Catheterization is a common procedure during medical procedures, especially when urine volume needs to be monitored, the bladder needs to be emptied, or preparation for surgery is required. The success of urinary catheterization largely depends on the correct selection and operation of the catheter. So, in the face of catheterization models, do you really know how to correctly select and operate a catheter?

First of all, we need to clarify the principle of catheter selection. The catheter size should be appropriate, too thick or too thin can cause discomfort or urethral damage to the patient. In the selection, we need to consider the patient's age, gender, disease and other factors, as well as the length and diameter of the urethra. In addition, pay attention to the material of the catheter, generally speaking, the silicone catheter is soft and biocompatible, more suitable for long-term use.

After selecting the catheter, we need to master the correct method of operation. When operating on a catheterization model, it is first necessary to ensure that the operating environment is sterile and clean to prevent urinary tract infections. The urethra is then cleaned and disinfected with disinfectant in accordance with the principles of aseptic technical operation. Next, we can simulate the operation with the help of the catheterization model. During operation, note the following points:

When inserting a catheter, keep the catheter clean and sterile to avoid contamination.

Insertion should be gentle and slow to avoid damage to the urethra. For male patients, due to the length of the urethra and the presence of curvature and stenosis, special care should be taken when inserting.

Insertion depth should be moderate, too shallow may not be able to extract urine, too deep may damage the bladder wall. When operating on a catheterization model, the insertion depth can be determined based on the structure and markings of the model.

In the process of catheterization, it is necessary to always pay attention to the patient's response and urine volume changes, and timely adjust the operation method and speed.

Through repeated simulation operations on the catheterization model, we can master the selection and operation of the catheter, and lay a solid foundation for future clinical practice. At the same time, it is also necessary to pay attention to continuous learning and summing up experience and lessons in practice to continuously improve their professional skills and service quality.
