Overview of Injector pen

An injector pen is a device used for injecting medication under the skin. It consist of a chamber or cartridge of medication, a tip to attach a needle, and a piston or plunger to inject the dose. Some injector pens include dials to adjust the dose of the injection before each administration. Injector pens are designed to make injectable medication easier to use and improve patient compliance. They are commonly used for multiple-dose therapies, and some pen injectors come with a supply of disposable needles. Autoinjectors are another type of self-injectable device that enclose prefilled syringes or cartridges which are driven by a spring system. Injector pen materials are made from DuPont polymers that facilitate ease of use and miniaturization. There are also risks associated with using pen injector technology. Overall, injector pens are an essential tool for administering injectable medications safely and effectively.
