Abstract

A syringe pump configured to at least partially surround a syringe loaded into the pump. The syringe pump including a syringe pump housing defining a syringe receptacle shaped and sized to accept loading of the syringe, a plunger driver assembly configured to manipulate a plunger of a syringe loaded into the syringe pump, and a syringe housing including a syringe barrel shield pivotably coupled to the syringe pump housing configured to at least partially enclose a syringe loaded into the syringe pump within the syringe receptacle, and a syringe plunger tray and lid assembly operably coupled to the syringe pump housing and configured to at least partially enclose a portion of the plunger driver assembly.

Claims10

Dependent claims

A syringe pump, comprising:

a housing;
a powertrain having a lead screw;
a clutch assembly including:
first and second half-nuts;
a cam having a first lobe and a second lobe, the first lobe operable to move the first and second half-nuts into engagement with the lead screw and the second lobe operable to move the first and second half-nuts into disengagement with the lead screw, wherein the first lobe is adjacent to the second lobe along a length of the cam;
and
a leaf spring in communication with at least one of the first and second half-nuts;
and
a plunger driver assembly including:
a flipper configured to be movable between a capture position and an open position;
a trigger connected to both the clutch assembly and the flipper;
and
a biasing element configured to bias the flipper into the capture position.
