摘要： Disclosed are systems, apparatus and methods for determining information related to analyte(s) (e.g., concentration) in a sample such as biological fluid. An analysis system for determining information relating to at least one analyte in a sample of biological fluid can be configured to: withdraw the sample of biological fluid from the source of biological fluid; interrupt the flow of infusion fluid while the sample of biological fluid is withdrawn; analyze the withdrawn biological fluid to determine information relating to at least one analyte; and resume the flow of infusion fluid after the sample of biological fluid is withdrawn. A method of interrupting flow of an infusion fluid without triggering an alarm can comprise, while the flow of the infusion fluid is interrupted, diverting the flow of the infusion fluid from a fluid passageway to an expandable volume at a rate that maintains constant flow from an infusion pump.

摘要： The present invention comprises methods and apparatuses that can provide measurement of glucose and other analytes with a variety of sensors without many of the performance-degrading problems of conventional approaches. An apparatus according to the present invention comprises a blood access system, adapted to remove blood from a body and infuse at least a portion of the removed blood back into the body. Such an apparatus also comprises an analyte sensor, mounted with the blood access system such that the analyte sensor measures the analyte in the blood that has been removed from the body by the blood access system. A method according to the present invention comprises removing blood from a body, using an analyte sensor to measure an analyte in the removed blood, and infusing at least a portion of the removed blood back into the body. The use of a non-contact sensor with a closed system creates a system will minimal infection risk.

摘要： A microneedle insertable in a target cell tissue, including a manipulative end maintained exterior of cell tissue and an insertion end positionable in or adjacent of target cell tissue. A plurality of microtubes are bundled to pass through the needle body and extend to respective distal ends grouped proximally interior of the insertion end. A sensing fiber is extendable from means for sensing for passage through the needle body to a distal end capable of sensing cell tissue parameters. The insertion end and the bundled microtube and sensing fiber distal ends are positionable in or adjacent of cell tissue thereby providing rapid evaluation of cell parameters by optic fiber sensing, fiber sampling of cell parameters, and precise delivery of therapeutic fluids or additional treatment measures. A method is also disclosed of precisely positioning a microneedle having a plurality of microtubes and sensing fibers therein for evaluating and treating cell tissue.

摘要： The present invention embodies a method and an injector adapted to incorporate this method, for keeping a patient's vein open during an intravenous contrast injector procedure without injecting a saline solution from a separate syringe. The injector includes a controller having a programable software module to allow an operator to configure the injector to push some contrast media fluid through an injection site and then retract a plunger drive ram. A syringe is adapted to allow a patient's blood pressure to move the syringe plunger back towards its starting position, thus enabling a patient's blood to pass through the injection site. Alternatively, the syringe is adapted with an elastic plunger which as it enlarges and contracts facilitates fluid communication through the injection site. Additionally, the plunger drive ram can be adapted to gradually pull as well as push the plunger, thereby causing fluid to flow across the injection site.

摘要： A needless connector is provided which utilizes a resealable preslit septum valve. The valve is resiliently restrained relative to a housing with the valve and housing configured to accept a standard male luer lock having a luer tip which penetrates the valve through the opening to extend within the housing and a luer locking flange of the luer lock extending about the housing. The valve includes a disk shaped upper portion covering the opening, a lower portion spaced from the housing and extending downward from the disk shaped portion into a passageway defined by the housing, and an annular skirt to attach the septum to the housing. The connector exhibits satisfactory leak pressure after multiple connections and disconnects to the luer lock fitting and long periods of indwell of the luer tip.

The medical infusion pump (10) includes a pumping mechanism (250) and a pump chamber (132) in an operative position with respect to the pumping mechanism (250), the pumping mechanism (250) manipulating the pump chamber (132) to pump liquid through the pump chamber. An electric motor (256) having a rotatable drive shaft (316) is operably linked to the pump driving mechanism (250) and the pump driving mechanism (250) pumps a select amount of liquid through the pump chamber (132) on each rotation of the electric motor drive shaft (316). The improved electric motor assembly (256) includes a motor having a portion of a drive shaft (388) extending therefrom. A magnet (392) is attached to the extending portion of the drive shaft for rotation with the drive shaft. A flux gatherer (396) is spaced from and magnetically coupled to the magnet (392) for biasing the poles of the magnet in a select orientation relative to the flux gatherer (396) so as to stop the pump driving mechanism (250) in a select position. A magnetic position detector (400) is spaced from and magnetically coupled to the magnet (392) for emitting an electrical signal each rotation of the drive shaft (388).

摘要： A method for use in an intravenous tube assembly comprises the steps of automatically monitoring liquid flow along a fluid flow path extending through an intravenous catheter to detect at least a partial cessation of flow along the fluid flow path and, upon detecting a diminution of liquid flow along the fluid flow path, automatically feeding an anticlotting agent to the fluid flow path. An assembly for implementing the method takes the form of a systolic actuator for dividing the fluid flow into successive aliquots which can be timed. The systolic actuator extracts energy from the fluid stream and monitors the stream via the extracted energy. Alternatively, a pressure device is operatively connected to the catheter for automatically detecting at least a partial cessation of liquid flow along a fluid flow path extending through the catheter. The assembly also includes a feeder mechanism operatively connected to the catheter and the sensing device for automatically feeding an anticlotting agent to the fluid flow path through the catheter upon a detection by the sensing device of a diminution of liquid flow along the fluid flow path and, more particularly, of intravenous liquid flow in a distal direction into a patient's circulatory system.
