A syringe assembly comprising: a barrel having a dividing wall dividing the barrel into a fluid barrel and a retraction barrel, the fluid barrel includes a distal end and an open proximal end and a sidewall from the open proximal end to the distal end defining a fluid chamber; the retraction barrel includes an open distal end and a closed proximal end and a sidewall and the dividing wall forming a needle chamber the fluid chamber having a first cross-sectional width for retaining fluid and the needle chamber for housing a needle hub assembly, the dividing wall having a first aperture permitting fluid communication between the fluid chamber and the needle chamber; a needle hub assembly disposed within the needle chamber, the needle hub assembly comprising a needle hub, a needle cannula attached to the needle hub in fluid communication with the first aperture, a second conduit that extends from an open end of the needle cannula to a second aperture of the needle chamber, the needle cannula biased to move in the proximal direction by a biasing element, the dividing wall including a supporting element the supporting element is a perpendicular tab that is disposed on the dividing wall and extends into the needle chamber to engage the needle hub and a ramped portion disposed on the dividing wall that extends into the fluid chamber, the supporting element applies a force in the distal direction to the needle hub so that the needle cannula extends beyond the open distal end of the retraction barrel in a positioned in first position; and a plunger rod disposed within the fluid chamber comprising a distal end, a proximal end, a stopper disposed at the distal end of the plunger rod for forming a fluid-tight seal with the inside surface of the barrel, a plunger rod body extending from the distal end to the proximal end, and the dividing wall comprises an opening that permits the perpendicular tab to flex outwardly into the fluid chamber as the plunger rod interacts with the ramped portion of the dividing wall and cause the biasing element to retract the needle cannula to be housed within the needle chamber in a second position. a barrel having a dividing wall dividing the barrel into a fluid barrel and a retraction barrel, the fluid barrel includes a distal end and an open proximal end and a sidewall from the open proximal end to the distal end defining a fluid chamber; the retraction barrel includes an open distal end and a closed proximal end and a sidewall and the dividing wall forming a needle chamber the fluid chamber having a first cross-sectional width for retaining fluid and the needle chamber for housing a needle hub assembly, the dividing wall having a first aperture permitting fluid communication between the fluid chamber and the needle chamber; a needle hub assembly disposed within the needle chamber, the needle hub assembly comprising a needle hub, a needle cannula attached to the needle hub in fluid communication with the first aperture, a second conduit that extends from an open end of the needle cannula to a second aperture of the needle chamber, the needle cannula biased to move in the proximal direction by a biasing element, the dividing wall including a supporting element the supporting element is a perpendicular tab that is disposed on the dividing wall and extends into the needle chamber to engage the needle hub and a ramped portion disposed on the dividing wall that extends into the fluid chamber, the supporting element applies a force in the distal direction to the needle hub so that the needle cannula extends beyond the open distal end of the retraction barrel in a positioned in first position; and a plunger rod disposed within the fluid chamber comprising a distal end, a proximal end, a stopper disposed at the distal end of the plunger rod for forming a fluid-tight seal with the inside surface of the barrel, a plunger rod body extending from the distal end to the proximal end, and the dividing wall comprises an opening that permits the perpendicular tab to flex outwardly into the fluid chamber as the plunger rod interacts with the ramped portion of the dividing wall and cause the biasing element to retract the needle cannula to be housed within the needle chamber in a second position.
