Freeze-dried reagent manufacturing process for preventing deliquescence of freeze-dried reagent balls and freeze-dried reagent

Abstract

The invention relates to the field of freeze-dried preparations in the field of biological medicines, in particular to a freeze-dried reagent manufacturing process for preventing deliquescence of freeze-dried reagent balls. According to the manufacturing process, the surfaces of the freeze-dried reagent balls are coated with paraffin through a coating process, so that deliquescence of freeze-driedfinished products such as the freeze-dried reagent balls is effectively prevented, and meanwhile the beneficial effects of being convenient to transport, redissolve and store can be achieved. The problems that in the prior art, biological agents, namely the freeze-dried preparations or freeze-dried micro-cores and freeze-dried balls are extremely prone to deliquescence and inconvenient to store and transport are solved, and meanwhile the problems that in the using process, sealing materials such as bottles and plastic packages are adopted, inconvenience is brought in use, and the cost is highare solved.

Description

technical field [0001] The invention relates to the field of freeze-dried preparations in the field of biomedicine, in particular to a freeze-dried preparation manufacturing process and a freeze-dried preparation for preventing deliquescence of freeze-dried preparation balls. Background technique [0002] Since the biological activity of biological preparations will be greatly reduced when stored at room temperature, it is relatively common to use cold chain transportation and storage in the current technology, but this method greatly increases the cost of biological pharmaceutical preparations. The lyophilized biological preparations can be stored for a long time at room temperature and still maintain good biological activity after reconstitution. However, the freeze-dried finished products of biological preparations still have their defects, that is, the freeze-dried reagents, freeze-dried microchips, and freeze-dried balls are prone to deliquescence, so sealing materials ...

AI Technical Summary

Problems solved by technology

However, the freeze-dried finished products of biological preparations still have their defects, that is, the freeze-dried reagents, freeze-dried microchips, and freeze-dried balls are prone to deliquescence, so sealing materials are used to preserve them in the prior art

However, it is very inconvenient to use sealing materials such as bottles, plastic packaging, etc., so it is an urgent requirement to design a product that can effectively prevent the deliquescence of the freeze-dried preparation and facilitate use, transportation and reconstitution.
