Abstract
The present utility model relates to an adjustable low frequency device for alleviating muscular and joint pain, which can be easily attached to a human body part such as a joint by changing the posture with respect to a low frequency generator by rotating each contact plate, and in particular, since a plurality of contact plates formed in pairs are connected to each other by a sheet member for connection, a problem that the contact plates are easily separated from the low frequency generator during the posture change by rotating the contact plates or the use of attaching the contact plates to the human body does not occur.
Description
Technical Field
The present utility model relates to an adjustable low frequency device for relieving muscle and joint pain, and more particularly, to an adjustable low frequency device which can relieve muscle or joint pain by contacting a conductive contact plate to the skin and applying a minute low frequency current to the human body.
Background
In recent years, the general public has become more and more concerned about health, and various devices that are beneficial to health have been developed and widely popularized in the life of the general public.
The low frequency device is a medical device that stimulates muscles, tendons, ligaments, etc. by loading a low frequency current generated from a low frequency generator to a conductive contact plate that is in contact with the skin, and thereby achieves a therapeutic effect.
Recently, considering that the same effect as weight training can be achieved by muscle stimulation using a low frequency device, the low frequency device is also used as an exercise device for directly stimulating muscles.
As the related art related to the low frequency device as described above, there are included "low frequency therapeutic apparatus" of korean registered utility model No. 20-0392565 (2005.8.3. Registered), "electrotherapy stimulator for deep muscle stimulation" of korean published patent No. 10-2014-014190 (2014.9.24. Published), and "weight loss and therapy belt using a low frequency plate" of korean published patent No. 10-2015-0105062 (2015.9.16. Published), and the like.
The low frequency device comprises a plurality of conductive contact plates formed in pairs and in contact with the skin, and a low frequency generator for loading a minute low frequency current limit through the conductive contact plates.
Fig. 1 is a conceptual diagram of a low frequency device based on the prior art.
The low frequency device in fig. 1 is widely used for medical use, and is configured such that the conductive contact plates 3 are respectively coupled to two wires 2 extending from the low frequency generator 1 so that the conductive contact plates 3 formed in pairs can be freely adhered to a body part.
The low frequency apparatus of the above-described form is widely applicable to hospitals or households because the conductive contact plate 3 is freely connected to the two electric wires 2, and thus the user needs to sit still on a bed or sit still on a chair in use.
In order to perform physical activities in a state where the low frequency device is worn, it is necessary to fix the conductive contact plate 3 to the body by a belt and hold the low frequency generator 1 connected by the electric wire 2 on the hand or to be housed in a pocket or the like.
Fig. 2 is a conceptual diagram of another low frequency device based on the related art, and fig. 3 is a conceptual sectional view of the low frequency device in fig. 2.
The low frequency device in fig. 2 is a form of a low frequency exercise device that obtains exercise effects by stimulating muscles, and the low frequency generator 4 for generating a low frequency current is small in size and integrated with the conductive contact plate 5, so that physical activity can be performed in a worn state.
The compact low frequency device as described above is manufactured in a fixed muscle form and is usually specially adapted to a specific site such as the abdominal muscle or thigh muscle. Moreover, it is mainly used for obtaining exercise effects by stimulating muscles, not for pain relief or treatment.
That is, it is difficult to realize multi-site versatility, and there is a problem that it cannot be applied to sites where the body is folded or protruded, such as joints.
Further, since the conductive contact plate 5 of the compact low frequency device as described above is integrated into the low frequency generator 4, it is difficult to partially replace or repair when damage occurs to the conductive contact plate 5.

Effects of the utility model
The adjustable low frequency device to which the present utility model is applied as described above can be used by changing the posture of the low frequency generator by rotating the respective contact plates, and can be easily attached to a human body part such as a joint or the like.

An adjustable low frequency device to which one embodiment of the present utility model is applied includes: a low frequency generator 100 for generating a low frequency current; and a conductive plate part 200 that transmits a low frequency current to a human body by being stuck to the skin in a state of being coupled into the low frequency generator 100.
The low frequency generator 100 is a device for generating a low frequency current, and is provided with an operation button (not shown in the drawing) for performing an on/off operation and adjusting the intensity of the low frequency current and an indicator (not shown in the drawing) for displaying the intensity of the low frequency current on the upper side.
The battery is integrally provided inside the low frequency generator 100 of the present embodiment, so that the charging operation can be simply performed using the charger.
A 1 st coupling terminal portion 110 for outputting the low-frequency current generated from the low-frequency generator 100 is provided on the lower side surface of the low-frequency generator 100. The 1 st bonding terminal parts 110 are formed in pairs and arranged at a certain interval. In the present embodiment, 21 st bonding terminal parts 110 formed in pairs are provided. In different embodiments, 4 or 6 1 st bonding terminal parts 110 may be provided.
The 1 st bonding terminal part 110 is detachably bonded to the 2 nd bonding terminal part 220 of the conductive plate part 200, and the structure of the detachable bonding may be selected according to various embodiments. As an example, the 1 st coupling terminal part 110 and the 2 nd coupling terminal part 220 may adopt a structure composed of male/female snap fasteners.
The 1 st and 2 nd coupling terminal portions 110 and 220 of the present embodiment realize a detachable coupling structure by means of magnetism. By using the magnetic bonding method, the low frequency generator 100 and the conductive plate portion 200 can be easily bonded even without directly confirming the positions of the 1 st bonding terminal portion 110 and the 2 nd bonding terminal portion 220 with the naked eye.
As can be seen from fig. 6, the 1 st coupling terminal portion 110 includes a 1 st magnetic coupling plane 110a in an annular shape for magnetically coupling with the 2 nd coupling terminal portion 220, and a circular insertion groove 110b recessed from the center thereof to the upper portion.
The specific structure of the 1 st bonding terminal part 110 is shown in fig. 7. As can be confirmed from the drawings, the 1 st coupling terminal portion 110 of the present embodiment includes a terminal housing 111 and a magnet 112, and a housing cover 113.
The terminal housing 111 has a cylindrical shape with an open upper portion, and an insertion groove through hole 111a for forming the insertion groove 110b is formed in the center of the terminal housing 111.
The 1 st magnetic coupling plane 110a is formed at the lower side of the terminal housing 111.
A magnet housing portion 111b for housing the magnet 112 is formed inside the terminal housing 111.
Further, a plurality of clips 111c for fixing the housing cover 113 are formed at the upper edge of the terminal housing 111.
The magnet 112 is inserted into the magnet receiving portion 111b of the terminal housing 111 so that the 2 nd coupling terminal portion 220 is magnetically coupled with the 1 st coupling terminal portion 110.
The magnet 112 is formed in a doughnut shape so that the insertion groove 110b can be formed together with the insertion groove through hole 111a in a state of being inserted into the magnet housing portion 111b of the terminal housing 111. The insertion groove 110b of the 1 st coupling terminal portion 110 formed by the insertion groove through hole 111a and the magnet 112 can be confirmed specifically by fig. 9.
The case cover 113 is coupled to the terminal case 111, and is inserted into the magnet housing portion 111b together with the magnet 112 so as to cover the magnet inserted into the magnet housing portion 111b, so that the magnet 112 inserted into the terminal case 111 is prevented from being separated from the terminal case 111, and the case cover 113 can be fixed by folding the clip piece 111c of the terminal case 111 inward.
Further, the terminal housing 111 is made of a metal through which current can flow.
Next, the conductive plate portion 200 magnetically incorporated into the low frequency generator 100 will be described.
The conductive plate portion 200 includes a connection sheet member 210 equipped with a plurality of 2 nd coupling terminal portions 220, and a plurality of contact plates 230 for transmitting a low-frequency current to a human body by being rotatably coupled to the connection sheet member 210.
The connection sheet member 210 of the present embodiment is a heart-shaped sheet-like shape covering all of the 1 st coupling terminal portions 110 provided in the low frequency generator 100.
The connection sheet member 210 is provided with a plurality of 2 nd coupling terminal portions 220 electrically connected to the 1 st coupling terminal portion 110 by being detachably coupled to the 1 st coupling terminal portion 110.
By incorporating the 2 nd coupling terminal portions 220 into the 1 st coupling terminal portion 110 as described above, the connection sheet member 210 will be removably coupled to the lower side surface of the low frequency generator 100.
A pair of 1 st through holes 211 for rotatably coupling the 2 nd coupling terminal portion 220 are formed in the connection sheet member 210 at positions corresponding to the 1 st coupling terminal portion 110. The 1 st through hole 211 is penetrated by a shaft boss 221d of the detachable terminal block 211 to be described later.
A pair of 2 nd coupling terminal portions 220 are rotatably coupled to the connection sheet member 210. Since the 2 nd coupling terminal portion 220 is coupled to the 1 st through hole 211 formed at a position corresponding to the 1 st coupling terminal portion 110, the posture of the connection sheet member 210 coupled to the low frequency generator 100 through the 2 nd coupling terminal portion 220 will be in a fixed state with respect to the low frequency generator 100.
At the lower end portions of the 2 nd coupling terminal portions 220, contact plates 230 for transmitting the low-frequency current generated in the low-frequency generator 100 to the human body are coupled, respectively. The plurality of contact plates 230, one side of which is coupled to the 2 nd coupling terminal portion 220, are rotatable together with the 2 nd coupling terminal portion 220 with respect to the sheet member for connection 210. This makes it possible to change the posture of the plurality of contact plates 230 with respect to the connection sheet member 210 and the low frequency generator 100.
The contact plate 230 receives the low frequency current generated from the low frequency generator 100 through the 1 st and 2 nd coupling terminal portions 110 and 220 and transmits the current to the human body.
As can be seen from fig. 7, the 2 nd coupling terminal portion 220 of the present embodiment includes a terminal block 221 for attachment and detachment, a contact plate coupling piece 222, and 1 st and 2 nd washers 223, 224.
The detachable terminal block 221 is composed of a terminal body 221c and a shaft boss 221d, and is made of a magnetizable and electrically conductive metal.
On the upper side of the terminal body 221c, there are formed a 2 nd magnetic coupling plane 221a which is in surface contact with the 1 st magnetic coupling plane 110a by being magnetically coupled to the 1 st magnetic coupling plane 110a of the 1 st coupling terminal portion 110, and an insertion protrusion 221b in the form of a cylinder which is inserted into the insertion groove 110b of the 1 st coupling terminal portion 110 by protruding upward from the 2 nd magnetic coupling plane 221 a.
The shaft protrusion 221d is formed to protrude from a lower side of the terminal body 221c toward a lower portion, and a blocking head 221e (not shown in fig. 7) is formed at an end of the shaft protrusion 221 d. The stopper 221e may be formed by welding or soldering a metal sheet, and in this embodiment, the stopper 221e is formed by pressing an end portion of the shaft boss 221d and forming a rivet head.
The stopper 221e functions to integrally join the connection sheet member 210 and the 1 st washer 223 and the contact plate joining piece 222 to the shaft boss 221 d. The blocking head 221e cannot be checked in fig. 7 illustrating a state in which the 2 nd coupling terminal portion 220 is separated, whereas the blocking head 221e can be checked in fig. 8 illustrating a state in which the 2 nd coupling terminal portion 220 is coupled.
That is, the attachment/detachment terminal block 221 is manufactured in the form shown in fig. 7, and the lower end portion of the shaft boss 221d is pressed with the connection sheet member 210, the 1 st washer 223, and the contact plate coupling piece 222 being fitted into the shaft boss 221d in this order to form the stopper 221e, thereby realizing the rivet coupling shown in fig. 8.
In addition to the above-described bonding method, bonding may be achieved by directly welding the contact plate bonding piece 222 to the shaft boss 221d in a state in which the connection sheet member 210 and the 1 st washer 223 are sequentially inserted into the shaft boss 221 d. That is, as a method of bonding the contact plate bonding sheet 222 to the shaft boss 221d, a variety of different schemes may be adopted.
The contact plate bonding sheet 222 of the present embodiment, which is bonded by rivet connection, includes a central body 222a for bonding, which is formed with a 3 rd through hole 222b and extends in the horizontal direction, and a pair of bonding wings 222c bent from the edge of the central boss 222a for bonding and extending downward.
The 3 rd through hole 222b is penetrated by the shaft protrusion 221d of the contact plate coupling piece 222, and a pair of coupling wings 222c are used to couple the contact plate 230 to the contact plate coupling piece 222.
In fig. 7, a pair of coupling wings 222c are shown in a "n" shape contact plate coupling piece 222 bent downward, and in fig. 8, a state is shown in which the end portions of the coupling wings 222c are bent in the horizontal direction in order to couple the contact plate 230 and the 2 nd gasket 224 to the contact plate coupling piece 222. The specific combination and method will be described later.
The 1 st washer 223 is in the form of a disk, and a 2 nd through hole 223a through which the shaft boss 221d passes is formed in the center. The 1 st washer 223 is interposed between the connection sheet member 210 and the contact plate coupling piece 222, and the shaft boss 221d is allowed to pass through the 2 nd through hole 223a.
The 2 nd gasket 224 is manufactured in the same disk shape as the 1 st gasket 223 by being coupled together with the contact plate 230 when it is coupled to the contact plate coupling piece 222. A pair of 2 nd slits 224a through which the pair of engaging wings 222c of the contact plate engaging piece 222 pass are formed in the 2 nd gasket 224.
The 1 st slit 234, which is not described in the above description, is formed in the contact plate 230, and a specific configuration of the contact plate 230 will be described next together.
The contact plates 230 of the present embodiment are formed in pairs with a narrow width on one side and a wide width on the other side. Each contact plate 230 has a heart shape divided into two, and when a pair of contact plates 230 are spliced, the heart shape as shown in fig. 10 is formed. The form of the contact plate 230 may be variously changed according to different embodiments.
The contact plate 230 includes a plate body 231 made of a flexible material, a conductive electrode portion 232 provided on a lower side surface of the plate body 231, and a conductive adhesive portion 233 provided on a lower side surface of the conductive electrode portion 232.
The plate body 231 is made of a soft material so as to be bendable into a shape corresponding to a contact portion of a human body. As an example, it may be made of rubber or silicone or cloth material.
The conductive electrode portion 232 is in a wide spread form corresponding to the form of the plate body 231. The conductive electrode portion 232 is energized by contact with the 2 nd bonding terminal portion 220. The material or the form of the conductive electrode portion 232 is not particularly limited as long as the low-frequency current can be uniformly transmitted to the human body.
The conductive adhesive portion 233 is provided on the lower surface of the conductive electrode portion 232, and is used to transmit the low-frequency current transmitted to the conductive electrode portion 232 to the human body by being adhered to the skin of the user.
The conductive adhesive portion 233 of the present embodiment is a conductive hydrogel. The conductive hydrogel is a hydrophilic polymer substance and has very similar characteristics to a biological tissue. Therefore, when the contact plate 230 is brought into contact with the skin by the conductive adhesive portion 233, the same effect as when the conductive electrode portion 232 is brought into direct contact with the skin can be obtained.
Meanwhile, since the conductive adhesive portion 233 composed of the conductive hydrogel is not completely adhered to the skin, it can be easily attached or detached and can be reused as long as it is not contaminated with foreign substances.
A release paper (not shown) is adhered to the lower surface of the conductive adhesive portion 233. The release paper is used to prevent foreign matter from adhering to the adhesion surface of the conductive adhesion portion 233, and is not shown separately because it is used in a similar manner in a conventional low-frequency device.
The contact plate 230 is coupled to the 2 nd coupling terminal portion 220 or the connection sheet member 210, so that the 2 nd coupling terminal portion 220 can be rotated about the rotation center.
A pair of 1 st slits 243 through which the pair of coupling wings 222c can pass are formed at one side of the contact plate 230. The pair of 1 st slits 234 is formed so as to pass through the plate body 231 and the conductive electrode portion 232, whereby the coupling wing 222c inserted into the 1 st slits 234 so as to pass through the 1 st slits 234 comes into contact with the conductive electrode portion 232.
Next, a specific coupling structure of the connection sheet member 210 and the 2 nd coupling terminal portion 220 and the contact plate 230 will be described with reference to fig. 7 to 9.
The attachment/detachment terminal block 221 is disposed so as to be located at the upper portion of the sheet-like member 210 for connection, and the 1 st washer 233 and the contact plate coupling piece 222 are sequentially located at the lower portion of the sheet-like member 210 for connection.
The shaft protrusion 221d of the attachment/detachment terminal block 221 is passed through the 1 st through hole 211 of the connection sheet member 210 and protrudes downward, and the protruding shaft protrusion 221d is passed through the 2 nd through hole 223a of the 1 st washer 223 and the 3 rd through hole 222b of the contact plate coupling piece 222 in this order.
Next, a stopper 221e is formed at the end of the shaft protrusion 221d by pressing the end of the shaft protrusion 221 d. The stopper 221e is formed to prevent the connection sheet member 210, the 1 st washer 223, and the contact plate coupling piece 222 from being separated from the shaft boss 221d of the attachment/detachment terminal block 221.
The contact plate 230 is coupled to the contact plate coupling piece 222. The pair of coupling wings 222c penetrate the pair of 1 st slits 234 formed at one side of the contact plate 230 and the 2 nd slit 224a formed at the 2 nd gasket 224 and protrude downward, and the contact plate 230 and the 2 nd gasket 224 are fixed to the contact plate coupling piece 224 by bending the coupling wings 222c protruding downward in the horizontal direction.
The 2 nd gasket 224 coupled with the contact plate 230 may prevent the 1 st slit 234 of the contact plate 230 from being damaged by the coupling wing 222c, and may ensure that the contact plate 230 may be stably coupled to the contact plate coupling piece 222 by increasing the area where the lower side of the contact plate 230 is supported by the coupling wing 222c.
After the contact plate 230 and the 2 nd gasket 224 are bonded to the contact plate bonding sheet 222, the bonding site can be prevented from being exposed to the outside by attaching the edge sealing tape 225.
The plurality of 2 nd coupling terminal portions 220 are disposed on the connecting sheet member 210 at a constant interval, in the same manner as the plurality of 1 st coupling terminal portions 110 are disposed on the lower side surface of the low frequency generator 100 at a constant interval. Thereby, the contact plate 230 of the conductive plate portion 200 can be easily incorporated into the low frequency generator 100 at one time.
In order to separate the conductive plate portion 200 from the low frequency generator 100, all the 2 nd bonding terminal portions 220 must be separated together from the 1 st bonding terminal portion 110, and thus a state in which the conductive plate portion 200 is very firmly bonded into the low frequency generator 100 can be maintained.
In particular, since the force can be dispersed to all the 2 nd coupling terminal portions 220 by the connecting sheet member 210 even in a state where any one of the plurality of contact plates 230 is subjected to the external force, it is possible to maintain a state where the entire conductive plate portion 200 is firmly coupled to the low frequency generator 100 without causing a case where the specific contact plate 230 subjected to the external force is separated from the low frequency generator 100 alone.
The 1 st coupling terminal portion 110 and the 2 nd coupling terminal portion 220 to which the adjustable low frequency device of the present embodiment is applied can be magnetically coupled by the magnet 112 inserted into the 1 st coupling terminal portion 110.
Since the 2 nd coupling terminal portion 220 is made of a magnetizable metal, magnetic coupling can be achieved by the magnet 112 provided inside the 1 st coupling terminal portion 110 when approaching the 1 st coupling terminal portion 110.
The 1 st coupling terminal part 110 is a structure including a 1 st magnetic coupling plane 110a and a circular insertion groove 110b, and the 2 nd coupling terminal part 220 is a structure including a 2 nd magnetic coupling plane 221a magnetically coupled to the 1 st magnetic coupling plane 110a and an insertion protrusion 221b in the form of a cylinder inserted into the insertion groove 110b.
Thereby, the insertion protrusion 221b can be inserted into the insertion groove 110b and easily coupled to an accurate position only by approaching the 2 nd coupling terminal portion 220 to the 1 st coupling terminal portion 110.
The insertion protrusion 221b inserted into the insertion groove 110b may prevent the 1 st and 2 nd magnetic coupling planes 110a, 221a from sliding in a state where the 1 st and 2 nd coupling terminal portions 110 and 220 are coupled to each other, thereby preventing the coupling position from being distorted.
That is, even if the user makes a drastic movement during the use of attaching the contact plate 230 to the body, the conductive plate portion 200 is not easily separated from the low frequency generator 100.
The contact plate 230 is rotatable together with the 2 nd coupling terminal portion 220 with respect to the connection sheet member 210. Further, the 2 nd coupling terminal part 220 is rotatably coupled to the 1 st coupling terminal part 110 of the low frequency generator 100. Thereby, the posture of the low frequency generator 100 can be easily changed by rotating the contact plate 230 together with the 2 nd coupling terminal portion 220.
The 1 st coupling terminal portion 110 and the 2 nd coupling terminal portion 220 which are magnetically coupled do not cause a decrease in magnetic coupling force even when rotated in a state of being in contact with each other, and thus are not easily separated.
Further, since the connection sheet member 210 can maintain a fixed posture with respect to the low frequency generator 100 by the plurality of 2 nd coupling terminal portions 220, the 2 nd coupling terminal portions 220 are not easily separated from the 1 st coupling terminal portions 110 during a period in which the posture is changed by rotating the contact plate 230.
Further, the two contact plates 230 need to be brought into contact with the skin in a state of being spaced apart from each other, and thus must not interfere with each other. As described above, the contact plate 230 of the present embodiment has a narrower width on one side than the other side, and thus does not interfere with each other even when the two contact plates 230 are rotated to some extent.
When the form of the tunable low-frequency device to which the present embodiment is applied is deformed by rotating the contact plates 230, the two contact plates 230 can be easily attached to a portion where the body is folded or protruded, such as a joint.
In particular, the present utility model can be easily applied to a portion of an existing low frequency device such as a neck, a shoulder, a wrist, an elbow, etc., where it is difficult to attach a contact plate to be fixed in a straight line state, and thus the application range thereof can be greatly expanded as compared with the conventional one.
Accordingly, the present utility model can be applied to various parts of a joint where stimulation is difficult by conventional low frequency devices, such as tendons and ligaments, to relieve pain, or to strengthen specific muscles.
In the present embodiment, a configuration in which a pair of contact plates 230 is provided is illustrated, but this is only one example. In various embodiments, two or more pairs of contact plates 230 may be provided.
In the case where two or more pairs of contact plates 230 are provided, all of the contact plates 230 also need to be rotatably coupled to the sheet-like member for connection 210 through the 2 nd coupling terminal portion 220.
The above description of the present utility model is merely illustrative, and it will be understood by those skilled in the art that the present utility model may be easily modified into other specific forms without changing the technical spirit or essential features thereof.
The embodiments described in the foregoing are, therefore, to be considered in all respects as illustrative and not restrictive. For example, the respective components described as a single type may be implemented in a dispersed manner, and similarly, the components described as a dispersed type may be implemented in a combined manner.
The scope of the present utility model should be defined by the appended claims rather than the foregoing detailed description, and all changes or modifications that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
