Injector system with a manual control device
First Claim
1. An injector system comprising:
- 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 source of injection fluid for supplying to the pressurizing chamber; and
a manual control device in operative connection with the powered injector, the manual control device comprising at least one actuator, the manual control device comprising a preprogrammed injection mode wherein depression of the actuator causes the powered injector to deliver a preprogrammed injection of injection fluid, and wherein the manual control device is adapted to stop an injection procedure if no force is applied to the actuator.

Abstract
An injector system includes a powered injector, a pressurizing chamber in operative connection with the powered injection, a fluid path in fluid communication 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 therewith. An injection system for use in angiography includes a source of saline, a pump in fluid connection with the source of saline to pressurized the saline, a source of contrast, a contrast valve in fluid connection with the source of contrast, a powered injector in fluid connection with the contrast valve, and a pressure isolation mechanism.

15. A fluid path set for use in a fluid delivery system, comprising:
-
a multi-patient use section adapted for connection to a pump device and to a source of injection fluid; and
a per-patient use section adapted for removable fluid communication with the multi-patient use section, the per-patient use section comprising a pressure isolation mechanism comprising a first port adapted for connection to the pump device via the multi-patient use section, a second port adapted for connection to the patient, and a pressure isolation port adapted for connection to a source of medical fluid via the multi-patient use section, a lumen connecting the first port and second port, and a valve member biased to a normally open position permitting fluid communication between the lumen and the pressure isolation port, and movable to a closed position when fluid pressure in the lumen reaches a predetermined pressure level sufficient to overcome the biasing force applied to the valve member. - View Dependent Claims (16, 17, 18)

19. A pressure isolation mechanism, comprising:
-
a housing defining a lumen and a pressure isolation port; and
a valve member disposed within the housing, the valve member biased to a normally open position permitting fluid communication between the lumen and the pressure isolation port, and movable to a closed position when fluid pressure in the lumen reaches a predetermined pressure level sufficient to overcome the biasing force applied to the valve member. - View Dependent Claims (20)
