Problems solved by technology

This method has an obvious technical disadvantage. The water circulation in the water bag is relatively slow. When the plasma bag (minus 25°C-minus 30°C) is placed between the two water bags, the water temperature in the water bag will immediately drop. The water circulation method The cooled water cannot be replaced immediately, causing the temperature around the plasma bag to be much lower than 37°C, and the plasma melting time (thawing time is within 30 minutes according to the plasma quality control management) is too long (greater than 30 minutes), and the required The more plasma dissolved at one time, the longer the time

Abstract

The invention provides a dry-type blood plasma unfreezing instrument. The dry-type blood plasma unfreezing instrument comprises a water tank, a heater and a water bag, wherein one end of the water tank is equipped with a metal bench, the other end is equipped with a boss, and the boss is higher than the metal bench; the heater is disposed inside the water tank; and the water bag is equipped with a water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe communicate with inside of the water tank respectively, and a water pump is disposed on the water inlet pipe. Through application of the dry-type blood plasma unfreezing instrument provided by the invention, blood plasma thawing time can be controlled within 30 minutes as required by blood plasma quality control. In this way, water bath unfreezing can be implemented; blood population is avoided; and operations become more convenient.

Description

technical field [0001] The invention relates to a dry plasma thawing instrument, which belongs to the field of medical auxiliary equipment. Background technique [0002] Now the usual way to thaw plasma is to put the plasma bag in a constant temperature water tank at 37°C to thaw. The advantage is that the plasma thawing time meets the requirements. The disadvantage is that the plasma bag is easily contaminated in the water, and the water stains must be wiped dry after taking it out. It adopts dry melting to prevent pollution and is easy to operate. [0003] The existing dry-type slurry melting apparatus generally uses two water bags to sandwich the plasma bag in the middle, and the water at 37°C in the tank is pumped into the two water bags by a circulating water pump to circulate in the two water bags to thaw the plasma. This method has an obvious technical disadvantage. The water circulation in the water bag is relatively slow. When the plasma bag (minus 25°C-minus 30°C)...
