Embodiment Construction

[0020] In order to clearly illustrate the technical solutions in the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] 1. Horizontal box platform (A)

[0022] The box part of the horizontal box platform is mainly used as a storage space for measuring components such as flexible water pipes, telescopic rods and weights. A column (A-6) is designed at the bottom of the box, and the flexible water pipe (C) is wound on the column to prevent the winding of the flexible water pipe and the deformation of the pipeline. There are 3 box feet at the bottom of the box, among which, the height of the box feet (A-3) is fixed, and the box feet (A-1, A-2) are adjustable screw structures with adjustable heights, which are used to adjust the level of the box platform. The upper cover of the box body is a detachable movable plate (A-4), which is fixed on the box body with quick-connect screws when ...

Abstract

The invention discloses a portable standard water pressure device, which is used for calibrating a urodynamic analyzer. The portable standard water pressure device comprises a horizontal box body platform (A), a detachable telescopic rod (B), a water level identifying cylinder (E) and a vertical indicator (H) used for carrying out vertical detection on the detachable telescopic rod (B), wherein the horizontal box body platform (A) is provided with a device for performing horizontal adjustment on the horizontal box body platform (A); a stand column (A-6) is fixed inside a box body of the horizontal box body platform (A), and the stand column (A-6) is wound with a flexible water pipe (C); each section of a pull rod of the detachable telescopic rod (B) is provided with height scales; the lower end of the flexible water pipe (C) is communicated with a pressure measuring channel of the urodynamic analyzer, and the upper end is connected with the water level identifying cylinder (E); and the water level identifying cylinder (E) is fixed on one section of the pull rod through a movable clamp (G). The portable standard water pressure device can effectively solve the daily calibration problem of pressure parameters of the urodynamic analyzer.

Description

technical field [0001] The invention relates to the field of clinical detection of medical equipment, in particular to a portable standard hydraulic device. Background technique [0002] Urodynamic analyzer is an instrument used to analyze the function and mechanism of urination in the lower urinary tract, as well as the pathological and physiological changes of urinary dysfunction diseases. It is generally integrated with three-way extrusion pressure sensors to measure bladder pressure, abdominal pressure, and urethral pressure. , since the non-negligible zero drift of the extrusion pressure sensor and the aging of the rubber membrane will significantly affect the accuracy of the pressure measurement of the urodynamic analyzer, it is necessary to perform daily calibration of the pressure parameters of the urodynamic analyzer. The reference zero point of the pressure measurement of the urodynamic analyzer is different from the usual pressure measuring instrument. It does not...
