Abstract

The invention belongs to the technical field of urethral catheterization in departments of urological surgery in hospitals and discloses a special urethral catheterization device for the departments of urological surgery in the hospitals, a control method and a control system. The control system comprises a pressure detection module, a flow rate detection module, a component detection module, a master control module, a guide module, a liquid storage module, a sterilization module, an alarm module, a calculation module and a display module. By the component detection module, a plurality of components of urine are measured quantitatively by an excitation light source capable of radiating monochromatic light in various wavelengths, so that short measurement and analysis time is realized. By the calculation module, voltage is applied to an electrochemical sensor first to enable reaction between the electrochemical sensor and the urine; then, response current generated after reaction between the electrochemical sensor and the urine is obtained; finally, specific gravity of the urine is calculated according to the response current. By adoption of the detection method, urine collection, reaction and result output are realized completely, high precision is realized, required equipment is simple, and simplicity in operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of urinary catheterization in hospital urology, and in particular relates to a special catheterization device for hospital urology, a control method and a control system. Background technique [0002] Catheterization is the insertion of a catheter through the urethra into the bladder to drain urine. The purpose is to relieve urinary retention, take uncontaminated urine samples for examination, measure residual urine, measure bladder cold and heat sensation, volume, pressure, inject contrast medium or drugs to help diagnosis or treatment, etc. The operator stands on the right side of the patient, wears sterile gloves, disinfects the perineum and urethral orifice with sterile water or benzalkonium bromide, dips the front end of the catheter with sterile lubricating oil, and holds the penis with the left hand (for female patients, the operator The thumb and index finger of the left hand separate the labia mino...
