In the field of medicine, a catheter means a thin tube featuring medical grade materials. These devices serve a vast range of functions. Catheters are medical devices that doctors or nurses insert in the body of the patient for the treatment of diseases or for performing a surgical procedure. You can make modifications in the material. Also, you can make some adjustments in the way catheters got manufactured. Experts tailor catheters for gastrointestinal, neurovascular, cardiovascular, urological, and ophthalmic applications.
Experts insert the Catheters into the body cavity, vessel, or duct. What is their function? These help in the drainage, administering of gases or fluids, access through surgical instruments, etc. Also, this performs a vast range of other tasks as per the type of catheter. The procedure for inserting a catheter is called catheterization.
In most cases, a catheter is a flexible, thin tube that is the soft catheter. However, catheters are available in various levels of stiffness. The doctors or nurses choose one as per the application. A catheter that experts place inside the body, permanently or temporarily, is an “indwelling catheter” (a peripherally inserted central catheter). A permanently inserted catheter is a “permcath”.
The catheter in hemodialysis is a tunnelled catheter since experts set it under the skin. You will come across two types of tunnelled catheters. Those are cuffed or non-cuffed. The non-cuffed tunnelled catheters are a suitable option for emergency cases and short spans. However, the tunnelled cuffed catheters is a type that the NKF recommends for temporary use. You can use this for a longer span.
