Syringe holder device for controlled force amplification syringe fluid flow

Claim 1

A syringe holder for loading with a cylindrical syringe having a syringe barrel with a unitary flange structure and for facilitating the axial advancement of the syringe barrel plunger from a retracted position to continuously advanced dispensing positions, including axially aligned barrel and plunger housing sections, the barrel housing having the form of an open-sided open-ended part cylinder dimensioned to receive, support and stabilize the syringe barrel in coaxially mounted relation, the barrel housing comprising slot means dimensioned to receive the flange structure of a syringe barrel thus loaded into the holder and to thereby stabilize the barrel against axial dislocation with respect to the barrel housing, the plunger housing having cylindrical form with an open end and a closed end defining an open zone dimensioned to receive the retracted plunger of the loaded syringe barrel, said closed housing end including a central aperture to accommodate insertion therethrough of a spacing bar on an axial line within the plunger housing, and means for applying force against the head of the plunger comprising spacing bar torque means and a spacing bar having leading and trailing ends and a shank, the shank and the closed end of the plunger housing being threaded for threadably engaging the spacing bar within the central aperture such that torquing the bar achieves controlled biasing movement of the leading end of the spacing bar against the syringe plunger head located within the plunger housing.
