This invention discloses an environmental sample preservation box based on phase change material (PCM) temperature control. The box includes a body with an inner liner and a sample holding chamber inside. The outer side of the inner liner is covered by a first PCM cold storage module, and the outer side of the sample holding chamber is covered by a second PCM cold storage module. This invention is applicable to the field of environmental sample preservation technology. It utilizes PCM cold storage for cooling, maintaining a constant temperature without any external power supply. This breaks through the dependence of traditional cold storage boxes on electricity, achieving truly passive operation, and is particularly suitable for field and emergency conditions. By setting two PCM layers with different melting points, it creatively transforms a large external temperature difference into a relatively stable internal temperature difference. The outer PCM module absorbs environmental thermal shock, while the inner PCM module precisely controls the sample temperature, achieving multi-level gradient temperature control. The PCM cold storage materials are integrated in a standard modular form, facilitating filling and replacement. The number of cold storage modules can be freely combined according to different transportation durations to meet different insulation time requirements.

This invention relates to the field of anatomical specimen preservation technology, and more particularly to a method for the long-term preservation of anatomical visceral specimens. The method includes: collecting environmental parameters, visual images, and attribute data of the specimens; generating a monitoring data set after standardization processing; constructing and updating an individual characteristic profile of the specimen based on this data set; performing a fusion analysis on the data set by combining pre-set weights corresponding to organ type and preservation method to generate a comprehensive status assessment result; inputting the data set and assessment result into a pre-constructed hybrid prediction model to output a future status prediction report with confidence scores; inputting the assessment result and prediction report into a pre-constructed hierarchical decision engine to generate personalized preservation and maintenance instructions; and finally, based on these instructions, performing adaptive regulation or triggering early warnings for the specimen preservation environment. This invention achieves individualized and precise assessment and proactive maintenance of specimen status, improving the stability and intelligence level of long-term preservation.
