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 ...
Syringes: Disposable gloves: prevention of transmission of diseases (as long as not cut or perforated) to or from the user Tourniquet: This is used to cause an artificial venous stasis by applying pressure through this rubber tube. This leads to engorgement of the veins, allowing them to be seen more easily. Used for intravenous injections and ...
A syringe pump for laboratory use. World Precision Instruments (WPI) SP120PZ. A syringe driver, also known as a syringe pump, is a small infusion pump, used to gradually administer small amounts of fluid (with or without medication) to a patient or for use in chemical and biomedical research. Some syringe drivers can both infuse and withdraw ...
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.
Safety needles [1] serve the same functions as safety syringes, but the protective mechanism is a part of the needle rather than the syringe. Legislation requiring safety syringes or equivalents has been introduced in many nations since needlestick injuries and re-use prevention became the focus of governments and safety bodies.
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.
Like a ground glass stopcock, the two parts of a gas syringe should preferably not be interchanged with another gas syringe of the same volume, unless told otherwise by the distributor. [3] Gas syringes come in various sizes from 500 ml to 0.25 ml and tend to be accurate to between 0.01 and 1 ml, depending on the size of the syringe. [4]
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 ...
