Description

Technical Field

[0001] The utility model relates to the technical field of freezing devices, in particular to a low-temperature storage box for quick freezing of plasma. Background Art

[0002] Human plasma is a high-quality raw material for the production of blood preparation biological products. After the plasma is separated from the human body, it is required to be quickly frozen to below -20℃ for storage. The effect and time of quick freezing directly affect the effect and economy of blood preparation products. Generally, the plasma is required to be quick frozen to the specified temperature within 1 hour. Since the current daily quick freezing volume is 300 people, each person is 400cc of freshly drawn human blood, and 2 people are equivalent to 1kg weight. Each bag of plasma is required to be lowered from the human body temperature to below -25℃ within 6 hours after the human body is taken out. The basic working capacity and cycle of the blood station is to draw 40 people every 30 to 40 minutes, and the quick freezing time basically starts at 8 am. Therefore, the requirements for quick freezing devices are very high. The existing equipment cannot avoid releasing the cold air inside the equipment when placing plasma, which affects the work efficiency. Therefore, a low-temperature storage box for quick freezing of plasma is needed.

[0003] The patent document with the existing technical announcement number CN212030012U provides a plasma quick-freezing device, including a refrigerator, a support plate, a cold storage plate and a freezing rack. The support plate divides the internal storage space of the refrigerator into multiple parts at equal intervals in the vertical direction. Cold storage plates are installed on both sides of the support plate, and a quick-freezing space is formed between two adjacent support plates. The support plate is connected to the refrigerator through a slide groove. A cabinet door is provided on the refrigerator cabinet corresponding to each quick-freezing space. The cabinet door is pivotally hinged to the refrigerator. A cavity for accommodating plasma bags is provided on the freezing rack, and the freezing rack is placed on the cold storage plate. The plasma quick-freezing device provided by the utility model can realize large-scale and rapid freezing in one batch. The quick-freezing device is reasonably designed, effectively reduces the energy consumption required for quick freezing, and is easy to clean and maintain. However, when the CN212030012U technology is operated, it is impossible to effectively prevent the overflow of cold air during the multiple storage of plasma bags, thereby affecting the low-temperature preservation effect of plasma. At the same time, it is impossible to effectively improve the convenience of device operation and the sealing effect of the device. Therefore, a low-temperature preservation box for plasma quick freezing is urgently needed. Utility Model Content
