What is a syringe plunger?
The plunger, or piston, is the component of the prefilled syringe that, when depressed, pushes the vaccine-containing liquid out through the needle into the patient. The stopper at the end of the plunger must move smoothly in the barrel while preventing any leakage or possible contamination.
How do you use a plunger syringe?
To operate a syringe, first make sure the plunger is pressed down to the bottom of the barrel. Then, place the tip in the liquid that you want to measure. Draw back on the plunger and the liquid will flow into the syringe, as demonstrated in the image above.
Does a syringe have a plunger?
Syringes smaller than 1 mL have a stainless steel plunger for syringes, as shown in the picture on the left.
What is a syringe used for?
Syringes – devices used to inject medication into or withdraw fluid from the body. Lancets, also called “fingerstick” devices – instruments with a short, two-edged blade used to get drops of blood for testing.
Can you touch the plunger of a syringe?
Do not touch or bend the needle. Depress the plunger and push the air into the vial. This keeps a vacuum from forming so that the medicine will flow easily into the syringe.
What is syringe pumps?
Syringe pumps, or syringe drivers, are motorised devices that accurately control the movement of a fluid from a syringe by mechanically inserting or retracting the plunger. Syringe pumps feature stepper motors which can accurately move a platform attached to the plunger of a syringe.
What is needle in syringe?
A hypodermic (hypo – under, dermic – the skin) needle is a hollow needle commonly used with a syringe to inject substances into the body or extract fluids from it.
What is syringe injection?
Hypodermic syringes are used with hypodermic needles to inject liquid or gases into body tissues, or to remove from the body.
What is syringes and needles?
BD® is a leading manufacturer and provider of safety injection needles and syringes1,2, continually pioneering the development of high-quality, easy-to-use injection devices designed to protect healthcare workers from needlestick injuries and exposure to bloodborne pathogens.
Why do we use syringe pump?

Where are syringe pumps used?
An infusion pump is a medical device that delivers fluids, such as nutrients and medications, into a patient’s body in controlled amounts. Infusion pumps are in widespread use in clinical settings such as hospitals, nursing homes, and in the home.
What is a plunger used for in a syringe?
This plunger is used for syringes 500 µL and smaller intended for use in an automated syringe pump. A special plunger button protects the delicate plunger wire by stopping the pump at the zero line before damaging the tip. The stop also provides a 6-32 threaded hole that is used to mount the plunger into the syringe drive.
What is a syringe?

What size plunger do I need for a 7000 syringe?
This plunger is exclusively for 0.5 – 5 µL volume 7000 series syringes. The end of the plunger has a tungsten wire extension that fits the entire length of the needle all the way to the tip, resulting in zero dead volume. This 7000 series syringe is used for dispensing minute liquid volumes.
What is a back bushing on a syringe?
This plunger is for full-height syringes with a 60 mm stroke length. This plunger features a stop and a back bushing. The back bushing increases the plunger tip life, maintains proper plunger alignment and reduces the particles generated by plunger and glass contact.
