Urethral canal pressure measuring pipe, pressure measuring device and fluid form resistance measuring device

Abstract

The invention provides a urethral canal pressure measuring pipe, a pressure measuring device and a fluid form resistance measuring device. The pressure measuring pipe comprises a filling cavity, threepressure measuring cavities and four channels arranged integrally, and open holes corresponding to corresponding positions of a human body. In four channel ports of the first end of the pressure measuring pipe, a filling cavity channel port is used for connecting with a filling pump, and three pressure measuring cavity channel ports are used for connecting with a pressure sensor respectively; after the pressure measuring pipe stretches into a preset position of a urethral canal of the human body, the open hole of the filling cavity is located on the most tail end of the pressure measuring pipe and is located in a bladder of the human body; the open holes of the three pressure measuring cavities are respectively located in the bladder of the human body, the lower end of prostate and a position which is 2+ / -0.5cm far away from an in-vitro urethral canal outlet of the human body; each urethral canal fluid form resistance is calculated according to a formula as shown in the description, so that a urethral canal obstruction type and a prostate obstruction degree can be conveniently evaluated.

Description

technical field [0001] The invention relates to a urethral pressure measuring tube, a pressure measuring device and a fluid form resistance measuring device, and relates to the field of medical instruments. Background technique [0002] Lower urinary tract symptoms (Lower Urinary Tract Symptoms, LUTS) are common in men. Among men over 50 years old, one-third of the population has lower urinary tract symptoms, and its incidence and severity increase with age. Among the lower urinary tract symptoms in men, symptoms during urination are the most common, such as urinary hesitancy, intermittent urination, strenuous urination, dribbling, and incomplete urination. Voiding symptoms usually indicate urethral obstruction. After the formation of urethral obstruction, in order to overcome the voiding resistance, the contractility of bladder detrusor muscle increases, smooth muscle fiber hyperplasia, easy to form pseudo bladder diverticulum; during the process of bladder detrusor compens...

Problems solved by technology

However, these analysis methods can only judge whether there is obstruction based on empirical data, but cannot distinguish the type of obstruction (prostate, urethral stricture, etc.); Bladder capacity, physiological state, etc.) to make statistics on the absolute physical data measured as a general judgment standard, resulting in a lack of consistency and authenticity in the judgment results
