Patent ID: 7396344

Claim:
A syringe pump assembly comprising: a mechanized syringe including a barrel, a plunger disposed within said barrel for reciprocating movement therein, and a motor operatively coupled to said plunger for effecting mechanized movement of said plunger; and an anti-rotation clamp secured to said syringe and constructed and arranged to prevent rotation of said syringe by contacting a structure adjacent to said syringe, said anti-rotation clamp comprising: a clamp body comprising: a spring arm extending generally in an arc having a first end and a second end; a protrusion projecting from said spring arm proximate said second end thereof; and a deflection arm connected at a first end thereof to said first end of said spring arm and having a second end disposed in spaced relation with respect to said protrusion, said deflection arm being constructed and arranged such that relative movement of said protrusion and said second end of said deflection arm away from each other effects a corresponding circumferential contraction of said spring arm and relative movement of said protrusion and said second end of said deflection arm toward each other effects a corresponding circumferential expansion of said spring arm; and an actuating device engaged with said protrusion and said deflection arm and constructed and arranged to, upon manipulation thereof, effect relative movement of said protrusion and said second end of said deflection arm with respect to each other to thereby cause a corresponding circumferential contraction or expansion of said spring arm.
