Embodiment Construction
[0024] The main idea of the present invention is that since the current plasma quick-freezing machine takes about 2 hours to quickly freeze plasma to -30°C, or the same batch of plasma has different degrees of quick-freezing within 1 hour, it cannot guarantee that all plasma reaches -30°C. And it is impossible to verify whether the core temperature of each plasma bag reaches -30°C, so it cannot meet the requirements of the national standard. In order to solve this technical problem, the present invention adopts two evaporative refrigeration plates (upper cold plate and lower cold plate) made of stainless steel, and a thermal conductive soft pad is laid on the lower cold plate. First, make the temperature of the refrigerating plate reach -50°C when the plasma quick-freezer is working, and then clamp the plasma bag between the upper cold plate, the heat transfer cushion and the lower cold plate, and directly treat the plasma through the refrigerating plate that has reached -50°C...

The invention relates to a heat conduction cushion and a blood plasma instant freezer using the cushion. The heat conduction cushion comprises an upper layer film and a lower layer film, wherein a middle cavity is formed between the upper layer film and the lower layer film; the middle cavity is filled with a predetermined amount of refrigerant; the upper layer film and the lower layer film are sealed through a heat sealing process. By adopting the blood plasma instant freezer using the heat conduction cushion, each blood plasma bag can be stressed uniformly and is prevented from being deformed or broken in an instant freezing process, high temperature conduction performance and high heat conduction efficiency are realized, the blood plasma bags of the same batch can be instantly frozen rapidly and uniformly, and a good instant freezing effect is achieved.
Description
Technical field [0001] The present invention relates to the field of medical equipment, in particular to a thermally conductive soft pad and a plasma quick-freezer using the soft pad. Background technique [0002] In the medical field, plasma needs to be quick-frozen during storage, so plasma quick-freezers are needed to process plasma. At present, most of the plasma quick freezers sold on the market use air-cooled freezers, and the plasma bags are hung in the freezers for quick freezing. The quick-freezing standard of the national standard GB18469-2012.3.29 is: during the rapid freezing of plasma products, the core temperature of the plasma should be reduced to below -30°C within 1 hour. However, under normal circumstances, the existing plasma quick-freezer is used to freeze the plasma. It takes about 2 hours to quickly freeze to -30℃, and it is impossible to confirm whether the core temperature of the plasma bag reaches -30℃. [0003] The existing flat-plate plasma quick-freeze...
