The Structure Of A Blunt Needle

A blunt needle is almost identical to a pointed needle, the key difference being that the tip is not tilted (or pointed). There are two kinds of blunt needles:

Blunt filling needle, used as a filling needle or extraction needle. They can remove the medication from any sealed medical container and transfer its contents to the desired container.

Blunt filter needle, this is a filled needle with an additional filter attachment. The filter prevents any solid particles in the liquid solution, especially if it is mixed from powder form.

Stuffed needles are necessary because medications are not usually prepackaged in syringe form, except for insulin injections. It is still possible to extract medicine from the container with a pointed needle, but this method increases the risk for the needlestick handler. Blunt needles are a safer but still effective method of extracting and transferring liquid solutions from airtight containers.
