Blood preservation device based on intermittent refrigerating principle

Abstract

The invention relates to the technical field of medical treatment and discloses a blood preservation device based on the intermittent refrigerating principle. The blood preservation device comprises apreservation box body, refrigerating layers are arranged in the preservation box body, main gears and auxiliary gears are arranged in the preservation box body, right threaded rods are movably installed at the ends, away from left threaded rods, of main threaded rods, movable bearings are movably connected to the ends, away from the main threaded rods, of the right threaded rods, squeezing rods are movably connected to the ends, away from the right threaded rods, of the movable bearings, and refrigerating boxes are movably connected to the ends, away from the movable bearings, of the squeezing rods. According to the blood preservation device based on the intermittent refrigerating principle, cold air is released through the refrigerating boxes to carry out cold preservation on blood; andmeanwhile, through reset structures in the squeezing rods, the inner refrigerating boxes can restore and close refrigerating when not stressed, intermittent refrigerating is carried out on blood storage pipes in the preservation box body, and it is avoided that the internal activity of blood is damaged as the temperature is too low.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a blood preservation device based on the principle of intermittent refrigeration. Background technique [0002] Blood is a kind of red opaque viscous liquid flowing in human blood vessels and heart. With the increasing number of safety accidents, the demand for fresh blood is also increasing, and the problem of blood transportation and storage is also increasing. Come on. [0003] At present, the storage of blood is generally stored at ultra-low temperature. The long-term freezing of blood loses its activity, and when ultra-low temperature storage is used, the blood needs to be thawed and thawed for a long time before it can act on the patient; Coagulation damages and deteriorates. Therefore, the timing of blood refrigeration needs to be well grasped, and when blood is stored, in order to maintain activity, the blood needs to be shaken to prevent blood coagulation. [0004] Th...

Problems solved by technology

[0003] At present, the storage of blood is generally stored at ultra-low temperature. The long-term freezing of blood loses its activity, and when ultra-low temperature storage is used, the blood needs to be thawed and thawed for a long time before it can act on the patient; Coagulation damages and deteriorates. Therefore, the timing of blood refrigeration needs to be well grasped, and when blood is stored, in order to maintain activity, the blood needs to be shaken to prevent blood coagulation.

[0004] Therefore, we propose a blood storage device based on the principle of intermittent refrigeration, which realizes the oscillation and intermittent cooling of blood, and avoids the ultra-low temperature storage used in traditional blood storage devices, which easily loses blood activity. Achieve uniform intermittent refrigeration and uniform shaking to avoid coagulation of fresh blood
