摘要： A powerhead (50) of a power injector is disclosed that includes a syringe housing (110) that contains a capacitive fluid detector (112). The capacitive fluid detector (112) may be operable to detect fluid within a syringe (116) installed on the syringe housing (110). The output of the capacitive fluid detector (112) may be used to estimate the volume of fluid within the syringe (116). The capacitive fluid detector (112) may include a plurality of discrete capacitors (118a-118h) arranged serially along a longitudinal axis (120) of the syringe (116). Each of the plurality of capacitors (118a-118h) may be operable to produce an electric field extending into the syringe (116). Each of the plurality of capacitors (118a-118h) may be formed on a printed circuit board (130).

摘要： A powered injector that stores energy at a low rate when not in use and delivers energy at a high rate during injection. Energy may be stored in a highly responsive energy storage device, such as a capacitor, for rapid delivery of power to the injector motor. In certain embodiments, wires connecting the powered injector to a power supply may be relatively small and inexpensive because the current and voltage loads placed on the wires are relatively low.

摘要： A contrast media injection system includes detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes. Additional features include using historical data to provide optimum pressure limit values during an injection protocol, a removable memory device for storing and transferring information such as injection protocols and injector statistics, and password protection of such protocols.

摘要： A multi-dose injection system (108) is disclosed that allows for vacuum-assisted removal of air from an interconnected tubing set (110) and syringes (126, 127) and subsequent filling with fluid. The injection system (108) may include a bulk fluid container holder module (116) operable to hold one or more bottles (118, 120) of fluid for administration to a patient. The holder module (116) may include a vacuum source (240) that is selectively fluidly interconnectable to the tubing set (110). Air may be removed from the tubing set (110) and syringes (126, 127) by fluidly interconnecting the vacuum source (240) to the tubing set (110). Then the vacuum source (240) may be fluidly isolated from the tubing set (110) and the bottles (118, 120) fluidly interconnected to the tubing set (110), thereby allowing fluid from the bottles (118, 120) to fill the at least partially evacuated tubing set (110) and syringes (126, 127).

摘要： A power injector that incorporates at least one signal transmission connector in a movable joint (e.g., between a powerhead and a support or stand; between at least one adjacent pair of support sections of a support for the powerhead) is disclosed. Such a signal transmission connector may be in the form of a slip ring module, but in any case is part of the signal transmission link to the powerhead. At least that portion of a signal transmission conduit that is adjacent to the powerhead may be disposed within the interior of the corresponding portion of the support or stand, thereby reducing the potential that an individual will grab onto the signal transmission conduit when attempting to move at least part of the power injector, to change the position of the powerhead, or both.

摘要： A hand-held remote for a medical fluid injector includes a syringe and a conduit which may be coupled to a pressure transducer on a control circuit of the injector. Movement of a plunger within a syringe body on the syringe creates a pressure which is sensed by the pressure transducer and the control circuit responds to the sensed pressure by causing fluid to be ejected from, or drawn into, a syringe mounted to the injector. The pressure developed by the remote provides tactile feedback to an operator for improved control over injections.
