摘要： PROBLEM TO BE SOLVED: To provide a fluid delivery system equipped with a manual controller to feed back pressure in a fluid path to an operator tactually, and to provide a pressure isolation mechanism and an injector control mechanism. SOLUTION: A manual controller of an injector system includes an actuator to control the injector by force applied by the operator. The actuator gives the operator tactual feedback of pressure in the fluid path by connecting the fluid path to the fluid so as to permit fluid communication therebetween. The pressure isolation mechanism includes a first state generated when a lumen and an isolation port are connected and a second state generated when they are separated. A valve is usually in the first state and is switchable to the second state when fluid pressure in the lumen reaches predetermined pressure. A pressure transducer 980 can be connected to the isolation port of the pressure isolation mechanism so as to permit fluid communication therebetween. The fluid delivery system includes a manual syringe and the pressure isolation mechanism. COPYRIGHT: (C)2007,JPO&INPIT

摘要： The control device is used to control delivery of fluid from a fluid delivery system during a medical injection procedure. The fluid delivery system includes an injector adapted to actuate a syringe used to deliver the injection fluid to a patient. The control device is operatively associated with the injector for controlling discrete flow rates of injection fluid delivered to the patient. The control device includes a housing and an actuator associated with the housing. An electronic substrate is disposed within the housing and comprises a conductive pattern. The actuator is adapted for operative association with the conductive pattern. The conductive pattern includes a plurality of predetermined digital values corresponding to discrete flow rates of injection fluid to be delivered by the injector, such that when the actuator is actuated the actuator operatively associates with the conductive pattern for transmitting the digital values to the injector.

摘要： An injector system includes a source of injection fluid, a pump device, a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device operatively associated with the fluid path set. The fluid control device is adapted to permit purging of air from the fluid path set and to stop flow of the injection fluid to a patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The fluid control device is preferably part of the fluid path set between the source of injection fluid and the pump device. In another aspect, an injector system includes a powered injector, a pressurizing chamber in operative connection with the powered injector, a fluid path in fluid connection with the pressurizing chamber, and a manual control in fluid connection with the fluid path. The manual control includes at least one actuator for controlling the injector through application of force by an operator. The actuator provides tactile feedback of pressure in the fluid path to the operator via a fluid connection with the fluid path. A pressure isolation mechanism for use in a medical procedure includes a lumen, an isolation port in fluid connection with the lumen, and a valve having a first state and a second state. The first state occurs when the lumen and the isolation port are connected. The second state occurs when the lumen and the isolation port are disconnected. The lumen remains open for flow of fluid therethrough in the first state and in the second state. The valve is normally in the first state and is switchable to the second state when fluid pressure in the lumen reaches a predetermined pressure level. A pressure transducer can be in fluid connection with the isolation port of the pressure isolation mechanism. A fluid delivery system includes a manually operated syringe and a pressure isolation mechanism as described above.

摘要： The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.

The valve is normally in the first state and is switchable to the second state when fluid pressure in the lumen reaches a predetermined pressure level. A pressure transducer can be in fluid connection with the isolation port of the pressure isolation mechanism. A fluid delivery system includes a manually operated syringe and a pressure isolation mechanism as described above.
