An autoinjector is a medical apparatus that plays the role of delivering a dose of a specific drug. Initially, interjectors were created for the sole purpose of replacing the needle-based delivery services since self-administration had some hesitations that came with it.

Many pharmaceutical companies offer a autoinjector training device globally to provide market insights. Most autoinjectors have disposable spring syringes which can be used once. Autoinjectors are designed in a simple way to enable patients self-administer the drugs easily by themselves. The injection is administered into the buttocks or thighs though the drug-loaded determines the site of the injection.

There are numerous designs created for both subcutaneous and intramuscular injection. The disposable autoinjectors use a Pre-loaded spring as a power source. A single shot of the linear actuator is formed by the mechanical components associated with this spring and the spring itself.

The actuator gets into a three-step sequence when triggered.

  1. a) Punctures the injection side after thrusting the syringe forward
  2. B) Injects the position of the drug after actuating the syringe’s piston
  3. c) Covers the needle through the shield it deploys

Minor actions like thrusting the ring onto the injection site often trigger some injectors. The foremost safety is the protective cap when it comes to these designs. Safety channels that operate like nail guns have been incorporated in other designs. Pressure is applied when you trigger the injection, thus thrusting the trigger button at the end of the device.

There are various health risks posed on waste management employees because spent autoinjectors have a hypodermic needle. Hence, the hand is kept sterile, and adequate wastes are confined after disposal because the protective cap is designed.

The depth of an adjustable injection contains layers of clothing for injectors that carry out the application. Additional features include; an audible click after the infusion, a color-coded spent indicator, and a drug inspection window.


Military Uses of Autoinjection Devices

  • Military agents use autoinjectors to protect themselves from chemical warfare agents. 2-PAM (pralidoxime chloride) and atropine are used in the US military for first aid to fight nerve agents. These drugs are produced in two different autoinjectors by the nerve agent antidote kit. The administration process has become easier since one syringe now carries both medicines.
  • Service members US carry autoinjectors in concert with the diazepam and Mark|NAAK interjectors.


An Auvi-Q auto injector injection

Another design comes in a portable design which comes in the size and shape of a smartphone. Additionally, the design comes with voice instructions to help users use the autoinjector plus a retractable syringe. The Auvi-Q epinephrine uses this design.

The gas ject autoinjector is the new variant that propels jet liquid from above the skin without using the needle since it contains a pressurized gas cylinder. This aspect makes patients who fear needles become open-minded on trying these devices.  Various drugs are used once the autoinjector is loaded, even though insulin has been the only application for treating diabetes.
