Plasma instant freezer

Abstract

The invention discloses a plasma instant freezer which is characterized a refrigeration plate is divided into a fixed refrigeration plate and a movable refrigeration plate. The fixed refrigeration plate is connected with the inner wall of a box cover, the movable refrigeration plate is arranged below the fixed refrigeration plate through a lifting mechanism, a refrigerator is connected with the refrigeration plates through cold guide pipes, a plasma tray is arranged on the movable refrigeration plate, fixed guide rails with protruding middles are arranged on two sides of the movable refrigeration plate, movable guide rails with the same shape as the fixed guide rails are arranged on the plasma tray corresponding to the fixed guide rails, guide supporting wheels are arranged on platforms at the front ends of the fixed guide rails and the rear ends of the movable guide rails, a displacement sensor is arranged above the box cover through a support, a position sensor replaces a pressure sensor to detect deformation of metal plates of a box body, the displacement sensor and an operation button are respectively connected with a controller through data lines, and a control circuit board is connected with a motor and the refrigerator. The plasma instant freezer has the advantages of being convenient to assemble, capable of reducing production cost, simple to operate, stable to move, rapid in freezing speed, large in instant freezing amount, high in automation degree, good in plasma instant freezing effect and the like.

Description

technical field [0001] The invention relates to a medical device, in particular to a blood plasma quick-freezing machine with convenient assembly, low cost and good freezing effect. Background technique [0002] As we all know, the chemical composition of plasma is mainly solute plasma protein, and contains electrolytes, nutrients, enzymes, hormones, cholesterol and other important components. The main function of plasma is to carry Blood cells transport the substances needed to maintain the life activities of the human body and the waste produced in the body, etc., which are necessary for cell growth and are necessary for saving lives and healing the wounded. The storage of plasma must be labeled and quick-frozen. Quick-freezing is the preservation of coagulation factors. The key processing steps of VIII, freezing rate and plasma core temperature are two key parameters. In order to ensure that the effective components of the plasma are not destroyed, special quick-freezing...

AI Technical Summary

Problems solved by technology

In order to ensure that the effective components of the plasma are not destroyed, special quick-freezing equipment should be used. It is best to reduce the central temperature of the plasma to below -30°C within 60 minutes, and the plasma bags should not be stacked. A box with a door, the lower end of the box is equipped with a refrigerator, the upper part of the box is equipped with a refrigeration plate on the wall, the refrigerator conducts cooling for the refrigeration plate through a fan or a conduit, and the upper end of the box is equipped with a The refrigerating plate and the rack chuck for hanging the plasma clip are used to freeze the plasma rapidly. The disadvantage of this plasma freezer is that the plasma bag cannot be compressed, the freezing capacity is small, the plasma after quick freezing is not suitable for preservation, and the work efficiency is low; 2. It is high production cost, slow freezing speed, and poor plasma preservation effect
