The most common site of insertion is the antero-medial aspect of the upper, proximal tibia as this site lies just under the skin and is easily located. Other insertion sites include the anterior aspect of the femur , the superior iliac crest, proximal humerus , proximal tibia, distal tibia and the sternum (manubrium). [ 1 ]
The term injection encompasses intravenous (IV), intramuscular (IM), subcutaneous (SC) and intradermal (ID) administration. [ 35 ] Parenteral administration generally acts more rapidly than topical or enteral administration, with onset of action often occurring in 15–30 seconds for IV, 10–20 minutes for IM and 15–30 minutes for SC.

The injection site must be cleaned before administering the injection, and the injection is then administered in a fast, darting motion to decrease the discomfort to the individual. The volume to be injected in the muscle is usually limited to 2–5 milliliters, depending on injection site. A site with signs of infection or muscle atrophy ...
Intradermal injection (also intracutaneous or intradermic, abbreviated as ID) is a shallow or superficial injection of a substance into the dermis, which is located between the epidermis and the hypodermis.
V-Set: Multiple line IV injection site whereby several lines can be used at the same time for administering drugs to the patient.. In intravenous therapy a Y-Set, T-Set and V-Sets are Y-, T- and V-shaped three-way connector sets made of connecting plastic tubes used for delivering intravenous drugs into the body from multiple fluid sources.
Schematic diagram of the human eye showing. Subconjunctival injection is a type of periocular route of injection for ocular drug administration by administration of a medication either under the conjunctiva or underneath the conjunctiva lining the eyelid.
The isoelectric shift also allows for the subcutaneous injection of a clear solution. The glycine substitution prevents deamidation of the acid-sensitive asparagine at acidic pH. In the neutral subcutaneous space, higher-order aggregates form, resulting in a slow, peakless dissolution and absorption of insulin from the site of injection. [20]
Some injectors are triggered by simply pushing the nose ring against the injection site. In these designs, the protective cap is the primary safety. Other designs use a safety mechanism similar to nail guns : The injection is triggered by pushing the nose ring against the injection site and simultaneously, while applying pressure, pushing a ...
