Patent attributes
A cold slurry syringe with enhanced features is provided for delivering a cold slurry into the human body. The syringe includes a syringe body for holding a volume of cold slurry, a plunger that slides within the syringe body for ejecting the cold slurry, and a tapered syringe head for delivering an even flow of cold slurry. An agitator can be added to keep the cold slurry from agglomerating and clogging the syringe. Insulation added around the syringe can keep the cold slurry from melting too quickly. A ball screw drive can be added to provide a smooth and consistent application of pressure as the cold slurry is delivered. The cold slurry flow can be enhanced by adding a streamline flow feature that reduces the occurrence of eddies or swirls inside the syringe. This feature can also help maintain the composition and consistency of the cold slurry.
