Abstract: Disclosed herein is a syringe pump, wherein the syringe pump comprises a half nut assembly that engages a motor driven lead screw, where a barrel cam with a projection engages a slot in the half nut cam follower surface so as to make the half nut engage or disengage with the lead screw. Also disclosed are related methods using the syringe pump, such as a method for removing effects of slack in a syringe pump having a syringe loaded on the syringe pump.

Abstract: A method for removing the effects of slack in a syringe pump having a syringe loaded on the syringe pump, the syringe having a barrel and a plunger disposed within the barrel, the method comprising receiving a target flow rate of the syringe loaded on the syringe pump, determining a therapy actuation speed corresponding to the target flow rate, actuating the plunger of the syringe out of the barrel at a first predetermined speed until a force sensor coupled to the plunger measures a force that is less than a first predetermined force threshold, actuating the plunger of the syringe into the barrel at a second predetermined speed greater than the therapy actuation speed until the force sensor coupled to the plunger measures a force that exceeds a second predetermined threshold, and actuating the plunger of the syringe into the barrel at the therapy actuation speed.

Abstract: A method for discharging fluid from a syringe and for mitigating occlusion conditions includes actuating the plunger of a syringe into a barrel. The method monitors fluid pressure within the barrel of the syringe and determines that an occlusion exists when the fluid pressure exceeds a predetermined threshold. The method actuates the plunger out of the barrel by a predetermined amount in response to the detected occlusion and actuates the plunger of the syringe into the barrel until a measured fluid pressure within the barrel of the syringe exceeds another predetermined threshold.

Abstract: HEMODIALYSIS SYSTEM A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly. Figure 32
