Kanüülide

Kanüülide refers to cannulas, which are medical devices that are typically hollow and cylindrical. They are used in a variety of medical procedures to introduce fluids into the body or to drain fluids from it. Cannulas can be made from different materials, including plastic, metal, and rubber. The specific design and size of a cannula depend on its intended use.

One common application of cannulas is in intravenous (IV) therapy. An IV cannula is inserted into a vein to allow for the administration of medications, fluids, and blood products. These cannulas are usually made of plastic and come in various gauges, with smaller gauges being thinner and larger gauges being thicker. Another use is in surgical procedures, such as laparoscopy, where a cannula is inserted through a small incision to create a port for surgical instruments.

Cannulas are also employed in respiratory care. For instance, nasal cannulas are used to deliver supplemental oxygen to patients with breathing difficulties. These are flexible tubes with prongs that rest in the nostrils. Additionally, suction cannulas are used to remove secretions from the airway. In ophthalmology, cannulas can be used in procedures to deliver medication or to drain fluid from the eye. The sterile nature and precise dimensions of cannulas are crucial for patient safety and the success of medical interventions.
