Abstract: A retrograde disposable intravenous (IV) set is disclosed. The IV set includes a diverter housing between upper and lower portions of a fluid line, the diverter housing including a lower end and an upper end extending away from the lower end and the fluid line to a syringe port located in the upper end, and a diverter member within the diverter housing and configured to move within the diverter housing from a first position, at which a first opening through the diverter member forms a first fluid pathway between the upper portion and the lower portion of the fluid line, to a second position, at which the first fluid pathway is blocked and a second fluid pathway is formed between the upper portion of the fluid line and a syringe port. Retrograde infusion may occur when the diverter member is in the second position.

Abstract: Systems for use with a medical device for controlling an infusion device are provided. In one aspect, a system includes an infusion device that is configurable with operating limit parameters for providing medication to a patient, and a limiting system. The limiting system receives laboratory information associated with a patient, compares current operating parameters of the infusion device with the operating limit parameters in view of the laboratory information for the patient before and during administration of the medication to the patient by the infusion device, determines that administration of the medication by the infusion device should be prevented based on comparing the operating parameters with the operating limit parameters in view of the laboratory information and, responsive to determining that the operation should be prevented, prevents the administration of the medication by the infusion device, and generates a notification indicating that the operating limit parameters require modification.

Abstract: Systems and methods are provided for intermittent microinfusion. A system may include a pump and an IV set that includes a y-port valve disposed below a pump interface portion of the IV tubing. The y-port valve may include an internal valve member that allows fluid to flow from the pump to a patient when no syringe is attached to the y-port. The internal valve member may be moved by the attachment of a syringe containing the medication to be infused to the y-port such that the fluid pathway from the pump to the patient is blocked and fluid from the syringe can be injected into the IV tubing between the y-port valve and the pump. The pump may retrograde pump the medication into the tubing via the y-port valve and then forward pump the medication to the patient when the syringe is removed from the y-port.

Abstract: A patient care system comprising an interface unit, a Patient Controlled Analgesia (PCA) unit, and a pulse oximetry unit is disclosed. The PCA unit provides PCA administration, including administration of a dose of analgesic upon request, and the pulse oximetry unit provides constant monitoring of the patient's blood oxygen saturation level and pulse rate. The interface unit provides for communication between and control of the PCA unit and the pulse oximetry unit, and further provides an interface between the user and the system. When the pulse oximetry unit indicates to the interface unit that the patient's blood oxygen saturation level and pulse rate has reached a user-specified minimum, the interface unit initiates visual and audio alarms and controls the PCA unit by shutting off the PCA unit. The interface unit also contains communication ports, which the interface unit can use to send signals to external devices, such as to alert alerts medical personnel.

Abstract: In accordance with the present invention, a modular patient care system provides patient monitoring and the supply of therapeutic requirements. Specifically, the system is comprised of an interface unit and a plurality of patient functional units. The interface unit provides an interface between the user and the system, and may be configured and adapted to provide different levels of functionality. Interface units with different levels of functionality may be interchanged so as to provide greater flexibility, safety, and cost effectiveness. Each interface unit contains interface ports for the transfer of information such as drug libraries, system configuration values, and event history. The functional units are internally programmed and controlled so as to provide a high level of system modularity, and require only power and interfacing functionality from the interface unit.

Abstract: An apparatus for infusing TPN fluids to a patient includes a source of fluid, a pump for infusing fluid from the source to the patient, and a computer for controlling the operation of the pump. During the operation of the apparatus the infusion rate of the pump is varied according to an infusion regimen that is based on the volume of fluid to be infused and the time during which the fluid is to be infused. This regimen is characterized by a trifurcated ramp up region having interrelated incremental rates of infusion which transition the pump from a zero rate of infusion to a steady state rate of infusion. The infusion regimen is also characterized by a period of steady state infusion which follows the ramp up region, and a ramp down region in which the infusion rate is decremented from the steady state rate based on the remaining volume of fluid to be infused to the patient and the remaining time for infusing this remaining volume of fluid.

Abstract: A system for withdrawing a predetermined volume of fluid from a patient comprises a filter assembly which is connected in line for fluid communication between an artery and a vein of the patient. A pump having a fluid chamber is connected in fluid communication with a filtrate port of the filter. Operation of the pump causes the withdrawal of fluid from the filter and into the pump chamber at a preselected volumetric rate. Periodically, the pump is cycled to expel the withdrawn fluid from the pump chamber. The system further comprises a fluid collection device for collecting the expelled fluids and may include means for replenishing fluids to the patient.
