Product Description:

A medical catheter is a medical device used to guide urine out of the patient’s bladder. Here is some basic information about medical catheters:

1. Design and structure: Medical catheters are usually made of soft plastic or silicone materials, which are soft and elastic enough to pass through the urethra and enter the bladder. Their design usually includes a slender tubular structure with one end connected to a urine collection bag or drainage system and an opening or balloon at the other end for fixation in the bladder.

2. Uses and functions: Medical catheters are mainly used in the following aspects:

3. Temporary drainage: After surgery or certain disease states, it is necessary to temporarily guide urine out of the bladder to reduce pressure in the bladder and promote recovery.

4. Monitoring urine volume and properties: In intensive care, operating rooms or other clinical environments, catheters can be used to monitor the patient’s urine volume and urine properties to help medical staff assess the patient’s health status.

5. How to use: When performing catheterization, medical staff first fill the balloon of the catheter with liquid and insert it into the patient’s urethra until the balloon is completely inserted into the bladder. Then, through the fixation of the balloon, the catheter is safely fixed in the bladder to drain urine into a connected urine collection bag or other drainage system.

6. Advantages and limitations: The advantages of medical catheters include:

7. Relieve bladder pressure: When the bladder cannot urinate normally, the catheter can effectively reduce the pressure in the bladder and prevent urine retention.

8. Monitor urine volume: The patient’s urine volume can be accurately measured to help assess fluid balance and kidney function.

9. Easy to manage: After surgery or when long-term urine drainage is required, the use of a catheter can reduce frequent urine collection operations.

Although the catheter plays an important role in medical practice, it also has some limitations, such as the risk of urinary tract infection and the possibility of urethral damage due to long-term use. Therefore, medical staff usually pay attention to hygiene and timing when using the catheter to minimize these risks.
