Thermostatic oscillation thawing device

Abstract

The invention provides a constant temperature oscillating thawing instrument, which includes an inner cleaning box, a plasma bag support plate and a top support ring; an inner cleaning box is movably installed on the inner side of the main box; the inner side of the water spray ring is fixed and symmetrically installed There are eight nozzles. The setting of the inner cleaning box is conducive to improving the thawing efficiency. When in use, the water will be sprayed outwards to the outside of the plasma bag through the nozzle on the water spray ring at the end of the water spray pipe, so as to thaw the plasma in the plasma bag, and the nozzle will be uniform Distributed on the outside of the plasma bag, the sprayed warm water is more evenly distributed, which is more conducive to the uniform thawing of the plasma, and the vibration motor will drive the inner cleaning box to vibrate slightly on the top of the No. 1 spring during the thawing process, which will drive the second The number spring and the plasma bag support plate vibrate continuously inside the inner cleaning box, so that the plasma in the plasma bag is continuously loosened due to oscillation, thereby effectively improving the thawing efficiency.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a constant temperature oscillating thawing instrument. Background technique [0002] The thawing instrument is also called a plasma melting machine. At present, the plasma thawing instrument on the market uses water or air as the heat exchange medium for heat treatment. Due to the lack of monitoring methods for the actual temperature of the plasma in the plasma treatment, it can only be used based on experience. Controlling the heat exchange medium cannot make strict regulations on the relationship between plasma temperature and processing time during processing. Plasma is packaged in bags, and there is a large lagging temperature difference between the core temperature and the medium temperature during the processing process, that is, before the completion of thawing. The temperature of the heat exchange medium cannot reflect the overall temperature inside the plasma bag...

AI Technical Summary

Problems solved by technology

[0005] Based on the above retrieval findings, its two patents combined with most thawing instruments in the prior art at the same time, which has the following problems in use: the existing thawing instruments all use warm water to contact the plasma bag when thawing the plasma in the plasma bag. To thaw it, put the plasma bag into the thawing device first, then pass the external warm water at 37°C to the inside of the thawing device and flow outside the plasma bag. When thawing the plasma in the plasma bag, it can only be Thaw slowly from the outside to the inside, and the temperature of the warm water inside will drop rapidly after contacting the plasma bag, and the water will be discharged at a slower rate, which will affect the thawing rate of the plasma bag
