Abstract:
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.
Abstract:
A system for delivering fluid to a patient includes a hazardous material enclosure suitable for holding a first container comprising a first fluid, and a pump device capable of pumping the first fluid from the first container and a second fluid from a second container. The hazardous materials enclosure has a cap which includes a flexible sealing member that cooperates with the first container to create a biohazard seal during connection of the first container to the cap. The system further includes a mixing device associated with the pump for mixing the first and second fluids for delivering the fluid mixture to the patient.
Abstract:
A combined fluid injection and inflation system is disclosed and includes a fluid delivery system including at least one pressurizing device, a fluid path, and a control unit. The fluid path is adapted to connect the pressurizing device to a patient via a catheter including a balloon and inserted in the patient. The control unit is operable to control the fluid delivery system. In operation, the control unit selectively actuates the fluid delivery system to operate in a fluid injection mode or in a balloon inflation mode. In the fluid injection mode the pressurizing device delivers fluid to the fluid path for a fluid injection procedure. In the balloon inflation mode, the pressurizing device delivers fluid to the fluid path for inflating the balloon associated with the catheter. An operator control may be connected to the control unit for controlling the fluid delivery system and may be a handheld device.
Abstract:
An integrated radiopharmaceutical patient treatment system is disclosed including a patient support platform with an associated 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 a patient, and an integrated system controller operably associated with the patient stimulus apparatus, imager, radiopharmaceutical fluid delivery system, and patient monitor to control and coordinate their operations. Within the patient treatment system the radiopharmaceutical fluid delivery system may be included comprising a radionuclide supply module, a radiopharmaceutical processing module, a quality control module, a patient injection module, and a controller. A hazardous fluid handling system including a docking station and a hazardous fluid transport device adapted to detachably dock with the docking station is further disclosed.
Abstract:
A method and device for the simultaneous or sequential introduction of multiple fluids into the bloodstream including a multiple lumen catheter with corresponding multiple hole sets. By introducing a second fluid such as saline, the concentration and bolus of a first fluid, such as a contrast agent, can be controlled and optimized.
Abstract:
A system for producing a contrast-enhanced medical image of a patient includes a source of a contrast or enhancement medium, a pressurizing unit in fluid connection with the source of contrast or enhancement medium, an energy source operable to apply energy to a region of the patient, an imaging unit providing a visual display of an internal view of the patient based upon a signal resulting from the energy applied to the region of the patient, and a control unit. In an embodiment, the signal is affected by a condition of the contrast or enhancement medium in the patient. To control the procedures, the control unit adjusts the condition of the contrast or enhancement medium in the patient based upon the signal. A communication interface preferably enables information between an injector subsystem and an imaging subsystem.
Abstract:
A syringe for use with a powered injector to inject a fluid into a patient inclides an encoder. The encoder includes at least a first indicator positioned on the encoder. The first indicator is adapted to interact with at least a portion of energy being propagated through or adjacent the encoder in a manner that is detectable. The presence (or absence) of the first indicator provides or corresponds to information about the syringe configuration. The indicator(s) of the present invention can, for example, provide information about syringe configuration by the number and/or position thereof. A plurality or set of such syringes can be provided, with the configuration of each such syringe being represented by the presence or absence of indicator(s) of that syringe.
Abstract:
Hyperthermia has been applied by, for example, separate ultrasound transducers, RF or microwave transmitters and heated fluids. Imaging by separate MRI imaging coils is usually used to view the anatomical region under treatment. Separate temperature probes (needles, catheters) are often used to monitor tissue temperature. Control of the temperature profile required for effective hyperthermia treatment is usually done by trial and error, involving a human operator. The present invention combines all of these capabilities into a single device, which is MRI compatible and safe. It also allows for automatic control of the RF energy to achieve a prescribed tissue hyperthermia.
Abstract:
A system for dispensing a medium includes at least a first container to hold the medium, a pressurizing device, such as a pump, in fluid connection with the container for pressurizing the medium, and an agitation mechanism or device to maintain the components of the medium in a mixed state. The container and the pressurizing device can be separate units, as in the case of an bag or bottle in fluid connection with a peristaltic or other type of pump. The container and the pump can also be combined in a single unit, as in the case of a syringe, wherein the syringe barrel of the syringe acts to contain the medium and the syringe plunger pressurizes the medium within the syringe barrel. A method of injecting a multi-component medium includes the step of agitating the medium (for example, as described above) before or during an injection procedure to maintain the components of the medium in a mixed state.
