Description

Intelligent training method and system for catheterization

Technical Field

The invention relates to a medical teaching training system, in particular to an urinary catheterization intelligent training method and system.

Background

Catheterization is the insertion of a urinary catheter into the bladder via the urethra to draw urine. Aims to relieve the urine retention, take uncontaminated urine samples for examination, measure residual urine, measure the cold and heat feeling, the volume and the pressure of the bladder, inject contrast agents or medicaments to help diagnosis or treatment and the like. The operator stands on the right side of the patient, wears sterile gloves, uses sterile water or benzalkonium bromide to sterilize perineum and urethral orifice, sticks sterile lubricating oil to the front end of the catheter, holds penis with the left hand (if the patient is a female, the operator separates the labia minora with the thumb and the index finger to expose the urethral orifice), inserts the ureter into the bladder until the catheter has urine flowing out. Catheterization is an operation with high use frequency and great operation difficulty in clinical work. Students have few opportunities to train clinically; the traditional dummy has incomplete training process and part of training modes which are not in accordance with the reality; the student operation process is not monitored and error feedback is avoided; the existing model has incomplete training steps, only has an intubation link, and lacks steps of preoperative communication preparation, explanation and evaluation and the like; the method for determining the position of the catheter in the operation is to directly observe the naked bladder structure and is not in accordance with the actual diagnosis method; the traditional model person is dead, and corresponding feedback can not be given to students according to different operations of the students; the teacher has to teach the skill teaching in a classroom, and the daily training is difficult to develop; the traditional way of training is only skilled practice and lacks the cultivation of clinical thinking.
