A Foley catheter is a flexible tube designed to be inserted into the bladder to drain urine. It is commonly used for patients who are unable to urinate on their own due to surgery, certain medical conditions, or immobility.
Features:
1. Material and Coating:
-
Latex Construction: Durable and flexible, providing comfort and ease during application.
-
Silicone Coating: Reduces irritation to the urethra, is resistant to chemicals, and is insensitive to temperature changes, making it safer and more comfortable for long-term use.
2. Design:
-
2-Way Design: Contains two separate channels (lumens):
-
One for urine drainage (open-ended lumen).
-
One for inflating the balloon at the tip (balloon keeps catheter in place inside the bladder).
-
Straight Tip: Helps with straightforward and gentle insertion.
-
Color-coded: The catheter tube is marked with colors for easy size identification (e.g., white for 12Fr).
-
Large Oval Drainage Eyes: Allow maximum urine drainage.
-
Balloon: A symmetrical 5 cc balloon inflates at the bladder neck with sterile water to secure the catheter.
3. Sizes Available:
-
French (Fr) Sizes: 12, 14, 16, 18, 20, 22, 24 Fr – the number indicates the diameter of the catheter (most adult catheters range from 14 Fr to 18 Fr).
4. Sterility and Safety:
-
Individually Sterile Wrapped: For single use to prevent infection.
-
DEHP-free and BPA-free: Avoids certain plasticizers for improved patient safety.
-
Contains Natural Rubber Latex: Always check for latex allergy before use.
How Does It Work?
-
Insertion: The catheter is gently inserted through the urethra into the bladder.
-
Balloon Inflation: Once in place, the balloon at the tip is inflated with 5 cc of sterile water, preventing the catheter from slipping out.
-
Urine Drainage: Urine flows from the bladder, through the catheter, into a collection bag.
-
Removal: Before removing, the balloon is deflated.
Common Uses:
- Post-surgery urinary drainage
- Management of urinary retention or incontinence
- Comfort for bedridden or immobile patients
Note: This Foley catheter contains latex, so it should not be used in patients with a latex allergy.
About the 5 cc Balloon
-
Function: The balloon, located near the catheter’s tip, is inflated after insertion into the bladder. It holds the catheter securely in place, preventing it from slipping out.
-
Capacity: A 5 cc balloon is inflated using 5 mL of sterile water via a dedicated channel (lumen). (Some clinicians use 10 cc fluid in a 5 cc balloon, but this is not generally recommended unless specified by the manufacturer.)
-
Common Use: The 5 cc balloon is standard for adult Foley catheters and suits most general urinary drainage indicating situations.
When is the 5 cc Balloon Foley Catheter Used?
-
Short- to medium-term drainage (post-op, urinary retention, monitoring urine output)
-
Not typically for long-term or special patient groups (e.g., long-term may use larger balloons for stability)
Types & Sizes
-
Sizes: Catheter diameter is measured in “French” (Fr), generally ranging from 12 Fr to 24 Fr for adults.
-
Material: Silicone, latex, silicone-coated latex, hydrogel-coated, etc.
-
Sterility: Individually packed for single use.
Common Design Features
-
Straight, rounded tip for ease of insertion.
-
Two lumens: 1 for urine drainage, 1 for balloon inflation.
-
Multiple Eye-holes (Drainage Ports): Allow urine outflow from the bladder.
-
Balloon Capacity Marked Clearly on the inflation port, e.g., “5 cc ONLY.”
-
Color-Coding: To indicate size for quick identification.
Advantages of the 5 cc Balloon Size
-
Reduced bladder irritation compared to larger balloons.
- Less risk of post-removal hematuria or trauma.
- Preferred for general adult use.
Cautions and Tips
- Never use more solution than indicated (usually 5-10 mL for a 5 cc balloon) as over-inflation may rupture the balloon or cause bladder trauma.
- Use sterile water ONLY—not saline.
- Always check for latex allergies if using a latex or latex-coated catheter.
- Balloon capacity and catheter size must match clinical indication (consult hospital protocol or manufacturer’s instructions).
Quick FAQ
-
Q: Why not use a 30 cc balloon as standard? A: Larger balloons (30 cc) are mostly reserved for special indications (e.g., after prostate surgery for hemostasis). For most adult patients, a 5 cc balloon is less traumatic and provides adequate retention.
-
Q: What happens if you don't deflate the balloon before removal? A: Attempting to remove a catheter with an inflated balloon can cause significant pain, urethral injury, or bleeding.
