摘要： A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes at least one optical sensor assembly configured to sense the movement of the pump assembly, a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.

摘要： A method for filling a reservoir a filling assembly having a needle, and a fluid. The reservoir is in a disposable housing assembly with a septum fluidly connected to the reservoir, a septum access assembly having a first position covering the septum and a second position providing access to the septum, and a bias mechanism for biasing the septum access assembly to the first position. The method includes piercing the septum with the needle, inserting fluid to the reservoir through the needle, contacting the filling assembly to the septum access assembly, and removing the needle from the septum. Removing the needle from the septum allows the bias mechanism to move the septum access assembly from the second position to the first position. The disposable housing assembly is attached to a reusable housing assembly.

摘要： A syringe pump includes a lead screw, a motor, and a sliding block assembly. The lead screw has threads and the motor is coupled to the lead screw to rotate it. The half-nut housing has a half nut and a barrel cam. The half nut is disposed within the half-nut housing. The half nut has half-nut threads at an end adjacent to the lead screw void. The half nut engages or disengages with the threads of the lead screw. The half nut includes a half-nut cam-follower surface and a half nut slot. The barrel cam is disposed within the half-nut housing and engages with the half-nut cam-follower surface. The barrel cam includes a pin to fit within the half nut slot such that the barrel cam rotates between a first position and a second position to actuate the half nut between the engagement position and the disengagement position, respectively.
