摘要:
A hazardous fluid transport container and a hazardous fluid delivery system are disclosed. The hazardous fluid transport container includes a housing enclosing an at least partially shielded enclosure. First and second fluid path elements are disposed within the housing, with the first fluid path element and second fluid path element fluidly coupled together. A pump unit may be provided for dispensing fluid from the first and second fluid path elements optionally into a third fluid path element. Also, methods for priming the hazardous fluid transport container and for mitigating laminar flow injection bolus spreading are disclosed. Additionally, disclosed is a radioactive fluid transport container for a syringe or other container. The radioactive fluid transport container allows the syringe or container to be used in an injection procedure without removal from the container.

A system for the collection, management, and dissemination of information relating at least to a medical procedure is disclosed. The system includes a user interface adapted to provide raw data information at least about one of a patient, the medical procedure, and a result of the medical procedure. A medical device communicates with the user interface, receives the raw data information from the user interface, and generates operational information during use. A central database communicates at least with the medical device and receives data from the medical device. The central database is used to create related entries based on the raw data information and the operational information and optionally transmits the related entry to the medical device or the medical device user. The related entry includes information that provides guidance based on previously tabulated, related medical procedures. A system for the iterative analysis of medical standards is also disclosed along with methods for the evaluation of medical procedures and standards.
摘要:
A delivery apparatus useful for infusing a therapeutic agent into a body lumen, the apparatus including a lumenal body defining at least one infusion port for infusing the therapeutic agent into the body lumen, and a sensing element which is distal of the at least one infusion port and adapted to sense the amount of infused therapeutic agent or any compound derived therefrom in the body lumen. Another embodiment of the apparatus includes a lumenal body defining at least one infusion port for infusing the therapeutic agent into the body lumen, and a filtration element which is distal of the at least one infusion port and adapted to deliver a reaction agent which may react with the therapeutic agent in the body lumen. A sensing element may be provided distal of the filtration element for sensing the amount of infused therapeutic agent or compounds derived therefrom in the body lumen.

摘要:
A device for injection of a fluid into a patient includes a container adapted to hold the fluid and defining an outlet through which the fluid can exit the container. A pressurizing mechanism is in connection with the container for pressurizing the fluid, and an actuator is in fluid connection with the outlet. The actuator has a first state in which fluid is prevented from flowing through the outlet and a second state in which fluid can flow through the outlet. The injection device further includes a flow regulator to control the flow rate of fluid in fluid connection with the outlet. The container, the pressurizing mechanism, the actuator and the flow regulator can be MR compatible, thereby making the device suitable for use in or near the bore of an MR scanner.
摘要:
A method of substituting an MRI incompatible pump for delivering fluid to a patient with an MRI compatible pump, both pumps being microprocessor controlled. The first pump operates upon administration tubing for pumping fluid from a source thereof to the patient. The method includes the steps of: providing the second pump to be substituted for the first pump; providing second tubing having a portion thereof that is operable to function with the second pump; connecting the second tubing to the administration tubing to establish an altered fluid path from the source to the patient, the altered path including portions of both the administration and second tubing; placing the second pump for operation upon the second tubing to enable the second pump to pump the fluid through the altered path according to programming thereof; and disconnecting the first pump from the administration tubing before bringing the patient into the MRI environment.

摘要:
A system for delivering a fluid comprising cells to tissue of a patient, includes: a least a first container for holding an injection fluid in which the agent is carried; a first powered drive in operative connection with the container, the first powered drive being operable to pressurize contents of the container; a control system in operative connection with the first powered drive and operative to control the first powered drive; a fluid path in fluid connection with the container, the fluid path including a patient interface adapted to deposit the cells within tissue of the patient; a sensor system; and a communication system in connection with at least the control system and the sensor system. The communication system is adapted to provide information to the control system. The control system in adapted to transmit a control signal to at least the first powered drive based at least in part on information provided to the control system. The cells can for example be pregenitor cells or stem cells.
摘要:
A device for detecting a venous structure or vessels in a patient or animal.
