the front part of the foot and the heel.

The fourth pressure sensor 124 is positioned to correspond to the toe and can measure the pressure applied from the toe.

Meanwhile, as shown in FIG. 4, for convenience of explanation, the front part of the foot is referred to as area F1, the heel is referred to as area F2, the area between the front part of the foot and the heel is referred to as area F3, and the inside of the foot is referred to as area F4. That is, the first pressure sensor 121 can measure the pressure applied to the F1 area of the foot, and the second pressure sensor 122 can measure the pressure applied to the F2 area of the foot. Additionally, the third pressure sensor 123 can measure the pressure applied to the F3 area of the foot.

The pressure sensing module 120 as described above can accurately measure pressure applied to all areas of the foot, such as the front part of the foot where the metatarsal bone is located, the heel, the toes, and between the front part and the heel. Accordingly, analysis reliability can be improved in analyzing whether there is an abnormality in the pressure applied to the user's foot based on the pressure data measured by the pressure sensing module 120. For this purpose, the pressure sensing module 120 may be manufactured in the form of a flexible circuit board, for example, and may be electrically connected to the control module 130, which will be described later.

Additionally, the sealing member 170 may be coupled to a portion of the body member 110 where the pressure sensing module 120 is installed. Through this, the pressure sensing module 120 can be prevented from being damaged by external stimuli, and the sealing member 170 and the body member 110 can be joined using various methods such as heat fusion, adhesion, and sewing. can be used

The control module 130 can perform overall control operations of the smart insole device 100 to prevent foot ulcers. This control module 130 is connected to the pressure sensing module 120 and may be installed on the opposite side of the body member 110 where the pressure sensing module 120 is located. As such, in the smart insole device 100 according to an embodiment of the present invention, the control module 130 and the pressure sensing module 120 are located on opposite sides of the body member 110.

Additionally, the control module 130 may include a control unit 131a, a storage unit 131b, and a main board 131c.

The control unit 131a may control the operation and functions of the smart insole device 100 in conjunction with components such as the pressure detection module 120 and the motion sensor 138. For example, the control unit 131a may include at least one processor and may be mounted on the main board 131c.

The storage unit 131b may serve to store various data generated during the operation and function of the smart insole device 100. For example, the storage unit 131b may include at least one memory element and may be mounted on the main board 131c.

In addition, the main board 131c is electrically connected to the pressure sensing module 120, the antenna 133, the receiving coil for wireless charging (Rx), the battery 134, the vibration generating member 135, the motion sensor 138, etc. You can.

Meanwhile, the smart insole device 100 according to an embodiment of the present invention includes a connection member 132, an antenna 133, a receiving coil for wireless charging (Rx), a battery 134, a vibration generating member 135, and a motion sensor. (138) may be further included.

The connecting member 132 is installed to penetrate the body member 110 and connects the pressure sensing module 120 and the control module 130. For example, the connection member 132 may be a wire extending from the pressure sensing module 120.

The antenna 133 is installed to transmit and receive data with network-connected external components (e.g., user terminals, etc.), and may be electrically connected to the main board 131c through the antenna connection portion 136. That is, the antenna connection portion 136 may be connected to the antenna 133 in a state that is bent from the main board 131c toward one side of the body member 110.

In more detail, the antenna 133 may be located in a portion of the body member 110 adjacent to the outer foot blade. In contrast, when the antenna 133 is located on the inner part of the user's feet facing each other, the antenna 133 of one foot may cause interference in the process of transmitting pressure data due to spatial constraints caused by the other foot. You can.

However, as described above, the antenna 133 is located in a portion of the body member 110 adjacent to the foot blade, thereby preventing communication quality from being deteriorated due to interference with surrounding metallic parts. In addition, it is possible to easily secure a space for the antenna 133 to communicate with the user terminal and/or wireless charger.

The receiving coil (Rx) for wireless charging is connected to the main board (131c), and the control module 130 generates an induced current of the receiving coil (Rx) for wireless charging when the smart insole device 100 is placed on the wireless charger. By receiving it, charging of the battery 134 can be performed.

The battery 134 can be charged through the wireless charging receiving coil (Rx). The battery 134 may be implemented as a rechargeable secondary battery, and may be charged by the induced current of the receiving coil for wireless charging (Rx) generated by the transmitting coil for wireless charging of the wireless charger.

The vibration generating member 135 transmits vibration from the foot to the area between the front part and the heel. The vibration generating member 135 for this purpose is positioned to correspond to the third pressure sensor 123 and may be coupled to the main board 131c.

Differently, when the vibration generating member 135 is located in an area corresponding to the second pressure sensor 122 where relatively greater pressure is applied than other areas of the foot, the vibration generating member 135 is sufficiently affected by the user's body weight. Since it cannot vibrate, it may be difficult for the user to feel the vibration generated by the vibration generating member 135.

However, as described above, the vibration generating member 135 is located in the F3 area corresponding to the third pressure sensor 123, where relatively less pressure is applied than the heel, so that the user can easily avoid the vibration generated by the vibration generating member 135. It can be sensed clearly.

The vibration generating member 135 may be implemented as a vibration motor, etc., but is not limited thereto, and may be implemented as a known configuration capable of outputting vibration.

The motion sensor 138 may serve to detect foot movement. For example, the motion sensor 138 may be implemented by employing an Inertial Measurement Unit (IMU).

The control module 130 may detect the user's operating state based on the movement information measured by the motion sensor 138 and the pressure information measured by the pressure sensors 121, 122, 123, and 124.

At this time, the user's motion state may include standing in place, walking, running, and sitting.

For example, if little change in inertia in the 6th axis occurs through the motion sensor 138 and the pressure of both feet is detected at a certain level through the pressure sensors 121, 122, 123, and 124, the user's operating state remains in place. It can be detected in a standing state.

In addition, when the change in inertia of the Z-axis (ground direction) through the motion sensor 138 is continuously measured at a certain level (for example, 2G or more) and the number of steps per minute (cadence) is calculated with that value, a specific value ( For example, if the speed is less than 60 steps per minute, the user's motion state may be detected as a walking state.

Meanwhile, the amount of inertia change in the Z-axis (ground direction) through the motion sensor 138 is continuously measured at a certain level (for example, 2G or more), and when the number of steps per minute (cadence) is calculated with that value, a specific value is obtained. (For example, 80 steps per minute) or more, the user's motion state may be detected as a running state.

In addition, if little change in inertia in the 6th axis occurs through the motion sensor 138 and the pressure of both feet is detected below a certain level through the pressure sensors 121, 122, 123, and 124, the user's operating state is changed to sitting. state can be detected.

Meanwhile, the body member 110 described above may include, for example, a bottom portion 111 and an inclined portion 112.

The bottom portion 111 may be in contact with the F1 region, F2 region, and F3 region of the foot. The sole portion 111 may have an overall flat shape, and a portion may be curved to correspond to the shape of the sole of the foot.

The inclined portion 112 is formed to be inclined with respect to the bottom portion 111 so as to correspond to the inner portion where each of the user's feet faces each other. The inclined portion 112 may be in contact with area F4, which is a relatively concave portion of the sole. The inclination angle of the inclined portion 112 with respect to the bottom portion 111 may be approximately 10 to 20 degrees, but is not limited thereto.

This inclined portion 112 may include an inlet groove 113 into which the battery 134 is installed. For most users, the F4 area generally does not press the smart insole device 100 when walking due to the inner arch of the sole of the foot.

Therefore, when a user walks with the smart insole device 100 according to an embodiment of the present invention installed inside a shoe, the battery 134 is disposed in a portion corresponding to the inner arch of the sole, so that it is used by the user's foot. Since it is hardly pressed, the battery 134 can be prevented from being shocked. Additionally, it is possible to prevent the connection portion between the battery 134 and the main board 131c from being continuously stimulated and short-circuited. In other words, the stability and durability of such a smart insole device 100 can be improved compared to a conventional insole.

Meanwhile, if the above-described bottom portion 111 is described in detail, the bottom portion 111 includes, for example, a first seating portion 111a, a second seating portion 111b, a third seating portion 111c, and a fourth seating portion. It may include a seating portion 111e and a support portion 111d.

A control module 130 may be placed on the first seating portion 111a. For example, the first seating part 111a may be formed to be retracted to a size corresponding to the main board 131c, and the control unit 131a and the storage unit 131b are mounted on the first seating part 111a. The main board 131c can be seated.

The second seating portion 111b is located adjacent to the first seating portion 111a, and the vibration generating member 135 is seated thereon. As described above, the second seating portion 111b is formed at a position corresponding to the F3 region of the foot on the bottom 111 of the body member 110 so that the vibration generating member 135 can transmit vibration to the F3 region of the foot. It can be.

The third seating portion 111c is located adjacent to the first seating portion 111a, and the receiving coil Rx for wireless charging is seated thereon. The third seating portion 111c may be formed at a position corresponding to the F2 region of the foot.

The support portion 111d protrudes from the third seating portion 111c and is positioned to penetrate the center of the receiving coil Rx for wireless charging. The support portion 111d may maintain the initial position of the receiving coil Rx for wireless charging.

The fourth seating portion 111e is located adjacent to the first seating portion 111a, and the motion sensor 138 is seated thereon. To improve the reliability of user movement information, the fourth seating portion 111e may be formed at a position corresponding to the F3 region of the foot.

Referring to FIG. 7, the smart insole device 100 according to an embodiment of the present invention may further include a cover member 140.

The cover member 140 may be coupled to a portion of the body member 110 where the control module 130 is installed. That is, the cover member 140 includes a main board 131c, an antenna 133, a receiving coil for wireless charging (Rx), a battery 134, a vibration generating member 135, and a motion sensor ( After components such as 138) are disposed, they may be attached to one side of the body member 110. For example, an ultrasonic welding method may be used to join the cover member 140 and the body member 110.

This cover member 140 is a control module 130, an antenna 133, a receiving coil for wireless charging (Rx), a battery 134, a vibration generating member 135, a motion sensor 138, etc., applied from the foot. It can be made of a material with high rigidity to prevent damage from pressure. For example, the material of the cover member 140 may be plastic.

Meanwhile, the smart insole device 100 according to an embodiment of the present invention may further include a shock absorbing member 150.

The cushioning member 150 is located between the portion corresponding to the heel of the body member 110 and the cover member 140, and is made of an elastically deformable material. The material of the buffer member 150 for this may be silicon, for example. The shock absorbing member 150 can absorb shock applied from the F3 area, which is the heel of the user's foot, and thus can prevent the cover member 140 and/or the receiving coil (Rx) for wireless charging from being damaged by continuous shock. there is.

To describe the buffer member 150 and the cover member 140 in more detail, the buffer member 150 may include, for example, a base portion 151 and a protrusion 152.

The base portion 151 is accommodated in the cover member 140. The shape of the base portion 151 may be, for example, a plate shape.

The protrusion 152 is formed to protrude from the base portion 151. The protrusion 152 may have a cylindrical shape and may be relatively larger than the receiving coil Rx for wireless charging. This protrusion 152 may be formed integrally with the base portion 151.

And, the cover member 140 includes, for example, a first accommodating part 141, a second accommodating part 142, a third accommodating part 143, a fourth accommodating part 145, and a penetrating part 144. It can be included.

The first receiving portion 141 is formed to be retracted to accommodate at least a portion of the vibration generating member 135.

The second accommodating portion 142 is formed to be retracted to accommodate at least a portion of the control module 130.

The base portion 151 of the buffer member 150 is accommodated in the third receiving portion 143.

The fourth accommodating portion 145 is formed to be retracted to accommodate at least a portion of the motion sensor 138.

By forming the first accommodating part 141, the second accommodating part 142, the third accommodating part 143, and the fourth accommodating part 145, the initial installation position of the internal components is maintained even when an external force is applied. can be maintained stably.

The penetrating portion 144 is formed to penetrate a portion of the third receiving portion 143 so that the protruding portion 152 of the buffering member 150 penetrates. As an example, the method of manufacturing the cover member 140 and the cushioning member 150 includes manufacturing the cushioning member 150 and the cover member 140 using a double injection method after the manufacturing of the cover member 140 is completed. It can be formed integrally. Accordingly, the cover member 140 and the buffer member 150 can be strongly coupled to each other.

Figure 8 is a diagram showing the warning standard pressure value and standard maintenance time according to an embodiment of the present invention, and Figure 9 is a diagram illustrating a method of automatically setting the warning standard pressure value according to an embodiment of the present invention. 10 is a diagram showing a warning message according to an embodiment of the present invention.

In Figure 8, a case in which a total of six pressure sensors are arranged is shown as an example. For convenience of explanation, the three first pressure sensors 121 described above are referred to as the B pressure sensor (Sensor B) and the C pressure sensor ( Sensor C) and D pressure sensor (Sensor D), respectively, and the second pressure sensor 122 was indicated as F pressure sensor (Sensor F). Additionally, the third pressure sensor 123 was indicated as the E pressure sensor (Sensor E), and the fourth pressure sensor 124 was indicated as the A pressure sensor (Sensor A).

The smart insole device 100 may operate in a first mode for setting the above-described warning reference pressure value and reference maintenance time and a second mode for performing pressure monitoring to prevent foot ulcers. At this time, the warning reference pressure value and reference maintenance time set in the first mode can be used as conditions for recognizing the pressure measured from the pressure sensors (Sensor A to Sensor E) as a warning pressure in the second mode.

To this end, the control unit 131a can set the warning reference pressure value and standard maintenance time for each of the plurality of pressure sensors (Sensor A to Sensor E) in the first mode, and the corresponding warning reference pressure value and reference maintenance time are stored in the storage ( 131b).

In addition, specifically, the above-described warning reference pressure value and reference maintenance time may be set separately for each user's operating state. For example, in Figure 8, the warning standard pressure value and standard maintenance time are set when the user's motion state is walking, and the warning standard pressure value and standard maintenance time are set when the user's motion state is in the standing, running, and sitting state. The time can be set individually.

For example, when a standard setting request is transmitted from the user terminal, the control unit 131a may enter the first mode to set the warning standard pressure value and standard maintenance time in response.

Afterwards, the control unit 131a can automatically set a warning reference pressure value for each pressure sensor (Sensor A to Sensor E) using the pressure generated when the user performs each operation state.

Specifically, the control unit 131a transmits a request message to stand in place to the user terminal when entering the first setting period, and uses the pressure applied to a plurality of pressure sensors (Sensor A to Sensor E) during the first setting period to Automatically sets the warning reference pressure value for each pressure sensor (Sensor A to Sensor E) in the standing state, transmits a walking request message to the user terminal when entering the second setting period, and sends a walking request message to the user terminal during the second setting period. Using the pressure applied to the sensors (Sensor A to Sensor E), the warning standard pressure value for each pressure sensor (Sensor A to Sensor E) can be automatically set while the user is walking. In addition, when entering the third set period, a run request message is transmitted to the user terminal, and the pressure applied to a plurality of pressure sensors (Sensor A to Sensor E) during the third set period is used to detect the pressure sensor in the user's run state. The warning standard pressure value is automatically set for each (Sensor A to Sensor E), and when entering the fourth setting period, a sit-down request message is sent to the user terminal, and a plurality of pressure sensors (Sensor A to Sensor E) are connected during the fourth setting period. By using the pressure applied, the warning standard pressure value for each pressure sensor (Sensor A to Sensor E) can be automatically set when the user is sitting.

For example, as shown in FIG. 9, the control unit 131a may transmit a message requesting the user terminal to perform a specific operation state (for example, a walking state), and the user may perform a preset operation according to the message. The corresponding action state can be performed during the period. The control unit 131a can collect the pressure generated from the pressure sensors (Sensor A to Sensor E) during the corresponding period and use it to set a warning reference pressure value.

For example, the warning reference pressure value may be initially set to a specific default value for each pressure sensor (Sensor A to Sensor E), and if a warning pressure exceeding the initially set warning reference pressure value is generated in a specific pressure sensor while performing the first mode, In this case, the warning pressure can be automatically set to the warning reference pressure value of the specific pressure sensor.

At this time, the warning pressure may be calculated as the average value of pressure values generated during a preset period in the first mode.

In addition, the control unit 131a monitors the user's operating state based on the movement information measured by the motion sensor 138 and the pressure information measured by the pressure sensors (Sensor A to Sensor E) during each setting period of the first mode. By detecting, if the user's operating state is not required in each set period, vibration feedback through the vibration generating member 135 can be provided to the user. Through this, it is possible to prevent setting errors in the warning reference pressure value caused by the user performing the operating state incorrectly.

Specifically, the control unit 131a provides vibration feedback to the user through the vibration generating member 135 when the user's operating state is not the standing state in the first set period, and the user's operating state is not in the standing state in the second set period. When the user is not in a walking state, vibration feedback can be provided to the user through the vibration generating member 135. In addition, if the user's operating state is not a running state in the third setting period, vibration feedback is provided to the user through the vibration generating member 135, and if the user's operating state is not a sitting state in the fourth setting period, vibration feedback is provided to the user. Vibration feedback can be provided to the user through the generating member 135.

The standard holding time in the first mode is also similar to the warning standard pressure value, and can be automatically set for each pressure sensor (Sensor A to Sensor E) by dividing it according to the user's operating state.

For example, the reference maintenance time may be initially set to a specific default value for each pressure sensor (Sensor A to Sensor E), and the reference maintenance time may be initially set if the warning pressure exceeds the warning reference pressure value in a specific pressure sensor while performing the first mode. If an abnormality occurs, the generation time of the warning pressure can be automatically set to the standard maintenance time of the specific pressure sensor.

Referring to FIG. 10, in the second mode, the control unit 131a detects a warning pressure greater than the warning reference pressure value in at least one specific pressure sensor among the plurality of pressure sensors (Sensor A to Sensor E) for more than the standard maintenance time. , a warning message can be sent to the user terminal.

At this time, the warning message may display the current operating state, warning pressure generation location, warning pressure measurement value, warning pressure maintenance time, and warning pressure occurrence frequency.

For example, the control unit 131a determines that in the second mode, the pressure measured by the A pressure sensor (Sensor A) is greater than or equal to the warning standard pressure value (PL1), and the measured pressure greater than or equal to the warning standard pressure value (PL1) is maintained as the standard. If it is maintained for more than time (TL1), the measured pressure can be recognized as a warning pressure. Accordingly, the control unit 131a may transmit a warning message to the user terminal notifying the user that warning pressure has occurred.

In addition, the control unit 131a detects the user's operating state based on the movement information measured by the motion sensor 138 and the pressure information measured by the pressure sensors (Sensor A to Sensor E) in the second mode. The warning reference pressure value and reference holding time for each pressure sensor (Sensor A to Sensor E) corresponding to the operating state of the user are read from the storage unit 131b and at least one of the plurality of pressure sensors (Sensor A to Sensor E) is read. If a warning pressure higher than the warning standard pressure value is detected by a specific pressure sensor for longer than the standard maintenance time, a warning message can be sent to the user terminal.

Meanwhile, the control unit 131a provides vibration feedback to the user through the vibration generating member 135 when warning pressure occurs, thereby providing feedback on the occurrence of warning pressure to the user without interworking with the user terminal.

For example, in the second mode, the control unit 131a vibrates when a warning pressure higher than the warning reference pressure value is detected in at least one specific pressure sensor among the plurality of pressure sensors (Sensor A to Sensor E) for more than the standard maintenance time. Vibration feedback can be provided to the user through the generating member 135.

At this time, the characteristics of the vibration feedback may be changed in response to at least one of the number of pressure sensors generating warning pressure, the size of the warning pressure, and the maintenance period of the warning pressure.

Specifically, the control unit 131a may change the pattern of vibration feedback in response to the number of specific pressure sensors that generate warning pressure in the second mode. For example, as the number of pressure sensors generating warning pressure increases, the unit vibration number of vibration feedback can be increased.

Additionally, the control unit 131a may change the intensity of the vibration feedback in response to the magnitude of the warning pressure detected by a specific pressure sensor. For example, as the magnitude of the warning pressure increases, the intensity of the vibration feedback can be increased.

The control unit 131a may change the time for providing vibration feedback in response to the maintenance period of the warning pressure detected by a specific pressure sensor. For example, if the warning pressure maintenance period exceeds a preset time, the vibration feedback provision time can be set longer than before.
