A catheter is a thin, flexible tube that is inserted into the body to drain fluids or deliver medications. Catheters are used for a variety of medical purposes, including:
- Urinating: A urinary catheter is inserted into the bladder to drain urine. This may be necessary for people who are unable to urinate on their own, such as those with spinal cord injuries or neurological disorders.
- Delivering medications: Catheters can be used to deliver medications directly into the bloodstream or other parts of the body. This can be a more effective way to deliver medications than taking them orally, especially if the medication is not well absorbed by the digestive system.
- Draining fluids: Catheters can be used to drain fluids from the body, such as blood, pus, or bile. This may be necessary to treat infections or other medical conditions.
Catheters are made from a variety of materials, including latex, silicone, and polyurethane. The type of catheter used will depend on the specific purpose for which it is being used.
