摘要： An infusion data communication system provides a communication link among a fluid container, an infusion pump, and a patient through which identification data may be communicated. Data devices are located at the fluid container and the patient and conduct low frequency RF energy at a low power level containing the data into the medical fluid. The data-laden RF energy propagates through the medication fluid to data readers at the infusion pump which receives the RF energy and reads the data. A comparison is made to verify that the right medication is mounted to the infusion pump for administration to the right patient. RFID devices may be used for the data devices and readers. Pump programming data may also be propagated to the infusion pump from the container RFID tag. The RFID device at the patient may be writable and may be used to store a patient MAR.

摘要： A system and method of accurately pumping a fluid using tubing of variable inner diameter and material is disclosed. The disclosed pump comprises a pumping mechanism configured to compress and release a portion of a flexible tube to cause fluid to flow along the flexible tube, a gauging apparatus, and a vacuum apparatus. The gauging apparatus is configured to determine the inner diameter of the flexible tube, which value is used in calibrating the pumping rate of the pump. The vacuum apparatus is configured to reduce the ambient pressure in a volume surrounding the portion of the flexible tube, thereby causing the flexible tube to fully expand to its original outside diameter when the flexible tube is released by the pumping mechanism.

摘要： A pump having a disposable fluid contacting portion which defines a fluid inlet and outlet and a fluid path there between. The pump includes a drive portion configured to engage the disposable portion to cause fluid to be moved from the fluid inlet to the fluid outlet. The disposable portion is configured to be selectively coupled to the drive portion. The disposable portion includes a driven membrane which forms a portion of the fluid path, and the drive portion includes a drive membrane. The two membranes are vacuum coupled to each other, whereby movement of the drive membrane causes the driven membrane to move, causing fluid to be pumped through the disposable portion. The pump has particular utility in the medical field for moving fluid from a source to a patient. The pump may include features such as an air-trap, bubble detection, fluid flow controls, and pressure detection.

摘要： A system and method for determining whether the pressure in a fluid line upstream of an infusion pump is becoming lower as pumping draws fluid from the fluid line and fluid container due to a lack of proper venting. An initial pressure is sensed by an upstream pressure sensor at the start of an infusion. After a period of time, which may be determined either by monitoring infusion time or the number of pump cycles completed, a second pressure is sampled and compared to the initial pressure. Various analytical methods may be applied to the sensed pressures to determine upstream pressures or trends. Where an upstream pressure reading indicates a lack of proper venting, an alert signal is provided. Continuous monitoring may occur in which succeeding samples are compared to preceding samples to determine upstream pressures or trends.

摘要： A pumping segment of a fluid line alternately in fluid communication with the upstream and downstream portions of the fluid line connects a fluid supply to a fluid receiver. A pressure sensor located downstream of the segment monitors the pressure during the segment's communication with the upstream and downstream ends. The pressure difference is used to establish a pressure threshold against which the average pressure is compared to determine if an upstream occlusion exists. Should the average pressure fall within a cautionary zone, the pump is reversed to examine the pressure difference once again. Based on the pressure difference during the reversal, a pressure threshold line may be adjusted thereby adapting to fluid administration conditions.

摘要： Flow parameters in a fluid delivery assembly are determined by monitoring pressure responses and processing those responses along with information regarding the fluid flow. In one aspect, a processor controls the pump to pump flow quantities in accordance with a pseudorandom code. Portions of the resulting pressure signal sensed are then decoded in accordance with the pseudorandom code. An estimate of the equilibrium pressure is generated from the decoded pressure values, while a summation of the pressure samples is generated from the undecoded pressure signals. The resistance to fluid flow of the system is determined from the estimated equilibrium pressure and pressure summation. For low flow rates, a processor controls the pump to pump fluid in a series of fluid boluses, with each fluid bolus delivered in the beginning of a separate timeslot. The equilibrium pressure is measured at the end of each timeslot, and a summation of the pressure samples is generated from the pressure signals. For high flow rates, the pump is controlled to vary the flow rate and the change in pressure is divided by the change in flow to directly determine the resistance. A resistance display continuously displays the resistance of the system. The pseudorandom coding and decoding can be used to filter out pressure-response crosstalk caused by multiple fluid infusion segments feeding into a common line.

摘要： A system for increasing the volumetric flow uniformity of fluid pumped through a conduit by an infusion pump. A pumping mechanism operates in identifiable step movements that are broken down into microstep movements that are then grouped into packets. The pumping mechanism controls the period of each microstep, so that the sum of the microstep periods in a packet is essentially equal to the packet period, with little or no waiting time on the motor. The motor preferably begins moving the assigned microsteps in each packet immediately upon the beginning of the time period, but controls the period of the microsteps for that packet.

摘要： An air ejection system usable with a pressure vessel for a pumping segment for fluid flow and for incorporation into a fluid delivery system. The air ejection system includes a vane positioned directly in the fluid flow path to redirect flow into the pressure vessel to wash out air bubbles that may accumulate there. In one aspect, the vane is shaped to provide a redirected flow to wash the entire internal area of the pressure vessel. In another aspect, the vane is shaped so that when the pressure vessel is loaded by a pressure sensor, the redirected flow path has a uniform cross-sectional area throughout its entire length.
