Description

Technical Field

[0001] This invention patent relates to the technical field of male products, specifically to a penile erection length measuring tool and a condom. Background Technology

[0002] Among various contraceptive methods, male condoms are one of the most widely used and popular due to their convenience and effectiveness. Current male condoms are generally manufactured by rolling the condom itself into a ring and sealing it. To use, carefully pinch the small pouch at the end with your fingers to expel air, then place it on the glans penis, and then unroll it upwards with your fingers until it reaches the base of the penis to complete the insertion.

[0003] Based on clinical experience in andrology, men seeking treatment are generally concerned about the length of their erect penis and experience some degree of size anxiety. The commonly used method of direct measurement with a ruler often yields inaccurate data due to factors such as unfriendly measuring tools, insufficient penile erection, or incorrect measurement techniques, causing further worry and distress for patients. Ordinary condoms generally cannot measure length; even those that do rely on external markings, requiring careful handling during insertion to avoid inaccurate readings, thus presenting numerous inconveniences in use.

[0004] Therefore, there is a need for a user-friendly, convenient, accurate, and practical tool and method for measuring penis length. Summary of the Invention

[0005] The purpose of this invention is to provide a penile erection length measuring tool and a condom. The tool measures the length of the erect penis through a thread-based measuring mechanism. The thread is black during measurement, and its color changes when the penis heats up, making it easy for the observer to distinguish. The measurement is completed by directly reading the scale on the thread. This invention is convenient to use and aims to solve the problem in existing condoms that measure length by external scales, which requires careful handling during wear to avoid deviations and inaccurate measurements.

[0006] This invention is implemented as follows: a penile erection length measuring tool includes a fixing ring that fits over the glans penis. Guide plates are provided at both ends of one side of the fixing ring. A thread measuring mechanism is provided on each guide plate. The thread measuring mechanism includes a thread, one end of which is attached to the fixing ring, and the other end passes through the guide plate and connects to a rotating sleeve. A scale is provided on the thread, and a thermosensitive color-changing layer is provided below the scale. When the thread contacts the penis for measurement, the thermosensitive color-changing layer changes color due to heat. The penile length is then measured by reading the scale value on the color-changing thread.

[0007] Furthermore, the guide plate includes an arc-shaped portion and an extension portion, the arc-shaped portion being connected to a fixing ring, and the arc-shaped portion bending outward and its end intersecting the tangent of the outer diameter of the fixing ring.

[0008] Furthermore, the extension is connected to the arc-shaped portion, and a guide sleeve is provided at the end of the extension, through which the line passes and connects to the rotating sleeve.

[0009] Furthermore, a connecting rod is sleeved in the middle of the rotating sleeve, and both ends of the connecting rod are fixed inside the fixing plate. The excess part of the wire is wound around the rotating sleeve so as to adjust it by measuring different lengths.

[0010] Furthermore, a connector is provided on the outer edge of the rotating sleeve, and a connection hole is provided on the connector. The end of the wire is inserted into the connection hole to fix it to the connector.

[0011] Furthermore, each of the two guide plates has a wire laying section on one side facing each other, and each of the wire laying sections has an oblique section on both sides. The wire is laid from the wire laying section and connected to the rotating sleeve. The oblique section realizes that the width of the guide plate decreases sequentially from the outside to the wire laying section.

[0012] Compared with the prior art, the penile erection length measuring tool and condom provided by the present invention have the following beneficial effects:

[0013] 1. The length of the erect penis is measured by a thread measuring mechanism. The thread is black during measurement. When the penis heats up, the color of the thermosensitive color-changing layer changes, making it easy for the observer to distinguish. After identification, the degree is measured by reading the scale on the thread. It is convenient to use and has high measurement accuracy.

[0014] 2. The thread is passed through the thread laying section, which allows the thread to directly contact the penis during measurement, thereby quickly triggering the thermochromic layer to change color. At the same time, for threads of different lengths, the thread length is increased by rotating the thread on the rotating sleeve, ensuring that the thread can contact the penis inside the elastic sleeve. Threads not bound by the elastic ring cannot sense temperature changes and will not change color, thus ensuring the accuracy of the measured length value.

[0015] A condom includes an elastic sheath, a liquid sac on one side of the elastic sheath, an elastic ring on the other side of the elastic sheath, and a penile erection length measuring tool fixed inside the condom.

[0016] Specifically, the fixing ring is located on the side of the elastic sleeve located in the liquid bladder, and the outer wall of the fixing ring abuts against the inner wall of the elastic sleeve to achieve fixation.

[0017] Specifically, the arc-shaped part fits against the inner wall of the elastic sleeve, and the thread passes through the fixed ring sequentially to the outside of the elastic ring and connects with the rotating sleeve.

[0018] Specifically, the thermochromic layer changes color from black to white when heated. Attached Figure Description

[0029] Reference Figure 1-5 As shown, the penile erection length measuring tool includes a fixing ring 1 that fits over the glans penis. Guide plates 2 are located at both ends of one side of the fixing ring 1. A thread measuring mechanism 3 is mounted on the guide plates 2. The thread measuring mechanism 3 includes a thread 31, one end of which is mounted on the fixing ring 1, and the other end passes through the guide plates 2 and connects to a rotating sleeve 34. A scale 39 is set on the thread 31, and a thermosensitive color-changing layer 310 is located below the scale 39. When the thread 31 contacts the penis for measurement, the thermosensitive color-changing layer 310 changes color due to heat. The value of scale 39 on the color-changing thread is then read to determine the penile length. The thread measuring mechanism 3 enables the measurement of the length of the erect penis. The color change of the thermosensitive color-changing layer 310 due to the heat generated by the penis facilitates observation. After identification, the measurement is completed by directly reading the scale 39 on the thread 31. The tool is convenient to use and offers high measurement accuracy.

[0030] In this embodiment, the guide plate 2 includes an arc-shaped portion 21 and an extension portion 22. The arc-shaped portion 21 is connected to the fixing ring 1, and the arc-shaped portion 21 bends outward and its end intersects the tangent of the outer diameter of the fixing ring 1. The arc-shaped portion 21 increases the supporting inner diameter of the guide plate 2, thus providing a supporting effect for the condom. The extension portion 22 is connected to the arc-shaped portion 21, and a guide sleeve 36 is provided at the end of the extension portion 22. The thread 31 passes through the guide sleeve 36 and is connected to the rotating sleeve 34. The guide sleeve 36 has a local limiting effect on the thread 31, thereby ensuring that the thread 31 passing through the guide plate 2 does not deviate. In addition, the thickness of the guide plate 2 is small and almost negligible inside the condom. Therefore, this device will not cause any trouble for the use of the condom.

[0031] In this embodiment, a connecting rod 33 is sleeved in the middle of the rotating sleeve 34. Both ends of the connecting rod 33 are fixed inside the fixing plate 32. The excess part of the wire 31 is wound around the rotating sleeve 34 to allow for measurement and adjustment at different lengths. A connecting piece 35 is provided on the outer edge of the rotating sleeve 34. The connecting piece 35 has a connecting hole. The end of the wire 31 is inserted into the connecting hole to fix it to the connecting piece 35. The rotating sleeve 34 can rotate on the connecting rod 33, thereby allowing the wire 31 to be stretched for easy measurement. At the same time, the end of the wire 31 is fixed on the connecting piece 35, thus ensuring that the rotating sleeve 34 will not separate from the wire 31.

[0032] In this embodiment, each of the two guide plates 2 has a wire laying section 38 on one side facing each other, and an oblique section 37 is provided on both sides of the wire laying section 38. The wire 31 is laid from the wire laying section 38 and connected to the rotating sleeve 4. The oblique section 37 makes the width of the guide plate decrease sequentially from the outside to the wire laying section 38. The wire 31 passes through the wire laying section 38. The wire laying section 38 makes it easy for the wire 31 to directly contact the penis during measurement, thereby quickly triggering the thermochromic layer 310 to change color. At the same time, for wires of different lengths, the length of the wire 31 is increased by rotating the wire 31 on the rotating sleeve 34, so as to ensure that the wire 31 can contact the penis inside the elastic sleeve 4.

[0033] Reference Figure 6 As shown, the condom includes an elastic sheath 4, a liquid sac 5 on one side of the elastic sheath 4, and an elastic ring 6 on the other side. A penile erection length measuring tool is fixed inside the condom. A fixing ring 1 is located on the side of the elastic sheath 4 where the liquid sac 3 is located, and the outer wall of the fixing ring 1 abuts against the inner wall of the elastic sheath 4 for fixation. The arc-shaped part 21 fits against the inner wall of the elastic sheath 4. A thread 31 passes through the fixing ring 1 and extends to the outside of the elastic ring 6 to connect with the rotating sleeve 4. This causes the thread to change color due to the heat of the penis during use. After use, the thread 31 can be observed, and the length of the penis during erection can be read through the scale 39.

[0034] In addition, since the fixing sleeve 1 will come into contact with the glans, the length of the glans will be ignored. The starting point of the line 31 in this technical solution is not 0mm, but 1-2mm. This ensures that the glans part in front of the fixing sleeve 1 will not be ignored, so as to achieve the accuracy of measuring the length of the penis.

[0035] This technical solution measures the length of an erect penis using a thread measuring mechanism 3. The thread 31 used for measurement is black and passes through a thread laying section 38, which allows the thread 31 to directly contact the penis during measurement. For different lengths, the thread 31 is rotated on a rotating sleeve 34 to increase its length, ensuring it contacts the penis inside the elastic sleeve 4. The thread 31 not bound by the elastic ring 6 cannot sense temperature changes and therefore will not change color, ensuring the accuracy of the measured length. When the penis heats up, the thermochromic layer 310 changes color from black to white, making it easy for the observer to distinguish. After differentiation, the measurement is completed by reading the scale 39 on the thread 31, resulting in high accuracy.

[0036] Specifically, the thermochromic layer 310 is made of thermochromic pigment, which is prepared from an electron transfer type organic compound system. Electron transfer type organic compounds are a class of organic chromogenic systems with special chemical structures. At a specific temperature, electron transfer causes changes in the molecular structure of the organic compound, thereby achieving a color change. This type of chromogenic substance not only has a bright color but can also achieve a color change from a "colored → colorless" state, which is not possessed by heavy metal complex salt type and liquid crystal type reversible thermochromic substances. Therefore, the thermochromic layer 310 is already common knowledge, and its working principle and preparation method do not need to be explained in detail.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
