Portable Digital Low Frequency Therapy-Apparatus

The present invention relates to a portable digital low-frequency therapy device, and particularly, a portable digital low-frequency therapy device that is slim and easy to carry and that enables various functions easily by changing the probe structure.

In general, the conventional portable low frequency treatment devices used an analog method, and may be exemplified by Korean Utility Model Registration No. 0281926.

Conventional portable low frequency treatment devices are provided with a plurality of operation buttons to treat the treatment site by the user arbitrarily manipulated, there is a problem that a user who is not familiar with the use of the treatment time or treatment method mistake the side effects.

An example of such a conventional low frequency treatment device will be described in detail with reference to a conventional portable low frequency treatment device with reference to the contents described in Utility Model Registration No. 0281926.

1A and 1B are a plan view and a side view, respectively, of a conventional portable low frequency therapy device, with reference numeral 21 denote an electric stimulator body, reference numerals 22a, 22b, and 22c, respectively, various types of massage balls, reference numeral 23, a battery cover, and reference numeral 24, respectively.

FIG. 2 is a circuit diagram of a conventional portable low frequency treatment device, and the operation of the conventional low frequency treatment device will be described with reference to FIGS. 1A, 1B, and 2.

In the main body 21, an electronic circuit is disposed inside, a metallic coating is coated on the outside, and a plurality of switches SW1, SW2, and SW3 are disposed. In addition, when the metallic film of the case of the main body 21 is a conductor, an electric current flows through a palm or a finger when held by a hand. The electrical current applied to the treatment site is applied to the treatment site through the massage balls 22a, 22b and 22c, flows by hand through the inside of the human body, and then converges to the case of the body 21.

The massage balls 22a, 22b, and 22c are made of a conductor so that current flows well as a part that contacts the body part to be treated, and is placed in front of the main body 21 to directly apply an electric pulse voltage.

Here, the massage ball (22a, 22b, 22c) can be manufactured in various sizes and shapes of the diameter of the ball to be used to change the size and shape according to the treatment site of the body.

3 is a perspective view of a portable low frequency therapy device having a spherical massage ball having a small diameter according to a first embodiment of the conventional portable low frequency therapy device. Figure 4 is a perspective view of a portable electric stimulator having a large diameter circular massage ball according to a second embodiment of a conventional portable low frequency therapy device. 5 is a perspective view of a portable electric stimulator having a pointed probe massage ball according to a third embodiment of a conventional portable low frequency therapy device.

3 to 5, the massage balls (22a, 22b, 22c) produced in various sizes and shapes are removable and mounted to each other (see Figure 2b), the massage balls (22a, 22b, 22c) The small diameter may be a spherical massage ball 22a (see FIG. 3), a large diameter circular massage ball 22b (see FIG. 4), or a pointed tip 22c (see FIG. 5). That is, the pointed tip 22c with a pointed tip may be mounted in a small diameter massage ball 22a, and the rounded tip with a small diameter 22a may be mounted with a pointed tip 22c. The massage ball 22b can be mounted and detached together, so that portability is convenient.

The battery cover 23 is connected to the same electrode as the case of the main body 21 as a conductor. The battery cover 23 may be opened and closed by rotating by a screw tab to replace a battery located inside the main body 21, and the battery cover 23 is the same as the case of the main body 21. It becomes an electrode, it is characterized by minimizing the electrical resistance between the palm and the case of the body 21 by widening the contact area of the gripping palm. This minimizes the electrical sensation felt in the palm of the hand when the current flows.

The insulating ring 24 is made of a plastic insulator, and is inserted to completely insulate the electrodes of the body 21 case and the electrode terminals of the massage balls 22a, 22b, and 22c having different polarities.

The conduction ring 25 is made of metal and is inserted such that the case of the main body 21 and the battery cover 23 become one electrode.

The power switch SW1 26 is used to turn on / off power supplied from a battery built in the main body 21, and a slide switch may be used.

The output volume adjuster VR1 29 may be manually rotated to adjust the magnitude of the pulse voltage output to the massage balls 22a, 22b, and 22c.

In addition, the light emitting device (LED) 27 emits light at regular intervals when the power switch (SW1) 26 is turned on, indicating that the power switch (SW1) 26 is turned on. When the power switch SW1 is turned off, the light emitting device LED 27 is also turned off. The light emitting element 27 is disposed at the front part.

Graduation window 28 is disposed above the output volume regulator VR1 29 when adjusting the magnitude of the output voltage with the output volume regulator VR1; Will be displayed as.

In addition, the electrode conversion switch SW3 30 converts the polarities of the output pulses output to the massage balls 22a, 22b, and 22c into positive (+) polarities or negative (-) polarities, so that the directions of the electric currents are mutually different. Make it the opposite. Here, when the electrode conversion switch (SW3) 30 is selected to be positive, the current flows in the order of the massage balls (22a, 22b, 22c)-treatment area-inside the body-hand-body 21, minus (-) When selected as the main body 21-hand-the inside of the body-treatment site-massage ball (22a, 22b, 22c) in the order of the current flows.

The intensity selection switch SW2 31 selects the intensity of the pulse output voltage output to the massage balls 22a, 22b, and 22c. In the case of a normal stimulus, it is set to low and relatively low output level. However, it is desirable to set it to high only when a particularly strong magnetic pole is required to maintain a relatively high output level.

Referring to the specific operation of the conventional portable low frequency treatment device, a low voltage pulse using a 3 volt (Vin) battery (Vin) and a small transformer (T1) through a voltage of 300 ~ 400 volts (volt) to a certain voltage Make a high voltage pulse with a period.

The output volume corresponding to the magnitude of this high voltage is adjusted with a finger, and the magnitude of the output can be continuously finely adjusted while visually seeing the number written in the scale window 28. One of these high voltage pulses is applied to the massage balls 22a, 22b and 22c and the other is connected to the case surface of the body 21. When holding the main body by hand and touching the treatment area with the massage balls 22a, 22b, 22c, a current flow loop is formed through the human body, and the current flows in one direction according to the selection of the output polarity.

In addition, an electrode conversion switch 30 (SW3) is provided to select and use the direction of the current according to the treatment area of the human body. That is, when the polarity of the electrode conversion switch 30 is selected to be positive (+), the current flows in the order of the massage balls 22a, 22b, 22c-the treatment area-the inside of the human body-the body 21, and the electrode conversion switch ( If negative (-) is selected 30, it flows in the order of the body 21-the hand-the inside of the body-the treatment area-massage ball (22a, 22b, 22c) in the opposite direction. However, if the intensity of the current flowing is large, you can feel the exhilarating electrical sensation between the main body and the hand, and the exhilarating electrical sensation can be felt even in the body part in contact with the massage balls 22a, 22b, and 22c. There may be a feeling of discomfort or rejection. In this way, a weakness selector switch (SW2; 31) is provided to select the output at a low level, which is not sensed for beginners. Even if it feels a little bit of sensation, I chose to use a large output level.

In order to minimize the electrical sensation, the contact surface is widened to reduce the electrical resistance. For this, most of the case of the main body and the battery cover 23, which are held by the palm and fingers, are also used with a conductor. In particular, when the battery cover 23 is in contact with the soft part of the palm, the electrical resistance is low and there is no electrical feeling.

Referring back to Figure 3, the circuit operation of the conventional portable low-frequency treatment device will be described in detail as follows.

First, when the power switch SW1 is turned on, power is applied to the pulse generating circuit PG1, and the light of the light emitting diode LED is switched according to a pulse period to periodically turn on the transistor TR1 while operating the transistor TR1. Turned on / off. The pulse waveform of the magnitude of the battery voltage Vin generated in the pulse generating circuit PG1 is changed into a high voltage pulse waveform in the boosting transformer T1. The high voltage pulse waveform is selected when the weak select switch SW2 is opened, and a voltage drop occurs in the resistor R1 to lower the high voltage, thereby outputting a low pulse waveform. On the contrary, when the strength selection switch SW2 is closed, the strength is selected and the high voltage pulse waveform is transmitted to the output side without any voltage drop. The intensity of the output is gradually adjusted according to the rotation angle of the output volume controller VR1, which is output by the strength and weakness selection switch SW2.

One of the two output pulse terminals is connected to the massage balls (22a, 22b, 22c) and the other is connected to the body 21 case. At this time, when the polarity change switch (SW3) is operated, the polarity of the output pulse voltage is changed, and accordingly, the polarity of the voltage applied to the massage balls 22a, 22b and 22c and the main body 21 case is also changed. The flow chart will change.

Conventional portable low-frequency therapy device is also possible to point acupuncture points (22c) to find and stimulate acupuncture points, but instead of using a round and wide massage ball (22b) to massage as easy as massage the entire treatment area.

In addition, instead of the grounding plate attached to a part of the main body case surface, the whole main body case becomes one grounding plate, that is, one electrode, thereby widening the area of the finger and the palm contacting the conductors of the main body case. The electrical resistance between them is reduced to minimize the electrical sensation felt in the case when current flows.

6A and 6B are a plan view and a perspective view, respectively, of an internal structure of a conventional portable low frequency therapy device, with reference numeral 34 designating a circuit board, 35 designating a transistor TR, and 36 designating a battery, respectively. As shown in FIGS. 6A and 6B, the transistors TR and 35 of FIG. 2 are mounted on the circuit board 34. The structures of the insulating ring 24 and the conduction ring 25 and the like are shown. It is shown. In addition, as described above, the probe-type massage ball 22c may be mounted in the spherical massage ball 22a having a small diameter, and the probe-type massage ball 22c and the spherical massage ball 22a having a small diameter are both present. It has a structure that can be attached and detached to a large circular massage ball (22b).

However, the conventional portable low frequency therapy device as described above is not automatically controlled in an analog manner, and the user must determine the treatment time and intensity directly.

Local low frequency treatment time recommended in low frequency treatment is about 15 minutes at the same location, and when used for too long, side effects such as stiffening of the stimulation site occur.

In addition, the conventional portable low frequency therapy device uses the main body as an electrode, so the user uses the hand holding the main body as a loop for current conduction, so the main body must be used to hold the main body with bare hands.

This is not easy to use by the subject with a disability in the arm, even if there is an assistant who helps the treatment of the subject, the therapeutic effect cannot be obtained unless the part of the body of the subject and the assistant is connected.

In addition, the shape of the massage ball was varied in order to show various effects, but this was inconvenient to use because the massage ball had to be replaced to show other effects of the massage during use.

In addition, since it is not easy to carry all the massage balls due to the nature of the portable, it is not easy to use while moving.

The same problem occurs when driving or performing other tasks while performing low frequency treatment.

In addition, the user is configured to convert the electrode applied to the massage ball in contact with the treatment site, but in the case of the + pole to accelerate the blood circulation, in the case of the-pole should be used to calm the blood circulation, the user If this is used in a state where it is not recognized, the muscles of the treatment area are stiffened by using only the + pole continuously, or the use of the-pole continuously does not produce a therapeutic effect.

And, although the intensity of the voltage can be adjusted, this is an analog type, and even when the power is turned off and then turned off, the output is directly output at the set intensity, which indicates a problem such as surprise of the user due to a great intensity treatment from the beginning.

The present invention in view of the above problems is to provide a portable digital low-frequency therapy device that can perform a massage of various effects without replacing the massage ball.

In addition, another object of the present invention is to provide a portable digital low-frequency therapy device that can increase the therapeutic effect without side effects by automatically changing the acceleration and sedation of blood circulation at the most suitable time period without the user directly controlling the pole.

Another object of the present invention is to provide a portable digital low-frequency therapy device that can be easily used by the patient or its assistant by changing the current-carrying loop.

In addition, the present invention aims to provide a portable digital low-frequency therapeutic device that can start treatment from the weakest state in the initial operation and prevent the user from being shocked by a strong current or being shocked by the heart.

In addition, the present invention has a slim structure that is easy to carry, it is possible to convert the tapping speed through the frequency control, portable digital low-frequency therapy device that can reduce the side effects caused by excessive low-frequency treatment by limiting the use time There is another purpose in providing.

The present invention for achieving the above object is an output control key that allows the user to adjust the magnitude of the output current, a frequency adjustment key that allows the user to adjust the frequency of the output current, the power supply according to the operation state of the power key The power supply unit for supply control, the power supply of the power supply unit, the user's input through the output control key and the frequency control key is received, interpreted and outputs the corresponding control signal and the control operation according to the set program And a control unit for displaying the output current and its frequency state on a display unit, and receiving and converting the power supply of the power supply unit under the control of the control unit to output the set output current and the polarity of the output current at a set time period. The central processing unit that converts each other, and the output that is directly supplied to the human body by receiving the output current of the central processing unit As part and, configuring the output current of the central processing unit is supplied to the connected external device according to the user's selection to the external output terminal for supplying an output current to the human body through the external device has its features.

Exposed to the upper surface of the main body 71 to display the intensity of the current treatment device in 0-9 steps, and to display the output frequency 72, the power key 75, and an output control key for adjusting the intensity ( 73a, 73b, frequency adjusting keys 74a, 74b for adjusting the output frequency, two output parts 76a, 76b provided with a surface and a needle, and having different polarities, and the main body 71 of It is composed of an external output terminal 77 which is located at the side and can output by connecting the low frequency current to other equipment.

Each of the output parts 76a and 76b has a bottom surface having an inclined surface, and the surface of the output parts 76a and 76b can be treated at a treatment area having a large area, and have a protruding structure at the front thereof. Depending on the angle of the user can find acupuncture points and can be treated with acupuncture, and the treatment area can be massaged using a wide bottom.

This is a conventional portable low-frequency treatment device has to be replaced by replacing the needle or ball in order to use the needle or ball, the present invention can be treated in the desired manner by adjusting only the angle of contact with the treatment device and the body.

This can enjoy a variety of massage effects without the inconvenience of having to turn off the power of the treatment device during the treatment, to replace with a massage part of a different shape.

9 is a detailed block diagram of a portable digital low frequency treatment device of the present invention, and a power supply unit 100 for supplying power as shown therein; A power key 75 for controlling the operation of the power supply unit 100; Receives power from the power supply unit 100, receives the user's manipulation of the output control keys 73a and 73b and the frequency adjustment keys 74a and 74b, and outputs a set control signal, and displays the output degree and the frequency degree. A controller 80 for displaying on the screen 72 and outputting an operation control signal according to internal program setting; Under the control of the control unit 80, the power of the power supply unit 100 is applied to the central processing to convert under the control of the control unit 80 to output to the output unit (76a, 76b) and the external output terminal 77 Device 90.

Hereinafter, the operation of the present invention configured as described above and its configuration will be described in more detail.

First, the present invention does not use a bulky analog circuit such as a variable resistor using a digital circuit as in the prior art, thereby increasing the integration density of the device and slimming.

That is, the main body 71 is slim and easy to carry in a pocket or the like and can be formed of an insulator such as plastic because it is not used as an electrode.

The user presses the power key 75 for 2 to 3 seconds to turn on the power.

At this time, the power supply unit 100 uses a normal battery or a rechargeable battery, and supplies a stable voltage of 3V.

When power is supplied in this way, the controller 80 performs an initial operation.

That is, the control unit outputs the control signal outputting the output by setting the initial output to the lowest level, ignoring the output of the previous state, and displaying '0' on the display unit 72.

In this initial state, there is no current supplied to the outputs 76a and 76b, and the user makes the outputs 76a and 76b abut on the treatment area and adjusts the output control keys 73a and 73b. When the output is increased, the control unit displays '1' on the display unit 72 and outputs a control signal corresponding thereto.

The central processing unit 90 receiving the control signal supplies the current to the output units 76a and 76b through a line at a set frequency.

In this case, the polarities of the currents supplied to the output units 76a and 76b are different from each other, and a current loop is formed between the two output units 76a and 76b and the human body.

Low-frequency physical therapy can be performed by the formation of such a current loop, and unlike the conventional portable low-frequency therapy, since the main body 71 is not used as an electrode, the main body may be held by bare hands, or a part of the body of the patient may be in contact with an assistant. There is no need for convenient use.

In addition, the currents supplied to the output units 76a and 76b and the external output terminal 77 are set so that their polarities are periodically converted.

That is, while the current of + is output to the output unit 76a and-to the output unit 76b, the pole is changed after a set time of 5 to 10 seconds.

Conventionally, the user directly changes the pole, but this can reduce the occurrence of side effects when the user forgets during use or does not fully understand the function when used without changing the pole.

In this state, the user can adjust the intensity of the output current by adjusting the output control keys 73a and 73b, and the current output state is displayed on the display unit 72 in steps of 0 to 9.

In addition, the user may change the frequency of the current output current by using the frequency adjusting keys 74a and 74b.

At this time, the frequency state of the output current can be confirmed by the user to the extent of blinking of the display unit (72).

The reason for changing the frequency as described above is to obtain various effects of the massage, and changing the frequency can give the user a variety of massage feelings such as knocking and kneading.

The user can directly change the frequency sequentially, or can be set to sequentially change to the programmed frequency.

That is, when the user manipulates the frequency adjustment keys 74a and 74b, the frequency can be set to increase or decrease in specific units according to the increase or decrease, and the massage effect to program a specific frequency by massage in the control unit 80 and other frequencies can be set. The tapping massage effect can be set, and the user can operate the frequency adjusting keys 74a and 74b to select and use the massage or tapping massage, and the kneading and tapping effect can be changed at a set time period.

This automated frequency allows the user to easily obtain the desired massage effect.

The output adjusting keys 73a and 73b control the value of the output current to adjust the intensity of the massage, and the frequency adjusting keys 74a and 74b can adjust the feeling of the massage regardless of the current intensity.

As such, while the treatment is in progress, the controller 80 measures time to automatically cut off the power supplied to the CPU 90 after about 15 minutes have elapsed.

This is because the recommended time for low-frequency treatment is about 15 minutes, and if the treatment is longer than this, muscle side effects may occur.

In addition, when the user turns off the power by operating the power key 75, or the user turns on the power again by operating the power key 75 after the power is cut off after the set time elapses, the output unit 76a, 76b The current output through) is re-initialized so that no current is initially output, and the user gradually increases the output size by manipulating the output control keys 73a and 73b.

This is a function that was not available in the conventional analog method. In the conventional method, the output current is controlled by using a variable resistor. Therefore, the output is turned up to the maximum, the power is cut off, and the power is supplied again without recognizing that the output is set to the maximum. When turned on, suddenly a large current flows into the body and the user may be surprised.

In severe cases, when used by a person with heart disease, a sudden influx of large currents may cause a shock to the heart, resulting in problems such as paralysis of the heart.

In order to prevent this, the present invention is designed to output the initialized output value in the next operation when the power is turned off.

10 is another embodiment of the present invention, and as shown therein, a jack connected to the pad 110 may be inserted into the external output terminal 77 and used.

This allows the pad 110 to be attached to a part of the body while carrying the main body 71 in a pocket, thereby allowing low frequency physiotherapy while driving or performing other tasks.

The positive electrode is also converted to the external output terminal 77 every set time, and the controller 80 serves to cut off power when the set time elapses, so that low frequency physiotherapy is easily performed while performing other tasks without worrying about side effects. You can do it.

In addition, the output portion (76a, 76b) is configured to contact the human body in accordance with its inclination angle as well as the wide surface of the human body, so that the user can easily use a surface for a wide treatment area Can cure, and intensive stimulation of acupuncture points can increase the therapeutic effect.

As described above, the portable digital low frequency therapy device according to the present invention can be manufactured in a slim shape by increasing the degree of integration using a digital circuit, and thus has an effect of being portable.

In addition, by forming a positive / negative electrode on one side to enable low-frequency physiotherapy without using the main body as an electrode, there is an effect that a user or helper can be used more easily and simply.

In addition, the polarity of the positive / negative electrode may be mutually converted at a set time period, and the power may be automatically turned off after the set time, thereby reducing side effects.

In addition, it is possible to change the frequency of the output current as well as the intensity of the output current to provide the user with various massage effects such as a kneading effect and a tapping effect, thereby enabling low frequency physiotherapy with various feelings according to the user's selection.

In addition, the present invention has the effect that when the power is turned off and then turned on again, the output current is initialized to a low value, thereby reducing the side effects caused by a large current that is suddenly introduced.

The present invention has the effect of being able to receive low frequency physiotherapy while performing other tasks by applying an adhesive pad and the like with an external output terminal.
