An IV cannula is a small plastic tube that the doctor inserts into your vein through which they administer medicines or fluids. This nifty little tube is a necessity for those in need of life-giving care that can only be provided within the walls of a hospital or clinic. It has few key factors that help in working of it. A look at the various parts of an IV cannula and what they do
An Iv cannula consists of 3 parts needle, catheter then hub. The sharp thing on the end of a cannula is called a needle. It is extremely fine and pointed so slips easily through the skin into a vein. This needle is then inserted into the catheter. This catheter stays in the vein once the needle is placed. This small tube goes into the vein and deliver your medication or fluid. The hub is the big plastic part that a catheter leads to. This is critical as this where the doctor applies IV cannula which carries medicine or fluid in a bag into your blood.
The components of IV cannula have their specific functions. The needle is what enables the doctor to find a vein. It is also very sharp, so it helps the doctor to get through your skin. When the needle is successfully snuggled in a vein, moving around with your movement and rocked slightly from side to side simply bring this tubing out of you sliding it out withdrawn right beside the tube which stays inside directly when only cut arbitrary.optional. The catheter allows the observation, infusion of either medicine or fluids to a vein. It stays in place until the physician administers more medication or fluids if necessary. The hub is the part of the screw cannula that attaches to a medicine or fluid containing bag and adds strength, helping keep everything together.
IV cannulas are of various sizes. They come in different sizes, some are big, and others are small. The doctor can choose the best size of what this person needed for. If the patients need larger flows of fluids or medications quickly then 14 to size 24-gauge IV cannula. The smallest will be suitable for them if only a small medicine or fluid needs to use. Another thing is, what about the gauge? It says what size your catheter is. Bigger gauge = fluid flow is faster useful on some situations The doctor takes all these things into account and choose the option that will work for a specific patient.
Different kinds of material can be used to make IV cannulas. They would be in plastic or metal. This procedure is more often done with flexing IV cannulas made of plastic, which are stiffer rather than a softer and sprung metal. They are also hypoallergenic, which means they are good for more people. Metal IV Catheters on the other hand are so much better and should practically always be Used where needle gauges allow for it. They are suggested for blood transfusions as well, because they can resist against the flow of bloof with lesser toxicity.
