Abstract: A system and method for automatically delivering an infusate to a patient is disclosed. The system includes an infusion set and an infusion device. A signaling component disposed on an infusion set component identifies an administration protocol for the infusion set. A detection device operatively connected to the infusion device detects the signaling component and identifies the administration protocol. The infusion device is then configured to operate according to the administration protocol.

Abstract: A medical delivery system (10) is provided for delivering a medicament (17) or fluid (17) to a patient. The system comprises a disposable element such as a line set (14) associated with a container (16) containing the fluid (17), an identifier (18) associated with the line set (14) and having identification information associated therewith, and a delivery device (12) configured to engage the line set (14) and deliver the fluid (17) to the patient. The delivery device (12) includes a recognition system (20) that is capable of obtaining the identification information associated with the identifier (18). The identification information may include information regarding the identification of the fluid (17), a type of line set (14), or a type of administration associated with the line set (14). The device (12) can be capable of configuration based on the identification information.

Abstract: A system and method is disclosed for controlling the input electrical current to an infusion pump stepper motor based on predetermined torque requirements. The system can include a motor controller and a non-volatile memory containing expected load torque values throughout a pump cycle. Responsive to the expected load torque values, the motor controller provides the stepper motor with a varying electrical current for overcoming load torque at each point in the pumping cycle. Additional factors can also be considered for varying the electrical current. These factors include, but are not limited to, temperature, pressure, and elapsed operating time.

Abstract: A medical infusion pump is disclosed which provides for greatly improved accuracy in the delivery of medicaments to a patient. Among the various features included in the instant invention is a pumping body which serves to deform and reform a tube so as to maintain the initial cross-section thereof and thereby preserve the output accuracy of the pump. Also disclosed with regard to the pumping body is a wholly mechanical synchronization of the pumping body and valves associated therewith and coactive with the aforementioned synchronization a mechanical linearization of output of the pumping body per each pumping cycle. Additionally, several features which serve to enhance the utility of the instant invention are also included therein among which is an associated assembly operative to automatically load or disload a tube or IV set into or out of the pumping body.

Abstract: A medical infusion pump is disclosed which has a tube present sensor that determines the position of the tube within a pumping body. The tube present sensor having a pivotable sensor arm with a blade which engages the tube. The pivotable sensor arm having a sensor flag which actuates an optical switch to signal that the sensor arm is in engagement with the tube. The sensor exchanges positional information with a pump controller to affect operation of the pump.
