Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a night penis swelling detection device based on a flexible sensor, a manufacturing method of the night penis swelling detection device and a night penis swelling detection system using the detection device.
Background
Penile erectile dysfunction is generally classified into psychological, organic and mixed disorders, with the psychological disorder accounting for the highest rate, and the clinical differentiation of different classes is of great significance for later treatment. Most of the clinical methods for detecting the penis distension at night are used to distinguish different categories. When the penis distention detection is carried out at night, the user needs to be subjected to hospitalization monitoring, for example, 1-2 nights of hospitalization, and a special detection instrument is used for acquiring necessary data, and the category of the user is judged according to the detected data.
At present, one device for detecting the swelling of the penis at night is a hardness scanner which can continuously record the change data of the circumference diameter and hardness of the penis, and when the device is used, two measuring metal rings are required to be respectively arranged at the root part and the coronary sulcus of the penis, and a recording device is fixed on the thigh and collects the data detected by the two metal rings at night.
Yet another prior art nocturnal penile erection system continuously measures changes in penile erection times, duration, length, circumference and blood volume. With this system, three electrodes are required to be placed on the root, coronary sulcus and ilium of the penis, respectively, and the recording device is required to be fixed on the thigh of the subject.
However, when the conventional night penis swelling detecting device is used, discomfort is easily generated, for example, the first scheme needs to sleeve two metal rings of the hardness scanner on the penis, so that strong discomfort is brought to the user, and the second method needs to directly generate voltage on the penis through the electrode, so that psychological discomfort is brought to the user.
In addition, the use safety of the conventional night penis swelling detecting device is also paid attention to by users, and the conventional night penis swelling detecting device is a reusable detecting device, so that the conventional night penis swelling detecting device has a hidden danger in terms of sanitation. In addition, since the metal ring of the hardness scanner of the first embodiment may not be loosened as the penis is changed when there is a problem in the contraction mechanism, the penis is tightened, resulting in pain to the user or inaccurate measurement; in the second scheme, when the electrode or the machine is in fault, the electrode or the machine is likely to generate larger stimulation to the human body, and the health of the human body is possibly damaged.
For this reason, some existing night penis swelling detecting devices are designed in the shape of underpants, for example, a flexible sensor for measuring the change of the length and hardness of the penis is provided, and the flexible sensor is provided in an elastic fabric, so that when the night penis swelling detecting device is used, a user wears underpants provided with the flexible sensor, and the user cannot see the flexible sensor because the sensor is wrapped by the elastic fabric, thus eliminating psychological obstacles of the user. However, in the night penis swelling detecting device, the flexible sensor is completely wrapped by the elastic fabric, but the elastic fabric is easy to deform under the action of external force, and the elastic fabric cannot be completely recovered due to the characteristics of the elastic fabric material, so that once the elastic fabric is stretched, the elastic fabric cannot be recovered to an initial state after stretching, the length of the flexible sensor is correspondingly prolonged, and errors exist in data acquired in the measuring process during subsequent use, so that the detecting accuracy is affected.
Some garments exist in which flexible sensors, such as flexible strain sensors sewn to an elastic fabric, are covered with a waterproof membrane. However, since the flexible strain sensor is also disposed on the elastic fabric, when the elastic fabric deforms and cannot be fully recovered, the strain sensor still cannot fully recover to the original state, and the detected data still cannot be accurate.
Disclosure of Invention
A first object of the present invention is to provide a night penis swelling detecting device based on a flexible sensor capable of improving detection comfort as well as detection accuracy.
A second object of the present invention is to provide a method for manufacturing the above-mentioned night penis swelling detecting device based on a flexible sensor.
A third object of the present invention is to provide a night penis swelling detecting system with the above-mentioned night penis swelling detecting device based on a flexible sensor.
In order to achieve the first object of the present invention, the night penis swelling detecting device based on the flexible sensor provided by the present invention includes a detecting portion formed in underpants, the detecting portion being cylindrical, wherein the detecting portion includes an elastic fabric layer, at least one sensor is formed on an outer surface of the elastic fabric layer, the sensor is annularly arranged along a circumferential direction of the detecting portion, and the sensor includes a conductive coating; the conductive coating is covered with a first elastic coating, a second elastic coating is formed on the inner surface of the detection part, and the second elastic coating is formed in a region of the inner surface corresponding to the conductive coating; the underpants are also provided with a data acquisition module, and the data acquisition module is electrically connected with the sensor through a wire.
As can be seen from the above-described solution, since the conductive coating layer of the sensor is covered by the first elastic coating layer and the second elastic coating layer, when the elastic fabric layer is stretched, even if the conductive coating layer is stretched, the elastic restoring force provided by the first elastic coating layer and the second elastic coating layer can restore the elastic fabric layer to the original state, so that the conductive coating layer is restored to the original state. When the conductive coating is stretched again, the conductive coating can also be stretched from an initial state, improving the accuracy of the measurement data.
In addition, the conductive coating is covered by the first elastic coating and the second elastic coating, so that the body of the user cannot be directly contacted with the conductive coating, and psychological barriers of the user can be eliminated. In addition, because the penis swelling detecting device at night can be made into the shape of underpants, the penis swelling detecting device can be used by a user only by wearing the underpants, and the penis swelling detecting device is very convenient to use.
In a preferred embodiment, the conductive coating is formed on the elastic fabric layer by a screen printing process; and/or the first elastic coating is formed on the conductive coating through a screen printing, spraying or knife coating process; and/or the second elastic coating is formed on the inner surface of the elastic fabric layer by a screen printing, spray coating or knife coating process.
Therefore, the screen printing, spraying or knife coating is a mature process, so that the manufacturing cost of the penis swelling detection device at night can be reduced by using the process, the stability of the conductive coating, the first elastic coating and the second elastic coating can be improved by using the mature process, and the problem that the conductive coating, the first elastic coating and the second elastic coating fall off is effectively avoided.
The conductive coating is prepared by mixing conductive particles and a high-molecular elastic material; and/or the conducting wire is made by mixing conductive particles and a high polymer elastic material.
Because the manufacturing materials of the conductive coating and the lead comprise high polymer elastic materials, the conductive coating and the lead can be quickly restored to the initial state after being elastically deformed, and the detection accuracy can be improved.
Still further, the first elastic coating and/or the second elastic coating are made of waterproof elastic materials.
Therefore, the first elastic coating and the second elastic coating can avoid the influence of the conductive coating on the detection accuracy caused by sweat and the like, and the penis swelling detection device can be repeatedly used after being washed at night.
In a further aspect, the number of the sensors is two or more, and the plurality of sensors are arranged at intervals in the axial direction of the detection portion.
Therefore, the two sensors arranged in the axial direction can detect the change of the circumference and the tension after the penis is inflated, so that more data can be acquired, and the subsequent analysis is facilitated.
In order to achieve the second object, the method for manufacturing a night penis swelling detecting device based on a flexible sensor according to the present invention includes manufacturing at least one sensor on an outer surface of an elastic fabric layer of a detecting portion of underpants: forming a conductive coating by a screen printing process: manufacturing a first elastic coating on the surface of the conductive coating, wherein the first elastic coating is covered on the conductive coating; manufacturing a second elastic coating on the inner surface of the detection part in a region corresponding to the conductive coating; the underpants are provided with a data acquisition module and a wire, so that the data acquisition module is electrically connected with the sensor through the wire.
According to the scheme, in the manufactured night penis swelling detection device, the sensor is covered by the first elastic coating and the second elastic coating, and after the elastic fabric layer is stretched to cause the sensor to be stretched, the sensor can be quickly restored to the initial state by the elastic restoring force provided by the first elastic coating and the second elastic coating, so that the detection accuracy is improved.
In a preferred scheme, after the conductive coating is formed by a screen printing process, the conductive coating is subjected to deformation pre-stretching treatment: the conductive coating is stretched to a preset multiple of the initial length.
By performing the deformation pre-stretching treatment on the conductive coating, the internal stress of the sensor can be improved, thereby improving the stability of the sensor. Since regular fine cracks will form in the conductive coating along the texture of the fabric after each stretch, the larger the stretch ratio, the larger the cracks and the more sensitive the sensor.
Further, the conductive coating is stretched to a preset multiple of the initial length for more than two times.
Therefore, the conductive coating is more obvious in crack formed after being stretched for multiple times through multiple times of deformation pre-stretching treatment, and the conductive coating is higher in sensitivity, and plays roles in controlling the sensitivity of the sensor and improving the stability through pretreatment.
Still further, the first elastic coating is formed on the conductive coating by a screen printing, spraying or doctor blading process; and/or the second elastic coating is formed on the inner surface of the elastic fabric layer by a screen printing, spray coating or knife coating process.
In order to achieve the third object, the night penis swelling detecting system based on the flexible sensor provided by the invention comprises data acquisition equipment and the night penis swelling detecting device based on the flexible sensor, wherein the data acquisition equipment acquires data acquired by the data acquisition module.

Detailed Description
The night penis swelling detecting system based on the flexible sensor comprises data acquisition equipment and a night penis swelling detecting device, preferably, the night penis swelling detecting device is formed on underpants, and a user wears the night penis swelling detecting device in a manner of wearing the underpants. The penis swelling detection device is provided with a sensor and a data acquisition module, the data acquisition module can send data acquired by the sensor to data acquisition equipment in a wireless mode, and the data acquisition equipment can be terminal equipment of a user, such as a smart phone and the like, and can also be a background server. The user can know the detection result through the terminal equipment, or the doctor can acquire the detection data of the user through the background server so as to analyze the detection result.
Referring to fig. 1, the night penis swelling detecting device of the present embodiment is provided on underpants 10, for example, the front end of underpants 10 is provided with a bag portion 12 and a detecting portion 11, the detecting portion 11 is located in front of the bag portion 12, after a user wears the underpants 10, the penis needs to be placed in the detecting portion 11, and the detecting portion 11 can tightly wrap the penis. As can be seen from fig. 1, the detecting portion 11 has a cylindrical shape, and preferably, the detecting portion 11 is made of an elastic fabric, and the night penis swelling detecting device of the present embodiment includes the detecting portion 11, that is, includes an elastic fabric layer.
Referring to fig. 2, two sensors 20 are formed on the detection portion 11, each sensor 20 having a circular ring shape, and each sensor 20 extending in the circumferential direction of the detection portion 11. Further, two sensors 20 are arranged at intervals in the axial direction of the detection portion 11, and each sensor 20 is connected to the data acquisition module 15 through a wire 30. The data acquisition module 15 is disposed on the underpants 10, for example, at a position near the top of the underpants 10, and the data acquisition module 15 is used for acquiring data acquired by the two sensors 20, for example, data changing in length along the axial direction, and the like. And, the data acquisition module 15 is provided with a wireless communication module, for example, a bluetooth module or a WIFI module, and through the wireless communication module, the data acquisition module 15 can send the data acquired by the two sensors 20 to a data acquisition device, and the data acquisition device can analyze the data of the sensors 20.
In this embodiment, each sensor 20 includes a conductive coating, and referring to fig. 3, the sensing part 11 of this embodiment is made of an elastic fabric, so that the night penis swelling detecting device includes an elastic fabric layer 16, and the conductive coating 22 is formed on the elastic fabric layer 16. Preferably, the conductive coating 22 is formed on the elastic fabric layer 16 by a screen printing process, and the conductive composite is formed by mixing conductive particles and a polymer material, wherein the conductive particles may be one or more of carbon black, graphene, metal particles, carbon nanotubes or various conductive fibers, and the polymer material may be a polymer material, such as one or more of silica gel, PU and EVA. For example, the composition of the conductive composite is as follows: comprises, by mass, 5% of carbon black, 3% of graphene and 92% of silica gel. Of course, in practical applications, the specific components and equipment of the conductive composite material can be adjusted according to practical needs.
The conductive composite material forms a conductive film on the outer surface of the elastic fabric layer 16 through a screen printing process, that is, forms the conductive coating 22, and because the conductive composite material contains a high polymer material with a relatively high specific gravity, particularly contains a material with high elasticity such as silica gel, the conductive coating 22 can generate transverse or longitudinal deformation when being stretched or compressed by external force, so that the resistance of the conductive coating 22 changes, and a stable corresponding relation is formed between the change rate of the resistance and the deformation of the conductive coating 22, and therefore, the deformation condition of the conductive coating 22 can be detected by detecting the resistance change condition of the conductive coating 22, for example, the length change condition of the conductive coating 22 is detected.
As can be seen from fig. 1, the conductive coating 22 is disposed in a circular ring shape in the circumferential direction of the detecting portion 11, and preferably, the conductive coating 22 is disposed on the outer surface of the elastic fabric layer 16, that is, the surface that is not in contact with the human body. Since the penis is placed in the detecting portion 11, when the penis is inflated, the circumference of the conductive coating 22 is changed, for example, the circumference is lengthened, and the change of the circumference after the penis inflation can be calculated by detecting the length change value of the conductive coating 22. When the penis is retracted, the conductive coating 22 also follows the retraction, and the circumference of the conductive coating 22 changes.
Since the conductive coating 22 is formed on the elastic fabric layer 16, when the conductive coating 22 is deformed, the elastic fabric layer 16 is deformed synchronously, but after the elastic fabric layer 16 is deformed, it is difficult to recover to the original state, and the conductive coating 22 is formed on the elastic fabric layer 16 by screen printing, once the elastic fabric layer 16 cannot recover to the original state, the conductive coating 22 cannot recover to the original state. Since the penis is often inflated and retracted a plurality of times during the detection of the penis inflation at night, once the conductive coating 22 cannot be restored to the original state, the detection result at the next inflation of the penis will be affected, resulting in the occurrence of inaccurate detection.
For this purpose, the first elastic coating layer 23 is disposed above the conductive coating layer 22 in this embodiment, and as can be seen from fig. 3, the first elastic coating layer 23 is disposed on the surface of the conductive coating layer 22 remote from the elastic fabric layer 16. For example, the first elastic coating 23 may be disposed on the surface of the conductive coating 22 by a screen printing, spraying or knife coating process. Preferably, the first elastic coating 23 completely covers the surface of the conductive coating 22.
And, a second elastic coating 24 is provided on the inner surface of the elastic fabric layer 16, i.e., the surface remote from the first elastic coating 23, the second elastic coating 24 is provided on the region corresponding to the conductive coating 22, i.e., the region provided with the conductive coating 22, and the second elastic coating 24 is provided on the inner surface of the elastic fabric layer 16. Like the first elastic coating 23, the second elastic coating 24 is also provided on the surface of the elastic fabric layer 16 by a screen printing, spraying or knife coating process.
Preferably, the first elastic coating layer 23 and the second elastic coating layer 24 are made of a material having high rebound resilience, for example, silicone rubber. Thus, the upper and lower sides of the conductive coating 22 are completely covered with the first and second elastic coatings 23 and 24. The elastic restoring force can be applied to the conductive coating 22 through the first elastic coating 23 and the second elastic coating 24, when the length of the conductive coating 22 changes under the action of external force, after the external force disappears, the conductive coating 22 has the elastic restoring force, and the elastic restoring force can be applied to the conductive coating 22 by the first elastic coating 23 and the second elastic coating 24, so that the sensor can rebound rapidly after being stretched each time, and the detection precision of the sensor is improved. For example, when the penis is retracted after swelling, the conductive coating 22 can be quickly restored to the original state, thereby providing an accurate detection basis for the next detection.
Further, the first elastic coating layer 23 and the second elastic coating layer 24 are made of a material having waterproof performance, for example, silica gel is used in the present embodiment. Since the conductive coating 22 will crack along the texture of the fabric after being stretched, sweat or moisture will directly affect the resistance of the conductive coating 22 after entering the cracks, thereby reducing the accuracy of strain measurement of the conductive coating 22, and in severe cases, the conductive coating 22 will fail and fail to work properly. The first elastic coating 23 and the second elastic coating 24 have waterproof performance, and can prevent moisture from penetrating into cracks, so that the reliability of the conductive coating 22 is improved. In addition, since the night penis swelling detecting means is actually formed on the underpants 10 and can be reused, the underpants can be washed for reuse after the first and second elastic coatings 23, 24 are provided.
The night penis swelling detecting means can detect a change in distance between the two sensors 20 when the penis swells, in addition to a change in circumference when the penis swells by the two sensors 20. For example, a wire 30 is provided between two sensors 20 and the data acquisition module 15, the length of the wire 30 provided between one sensor 20 and the data acquisition module 15 is different from the length of the wire 30 provided between the other sensor 20 and the data acquisition module 15, and if the length of the wire 30 provided between one sensor 20 and the data acquisition module 15 is L1 and the length of the wire 30 provided between the other sensor 20 and the data acquisition module 15 is L2, the change in length at the time of penis expansion can be calculated by detecting the change in the difference between the length L1 and the length L2.
For this reason, the wire 30 of the present embodiment is a flexible wire formed on the detecting portion 11, and preferably, the wire 30 is made of the same material as the conductive coating 22 and is also formed on the outer surface of the elastic fabric layer 16 using a screen printing process. The length of the lead 30 will lengthen when the penis is inflated and the length of the lead 30 will retract when the penis is retracted. Further, an elastic coating layer may be formed on the surface of the conductive wire 30, and another elastic coating layer is provided on the inner surface of the elastic fabric layer 16 in the region corresponding to the conductive wire 30, similarly to the manner in which the first elastic coating layer 23 and the second elastic coating layer 24 are provided on the upper and lower sides of the conductive coating layer 22. In this way, the elastic coatings on the upper side and the lower side of the wire 30 provide sufficient elastic restoring force for the wire 30, and prevent the wire 30 from being infiltrated by moisture, such as affecting the detection accuracy.
Of course, if it is not necessary to detect the change in length after the penis is inflated, it is not necessary to provide elastic coatings on the upper and lower sides of the lead 30, and only a flexible lead may be provided.
The wire 30 transmits the data acquired by the two sensors 20 to the data acquisition module 15, and the data acquisition module 15 may transmit the data to a data acquisition device, such as a user's terminal device or a background server of a hospital, through a wireless communication module. In this embodiment, the data acquisition module 15 may be sewn to the top of the undergarment 10.
Referring to fig. 4, the data acquisition device 40 acquires data acquired by the sensor 20 through the data acquisition module 15, for example, the data acquisition device 40 is a smart phone of a user, an APP is installed on the smart phone, and the user acquires detection data through the APP. Preferably, the detection data can be synchronized to a cloud server, and a doctor analyzes the detection data through the cloud server to confirm the type of the user and give a treatment scheme and advice in a targeted manner.
Further, the data acquisition device 40 may perform continuous machine learning according to the detection data and rehabilitation scheme of the user, optimize the therapeutic scheme according to the feedback data of the user, push different science popularization knowledge and therapeutic scheme for the user according to the diagnosis report, and form a big data algorithm to provide more convenient service for doctors and users.
In manufacturing the night penis swelling detecting device, it is first necessary to determine the specific arrangement position of the sensor 20 on the underpants with the detecting section 11, and then the outer surface of the elastic fabric layer 16 is formed with the conductive coating 22 by a screen printing process or the like. The conductive coating 22 is then subjected to a large deformation pre-stretching treatment. The present embodiment performs the pre-stretching treatment in order to enhance the stability of the conductive coating 22 and to control the sensitivity of the conductive coating 22, i.e., the sensitivity factor GF (Gauge Factor). Typically, the sensitivity factor = Δr/Δε (i.e., the rate of change of resistance per unit strain, where Δr is the change in resistance, Δε strain).
The pre-stretching treatment may be performed by a universal material testing apparatus, specifically, first fixing two ends of the conductive coating 22 to two jigs of the material testing apparatus, and then stretching the conductive coating 22 by moving the two jigs, so that the length of the conductive coating 22 is a preset multiple of the initial length, for example, stretching to between 1.5 and 3 times of the initial length, and the number of stretching may be one or more times. Of course, the number of stretching and the multiple of stretching can be adjusted according to actual requirements. The internal stress of the conductive coating 22 can be eliminated by performing the stretching treatment, the stability of the conductive coating 22 can be improved, and in addition, the sensitivity of the conductive coating 22 can be regulated. Specifically, by stretching the conductive coating 22 a preset number of times to deform the conductive coating 22, regular fine cracks are formed along the texture of the fabric on the surface of the conductive coating 22; the larger the multiple of stretching, the larger the crack and the more sensitive the conductive coating 22 will be, so that the conductive coating 22 can detect even smaller deformations. By controlling the magnitude of the pre-stretching force, cracks with different sizes are generated, so that the sensitivity of the conductive coating 22 can be controlled by the stretching force, namely the stretching multiple, so as to meet the use requirements of different application scenes.
After the conductive coating 22 is formed, it is also necessary to form the first elastic coating 23 on the surface of the conductive coating 22 by a process such as screen printing, spraying or knife coating, and form the second elastic coating 24 on the inner surface of the detecting portion 11 in the region corresponding to the conductive coating 22. Finally, the underpants 10 are provided with a data acquisition module 15 and a wire 30, so that the data acquisition module 15 is electrically connected with the sensor 20 through the wire 30. Of course, elastic coatings may be provided on both the upper and lower sides of the wire 30.
Since the conductive coating is arranged on the detection part through a simple process and the conductive coating is covered by the elastic coatings on the two sides, the embodiment provides enough elastic restoring force for the conductive coating and can improve the detection accuracy of the penis swelling detection device at night. In addition, because the first elastic coating and the second elastic coating also have waterproof performance, sweat and the like are prevented from penetrating into the conductive coating to influence detection accuracy, and on the other hand, the water washing of the penis swelling detection device at night can be realized so as to be convenient for repeated use.
Finally, it should be emphasized that the invention is not limited to the above embodiments, for example, the changes in the specific components of the conductive composite material used to make the conductive coating, or the changes in the stretching ratio and the number of stretching times when the deformation pre-stretching treatment is performed, and these changes should also be included in the protection scope of the claims of the invention.
