Abstract
A fluid injection system and a fluid verification system for confirming that a syringe, containing a fluid for injection, is fully filled with fluid and neither has free space (i.e., air) near the distal end thereof when the syringe is provided in an upright position nor contains air bubbles. Imaging processing techniques and systems are also provided to determine various injection parameters and to verify the type and certain properties of fluid that is present within a syringe.
Claims30
A syringe, comprising:
- a barrel comprising a distal end having a tapered, conical surface, wherein the barrel defines an interior volume configured to receive a fluid;
- and
- a plunger slideably disposed in the barrel to advance through the barrel to expel the fluid therefrom, the plunger comprising a distal surface, wherein at least a portion of the distal surface is tinted a conspicuous color to reflect incident electromagnetic radiation such that a reflected identification brightness pattern of the same conspicuous color is formed at a predetermined portion of the tapered, conical surface of the distal end of the barrel when the syringe is filled with the fluid.
A syringe, comprising:
- a barrel comprising a distal end and defining an interior volume configured to receive a fluid;
- and
- a plunger slideably disposed in the barrel,
- wherein at least a portion of a distal surface of the plunger is tinted a conspicuous color to reflect incident electromagnetic radiation such that a reflected identification brightness pattern of the same conspicuous color is formed at a predetermined portion of the distal end of the barrel when the syringe is filled with the fluid.
A method for identifying a property of syringe or fluid therein, comprising:
- providing a syringe comprising:
- a barrel comprising a distal end having an angled surface, wherein the barrel defines an interior volume configured to receive a fluid;
- and
- a plunger slideably disposed in the barrel, wherein at least a portion of a distal surface of the plunger is tinted a conspicuous color;
- exposing at least the portion of the plunger to electromagnetic radiation such that at least a portion of the electromagnetic radiation is reflected from the distal surface of the plunger to produce a reflected identification brightness pattern on a predetermined portion of the distal end of the syringe;
- and
- determining at least one property of the syringe or the fluid based on the reflected identification brightness pattern.
A system for indicating whether a syringe is ready for use in injecting a fluid therein into a patient, the system comprising:
- a syringe comprising:
- a barrel comprising a distal end having an angled surface, wherein the barrel defines an interior volume configured to receive a fluid;
- and
- a plunger slideably disposed in the barrel;
- and
- an electromagnetic radiation source provided to direct incident electromagnetic radiation onto at least a portion of a distal surface of the plunger,
- wherein at least the portion of a distal surface of the plunger is tinted a conspicuous color to reflect the incident electromagnetic radiation such that a reflected identification brightness pattern of the same conspicuous color is formed at a predetermined portion of the distal end of the barrel when the syringe is filled with the fluid, the reflected identification brightness pattern being indicative of at least one property of the syringe or the fluid.
