Comfort and Biocompatibility: Why Choose an All Silicone Foley Catheter

2025-09-18

Product Overview

The All Silicone Foley Catheter is a sterile, single-use medical device widely used for urinary drainage in clinical settings. Made entirely of medical-grade silicone, it offers excellent biocompatibility and reduces irritation or trauma to the urethral mucosa during use.


Structure and Components

The catheter consists of the following main parts:


  • Drainage Lumen


Location within the catheter shaft, this lumen is responsible for draining urine from the bladder.


  • Inflation Channel


Connected to the balloon, this channel is used to inflate or deflate the balloon after the catheter is inserted.


  • Balloon


Situated near the distal tip, the balloon is inflated once inside the bladder to hold the catheter securely in place and prevent accidental dislodgement


  • Funnel Connector and Inflation Valve


Found at the proximal end of the catheter, the funnel allows connection to a urine drainage bag, and the inflation valve is used for injecting fluid into the balloon.


  • Labeling


The balloon capacity (e.g., 5mL, 10mL, 30mL) is clearly marked on both the funnel and the catheter body for easy identification during clinical use.


Material Comparison

Foley catheters are commonly made from either latex or silicone, each material having its own advantages and disadvantages:

Latex Catheters

Advantages: Excellent flexibility, high cost-effectiveness, and wide applicability.

Disadvantages: Latex proteins may trigger allergic reactions in some patients, especially with long-term use.


Silicone Catheters

Advantages: High biocompatibility, minimal risk of allergic reactions, smooth surface that resists encrustation, and suitable for long-term indwelling use (up to 4 weeks or more).

Disadvantages: Firmer texture compared to latex, and generally higher cost.


Clinical Applications and Precautions

All Silicone Foley Catheters are particularly suitable for patients who require long-term catheterization, such as post-operative case, chronic urinary retention, or those in intensive care.

The following precautions should be observed during use:


  • Maintain sterile technique during insertion to prevent urinary tract infection.
  • Inflate the balloon with the correct amount of sterile distilled water as indicate on the label (do not use saline, which can crystallize and block the valve).
  • Regularly monitor catheter patency, urine volume, and urine characteristics.
  • Replace the catheter or seek medical attention if discomfort, hematuria, or drainage obstruction occurs.
