Description

Eco-friendly low frequency stimulator

The present invention relates to a low-frequency stimulator, and particularly to a low-frequency stimulator using a battery as a power source.

In general, a low-frequency stimulator to a low-frequency treatment device is a type of treatment or external treatment device that treats pain or obesity, such as muscle pain or neuralgia, by stimulating a local part of the human body using a low frequency. It was difficult to use individually at home due to the high price, but recently, as many people have increased interest in health, various health (medical) devices such as small low-frequency treatment devices have been developed and widely used and widely used by the general public. have.

The treatment by electrical stimulation is a method of treating various pains caused by various causes by stimulating the peripheral nerves of the skin using electric current. When the stimulation by low-frequency electricity is given to the extent that the muscle contracts, the pain is relieved. The low-frequency treatment device using the fact that the effect is low-frequency generated from the low-frequency generator using a low voltage is treated by stimulating the local part of the body to which the pad is attached through the pad.

The currently known low frequency stimulator for physical therapy repeatedly outputs a constant voltage set to about 12 to 60 Vp (peak voltage) so that the muscles react through the skin. It is also a kind of low frequency stimulator, but is called a pain therapy device in foreign countries. In the case of a device, the output value of about 500 Vp is output in a very short time (us unit as an instantaneous time), that is, the skin is stimulated by using an instantaneous output (transient voltage) and the pain is treated through the device (low-frequency stimulator, By setting the battery threshold voltage value in consideration of the effective stimulus value that the pain treatment device can maintain its own function (proper stimulation) in advance, it recognizes that the battery is lower than this and the battery replacement sound (beep) It is intended to inform the user to replace the battery with a new warning method.

That is, since the device does not sufficiently exhibit the efficacy of the device below the threshold voltage, the user has to replace the battery by outputting a warning sound or a message to replace the battery even though the battery voltage remains large.

Even though the voltage of the battery remained at a high level, the battery had to be disposed of, causing serious waste of resources, and was not very good in terms of environment.

In addition, the battery replacement cycle was shortened, so there were many inconveniences to users.

That is, since the battery has to be replaced with a threshold voltage even with a little use, there is a problem in that the user's environment is complicated, inconvenient, and the use environment of the low-frequency stimulator is very poor.

On the other hand, in general, the low-frequency stimulator can set the stimulation intensity (output intensity or output level) in several stages, which is set by the user according to the pain area and the degree of pain.

For example, a user with shoulder pain sets and uses the stimulus intensity in 30 steps. As the usage time passes, the voltage of the battery decreases. Therefore, when the voltage of the battery drops to near the threshold voltage, there are many low-frequency output values interlocked. It has to be lowered, and at this time, if the user sets it to 30 steps as it is always used, the stimulus strength is much lower than the strength at the first use, so the stimulus strength has to be raised by much more than the previously used stage.

The present invention was created to solve the problems of the prior art as described above, the purpose of the eco-friendly low-frequency stimulator according to the present invention,

First, even if the voltage value of the battery falls below the initially set threshold voltage value, it is possible to generate an instantaneous pulse output value (effective output value) that can be recognized as a valid stimulus,

Second, in the case of the same effective stimulation, the threshold voltage value of the initially set battery can be lowered and set.

Third, even if the same battery is used, it is possible to increase the usage time for effective stimulation,

Fourth, it is possible to increase the replacement cycle of the battery, and thus, it is possible to take a long period of time to dispose of the battery, so that the overall battery disposal is reduced, so that an eco-friendly low-frequency stimulator can be implemented,

Fifth, the output of the low-frequency stimulator is constant even if the voltage of the battery drops due to the passage of time due to the use of the low-frequency stimulator,

Sixth, it is possible to maintain the output of the low-frequency stimulator at a substantially effective voltage level even if the voltage of the battery drops due to the passage of time due to the use of the low-frequency stimulator,

Seventh, the output of the low-frequency stimulator can produce an output that does not significantly differ from the initial battery full-charge voltage even when the voltage of the battery drops due to the lapse of time due to the use of the low-frequency stimulator.

Eighth, even when the voltage drops due to the use of the battery, the output is similar to the voltage at the first full charge, and at the same time, a stable (constant) output can be produced. It is to provide an eco-friendly low-frequency stimulator that is suitable for use.

Eco-friendly low-frequency stimulator of the present invention for achieving the above object, in a low-frequency stimulator for treatment by giving an electromagnetic stimulation of a low frequency by contacting an electrode to a body part that is a stimulus or treatment, detecting a battery and the voltage of the battery A voltage detector and a current voltage of the battery are received from the voltage detector, and a first output control signal is output until the current voltage of the received battery reaches the first reference voltage, and the current voltage of the received battery is the first. When the reference voltage is reached, the control unit outputs a second output control signal, and receives a first output control signal or a second output control signal from the control unit, and receives the first output control signal or the second output control signal. Therefore, the low-frequency generating unit for generating and outputting different low-frequency, and the user's body, and from the low-frequency generating unit It comprises an electrode for outputting the input low frequency, the low frequency generation unit generates and outputs an uncompensated low frequency, which is an uncompensated normal low frequency, when the first output control signal is received from the control unit, and outputs it. 2 When the output control signal is received, it is recommended to generate and output the compensated low frequency whose instantaneous pulse output value is greater than the uncompensated low frequency. It is characterized by.

Eco-friendly low-frequency stimulator of the present invention having the above configuration has the following effects.

First, even if the voltage value of the battery falls below the initially set threshold voltage value, there is an effect that can generate more effective output (voltage).

Second, in the case of the same effective stimulation, there is an effect that the threshold voltage value of the battery that is initially set can be set lower.

Third, even if the same battery is used, there is an effect of increasing the use time (effective stimulation time) for effective stimulation.

Fourth, by increasing the effective stimulation time in the same battery, the battery can be used for a longer period of time, thereby increasing the replacement cycle of the battery, and as a result, it is possible to take a long period of time to dispose of the battery. It has a reducing effect, and thus, it is possible to implement an eco-friendly low-frequency stimulator, and in this regard, the low-frequency stimulator of the present invention becomes an eco-friendly low-frequency stimulator.

Fifth, there is an effect that the output of the low-frequency stimulator is constant and stable even if the voltage of the battery drops due to the passage of time due to the use of the low-frequency stimulator.

Sixth, there is an effect of maintaining the output of the low-frequency stimulator at an effective voltage level even if the voltage of the battery drops due to the passage of time due to the use of the low-frequency stimulator.

Seventh, even if the voltage of the battery drops to a threshold voltage value due to the passage of time due to the use of the low-frequency stimulator, there is an effect that the output of the low-frequency stimulator can produce an output value similar to the initial battery full voltage.

Eighth, even if the voltage drops due to the use of the battery, it can always produce an output that is similar to the voltage at the first full charge and at the same time a constant (stable) output, reducing the hassle of setting the output intensity from the user's point of view. There is an effect that can be conveniently used.

The following will be described in detail with reference to the accompanying drawings, preferred embodiments of the present invention eco-friendly low-frequency stimulator.

The eco-friendly low-frequency stimulator according to the present invention presupposes a low-frequency stimulator using a battery as a power source.

As shown, the eco-friendly low-frequency stimulator according to an embodiment of the present invention, in a low-frequency stimulator for contacting the electrode 150 to the stimulation or treatment subject to give electromagnetic stimulation of low frequency to treat, each circuit element The battery 110 for supplying the operating current, the voltage detection unit 120 for detecting the voltage of the battery 110, and the current voltage Vp of the battery 110 from the voltage detection unit 120 (current voltage value ( Vp), which has the same meaning in this specification.], And the current voltage Vp of the received battery 110 is full of the battery 110 due to a voltage drop according to the use of the battery 110. The first output control signal is output until the first reference voltage V1 (meaning the first reference voltage value Vp, which has the same meaning in this specification) that is smaller than the voltage Vf is reached, The current voltage (Vp) of the received battery is the first reference voltage (V When reaching 1), the control unit 130 outputs a second output control signal, and receives the first output control signal or the second output control signal from the control unit 130, and receives the first output control signal or A low frequency generator 140 that generates and outputs different low frequencies according to the second output control signal, and an electrode 150 that contacts the pain portion of the user's body and outputs the low frequency input from the low frequency generator 140 It characterized in that it is configured to include.

In this case, when the first output control signal is received from the control unit 130, the low frequency generation unit 140 generates and outputs an uncompensated low frequency, which is a normal low frequency that is not compensated, and outputs the second output from the control unit 130. When a control signal is received, it is characterized in that it generates and outputs a compensated low frequency having a larger instantaneous pulse output value (voltage value) than an uncompensated low frequency.

Specifically, as a method of generating a compensated low frequency having a larger instantaneous pulse output value (voltage value), the low frequency generator 140 receives an uncompensated low frequency when receiving the second output control signal from the controller 130. It is to generate and output a compensated low frequency with a larger instantaneous pulse output value (voltage value) because the operation on time is longer.

When the voltage value of the battery 110 reaches the first reference voltage V1, voltage compensation is immediately performed, and there is an advantage of always maintaining a constant output even when the voltage of the battery drops, and the voltage value of the battery Even when the threshold voltage is lowered, a more effective output (voltage) can be generated.

In the eco-friendly low-frequency stimulator according to an embodiment of the present invention, when the current voltage Vp of the battery 110 is greater than the first reference voltage V1, output compensation is not performed, and the current voltage of the battery 110 When (Vp) is less than or equal to the first reference voltage (V1), the first storage unit 160 in which a compensation output value for storing the output of the low frequency generator 140 is stored is further included, and the control unit 130 ) Reads the compensation output value stored in the first storage unit 160 when the current voltage Vp of the battery received from the voltage detection unit 120 reaches the first reference voltage V1. , Generating the second output control signal in response to the read compensation output value.

In the eco-friendly low-frequency stimulator according to an embodiment of the present invention, the first storage unit 160 may be stored as table information as the compensation output value is matched one-to-one with the current voltage Vp of the battery, or as an embodiment. Depending on the condition, the current voltage Vp may be received from the control unit 130, the current voltage Vp may be input to the compensation output value calculation program to calculate the compensation output value, and then the calculated compensation output value may be stored. It belongs to the technical scope of the present invention.

In the eco-friendly low-frequency stimulator according to an embodiment of the present invention, the compensation output value stored in the first storage unit 160 is characterized in that it is set to be inversely proportional to the voltage value of the drop of the battery 110 and is stored. .

The fact that the compensation output value is inversely proportional to the voltage value of the battery means that when the detected current voltage value of the battery is low, the compensation output value increases.

In the eco-friendly low-frequency stimulator according to an embodiment of the present invention, the compensation output value stored in the first storage unit 160 is a second reference voltage smaller than the first reference voltage V1 from the first reference voltage V1. (V2) [means the second reference voltage value (Vp), which has the same meaning in this specification.] Is set and stored only for the battery voltage value between [that is, compensation under the second reference voltage (V2) The output value is not set.], And the compensation output value means a plurality of section voltages (section voltage values) between the first reference voltage V1 and the second reference voltage V2, and has the same meaning in this specification. .], And is characterized by being discretely matched to this section voltage and stored.

For example, when the first reference voltage V1 is 8.0 V and the second reference voltage V2 is 5.0 V, for example, it can be divided into a section voltage of 7.0 and 6.0 between 8.0 and 5.0.

At this time, when the current voltage Vp of the battery reaches 8.0 V, which is the first reference voltage V, the compensation output value is 100 V, and when the current voltage Vp of the battery is 7.0 V, the compensation output value is 200 V. , If the current voltage (Vp) of the battery is 6.0 V, the compensation output value can be matched with 300 V and stored.

In addition, when the second reference voltage V2 is set to 5.0 V, since the voltage of the battery 110 is low and the output value is compensated because the voltage of the battery 110 is lower than 5.0 V, effective stimulation does not occur, so the second reference voltage V2 is less than Does not set the compensation output value.

In the eco-friendly low-frequency stimulator according to an embodiment of the present invention, the first storage unit 160 is a voltage compensation value storage module 161 that matches the voltage value of the battery 110 and stores the voltage compensation value. It is characterized in that it comprises a compensation output value storage module 162 is stored in the compensation output value is matched to the voltage compensation value stored in the voltage compensation value storage module (161).

The voltage compensation value is a parameter value for calculating or setting the compensation output value.

In the above example, when the current voltage (Vp) of the battery reaches 8.0 V, which is the first reference voltage (V), the voltage compensation value is set to “1”, and the current voltage (Vp) of the battery is 7.0 V. In the case, the voltage compensation value is set to “2”, and when the current voltage Vp of the battery is 6.0 V, the voltage compensation value is set or calculated as “3” and stored in the voltage compensation value storage module 161.

At this time, the compensation output value is 100 V when the voltage compensation value is "1", the compensation output value is 200 V when the voltage compensation value is "2", and the compensation output value is 300 V when the voltage compensation value is "3". It is set or calculated as and stored in the compensation output value storage module 162.

In the eco-friendly low-frequency stimulator according to an embodiment of the present invention, the voltage compensation value storage module 161 calculates or stores the voltage compensation value by inversely proportional to the voltage value of the battery 110 falling. It is characterized by.

The fact that the voltage compensation value is inversely proportional to the voltage value of the battery means that the voltage compensation value increases when the detected current voltage value of the battery is low.

In the eco-friendly low-frequency stimulator according to an embodiment of the present invention, the voltage compensation value stored in the voltage compensation value storage module 161 is a second reference voltage (V2) from the first reference voltage (V1) [first reference The voltage compensation value is set and stored only for the battery voltage value between the voltages (V1), that is, the voltage compensation value is not stored below the second reference voltage V2. It is characterized by being discretely matched to the section voltage between the first reference voltage (V1) and the second reference voltage (V2) and stored.

For example, when the current voltage Vp of the battery reaches 8.0 V, which is the first reference voltage V, the voltage compensation value is “1”, and when the current voltage Vp of the battery is 7.0 V, the voltage compensation value is If it is "2" and the current voltage (Vp) of the battery is 6.0 V, the voltage compensation value may be set and stored as "3".

In addition, when the second reference voltage V2 is set to 5.0 V, since the voltage of the battery 110 is low and the output value is compensated because the voltage of the battery 110 is lower than 5.0 V, effective stimulation does not occur, so the second reference voltage V2 is less than Does not set the voltage compensation value.

The following describes the characteristics of the eco-friendly low-frequency stimulator according to another embodiment of the present invention.

The eco-friendly low-frequency stimulator according to another embodiment of the present invention is characterized in that the output value is compensated only when the battery current voltage Vp reaches the threshold voltage Vc.

The threshold voltage Vc (meaning the threshold voltage value Vp, which has the same meaning in this specification) is data representing a battery voltage value of experience experienced by a user as an effective stimulus, which is preset and stored. For example, when the full voltage is 9 V, the threshold voltage is 7.8 V. When this threshold voltage is reached, it is common to replace the battery because a battery replacement signal (beep sound) is output.

The eco-friendly low-frequency stimulator according to another embodiment of the present invention is characterized in that the output compensation mode selection unit 180 which is a user interface capable of selecting an output compensation mode is further included.

The output compensation mode includes a first output compensation mode and a second output compensation mode.

In the first output compensation mode, the first reference voltage V1 and the threshold voltage Vc are different, the first reference voltage V1 is greater than the threshold voltage Vc, and the battery current voltage reaches the first reference voltage. It is an operation mode in which an output compensation operation is immediately performed, and in the second output compensation mode, the output compensation operation is performed only when the first reference voltage is set to the same value as the threshold voltage Vc and thus the battery current voltage reaches the threshold voltage. This is the operation mode that is performed.

The output compensation mode selector 180 includes a first output compensation mode selector 181 that is a user interface for operating a first output compensation mode, and a second output compensation that is a user interface for operating a second output compensation mode. A mode selector 182 is provided, which will be described in detail below.

Eco-friendly low-frequency stimulator according to another embodiment of the present invention, the second storage unit 170, the threshold voltage (Vc) is stored, and the current voltage (Vp) of the battery 110 is the threshold voltage (Vc) [thus 1 reference voltage V1], the second output compensation mode selector 182, which is a user interface for inputting a command to perform an output compensation operation, is further included.

In this case, when the second output compensation mode selection signal is input from the second output compensation mode selection unit 182, the control unit 130 determines that the current voltage (Vp) of the battery is the threshold voltage. When it reaches (Vc), it outputs, and the first output control signal continues to output until it reaches the threshold voltage (Vc).

That is, the controller 130 receives the current voltage Vp of the battery 110 from the voltage detector 120 and until the current voltage Vp of the received battery reaches the threshold voltage Vc. The first output control signal is output, and when the current voltage Vp of the received battery reaches the threshold voltage Vc, the second output control signal is output.

According to this, since the output voltage is compensated after the threshold voltage Vc, there is an effect of substantially lowering the threshold voltage Vc, thereby extending the use time of the battery 110.

In the eco-friendly low-frequency stimulator according to another embodiment of the present invention, the first reference voltage V1 is greater than the threshold voltage Vc, and when the first reference voltage V1 is reached, an output compensation operation is immediately performed. The first output compensation mode selector 181, which is a user interface for inputting a command, is further configured.

The first output compensation mode is a low-frequency output mode in which the output compensation operation is performed immediately when the first reference voltage V1 is reached before the threshold voltage Vc is reached, which is set as the default value. It may be, or it may be provided with a separate selection key, such as the first output compensation mode selection unit 181 as described above, so that the operation can be performed, in any case is within the technical scope of the present invention.

The following describes the operation of the eco-friendly low-frequency stimulator according to an embodiment of the present invention having the above configuration.

The voltage detector 120 detects the current voltage Vp of the battery 110 (S210), and sends the detected voltage value to the controller 130.

The controller 130 compares the current voltage Vp of the battery with the first reference voltage V1 previously stored in the internal memory (not shown) (S212).

If the current voltage (Vp) of the battery is greater than the first reference voltage (V1) (S212), the output compensation operation is not performed and a normal general operation is performed, so that the first output control signal is generated by the low frequency generator 140 Output (S230), and the low frequency generator 140 receiving the first output control signal outputs a normal low frequency (uncompensated low frequency) having an uncompensated output value to the electrode 150 (S232).

Meanwhile, when the current voltage Vp of the battery is greater than the first reference voltage V1 (S212), an output compensation operation is performed, which will be described in detail.

When the current voltage Vp of the received battery is equal to or less than the first reference voltage V1, the controller 130 reads the voltage compensation value matched to the current voltage Vp from the voltage compensation value storage module 161 to compensate for the voltage. It is set as a value (S214), and a compensation output value matching the set voltage compensation value is read from the compensation output value storage module 162 and set as a compensation output value (S216).

Then, when the compensation output value is set as described above, the controller 130 outputs the second output control signal to the low frequency generator 140 so that the low frequency generator 140 can generate the set compensation output value.

As shown in FIG. 4, the second output control signal (operation on time T2) is a signal for further increasing the operation on time of the low frequency generator 140 compared to the first output control signal (operation on time T1). As a result, the operation on time of Δt is increased compared to the first output control signal.

Therefore, T2 = T1 + Δt.

The low frequency generator 140 receiving the second output control signal increases the on operation time by Δt and outputs a compensated voltage pulse having a larger voltage value (S220).

In the first output compensation mode, output value compensation is performed before the threshold voltage. In particular, when the current voltage of the battery is lowered and the output is lowered, for example, the first reference voltage V1 is the full voltage Vf (the full voltage value). Meaning.] When ~ 88% of [When the full voltage (Vf) is set to 9.0 V, 8.0 V], since output compensation is performed from this point, the output value has the advantage that it can be kept constant at all times. .

This is a very important action and effect, which is described in detail.

Typically, in the low-frequency stimulator, the stimulation intensity (output intensity) can be set from 1 to 40 steps, which is set by the user according to the pain area and the degree of pain.

For example, a user with shoulder pain sets and uses the stimulus intensity in 30 steps. As the usage time passes, the current voltage of the battery decreases, and thus the low-frequency output value linked to the current voltage of the battery is forced to decrease. When used in the 30-step setting as always used, the stimulus intensity was lower than the intensity at the first use, so there was an inconvenience in that the stimulus intensity had to be increased to 40 and used again.

However, the low-frequency stimulator according to an embodiment of the present invention compensates the output value as the current voltage of the battery decreases, so that a constant voltage value is always output, and as a result, the stimulus intensity is always constant even when the user does not set the stimulus intensity. Since the irritation intensity can be maintained, users can conveniently use it for their pain management.

In FIG. 5, the waveform diagram of (a) is a pulse waveform diagram of the output voltage when the current voltage Vp of the battery is below the threshold voltage Vc in the prior art, and the waveform diagram of (b) is the present In the eco-friendly low-frequency stimulator according to an embodiment of the present invention, a pulse waveform diagram of a voltage output from the low-frequency generator 140 when the current voltage Vp of the battery is below the threshold voltage Vc.

In FIG. 5, an effective output voltage value (effective stimulus output voltage value) (+ Ve, -Ve) is displayed. Conventionally, the output value of the low-frequency stimulator is effective stimulus output voltage value (effective output) below the threshold voltage Vc of the battery Voltage value) or less, so the user did not feel an effective stimulus.

However, in the exemplary embodiment of the present invention, it can be seen that the output value is output more than the effective output voltage values (+ Ve, -Ve) by output compensation even at the threshold voltage Vc of the battery.

Therefore, since the battery can be continuously used even below a threshold voltage, the life of the battery can be extended.

It is needless to say that extending the life of the battery as described above can always be extended regardless of the type of the output compensation mode.

On the other hand, in the eco-friendly low-frequency stimulator according to an embodiment of the present invention, the voltage detection unit 120, the control unit 130 and the first storage unit 160 is described as an example that is composed of separate components, respectively However, the present invention is not limited thereto, and the voltage detection unit 120, the control unit 130, and the first storage unit 160 may be embodied as selectively integrated IC chips, for example, the voltage detection unit 120. ) And the control unit 130 may be composed of a single IC chip, and also the control unit 130 and the first storage unit 160 may be composed of a single IC chip, or the voltage detection unit 120 and the control unit ( 130) and the first storage unit 160 may be integrated and constituted by a single IC chip. In any case, it belongs to the technical scope of the present invention.

As described above, preferred embodiments according to the present invention have been described, and it is common knowledge in the art that the present invention can be implemented in other specific forms without changing its technical spirit or essential features in addition to the above-described embodiments. It is self-evident to those who have it. Therefore, the above-described embodiment should be understood as illustrative rather than restrictive.
