Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of underwear, and particularly to an erection detection method and underwear.
Background Art
[0002] Human sleep is always in alternation between the rapid eye movement (REM) sleep stage and the non-rapid eye movement (NREM) sleep stage, corresponding to experiencing the physiological processes of erection, flaccidity, re-erection, and re-flaccidity. This is called nocturnal penile tumescence (NPT) in medicine and is a normal physiological process for healthy men. Since the alternation of erection and flaccidity can promote blood circulation, bring oxygen, etc. and carry away metabolic wastes, nocturnal erection is sometimes also called the "charging mechanism" of the penis. Generally, men have 4 - 6 erections per night, each lasting 10 - 40 minutes, and the total erection time can reach two and a half hours.
[0003] Whether there is nocturnal erection is of great significance for judging the nature of erectile dysfunction in men when they are awake. If the erection is normal during sleep, it means that it is not an organic erectile dysfunction but there are other causes.
Summary of the Invention
[0004] To solve the above problem of detecting the erectile state of men at night, the present invention proposes an erection detection method and underwear that can monitor data on the nocturnal erectile state of men.
[0005] The present invention is realized by the following technical solutions:
[0006] An erection detection method and underwear, including the following steps:
[0007] Step S1: Detect erection. When the number of conduction of two opposite electrodes of the detection device increases sequentially, trigger the detection device to start acquiring signals;
[0008] Step S2: Signal output. The detection device outputs the signals to the signal collection device;
[0009] Step S3: Output erection data. The signal collection device transmits the data to the mobile device through the Bluetooth module;
[0010] Step S4: Evaluation result. When 3 < N < 7, the number of erections is normal. When T1 < 10s, the erection speed is normal. When 10min < T2 < 40min, the erection state is normal;
[0011] Among them, in step S2, the following steps are further included:
[0012] Step S201: Obtain time T1. Time T1 is the time from when the electrodes of the detection device start to conduct and output signals to when the detection device maintains stable signal output in step S1;
[0013] Step S202: obtaining time T2, where time T2 is the duration for which the detection device maintains outputting a stable signal, i.e., the duration for which the erection state is maintained;
[0014] Step S203: within a preset time, when two opposite electrodes of the detection device are turned on in sequence from bottom to top, return to step 1 and record the number of erections. After the preset time is over, proceed to the next step;
[0015] Step S204: Obtain the number of erections N, where N is the number of erections accumulated in step S203.
[0016] In the above-mentioned erection detection method, the step S1 further comprises:
[0017] Step S101: The detection device is provided with electrodes which are connected in parallel from bottom to top and remain normally off. When the electrodes which are connected in parallel and remain normally off are turned on from bottom to top, the male begins to have an erection, the number of parallel electrodes increases, and the total resistance decreases. When the resistance on the detection device decreases linearly in sequence, the male has a normal erection and proceeds to the next step. When the resistance on the detection device does not decrease linearly in sequence, the detection device misdetects a signal and the detection device stops detecting.
[0018] In the above-mentioned erection detection method, in step S101, the parallel resistance value is calculated according to the formula:
[0019] 1 / Rtotal=1 / R1+1 / R2+1 / R3+...+1 / Rn,
[0020] The more parallel electrodes are connected on the detection device, the smaller the output resistance signal is, and the longer the erection length is. The fewer parallel electrodes are connected on the detection device, the larger the output resistance signal is, and the shorter the erection length is.
[0021] In the above-mentioned erection detection method, step S201 comprises:
[0022] Step S2011: When the electrodes on the detection device begin to conduct and output signals to the signal collection device, the timing module on the signal collection device is triggered to start timing. When the detection device keeps outputting a stable signal, the timing module ends to obtain time T1.
[0023] In the above-mentioned erection detection method, step S202 comprises:
[0024] Step S2021: When the detection device starts to output a stable signal to the signal collection device, the timing module starts timing, and when the output stable signal changes, the timing module ends timing to obtain time T2.
[0025] An underwear, including an erection detection method as described above, further includes an underwear body, a detection device disposed in the crotch of the underwear body and used for detecting the erection state of a male, and a signal collection device electrically connected to the detection device and used for receiving the detection signal of the detection device. The detection device includes an interdigital electrode layer and a conductive layer. When the conductive layer closely adheres to and presses against the interdigital electrode layer, the two electrodes on the interdigital electrode layer that closely adhere to the conductive layer and are opposite to each other are electrically connected.
[0026] For the underwear as described above, the conductive layer is a graphene pressure-sensitive fabric.
[0027] For the underwear as described above, the interdigital electrode layer is provided with strip-shaped interdigital electrodes and a connection output terminal for connecting the interdigital electrodes and the signal collection device.
[0028] For the underwear as described above, the width range of the interdigital electrodes is 1 mm - 3 mm, and the width range of the connection output terminal is 10 mm - 20 mm.
[0029] For the underwear as described above, the interdigital electrode layer includes a working electrode and a counter electrode disposed opposite to the working electrode, and a gap is maintained between the working electrode and the counter electrode.
[0030] Compared with the prior art, the present invention has the following advantages:
[0031] 1. The present invention proposes an erection detection method, including the following steps:
[0032] Step S1: Detect erection. When the number of electrically connected pairs of electrodes of the detection device increases sequentially, trigger the detection device to start acquiring signals;
[0033] Step S2: Signal output. The detection device outputs the signal to the signal collection device;
[0034] Step S3: Output erection data. The signal collection device transmits the data to a mobile device through a Bluetooth module;
[0035] Step S4: Evaluate the result. When 3 < N < 7, the number of erections is normal. When T1 < 10 s, the erection speed is normal. When 10 min < T2 < 40 min, the erection state is normal;
[0036] Wherein, in step S2, the following steps are further included:
[0037] Step S201: Obtain time T1. Time T1 is the time from when the electrodes of the detection device start to be electrically connected and output signals to when the detection device maintains a stable output signal in step S1;
[0038] Step S202: obtaining time T2, where time T2 is the duration for which the detection device maintains outputting a stable signal, i.e., the duration for which the erection state is maintained;
[0039] Step S203: within a preset time, when two opposite electrodes of the detection device are turned on in sequence from bottom to top, return to step 1 and record the number of erections. After the preset time is over, proceed to the next step;
[0040] Step S204: Obtain the number of erections N, where N is the number of erections accumulated in step S203;
[0041] The present invention detects male nocturnal erections through step S1, outputs erection signals to a signal collection device through step S2, obtains the speed time T1 from non-erection to full erection, obtains the time T2 for maintaining full erection, and obtains the number of erections N, transmits the data collected by the signal collection device to a mobile device through step S3, and compares the detection data with normal erection data through step S4 to determine the male's erection health status.

When the conductive layer is tightly attached to and presses the interdigitated electrode layer, the two electrodes on the interdigitated electrode layer are tightly attached to the conductive layer and opposite to each other are turned on. When a male has an erection at night, the conductive layer is pressed against the conductive layer, so that the conductive layer is tightly attached to and presses the interdigitated electrode layer, so that the two electrodes on the interdigitated electrode layer are turned on. The signal collection device collects the signals of the turned-on electrodes, and then obtains the data of the male's nocturnal erection. In addition, the structure is simple, easy to wear, and the cost is lower, which can meet the needs of customers.

Specific Embodiment
[0049] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0050] Specific embodiments are as Figures 1 to 5 shown in an erection detection method, which includes the following steps:
[0051] Step S1: Detect erection. When the number of conducting electrodes on two opposite sides of the detection device increases in sequence, trigger the detection device to start acquiring signals;
[0052] Step S2: Signal output. The detection device outputs the signal to the signal collection device;
[0053] Step S3: Output erection data. The signal collection device transmits the data to the mobile device through the Bluetooth module;
[0054] Step S4: Evaluate the result. When 3 < N < 7, the number of erections is normal. When T1 < 10s, the erection speed is normal. When 10min < T2 < 40min, the erection state is normal;
[0055] Among them, in step S2, the following steps are further included:
[0056] Step S201: Obtain time T1. Time T1 is the time from when the electrodes of the detection device start to conduct and output signals to when the detection device maintains the output of stable signals in step S1;
[0057] Step S202: Obtain time T2. Time T2 is the duration of the detection device maintaining the output of stable signals, that is, the time of maintaining the erection state;
[0058] Step S203: Within a preset time, when the two opposite electrodes of the detection device conduct from bottom to top in sequence, return to step 1 and record the number of erections once. After the preset time ends, proceed to the next step;
[0059] Step S204: Obtain the number of erections N, where N is the cumulative number of erections in step S203;
[0060] The present invention detects male nocturnal erections through step S1, outputs erection signals to a signal collection device through step S2, obtains the speed time T1 from non-erection to full erection, obtains the time T2 for maintaining full erection, and obtains the number of erections N, transmits the data collected by the signal collection device to a mobile device through step S3, and compares the detection data with normal erection data through step S4 to determine the male's erection health status.
[0061] Furthermore, the step S1 further includes:
[0062] Step S101: The detection device is provided with electrodes which are connected in parallel from bottom to top and remain normally off. When the electrodes which are connected in parallel and remain normally off are turned on from bottom to top, the male begins to have an erection, the number of parallel electrodes increases, and the total resistance decreases. When the resistance on the detection device decreases linearly in sequence, the male has a normal erection and proceeds to the next step. When the resistance on the detection device does not decrease linearly in sequence, the detection device misdetects a signal and the detection device stops detecting. This is used to determine whether it is a normal erection state or a falsely connected state.
[0063] Furthermore, in step S101, the parallel resistance value is calculated according to the formula:
[0064] 1 / Rtotal=1 / R1+1 / R2+1 / R3+...+1 / Rn,
[0065] The more parallel electrodes are connected on the detection device, the smaller the output resistance signal is, and the longer the erection length is. The fewer parallel electrodes are connected on the detection device, the larger the output resistance signal is, and the shorter the erection length is.
[0066] Specifically, the step S201 includes:
[0067] Step S2011: When the electrodes on the detection device begin to conduct and output signals to the signal collection device, the timing module on the signal collection device is triggered to start timing. When the detection device keeps outputting a stable signal, the timing module ends to obtain time T1. When the parallel and normally off electrodes are turned on from bottom to top, the male begins to have an erection, the parallel electrodes increase, and the total resistance decreases. When the total resistance remains stable, the parallel electrodes no longer increase and a full erection state is reached. The timing module ends to obtain the speed time T1 from the non-erection state to the full erection state.
[0068] More specifically, the step S202 includes:
[0069] Step S2021: When the detection device starts to output a stable signal to the signal collection device, the timing module starts timing. When the stable output signal changes, the timing module ends timing to obtain time T2. When the total resistance remains stable, the parallel electrodes no longer increase, and the full erection state is reached, and the T1 time ends timing, the timing module starts timing again. When the output stable signal changes, that is, the parallel electrodes begin to decrease, the total resistance begins to increase, and the male penis begins to soften, the timing module ends timing, and the total time T2 to maintain the full erection state is obtained.
