Blood plasma thawing apparatus and blood plasma thawing automatic control method

Abstract

The invention provides a blood plasma thawing apparatus and a blood plasma thawing automatic control method. The blood plasma thawing apparatus comprises a thawing device, a constant-temperature cold water machine set and a controller, wherein after being heated in the constant-temperature cold water machine set, water forms an external circulation together with the thawing device; temperature sensors are arranged in the simulation blood plasma bag of the thawing device and the constant-temperature cold water machine set for monitoring the treatment process and thawing condition of the thawed blood plasma in real time; the operation time and temperature are recorded and displayed; cold water and hot water prepared by the professional constant-temperature cold water machine set are supplied to the thawing device; an advanced and reliable intelligent control method is adopted, so the thawing process is safe and effectively; and thus, a complete blood plasma thawing quality management system can be constructed conveniently. The entire apparatus adopts a modular structure, the parts of the apparatus have high specialty and stable performance, and thus, the conventional product can be upgraded and the cost of a user is reduced; and because a plurality of heating program modules are arranged according to the specifications and quantity of blood plasma bags and requirements of a thawing process, the thawing is more specific, the operation is intelligent and more convenient and reliable, and energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to an instrument for plasma thawing treatment. Background technique [0002] At present, the plasma thawing instruments on the market all use water or air as the heat exchange medium for heat treatment. Due to the lack of monitoring means for the actual temperature of the plasma in the plasma treatment in the past, the heat exchange medium can only be controlled by experience when using it. The relationship between plasma temperature and processing time cannot be strictly regulated. 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 thawing is completed, and the heat exchange medium temperature cannot reflect the overall temperature inside the plasma bag in real time. If the temperature is too high or too low, and the processing time is too short or too long, it will cause loss of plasma componen...

Problems solved by technology

According to clinical requirements, the plasma stored below -20°C needs to be heated to above 26°C in a short period of time to keep the plasma composition unchanged, and it should not exceed 42°C to cause damage to the plasma, and fibrin precipitation will occur if the thawing temperature is uneven.

At present, the blood thawing instruments on the market all have an independent thawing box or a thawing box plus a heating box. The heating adopts a direct or single-cycle method. The temperature stability and heating characteristics of the heat exchange medium cannot strictly meet the requirements. The above temperature characteristics are also one of the keys to the safety and effectiveness of the thawing instrument

[0003] At the same time, in the actual use process, the specifications and quantities of plasma bags thawed each time are generally different, and it is more complicated and difficult for the operator to artificially select the thawing temperature and time. Improper use will lead to potential safety hazards in plasma quality
