Some people are born with disabilities, but all of them become physically weak as they get older, which causes difficulties in their behavior. Or even if you injure your leg due to an unexpected accident, you will not be able to move easily.

Meanwhile, in recent years, due to the increase of the elderly population and the reinforcement of welfare policies, wheelchairs for the disabled, the elderly, and patients are widely spreading. However, since wheelchairs are for people who can hardly move on their own, people with some discomfort in gait do not use a wheelchair as much as possible, and it is desirable to move on their own in terms of health.

Thus, people with discomfort in gait usually use a cane to balance their body when moving. However, most canes have a structure in which a support part in contact with the ground is formed at the lower end of a long, straight body, and a handle is formed at the upper end of the body.For those with limited mobility, these general canes are used to stably maintain body balance. It was insufficient, and it was able to secure a sense of stability when walking by balancing the elderly, but there was a problem in that it was not efficient in its function, such as being limited only to walking assistance.

As such, it has been reported that, through various studies, if a certain stimulus is applied to the body of the elderly or patients with brain injury who are inferior in physical activity, the cognitive ability is improved due to the bio-self-control effect. There is no development of a device that gives stimulation in real time.

A plurality of measuring electrodes can be coupled along the part of the body moving along the joint and in proximity to the patient's spine, which measure action potentials along patient muscle groups during controlled patient joint movements, and measure the measured action potentials. As the technology for "a device configured and arranged to transmit to a dynamic surface muscle activity test ("sEMG") module" was disclosed, in the conventional case, research and development on large equipment that measures and examines the muscle activity of the body has been conducted in various ways. However, there is a problem that research and development of a small device that can be worn by the elderly or patients directly and directly apply constant vibration or electrical stimulation to the body as needed is hardly in progress.

The control module 230 constituting the mobile device of the wearable control means 200 extracts a dedicated application previously stored in the storage module 240, and the measurement data, which is the dynamic signal, is inputted from the input unit 210. By applying data and user basic information previously registered by the user to the dedicated application, a behavior for dynamic change is predicted, and stimulus information corresponding to the predicted behavior is extracted. Here, the dedicated application is an application registered in advance to extract stimulus information based on user's dynamic change information and user basic information. These dedicated applications can be downloaded from a server that supports dedicated applications through a network and stored and used, or downloaded through a separate memory device and stored and used. In addition, the basic information of the user is information directly inputted by the user through the operation unit and reference data measured during normal walking, and is measured during normal walking through the user's age, gender, weight, suspected symptoms and wearable detection means (100).

And, as shown in Figure 2, the normal signal generator (231-1) included in the determination module (231) constituting the wearable control means (100) is further included, and generated by the wearable detection means (100). If the measured data value falls within the set range, a normal signal is generated. That is, the wearable detection means 100 measures the pressure applied by the user's foot, the force, and the inclination, displacement, and orientation of the user's center of gravity or lower limbs, and When dynamic signals such as inclination, displacement, and orientation are generated, and each of these dynamic signal values are within a set range in which a user can live daily life, the normal signal generator 231-1 generates a normal signal. .

In addition, as shown in FIG. 2, an abnormal signal generator 231-2 included in the determination module 231 constituting the wearable control means 200 is included to generate an abnormal signal when the dynamic signal is out of a set range. Occurs. That is, the abnormal signal generator (231-2), the wearable detection means (100) measures the pressure applied to the user's foot, the force, and the inclination, displacement and orientation of the user's center of gravity or lower limb, and the dynamic signal value is determined by the user. When it is out of the set range in which daily life can be carried out, an abnormal signal is generated indicating that it is not a normal situation. For example, at the moment when the user is walking on the road and suddenly becomes dizzy and tries to fall, the wearable detection means 100 measures the abnormal body imbalance of the user, and the abnormal signal generator 231 of the wearable control means 200 -2) detects and generates an abnormal signal.

When an abnormal signal is generated from the abnormal signal generating unit 231-2, a warning alarm for recognizing that the user is in an emergency may be repeatedly generated, and in addition, at least one selected from among the lower limb muscles important for maintaining the balance of the body A signal is provided to the wearable stimulation means 300 for applying low-frequency current or vibration to stimulate the muscles of the attached area to induce a normal balance.

The wearable stimulation means 300 is a device that generates a low-frequency current, and is provided in any one or more selected from among the lower limb muscles that are important for maintaining the balance of the body, so that the measurement data of the wearable detection means 100 provided in the user's lower limb The user's muscle stimulation data corresponding to the reference data on the user's body change set in advance with respect to the data values for measuring the inclination, displacement, and orientation of the body are set and stored in the wearable control means 200 so that the user is about to fall. In this case, it is determined whether the muscles of which leg must be stimulated to return to normal body balance, and the signal is transmitted to the wearable stimulation means 300 by the stimulation information output unit 235.

Between the wearable detection means 100 and the wearable control means 200, and between the wearable control means 200 and the wearable stimulation means 300, signals are transmitted and received through a communication module, respectively, and the communication module is wirelessly connected, and the The smartphone included in the wearable control means 200 transmits various data information (measurement data, normal signals, abnormal signals, etc.) measured by the wearable detection means 100 to the smartphone to analyze the user's body balance. To be. These communication modules are Bluetooth 4.0 version or higher. In addition, mobile phones through short-range wireless communication such as ZigBee, infrared, UWB (Ultra Wide Band), wireless LAN, and NFC (Near Field Communication). Of course, it can also be transmitted to (200).

The smartphone of the wearable control means 200 that communicates with the wearable detection means 100 of the present invention is equipped with a dedicated application as described above, and the dedicated application includes measurement data, normal signals and signals received from the wearable detection means 100. The abnormal signal can be converted into numerical information that can be visually confirmed, and a phone number for the user's emergency contact E1 or emergency center E2 can be input.

Such a dedicated application system, when receiving the abnormal signal generated by the abnormal signal generator 231-2 of the wearable control means 200, the wearable control means that normal body recovery is impossible by the wearable stimulation means 300 ( When the abnormal signal generator (231-2) of 200) determines, that is, by the wearable stimulation means 300, the measurement data deviating from the normal body reference data of the user is set in time due to low-frequency stimulation. If it occurs continuously within the user, it is sent by text to the entered emergency contact that the user is in an emergency, and the emergency contact is a family member or friend. It can be a relative, etc.

In addition, the dedicated application comprehensively analyzes the above-described normal and abnormal signals.

In addition, the reference data that is a reference to the normal signal of the user is based on information and determination of data measured by the wearable detection means 100 in a stable walking state while the user is walking, and the reference data during walking of the user is wearable. It is stored in the normal signal generator 231-1 of the control means 200, or is stored in a database of a smartphone included in the wearable control means 200 or in an external server (not shown), and transmitted to a dedicated app for display.

In addition, the measurement data that generates an abnormal signal when the user walks is received by the smartphone of the wearable control means 200 or an external server, and is stored in the normal signal generator 231-1 of the wearable control means 200. The abnormal signal generator (231-2) receiving the data determines whether or not the abnormal signal is generated by mutually analyzing the measured data and the reference data. At this time, if the user's walking is determined as an abnormal signal, the abnormal signal generator (231-) 2) transmits a stimulation signal to the wearable stimulation means 300 by the stimulation information output unit 235 to operate the wearable stimulation means 300.

The wearable stimulation means 300 may be attached to the surface of a muscle that moves the skeleton constituting the user's lower limbs or implanted into the muscle, and is not limited to the user's low-frequency generating device by being attached to the muscle. Any device that performs electrical or physical generation corresponding to the stimulus may be included.

In addition, the wearable stimulation means 300 is attached to the lower extremity, and is included with the wearable detection means 100 for measuring the dynamic change of the user, that is, if it is one attachment pad, the wearable detection means 100 is provided on one side of the attachment pad. ) And the wearable stimulation means 300 may be included on the other side, or may be attached to contact the skin to activate the muscles of the body separately from the wearable detection means 100.

In addition, the muscle activity information extraction unit 234 for extracting muscle activity information on the movement of the lower limb muscles corresponding to the behavior predicted by the measurement data on the foot pressure of the wearable detection means 100 described above and the extracted muscle activity information Unlike a system in which the wearable stimulation means 300 is operated by the stimulation information output unit 235 that generates the stimulation time and intensity as stimulation information and outputs the stimulation time and intensity to the short-range wireless communication module 260, The following control is further included to stimulate the direct stimulation means by calculating the foot pressure measurement data and the dynamic change measurement data of the wearable detection means 100.

As shown in Fig. 2, when an abnormal signal is generated in the abnormal signal generating unit 231-2, when a stimulation signal is commanded by the wearable stimulation means 300, the stimulation means attached to a part of the user's body is operated. Normal medical muscle activation exercise that determines how much stimulation intensity is determined while performing, i.e., a muscle activity generating unit in which activity data that sets the corresponding medical muscle activity corresponding to the change in the direction of the user's fall and the skeleton ( 231-3) is further included in the wearable control means 200 to determine active data suitable for the user's body dynamic change measurement data, which is a criterion for determining the abnormal signal, and sends a stimulation signal to the wearable stimulation means 300 to stimulate the wearable. The means 300 is to be operated.

When the stimulation signal is generated by the activation data stored in the muscle activity generator (231-3), the stimulation signal determines the operating position of the stimulation means located at which part of the user, if the wearable stimulation means 300 is a low-frequency generator. In this case, the positioning of the stimulation means is located at the corresponding muscle part of the user determined by preset medical activity data, and the stimulation signal including the low frequency wavelength, intensity and time of the low frequency generator is transmitted.

In this way, when the body change information of the user's dynamic change is measured by the at least one wearable detection means 100, a normal signal constituting the determination module 231 of the smartphone included in the wearable control means 200 is generated. The unit 231-1 or the abnormal signal generator 231-2 determines whether the user's body dynamic change is normal or ideal, and generates a normal or abnormal signal for the determined dynamic change. When is generated, the activation data suitable for the measurement data for the abnormal signal is determined from the activation data of the wearable control means 200 or the muscle activity generator 231-3 included in the determination module 231, and the stimulation signal is stimulated by the wearable. It is transmitted to the means 300 and operated to activate the user's muscles to induce normal body changes. The determination criterion of the determination module 231 may be determined according to the mode of the dedicated application system selected by the user.

For example, when specific muscle activity information according to an abnormal signal is detected while walking by activating the walking mode of the dedicated application, the measured value of the user's dynamic change determined as described above is determined by the wearable control means 200 or the wearable control means. Depending on whether the reference data stored in the storage module 240 of 200 correspond to each other, that is, whether the measured measured value is within the range of dynamic change information of normal walking, the user's abnormality is caused by the determination module 231. Whether or not a signal is generated can be determined.
