摘要:
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. An injection system for use in angiography includes a source of saline, a pump in fluid connection with the source of saline to pressurize the saline, a saline valve in fluid connection via a first port thereof with an outlet of the pump, a first connector in fluid connection with a second port of the saline valve, a source of contrast, a contrast valve in fluid connection with the source of contrast via a first port of the contrast valve, a powered injector in fluid connection with a second port of the contrast valve, a second connector in fluid connection with a third port of the contrast valve, and a pressure isolation mechanism.

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.

A pressure isolation mechanism for use in a medical procedure includes a lumen, an isolation port in fluid connection with 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.

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 preferably spring-biased in the first state and is switchable to the second state when fluid pressure in the lumen reaches a predetermined pressure level. Alternately, an actuator can control the state of the valve. A pressure transducer can be in fluid connection with the isolation port of the pressure isolation mechanism. A fluid delivery system includes a syringe and a pressure isolation mechanism as described above.

An apparatus for removing casings from sausages having a frame, and a conduit extending within the frame through which a string of linked sausages are longitudinally moved. A knife means is pivotally mounted in the longitudinal path of the linked sausages and is capable of moving into the recessed portions of the string existing between adjacent ends of the linked product to sever the casing material in that area. A spin jump paddle is pivotally and transversely mounted in the path of the string of sausages downstream from the knife element so that the casings will pass thereover. The paddle has a width greater than its thickness and will rotate from a flat position to a vertical position depending on the portion of a linked product that is passing thereover. The casing material being removed from the linked product passes over the paddle and downwardly to a pair of gripping rolls. Steam is injected into the conduit and diverted through the length thereof to loosen the casing material from the cooked product.

A system for dispensing fluid for a food product includes a valve-less fluid block including one or more internal air passages defined within its interior with each air passage configured to operatively couple with an air source. The block includes one or more internal dispensing passages defined within the block interior. Each dispensing passage is configured to operatively couple with a flow channel. The flow channel is disposed external to the block and is configured to operatively couple with a fluid source. The dispensing passages are disposed and further configured in fluid communication with the air passages within the interior of the block and place the flow channels in fluid communication with the air passages. A port is defined in the block and is adapted to dispense fluid from the interior of the block.
