Electrotherapy device using envelope of EMG signal
The present invention relates to an electrotherapy device, and more particularly to an electrotherapy device for use in treating urinary incontinence using EMG signals.
Urinary incontinence is a disease that many patients suffer from around the world, and in particular, many women suffer from urinary incontinence due to aftereffects or aging. According to one statistics, about 20-30% of women over 50 years of age in Europe suffer from incontinence.
Conventionally, as a method of treating such incontinence, drug therapy and surgical therapy have been known. However, in the case of surgical operation, the type of treatment is invasive, so the patient has a feeling of rejection, and in the case of drug treatment, there is a problem of adverse effects on the drug and less expectation for cure, and the effect is not so effective. . However, recent developments in noninvasive treatment of urinary incontinence have changed the social perception of urinary incontinence. The main methods of non-invasive treatment of urinary incontinence include the biofeedback method of increasing the contractile force of the vaginal sphincter by repeatedly performing vaginal sphincter contraction movements and electrical stimulation of muscles and nerve cells by applying a current pulse to the vaginal muscle area. There is a neuromuscular electrical stimulation. In addition, for effective treatment, it is preferable to perform concurrently, rather than independently of any one of the above-mentioned biological feedback method and electrical stimulation method.
In this case, when the urinary incontinence is processed using the biofeedback method, the patient performs vaginal muscle contraction training according to a predetermined training sequence, and the patient knows how much the vaginal muscle contracted according to the patient's will during vaginal muscle contraction. It is very important. If the patient perceives that the vaginal muscle contraction ability improves as an objective indicator as the training progresses, the patient's willingness to train becomes stronger and the treatment effect becomes higher. This can lead to a more efficient training program.
Meanwhile, the reason why the EMG signal is measured for the treatment of urinary incontinence is that the magnitude of the EMG signal is proportional to the contraction intensity of the vaginal muscle. Therefore, in order to measure the EMG signal, a conductor is contacted to the epidermis of the vaginal muscle and a voltage signal induced by the conductor is detected to measure the EMG signal. The frequency component of the EMG signal generated in the human muscle is 20 to 800. The band contains more high frequency components than other biological signals.
1 shows a waveform of a typical EMG signal. As can be seen in Figure 1, the EMG signal is a non-periodic alternating waveform that changes with time, it can be seen that a lot of high frequency components. However, in order to observe the contractile force of the muscles, it is not necessary to analyze the instantaneous change of the EMG signal as shown in FIG. 1, but to roughly change the amplitude of the EMG signal, that is, the envelope signal as shown in FIG. 2. It is more preferable to do.
As can be seen in Figure 1, since the original EMG signal detected in the muscle cells contains a lot of high frequency components, in order to prevent errors due to A / D conversion and to increase the signal reliability, the sampling frequency is approximately It is necessary to make more than 1600. However, in order to perform sampling at such a high frequency, there is a problem in that the configuration of the treatment device becomes very complicated, and thus the manufacturing cost increases.
Conventional electrotherapy devices include, for example, incontinence therapy devices, constipation / constipation therapy devices, low frequency physiotherapy devices, and the like. By the way, these electrotherapeutic devices, although their operating principle is similar to each other, due to differences in the shape of the electrode used in each device, it was common to be composed of separate devices, respectively.
Accordingly, it is an object of the present invention to provide an incontinence treatment device that can be manufactured at low cost.
Another object of the present invention is to provide a urinary incontinence treatment apparatus which is simple in construction and can be manufactured in a portable manner.
It is yet another object of the present invention to provide an electrotherapy device that can be used for various medical treatments, such as incontinence treatment, constipation / constipation treatment or low frequency treatment.
It is yet another object of the present invention to provide an incontinence treatment device that allows a patient to more easily recognize the contraction state of muscles while performing electrotherapy.

The electrotherapy device of the present invention refers to a device for measuring and treating EMG signals, in particular, for example, an incontinence treatment device used for urinary incontinence treatment, and an incontinence treatment device used for constipation / constipation treatment. . In addition, the electrotherapeutic device of the present invention includes electrodes for measuring EMG signals from the treatment site or for delivering electrical stimulation signals to muscle cells at the treatment site.

1 illustrates an example of an intact EMG signal detected from muscle cells at a treatment site through an electrode, and FIG. 2 illustrates an envelope of the EMG signal illustrated in FIG. 1.
As described above, in urinary incontinence treatment, the analysis of the instantaneous change of the EMG signal as shown in FIG. 1 is not required, but the size information of the EMG signal as shown in FIG.
The envelope of the EMG signal as shown in FIG. 2 has much lower frequency components than the original EMG signal, and almost all energy is concentrated in a band of less than about 10 Hz. In addition, as mentioned above, in order to sample the EMG signal in the original state, the sampling frequency should be about 1,600 Hz or more, but in order to sample the envelope signal as shown in FIG. 2, it is possible to lower the sampling frequency to 20 Hz. . Therefore, it can be seen that it is very useful to use the envelope of the EMG signal as shown in FIG. 2 when performing signal processing by converting the EMG signal to digital.

Referring to FIG. 4, unlike FIG. 3, the screen 34 displays not only the envelope ENV-EMG of the EMG signal but also the treatment target waveform GOAL-EMG together. By displaying the envelope of the EMG signal (ENV-EMG) and the treatment target waveform (GOAL-EMG) together, the patient receiving the treatment can objectively recognize the progress of the training. Thus, it is possible to induce the patient to contract the muscle in a desired state, which has the advantage of increasing the therapeutic effect.
5 is a view showing the configuration of the urinary incontinence treatment apparatus according to an embodiment of the present invention.
Referring to FIG. 5, the urinary incontinence treatment device includes a body cavity insertion electrode 10, an envelope detector 20, and a display unit 30. The body cavity insertion electrode 10 is inserted into the vagina during treatment and comes into contact with muscle cells to detect EMG signals from the muscle cells. The sensed EMG signal R-EMG is applied to the envelope detector 20. Thus, the EMG signal in its original state as shown in FIG. 1 is converted into an EMG envelope signal as shown in FIG. 2 and output. The EMG envelope signal is applied to the display unit 30 and displayed as shown in FIG. 3.
6 is a block diagram showing the configuration of the urinary incontinence treatment apparatus according to another embodiment of the present invention, the urinary incontinence treatment device is a body cavity insertion electrode 10, the envelope detector 20, the signal processor 40, the memory 50 And a display unit 30. In FIG. 6, the same parts as in FIG. 5 are denoted by the same reference numerals, and description thereof will be omitted.
Referring to FIG. 6, the EMG envelope signal output from the envelope detector 20 is applied to the signal processor 40. The signal processor 40 is coupled to the memory 50. The memory 50 stores information about the treatment target waveform GOAL-EMG. The information on the treatment target waveform (GOAL-EMG) is, for example, data regarding the time and intensity at which the patient must contract the vaginal muscle during treatment. The signal processor 40 analyzes the EMG envelope signal applied from the envelope detector 20, extracts data on the treatment target waveform GOAL-EMG from the memory 50, and transmits the EMG envelope signal to the display unit 30. Output data about the treatment target waveform (GOAL-EMG). In addition, the signal processor 40 may store the analysis result of the EMG envelope signal in the memory 50 as needed. Thus, it can be used later to analyze the patient's treatment history.
7 is a block diagram showing the configuration of the urinary incontinence treatment apparatus according to another embodiment of the present invention, the body cavity insertion electrode 10, the EMG signal processor 80, the stimulus signal generator 70, the main controller 90 ), A memory 50, a display unit 30, and an operation unit 60. In FIG. 7, parts identical to those of FIGS. 5 and 6 are denoted by the same reference numerals, and description thereof will be omitted.
Referring to FIG. 7, the EMG signal processor 80 includes an envelope detector 20, and the EMG signal R-EMG, which is applied from the body cavity insertion electrode 10, receives an EMG envelope signal. The EMG envelope signal (D-EMG) of the digital form is applied to the main controller 90 by converting and converting it to digital as necessary. The main controller 90 analyzes the EMG envelope signal D-EMG from the EMG signal processing unit 80, and displays the analysis result data and data on the treatment target waveform GOAL-EMG from the memory 50. The data is converted into data suitable for operation at 30 and output to the display unit 30. Such a controller can typically be implemented using a microprocessor. The user may select an operation mode of the urinary incontinence treatment device through the operation unit 60. Specifically, when the EMG signal is to be measured from the vaginal muscle cells using the body cavity insertion electrode 10, the measurement mode is selected, and the electrical stimulation signal S to the vaginal muscle cells through the body cavity insertion electrode 10 is obtained. If you want to apply -SIG) you can select the stimulation mode. In addition, when a certain stimulus signal (S-SIG) is applied to the vaginal muscle cells, the mixed mode may be selected in order to measure the EMG signal according to the vaginal muscle contraction. That is, in the mixed mode, the stimulus operation and the measurement operation are alternately performed. The user can select using the operation unit 60 whether to switch from the stimulus operation to the measurement operation manually or automatically in the mixed mode. In addition, when the automatic operation switching is selected, it is also possible to set the operation switching cycle through the operation unit 60.
According to an exemplary embodiment, when the patient presses a specific button of the manipulation unit 60, the stimulus signal S-SIG of the selected type may be applied to the vaginal muscle cells through the body cavity insertion electrode 10. In this case, the specific button of the operation unit 60 may be configured in a form that can be easily held by the patient or doctor hand.
In mixed mode, the patient performs urinary incontinence treatment by electrical stimulation (i.e., stimulation mode) and biofeedback (i.e., measurement mode), at which time the treatment target waveform (GOAL-EMG) and EMG envelope appear on the display unit 30. You need to contract your vaginal muscles so that the signals match as much as possible.
The user may also adjust the shape of the stimulus signal applied to the muscle cells through the body cavity insertion electrode 10 using the manipulation unit 60. For example, the type of the waveform of the stimulus signal S-SIG, the intensity of the signal, the frequency, and the like may be adjusted. Waveforms that can be used as the stimulus signal S-SIG include pulse waves, sine waves, and the like, and various types of pulses may be used even in the case of pulse waves. In addition, even when the stimulus signal S-SIG is a sine wave, various types of sine waves may be used, such as a full wave and a half wave. The stimulus signal may be a current pulse or a voltage pulse.
The user's control signals are applied to the main controller 90 through the operation unit 60. Among the control signals input through the manipulation unit 60, data regarding waveforms in the stimulus signal S-SIG may be stored in the memory 50 as necessary. Thus, the inconvenience of having the user input data relating to the stimulus signal S-SIG every time can be eliminated.
The stimulus signal generator 70 generates an electrical stimulus signal S-SIG to be delivered to muscle cells through the body cavity insertion electrode 10 under the control of the main controller 90. Here, the main controller 90 generates the stimulus signal by generating data on the stimulus signal S-SIG input to the operation unit 60 and / or data on the stimulus signal S-SIG stored in the memory 50. After converting into a form suitable for the unit 70, and outputs to the stimulus signal generator 70, and activates the stimulus signal generator 70 in accordance with the selected operation mode.
FIG. 8 is a block diagram illustrating a specific embodiment of the display unit 30 and the EMG signal processor 80 illustrated in FIG. 7.
Referring to FIG. 8, the EMG signal processor 80 includes an analog / digital converter (hereinafter referred to as an 'A / D converter') 86, an envelope detector 20, a noise filter 84, and an amplifier 82. The display unit 30 includes a display control unit 32 and a screen 34.
The EMG signal R-EMG sensed through the electrode 10 is applied to the amplifier 82 and amplified. In general, the EMG signal R-EMG sensed through the electrode 10 needs to be amplified by the amplifier 82 because the signal strength is very weak. The amplifier 82 may be implemented as a differential amplifier, and although not shown in the drawing, a reference potential generator coupled to the amplifier 82 may be further included. In this case, two inputs of the differential amplifier and the output of the reference potential generator may be coupled to a plurality of conductive bands included in the electrodes, respectively.
The output of amplifier 82 is applied to noise filter 84 to remove noise. The noise filter 84 can be configured substantially as a band pass filter. In this case, the pass band of the noise filter 84 is preferably set to 20 to 800 kHz. The output F-EMG of the noise filter 84 is applied to the envelope detector 20. According to an embodiment, the envelope detector 20 may be configured as a low pass filter. In addition, the amplifier 82 and the noise filter 84 may be generally implemented using at least one operational amplifier (OP AMP), respectively.
The EMG signal as shown in FIG. 1 is converted into an EMG envelope signal as shown in FIG. 2 through the envelope detector 20. The output E-EMG of the envelope detector 20 is applied to the A / D converter 86 to be converted into a digital EMG envelope signal D-EMG and then applied to the main controller 90.
On the other hand, the display control unit 32 of the display unit 30 receives data to be displayed from the main controller 90. Examples of the display data include data on an EMG envelope signal, data on a treatment target waveform (GOAL-EMG), and the like. The display control unit 32 having received such display data performs control for displaying such display data on the screen 34. Thus, on the screen 34, only the EMG envelope signal ENV-EMG is displayed with respect to the reference voltage line REF as shown in FIG. 3, or as shown in FIG. 4, on the reference voltage line REF as shown in FIG. The EMG envelope signal (ENV-EMG) and the treatment target waveform (GOAL-EMG) are superimposed. In addition, if necessary, data indicating the current operation mode can be applied from the main controller 90 to the display control unit 32 to display the operation mode at a predetermined position on the screen 34. Here, the screen 34 does not display an EMG signal containing a large number of high frequency components as shown in FIG. 1, but displays an EMG envelope signal as shown in FIG. 2, so that the screen 34 can be implemented at a low resolution. . For example, the display unit 30 including the screen 34 may be implemented as a low-cost, low-power consumption, low-resolution liquid crystal display panel. The display unit may also be implemented as an LED device.
In addition, as shown in FIG. 4, when the display unit 30 displays not only the EMG envelope signal but also the treatment target waveform (GOAL-EMG), the patient has an EMG envelope signal as long as possible with the treatment target waveform (GOAL-EMG). Will contract their vaginal muscles to match.
FIG. 9 is a block diagram illustrating another embodiment of the EMG signal processor 80 shown in FIG. 7. The EMG signal processor 80 is divided into a combined EMG signal processor 80a and a separate EMG signal processor 80b. .
The integrated EMG signal processing unit 80a may be integrally assembled with the main controller 90, the memory 50, the display unit 30, the operation unit 60, and the stimulus signal generator 70 in FIG. 7. Hereinafter referred to as the 'device body'), an amplifier 82a, a noise filter 84a, an envelope detector 20a, an A / D converter 86, a receiver 88 and a channel selector 87 do. The EMG signal R-EMG detected by the electrode 10 in the integrated EMG signal processor 80a is amplified by the amplifier 82a and noise is removed from the noise filter 84a. The output F-EMG1 of the noise filter 84a is extracted by the envelope detector 20a and applied to the channel selector 87 by extracting the EMG envelope signal E-EMG1.
The separate EMG signal processor 80b is configured to be physically separated from the main body of the device, and includes an amplifier 82b, a noise filter 84b, an envelope detector 20b, and a transmitter 89. In the isolated EMG signal processing section 80b, the amplifier 82b, the noise filter 84b, and the envelope detector 20b are the amplifiers 82a, the noise filter 84a, and the envelope detector 20a of the integrated EMG signal processing section 80a. ) And the same operation. The output of the envelope detector 20b of the separated EMG signal processor 80b is wirelessly transmitted through the transmitter 89. The EMG envelope signal transmitted through the wireless transmission path 91 is received through the receiver 88 and then applied to the channel selector 87. The channel selector 87 receives either an EMG envelope signal E-EMG1 from the envelope detector 20a or an EMG envelope signal E-EMG2 derived from the envelope detector 20b according to the channel selection signal CS.
