Abstract
The invention discloses a freeze-drying plasma device. The device comprises an inner barrel, blood storage columns, an air inlet channel, isolation valves, condensation chambers and a vacuum pump; anouter barrel sleeves the outer side of the inner barrel through the top end of the inner barrel, and the air inlet channel penetrates through the outer barrel to communicate with the inner barrel; anactivated carbon filter screen, a nano fiber filter screen and a stainless steel filter screen are sequentially inlaid in the inner cavity of the air inlet channel, wherein the outer ends of a Y-shaped channel are correspondingly connected with the condensation chambers through the isolation valves, and the outer end sides of the condensation chambers are connected with refrigerating compressors through pipelines; and the vacuum pump is connected to the Y-shaped channel on the front side of the isolation valves through the pipelines, and a spiral heating tube is arranged at the bottom of the inner side of the outer barrel. The spiral heating tube is used for keeping the inner barrel in a relatively constant temperature, and the vacuum pump is used for enabling the interior of the inner barrel to be vacuum; the air in the inner barrel is replaced by a fan and the vacuum pump, so that the quality of air in the inner barrel is improved; and the plasma in the inner barrel is frozen by utilizing the refrigerating compressors.
Description
technical field [0001] The invention belongs to the technical field of plasma freezing and medical equipment, and in particular relates to a freeze-drying plasma device. Background technique [0002] Freeze drying is the best method for preserving biologically sensitive tissues. The freeze dryer is suitable for the drying of bacteria, viruses, plasma, serum, antibodies, vaccines, pharmaceuticals, microorganisms, yeast, and plant extracts for biological research. Through freeze drying, tissues, tissue extracts, bacteria, vaccines, and plasma The material becomes dry, so that no enzymatic, bacterial and chemical changes will occur. [0003] The inventor found similar patents on plasma freeze-drying in the process of searching for patents. For example, in the Chinese patent application number: 201420336899.X, a new type of horizontal plasma freezing storage box is disclosed, including a box body , a box door, a box, a control system, and three special fans, the box door is hi...
