INFORMATION SENSING SYRINGE
First Claim
1. A syringe system comprising:
- a syringe body comprising a proximal open end and at least one distal discharge outlet, the syringe body being configured to house a liquid substance;
a plunger positioned in the syringe body forming a seal with an inner wall of the syringe body;
an injector piston configured to be received by the proximal open end and to slide within the syringe body, the injector piston being configured to engage the plunger as it slides within the syringe body to expel the liquid substance through the at least one discharge outlet; and
at least one sensor configured to measure at least one property of the liquid substance.

Abstract
Syringe systems and flow control systems configured to detect information associated with a liquid material are described. The syringe systems may include a syringe body for housing the liquid material and an injector piston for expelling the liquid material out of the syringe through a discharge outlet at a distal end of the syringe body. Components of the syringe, such as an injector piston, may include sensors configured to measure and/or detect a property of the liquid material, such as concentration, pH, or radioactivity. The flow control system may include a pinch valve and a platen arranged about a fluid delivery channel. Flow within the fluid delivery channel may be controlled by increasing (squeezing the fluid delivery channel) or decreasing the distance between the pinch valve and the platen. Components of the flow control system may include detectors configured to detect properties of fluid in the fluid control channel.

9. A device for automatically injecting a radioactive liquid substance, the device comprising:
-
a syringe comprising; a syringe body comprising a proximal open end and at least one distal discharge outlet, the syringe body being configured to house a liquid substance, and a plunger arranged within the syringe body forming a seal with an inside surface of the syringe body; an injector piston configured to be received by the proximal open end and to slide within the syringe body, the injector piston being configured to engage the plunger as it slides within the syringe body to expel the radioactive liquid substance through the at least one discharge outlet; at least one sensor configured to measure at least one radioactive property of the radioactive liquid substance; and a syringe shield covering at least a portion of the syringe body. - View Dependent Claims (10, 11, 12, 13, 14)

15. A fluid delivery channel flow control system comprising:
-
a force concentration element and a platen arranged to opposedly contact a fluid delivery channel positioned therebetween; and a force assembly configured to move one of the force concentration element and the platen in a first direction to reduce a distance therebetween, thereby generating a pressing force on the fluid delivery channel and reducing a flow of a fluid within the fluid delivery channel, and in a second direction to expand the distance, thereby reducing at least a portion of the pressing force on the fluid delivery channel and increasing the flow of the fluid within the fluid delivery channel. - View Dependent Claims (16, 17, 18, 19, 20)
