Description

  The present invention relates to a cervical electrical stimulation apparatus for applying electrical stimulation to a cervical part of a living body, and in particular, an electrical stimulation apparatus capable of preventing positional displacement of electrodes due to a user's body movement or the like. It is about.

  The purpose is to improve or improve the quality of life by treating or supporting patients with sequelae whose physical function remains impaired due to cerebrovascular disorders such as cerebral hemorrhage or cerebral infarction. Various medical devices are known. Specifically, for patients with dysphagia that develops due to, for example, cerebrovascular disorders, and in which one of a complex series of actions involving swallowing food through the oral cavity, pharynx and esophagus is impaired, There are cases where an electrical stimulation device capable of applying electrical stimulation to a laryngeal elevation muscle group in a patient's neck is used (for example, Patent Documents 1 and 2). And it is known that there is a possibility of restoring the swallowing function of the patient by assisting the swallowing operation of the patient and promoting the swallowing reflex by the electrical stimulation. In addition, a treatment method for electrically stimulating the cervical vagus nerve is known as a treatment method for hypertension, and a technique for enabling the electrical stimulation to be stably performed for a long time is required.

JP 2010-530331 A JP 2007-151747 A

  By the way, treatment or training (hereinafter referred to as “treatment etc.”) for applying electrical stimulation to the patient's neck using the electrical stimulation device as described in Patent Documents 1 and 2 above to restore the patient's swallowing function. In the case of performing such treatment, it is necessary to transmit the electrical stimulation generated by the device to the neck sufficiently effectively. In the treatment using the electrical stimulation device, for example, when the treatment is performed using a treatment protocol that performs electrical stimulation with an output lower than the motor nerve threshold, the electrical stimulation is sufficiently effectively transmitted, for example, exceeding one hour. Long time is required. Therefore, patients with dysphagia need to continue receiving treatment or the like with the electrical stimulator attached to the neck for a long time.

However, in the electrical stimulation devices described in Patent Documents 1 and 2, the electrode for transmitting electrical stimulation is directly and firmly fixed to the patient's neck using a large fixing tool that covers the entire patient's neck. Yes. For this reason, the electrical stimulation devices described in Patent Documents 1 and 2 are limited in movement near the patient's neck while being worn. There was a problem of being big.
For such a problem, for example, by fixing an electrode to the patient's neck using an adhesive gel pad that can be attached to the neck, electrical stimulation can be performed without fixing the entire patient's neck. There has also been proposed an electrical stimulation device that can transmit. However, during long-term treatment using an electrical stimulator, the patient's body movement during treatment and the contraction movement of the cervical muscles such as the laryngeal elevation muscles induced by the electrical stimulation emitted by the electrical stimulator For example, the patient's clothes and the gel pad of the electric stimulator may rub against each other. Therefore, an electrical stimulation device that fixes an electrode using only an adhesive gel pad can secure a degree of freedom of movement in the vicinity of the neck of the patient wearing the device, but it can be used for long-term treatment, etc. In the meantime, due to the above-described contraction of the muscle group and repeated movements of the patient, the electrodes of the electrostimulator are displaced, or the gel pad is peeled off from the neck, so that the electric There was a possibility that the stimulus could not be transmitted sufficiently. In addition, when the electrode is partially peeled, there is a problem that the skin density is caused by a relative increase in the current density of the remaining contact surface with the skin. Therefore, even when an electrical stimulation device using such a gel pad is used, the patient is required to rest for a long time in order to prevent the electrode from being displaced or dropped.

  Therefore, the present invention provides an electrical stimulation device that can reduce the burden on the user when the device is worn and can prevent the electrode from being displaced or dropped due to the user's body movement or the like. With the goal.

  A cervical electrical stimulation device according to the present invention is for applying electrical stimulation to a cervical part of a living body, and includes an oscillator that oscillates an electrical stimulation pulse, and the electrical stimulation pulse that is oscillated by the oscillator. An electrode that transmits to the neck, an adhesive member that is attached to the surface of the neck and attaches the electrode to the neck, and an adhesive member that is wound around the neck and attaches the adhesive member to the surface of the neck And the band is disposed so as to be relatively movable in both the width direction and the longitudinal direction of the band with respect to the adhesive member, and the band is relatively moved with respect to the adhesive member. A relative movement restricting mechanism for restricting a possible range is further provided.

Here, in the cervical electrical stimulation device of the present invention, the cervical electrical stimulation device is disposed on the non-adhesion surface side of the adhesive member opposite to the application surface side of the neck portion, and the band Preferably, the band holding member has an insertion part through which the band is inserted, and the relative movement restricting mechanism is preferably formed to include the insertion part.
In the above-described case, the relative movement restriction mechanism includes a movement restriction space formed in the insertion portion and a movement restriction member provided integrally with the band and accommodated in the movement restriction space. Is preferred.
Furthermore, in the above-described case, it is preferable that at least one of the movement restriction space and the movement restriction member is circular or elliptical in plan view.

  In the cervical electrical stimulation device according to the present invention, the cervical electrical stimulation device is disposed on the non-adhesion surface side of the adhesive member opposite to the adhesion surface side of the neck portion to cover the band. A band holding member that is disposed between the non-sticking surface of the adhesive member and the band holding member, and the relative movement restricting mechanism includes the band holding member and the adhesive member. The movement restricting space formed by the non-sticking surface and the movement restricting member provided integrally with the band and accommodated in the movement restricting space, and the adhesive member on the non-sticking surface A movement restricting member is formed to be slidable, and the height of the movement restricting space is lower than the center side on the peripheral side of the movement restricting space, and the height of the peripheral side of the movement restricting space is the movement restricting member Smaller than the outer peripheral thickness It is preferable.

  Furthermore, in the cervical electrical stimulation device of the present invention, the cervical electrical stimulation device is disposed on the non-adhesion surface side of the adhesive member opposite to the application surface side of the neck portion, and the band is A band holding member to be attached; and a movement restricting member provided integrally with the adhesive member on the non-sticking surface of the adhesive member, wherein the band holding member is engaged with the movement restricting member. Preferably, the relative movement restriction mechanism includes the engagement portion and the movement restriction member.

  By the way, in the neck electrical stimulation apparatus of this invention, it is preferable that the outer surface on the opposite side to the said adhesion member side of the said band holding member becomes a curved surface.

  Furthermore, in the cervical electrical stimulation device of the present invention, in the cross section along the longitudinal direction of the band, the length from the sticking surface to the surface of the band holding member opposite to the adhesive member side is the band holding It is preferable to gradually decrease from one side of the member toward the other side.

  According to the cervical electrical stimulation device of the present invention, since the cervical electrical stimulation device includes the adhesive member, the electrode can be attached to the cervical region without using a large fixture covering the entire cervical region. Therefore, it is possible to reduce the physical and mental burden of the user due to the movement of the vicinity of the neck being restricted during wearing. Furthermore, according to the cervical electrical stimulation device of the present invention, since the adhesive member is held using the band, it is possible to prevent the electrode from being detached from the neck or being displaced. The electrode can be used to apply electrical stimulation pulses to the neck. The band is disposed so as to be relatively movable in both the width direction and the longitudinal direction of the band with respect to the adhesive member, and a relative movement restricting mechanism for restricting a range in which the band can be relatively moved with respect to the adhesive member. Therefore, compared with the case where the adhesive member and the band are fixed so that the relative movement is not possible while preventing the band from moving excessively with respect to the adhesive member, the pulse for body movement or electrical stimulation of the user is provided. Even when the band is pulled due to the contraction movement of the muscular group of the neck induced by the above, it is possible to prevent the electrode from being pulled and moved together with the band. That is, it is possible to allow movement of the band while maintaining the position where the adhesive member is attached to the neck and preventing displacement of the electrode.

It is a general view which shows 3rd embodiment of the neck electrical stimulation apparatus of this invention.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
A cervical electrical stimulation device 1 shown in FIG. 1 is used for applying electrical stimulation to a cervical part of a living body. More specifically, the cervical electrical stimulation device 1 is used to treat dysphagia, which is a state in which any of a complex series of movements of the oral cavity, pharynx, and esophagus that swallow food occurs. It provides electrical stimulation to cervical muscles, nerves and other tissues. Examples of cervical muscles, nerves, and other tissues include the laryngeal elevation muscle group and the glossopharyngeal nerve, vagus nerve, and superior laryngeal nerve that exist in the cervical region. Is considered effective for treatment.

Here, as shown in FIGS. 1 and 2, the cervical electrical stimulation device 1 includes an oscillator (not shown) that oscillates an electrical stimulation pulse, an electrode (not shown) that transmits the electrical stimulation pulse oscillated by the oscillator to the cervix, An adhesive member 2 that is attached to the surface of the neck and attaches the electrode to the neck, and a band 3 that is wound around the neck and holds the adhesive member 2 attached to the surface of the neck. Yes. Moreover, in embodiment shown to FIG. 1 and 2, the neck electrical stimulation apparatus 1 is the band holding member 4 arrange | positioned at the non-sticking surface side on the opposite side to the sticking surface P side of the adhesion member 2 to the neck. Further, the oscillator is provided in the band holding member 4 in the drawing.
In the embodiment shown in FIG. 1, the cervical electrical stimulation device 1 includes one or more electrode units including the electrode and the adhesive member 2 in the state where the band holding member 4 is disposed on the electrode unit, and 2 in the drawing. Have one. Then, in the illustrated cervical electrical stimulation device 1, the user wears this device on the cervical region, whereby each electrode of the two electrode units is placed in front of the cervical region (for example, the laryngeal elevation muscle group is positioned). Location).

  The electrode unit having the band holding member 4 has a substantially circular shape in plan view as shown in FIG. 1 and has no corners. Therefore, when the user moves with the neck electrostimulator 1 attached to the neck, the electrode unit is not easily caught on the user's clothes. Here, the “substantially circular shape in plan view” includes, in addition to a circle and an ellipse, a shape obtained by deforming a part of the circumference within a range where an acute angle portion is not formed, as shown in FIG.

  As shown in FIG. 1 and FIGS. 2A and 2B, the adhesive member 2 has a substantially same outer peripheral contour as that of the band holding member 4 and has a flat plate shape. And the adhesion member 2 forms the surface of the one side (adhesion surface side with a neck part) of said electrode unit. The adhesive member 2 has an adhesive force that prevents the electrode unit from being peeled off by its own weight from the surface of the neck when the neck electrical stimulation device 1 is used, while the adhesive member 2 is removed from the neck. When peeling, the user has an adhesive force that does not cause pain. In general, since the surface of the neck is curved and is moved by the user's breathing and other body movements, the adhesive member 2 is preferably made of an elastically deformable material. Moreover, the electrode attached to the adhesive member 2 and an adhesive member can also be formed by apply | coating the material which has adhesiveness previously to a user's neck, and arrange | positioning an electrode on it.

The band holding member 4 is integrated with the adhesive member 2 in this embodiment on the opposite side of the adhesive member 2 from the side P of the neck surface attached to the neck surface (upward in FIGS. 2A and 2B). It is arranged adjacent to.
The adhesive member 2 and the band holding member 4 may be integrated using the adhesive force of the adhesive member 2, or an adhesive layer or a joint is provided between the adhesive member 2 and the band holding member 4. May be integrated. Further, the band 3 is attached to the band holding member 4 without being fixed to the band holding member 4. Furthermore, although the band holding member 4 is provided in the illustrated embodiment, the band holding member 4 is not an essential configuration in the cervical electrical stimulation device 1 of the present invention.

  The electrodes are not shown in the figure, but the electrical stimulation pulse oscillated by the oscillator contacts the surface of the neck and transmits it to the neck. It consists of a part. The electrode portion can be formed using any conductive member. The energization part is not particularly limited, and can be formed by, for example, a conductive lead cable. The electrode portion of the electrode may be configured using a conductive member that is separate from the adhesive member 2, or may be configured by an adhesive member formed using an adhesive and conductive member. Good (eg sticky gel). In addition, when an electrode part is comprised using the electroconductive member separate from the adhesive member 2, ie, an electrode is provided so that the adhesive member 2 may be penetrated, and an electrode part and neck part separate from the adhesive member 2 When the surface (ie, the user's skin) is in direct contact, a pulse for electrical stimulation can be applied at a desired position in a pinpoint manner. On the other hand, when the electrode portion is formed of the adhesive member itself, the number of parts of the cervical electrical stimulation device 1 can be reduced, and the electrical stimulation pulse can be applied over a wide range. Incidentally, when the electrode portion is configured using a conductive member separate from the adhesive member 2, there are a plurality of electrode portions depending on the position and range where the electrical stimulation pulse is to be applied and the type of electrical stimulation pulse. It may be provided. In addition, when the electrode part is constituted by the adhesive member itself, one adhesive member 2 insulates a plurality of electrode parts that transmit different types of electrical stimulation pulses to the neck, for example, between the plurality of electrode parts. You may have by providing a sex member. By providing a plurality of electrode portions, for example, interference medium frequency electrical stimulation can be performed.

The oscillator oscillates an electrical stimulation pulse (electric current for electrical stimulation) that serves as electrical stimulation for the neck. The oscillator is provided in the band holding member 4 as in the embodiment shown in FIGS. 1 and 2, or the band holding member 4, the adhesive member 2, the electrode, etc. as in the embodiment shown in FIG. And can be provided outside. When the oscillator 5 is separated and provided outside, as shown in FIG. 3A, the band holding member 4, the adhesive member 2, and the electrode energizing portion 6 that extends to the outside, such as an electrode, The electrode portion can be connected via the band holding member 4 and / or the adhesive member 2. And when providing an oscillator in the band holding member 4, the restriction | limiting of a user's movement at the time of mounting | wearing with the neck electrical stimulation apparatus 1 can be reduced, and a freedom degree can further be raised, On the other hand, the oscillator 5 is used. When provided externally, it is possible to make the electrode unit relatively small in burden on the patient, and to make the oscillator 5 provided externally relatively large. That is, by making the oscillator 5 relatively large, for example, a large-scale power source capable of applying electrical stimulation with a larger current or for a longer time, or an electrical stimulation parameter that matches individual patient symptoms is set. For example, a stimulation condition setting circuit can be used.
The oscillator 5 can be provided with a generating element that generates electrical stimulation pulses, a power source, and the like at an arbitrary position inside the oscillator, or a power source can be provided outside the oscillator separately from the oscillator. .

Further, as shown in FIG. 1, the band 3 is a band-shaped member, and at both ends, the neck 3 is easily attached to and detached from the neck. A connection portion 31 that can be connected to an end, for example, a hook-and-loop fastener, a line fastener, a point fastener (snap button), or the like is provided. In this embodiment, the band 3 is narrower than the band holding member 4 and is attached without covering the entire neck, unlike the large fixture of the neck electrical stimulation device 1 according to the prior art. (In other words, it is attached so as to cover a part of the neck in the length direction). The band 3 can be formed using any member that can be attached to the neck, for example, a belt-like member having stretchability, or a band-like elastic member (for example, plastic) that is garnished.
Here, the cervical electrical stimulation apparatus 1 shown in FIG. 1 connects two electrode units to the cervical portion by connecting one end and the other end of the band 3 with the connecting portion 31 positioned in front of the cervical portion, for example. However, in the cervical electrical stimulation device 1 of the present invention, the connection portion 31 and the electrode unit can be arbitrarily positioned. The band 3 can also be formed as an endless annular band.

And in the neck electrical stimulation apparatus 1 of this invention, as shown in FIG.2 (c), the band 3 is the longitudinal direction and longitudinal direction of the band 3 with respect to the adhesion member 2 (FIG.2 (c)). The cervical electrical stimulation device 1 is disposed so as to be relatively movable in both directions (left and right directions in FIG. 2C), and the neck electrostimulation device 1 regulates a range in which the band 3 can relatively move with respect to the adhesive member 2. A movement restricting mechanism 7 is further provided.
Therefore, according to the cervical electrical stimulation device 1, the electrode can be attached to the surface of the cervix by the adhesive member 2 provided in the cervical electrical stimulation device 1, and therefore it is necessary to use a large fixing tool that covers the entire cervical region. Absent. Therefore, it is possible to reduce the physical and mental burden of the user due to the movement of the vicinity of the neck being restricted during the wearing of the neck electrical stimulation device 1. Further, since the band 3 holds the electrode attached to the neck surface by the adhesive member 2 on the neck surface, the electrode can be removed while preventing the electrode from being detached from the neck or being displaced. It can be used to apply electrical stimulation pulses to the neck. In addition, the band 3 is disposed so as to be relatively movable with respect to the adhesive member 2 in both the width direction and the longitudinal direction of the band 3, and the relative movement restriction mechanism 7 is provided. Even if the band 3 is pulled due to the contraction movement of the muscular group of the neck induced by the body movement or electrical stimulation pulse, the movement range of the band 3 relative to the adhesive member 2 is excessive by the relative movement restriction mechanism 7. The adhesive member 2 can be prevented from being pulled and moved together with the band 3 while being prevented. That is, while the adhesive member 2 is attached to the surface of the neck, only the band 3 is moved relative to the adhesive member 2 within an appropriate range, thereby maintaining the position where the adhesive member 2 is attached to the neck. The movement of the band 3 by pulling or the like can be allowed. Therefore, it is possible to prevent the displacement of the electrode due to the body movement of the user who attached the electrode for oscillating the electrical stimulation pulse to the neck. As a result, a user wearing the neck electrical stimulation device 1 on the neck can receive treatment using electrical stimulation for a long time without being greatly restricted in body movement.

  Here, in the cervical electrical stimulation device 1, as shown in FIG. 2, when the band holding member 4 has an insertion part 71 through which the band 3 is inserted, the relative movement restriction mechanism 7 has the insertion part 71. It is preferable to be formed. According to this, it becomes possible to easily change the relative position of the electrode in the longitudinal direction with respect to the band. Since the user of the apparatus can easily change the distance between the electrodes, the electrodes can be installed without trouble at the distance between the electrodes in accordance with the patient's neck.

As shown in FIG. 2, the insertion portion 71 is located substantially at the center of the oscillator in this embodiment. As shown in FIG. 2, the insertion portion 71 forms a rectangular parallelepiped space having a width and height larger than the width and thickness of the band 3 inside the band holding member 4.
The insertion portion 71 can be disposed at any position such as near the outer surface of the band holding member 4 as long as the band 3 can be inserted into the band holding member 4. Moreover, the shape of the insertion part 71 is not limited to the shape to show in figure.

  By the way, from the viewpoint of preventing the clothes from being caught on the band holding member 4 due to, for example, the user's body movement during use of the cervical electrical stimulation device 1 and unintentional displacement of the electrodes from occurring, as shown in FIG. Thus, it is preferable that the outer surface of the outer surface of the band holding member 4 opposite to the adhesive member 2 side is a curved surface. Specifically, for example, in a cross-sectional view along the arbitrary direction of the band holding member 4, it is preferable that portions other than the surface on the adhesive member 2 side of the band holding member 4 draw a curve having no unevenness. When the band holding member 4 is not provided, the adhesive member 2, the electrode and the relative movement restricting mechanism 7, and the adhesive that sticks to the surface of the neck including the oscillator when the oscillator is formed integrally with these members. It is preferable that the outer surface other than the surface is a curved surface having no unevenness.

Then, as shown in FIGS. 1 and 2 (a), in the longitudinal direction of the band 3, specifically, in a cross section along the circumferential direction of the neck when the neck electrostimulator 1 is attached to the neck, The length from the surface P to the surface of the band holding member 4 opposite to the adhesive member 2 side is one side of the band holding member 4 (in the illustrated example, the front side of the neck when the neck electrostimulator 1 is mounted). It is preferable to reduce gradually from the connection part 31 side located in the center) toward the other side.
The side part of the neck is easily touched by the collar of the clothes, but if the length is gradually reduced in this way, for example, the electrode is placed on the front surface of the neck and the other side of the electrode is the side of the neck. This is because it is possible to suppress the occurrence of positional displacement of the electrode by suppressing the clothes collar and the like from coming into contact with the electrode and the band holding member 4 and the like when being attached in a form facing the surface.
In addition, as in this embodiment shown in FIG. 1, when the cervical electrical stimulation device 1 is normally provided with two electrode units, one side of the electrode unit (the side with the longer cross-sectional length) is the front of the cervical part. Attach so that they face each other across the center.

  Here, in the case where the place where electrical stimulation is performed is from under the cervical submandibular region, a band 3 branched in the middle is used as shown in FIG. You can also.

Then, the modification of the relative movement control mechanism of the neck electrical stimulation apparatus of this invention is demonstrated using FIG. Below, detailed description is abbreviate | omitted about the member which has the structure similar to the previous neck electrical stimulation apparatus 1. FIG.
A cervical electrical stimulation device 101 according to a modification of the present invention includes an oscillator, an electrode, an adhesive member 102, a band 103, a relative movement restricting mechanism 107, and a band holding member 104, similarly to the cervical electrical stimulation device 1 described above. Yes. In the neck electrical stimulation device 101, the relative movement restriction mechanism 107 further includes a movement restriction space 172 and a movement restriction member 173. Specifically, as shown in FIG. 4C, the relative movement restricting mechanism 107 moves integrally with the movement restricting space 172 formed in the insertion portion 171 of the band holding member 104 and the band 103. The movement restriction member 173 is accommodated in the restriction space 172.
According to this embodiment of the cervical electrical stimulation apparatus 101 of the present invention, in addition to the same effects as those of the previous cervical electrical stimulation apparatus 101, the following effects are further obtained. In other words, the insertion portion 171 allows the band 103 to move relative to the adhesive member 102, while the movement restricting member 173 restricts the movable range of the band 103 within the movement restricting space 172. Accordingly, the band 103 can be prevented from moving greatly, and the movable range of the band 103 can be appropriately limited to apply electrical stimulation to the neck of the user. Further, by using the band 103 and the movement restricting member 173 formed integrally with the band 103, a force in a direction of pressing the adhesive member 102 against the neck can be applied in a wide area. Therefore, compared with the case where the movement restricting member 173 is not provided, the adhesive member 102 can be more firmly attached to the surface of the neck portion, and displacement of the electrode can be prevented. Furthermore, the movement restricting member 173 is in contact with the inner wall in the movement restricting space 172, so that the movement range is restricted, and the band 103 does not directly contact the wall surface in the insertion portion 171. The occurrence of twisting of the band 103 can be suppressed.

  Here, the insertion portion 171 of this embodiment has a pair of cross-sectional shapes parallel to the band 103 attached to the band holding member 104 and having a width larger than the width of the band 103 as shown in FIG. And an approximately circular main body portion that is once widened from the opening portion on one side toward the opening portion on the other side and then reduced in width. A movement restriction space 172 is formed inside the main body of the insertion portion 171. Note that the movement restriction space 172 can have a shape that matches the shape of the movement restriction member 173 and the range in which the movement of the band 103 is desired to be restricted. In addition to the circular space as shown in the figure, an elliptical shape, a curved shape, Alternatively, it can be a square space. More preferably, at least one of the movement restricting space 172 and the movement restricting member 173 is circular or elliptical in plan view. The movement restricting member 173 can move smoothly in all directions within the movement restricting space 172, and can return to the original position without being caught after the movement restricting member 173 has moved.

  4A and 4B, the height of the movement restriction space 172 is equal to the height of the space formed by the opening of the insertion portion 171. Note that the height of the movement restricting space 172 can be increased by making the height of the opening portion of the insertion portion 171 different from that of the main body portion.

As shown in FIG. 4C, the movement restricting member 173 has a maximum width in a direction parallel to the width direction of the band 103 larger than the width of the opening of the insertion portion 171, and the movement restricting member 173 as a whole from the opening. Is configured not to jump out of the movement restriction space 172. The movement restricting member 173 has a size that can be accommodated in a movement restricting space 172 formed on the inner peripheral side of the main body. The movement restriction member 173 can be accommodated in the movement restriction space 172 by, for example, forming the band holding member 104 so as to be split at the position of the insertion portion 171.
Further, as shown in FIGS. 4A and 4B, the thickness of the movement restricting member 173 is larger than the thickness of the band 103 and can slide smoothly in the movement restricting space 172. It is formed to be smaller than the height of the movement restriction space 172.
The movement restricting member 173 may be, for example, a disk shape, an elliptical shape, another curved surface shape, or a rectangular shape as shown in FIG. From the viewpoint of smoothly moving the movement restricting member 173, the movement restricting member 173 preferably has a disk shape.
Furthermore, the movement restricting member 173 can have an arbitrary shape. Incidentally, when the shape of the movement restricting member 173 is an arbitrary shape (for example, a rhombus), a part of the movement restricting member 173 may extend out of the movement restricting space 172. If at least a part of the restriction member 173 is accommodated in the movement restriction space 172, the movement restriction member 173 is considered to be in a state of being accommodated in the movement restriction space 172.

  The dimension of the movement restricting member 173 is a dimension in which the movement restricting member 173 abuts against the inner wall surface of the movement restricting space 172 before the band 103 abuts against the opening when the band 103 relatively moves. It can be of any size.

  Here, in the cervical electrical stimulation device 101, the height of the movement restriction space 172 can be made substantially the same as described above, while the height of the movement restriction space 172 is moved. The movement restriction space 172 can be formed into a mortar shape by lowering the height of the restriction space 172 on the peripheral side from the center side, for example, gradually decreasing the height from the center side toward the peripheral side. According to this, when the user wears the cervical electrical stimulation device 101, the movement restricting member 173 that moves together with the band 103 is higher than the center side where the height of the movement restricting space 172 is relatively high. It becomes difficult to slide on the relatively low peripheral side. Therefore, the significant movement of the band 103 can be more appropriately restricted.

Next, another modified example of the relative movement restriction mechanism of the cervical electrical stimulation device of the present invention will be described with reference to FIG. In the following, detailed description of members having the same configuration as that of the neck electrical stimulation devices 1 and 101 is omitted.
A cervical electrical stimulation device 201 according to another modification of the present invention includes an oscillator, an electrode, an adhesive member 202, a band 203, a relative movement restricting mechanism 207, and a band holding member 204, similar to the cervical electrical stimulation devices 1 and 101 described above. Have Note that the band holding member 204 covers the band 203 from above, unlike the above-described neck electrical stimulation devices 1 and 101 which are attached by inserting the bands 3 and 103 into the band holding members 4 and 104. Yes.
In this embodiment, as shown in FIG. 5, the non-sticking surface N in a state where the side opposite to the sticking surface P side of the adhesive member 202 to the neck is not directly coupled to the band holding member 204. It is formed as. In addition, the band 203 is disposed between the separated band holding member 204 and the adhesive member 202, and a connecting member 208 having a certain length for connecting the band holding member 204 and the adhesive member 202 is illustrated in the drawing. The band holding member 204 and the adhesive member 202 are provided at the central part. The connecting member 208 can be provided at any position other than the central portion.

That is, in this embodiment, the adhesive member 202 has a non-stick surface N, and the non-stick surface N is slid by the band 203 and the movement restricting member 273 formed integrally with the band 203 thereon. The band holding member 204 is disposed thereon. The adhesive member 202 having the non-sticking surface N can be formed by laminating a resin film on a member having adhesiveness, for example.
Further, the band holding member 204 has a recess 274 formed on the bottom surface side (adhesive member 202 side), and the recess 274 and the adhesive member 202 are connected by a connecting member 208. The recess 274 has a mortar shape in the illustrated example. That is, the depth of the recess 274 increases toward the center.
The connecting member 208 connects the adhesive member 202 and the band holding member 204, and is not particularly limited, and can be formed of an elastic member such as a spring or rubber. In this embodiment, a part of the electrode may be configured by forming the connecting member 208 with a conductive member.
A space between the concave portion 274 formed in the band holding member 204 and the adhesive member 202 facing the concave portion 274 becomes a movement restriction space 272. That is, the movement restriction space 272 is formed on the non-sticking surface N of the adhesive member 202. Since the concave portion 274 is deeper toward the center side, the movement restricting space 272 is higher toward the center side.
Further, the movement restricting member 273 formed integrally with the band 203 is accommodated in the movement restricting space 272. In this example, the movement restricting member 273 has a shape corresponding to the shape of the movement restricting space 272, that is, a mountain shape in which the center side is higher than the peripheral side. Further, the movement restricting member 273 has a cylindrical hollow portion 273a through which the connecting member 208 penetrates at the center. The adhesive member 202 and the band holding member 204 using the connecting member 208 can be connected by a screw, a fitting button, a magnet, or the like.

  Here, in this embodiment, in a state where the movement restriction member 273 is accommodated in the movement restriction space 272 and is positioned at the center of the space, the height H on the peripheral side of the movement restriction space 272 is equal to the height of the movement restriction member 273. The height of the central portion of the movement restricting space 272 is smaller than the thickness T on the outer peripheral side, and is greater than the thickness of the central portion of the movement restricting member 273. Therefore, if the movement restricting member 273 moves from the central portion to the peripheral side in the movement restricting space 272, the movement restricting member 273 and the inner surface of the concave portion 274 of the band holding member 204 forming the movement restricting space 272 come into strong contact. It will be. Since the band holding member 204 and the adhesive member 202 are connected by the connecting member 208, when the movement restricting member 273 further moves to the peripheral side, the movement restricting member 273 attaches the adhesive member 202 to the sticking surface P side. It will slide while being pressed.

Therefore, in the cervical electrical stimulation apparatus 201 of the present invention, the following effects can be obtained in addition to the same effects as the previous cervical electrical stimulation apparatuses 1 and 101.
That is, when the movement restriction member 273 slides in the movement restriction space 272 toward the peripheral side of the movement restriction space 272, the movement restriction member 273 further moves the non-sticking surface N of the adhesive member 202 to the sticking surface P side. It moves with strong pressure. Therefore, the adhesive member 202 is more firmly attached to the surface of the neck by sliding the band 203, and the positional displacement of the electrode can be more effectively prevented.

  Here, although illustration is omitted, when the adhesive member 202 has a non-attachment surface N opposite to the attachment surface P side to the neck, the thickness of the adhesive member 202 is the peripheral side of the adhesive member 202. It is preferably larger than the center side and gradually increased from the center side toward the peripheral side. According to this, when the movement restricting member 273 slides in the movement restricting space 272 toward the peripheral edge of the movement restricting space 272, the movement restricting member 273 more effectively presses the adhesive member 202 against the neck surface. be able to.

Next, a second embodiment of the cervical electrical stimulation device of the present invention will be described with reference to FIG. In the following, detailed description of members having the same configuration as that of the previous cervical electrical stimulation apparatus 1, 101, 201 will be omitted.

Have
In this embodiment, as shown in FIG. 6, the non-sticking surface N in a state in which the side opposite to the sticking surface P side of the adhesive member 302 to the neck is not directly coupled to the band holding member 304 and separated. It is formed as.
In the cervical electrical stimulation device 301, a band 303 is attached to a band holding member 304. In this embodiment, the band 303 is attached to the band holding member 304 by fixing the band 303 integrally to the outer surface other than the non-sticking surface N of the band holding member 304, or as described above. It is realizable by providing and inserting.

In this embodiment, a movement restricting member 373 provided integrally with the adhesive member 302 is provided on the non-sticking surface N of the adhesive member 302 in the center of the adhesive member 302 in the drawing. Further, the band holding member 304 has an engaging portion 375 that engages with the movement restricting member 373. In this embodiment, the relative movement restriction mechanism 307 includes the engagement portion 375 and a movement restriction member 373.
Specifically, as shown in FIGS. 6A to 6C, the relative movement restriction mechanism 307 includes a disk-shaped member as the movement restriction member 373 and a bottom surface of the band holding member 304 as the engagement portion 375. It can be comprised with the hollow part 375a formed in the side (adhesive member 302 side).
Therefore, when the band 303 moves when the user wears the neck electrostimulator 301 on the neck, the relative movement restriction mechanism 307 moves the disc-shaped member inside the recess 375a, so that the adhesive member The band 303 can be relatively moved with respect to 302, and the disk-like member functions to regulate the relative movement by contacting the peripheral edge of the recess 375a. When the thickness of the disk-shaped member is larger than the depth of the recessed portion 375a, the engaging portion 375 of the band holding member 304 slides on the surface of the movement restricting member 373, while the thickness of the disk-shaped member. Is smaller than the depth of the recessed portion 375a, the band holding member 304 is formed to be slidable on the non-sticking surface N so that the movement of the band holding member 304 is restricted by the relative movement restriction mechanism 307. Slide on the pasting surface N.

Therefore, the cervical electrical stimulation apparatus 301 according to the second embodiment of the present invention can obtain the following effects in addition to the same effects as those of the previous cervical electrical stimulation apparatuses 1, 101, and 201.
That is, when the band 303 and the band holding member 304 move relative to the adhesive member 302 while being pulled toward the sticking surface P side of the adhesive member 302, the movement is restricted by the relative movement restriction mechanism 307. However, since the movement restricting member 373 and the engaging portion 375, or the band holding member 304 and the non-sticking surface N slide, the adhesive member 302 is further strongly pressed and moved to the sticking surface P side by the sliding. It becomes. Therefore, the adhesive member 302 is more firmly attached to the surface of the neck by sliding the band 303, and the positional deviation of the electrodes can be prevented more effectively.

  Here, in this embodiment, when the neck electrical stimulation device 301 is attached to the neck, the movement restricting member 373 and the engaging portion 375 shown in FIGS. By holding the adhesive member 302 via the band holding member 304, the band holding member 304 is prevented from being separated from the adhesive member 302. However, in order to more reliably connect the band holding member 304 and the adhesive member 302, it is preferable to provide the above-described connecting member (not shown) for connecting the band holding member 304 and the adhesive member 302. Moreover, a part of electrode can also be comprised by forming a connection member with an electroconductive member.

  Further, as shown in FIG. 6D, the movement restricting member 373 has a diameter-enlarged portion 373b obtained by enlarging the distal end portion of the disc-shaped member on the band holding member 304 side. When the reduced diameter portion 375b having a diameter smaller than the enlarged diameter portion 373b is provided on the non-sticking surface N side of the recess portion 375a, and the adhesive member 302 and the band holding member 304 are moved in the direction of separation, The respective portions 373b and 375b may be formed so as to contact each other. The connection between the band holding member 304 and the adhesive member 302 can be further ensured.

  In this embodiment, the width of the band 303 can be the same as or wider than the band holding member 304. Thereby, even if the band 303 moves, the band 303 can press the whole adhesive member 302 to the neck part via the band holding member 304, and can adhere the adhesive member 302 more strongly.

  For any of the neck electrostimulation devices described above, the electrode unit, particularly the adhesive member, is made to have a curved shape so as to correspond to the shape of the neck surface to which the electrode and / or band holding member is attached. However, it is preferable from the viewpoint of preventing the displacement of the electrode.

  In addition, as shown in FIG. 7, the cervical electrical stimulation device 401 includes an additional energization unit 461 of a conductive cable that extends from the oscillator or branches from the electrode separately from the electrode held by the band 403. , An additional electrode composed of an additional electrode portion for transmitting the electrical stimulation pulse oscillated by the oscillator to the neck portion via the additional energization portion 461, and an additional adhesive member 421 for attaching the additional electrode portion to the surface of the neck portion, At least one electrode unit can be provided. According to this, when the user attaches the cervical electrical stimulation device 401 to the cervix, the electrode and the additional electrode are placed on the surface of the cervix, for example, the electrode is placed on one side of the pair of muscles of the cervix. By applying the additional electrode to the other side of the pair of muscles (in FIG. 7, the additional electrodes provided in the two electrode units cross each other), the neck can be more efficiently subjected to electrical stimulation. it can.

  When the cervical electrical stimulation device 401 has an additional electrode, the cervical electrical stimulation device 401 holds and accommodates the additional electrode on the electrode unit, for example, on the outer surface of the band holding member 404 as shown in FIG. A possible mounting portion 401a made of a curved surface, which is recessed in the drawing, can be provided.
