Tri-axial mechanical test apparatus and method for simulating the process of freezing high-pressure water into ice
The present invention relates to a tri-axial mechanical test apparatus and method for simulating the process of freezing the high-pressure water into ice. The tri-axial mechanical test apparatus comprises a main body loading system, a freezing system, and a sample test system; in the main body loading system, a flange, an axial pressure piston and a pressure-bearing shell are constituted to a loading main body, and the axial pressure and confining pressure are controlled directly by a tri-axial servo tester and indirectly by an oil-water separator respectively; in the freezing system, a circumferential freezing liquid circulation channel and a base freezing liquid circulation channel are connected to an external cold source for cooling and freezing, and a dissoluble shell is provided on the periphery of the sample to ensure the shape of ice; in the sample test system, a serial of optical fiber sensors in the sample is connected to an optical fiber data collector, to measure temperature and strain. The present invention cooperates with a tri-axial servo tester, an oil-water separator, an external cold source and an optical fiber data collector, so that the water can be frozen into ice under pressure under the confinement of a dissoluble shell that is dissolved after an ice sample is formed, and then the tri-axial mechanical test can be carried out directly in the original stress state after water is frozen into ice under pressure.

Sterile sleeve for use in the production of surgical slush
A sleeve kit comprising a container sleeve and a sleeve cap which may be engaged with the container sleeve to form a sleeve assembly that envelopes a slush container, the sleeve kit including an attachment system to allow the sleeve cap to be engaged with the container sleeve to form the sleeve assembly and then become disengaged so that the slush container may be removed from the container sleeve. The attachment system may be a single-use attachment system to allow the sleeve cap to be engaged with the container sleeve to form the sleeve assembly. The container sleeve may have a set of at least one vent which allows air to move from an open top end of the container sleeve to a space between a bottom of an inserted slush container and a bottom of the container sleeve to facilitate removal of the slush container from the container sleeve.

Use of Sterile Sleeve in Production of Surgical Slush
Production of sterile therapeutic medium such as sterile surgical slush for use in surgery. A sterile slush container with a sterile sleeve assembly so that the outside of the sterile slush container remains sterile after placement in a non-sterile slush making machine so that the sterile slush container may be returned to the sterile field after removal of the sterile slush container from the sleeve assembly.
