A Foley catheter, also known as an indwelling catheter, is a medical device used for urinary drainage. The term "2-way" refers to the type of Foley catheter that has two lumens or channels. Here's a brief description:
-
Purpose:
- The primary purpose of a Foley catheter is to drain urine from the bladder when natural voiding is not possible or advisable. It is often used in medical settings, post-surgery, or for individuals with certain medical conditions.
-
Construction:
- A Foley catheter consists of a flexible tube made of medical-grade materials, such as latex or silicone. It is typically equipped with an inflatable balloon near the tip and has two separate lumens or channels.
-
Two-Way Design:
- The "2-way" designation indicates that the Foley catheter has two lumens. One lumen is for urine drainage, and the other lumen is connected to a balloon near the tip. This balloon is inflated with sterile water once the catheter is inserted into the bladder, anchoring it in place.
-
Inflation and Deflation:
- The balloon allows the catheter to remain securely in the bladder. It can be inflated and deflated as needed for insertion, removal, or repositioning. Healthcare professionals use a syringe to add or remove sterile water from the balloon.
-
Drainage:
- The drainage lumen has multiple openings near the tip inside the bladder, allowing urine to flow into the catheter and then into a drainage bag for collection.
-
Materials:
- Foley catheters can be made of latex or silicone. Some individuals may have latex allergies, and in such cases, a silicone Foley catheter is often preferred.
-
Sizes:
- Foley catheters come in various sizes or French sizes, referring to the diameter of the catheter. The appropriate size is chosen based on the patient's anatomy and medical requirements.
-
Placement:
- A healthcare professional typically inserts the Foley catheter into the bladder through the urethra. In some cases, it may be inserted through a suprapubic incision, particularly if there are issues with the urethra.
-
Maintenance:
- Regular care and hygiene are essential for individuals with Foley catheters to prevent urinary tract infections. The drainage bag is emptied and cleaned regularly, and the catheter site is inspected for signs of infection.
-
Indications:
- Foley catheters are commonly used in various clinical situations, including post-surgical recovery, management of urinary retention, monitoring urine output in critically ill patients, and palliative care.
It's important for healthcare professionals to carefully manage and monitor individuals with Foley catheters to prevent complications and ensure proper functioning. The use of Foley catheters should align with medical guidelines and the patient's specific needs.
