Description

biostimulation device

[0001] The present disclosure relates to a biostimulation device, and more particularly, to a biostimulation device that stimulates a specific area using current flowing through a plurality of electrodes.

[0002] Research into treating neurological and psychiatric disorders is actively underway, and electroceutical technology, which utilizes brain stimulation to activate or suppress brain activity through electrical stimulation, is gaining attention. Representative brain stimulation treatments include invasive treatments, which directly stimulate the brain through implanted electrodes, and noninvasive treatments, which externally stimulate the brain using magnets, electricity, or ultrasound. Invasive treatments carry the risk of side effects or complications following surgery to implant electrodes, and the burden on patients is significant, leading to active research into noninvasive treatments.

Here, each of the first frequency and the second frequency may correspond to a high frequency that does not stimulate a living body. The difference between the first frequency and the second frequency may correspond to a low frequency that stimulates a living body.

The control unit (150) can control a driving unit corresponding to an electrode included in the second group among the plurality of driving units (140) so that an AC current having a second frequency flows to the electrode included in the second group.

[0034] Referring to FIG. 2, a plurality of electrodes (145) may be arranged in the housing (101) of the bio-stimulation device (100). The plurality of electrodes (145) may be arranged in the housing (101) so as to be spaced apart from each other. For example, the plurality of electrodes (145) may be arranged so as to be spaced apart from each other by a preset distance. When a user wears the bio-stimulation device (100), the plurality of electrodes (145) arranged in the housing (101) may be positioned adjacent to the user's body.

[0035] Each of the plurality of electrodes (145) may be electrically connected to a corresponding driving unit among the plurality of driving units (140). Current output from the plurality of driving units (140) may flow through the plurality of electrodes (145). The amplitude and / or phase of the alternating current flowing through the plurality of electrodes (145) may be different from each other.

[0036] Meanwhile, the total sum of the alternating currents having the first frequency flowing through the electrodes included in the first group among the plurality of electrodes (145) may be 0. In addition, the total sum of the alternating currents having the second frequency flowing through the electrodes included in the second group among the plurality of electrodes (145) may also be 0.

[0037] Referring to FIG. 3, a driving unit (140) according to one embodiment of the present disclosure may include a signal generator (Vf). The signal generator (Vf) may generate a signal having a predetermined frequency. The signal generated by the signal generator (Vf) may correspond to a voltage.

[0041]

[0042] Here, N represents the number of bits of the signal used to control the voltage divider (Rp), and D can correspond to the resistance value of the variable resistor included in the voltage divider (Rp).

[0043] The driving unit (140) may further include at least one buffer composed of an operational amplifier, a load (RL), etc.

[0044] FIGS. 4 to 8 are drawings for reference in the description of a biostimulation device according to one embodiment of the present disclosure.

[0045] Hereinafter, directions are defined based on the rectangular coordinate system. In the rectangular coordinate system, the x-axis direction can be defined as the left-right direction. At this time, the direction toward +x with respect to the origin can mean the right direction, and the direction toward -x can mean the left direction. In addition, the y-axis direction can be defined as the front-back direction. At this time, the direction toward +y with respect to the origin can mean the front direction, and the direction toward -y can mean the rear direction. In addition, the z-axis direction can be defined as the up-down direction. At this time, the direction toward +z with respect to the origin can mean the upward direction, and the direction toward -z can mean the downward direction.

[0046] Referring to FIG. 4, a bio-stimulation device (100a) according to one embodiment of the present disclosure may include a plurality of electrodes (145). At this time, the plurality of electrodes (145) may be arranged on the same plane. The plurality of electrodes (145) may be arranged on a predetermined plane that is parallel to the x-axis and y-axis and perpendicular to the z-axis.

[0047] The housing (101a) of the biostimulation device (100a) may be formed to have a circular band shape. A plurality of electrodes (145) may be arranged along the perimeter of the housing (101a) at a predetermined distance from each other. In the present disclosure, 32 electrodes are arranged in the biostimulation device (100a) as an example, but the present invention is not limited thereto.

[0048] The user's body can be positioned in the area (105) surrounded by the inner surface of the housing (101a). That is, when the user wears the biostimulation device (100a), the housing (101a), which is shaped like a circular band, can surround the user's body. At this time, a plurality of electrodes (145) can be arranged to form a circular band around the user's body.

[0049] When two AC currents having different frequencies flow through a plurality of electrodes (145), a beat phenomenon may occur inside an area corresponding to the plurality of electrodes (145) (hereinafter, referred to as a target area). At this time, a low-frequency envelope may be generated due to the beat phenomenon caused by reinforcement and / or cancellation of electric fields corresponding to the two AC currents. The frequency of the low-frequency envelope generated due to the beat phenomenon may correspond to the frequency difference between the two AC currents flowing through the plurality of electrodes (145). For example, when the frequency difference between the two AC currents flowing through the plurality of electrodes (145) is 20 Hz, the frequency of the low-frequency envelope may be 20 Hz. Therefore, when a low-frequency envelope due to the beat phenomenon is generated at a specific location in the target area, the specific location may be stimulated.

[0050] The size of the area stimulated by the low-frequency envelope (hereinafter, the stimulation range) can correspond to the number of electrodes through which an AC current flows. Referring to Fig. 5, comparing the cases where the number of electrodes through which an AC current flows is 4 (501), 16 (502), and 32 (503), it can be confirmed that the stimulation range decreases as the number of electrodes through which an AC current flows increases. In other words, as the number of electrodes used to generate the low-frequency envelope increases, more detailed stimulation of a specific location can be achieved.

[0051] The location stimulated by the low-frequency envelope (hereinafter, "stimulation location") may correspond to the location of electrodes included in each of the multiple groups and / or the intensity of the alternating current flowing through each electrode. In this case, the stimulation location may correspond to one of various locations constituting the target area.

[0052] The control unit (150) can set the stimulation location and / or stimulation range. For example, the control unit (150) can set the stimulation location and / or stimulation range based on a command received through the input unit (120).

[0053] The control unit (150) can determine the frequency, magnitude, and / or phase of the alternating current flowing to each of the plurality of electrodes (145) based on the set stimulation position and / or stimulation range. For example, the control unit (150) can determine the frequency, magnitude, and / or phase of the alternating current flowing to each of the plurality of electrodes (145) based on a table corresponding to the stimulation position and / or stimulation range stored in the memory (110).

[0054] The control unit (150) may classify some of the plurality of electrodes (145) into a first group corresponding to a first frequency and the other parts into a second group corresponding to a second frequency, based on the set stimulation position and / or stimulation range. At this time, the control unit (150) may determine the magnitude and / or phase of an alternating current having a first frequency flowing through each of the electrodes included in the first group, and may determine the magnitude and / or phase of an alternating current having a second frequency flowing through each of the electrodes included in the second group.

[0055] Regarding the alternating current flowing through the plurality of electrodes (145), a description will be given with reference to FIGS. 6 to 8. With respect to the description of FIGS. 6 to 8, a biostimulation device (100a) including 16 electrodes will be described as an example. Meanwhile, in FIGS. 6 to 8, the stimulation position is expressed as a coordinate on the xy plane, and an example will be described in which the coordinate corresponding to the center of the target area is (0,0).

[0056] Referring to Fig. 6, when the stimulation position is (0,0), eight electrodes arranged in series, corresponding to half of the plurality of electrodes (145) included in the biostimulation device (100a), may be included in the first group (610). In addition, eight electrodes corresponding to the remaining half of the plurality of electrodes (146) may be included in the second group (620).

[0057] The control unit (150) can determine the magnitude and / or phase of an alternating current having a first frequency flowing through each of the electrodes included in the first group (610). At this time, the total sum of the currents flowing through the electrodes included in the first group (610) may be 0.

[0058] The control unit (150) can determine the magnitude and / or phase of an alternating current having a second frequency flowing through each of the electrodes included in the second group (620). At this time, the total sum of the currents flowing through the electrodes included in the second group (620) may also be 0.

[0059] Referring to Fig. 7, when the stimulation position is (0,5), seven electrodes arranged in succession may be included in the first group (710), and the remaining nine electrodes may be included in the second group (720). At this time, the stimulation position (0,5) may be adjacent to the second group (720) compared to the first group (710).

[0060] The control unit (150) can determine the magnitude and / or phase of an alternating current having a first frequency flowing through each of the electrodes included in the first group (710). At this time, the total sum of the currents flowing through the electrodes included in the first group (710) may be 0.

[0061] The control unit (150) can determine the magnitude and / or phase of an alternating current having a second frequency flowing through each of the electrodes included in the second group (720). At this time, the total sum of the currents flowing through the electrodes included in the second group (720) may also be 0.

[0062] Referring to Fig. 8, when the stimulation location is (0,10), 11 electrodes arranged in succession may be included in the first group (810), and the remaining 5 electrodes may be included in the second group (820). At this time, the stimulation location (0,10) may be adjacent to the second group (820) compared to the first group (810).

[0063] The control unit (150) can determine the magnitude and / or phase of an alternating current having a first frequency flowing through each of the electrodes included in the first group (810). At this time, the total sum of the currents flowing through the electrodes included in the first group (810) may be 0.

[0064] The control unit (150) can determine the magnitude and / or phase of an alternating current having a second frequency flowing through each of the electrodes included in the second group (820). At this time, the total sum of the currents flowing through the electrodes included in the second group (820) may also be 0.

[0065] The number of electrodes included in each of the first and second groups may be odd or even, depending on the stimulation location. Furthermore, as the stimulation location moves away from the center of the target area, the difference between the number of electrodes included in the first group and the number of electrodes included in the second group may increase. Meanwhile, while FIGS. 6 to 8 illustrate examples of consecutively arranged electrodes included in each group, the present invention is not limited thereto.

[0066] FIGS. 9 to 12 are drawings that are referenced in the description of a biostimulation device according to another embodiment of the present disclosure. Any details that overlap with those described in FIGS. 4 to 8 will be omitted for detailed description.

At this time, the plurality of electrodes (145) may be arranged on a plurality of planes. The plurality of electrodes (145) may be arranged on a plurality of planes that are parallel to the x-axis and the y-axis and perpendicular to the z-axis. For example, 12 electrodes (145) may be arranged on a plane where the z-axis value is 0, 8 electrodes (145) may be arranged on a plane where the z-axis value is a, 8 electrodes (145) may be arranged on a plane where the z-axis value is b, and 4 electrodes (145) may be arranged on a plane where the z-axis value is c.

[0068] The housing (101b) of the biostimulation device (100b) may be formed to have a hemispherical shape. A plurality of electrodes (145) may be arranged along the periphery of the housing (101b) at a predetermined distance from each other. In the present disclosure, 32 electrodes are arranged in the biostimulation device (100b) as an example, but the present invention is not limited thereto.

[0069] The user's body can be positioned in the area (105) surrounded by the inner surface of the housing (101b). That is, when the user wears the biostimulation device (100b), the hemispherical housing (101b) can surround the user's body. In this case, a plurality of electrodes (145) can be arranged to form a three-dimensional hemisphere around the user's body.

[0070] Referring to Figure 10, comparing the case where the number of electrodes through which an AC current flows is 4 (1001) with the case where the number of electrodes through which an AC current flows is 32 (1202), it can be confirmed that the stimulation range decreases as the number of electrodes through which an AC current flows increases. In other words, as the number of electrodes used to generate a low-frequency envelope increases, more detailed stimulation of a specific location can be achieved.

[0071] Regarding the alternating current flowing through the plurality of electrodes (145), a description will be given with reference to FIGS. 11 and 12. With respect to the description of FIGS. 11 and 12, a biostimulation device (100b) including 32 electrodes will be described as an example.

[0073] The control unit (150) can determine the magnitude and / or phase of an alternating current having a first frequency flowing through each of the electrodes included in the first group. At this time, the total sum of the currents flowing through the electrodes included in the first group may be 0.

[0074] The control unit (150) can determine the magnitude and / or phase of an alternating current having a second frequency flowing through each of the electrodes included in the second group. At this time, the total sum of the currents flowing through the electrodes included in the second group may also be 0.

[0075] Referring to Fig. 12, when the stimulation position is (0,5,5), some of the electrodes (145) included in the biostimulation device (100b) may be included in the first group, and the remaining some of the electrodes may be included in the second group. At this time, the electrodes included in the first group in Fig. 12 may be different from the electrodes included in the first group in Fig. 11.

[0076] Meanwhile, the total sum of the currents flowing through the electrodes included in the first group and the total sum of the currents flowing through the electrodes included in the second group can both be 0.
