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

Injection system with capacitive sensing

Systems and methods are presented for delivering medical fluids to a patient. A data storage device () is either separately attached to or incorporated within the structure of a reusable fixture that may be detachably connected to a barrel () of a syringe (). A filling station () and an power injector () may each include a read-write device () that is operable to read the data storage device () within its field of view. When the read-write devices () are attached to the filing station () and the power injector (), respectively, and when the fixture including the data storage device () is attached to the syringe (), the read-write devices () may be operable to store data on and read data from the data storage device () associated with the syringe (). After an injection procedure, the fixture may be detached from the syringe () and reused with a new or resterilized syringe ().

Reusable data storage fixtures for use with power injector syringe assemblies

The present invention relates to management of information relating to medical fluids, containers therefor, and medical fluid administration devices for administering such medical fluids to patients. Data tags (e.g., RFID tags) are generally associated with containers of the invention and may be electromagnetically read from and/or written to using an electromagnetic device, for example, that may be associated with a medical fluid administration device of the invention.

Systems and methods for managing information relating to medical fluids and containers therefor

An injection device () used in delivering medical fluids to a patient is provided. The injection device () may include a syringe plunger driver () and a syringe (). The syringe () may include a syringe data storage device (). The injection device () may include a communication device () disposable in each of attached and detached conditions. The communication device () may be operable to read a data storage device () within its field of view. When the communication device () is attached to the injection device () and the syringe () is installed on the injection device (), the communication device () may be operable to read the data storage device () associated with the syringe (). When in a detached condition, the communication device () may be operable to be hand manipulated such that various other data storage devices () may be read.

Medical fluid delivery system with RFID-equipped wand

A power injector syringe clamp assembly () is disclosed. This clamp assembly () includes a first clamp member () and a second clamp member (), where at least one of these clamp members () is movable to provide open and closed configurations for the clamp assembly (). The clamp assembly () also includes at least one RFID reader antenna for communicating with at least one RFID tag () on a power injector syringe (), at least when positioned within the clamp assembly ().

Power injector syringe clamp assembly with RFID antenna

An apparatus and method of operation is provided for a contrast media injector having a powered drive ram. The drive ram is designed to interface with a plunger of a syringe in order to move the plunger forward and backward relative to a barrel of the syringe. The syringe, having an RF data tag associated therewith, is mounted on to the contrast media injector. Electromagnetic signals are transmitted from an electromagnetic device of the injector in response to mounting the syringe. Data is electromagnetically read from the RF data tag of the syringe using the electromagnetic device of the injector. The transmitting is terminated after the electromagnetically reading. Medical fluid is then dispensed from the syringe. Electromagnetic signals are transmitted from the electromagnetic device in response to initiation of the dispensing. Data is electromagnetically written to the RF data tag of the syringe using the electromagnetic device of the injector.

Systems and methods for managing information relating to medical fluids and syringes therefor

The present invention includes medical fluid injector systems that detect the contents and/or volume of such contents within a syringe of the system. For example, an RF signal from a first antenna of a medical fluid injector may be transmitted through a syringe associated with the medical fluid injector. At least some of the transmitted RF signal may be received by a second antenna of the medical fluid injector. An amount of the RF signal received by the second antenna may be measured to provide information regarding the contents and/or volume of such contents within the syringe.

Syringe content detection using RF energy

The present invention relates to management of information relating to medical fluids, containers therefore, and medical fluid administration devices for administering such medical fluids to patients. Data tags (e.g., RFID tags) are generally associated with containers of the invention and may be electromagnetically read from and/or written to using an electromagnetic device, for example, that may be associated with a medical fluid administration device of the invention.

The invention, in one characterization, may be said to be directed to a radiopharmaceutical system. In some embodiments, the system may include a radioisotope elution component and a radio-frequency identification (RFID) tag coupled to the radioisotope elution component. Other embodiments may include a radiation shielded enclosure having an interior, an exterior, and a radio-frequency identification (RFID) communication transmission passage extending between the interior and the exterior.
