Description

LOW FREQUENCY GENERATING POULTICE
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention relates to a low frequency generating poultice (including patch type, cataplasm type, plaster type, puff type and the like), and more particularly to a low frequency generating poultice adapted to be attached to skin where bruise, myalgia, arthritis or neuralgia is developed to increase penetration efficiency of the medication to hypodermal tissues according to low frequency effect for quick treatment of pain and further increase medicinal effect according to physical frequency vibration.
DESCRIPTION OF THE PRIOR ART
Generally, a poultice (including patch type, cataplasm type, plaster type, puff type and the like) is made of fabric where on side thereof applied with adhesive medication is attached with a release sheet of vinyl property for protection of medication and release in use. The poultice and the release paper are soft materialwise and are attachable to skins with resilience.
The poultice, deprived of the release paper, is applied to skin of pain for a certain period of time, where continuous permeation of medication and action thereof relieve the pain.
However, there is a problem in the poultice according to the prior art in that physical treatment is not provided to the pain and the pain is treated only by medicinal action of applied medication, such that treatment effect is decreased with permeability of medication dropping in time to thereby necessitate change for a new poultice for continued treatment. There is another problem in that skin pores are closed to cause pruritus on the diseased part when medication-reduced poultice is kept applied thereon for a period longer than is necessary, thereby inconveniencing a user and providing no means of ascertaining the medicinal duration of the poultice.
There is a case where, as a physical treatment method in a hospital for increasing the treatment effect on the affected part, a medication is applied directly to the diseased part and a separate low frequency generator is put onto the medication-applied part. There is a problem in the method however in that economic burdon is laden with a patient due to expensive equipment and a self treatment using the generator cannot be carried out.
Meanwhile, there is a spray gun-typed medicated atomizer containing a liquid medication therein and having a treatment function similar to that of poultice. The atomizer is used for treatment by pressing a button thereon for spraying medication to an affected part. There is however a problem in that it is inconvenient to use and medicinal effect is inferior to poultice in terms of duration thereof.
There arises a necessity of simplifying treatment and concurrently maximizing treatment effect in consideration of the fact that most of the muscle or arthralgia patients widely use the poultice (patch type, cataplasm type, plaster type, puff type included).
To overcome the afore-mentioned problems according to the prior arts, the present applicant has disclosed a low frequency generating poultice under Korean patent registration no. 245836 and Japanese registration no. 2911876.
The low frequency generating poultice 1, being separated in a plurality of pieces as illustrated in Figures 1, 2 and 3, includes poultice sheets 5a and
5b containing medication where the poultice sheets 5a and 5b are attached at one side thereof with a contact fabric 4 and conduction plates 8a and 8b are engaged in between the poultice sheets 5a and 5b and the contact fabric 4.
Furthermore, the conduction plates 8a and 8b are mutually separable relative to the poultice sheets 5a and 5b and maintain an attached state to an upper surface of the poultice sheets 5a and 5b. The poultice 1 also includes a low frequency generator 6 having a manipulating button 12, anode and cathode terminals 7a and 7b and a battery (not shown) where the anode and cathode terminals 7a and 7b are respectively connected to the conduction plates 8a and 8b. The low frequency generator 6 is so constructed as to be coupled in between the poultice sheets 5a and 5b.
In other words, a predetermined size of place is arranged at the poultice sheets 5a and 5b to allow the low frequency generator 6 to be positioned in between the poultice sheets 5a and 5b and terminal holes 9a and 9b are formed at the conduction plates 8a and 8b to couple the anode and cathode terminals 7a and 7b of the generator 6. In order to enjoin the terminals 7a and 7b from being detached and deviated from the holes 9a and 9b, the terminals 7a and 7b are formed thereunder with protruders 11 connectible to the poultice sheets 5a and 5b.
The poultice sheets 5a and 5b are attached at medicated surface thereof with a vinyl release sheet for protection of the medicated surface and separation in use. The contact fabric 4 is formed with button holes 2a and 2b to expose the manipulating button 12 and an up/down button 13 of the low frequency generator 6.
The contact fabric 4 is so made as to have a larger circumference than that of poultice sheets 5a and 5b combined and is formed at one circumferential surface thereof with a contact layer contacting a sore point and release sheets 3a and 3b for protection of the contact layer to there constitute the poulice 1.
In the absence of the contact fabric 4, the poultice sheets 5a and 5b themselves come to have a tendency of stickiness to be directly attached to the sore point.
However, there is a problem in the low frequency generating poultice 1 thus constructed according to the prior art in that the conduction plates 8a and 8b are interposed in between the contact fabric 4 and the poultice sheets 5a and 5b and the conduction sheets 8a and 8b are integrally formed at one side thereof with the low frequency generator 6, such that the low frequency generator 6 relatively higher in price thereof than the poultice sheets 5a and 5b cannot be separated for reuse. There is another problem in that use of the conduction plates 8a and 8b tends to increase the manufacturing cost of the poultice 1, making it next to impossible to commonly use the current poultice attached with the low frequency generator 6.
There is still another problem in that the conduction plates 8a and 8b connected to the anode and cathode terminals 7a and 7b protruded to both sides of the low frequency generator 6 are separably manufactured along with the poultice sheets 5a and 5b to complicate the manufacturing process.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, beginning with first embodiment referring to Figures 4 through 6b.
<First Embodiment
As illustrating in Figures 4 and 5, the poultice 50 according to the present invention includes a poultice sheet 52 containing medication and centrally formed with a through hole 52a, a vinyl release sheet 54 attached underneath the medicated surface (bottom surface) of the poultice sheet 52 for protection of the medication, releasable in use, and formed with a through hole 54a, a contact fabric 56 having a larger circumference than that of the poultice sheet 52 and releaseably adhered to a non-medicated surface (upper surface) while a tip end of the circumference touches the pained part of a user, and a low frequency generator 58 coupled to or separated from the through holes 52a and 54a respectively formed at the poultice sheet 52 and the release sheet 54 in a state of being integrally secured to a central bottom surface of the contact fabric 56 and changed into various vibration modes in operation to generate low frequency.
The through holes 52a and 54a are formed at each inner side thereof with slits 52b and 54b each at an opposite side for enlarging or shrinking the size of the through holes 52a and 54a such that the low frequency generator 58 can be easily inserted into the poultice sheet 52 and the release sheet 54. The contact fabric 56 is only used for the same kind of product and can be adhered to an affected part according to an adhesion property of the poultice sheet 52. The contact fabric 56 is centrally formed at a predetermined position thereof with button holes 56a and 56b and a lamp hole 56 through which an on/off button (described later), an up/down button and a signal unit (alarm or lamp) of the low frequency generator 58 can be exposed outside, and is attached at both left and right bottom surfaces thereof with release sheets 60a and 60b to form contact layers for contact with the effected part of the user and to protect the contact layers.
The low frequency generator 58 is installed at an upper surface of a body 58a thereof with an on/off button 58b, an up/down button 58c and a signal unit 58d, each at a predetermined space, and the body 58a is mounted therein with a battery and electronic parts (not shown). Furthermore, the on/off button 58b and the up/down button 58c may be constructed in one button.
The body 58a is protrusively formed thereunder with a thin-plated printed circuit board PCB 58e having a larger circumference than that of the body 58a, and the PCB 58e is internally mounted at an upper peripheral side thereof with a cathode terminal 58f which directly contacts the medicated surface of the poultice sheet 52 when the poultice sheet 52 is used.
The PCB 58e is also internally mounted at a central bottom surface thereof with an anode terminal 58g which directly contacts an affected part (skin) of a user.
At this time, the PCB 58e is larger in its circumference than each inner diamer of the through holes 52 and 54a such that each through hole 52a and 54a can be enlarged or shrunken by the slits 52b and 54b formed at sides thereof for the PCB 58e to pass therethrough easily.
Next, operational effect of the first embodiment thus constructed according to the present invention will be described.
In order to use the poultice 50, first of all, the low frequency generator
58 is inserted into the through holes 52a and 54a formed at the poultice sheet 52 and the release sheet 54, and as illustrated in Figure 6a, release sheets 54, 60a and 60b attached under both left and right bottom surfaces of the contact fabric 56 and under the poultice sheet 52 are respectively separated, and then the poultice sheet 52, as illustrated in Figure 6b, is softly adhered to an affected part (B) of a user to press an outer surface and a marginal side of the contact fabric 56.
At this time, the poultice sheet 52 is attached to the affected part (B) by adhesive component coated on the medicated surface located thereunder, and the contact fabric 56 is attached to the affected part (B) by a contact layer coated at a marginal bottom surface thereof to allow the attached state of the poultice 50 to be securely maintained.
Successively, as illustrated in Figure 6b, the on/off button 56b exposed to the surface through button hole 56a of the contact fabric 56 is pressed to operate ON and the up/down button 58c exposed to the surface through the button hole 56b of the contact fabric 56 is pressed to select the vibration mode.
The vibration mode is so circuitally constructed as to be changed into at least more than five steps, such that when a user presses the up/down button 58c, a desired section of vibration mode can be selectively adjusted.
When the low frequency is generated according to the operation of the low frequency generator 58, the low frequency penetrates the hypoderm to carry the medicated component emitted from the poultice sheet 52 into the affected part evenly and deeply.
In other words, the cathode terminal 58f of the PCB 58e mounted underneath the low frequency generator 58 contacts the poultice sheet 52 while the anode terminal 58g of the PCB 58e touches the affected part (B) to allow the current to flow therein, such that, when the on/off button 58b is pressed to activate the low frequency generator 58, low frequency cathode component transmitted to the affected part (B) through the poultice sheet 52 from the cathode terminal 58f and low frequency anode component transmitted to the affected part (B) from the anode terminal 58g are electrically cooperated to vitalize the medical action of the low frequency while the medicated component of the poultice sheet 52 at the cathode terminal 58f moves to the anode terminal 58g through the pained part (B) to facilitate penetration of the medicated component.
As mentioned above, medicated component from the poultice sheet S2 and another medicated component from direct current generated from the low frequency simultaneously penetrate the subcutaneous tissue to vitalize the medicated action, where, low frequency vibration (in other words, physical therapentic action) provides a quicker relief to pain of the affected part (B) for earlier recovery.
Meanwhile, a battery in the low frequency generator 58 is capacitated enough to enable to change poultice sheets 52 in every predetermined period of time, such that, when the medicated component of the poultice 50 is detached from the affected part (B), where only the poultice sheet 52 deprived of the medicated component is separated from a combined body of contact sheet 56 and the low frequency generator 58 for disposed.
Successively, as illustrated in Figures 4 and 5, a new poultice sheet 52 is substituted for an old poultice sheet 52. In other words, the low frequency generator 58 secured underneath the contact fabric 56 is inserted into the through holes 52a and 54a formed at the poultice sheet 52 and the release sheet 54 and simultaneously non-medicated surface of the poultice sheet 52 is made to get adhered to a bottom surface of the contact fabric 56 while the non-medicated surface of the poultice sheet 52 faces upward and the poultice sheet 52 is still attached with the release sheet 54. At this time, the through holes 52a and 54a are enlarged in sizes thereof by the slits 52b and 54b formed at sides thereof when the PCB 58e mounted underneath the low frequency generator 58 passes through but are shrunken in sizes thereof by the slits 52b and 54b to correspondingly assort with circumference of the body 58a at the upper end of the low frequency generator 58 after the PCB 58e passes therethrough.
Consequently, manufacturing cost can be reduced to increase economy by mass-producing the contact fabric 56 and the low frequency generator 58 in fixed reuseable integral form and preparing several sheets of poultice sheets 52 attached with release sheets 54 to allow replacement thereof whenever efficacy of the medicated component becomes ineffective.
<Second Embodiment
Although the above description has been described in detail with reference to the first embodiment of poultice 50 where only several poultice sheets 52 are replaced for use when the low frequency generator 58 is integrally secured to the contact fabric 56, it is not to be taken as limiting. Still other variations and modifications are possible.
By way of example, as illustrated in Figure 7 as a second embodiment, several poultice comprising contact sheets 56 and poultice sheets 52 are prepared to construct a poultice 50a with only the low frequency generator 58 attached or detached through holes 52a of the poultice sheet 52.
Furthermore, through holes 52a and 54a respectively formed at the poultice sheets 52 and release sheets 54 are not completely drilled but sites corresponding thereto are pre-formed on the poultice sheets 52 and release sheets 54, where portions of the poultice sheets 52 and the release 54 of the site are not completely removed for mass-production. <Third Embodiment
Now, a third embodiment of the present invention is described in detail with reference to Figures 8 through 11.
The low frequency generator 90 according to the third embodiment of the present invention is attached into or detached from a marginal portion of poultice 80 by way of clip closure, where the poultice 80 is layered by contact fabric 81, poultice sheet 82 and release sheet 83 in that order.
In other words, the low frequency generator 90 is respectively installed at an upper surface of a body 91 thereof with an on/off button 92, an up/down button 93 and a signal unit 94, each spaced at a predetermined distance and the body 91 is internally mounted with a battery 95, a control element 96 and the like.
The body 91 is mounted thereunder with a thin plate-shaped printed circuit board PCB 98 having a lower clip portion 97 adhered to a bottom surface of the body 91 and horizontally, integrally extended at one end thereof.
The lower clip portion 97 is insertedly mounted at an upper surface thereof with a first terminal directly contacting the medicated surface of the poultice sheet 82 when the poultice 80 is used, and the PCB 98 is insertedly mounted at a lower central surface thereof with a second terminal 100 directly contacting the affect part (skin) of a user.
The body 91 is mounted at a lateral position thereof with an upper clip portion 101 located at a height corresponding to that of the lower clip portion
97, being distanced at a predetermined space to contact an upper lateral surface of the poultice sheet 82. The battery 95 may be so constructed as to be inseparable within the body 91 or replaceable from the body 91. The second terminal 100 is made of soft conductible material in order not to give a negative feeling to the human body.
The first terminal 99 and the second terminal 100 may be constructed either as a positive pole and a negative pole respectively or a negative pole and a positive pole respectively according to design variation.
The upper clip portion 101 is centrally and integrally formed with, by way of example, a V-shaped bent resilient unit 101a to eliminate a looseness when the poultice sheet 82 is inserted into a space between the upper clip portion 101 and the lower clip portion 97. The low frequency generator 90 may be constructed to use an insertion hole formed at a predetermined position of the poultice sheet 82.
Now, operational effect of the third embodiment of the present invention thus constructed will be described. Throughout the description, like operational effect as in the first embodiment of the present invention will be omitted.
In other to assemble a separably marketed poultice 80 and a low frequency generator 90 as shown in Figure 8 for use in an assembled manner as shown in Figure 5, the release sheet 83 attached underneath the poultice sheet 82 is detached and a marginal portion of the poultice sheet 82 is inserted into a gap formed between the upper clip portion 101 integrally protruded at a lateral surface of the body 91 of the low frequency generator 90 and the lower clip portion 97 to allow a bottom surface of the upper clip portion 101 and an upper surface of the poultice sheet 82 to respectively touch the upper and bottom surfaces of the poultice sheet 82.
At this time, the upper clip portion 101, being formed at a lengthwise central end thereof with the resilient unit 101a, is pressurized by resilience of the resilient unit 101a when the upper clip portion 101 adheres to an upper lateral end of the poultice sheet 82, while the lower clip portion 97 tightly contacts a bottom lateral end of the poultice sheet 82 according to resilience of the resilient unit 101a to cause the first terminal 99 mounted thereon to securely touch the bottom surface of poultice sheet 82.
When the poultice sheet 82 and the low frequency generator 90 are completed in assembly thereof, the poultice sheet 82 is lightly adhered to the affected part (B) and simultaneously the contact fabric 81 is attached to the affected part (B) to cover the poultice sheet 82 and the low frequency generator 90, maintaining a solid attachment state of the poultice sheet 82 and the low frequency generator 90. For a poultice which does not use a contact fabric 81, only the adhesive property of the poultice sheet 82 is used for attaching the same.
Successively, the low frequency generator 90 is enactivated to perform automatic repetitive operations where a frequency vibration operation is performed for a predetermined time (10 minutes), and when the frequency vibration operation is done, a continuous direct current is applied without frequency vibration for 45 to 60 minutes to allow the medicated component to penetrate the affected part (B), and again the frequency vibration is performed for 10 to 15 minutes.
In other words, the poultice 80 and the low frequency generator 90 are made to be separably assembled to enable the poultice 80 to be used as a disposable item while the low frequency generator 90 is used as a reuseable item, such that any poultice 80 available in the market can be applicably used, and one low frequency generator 90 can reuse a plurality of poultice 80 where the low frequency is applied to the poultice 80 to help cure the affected part (skin). As apparent from the foregoing, there is an advantage in the low frequency generating poultice thus described according to the present invention in that a plurality of poultice sheets can be substitutively used on one low frequency generating poultice and construction is so improved as to allow a positive terminal of a low frequency generator to contact the poultice sheet and a negative terminal to touch an affected part of a user for current to flow therebetween, thereby eliminating inconvenience and cumbersomeness of separably producing the poultice sheet and a conductor plate according to the positive pole and the negative pole to simplify the manufacturing process, providing convenience in use and reducing manufacturing cost as well.
There is another advantage in that the low frequency generating poultice according to the present invention is so constructed as to enable use of a clip at one side thereof in a releaseably fashion, thereby eliminating a need of specially producing the poultice but providing a convenience of accommodating all types of poultices widely-used in the market. There is still another advantage in that one low frequency generator can be economically used for a plurality of poultices, providing a low frequency reaction to the poultice for assistance in treatment of affected part of a user.
