Abstract: Described herein is an add-on device for an intravenous (IV) set hand pump comprising a first member configured to actuate the handpump, a second member hingedly connected to the first member and configured to receive the hand pump, wherein, when actuated, the add-on device is configured to increase a fluid flow rate downstream of the IV set hand pump beyond a maximum gravity-based fluid flow rate of the IV set.

Abstract: Pump assemblies for use with an IV set are described herein. A pump assembly includes a rotatable crank, a piston rod, and a diaphragm assembly. The crank includes a crank profile defining a plurality of lobes. The piston rod includes a first follower and a second follower spaced apart from the first follower. The rotation of the crank relative to the piston rod causes the piston rod to reciprocate relative to the crank. The diaphragm assembly includes a housing and a diaphragm member. The diaphragm member is coupled to the housing and cooperatively defines a volume in fluid communication with the IV set. The diaphragm member is movable between an extended position configured to draw in fluid from the IV set and a contracted position configured to expel fluid into the IV set. The diaphragm member is coupled to the piston rod to reciprocate the diaphragm member.

Abstract: An IV blood set foot pump includes a base plate, a squeezing plate movably coupled to the base plate by a pivot member and a biasing member coupled to the base plate and the squeezing plate. The biasing member is configured to exert a biasing force against the squeezing plate when the biasing member is in a compressed state. One of the base plate and the squeezing plate comprises a cavity configured to receive an IV pump bulb. IV sets with IV blood set foot pumps and methods of operating IV blood set foot pumps are also provided.
