Use of Sterile Sleeve in Production of Surgical Slush

A method for production of sterile surgical slush outside of a sterile field and subsequent delivery of sterile surgical slush to the sterile field;

• the method comprising:
• placing a quantity of sterile saline into a non-sterile slush making device located outside of the sterile field, the sterile saline contained in a slush container, a set of interior and exterior surfaces of the slush container starting as sterile;
• the slush container enveloped by a sleeve assembly comprising a container sleeve that covers at least a portion of the slush container and a sleeve cap engaged with the container sleeve, the sleeve assembly is initially sterile but an exterior of the sleeve assembly is deemed not sterile not later than once the sleeve assembly with slush container is placed into the slush making device;
• removing the slush container enveloped by the sleeve assembly from the slush making device after conversion of the sterile saline to sterile surgical slush;
• separating the sleeve cap from the container sleeve to expose a portion of the slush container;
• and
• maintaining the slush container as sterile while removing the slush container from the container sleeve and moving the slush container into the sterile field so that the slush container may be opened and the sterile saline slush may be used when needed.
