Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a gravity-driven method and apparatus for measuring penile size. Background Technology

[0002] The healthy development of the reproductive organs in children and adolescents is a crucial aspect of pediatric and urological clinical diagnosis and treatment. Statistics show that approximately 2% of children and adolescents present with concealed penis, in addition to other reproductive organ malformations or diseases. After surgical or other treatments for these conditions, objective and quantitative data are needed for efficacy evaluation and long-term monitoring. Simultaneously, parents' demand for daily monitoring of their children's reproductive organ development is also increasing.

[0003] Currently, the tools used to measure the size of a child's penis (mainly length and circumference) are mostly ordinary rulers or tape measures. These general measuring instruments have obvious technical defects and limitations, and cannot meet the needs of professional and standardized measurement. Specifically, they are manifested in the following aspects: First, regarding baseline positioning, the lack of a dedicated positioning design adapted to the anatomical structures of children, such as the sacrum and scrotum, means that determining the measurement starting point (e.g., the pubic symphysis) relies entirely on manual pressure and visual judgment, making it highly susceptible to inconsistencies in baselines due to factors such as changes in the child's position and operator angle deviations. Second, in terms of measurement process and accuracy, length measurement requires external force for positioning, which can easily deform the penis and affect the reading due to the viewing angle. Circumference measurement relies on manually wrapping a soft measuring tape, with the tightness depending entirely on the operator's subjective feel, lacking a unified mechanical standard, resulting in poor data repeatability and low comparability, failing to meet the stringent accuracy requirements of clinical diagnosis. Third, in terms of ease of operation and integration, length and circumference measurements require changing different tools, making the process cumbersome and inefficient. Finally, regarding safety and user experience, the sharp edges and corners of general-purpose tools pose a risk of scratching, and their cold material and discomfort can easily cause fear and resistance in children, affecting the smooth progress of the measurement. Therefore, we provide a gravity-driven penile size measurement method and device. Summary of the Invention

[0004] The purpose of this invention is to provide a gravity-driven method and apparatus for measuring penis size, in order to solve the problems mentioned in the background art, such as inconsistent measurement benchmarks, poor positioning stability, susceptibility to human interference during the measurement process, difficulty in guaranteeing accuracy, cumbersome operation, lack of integrated design, and insufficient consideration of safety and comfort.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gravity-driven method for measuring penis size, comprising the following steps: S1. Measurement Preparation: The upper and lower parts of the measuring cylinder are assembled and fixed by a snap-fit ​​connection structure, ensuring that the slider is in the initial position of the slide groove and the flat cloth strip is in the storage state; S2. Measure penis length: S2.1. Position the child being tested in a comfortable position, place the arc-shaped fitting part at the top of the measuring cylinder against the sacrum, and fit the elliptical receiving space at the front end against the scrotum, so that the axis of the measuring cylinder is parallel to the axis of the penis, thus completing the positioning. S2.2 Raise the end of the measuring cylinder so that the slider slides naturally downward along the groove under its own weight and the action of the built-in counterweight; S2.3 After the front end of the slider has fully contacted the head of the penis and stopped sliding, read the corresponding value on the scale line on the outside of the slide groove through the pointers on both sides of the slider. This value is the length of the penis. S3. Measure penile circumference: S3.1 Adjust the base of the penis to the measurement area corresponding to the circumference measurement component; S3.2 Hold the flat cloth strip from one end of the hole structure and slowly pull the receiving cavity box to make it slide along the preset channel, while at the same time driving the flat cloth strip to slowly wrap around the base of the penis; S3.3 Continuing to pull until the preset mark is exposed inside the receiving cavity, at this time the flat cloth strip completely wraps the base of the penis with uniform tightness under the action of the spring pull. Read the corresponding scale value on the flat cloth strip through the hole structure. This value is the circumference of the base of the penis. S4. Measurement complete: Slide the slider back to its original position, retract the flat cloth strip, and disassemble the measuring cylinder through the buckle connection structure for cleaning and disinfection.

[0006] The present invention also provides a penis size measuring device, including a measuring cylinder, the upper end of which is provided with an arc-shaped fitting part adapted to the child's sacrum, the front end of which is provided with an elliptical receiving space adapted to the child's scrotum, and the measuring cylinder is provided with a measuring component for measuring the length and circumference of the child's penis. The measuring component includes a groove opened along the axial direction of the measuring cylinder, a slider that can slide in the groove, and scale lines engraved on the outside of the groove. The slider has pointers fixed on both sides for pointing to the scale lines. The measuring assembly also includes a housing with a built-in spring, a flat cloth strip with one end fixedly connected to the spring and the other end extending out of the measuring cylinder, and a perforated structure through which the flat cloth strip passes, the surface of which is engraved with a circumference scale.

[0007] Preferably, the measuring cylinder body is made of medical-grade non-toxic material and is detachable and assembleable through a snap-fit ​​connection structure.

[0008] Preferably, the inner surface of the groove is frosted to improve the damping effect, and the slider is provided with a counterweight to cooperate with its own weight to ensure smooth and stable sliding.

[0009] Preferably, the circumference scale of the flat cloth strip has a range of 0-130mm, and its starting scale is adapted to the wall thickness of the measuring cylinder body.

[0010] Preferably, the measuring cylinder, slider, and all other parts that come into contact with the human body are designed with rounded transitions and no sharp angles.

[0011] Preferably, the cross-section of the groove is T-shaped, and the slider is provided with a sliding part that matches the shape of the groove, forming an anti-derailment structure.

[0012] Preferably, the side wall of the receiving cavity is provided with a visualization window, and a preset mark is located on the inner wall of the receiving cavity. When the flat strip is pulled to move the preset mark to be aligned with the visualization window, it indicates that the standard tightness measurement has been achieved.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This gravity-driven penile size measurement method and device, through its unique "human-adaptive positioning structure," forcibly unifies the professional measurement benchmark from the pubic bone to the glans penis, ensuring the stability of the positioning and eliminating benchmark errors caused by changes in body position and manual operation. The length measurement adopts a gravity-driven slider that slides naturally, avoiding external force interference and data distortion caused by manual pressing. The circumference measurement uses a spring to provide uniform pull force and is supplemented by preset markings, achieving standardization of the tightness of the wrapping, so that the obtained length and circumference data have high accuracy and repeatability.

[0014] 2. This gravity-driven penile size measurement method and device, through ingenious integrated design, combines length and circumference measurement functions into one. The operation process is simplified to four intuitive steps: "positioning, sliding, pulling, and reading." Without changing tools, parents or medical staff can quickly and easily complete the entire measurement by themselves, improving efficiency in home and clinical settings. In terms of safety, all parts in contact with the human body adopt a rounded transition design and are made of medical-grade non-toxic materials, fundamentally eliminating the risk of scratching children. At the same time, the gravity-driven and spring-pull measurement method is very gentle, reducing children's fear and resistance, making the measurement process smoother and improving the overall comfort experience.

[0015] 3. This gravity-driven penile size measurement method and device has a compact and simple overall structure, small size, and is easy to carry and store. Its snap-on detachable design makes cleaning and disinfection extremely convenient, meets the hygiene requirements for repeated use, and reduces long-term use costs. The design is suitable for the entire developmental cycle of children and adolescents aged 3-18 and can be widely used in various scenarios such as daily home monitoring, hospital clinical examinations, and school health checkups. In addition, the device does not require complex electronic components, has a simple structure, low manufacturing cost, and stable supply of selected materials, which is conducive to large-scale production and promotion and application at all levels of society.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Example 1:

[0022] See Figures 1-6 A penis size measuring device includes a measuring cylinder 1, the upper end of which has an arc-shaped fitting part adapted to the sacrum of a child, and the front end has an oval-shaped receiving space adapted to the scrotum of a child. The main body of the measuring cylinder 1 is made of medical-grade non-toxic material, which ensures biocompatibility when in contact with the child's skin, avoids allergic or toxic reactions, significantly improves the safety of use, and can be disassembled and assembled through a snap-fit ​​connection structure, which facilitates thorough cleaning and disinfection after each measurement, meets the hygiene requirements for repeated use, reduces the risk of cross-infection, and enhances the portability and storage of the device. The measuring cylinder 1 is equipped with a measuring component for measuring the length and circumference of the child's penis.

[0023] The measuring assembly includes a groove 2 extending axially along the measuring cylinder 1, a slider 3 that slides within the groove 2, and graduation lines 4 engraved on the outer side of the groove 2. Pointers 5 for pointing to the graduation lines are fixed to both sides of the slider 3. The measuring cylinder 1, slider 3, and all other parts in contact with the human body feature a rounded transition design with no sharp angles, avoiding the risk of scratches from sharp edges that may exist with traditional tools. This design is especially suitable for children with sensitive skin, reducing discomfort and fear during measurement. The rounded shape conforms to the human body's curves, enhancing comfort and making it easier for children to cooperate, thus improving measurement efficiency. Simultaneously, this design meets the safety standards for medical devices, reducing external interference through gentle contact and ensuring data accuracy. Overall, the rounded transition not only protects the user but also reflects the device's human-centered design philosophy, making it suitable for home and clinical settings. The inner surface of the groove 2 is frosted to improve damping efficiency. To prevent the slider 3 from sliding too quickly or wobbling due to inertia and to ensure a stable and controllable measurement process, a counterweight is installed inside the slider 3 to assist its own weight in ensuring smooth and stable sliding, eliminating external interference, making the contact between the slider 3 and the head of the penis soft, and improving the child's comfort. The combination of frosted surface and counterweight enhances the mechanical reliability of the device, making the measurement data more objective and suitable for children in different positions. The cross-section of the slide groove 2 is "T"-shaped. The "T"-shaped channel increases the contact area and improves mechanical strength, allowing the slider 3 to slide naturally with the assistance of the counterweight without external intervention, enhancing the repeatability and objectivity of length measurement. The slider 3 has a sliding part that matches its shape to form an anti-derailment structure, ensuring the stability and reliability of the slider 3 during the sliding process, preventing the slider 3 from derailing or getting stuck under gravity, ensuring its smooth sliding along the slide groove 2, and reducing measurement errors.

[0024] Example 2:

[0025] See Figures 1-6 Based on Example 1, this example simultaneously measures the circumference of a child's penis to further improve the measurement experience and accuracy.

[0026] The measuring assembly also includes a receiving cavity 6 with a built-in spring 7, a flat cloth strip 8 with one end fixedly connected to the spring 7 and the other end extending out of the measuring cylinder 1, and a hole structure 9 for the flat cloth strip 8 to pass through. The surface of the flat cloth strip 8 is engraved with a circumference scale. The side wall of the receiving cavity 6 is provided with a visualization window, which makes the operation intuitive and easy to read, reduces misjudgment, and is suitable for non-professionals. The preset mark is located on the inner wall of the receiving cavity 6. When the flat cloth strip 8 is pulled to move the preset mark to align with the visualization window, it indicates that the standard measurement tightness has been reached. The preset mark serves as a mechanical stop point to ensure that the measurement conditions are consistent each time, enhance the reliability of clinical data, and simplify the complex process to "pull-align-read". This improves efficiency while taking into account the comfort of children. The circumference scale of the flat cloth strip 8 has a range of 0-130mm, covering the penile root circumference range of children and adolescents aged 3-18 years, ensuring comprehensive measurement. Its starting scale is adapted to the wall thickness of the main body of the measuring cylinder 1, so that the circumference value directly corresponds to the actual size of the penis and avoids errors.

[0027] Example 3

[0028] A gravity-driven method for measuring penis size includes the following steps: S1. Measurement Preparation: The upper and lower parts of the measuring cylinder 1 are assembled and fixed by a snap-fit ​​connection structure, ensuring that the slider 3 is in the initial position of the slide groove 2 and the flat cloth strip 8 is in the storage state.

S2.2 Raise the end of the measuring cylinder 1 so that the slider 3 slides naturally downward along the slide groove 2 under its own weight and the action of the built-in counterweight; S2.3 After the front end of the slider 3 has fully contacted the head of the penis and stopped sliding, read the corresponding value on the scale line 4 on the outside of the groove 2 through the pointers 5 on both sides of the slider 3. This value is the length of the penis. S3. Measure penile circumference: S3.1 Adjust the base of the penis to the measurement area corresponding to the circumference measurement component; S3.2 Hold the flat cloth strip 8 at one end that extends out of the hole structure 9 and slowly pull the receiving cavity box 6 so that it slides along the preset channel, while at the same time driving the flat cloth strip 8 to slowly wrap around the base of the penis; S3.3 Continue pulling until the preset mark is exposed inside the receiving cavity 6. At this time, the flat cloth strip 8 completely wraps the base of the penis with uniform tightness under the action of the spring 7. Read the corresponding scale value on the flat cloth strip 8 through the hole structure 9. This value is the circumference of the base of the penis. S4. Measurement complete: Slide slider 3 resets, flat cloth strip 8 is retracted, and measuring cylinder 1 is disassembled through buckle connection structure for cleaning and disinfection.
