Abstract
Description
[0001] The invention relates to the technical field of electronic devices, in particular a neurostimulator for ejaculation control.
[0002] Premature ejaculation is one of the most common sexual dysfunctions in men. Causes include psychological factors, hormonal imbalances, hypersensitivity of the glans penis, and other associated conditions such as chronic prostatitis (CPPS) and neurological disorders. Some patients suffer from an excess of nerves in the base of the penis, resulting in excessively intense sexual stimulation signals and a rapid attainment of arousal threshold, which, like preterm labor, leads to premature ejaculation. In these patients, surgical resection of some of the nerves in the base of the penis can be performed. However, the effectiveness of this procedure varies: removing too few nerves may not improve sensation, while removing too many nerves may lead to loss of function.
[0003] Current neuromodulation approaches mainly focus on extremely low frequency electrical stimulation (ELS) (<1 kHz) and ultra high frequency (UHF) electrical stimulation (>200 kHz). The mechanism of action of low frequency ELS is not fully understood, but it is generally believed to primarily disrupt or excite nerves. The disruptive effect is very short-lived; once the electrical stimulation ends, the disruption disappears immediately, and nerve sensitivity returns rapidly. Because of the short-term disruptive effect, some ELS approaches even require the device to remain in operation during sexual intercourse, which may impair sexual performance and fail to meet the actual needs of patients. Furthermore, extremely low frequency electrical stimulation treatments require 30 minutes per session, approximately 2-3 times per week.Some effects may not become apparent until 2-3 months of continuous treatment. Furthermore, relapses after discontinuation of treatment are common, significantly reducing patient adherence. Furthermore, improper electrical stimulation can irritate neural networks, further increasing nerve sensitivity. Ultra-high frequency electrical stimulation carries the risk of heat generation, sintering, or excessive blockage of nerve conduction, thereby impairing other normal sexual functions such as erections and rigidity.
[0004] On the other hand, most conventional neuromodulation devices are large devices or integrated devices. Large devices are often installed in hospitals, so patients often need to go to the hospital for treatment. Integrated devices can be used at home, but due to their size and weight, they are difficult to wear on the penis, a special part of the body, for a long time. In particular, it is difficult to maintain a penile erection for a long time under normal circumstances, so long-term continuous stimulation of the penis is not possible with integrated devices. In addition, the nerves in this special part of the penis are relatively dispersed. If a conventional common single-point electrode is directly attached to the penis, the number of nerves covered is very limited, which also directly affects the treatment effect.
[0005] The invention is based on the object of creating a neurostimulator for ejaculation control which is a safe and effective device that is easy to wear and use.
[0006] The object is achieved according to the invention by a neurostimulator for ejaculation control having the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
[0007] The neurostimulator for ejaculation control according to the invention comprises: a basic unit comprising: an electrical stimulation circuit comprising a multi-frequency stimulation circuit and a mixed-frequency stimulation circuit, wherein the multi-frequency stimulation circuit can deliver electrical currents for electrical stimulation at multiple frequencies, and the mixed-frequency stimulation circuit controls the electrical stimulation circuit such that the electrical stimulation circuit delivers electrical currents for stimulation at mixed frequencies; and an output electrode disposed exposed on the outer surface of the base unit and electrically connected to the electrical stimulation circuit, the output electrode receiving the electrical currents output by the electrical stimulation circuit for stimulation at mixed frequencies; and a stimulation element comprising a touch electrode and a stimulation electrode, wherein the touch electrode and the stimulation electrode are electrically connected to each other.
[0008] When the neurostimulator is in use, the output electrode of the base unit is brought into contact with the touch electrode of the stimulation element in order to transmit the electrical currents for electrical stimulation and / or electrical currents for stimulation with mixed frequencies generated by the electrical stimulation circuit to the stimulation electrode.
[0009] The neurostimulator for ejaculation control according to the invention has the following advantages.
[0010] The neurostimulator for ejaculation control according to the invention is designed to be compact and consists of several parts, which makes it easier to carry and at the same time avoids the problem with single-piece neurostimulators that the neurostimulator exerts great pressure on the penis over a longer period of time during treatment.
[0011] According to the invention, the base unit and the stimulation element transmit the electrical stimulation through contact, eliminating the need for an electrical cable. This makes storing and transporting the neurostimulator easier. It also prevents the electrical cable and the power cord from becoming tangled during use.
[0012] According to the invention, the stimulation element is made of elastic material and can be adjusted to the patient's penis size. The stimulation electrode is curved so that it can cover all the nerves in the penis, ensuring a complete and precise treatment. Furthermore, the distance between the contacts of the stimulation electrode is designed to achieve an effective electronic field, allowing the stimulation electrode to effectively affect the nerves.
[0013] The neurostimulator according to the invention delivers multiple electrical stimulation currents in the frequency range of 10-200 kHz as electrical stimulation currents with mixed frequencies, either sequentially or selectively, to prevent premature ejaculation. By enhancing the brain's central nervous system's ability to control ejaculation and reducing excitation of the nerves at the base of the penis, the effectiveness of neuromodulation approaches against premature ejaculation is improved, while also reducing the risk of adverse reactions such as erectile dysfunction and loss of penile rigidity in patients, thus increasing the safety of using the neurostimulator.
[0014] In the neurostimulator according to the invention, electrical stimulation currents with mixed frequencies are used for electrical stimulation, whereby the treatment time is advantageously shortened to 30~60s per session and the effect is immediately noticeable after the treatment.
[0015] The invention is described in detail below using exemplary embodiments and with reference to the drawing.

[0016] The objects, features, and advantages of the present invention are explained in more detail below with reference to the detailed description of exemplary embodiments and the accompanying drawings. The invention is not intended to be limited to the features apparent from the description and the drawings.
[0017] As in Fig.1 and Fig. As shown in Figure 2, the neurostimulator for ejaculation control according to the invention comprises a base unit 1 and a stimulation element 2. The base unit 1 comprises an output electrode 10 arranged exposed on the surface of a base unit housing 11 of the base unit 1. According to the invention, electrical stimulation currents with mixed frequencies generated by the base unit 1 are transmitted to the stimulation element 2 through the contact of the output electrode 10 with the stimulation element 2.
[0018] Out of Fig. 1 to Fig.3 shows that an electrical stimulation circuit 12 and a power source 13 electrically connected to the electrical stimulation circuit 12 are arranged in the base unit housing 11 of the base unit 1, with the power source 13 supplying power to the electrical stimulation circuit 12. A switch 14 is arranged on the outer surface of the base unit housing 11.
[0019] The electrical stimulation circuit 12 includes a multi-frequency stimulation circuit (not shown) and a mixed-frequency stimulation circuit (not shown). The multi-frequency stimulation circuit can deliver electrical currents for electrical stimulation at multiple frequencies. The mixed-frequency stimulation circuit controls the electrical stimulation circuit so that the electrical stimulation circuit mixes the different frequencies of the electrical currents for electrical stimulation and then delivers electrical currents for stimulation at mixed frequencies.
[0020] Preferably, the multi-frequency stimulation circuit can output at least low-frequency electrical stimulation currents and high-frequency electrical stimulation currents, wherein the frequencies of the low-frequency electrical stimulation currents are greater than or equal to 10 kHz and less than 100 kHz, and the frequencies of the high-frequency electrical stimulation currents are greater than or equal to 100 kHz and less than 200 kHz. Low-frequency stimulation currents are less able to penetrate cell membranes, but have a better ability to induce nerve action potentials, strengthen the connection between nerves and neural networks of the brain, and provide feedback during treatment, thus enhancing the ability of the brain's central nervous system to control ejaculation. High-frequency stimulation currents can penetrate cell membranes well, and the impedance decreases rapidly with increasing frequencies.The capacitive component increases, and a large portion of the electrical currents begins to flow into the nerve cells (Ri). This affects the activity of the nerve cells within the cells and disrupts communication between the nerve cells, thereby increasing the ejaculation threshold. Furthermore, the low- and high-frequency electrical stimulation currents act on the nerves at the base of the penis, ensuring greater safety. At the same time, the nerves are trained to act as dampeners so that nerve conduction is not damaged or blocked. This can prevent patients from losing normal sexual functions such as erection and rigidity.
[0021] When the frequency of the electrical stimulation current is lower than 10 kHz, the electrical current essentially flows through the extracellular fluid and can only induce action potentials on the cell membranes. It can only produce brief sensory stimulation or muscle twitching in patients, and it is difficult to achieve the effect of inhibiting nerve excitation. When the frequency of the stimulation current is higher than 200 kHz, the capacitive effect is weakened, and the impedance is mainly determined by the intracellular fluid. The impedance changes little, which can easily lead to heat generation and sintering or blockage of nerve conduction, resulting in more serious damage to the patient.
[0022] As in Fig.As shown in Figure 2, the stimulation element 2 comprises a touch electrode 21 and a stimulation electrode 22. A receiving space 23 is provided inside the stimulation element 2 for receiving parts of the penis to be stimulated, so that the parts of the penis to be stimulated are absorbed by the stimulation element 2. When the stimulation element 2 is applied to the penis, the touch electrode 21 is located on an outer surface 24 of the stimulation element 2, and the stimulation electrode 22 is located on an inner surface 25 thereof, with the touch electrode 21 and the stimulation electrode 22 being electrically connected to one another. An opening 26 is provided at at least one end of the receiving space 23.
[0023] As in Fig.As shown in Figure 4, when using the neurostimulator, the output electrode 10 must be brought into contact with the touch electrode 21 of the stimulation element 2 in order to transmit the electrical stimulation currents with mixed frequencies output by the base unit 1 via the output electrode 10 and the touch electrode 21 to the stimulation electrode 22.
[0024] Furthermore, the invention relates to two control methods for the circuit for electrical stimulation of the neurostimulator according to the invention for ejaculation control, namely a control method for frequency mixing after consideration and a control method for frequency mixing over time. The two control methods are explained in detail below.
[0025] As in Fig. As shown in Figure 5, the control method for frequency mixing according to the invention comprises the following steps: Step 1 "Outputting Multiple Electrical Stimulation Currents": The power source 13 is turned on to energize the electrical stimulation circuit 12. The multi-frequency stimulation circuit in the electrical stimulation circuit 12 outputs multiple electrical stimulation currents to the mixed-frequency stimulation circuit. The frequencies of the electrical stimulation currents are different and range from 10 to 200 kHz, and the frequency of at least one of the electrical stimulation currents is in the range from 100 to 200 kHz. Step 2 “Outputting the electrical stimulation currents in a mixed frequency mode”: The mixed frequency stimulation circuit receives the said electrical stimulation currents and outputs electrical stimulation currents with mixed frequencies in a frequency mixing mode to the output electrode 10.
[0026] In the frequency mixing mode, the mixed-frequency stimulation circuit simultaneously receives multiple electrical stimulation currents and mixes the electrical charge energy generated by these electrical stimulation currents, thereby generating electrical stimulation currents with mixed frequencies. The electrical charge energy generated by the electrical stimulation currents with frequencies of 100-200 kHz accounts for 30-100% of the electrical charge energy of said electrical stimulation currents with mixed frequencies. Preferably, the electrical charge energy generated by the electrical stimulation currents with frequencies of 100-200 kHz accounts for 50-100% of the electrical charge energy of said electrical stimulation currents with mixed frequencies.
[0027] As in Fig.6, the frequency mixing control method according to the invention comprises the following steps in time sequence: Step 1 "Outputting electrical stimulation currents at a single frequency": The power source 13 is turned on so that the electrical stimulation circuit 12 becomes current-conducting. The mixed-frequency stimulation circuit in the electrical stimulation circuit 12 controls the multi-frequency stimulation circuit so that the multi-frequency stimulation circuit outputs electrical currents at a single frequency to the output electrode 10. Step 2 "Outputting electrical stimulation currents at mixed frequencies": The step of outputting electrical stimulation currents at a single frequency is repeated several times, with two consecutive operations of outputting electrical stimulation currents at a single frequency being performed at a time interval of t, where t≥0.The frequency of the electrical stimulation currents output in one process is different from the frequency of the electrical stimulation currents output in the last process, wherein the frequencies of said electrical stimulation currents are in the range of 10~200 kHz, wherein the frequency of at least one of the electrical stimulation currents is in the range of 100~200 kHz.
[0028] Preferably, the duration of the electrical stimulation currents with frequencies of 100-200 kHz accounts for 30-100% of the output duration of said electrical stimulation currents with mixed frequencies. Preferably, the duration of the electrical stimulation currents with frequencies of 100-200 kHz accounts for 50-100% of the output duration of said electrical stimulation currents with mixed frequencies.
[0029] As in Fig.As shown in Figure 4, to use the neurostimulator according to the invention for ejaculation control, the stimulation element 2 is applied to a penis 2 such that the contact electrode 22 comes into contact with the root nerves of the penis 3. Next, the output electrode 10 on the base unit 1 is brought into contact with the contact electrode 21 on the stimulation element 2. The power source 13 is then switched on to energize the electrical stimulation circuit 12. The base unit 1 will then control the neurostimulator using either the frequency mixing after balancing control method or the frequency mixing in time control method so that the neurostimulator electrically stimulates the nerves of the root of the penis.
[0030] In the following, the technical measures of the present invention are explained in more detail using exemplary embodiments. First embodiment
[0031] In the first embodiment, a charging socket 15 is arranged on the surface of the base unit housing 11, which can be electrically connected to the power source 13. The charging socket 15 is connected to an external power source via a power cable to charge the power source 13.
[0032] As in Fig. 2, Fig. 7 and Fig.8, the stimulation element 2 in the first embodiment is a bandage woven from elastic material and formed into an annular sleeve by connecting the starting end to the final end, although the design is not limited thereto. It is conceivable to manufacture the stimulation element 2 from elastic rubber and to form it in a cup and ring shape. The receiving space 23 has an opening 26 at each end. A touch electrode 21 is arranged on the outer surface 24 of the stimulation element 2 and comprises at least two large-area metal contacts 211. A stimulation electrode 22 is arranged on the inner surface 25 of the stimulation element 2 and comprises at least two strip-shaped, large-area electrode contacts 221.The length of each large-area electrode contact 221 is at least half the circumferential length of the inner wall of the annular sleeve, allowing the stimulation element 2 to cover all nerves on the penis when applied to the penis 2. In this way, a complete and precise treatment is achieved.
[0033] The distance between the two electrode contacts 221 is greater than or equal to 1 mm and less than 30 mm. This creates an effective electronic field, allowing the stimulation electrode 11 to effectively affect the nerves to treat the penis with electrical stimulation.
[0034] In the first example, patients were treated using the frequency mixing control method. The duration of the high-frequency electrical stimulation currents with frequencies of 100–200 kHz accounts for 50% of the output duration of the mixed-frequency electrical stimulation currents. The duration of the low-frequency electrical stimulation currents with frequencies of 10–100 kHz accounts for 50% of the output duration of the mixed-frequency electrical stimulation currents. The parameters for the frequency mixing are detailed as follows: The mixed-frequency simulation circuit controlled the multi-frequency simulation circuit so that the multi-frequency simulation circuit continuously outputted low-frequency electrical stimulation currents at frequencies of 10 to 20 kHz for 50 to 60 ms. After 450 to 500 ms, the mixed-frequency simulation circuit controlled the multi-frequency simulation circuit so that the multi-frequency simulation circuit continuously outputted high-frequency electrical stimulation currents at frequencies of 190 to 200 kHz for 50 to 60 ms. After 450 to 500 ms, the mixed-frequency simulation circuit controlled the multi-frequency simulation circuit so that the multi-frequency simulation circuit continuously outputted electrical stimulation currents at frequencies of 10 to 20 kHz for 50 to 60 ms. The process was repeated in this way. Test verification
[0035] Patients with refractory premature ejaculation who had failed to respond to treatment with electrical stimulation currents at frequencies below 1 kHz were recruited for the study. These participants met the diagnostic criteria for premature ejaculation defined by the International Association of Sexual Medicine. Patients had to be in a stable heterosexual relationship with a single partner for at least six months, have sexual intercourse at least twice a week throughout the study period, and have not used any other treatments for premature ejaculation for at least three months. Their intravaginal ejaculatory latency time (IELT) was 15–60 seconds.
[0036] Twenty patients were treated with the ejaculation control neurostimulator in the first embodiment three times a day for one month, with each treatment lasting one minute. The collected data on the average intravaginal ejaculation latency before the start of treatment and after one month of treatment are shown in Table 1 below. Table 1 - IELT before and after treatment in comparison IELT before treatment (unit: second) IELT after one month of treatment (unit: second) Patient 1 15 80 Patient 2 30 120 Patient 3 30 150 Patient 4 20 120 Patient 5 60 120 Patient 6 60 180 Patient 7 20 120 Patient 8 30 600 Patient 9 60 300 Patient 10 20 45 Patient 11 10 50 Patient 12 10 10 Patient 13 10 15 Patient 14 30 180 Patient 15 60 140 Patient 16 60 150 Patient 17 10 50 Patient 18 30 80 Patient 19 60 300 Patient 20 60 480 Test result
[0037] During the test, none of the twenty patients reported any adverse reactions, indicating the neurostimulator's high level of safety. Furthermore, all twenty patients were able to operate the neurostimulator and administer the treatment themselves at home. None of the twenty patients discontinued the test early, demonstrating user-friendliness of the neurostimulator and adherence to therapy.
[0038] As shown in Table 1, the IELT scores of all patients, except for patients 12 and 13, were double or more than double their pre-treatment values. Eleven patients (more than 50% of the total study participants) had IELT scores that were five times or more than five times their pre-treatment values. It can be seen that their premature ejaculation improved progressively and significantly with the extension of the treatment period. Second embodiment
[0039] In the second embodiment, the patients were treated using the frequency mixing control method over time. The same current frequencies were selected as in the first embodiment. The percentages of the respective time durations for the output of the low- and high-frequency electrical stimulation currents relative to the electrical stimulation currents with mixed frequencies are also the same as in the first embodiment.The parameters for the frequency mixing over time were as follows: low-frequency electrical stimulation currents were delivered continuously for 10–20 ms; then the neurostimulator was switched to deliver high-frequency electrical stimulation currents continuously for 10–20 ms; this process was repeated for 100 ms, and then the neurostimulator stopped delivering electrical stimulation currents; and then, after a pause of 800–1000 ms, low-frequency electrical stimulation currents were delivered again. The process was repeated in this way. Test verification
[0040] Patients with refractory premature ejaculation who were not responsive to treatment with electrical stimulation currents with frequencies below 1 kHz were selected as study participants.
[0041] Forty patients were selected who were diagnosed with primary premature ejaculation in the outpatient clinic, and all treatments had been discontinued for more than three months. These patients had a stable frequency of sexual intercourse. The patients were randomly divided into two groups: a test group (n=20) and a control group (n=20). The patients in the test group were treated with the neurostimulator in the second embodiment. The patients in the control group were treated with electrical stimulation currents at frequencies of 200–800 kHz using a sensitivity reduction device. The other parameters of the electrical stimulation currents for the neurostimulator and the sensitivity reduction device were identical. The treatment of the patients in both groups lasted continuously for two weeks. The treatment was performed twice a day for one minute.After two weeks, the average IELT scores before and after treatment of the forty patients were collected. If the intravaginal ejaculation latency doubled or increased by more than twofold, the treatment was considered effective. Safety of use was measured by whether the treatment caused side effects such as erectile dysfunction and loss of penile rigidity.
[0042] Below, data from the test group are shown in Table 2 and data from the comparison group are shown in Table 3. Table 2 - Data of the test group Ejaculation latency time before treatment (second) Ejaculation latency time after treatment (second) Side effects after treatment Patient 1 30 70 No Patient 2 60 140 No Patient 3 120 370 No Patient 4 15 40 No Patient 5 60 240 No Patient 6 40 180 No Patient 7 60 140 No Patient 8 45 100 No Patient 9 30 180 No Patient10 50 120 No Patient11 30 50 No Patient12 120 500 Loss of penis stiffness Patient13 45 100 No Patient14 10 15 No Patient15 15 100 No patient 60 150 No 16 Patient17 120 360 No Patient18 360 540 No Patient19 15 60 No Patient20 60 180 No Table 3 - Data of the comparison group Ejaculation latency time before treatment (second) Ejaculation latency time after treatment (second) Statistics on side effects Patient 1 40 130 No Patient 2 60 150 No Patient 3 30 erectile dysfunction Patient 4 40 60 Loss of penile stiffness Patient 5 10 30 No Patient 6 20 50 No Patient 7 60 180 Loss of penile stiffness Patient 8 40 120 Patient 9 30 100 Patient 10 15 40 Patient 11 20 30 Patient 12 30 110 Loss of penile stiffness Patient 13 40 120 Patient 14 30 erectile dysfunction Patient 15 45 100 Patient 16 30 70 Patient 17 30 erectile dysfunction Patient 18 120 400 Patient 19 100 240 Patient 20 80 260 Test result
[0043] Comparing Table 2 with Table 3, it can be seen that the treatment was effective in eighteen of the twenty patients in the test group, with an efficacy rate of 90%. Only one patient experienced loss of penile rigidity, with an efficacy rate of 5%. Fifteen of the twenty patients in the comparison group experienced the treatment, with an efficacy rate of 75%. Only three patients experienced erectile dysfunction, and four patients experienced loss of penile rigidity, with an efficacy rate of 35%. The difference between the efficacy rates and the difference between the efficacy rates of adverse reactions in these two groups are statistically significant (P<0.05).
[0044] Conclusion: The neurostimulator in the second embodiment proved to be more efficient and safer to use and is more suitable for patients with premature ejaculation. Extended use of the neurostimulator in the second embodiment may potentially improve the quality of sexual intercourse in these patients.
[0045] The success of the treatment lies in the fact that the use of high-frequency electrical stimulation currents with frequencies of 10–200 kHz can reduce the excitation of the nerves at the base of the penis without completely blocking nerve conduction. This reduces the sensitivity of part of the penis, while the patient's penis remains sensitive and can respond to stimulation, thus maintaining erection and penile rigidity, and maintaining sexual pleasure. The use of electrical stimulation currents with frequencies above 200 kHz can lead to a more severe nerve blockage or heat generation in the stimulation element.When such an application is performed, the sensitivity of a part of the penis is reduced and the nerve conduction of other normal sex-related information is also slightly prevented, so that normal penile functions such as erection and penile rigidity are impaired, leading to a higher rate of development of adverse reactions. Third embodiment
[0046] In the third embodiment, the balancing frequency mixing control method is employed, in which the multi-frequency stimulation circuit simultaneously outputs two electrical stimulation currents with different frequencies to the mixed-frequency stimulation circuit, which two electrical stimulation currents include a low-frequency electrical stimulation current with frequencies of 10~100 kHz and a high-frequency electrical stimulation current with frequencies of 100~200 kHz.
[0047] The mixed-frequency stimulation circuit receives the electrical charge energy generated by the low-frequency electrical stimulation current and the electrical charge energy generated by the high-frequency electrical stimulation current and mixes these energies, creating electrical stimulation currents with mixed frequencies that are output to the output electrode. The electrical charge energy generated by the low-frequency electrical stimulation current accounts for 50% of the electrical charge energy generated by the mixed-frequency electrical stimulation currents. The electrical charge energy generated by the high-frequency electrical stimulation current accounts for 50% of the electrical charge energy generated by the electrical stimulation currents.
[0048] In the third embodiment, the frequencies of the low-frequency electrical stimulation currents are 10–20 kHz, and the frequencies of the high-frequency electrical stimulation currents are 100–200 kHz. Other design details are the same as those of the first embodiment.
[0049] In combination of the first embodiment with the second embodiment, the following advantages can be observed in the neurostimulator for ejaculation control according to the invention.
[0050] The neurostimulator according to the invention is designed to be compact and made up of several parts, which makes it easier to carry and at the same time avoids the problem with single-piece neurostimulators that the neurostimulator exerts great pressure on the penis over a longer period of time during treatment.
[0051] According to the invention, the base unit and the stimulation element transmit the electrical stimulation through contact, eliminating the need for an electrical cable. This makes storing and transporting the neurostimulator easier. It also prevents the electrical cable and the power cord from becoming tangled during use.
[0052] According to the invention, the stimulation element is made of elastic material and can be adjusted to the patient's penis size. The stimulation electrode is curved so that it can cover all the nerves in the penis, thus achieving a complete and precise treatment. Furthermore, the distance between the contacts of the stimulation electrode is designed to achieve an effective electronic field, allowing the stimulation electrode to effectively affect the nerves.
[0053] The neurostimulator according to the invention delivers multiple electrical stimulation currents in the frequency range of 10-200 kHz as electrical stimulation currents with mixed frequencies, either sequentially or after balancing, using a frequency mixing control method to prevent premature ejaculation. By enhancing the brain's central nervous system's ability to control ejaculation and reducing excitation of the nerves at the base of the penis, the effectiveness of neuromodulation approaches against premature ejaculation is improved and the risk of adverse reactions such as erectile dysfunction and loss of penile rigidity in patients is reduced, thus increasing the safety of using the neurostimulator.
[0054] In the neurostimulator according to the invention, electrical stimulation currents with mixed frequencies are used for electrical stimulation, whereby the treatment time is advantageously shortened to 30~60s per session and the effect is immediately noticeable after the treatment.
[0055] Although the present invention has been described in detail using exemplary embodiments, it will be understood by those skilled in the art that the invention is not limited to these exemplary embodiments. Rather, modifications are possible such that individual features can be omitted or different combinations of features can be implemented without exceeding the scope of the appended claims.
