Why tap syringe

Hard plastic or metal container with a screw-on or tightly-secured lid Parts of a Syringe and Needle You will use a syringe and needle to give the shot. The parts are labeled below. Drawing up the drug into the syringe Wash the work area where you will set the drug and syringe well with soap and water.

Wash your hands. Check the drug label to be sure it is what your doctor prescribed. Check the expiration date on the vial. Do not use a drug if: It is past the expiration date You see small pieces floating in it It is discolored Call your pharmacist if this happens. Remove the lid from the top of the drug vial. Wipe the rubber top with an alcohol swab or a cotton ball moistened with alcohol.

Check to make sure the needle is attached tightly to the syringe. Turn it clockwise to the right to tighten it. Remove the plastic needle cap by pulling it straight off.

Do not touch the needle. If the needle touches any surface, it will need to be replaced before you use it. Pull back the plunger of the syringe to your prescribed dosage. This will draw air into the syringe. Place the drug vial on a flat surface, and push the needle through the rubber top. Push down on the plunger to push air into the vial.

Turn the vial upside down, holding the syringe and needle in place. Make sure the tip of the needle is in the drug solution. Then pull the plunger back by the flat knob. This will draw the drug into the syringe. Keep pulling on the knob until the drug reaches the prescribed dosage. Check for air bubbles in the syringe. Just before getting shots - if you're not too busy cringing or escaping to a happy place in your mind - you'll notice that I, and other doctors, turn the needle upside down then curiously flick it with our index fingers once or twice followed by a small squirt of the medicine or vaccine release from the tip of the needle.

Why do doctors and nurses perform this ritual? Make sure you have the right medicine. Check the date on the vial. Do not use medicine that is out of date. You may have a multi-dose vial. Or you may have a vial with powder that you mix with liquid.

Read or ask about instructions if you have to mix your medicine. If you will use the medicine more than once, write the date on the vial so you remember when you opened it. Look at the medicine in the vial. Check for a change in color, small pieces floating in the liquid, cloudiness, or any other changes.

Get the Vial Ready Prepare your medicine vial: If this is your first time using this medicine, take the cap off the vial. Wipe the rubber top clean with an alcohol pad.

Filling the Syringe With Medicine Follow these steps to fill the syringe with medicine: Hold the syringe in your hand like a pencil, with the needle pointed up.

Insert the needle into the rubber top. Push the air into the vial. This is a public Site and all posts on this Site can be seen by anyone and may be shared freely with others.
