Abstract: A new method for producing D-allulose crystals that allows for a continuous production process and ensures a high yield. Also, new D-allulose crystals. Further, the use of a nanofiltration unit in a method for producing D-allulose crystals to improve the yield and/or quality of the resulting crystals.

Abstract: This invention relates to the field of medical instruments and particularly to an apparatus used to apply cryotherapy to an injury. The apparatus is comprised of a vessel, a driver, and a directional controller. The vessel is configured such that when it is filled with a liquid and refrigerated, the resultant frozen solid formed within the vessel can be extruded via an exiting aperture. The driver forms a watertight seal with the vessel, allowing the vessel to be filled with liquid and frozen. The directional controller comprises flexible tabs that exert pressure on the sides of the frozen solid, limiting the movement of the frozen solid to one-way extrusion. The user applies force to the driver, thereby urging the frozen solid past the directional controller and out via the exit aperture.
