摘要:
A method for the real-time visualization and detection of extravasated and or infiltrated fluid and substances, including blood, that occur near the cannulation site of an injection is described wherein illumination or transillumination with near infrared light is used to image the contrast in real-time between absorbing and nonabsorbing subdermal and intradermal structures of blood vessels and remaining surrounding tissue, foreign substances and other structures in order to establish a baseline image of the body area of interest, and any new image is monitored and compared with the baseline image to detect the extravasation and/or infiltration of fluids and substances, including blood, around a vein or artery into the subdermal or intradermal tissue.

A method of modeling propagation of a pharmaceutical fluid in a patient, includes: collecting data corresponding to a time response curve resulting from injection of the fluid; and determining at least one mathematical model describing the data. The mathematical model can, for example, be a model which is not determined by a continuous or a discrete-time Fourier transform of the data. A method of controlling injection of a pharmaceutical fluid into a patient using an injector in a medical procedure, includes: collecting data corresponding to a patient response curve resulting from injection of the fluid; determining at least one mathematical model describing the data; and controlling the injector during the medical procedure to control injection of the fluid into the patient to create patient response at least in part on the basis of the mathematical model. A method of controlling injection of a contrast medium into a patient using an injector in a medical imaging procedure using an imaging scanner, includes: determining at least one mathematical model to predict a time enhancement response resulting from injection of the contrast medium; determining an injection protocol to approximate a predetermined time enhancement response in the patient by determining a constrained input solution to the mathematical model; and using the injection protocol to control the injector during the medical imaging procedure to control injection of the contrast medium into the patient to create an image of a region of interest.

摘要:
A system includes a parameter generation system to determine parameters of at least one phase of an injection procedure based at least in part upon a type of the injection procedure. The parameter generator system determines the amount of a pharmaceutical that is to be delivered to a patient at least in part on the basis of the concentration of an agent in the pharmaceutical and at least on part on the basis of a function that depends upon and varies with a patient parameter. The patient parameter can, for example, be weight, body mass index, body surface area or cardiac output. The pharmaceutical can, for example, include a contrast enhancing agent for use in an imaging procedure.

An injection system includes a fluid delivery system, a drive mechanism, a controller and a tubing set. The fluid delivery system includes a fluid container and a pumping mechanism having an inlet in fluid connection with the fluid container and an outlet. The tubing set is adapted to be placed in removable fluid connection with the outlet of the pumping mechanism and a patient. The drive mechanism is in operative connection with the pumping mechanism to pump fluid from the fluid container. First and second information stores, such as bar codes or RFID tags, are associated with the pumping mechanism and the tubing set, respectively. The controller is in operative connection with the drive mechanism and adapted to read the first information store and the second information store to at least partly control the operation of the drive mechanism based thereon.
摘要:
The fluid delivery system includes a pressurizing device for delivering injection fluid under pressure, a low pressure fluid delivery system, and a pressure isolation mechanism. The pressure isolation mechanism includes a first lumen associated with the pressurizing device, a second lumen associated with the low pressure fluid delivery system, and a pressure isolation port. The first valve is in a normally open position permitting fluid communication between the first lumen and the second lumen and movable to a closed position when fluid pressure in the first lumen reaches a predetermined pressure level. The first valve isolates the pressure isolation port from the first lumen in the closed position. A second valve is associated with the second lumen and regulates fluid flow through the second lumen. The second valve may be a disk valve defining one or more passageways in the form of slits through the body of the disk valve.

A hazardous fluid handling system which includes a housing having a radiation shielded internal chamber disposed therein which may accommodate a container holding a radioactive fluid, one or more radioactivity detectors positioned within the shielded internal chamber in operational proximity to the radioactive fluid in the container, and a dosimeter control device electronically coupled to the radioactivity detector(s) is disclosed. The dosimeter control device is operational for determining information regarding the radioactive fluid in the container based on individual measurements received from the one or more radioactivity detectors. The hazardous fluid handling system may be integrated into a patient support platform which includes a patient stimulus apparatus, an imager proximate the patient support platform, a radiopharmaceutical fluid delivery system for infusing a radiopharmaceutical fluid into a patient, a patient monitor to be associated with the patient, and an integrated system controller.
