ANGIOGRAPHIE-SPRITZE MIT MEHRFACHREDUNDANTEN PROZESSOREN

摘要

A method for injection of medical fluid into a patient, providing an angiographic injection device; entering at least one patient value into the device prior to an injection; calculating within the device at least one injection parameter in response to said entered patient value; and displaying said calculated injection parameter to a user of the device prior to the injection; wherein at least two computers are operatively connected to the device to provide independent at least dual redundancy. There is also disclosed an angiographic injector system, comprising: a device for injecting a medical fluid into a patient; control means operatively connected with said device for controllably causing said device to inject said medical fluid in response to at least one injection parameter, wherein said control means includes at least two computers providing independent at least dual redundancy; input means suitable for receiving an input signal corresponding to a patient physiological value and for providing a patient value signal in response thereto; calculating means operatively connected to receive said patient value signal and for determining a patient related injection parameter in response thereto; and display means operatively connected with said calculating means for displaying said patient related injection parameter external of said injection system.
