A hypodermic syringe has the ability to retain liquid and blood in it up to years after the last use and a great deal of caution should be taken to use a new syringe every time. The hypodermic needle also serves an important role in research environments where sterile conditions are required.
A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the ...
This connector attaches to another device: e.g. syringe, vacuum tube holder/hub, or extension tubing from an infusion pump or gravity-fed infusion/transfusion bag/bottle. Newer models include a slide and lock safety device slid over the needle after use, which helps prevent accidental needlestick injury and reuse of used needles, which can ...
The insulin syringe was the first syringe that is considered low dead space. It was initially created with low dead space for accurate measuring and mixing of fast and slow acting insulin, which had the added benefit of wasting as little of the expensive drug as possible.
accelerate the syringe forward, puncturing the injection site; actuate the piston of the syringe, injecting the drug; deploy a shield to cover the needle; Some injectors are triggered by simply pushing the nose ring against the injection site. In these designs, the protective cap is the primary safety.
A range of Vacutainer tubes containing blood. A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid.
Pipetting syringes are hand-held devices that combine the functions of volumetric (bulb) pipettes, graduated pipettes, and burettes. They are calibrated to ISO volumetric A grade standards. A glass or plastic pipette tube is used with a thumb-operated piston and PTFE seal which slides within the pipette in a positive displacement operation ...
Auto Disable (AD) syringes are designed as a single use syringe, with an internal mechanism blocking the barrel once depressed so it cannot be depressed again. The other type of syringe with a re-use prevention feature is the breaking plunger syringe. An internal mechanism cracks the syringe when the plunger is fully depressed to prevent ...
