Thermostatic oscillation thawing device

Abstract

The invention provides a thermostatic oscillation thawing device comprising an inner cleaning box, a blood plasma bag support board and a top support ring; the inner cleaning box is movably installedinside the main box body; eight nozzles are symmetrically fixed on an inner side of a water spray ring. The installing of the inner cleaning box is good for increasing the thawing efficiency; water will be sprayed out of the blood plasma bag through the nozzles on the water spray ring at the end of a water spray pipe so as to thaw the blood plasma in the blood plasma bag; the nozzles are uniformlydistributed outside the blood plasma bag so that the warm water is uniformly sprayed out, which is good for uniformly thawing blood plasma; In the process of thawing, the vibrating motor will drive the inner washing tank to constantly vibrate slightly on the top of the first spring, which will drive the second spring and the plasma bag support board to constantly vibrate on the inside of the inner washing box. This allows the plasma to loosen due to oscillations in the plasma bag, effectively increasing 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
