The present invention relates to a device for curing rhinitis which uses microcurrent special electromagnetic waves.
Rhinitis is a disease which signifies an inflammation within a nose (in nasal cavity) and is mainly divided into allergic rhinitis and chronic rhinitis. A clear criteria to divide both rhinitis does not exist. It is hard to identify that the rhinitis itself is a fatal illness that threatens life but it is hard to be completely recovered. The rhinitis may be a disease that significantly lowers quality of life.
Actually, in case of allergic rhinitis, a prevalent rate of 10-20% is shown in the West and a prevalent rate of 15% is shown in Korea. A prevalent rate of the allergic rhinitis is gradually increasing due to environmental changes such as air pollution, increased use of food additives, and urbanization. In this regard, it is important to manage the rhinitis in everyday life, to solve the basic cause of the rhinitis by improving living habits, and to relieve symptoms appeared by the rhinitis.
In general, as a rhinitis curing device which is used for the purpose of relieving and curing symptoms of rhinitis, products manufactured by using an ultrasonic spraying method and a compressed air spraying method are widely used, wherein in the ultrasonic spraying method, therapeutic medicine, for example, saline solution, benzethonium chloride, or alcohol, is used to make steam having tiny particles by using ultrasonic waves and the steam is sprayed, and in the compressed air spraying method, steam generated by heating therapeutic medicine or saline solution at a uniform temperature is expanded to eject compressed air and the compressed air is sprayed.
Here, in general, the compressed air spraying method is widely used, since air pressure is used to minutely and strongly spray therapeutic medicine and thereby, treatment effect is excellent compared with the ultrasonic spraying method.
However, in the rhinitis curing devices manufactured by using the ultrasonic spraying method and the compressed air spraying method, an excessive amount of medicine may be consumed at every time of use. Also, the rhinitis curing devices directly spray liquid drug, which is foreign substance, to the affected area within a nose. Accordingly, a stimulus is given to the inside of the nose due to a shock generated during spraying and thereby, other rhinitis diseases may be caused. In this regard, usability is lowered and thus, kids or aged people who relatively have many rhinitis diseases avoid the use of the rhinitis curing devices. In addition, as the rhinitis curing devices need to be placed at a certain spot, there are limitations in their use.
Recently, laser rhinitis curing devices have been developed by low level laser therapy (LLLT) in order to irradiate semiconductor laser to the nasal cavity and to improve allergic rhinitis symptoms by bio-stimulation effect of laser. However, a therapeutic range to which laser is irradiated is narrow due to straightness of laser and thereby, treatment effect is low.
The present invention provides a device for curing rhinitis which provides electromagnetic waves so as to expect rhinitis treatment effect.
The present invention also provides a device for curing rhinitis which uses a driving signal generated by mixing an AC signal with a DC signal so as to increase inflammation management effect.

The curing unit 10 may include an electrode 11 which receives a driving signal Vd from the power equipment 20 and generates an electric field that corresponds to the driving signal Vd.
The electrode 11 may provide an electromagnetic wave based on electric energy of the driving signal Vd, wherein the electromagnetic wave has an electrical influence on a user and thereby, may provide the effects such as pain relief, a decrease in inflammation, and relief from sinus infection through biofilm removal.
When the electrode 11 is disposed in the curing unit 10 in a plural number, at least one electrode 11 from among the plurality of the electrodes 11 may receive the driving signal Vd. Here, an electrode functioning as a ground electrode may be further included in the curing unit 10.
The electrode 11 may be formed of a material including brass, aluminum, conducting polymer, conducting silicon, and stainless steel. However, the present invention is not limited thereto and any material having conductivity may be used as a material for forming an electrode.
The curing unit 10 may include a separate groove or hole formed therein and the electrode 11 may be inserted into the groove or hole. Also, a part of the electrode 11 may be exposed from the curing unit 10. Here, the electrode 11 may not be protruded to the outside of the curing unit 10 or may be protruded to the outside of the curing unit 10.
The power equipment 20 may include a battery 30 and a signal applying unit 40, wherein the signal applying unit 40 may generate the driving signal Vd by using a battery voltage Vb supplied from the battery 30.
In particular, the signal applying unit 40 generates the driving signal Vd by mixing an alternating current (AC) signal with a direct current (DC) signal.
In this regard, the driving signal Vd includes both AC ingredient and DC ingredient and thereby, a synergy effect and resonance created by simultaneously applying the AC ingredient and the DC ingredient are generated. Thus, the removal effect of a biofilm which is the cause of inflammation may be increased.
Referring to
The synergy effect from such AC ingredient and DC ingredient may be identified in
The electric fields by the AC ingredient and the DC ingredient may be simultaneously provided from the electrode 11 according to the driving signal Vd supplied by the signal applying unit 40 according to an embodiment of the present invention and thereby, amplified removal effect for the biofilm may be accomplished.
Also, as described above, the driving signal Vd is set as a form in which an alternating current voltage and a direct current voltage are overlapped. Accordingly, compared with a case where a direct current voltage is only applied, an electric shock hazard to the body and pain caused to the body may be reduced.

The pair of insertion units 10A and 10B may be installed to be combined to and removed from the fixing body 150. In this regard, when the insertion units 10A and 10B and/or the fixing body 150 need to be replaced due to deterioration, a user may easily replace the existing insertion units 10A and 10B and/or fixing body 150 with new insertion units 10A and 10B and/or fixing body 150.
The first insertion unit 10A and the second insertion unit 10B may each be inserted into different nostrils. For example, the first insertion unit 10A may be partially inserted into a right nostril and the second insertion unit 10B may be partially inserted into a left nostril.
The first insertion unit 10A and the second insertion unit 10B may be formed of synthetic resins, wherein the synthetic resins partially contains graphene so as to implement antibiosis, far-infrared radiation release, and water repellency.
The fixing body 150 may include a pair of holes through which the first insertion unit 10A and the second insertion unit 10B penetrate and are inserted.
Also, the fixing body 150 may have an elastic force and thereby, may be formed of an elastic material. For example, when the curing unit 10 is inserted into a user's nose, the fixing body 150 is modified in response to a form of a user's nose and thereby, a gap between the first insertion unit 10A and the second insertion unit 10B may be changed. When the curing unit 10 is removed from a user's nose, the modified fixing body 150 may be restored to an original state.
As illustrated in the drawings, when the curing unit 10 is inserted into a user's nose, in order to facilitate movement of the first insertion unit 10A and the second insertion unit 10B that correspond to a form of a user's nose, a thickness of an area between the first insertion unit 10A and the second insertion unit 10B may be smaller than a thickness of an area where the first insertion unit 10A and the second insertion unit 10B are combined within the fixing body 150.
The first insertion unit 10A and the second insertion unit 10B may each include a head 110 and a body 130.
The head 110 may include a head cover 111 and the electrodes 11, wherein the electrodes 11 may be each disposed in one side surface or both side surfaces of the upper part of the head 110. Also, in order to smoothly provide electromagnetic wave, the electrodes 11 may be further disposed in the upper side surface of the head 110. The electrode 11 may include a first electrode 11A and a second electrode 11B. The first electrode 11A and the second electrode 11B are spaced apart from each other and are disposed in the inside of the head 110. A part of the first electrode 11A and the second electrode 11B may be exposed from the head 110. In this regard, the head 110 may have openings for the first electrode 11A and the second electrode 11B to be partially exposed.
The first electrode 11A and the second electrode 11B may provide electromagnetic wave by the driving signal Vd supplied from the signal applying unit 40.
Here, a gap between the first electrode 11A and the second electrode 11B included in any one insertion unit (for example, the first insertion unit 10A) may be 0.1 mm through 20 mm. When the gap between the first electrode 11A and the second electrode 11B is set to be below 0.1 mm or above 20 mm, the biofilm removal effect by the electromagnetic wave generated from the first electrode 11A and the second electrode 11B may not be expected.
The first electrode 11A and the second electrode 11B may have a size appropriate to be disposed within the head 110 having a size appropriate for users to insert their nostrils. For example, the width of the first electrode 11A recognized by viewing the device 1 for curing rhinitis at the front may be 0.1 mm through 10 mm and the length of the first electrode 11A may be 0.1 mm through 50 mm. Also, the second electrode 11B may be formed to have the same size with that of the first electrode 11A.
Meanwhile, when the width and the length of the first electrode 11A and the second electrode 11B are set to be below 0.1 mm, the management effect on the nasal cavity by an electric field may be lowered.
According to an embodiment of the present invention, the first electrode 11A and the second electrode 11B may be partially protruded from the head 110. In this case, the first electrode 11A may be protruded by a height of 0.1 mm through 15 mm from the surface of the head 110. Here, the second electrode 11B may be set to have the same height with that of the first electrode 11A.
When the height of the first electrode 11A and the second electrode 11B are set be below 0.1 mm, the first electrode 11A and the second electrode 11B may be buried in the inside of the head 110 while an insert injection molding process.
The body 130 may be extended from the head 110 to form a body of the curing unit 10. The body 130 may be designed to have an appropriate length for its use and the end part of the body 130 may be combined to the fixing body 150. The body 130 may be separately formed and combined to the head 110, or the body 130 and the head 110 may be formed as one body.
The body 130 may include a body cover 140 which is combined to the end part of the body 130 and closes the end part of the body 130. At least a part of the body cover 140 may be combined to the fixing body 150. That is, the end part of the body 130 and a part of the body cover 140 are inserted into the hole formed on the fixing body 150 and thereby, may be combined to the fixing body 150.
A first connection line 161 and a second connection line 162 may be partially exposed to the outside through the body cover 140.
As illustrated in
Referring to
Also, the head cover 111 may have an opening 115 for the first electrode 11A and a part of the second electrode 11B to be exposed. One end of the first electrode 11A and one end of the second electrode 11B may all be exposed through one opening 115. Here, the head cover 111 may include a pair of openings 115 which face each other so that the first electrode 11A and the second electrode 11B may be exposed to the both sides of the head 110.
In addition, the head cover 111 may include an opening on the upper surface thereof so that the first electrode 11A and the second electrode 11B may be exposed to the upper surface of the head 110.

In this case, the pair of first openings 117A may be formed to face each other and the pair of second openings 117B may be also formed to be face each other.

Here, the center area of the first electrode 11A may be connected to one end of a first connection electrode 131 which will be described below.

The second electrode 11B is formed as in the same form as the first electrode 11A and includes the first end part 112B and the second end part 113B located in the opposite direction, wherein the first end part 112B and the second end part 113B may be exposed to the pair of second openings 117B included in the head 110. Also, the second electrode 11B may be interposed between the first end part 112B and the second end part 113B and may include the third end part 114B exposed to the fourth opening 117D included in the head 110.
That is, at least a part of the first electrode 11A and the second electrode 11B may have a ‘T’ shape.
Next, the body 130 may include the first connection electrode 131 and a second connection electrode 132 arranged therein to transmit the driving signal Vd.
The first connection electrode 131 and the second connection electrode 132 may be respectively connected to the first electrode 11A and the second electrode 11B. More specifically, one end of the first connection electrode 131 may be connected to the center area of the first electrode 11A and one end of the second connection electrode 132 may be connected to the center area of the second electrode 11B.
Also, in order to receive power from the power equipment 20, the first connection electrode 131 and the second connection electrode 132 are extended long toward the end part of the body 130 and thereby, may be electrically connected to a first connection terminal 151 and a second connection terminal 152 disposed in the body cover 140. Specifically, the end part of the first connection electrode 131 may be connected to the first connection terminal 151 and the end part of the second connection electrode 132 may be connected to the second connection terminal 152.
For convenience of the manufacture, the first connection electrode 131 and the first electrode 11A may be formed as one body and the second connection electrode 132 and the second electrode 11B may be formed as one body.
Also, the first connection electrode 131 and the second connection electrode 132 may be formed of a material that is same as that of the electrodes described above.
In the body cover 140, the first connection terminal 151 and the second connection terminal 152 may be respectively connected to the first connection line 161 and the second connection line 162, wherein the first connection line 161 and the second connection line 162 may be partially exposed to the outside of the body cover 140.
The body cover 140 may include a pillar unit 170, wherein the pillar unit 170 may be disposed at the center of the body cover 140 and disposed between the end part of the first connection electrode 131 and the end part of the second connection electrode 132.
The pillar unit 170 may function as a spacer in such a way that the first connection electrode 131 and the second connection electrode 132 are spaced apart from each other by the pillar unit 170 and are prevented from contacting and being electrically connected to each other.

The first display unit 21 may display the charge state of a battery disposed within the power equipment 20. For example, the first display unit 21 may include Light-Emitting Diode (LED) and may radiate a number of colors showing the charge state (for example, red) and the full-charge state (for example, blue).
The second display unit 22 may display the operating time of the device 1 for curing rhinitis. For example, the second display unit 22 may include LED and radiate a number of colors displaying 15 minute operation (for example, green) and 30 minute operation (for example, yellow).
The switch 23 may control power on/off of the device 1 for curing rhinitis and may be used to set the operating time.
The charging terminal 25 may be used to charge the battery disposed within the power equipment 20.
Meanwhile, in the power equipment 20, the cable 60 may be connected to an output terminal used to supply the driving signal and to combine with the curing unit 10. The output terminal may be electrically connected to the first connection line 161 and the second connection line 162.
The power equipment 20 may generate a driving signal by using a battery voltage supplied from the battery disposed therein and may supply the generated driving signal to the electrodes 11A and 11B through the first connection line 161 and the second connection line 162 connected to the output terminal.
Referring to
The battery 30 included within the power equipment 20 may supply the battery voltage Vb to the signal applying unit 40.
For example, the battery 30 may be set as a primary battery or a secondary battery.
When the battery 30 is a primary battery, a user may periodically replace the battery 30. When the battery 30 is a secondary battery, charging may be accomplished through various charging methods. For example, wired charging may be accomplished through the charging terminal 25 described above or wireless charging may be also accomplished.
Next, the signal applying unit 40 according to an embodiment of the present invention may include a DC-DC converter 41, a signal generating unit 42, a filter 43, and a calibration unit 44. In addition, a voltage distribution unit 45 may be further included.
The DC-DC converter 41 may receive the battery voltage Vb from the battery 30, may convert the battery voltage Vb into an output voltage Vo in a predetermined level, and may output the output voltage Vo.
The signal generating unit 42 operates based on a voltage supplied from the DC-DC converter 41 and may generate an AC signal Sac having a predetermined frequency by using the output voltage Vo of the DC-DC converter 41.
The signal generating unit 42 may be embodied by using a well-known component such as an oscillator and a function generator which may generate the AC signal.
For example, the AC signal Sac may be set to have a frequency of 1 KHz through 1000 MHz. When the AC signal Sac is set to have a low frequency of below 1 KHz, the inflammation relief effect through biofilm removal is decreased. When the AC signal Sac is set to have a super-high frequency of above 1000 MHz, the biofilm removal effect is also decreased. Meanwhile, the frequency of the AC signal Sac may be set to 5 MHz through 15 MHz which is appropriate to remove a biofilm.
Also, an amplitude of the Ac signal Sac may be set to 0.1 mv through 3V. When the amplitude of the Ac signal Sac is below 0.1 mV, the biofilm removal effect may not be expected. When the amplitude of the Ac signal Sac is above 3V, toxic substances may be generated due to electrolysis of body fluids.
The filter 43 may perform a filtering process for the AC signal Sac generated by the signal generating unit 42. For example, the filter 43 may include a low pass filter and may convert the AC signal Sac in a sawtooth wave form into the AC signal Sac′ in a sine wave form. However, the type of the filter 43 is not particularly restricted thereto and various types of filter may be employed according to a designed structure.
The calibration unit 44 may mix the AC signal Sac′ supplied through the filter 43 with the DC signal Sdc to generate the driving signal Vd. For example, the calibration unit 44 may be embodied as an operating amplifier which may add (or overlap) the AC signal Sac′ and the DC signal Sdc, however, the present invention is not limited thereto.
In this regard, offset that corresponds to the DC signal Sdc is generated in the Ac signal Sac′ and thereby, the driving signal Vd having both AC component and DC component may be generated.
Since the driving signal Vd includes all characteristics of the AC signal Sac, the driving signal Vd may be set to have a frequency of 1 KHz through 1000 MHz and may be also set to have a frequency of 5 MHz through 15 MHz, which is more appropriate to remove the biofilm. In addition, an amplitude of the driving signal Vd may be set to 0.1 mv through 3V.
Referring to
Here, a voltage value of the DC signal Sdc may be set to above the amplitude of the AC signal Sac′. Accordingly, the voltage value of the driving signal Vd may be set to be above 0.
Finally, a DC offset value of the driving signal Vd may be the same as or greater than the amplitude of the driving signal Vd.
When the DC offset value of the driving signal Vd is below the amplitude of the driving signal Vd, a section where the driving signal Vd has a negative value is generated. Here, since the voltage has a negative value in the section, a loss of electric energy may occur.
However, as in an embodiment of the present invention, when the DC offset value of the driving signal Vd is set to be the same as or greater than the amplitude of the driving signal Vd, the voltage of the driving signal Vd is always above 0 and thereby, a loss of electric energy may be minimized.
Meanwhile, the DC signal Sdc may be generated by the voltage distribution unit 45. For example, the voltage distribution unit 45 may receive the output voltage Vo from the DC-DC converter 41 and may perform voltage distribution for the output voltage Vo so as to generate the DC signal Sdc.
The voltage distribution unit 45 may include a resistant string for distributing the output voltage Vo, however, is not restricted thereto.
When the output voltage Vo of the DC-DC converter 41 is appropriate to be immediately used to generate the driving signal Vd, the corresponding output voltage Vo may take a role of the DC signal Sdc. In this case, the voltage distribution unit 45 may be omitted and the output voltage Vo of the DC-DC converter 41 may be input to the calibration unit 44.
Referring to
For example, the characteristics of the driving signal Vd may include the amplitude of the driving signal Vd and the DC offset.
That is, users may control at least one of the amplitude of the driving signal Vd and the DC offset and thereby, may set optimal driving signal Vd that is appropriate to users. According to such function, customized rhinitis curing, in which users' characteristics are considered, may be available.
Here, users' input for controlling the characteristics of the driving signal Vd may be performed by the switch 23 installed in the power equipment 20 or a separate button (not illustrated) and users control the switch 23 installed in the power equipment 20 so as to control or set the characteristics of the driving signal Vd.
When setting information of the driving signal Vd is input by operating the switch from the user, the control unit 50 may control the signal applying unit 40 so that the driving signal Vd has the amplitude and the DC offset value that correspond to the input setting information.
The control unit 50 controls the signal generating unit 42 and thereby, may change the amplitude of the AC signal Sac. Also, the control unit 50 controls the DC-DC converter 41 and/or the voltage distribution unit 45 and thereby, may control the voltage value of the DC signal Sdc. Accordingly, characteristics of the driving signal Vd may be finally changed.
Here, the control unit 50 may control the voltage distribution unit 45 for the voltage value of the DC signal Sdc to be set above the amplitude of the AC signal Sac′ and thereby, the voltage value of the driving signal Vd may be set to be above 0.
Meanwhile, according to an embodiment of the present invention, characteristics of the driving signal Vd supplied to the first insertion unit 10A and characteristics of the driving signal Vd supplied to the second insertion unit 10B may be set to be same as each other. That is, one driving signal Vd output from the signal applying unit 40 may be input to the first insertion unit 10A and the second insertion unit 10B.
According to another embodiment of the present invention, characteristics of the driving signal Vd supplied to the first insertion unit 10A and characteristics of the driving signal Vd supplied to the second insertion unit 10B may be set to be different from each other.
