Insulin is a hormone made up of proteins and is naturally produced by the body to convert the food we eat into energy, sometimes body might have insulin insufficiency or insulin deficiency leading to diabetes characterized with high blood glucose level. Therefore, Insulin syringes came into use if your body is unable to produce enough insulin or is lack of insulin. The type of insulin syringes you need depends on your condition or insulin dosage. As there are different types of insulin, there are also different ways of injecting it. Insulin needs to be injected subcutaneously, that is into a layer of fat between muscle and the skin. Insulin syringes are made in several sizes.
1. A needle: The needle is short and thin and protected with a cap
2. A barrel : the barrel is a thin long chamber which holds insulin
3. Plunger: It is a movable tube which helps barrel to fill in and deliver the insulin
The gauge (width) of insulin syringes tends to be slim because of the regularity at which injections of insulin are taken. A cap covers and protects the needle before it is used. The barrel is the long, thin chamber that holds the insulin. The barrel is marked with lines to measure the number of insulin units.
A short length of needle would be less than 8mm A longer length of needle would be over 10mm long. The needle is short and thin and covered with a fine layer of silicone to allow it to pass through the skin easily and lessen pain. The length of the needle is dependent on degree of penetration into the subcutaneous layer and also on the thickness of the subcutaneous layer. The medical health professional advices on the length of the needle which may be best for you.
It is a long, thin movable tube kind of a rod that fits tightly inside the barrel of the syringe. It easily slides up and down to either draw the insulin into the barrel or push the insulin out of the barrel through the needle. The plunger has a rubber seal at the lower end to prevent leakage. The rubber seal is matched with the line on the barrel to measure the correct amount of insulin.
The procedure for drawing up a dose of insulin using a syringe is as follows:
You are now ready to give an injection.
