Abstract

The invention discloses a urinary catheterization system for urinary surgery. The urinary catheterization system comprises a negative pressure tank, a catheter is connected to the upper portion of the negative pressure tank, a non-return mechanism is arranged at the end, connected with the negative pressure tank, of the catheter, a liquid outlet is formed in the bottom of the negative pressure tank, a negative pressure cavity is formed in the negative pressure tank, a box is arranged on one side of the negative pressure tank, a negative pressure pipe is arranged at the position, close to the top, in the box, one side of the negative pressure pipe is communicated with the negative pressure tank, The other end of the negative pressure pipe extends to the outside of the box body, the negative pressure pipe is connected with a universal joint and is connected with a central negative pressure system through the universal joint, and a valve is arranged on the universal joint; the middle position of the negative pressure pipe is connected with a Y-shaped pipe, one connector of the Y-shaped pipe is connected with a ventilation box, the other connector of the Y-shaped pipe is connected with a barometer, and a negative pressure mechanism is arranged above the ventilation box. An urine volume monitoring system is arranged to be matched with a negative pressure mechanism, urine catheterization is automatically carried out, the urine monitoring accuracy is improved, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of urinary catheterization, in particular to a catheterization system used in urology. 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. [0003] The current catheterization device generally uses a common drainage bottle, which is passed into the bladder through a catheter or an indwelling tube, and the urine automatically flows into the catheter bag through a natural drainage method. Since the urine is diverted at all times, it is not convenient for the patient's movement and perception and control of urine volume. It is necessary to always pay attention to the fluid storage volume of...
