    Abstract: A syringe for a fluid delivery system includes a pressure jacket having a distal end, a proximal end, and a throughbore therebetween. The syringe further includes a rolling diaphragm having a proximal end with an end wall for engaging a plunger, a distal end received within the throughbore of the pressure jacket. A sidewall extends between the proximal end and the distal end of the rolling diaphragm along a longitudinal axis. At least a portion of one of the sidewall and the end wall has non-uniform thickness. At least a portion of the sidewall is flexible and rolls upon itself when acted upon by the plunger such that an outer surface of the sidewall at a folding region is folded in a radially inward direction as the plunger is advanced from the proximal end to the distal end of the rolling diaphragm.

    Abstract: A syringe assembly may include a syringe having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end, and a syringe drip guard extending around at least a circumferential portion of the sidewall between the distal end and the proximal end of the syringe. The syringe drip guard may have an outer wall protruding radially outward relative to the sidewall. A channel may be defined between the outer wall of the syringe drip guard and the sidewall of the syringe. The channel may have a closed proximal end and an open distal end. The syringe drip guard may be configured to at least one of: collect, absorb, or adsorb fluid within the channel.

    Abstract: A pressure sensor for use with a fluid delivery system having good sensitivity at low pressure, but also configured to remain in operating condition after being exposed to high pressures is disclosed herein. In one variation, the pressure sensor includes a fluid path set, a deformable element associated with the fluid path set and configured to deform in response to an external pressure, and a pressure transducer for monitoring deformation of the deformable element. In certain embodiments, the pressure sensor is configured to measure fluid pressure within the range of between about 0 mm Hg to about 300 mm Hg. However, the sensor pressure is also be configured to remain functional after being exposed to pressure in excess of about 60,000 mm Hg.
