Estimating the term…
A syringe pump which includes a pusher block is slidably mounted on bearings on one or more guide rails. The pusher block is advanced or retracted by a lead screw having an axis which is offset from the axis of the one or more guide rails which are supported at their respective ends by support blocks, wherein forward and/or trailing sides of the pusher block bearings are extended, and wherein the guide rail support blocks include recesses for accommodating the extended ends of the pusher block slide bearings. In another embodiment, the syringe pump includes quick connect-disconnect fixtures for loading and unloading syringes. Other mechanical and programmable improvements are described in the specification.
A syringe pump in which a pusher block is slidably mounted on bearings on one or more guide rails, wherein the pusher block is advanced or retracted by a lead screw having an axis which is offset from the axis of the one or more guide rails which are supported at their respective ends by support blocks, wherein forward and/or trailing sides of the pusher block bearings are extended, and wherein the guide rail support blocks include recesses for accommodating the extended ends of the carriage slide bearings.
A syringe pump in which a pusher block is slidably mounted on one or a plurality of guide rails, the improvement which comprises a set of tool-free quick connect/disconnect for facilitating loading and unloading of syringes from the pump.
The syringe pump as claimed in 2, wherein the quick connect/disconnect includes a thumb-screw, knob or locking cam for drawing side tabs of the flange capture bracket against either a pusher block or a syringe holder block.
A syringe pump in which a pusher block is slidably mounted on one or a plurality of guide rails, and further including a tool-free quick connect/disconnect syringe barrel clamp.
A syringe pump in which a pusher block is slidably mounted on one or a plurality of guide rails, and including a syringe holder and clamp mounted on an extension bar, wherein the syringe holder and clamp is slidably adjustable with respect to the pusher block to accommodate a variety of syringes and syringe sizes.
A system of syringe pumps comprising a master pump and one or more satellite syringe pumps, wherein the satellite syringe pumps are controlled and powered by the master pump, and wherein electrical power and controls for operation of the one or more satellite pumps are distributed from the master pump.
A method for maintaining smooth and consistent flow rates to and from a syringe pump, which comprises output from at least two syringes into a single flow channel, and operating the at least two syringes in a coordinated and sequential order in order to maintain a consistent flow rate or pressure.
A method of operating one or more syringe pumps which comprises pulsing the syringe pumps to mimic physiologic characteristics.
A syringe pump system in which syringe actuation forces are controlled through look-up table in a computer library.
A method for controlling a syringe pump, which comprises comparing actual syringe movement to a theoretical desired value, and adjusting said syringe movement to approximate said theoretical value.
