Auto-Injectors Discharge Demonstration


Understanding the Operation of Auto-Injectors

In this controlled environment demonstration, we will showcase the discharge process of three auto-injectors. Please note that this demonstration is for educational purposes only and should not be attempted at home. It was conducted under experimental conditions to illustrate how these devices function safely.

Auto-Injectors Overview

Examining the Three Auto-Injectors

We will demonstrate the operation of the following auto-injectors:

  • Jext Auto-Injector: Displaying the needle discharge, drug delivery, and needle safety feature.
  • EpiPen Auto-Injector: Highlighting needle activation, drug expulsion, and needle cover for safety.
  • Emerade Auto-Injector: Showing needle deployment, drug release, and needle cover mechanism.

Jext Auto-Injector

Needle Discharge and Drug Delivery

Watch as we apply pressure to the Jext auto-injector, causing the needle to fire and expel the drug into the patient. When turned on its side, observe the safe removal of the needle with a protective cover to eliminate sharps risk.

EpiPen Auto-Injector

Effective Needle Safety Mechanism

With the EpiPen auto-injector, pressing against the mesh initiates needle discharge and drug release. Witness the needle cover in vibrant orange completely shielding the needle during removal, reducing the risk of sharps injuries.

Emerade Auto-Injector

Extended Needle and Safety Measures

The Emerade auto-injector features a longer needle compared to Jext and EpiPen. When pressed, the needle deploys, and the drug is discharged. Turning it on its side, observe the needle's safe withdrawal, accompanied by the slide-out needle cover for comprehensive needle protection.

It's important to note that during this demonstration, the adrenaline's force caused slight discomfort to the patient, resulting in a reflexive reaction. Proper restraint is essential to ensure the needle remains in place until the drug is fully administered.
