Through the use of Needle-free technology, those painful anesthetic injections are a thing of the past. Needleless injectors use CO2 or compressed air to propel a microjet of liquid six times the size of a 30-gauge needle through the skin. Instead of feeling the piercing pain of the needle, the patient only feels a slight pressure as the propelled liquid passes through the skin. Needle injections create a bulb of liquid once administered whilst it slowly gets absorbed into the surrounding tissue. Through the use of Needleless injectors, the liquid enters the skin as a mist for faster absorption and numbing as it get absorbed into the surrounding tissue.
