1. A syringe pump comprising:
a flange clamp coupled to a mating surface of a syringe pump body, wherein the flange clamp is configured to be spaced apart from the mating surface to receive a syringe flange of a syringe and the flange clamp is coupled to the syringe pump body with a fastener that extends through the flange clamp to engage a bearing block disposed within the syringe pump body;
a sensing switch extending through the mating surface, wherein the sensing switch is configured to be in a closed state when the flange clamp is in contact with the sensing switch in response to an absence of the syringe flange of the syringe disposed between the flange clamp and the mating surface, and in an open state when the flange clamp is spaced apart from the sensing switch to receive the syringe flange of the syringe; and
a spacer disposed between the flange clamp and the mating surface.
