Accurate negative pressure control-based plasticity penis measuring instrument and measuring method

Abstract

The invention discloses an accurate negative pressure control-based plasticity penis measuring instrument and a measuring method. The measuring instrument comprises a flexible detection chamber, a sliding rail, a detection ring, an observation port, a fastening airbag, an air pipe, a fixing mechanism and a negative-pressure air suction inflation instrument, wherein the detection ring is arranged on the sliding rail, and is glidingly connected with the sliding rail; the observation port is arranged on the sliding rail; the sliding rail is cared with scales; the fastening airbag is installed onthe flexible detection chamber; the fastening airbag communicates with the negative-pressure air suction inflation instrument through the air pipe; and the flexible detection chamber communicates withthe negative-pressure air suction inflation instrument. According to the measuring instrument, a penis is drawn through negative pressure, and negative pressure suction force is controllable, so thatthe situation that a person under measurement touches the penis with hands to result in that the penis erects due to stimulation is avoided; since the negative pressure suction force is controllable,the person under measurement can be protected from pain or inconvenience; and meanwhile, through individualized accurate negative-pressure drawing, the length of the penis under a drawn state is accurately obtained.

Description

technical field [0001] The invention relates to an auxiliary device for judging abnormal sexual development of children and adolescents, in particular to a plastic penis measuring device based on precise negative pressure regulation, which belongs to the field of medical devices. Background technique [0002] From a historical and cultural point of view, penis length is a very important concern for both men and women, and it is an important symbol of male masculinity; from the perspective of plastic surgery, the normal range of penis length is a urologist. An important reference for penile lengthening plastic surgery; from the perspective of growth and development, penis growth is mainly regulated by the endocrine level of the hypothalamus-pituitary-gonad axis, and penis length is an important indicator for evaluating the sexual development of male children and adolescents. To judge whether a child's sexual development is normal, the penis length must be accurately measured ...

AI Technical Summary

Problems solved by technology

[0008] (1) Vernier caliper measurement: the tip is sharper, and infants and children are prone to damage if they do not cooperate.

[0009] (2) Hard ruler measurement: When measuring, it is necessary to use a ruler to press or push away the prepubic fat pad to the greatest extent, which may easily cause children to avoid pain, and the ruler cannot be close to the pubic bone, resulting in measurement errors, especially for obese children. still obvious

[0010] (3) Ultrasonic wide-view imaging measurement: high requirements for operators, professional training is required

However, this method cannot accurately control the negative pressure artificially applied to the detection site, so as to cause excessive or insufficient negative pressure suction, thereby affecting the accuracy of detection data

[0012] (5) The rulers and vernier calipers currently mainly used in China are reusable, and the measuring tools under ideal conditions should have the characteristics of one-time use and sterilizing agents on the surface.

[0014] (1) The existing technical means cannot quantify the minimum draft pressure adjustment unit during the draft test, and the excessive draft pressure adjustment gap cannot quantify the pain of the subject, which will cause discomfort or fear to the subject

[0015] (2) Existing technical means cannot accurately control the negative pressure suction that is artificially applied to the detection site, resulting in excessive or insufficient conditions, further affecting the accuracy of the detection data

[0016] (3) There is no relatively uniform testing standard in various places, it is difficult to implement correct big data collection and analysis, and the research and application of relevant data develop slowly

[0017] It should also be pointed out that when using existing tools and techniques to measure penis length, even if the measurements are taken by the same person, different levels of children's cooperation, prepuce or phimosis that prevent the apex of the glans from being exposed will lead to variability in the measurement results bigger

In addition, because the "damping coefficient" of the penis before puberty, during puberty and after puberty is different when it is stretched, it is obviously not accurate enough to measure the same negative pressure traction for penises with different "damping coefficients".

In addition, the above-mentioned measurement tools require the examiner to pull the penis by hand. For older teenagers, there are obvious tendencies of shyness, avoidance, and resistance when measuring the penis manually.

On the other hand, when the examiner's hand touches the examinee's penis, it is easy to cause the examinee's penis to become erect, resulting in a large variation in the measurement results
