When lying in the test, lie flat on the detector. Do not move it randomly during the inspection. 2. Actively cooperate with physicians and care for instruments. Inspection process (1) Stamp test: use an unbroken joint hole stamp to stick to the penis at the overlap before going to bed. If you wake up in the morning and see a tear at the ticket hole, it means that there is a valid erection at night. Debonding along the overlap is meaningless. This method is convenient, simple, and primitive, but it cannot estimate the degree of erection and the number of night erections. (2) Penis circumference measuring ruler: connect a square buckle at one end of the band-shaped flexible ruler, fix the tape ruler to the penis with a tape before going to bed, and wear the ruler around the end of the penis from the buckle, which can flex and move without resistance. Then look at the scale to read the base number, and then observe the scale to take another reading in the morning. The difference between the two numbers is the increase of the circumference of the night erection. The normal person increases the range from 1.5 to 4.1 cm, and the impotence patient increases by more than 1.5 cm. For functional impotence, less than 1.5 cm may be organic impotence. (3) Penis test ring: Three colored plastic strips are arranged in parallel on the buckle, and the three strips can be broken at 2.94 (blue), 4.41 (red), and 5.88 (white) KN tension. If there is no break after a good night's sleep, it indicates that there is no effective erection at night. If only the first (blue) breaks, it means that the hardness is the smallest, and sexual intercourse can be performed, but the insertion is difficult, if the second (red) also breaks. , indicating that there is sufficient hardness to insert, and the last one (white) also ruptures, indicating good hardness, which can be used as a screening diagnosis. (4) Night erection meter: The night erection meter is usually composed of a probe, a main unit and a recorder. It can trace the whole process of the length and diameter of the penis overnight. The number of erections, the duration of each erection, the length, the diameter, and the time interval between two adjacent erections are obtained from the recorded curve. (5) Rigiscan: The hardness tester is an instrument that can measure the nighttime swelling of the penis and measure its hardness. It consists of a storage part and a small electronic computer. Avoid snoring, drinking and taking medicine (except for medicines that must be used) before the examination, and reduce the factors affecting sleep. Generally, it is measured continuously for 3 times. This method quantifies the time and hardness of penile erection. Not suitable for the crowd Inappropriate people: not yet known.
