Abstract
The present invention presents a hypodermic injection apparatus and methods to introduce an agent to a human body in a less painful way by activating inhibitory mechanisms for pain perception. The apparatus comprises a vibration assembly that encircles a needle penetration site, a removable and disposable barrier device that isolates the apparatus from a recipient and from a needle, a mechanical assembly for syringe movement and a power and control electronics housed in a handle assembly. The vibration assembly generates and delivers vibration to the recipient through a resonant vibration chamber that contacts the recipient via the barrier device. A syringe needle penetrates the recipient's tissue through a linear tubular conduit axially located in the vibration chamber. The needle penetration site is encircled by vibration and the needle is enclosed by the barrier device while being retracted from the recipient.
