Disposable Insulin Syringe 1ml 0.3ml 0.5ml Ce&ISO

An insulin syringe has three parts: a needle, a barrel and a plunger.

The needle is short and thin. It is made of a special material that allows the needle to slide through the skin easily with less pain. It comes with a cap to cover and protect it before it is used.

The barrel is the plastic chamber that holds the insulin. It is marked with lines (calibrations) on the side. The lines show you how many units of insulin you are injecting.

The plunger is the long thin rod that slides up and down the inside of the barrel. Its function is to either draw the insulin into the barrel or push the insulin out of the barrel through the needle. It has a rubber seal at the lower end to prevent insulin from leaking out. The rubber seal is fitted in such a way that it matches the line on the barrel.

Syringes are meant for one-time use. Once used, they must be thrown away in special puncture-proof containers.

The larger the syringe size, the more insulin it can hold.

When choosing the size of a syringe, consider:

1)the number of units of insulin you need, and

2)how well you can see the line markings on the barrel.

 How to Read a Syringe

When measuring the amount of insulin, read from the top ring (needle side), and not the bottom ring or the raised section in the middle of the plunger.

For example, Figure 1 shows a 100 unit insulin syringe. Each line represents two units of insulin. Therefore the syringe contains 32 units of insulin. As the lines are very close together, this is not the syringe of choice for a person with poor vision.
