Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 Shown is the urine line F-value ruler described in the method of the present invention. The urine line F-value ruler is composed of several columns with different thicknesses. The columns of different thicknesses represent different urine line F-values, including 3F, 4F, 5F, 6F, 8F, 10F, 12F, 14F, 16F and 18F, wherein, F is the circumference length of the section of the column in mm.

[0025] Utilize the method of the present invention to measure the state of urine line F value such as figure 2 As shown, the human body urinates to form a urine line 1, and a urine line F-value ruler 3 is set at an interval of 3 cm beside the urine line 1, and a digital camera 2 is set at the same time to dynamically capture the urine line 1 and the urine line F-value ruler formed in the process of human urination 3.

Abstract

The invention belongs to the technical field of micturition dynamics and relates to a method for determining a urinary stream F value. The method comprises the steps of dynamically capturing a urine stream of a human body during micturition, dynamically recording urine stream data in the whole micturition process, and simultaneously placing a urine stream F value reference substance beside the urine stream of the human body during micturition; then obtaining the F value corresponding to the urine stream in the urine stream F value reference substance when the human body urinates by comparing the urine stream when the human body urinates with the urine stream F value reference substance; and finally calculating and acquiring the urine stream F value when the human body urinates. The urine stream F value is obtained in a direct determination way, and the technical problem in the prior art is solved that the urine stream F value cannot be directly determined.

Description

technical field [0001] The invention belongs to the technical field of urination urodynamics, and relates to a method for measuring the F value of a urine line. Background technique [0002] Urethral F-score refers to the F-score at which the urethra is dilated by the urine flow during urination, and is usually displayed by excretory urethrography. Urethral F value = 10dπ = 20rπ, the urethral F value of each urethral segment is different. The actual unit of F value is expressed in millimeters and mm for the circumference of the section of the urethral cavity during urination, while the unit number of the section diameter d and radius r of the urethral cavity during urination is cm. Then, the formula for the unified unit is: F value = 10dπ = 20rπ. During urination, the posterior urethra and membrane can actively relax and passively bear the brunt of expanding the urethral cavity, which truly reflects the F value of the posterior urethral cavity. The rest of the anterior ur...
