An autoinjector (or auto-injector) is a medical device for injection of a premeasured dose of a particular drug. Most autoinjectors are one-use, disposable , spring -loaded syringes ( prefilled syringes ).
A Bosch mechanical direct-injection system was also used in the straight-eight used in the 1954 Mercedes-Benz W196 Formula One racing car. The first four-stroke direct-injection petrol engine for a passenger car was released the following year, in the Mercedes-Benz 300SL sports car. [38]
Vastus lateralis site for intramuscular injection ALK Pharma Jext300, adrenaline autoinjector, without its safety cover. Epinephrine autoinjectors are hand-held devices carried by those who have severe allergies; the epinephrine delivered by the device is an emergency treatment for anaphylaxis.
By design, autoinjectors are easy to use and are intended for self-administration by patients. The site of injection depends on the drug loaded, but it typically is administered into the thigh or the buttocks. The injectors were initially designed to overcome the hesitation associated with self-administration of the needle-based drug delivery ...
In a naturally aspirated engine, air for combustion (Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre ...
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).
Adams was the first to die by lethal injection in South Carolina. Robert South, 51, executed on May 31, 1996, killed West Columbia police Officer Daniel Cogburn in a drive by shooting in 1983 ...
A newer model, the ATNAA (Antidote Treatment Nerve Agent Auto-Injector), [1] has both the atropine and the pralidoxime in one syringe, allowing for simplified administration. The use of a Mark 1 or ATNAA kit inhibits the nerve agents' purpose, thereby reducing the number of fatal casualties in the advent of chemical warfare.
