Description

Rehabilitation device and dysphagia rehabilitation system using the same

Embodiments of the invention relate to dysphagia rehabilitation techniques.

Recently, as the elderly population increases due to aging, the severity of dysphagia (swallowing disorder) is increasing. Dysphagia refers to difficulties in moving food from the mouth to the stomach. Since dysphagia interferes with intake of nutrients and water and takes away the pleasure of eating, the quality of life of a person with dysphagia is inevitably reduced.

Existing dysphagia rehabilitation systems are divided into an analog method and a digital method. The analog method has a disadvantage in that it is difficult to check whether a patient is undergoing rehabilitation or not, and it is difficult to check the degree of muscle rehabilitation. In addition, the digital method can check the pressure of the patient's tongue, but it is only a simple repetitive movement of the tongue, and the air valve or cable must be held in the patient's mouth, causing discomfort to the patient when used for a long time.

1 is a diagram showing the configuration of a dysphagia rehabilitation system according to an embodiment of the present invention.

Referring to FIG. 1 , a dysphagia rehabilitation system 100 may include a rehabilitation device 102 and a game device 104 . The rehabilitation device 102 and the game device 104 are communicatively connected via a communication network 150 .

In the disclosed embodiment, communication network 150 may be the Internet, one or more local area networks, wide area networks, cellular networks, mobile networks, other types of networks, or such networks. may include a combination of

The rehabilitation device 102 is a device for rehabilitation of the swallowing function of a user with dysphagia. The rehabilitation device 102 is provided to be installed in the user's mouth. Since the rehabilitation device 102 is mounted inside the user's mouth, a housing constituting the exterior of the rehabilitation device 102 may be made of a biocompatible material (eg, silicone or polymer). The rehabilitation device 102 may be provided to be mounted on the roof of the mouth inside the user's mouth.

2 is a diagram showing the configuration of a rehabilitation device 102 according to an embodiment of the present invention. Referring to FIG. 2 , the rehabilitation device 102 may include a sensor array module 111 , a signal measurement module 113 , a communication module 115 , and a battery module 117 .

The sensor array module 111 may be provided to sense pressure by the user's tongue. That is, when the rehabilitation device 102 is mounted on the roof of the user's mouth, the sensor array module 111 may be provided to detect pressure pressed by the user's tongue. To this end, the sensor array module 111 may be formed in the form of a flat plate having a certain area.

The sensor array module 111 may include a plurality of sensors so as to distinguish a position where the user's tongue is pressed. That is, the sensor array module 111 may include a plurality of sensors 111a arranged horizontally and vertically as shown in FIG. 3 . The plurality of sensors 111a may be electrically connected to the signal measurement module 113 to form separate channels.

Each sensor 111a may be provided to generate energy according to friction with the user's tongue. In an exemplary embodiment, each sensor 111a may consist of a triboelectric energy harvester.

The electrode layer 121 is provided to have conductivity. The electrode layer 121 may be electrically connected to ground (ground). In an exemplary embodiment, the electrode layer 121 may include a gel-type electrode in which nanowires or carbon nanotubes are inserted.

The electrode layer 121 may be provided by inserting conductive nanowires or carbon nanotubes into a viscoelastic material. As the viscoelastic material, poly dimethylsiloxane (PDMS) may be used, but is not limited thereto. Since the electrode layer 121 is made of a gel type of viscoelastic material, when the user's tongue contacts the first dielectric layer 123, it is deformed together with the first dielectric layer 123 according to the pressure applied by the user's tongue, Since it covers the tongue of the user, the contact area between the first dielectric layer 123 and the tongue of the user is widened. As a result, it is possible to increase the amount of triboelectric charge energy.

In addition, as the electrode layer 121 is formed of a gel-type electrode into which nanowires or carbon nanotubes are inserted, discomfort to the user can be minimized. That is, the rehabilitation device 102 is installed in the user's mouth, and when a general thin film or sheet type electrode layer is used, the flexible property is small, and the feeling of wearing is reduced, causing the user to feel uncomfortable.

The first dielectric layer 123 may be made of a non-conductive polymer. For example, the first dielectric layer 123 may be made of polytetrafluoroethylene (PTFE). Since polytetrafluoroethylene (PTFE) contains fluorine, which is a strongly negatively charged element, it is possible to increase the amount of frictional electrification energy by forming many negative charges by friction when in contact with the user's tongue.

The second dielectric layer 125 may be formed under the electrode layer 121 . The second dielectric layer 125 may be made of a non-conductive polymer. For example, the second dielectric layer 125 may be made of poly dimethylsiloxane (PDMS). The second dielectric layer 125 may be provided to face the roof of the user's mouth. Here, since PDMS (poly dimethylsiloxane) has viscoelasticity, it can be easily attached to the roof of the user's mouth.

Referring to FIG. 5 , each sensor 111a of the sensor array module 111 is mounted in a state where the first dielectric layer 123 faces the user's tongue and the second dielectric layer 125 faces the roof of the user's mouth. It can be. Here, when the user's tongue is separated from the first dielectric layer 123, it is in an initial state without any surface charge (Fig. 5(a)).

When the user's tongue contacts the first dielectric layer 123, the surface of the first dielectric layer 123 is negatively charged due to friction between the user's tongue and the first dielectric layer 123 (FIG. 5(b) ). Then, electrons of the electrode layer 121 move to the ground to maintain an electrical equilibrium state, and the electrode layer 121 is positively charged (FIG. 5(c)).

And, when the user's tongue is separated from the first dielectric layer 123, the amount of negative charge on the surface of the first dielectric layer 123 is weakened (FIG. 5(d)), and grounded to maintain electrical equilibrium. At , electrons move to the electrode layer 121, and the positive charge of the electrode layer 121 is reduced (FIG. 5(e)). When the user's tongue is completely separated from the first dielectric layer 123 and spaced apart, the initial state is restored as shown in FIG. 5(a).

When the user's tongue repeatedly contacts and separates from the first dielectric layer 123, an alternating current is generated due to the movement of electrons, as seen above, and thus energy is generated.

Bar, The sensor array module 111 may check a channel where the user's tongue is detected.

The signal measuring module 113 may calculate the pressure intensity of the tongue in the channel where the user's tongue is detected.

Also, the signal measurement module 113 may calculate a contact duration of the user's tongue in a channel where the tongue is detected.

The signal measurement module 113 may generate a user interface signal including at least one of channel information of the user's tongue detected, tongue pressure intensity, and tongue contact duration. The signal measurement module 113 may generate a user interface signal whenever a user applies pressure to the sensor array module 111 by moving his/her tongue.

Meanwhile, when triboelectric energy is generated from the plurality of sensors 111a at the same time, the signal measurement module 113 compares the triboelectric energy generated from the plurality of sensors 111a, and the sensor 111a has the largest amount of triboelectric energy. ) to generate user interface signals. That is, when the user's tongue contacts several sensors 111a at the same time, the signal measurement module 113 determines the sensor 111a having the largest amount of triboelectric energy as the sensor 111a selected by the user, and interfaces with the user interface. signal can be generated.

In addition, the signal measurement module 113 may determine that a touch has been missed (ie, a touch has been made by mistake) when the frictional electrification energy generated from the sensor 111a in contact with the user's tongue is less than a predetermined threshold energy. In this case, the signal measurement module 113 may not generate a user interface signal.

The communication module 115 may operate with energy generated by the sensor array module 111 . The communication module 115 may communicate with the game device 104 . In an exemplary embodiment, communication module 115 may be a Bluetooth communication module.

The battery module 117 may include a battery and a charging circuit for charging the battery with power generated by the sensor array module 111 . The battery module 117 may supply power to the signal measurement module 113 and the communication module 115 .
