Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] figure 1 It is a structural schematic diagram of a quick-freezing plasma device in the present invention. like figure 1 As shown, the device includes: a refrigeration shell 101, a metal container 102 built in the refrigeration shell 101, and a liquid refrigerant 103 placed in the metal container. Wherein, the liquid refrigerant 103 may be liquid ethanol, or liquid dimethyl sulfoxide (DMSO). In the embodiment of the invention, both the liquid ethanol and the liquid dimethyl sulfoxide can be an aqueous solution with a certain purity, or a liquid with 100% purity.

[0034] exist figure 1 In the shown device, the cooling housing 101 is a cooling device similar to a refrigerator or a freezer, and the metal container 102 is a container for ho...

Abstract

The invention discloses a device and a method for quickly freezing blood plasma. The device comprises a refrigerating shell, metal containers arranged in the refrigerating shell and liquid refrigerants filled in the metal containers, wherein the liquid refrigerants are liquid ethanol or dimethyl sulfoxide. By the technical scheme, the blood plasma can be quickly frozen.

Description

technical field [0001] The invention relates to the technical field of preparing frozen plasma, in particular to a device and method for quick-freezing plasma. Background technique [0002] As a blood preparation, human plasma is often used to replace the whole blood output to the wounded or patients, so as to replenish blood volume in time. [0003] Frozen plasma is currently available for clinical use, and frozen plasma can be stored for several years. [0004] The conventional preparation process of frozen plasma is to put the bagged plasma directly into the refrigerator or freezer, and freeze into shape after several hours. For example, if the bagged plasma is directly placed in a freezer at -30°C (Celsius), it generally takes about 12 hours to completely freeze. [0005] However, the above-mentioned solution of directly using a refrigerator or a freezer to freeze plasma requires a relatively long time for freezing the plasma, which is not conducive to ensuring the int...
