Pressure transmission tube and pressure detecting method used for urodynamic analyzer

Abstract

The present invention discloses a pressure transmission tube and a pressure detecting method used for a urodynamic analyzer. The pressure transmission tube comprises a transmission tube P (211), an evacuation tube Q (212) and a pressure sensor, the transmission tube P ( 211) and the evacuation tube Q (212) are respectively connected with two ports of the pressure sensor and can be easily disassembled, wherein the transmission tube P (211) comprises a liquid separator (2), a two-way valve A (20) and a two-way valve B (21), and the evacuation tube Q (212) comprises a two-way valve C (22). The two-way valve A (20), two-way valve B (21) and two-way valve C (22) with opening and closing functions can quickly discharge air in the pipelines and improve inspection efficiency and accuracy. A diaphragm (30) in the liquid separator (2) does not affect transmission of pressure, at the same time also blocks mutual contamination of patients' body fluid and the pressure sensor, also blocks cross infection of different patients by the pipeline, and thus effectively controls infections in hospitals. The transmission tube P (211) can be replaced to reduce costs.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pressure transmission tube and a pressure detection method for a urodynamic analyzer. Background technique [0002] The urodynamic analyzer is based on the basic principles and methods of fluid mechanics and electrophysiology to detect the pressure, flow rate and bioelectric activity of the patient's lower urinary tract to form intuitive and readable information for clinicians to understand the storage and urination of the lower urinary tract. Pathobiological changes in dysfunctional diseases. The system controls the perfusion rate of the perfusion unit and the traction speed of the traction unit through the computer. The bladder pressure test unit, rectal pressure (abdominal pressure) test unit, urethral pressure test unit, urine flow rate test unit, and electromyography test Pressure, rectal pressure (abdominal pressure), urine flow rate, and myoelectric signals are ...

AI Technical Summary

Problems solved by technology

[0003] Because the pressure sensor of the urodynamic analyzer communicates with the patient through the pressure sensor and the pressure measuring tube, the patient’s body fluid communicates with the pressure sensor, which creates a risk of infection. Therefore, it can be solved by one pressure sensor for each patient, but the cost is high , the risk of infection can also be reduced by replacing part of the pipeline, but there is still a risk of infection
