In today's busy society, people's stress significantly affects their private lives. To make the sexual activity more fulfilling, a lot of sex toys are on the market to maintain and enhance people's interest and delight.
One common sex toy is the vibrator. However, a vibrator can only provide stimulation in the tactile sense, and has little effect on the male staying power, which is a major factor in satisfying intercourse.
To promote male endurance, there are also various medications on the market. However, these medications often contain intoxicant or harmful components, and usually cause undesirable side effects.
SUMMARY
Therefore, a desensitizing device is provided herein, which contains an electrical stimulation member. The electrical stimulation member is optionally configured on a support member. The electrical stimulation member contains a control circuit, and at least two electrodes. The control circuit produces a stimulating signal. The electrodes are configured to be attached to a user's skin and electrically connected to the control circuit to receive the simulating signal from the control circuit and to apply the stimulating signal to a subcutaneous nerve via the skin. The stimulating signal make the electrodes generate an electric field at least partially covering the subcutaneous nerve, and the magnitude of the electric field ranges from 100 V/m to 1000 V/m. When the simulating signal is applied, the subcutaneous nerve is temporarily desensitized to ease the neuralgia.
By applying the support member to the male genital, the electrodes will be in contact with the penis skin, the stimulating signal produced by the control circuit can then be conducted via the electrodes and provides a low-strength subcutaneous nerve stimulation through the penis skin. The subcutaneous nerve of the male genital is then numbed and desensitized temporarily, thereby prolonging the erection state of male genitals during intercourse. Since no medication is involved, no undesirable side effects from the medicine could take place.
In another scenario, the electrodes can also be applied to or near the body parts which suffers from pain. For example, if a user presents rheumatism at his/her elbow, he/she can apply the electrodes on the neural pathway between the spinal cord and his/her elbow.

DETAILED DESCRIPTION OF THE INVENTION
The embodiments of the invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
As shown in FIGS. 1 to 4, a desensitizing device according to a first embodiment of the present invention contains an electrical stimulation member 2, and a power supply unit 3. The electrical stimulation member 2 is optionally configured on a support member 1. The support member 1 can be ring-shaped or other appropriate shapes.
In the embodiment, the support member 1 has an outer circumference 11, an inner circumference 12, and a through channel 10 surrounded by the inner circumference 12. The support member 1 has an accommodation space 13 with a circular first opening on the outer circumference 11 sealed by a cover 14, and at least two linear second openings 131 on the inner circumference 12 so that the accommodation space 13 is connected to the through channel 10. The support member 1 is made of a flexible material and can be configured into a C-like shape with an axially-oriented linear opening 15 so that the linear opening 15 can be elastically broadened.
The electrical stimulation member 2 is housed in the accommodation space 13, and contains a control circuit 21, and at least two electrodes 22. The power supply unit 3 can contain a removable battery or a built-in rechargeable battery, and is electrically connected to the control circuit 21 so as to provide electricity to the control circuit 21. In the present embodiment, the power supply unit 3 contains a removable battery 32 and a battery chamber 31. The battery chamber 31 has a positive terminal and a negative terminal, both connected to the control circuit 21. The battery 32 is accommodated in the battery chamber 31 and the battery 32's positive and negative terminals are connected to the battery chamber 31's positive and negative terminals, respectively. The electrodes 22 are electrically connected to the control circuit 21, and are exposed to the through channel 10 on the inner circumference 12 through the second openings 131, respectively. With the electricity provided by the power supply unit 3, the control circuit 21 generates and delivers a stimulating current to the electrodes 22.
The stimulating current produced by the control circuit 21 can be a high-frequency signal between 200 KHz and 800 KHz, or a low-frequency signal between 0.5 Hz and 1 KHz (preferably between 2 Hz and 30 Hz), or a mixed signal with a high-frequency component and a low-frequency component, wherein the high-frequency component of the mixed signal is between 200 KHz and 800 KHz, and the low-frequency component of the mixed signal is between 0.5 Hz and 1 KHz (preferably between 2 Hz and 30 Hz). The high-frequency or low-frequency signal of the stimulating current can be a continuous wave or a train of pulses. The wave can be a sinusoidal wave, a triangular wave, a square wave, or one with an appropriately shaped waveform.
As the electrical stimulation member 2 is accommodated in the accommodation space 13, the control circuit 21 can be placed on a bottom side of the accommodation space 13. The electrodes 22 are electrically connected to a bottom side of the control circuit 21, configured in the second openings 131, respectively, and exposed from the inner circumference 12. The power supply unit 3 has the battery chamber 31 electrically connected to a top side of the control circuit 21, and the battery 32 is placed in the battery chamber 31. The first opening of the accommodation space 13 is then sealed by the cover 14 so that the electrical stimulation member 2 is tightly housed in the accommodation space 13.
The electrical stimulation member 2 further contains a switch 24 and an indicator lamp 25. The switch 24 is electrically connected to the control circuit 21 for turning the control circuit 21 on and off, and is exposed from the outer circumference 11 on the support member 1. The indicator lamp 25 is also electrically connected to the control circuit 21 and is exposed from the outer circumference 11 on the support member 1.
By threading a male genital through the through channel 10 of the support member 1 so that the electrodes 22 are in contact with the penis skin, the stimulating current produced by the control circuit 21 when the electrical stimulation member 2 is turned on is conducted by the electrodes 22 and provides a low-strength subcutaneous nerve stimulation through the penis skin. The subcutaneous nerve is as such temporarily numbed and desensitized, thereby enhancing the staying power of male genitals during intercourse. Since no medication is employed, potential undesirable side effects are avoided.
FIG. 5 depicts a second embodiment of the present invention. As illustrated, a desensitizing device of the present embodiment has an electrical stimulation member 2 configured on a belt-like support member 5. The support member 5 girdles a male genital so that the electrodes 22 of the electrical stimulation member 2 are in contact with the penis skin. The stimulating current produced by the control circuit 21 is conducted to the electrodes 22 and provides a low-strength subcutaneous nerve stimulation through the penis skin. The subcutaneous nerve is as such temporarily numbed and desensitized.
FIG. 6 depicts a third embodiment of the present invention. As illustrated, a desensitizing device of the present embodiment has an electrical stimulation member 2a that is applied independently without a support member or a power supply unit. In the embodiment, the two electrodes 22a of the control circuit 21a are configured in two flexible pads and extended by two transmission wires 211 so that the electrodes 22a can be attached to the penis skin directly. The stimulating current produced by the control circuit 21a is conducted to the electrodes 22a and provides a low-strength subcutaneous nerve stimulation through the skin. The subcutaneous nerve is as such temporarily numbed. In addition, the high-frequency simulating signal produced by the control circuit 21a can also be applied to other body parts (e.g., a wrist, an elbow, a head etc.) for low-strength subcutaneous nerve stimulation. In these applications, the electrodes 22a are attached directly to the desired body part. The stimulating signal produced by the control circuit 21a is conducted to the electrodes 22a and provides a low-strength subcutaneous nerve stimulation through the skin of the desired body part. The subcutaneous nerve is thereby temporarily numbed and desensitized so as to ease the neuralgia.
Please note that, the term “stimulating signal” used herein to refer to an electrical signal including voltage signal or current signal which can cause the electrodes 22a to generate an electric field. Reference to a particular type of electrical signal as being a stimulating signal is not intended to limit the scope of the claims unless a particular type of electrical signal is recited in the claims.
The stimulation signal is adapted to block the neurotransmission of the subcutaneous nerve. For example, if the stimulation signal is a voltage signal, the stimulating signal ranges from −10V to −1V or ranges from 1V to 10V. If the stimulation signal is a current signal, the stimulation signal ranges from 2 mA to 50 mA. For example, the stimulation signal is a voltage signal whose magnitude is 5V, or the stimulation signal is a current signal, the stimulation signal may be a 20 mA current signal.
Considering a case that the desensitizing device is used on dorsal penile verves, the distance between any adjacent two electrodes 22a ranges from 1 mm to 7 mm, the distance between each of the electrodes 22 and the subcutaneous nerve ranges from 0 to 10 mm, and the widths of the two electrodes 22a range from 3 mm to 10 mm, thereby when generated, the electric field at least partially covers the subcutaneous nerve which conducting the pain and has a magnitude ranging from 100 V/m to 1000 V/m, wherein the subcutaneous nerve is on the nerve conduction pathway between the spinal cord and locations effected.
Considering another case that the desensitizing device is used on median verves, the distance between any adjacent two electrodes 22a ranges from 5 mm to 60 mm, the distance between each of the electrodes 22 and the subcutaneous nerve ranges from 0 to 20 mm, and the widths of the two electrodes 22a range from 2 mm to 20 mm, thereby when generated, the electric field at least partially covers the subcutaneous nerve which conducting the pain and has a magnitude ranging from 100 V/m to 1000 V/m, wherein the subcutaneous nerve is on the nerve conduction pathway between the spinal cord and locations effected.
When applying the simulating signal to the subcutaneous nerve, the frequency of the stimulating signal could range from 200 KHz to 450 KHz or from 450 KHz to 550 KHz or from 550 KHz to 800 KHz, the subcutaneous nerve is temporarily desensitized and possibly eased from neuralgia. If the selected frequency is between 200 KHz˜450 KHz, the device operates in relatively low frequency so it is less risky to produce biological heat for better safety. Otherwise, if the selected frequency is between 550 KHz˜1000 KHz, the generated electric field has greater density so its electrical stimulation has better performance.
In addition, please refer to FIG. 7, which is a schematic diagram showing the wave form of the stimulation signal. In the embodiment, the stimulation signal outputted from the desensitizing device may be a continuous sine wave, a continuous triangular wave or a stimulation signal of high-frequency pulse. In the embodiment, the stimulation signal is a continuous sine wave and the magnitude of the signal is between +3.5V and −3.5V and the frequency of the stimulating signal is 500 KHz (1/Ts). One pulse cycle time Tp has a plurality of pulse signals and at least one period of rest time (Tp−Td). One pulse cycle time Tp is the reciprocal of pulse repetition frequency. The pulse repetition frequency (also called pulse frequency) is between 0˜1 KHz, preferably between 1˜100 Hz. In the embodiment, the pulse repetition frequency of the stimulation signal is about 2 Hz. Besides, the duration time Td of pulses in one pulse cycle time is between 1˜250 ms, preferably between 10˜100 ms. In the embodiment, it is 25 ms. By adjusting an operation duration time Td, the amount of the electrical stimulation is adjusted and the time for dissipating the produced biological heat accordingly. For example, if the stimulation intensity is relatively low, the duration time Td may be increased to continuously stimulate. If the stimulation intensity and the frequency are relatively high, the duration time Td may be decreased to raise the time for dissipating.
In other words, the electric field covers the subcutaneous nerve and its surroundings with low intensity, low temperature and high frequency simulating signal without damaging the neural cells of the subcutaneous nerve, thereby the biomolecular generation by the subcutaneous nerve is suppressed. Thus, the neurotransmission capability of the subcutaneous nerve in the target zone is lowered and the neurotransmission is blocked.

The field pattern of the electric field is adjusted by adjusting the distance A between the electrodes 22b, the distance B between skin surface and the dorsal penile nerve N (the circle portion), or the width C of the electrodes.

As shown in the FIG. 25, within the workable distance, in the experiment the distance A=40 mm, the distance B=5 mm and the width C is 20 mm, the electric field (the strength of the electric field is 100V/m˜150V/m) may only or mainly effectively cover the subcutaneous nerve N. Relatively, the electric field strength is more intense if the position is closer to the electrodes 22b.
Furthermore, please refer to FIG. 26, which is yet another schematic diagram of the electric field simulation of the desensitizing device when applying on a wrist. The field pattern of the electric field is adjusted by adjusting the distance A between the electrodes 22b, the distance B between skin surface and the median nerve N (the circle portion), or the width C of the electrodes. In the simulation experiment, the voltage of the stimulating signal is 5V, the frequency of the stimulating signal is 500 KHz. As shown in the FIG. 26, within the workable distance, in the experiment the distance A=40 mm, the distance B=5 mm and the width C is 5 mm, the electric field (the strength of the electric field is 100V/m˜150V/m) may only or mainly effectively cover the subcutaneous nerve N. Relatively, the electric field strength is more intense if the position is closer to the electrodes 22b.
