The hypodermic needle model (known as the hypodermic-syringe model, transmission-belt model, or magic bullet theory) is claimed to have been a model of communication in which media consumers were "uniformly controlled by their biologically based 'instincts' and that they react more or less uniformly to whatever 'stimuli' came along".
The model was originally rooted in 1930s behaviourism and was largely considered obsolete for a long time, but big data analytics-based mass customisation has led to a modern revival of the basic idea. After that, a shift which rediscovered the relationship between media and people occurred and led to establishment of uses and gratifications ...
The needle on a safety syringe can be detachable or permanently attached. On some models, a sheath is placed over the needle, whereas in others the needle retracts into the barrel. 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 ...
A dose-sparing syringe and needle being used to draw up a COVID-19 vaccine. A dose-sparing syringe is one which minimises the amount of liquid remaining in the barrel after the plunger has been depressed. These syringes feature a combined needle and syringe, and a protrusion on the face of the plunger to expel liquid from the needle hub.
Unlike the hypodermic needle model, which considers mass media effects to be direct, the two-step flow model stresses human agency. For example, in the field of science communication, Matthew Nisbet describes the use of opinion leaders as intermediaries between scientists and the public as a way to reach the public via trained individuals who ...
Needle exchange programs are an effective way of decreasing the risk associated with needlestick injuries. These programs remove contaminated syringes from the street, reducing the risk of inadvertent transmission of blood-borne infections to the surrounding community and to law enforcement.
A syringe being prepared for injection of medication. An injection (often and usually referred to as a "shot" in US English, a "jab" in UK English, or a "jag" in Scottish English and Scots) is the act of administering a liquid, especially a drug, into a person's body using a needle (usually a hypodermic needle) and a syringe.

A syringe is connected to the epidural needle and the epidural space is identified by a technique to assess loss of resistance. Epidural administration is a procedure which requires the person performing the insertion to be technically proficient in order to avoid complications. Proficiency may be trained using bananas or other fruits as a model.
