Problems solved by technology

[0003] Similarly, there is no good product for storage based on the above-mentioned lyophilized preparations. Therefore, it is also necessary to design a lyophilized reagent preparation box that is easy to reconstitute, has a risk of contamination during the operation, and is easy to store, produce, and transport. become an urgent requirement

Embodiment Construction

[0094] In order to make the technical solutions and beneficial effects of the present invention clearer, the implementation manners of the present invention will be further explained in detail below.

[0095] In order to clearly express and understand the content of the present invention, the present invention is divided into two parts related to the production process of the freeze-dried preparation and the freeze-dried preparation box.

[0096] The first part: about the production process of the freeze-dried preparation and a kind of freeze-dried preparation made.

[0097] The basic principle of freeze-drying is based on the three-state change of water. water (H 2 O) There are three phases, namely solid state, liquid state and gaseous state, and the three phase states can be converted to each other and can coexist.

[0098] Freeze drying uses refrigerant to indirectly reduce the temperature of air containing water vapor, and removes moisture in the air by means of water va...

Abstract

The invention relates to the technical field of freeze-drying of biological reagents, in particular to aFreeze-dried preparation production process. A pipettor tip is used as a carrier of the Freeze-dried preparation. The pipettor suction head sucks the stock solution and then directly carries out cryopreservation in the pipettor suction head to generate a freeze-dried reagent, and then packagingis carried out. When in use, the pipette is directly connected. The invention also discloses aFreeze-dried reagent preparation box based on the pipettor sucker as a carrier of a lyophilized preparation. The Freeze-dried reagent preparation box comprises a shell, the pipettor sucker and a reconstitution fluid carrier. The shell is provided with a cavity with an open upper part; a freeze-dried reagent is placed at the bottom of the pipettor sucker; the reconstitution fluid carrier is provided with a liquid tank, a liquid tank film is arranged at the upper part of the liquid tank, and a reconstitution fluid is stored in the reconstitution fluid carrier; the pipettor sucker is positioned at the upper part of the reconstitution fluid carrier, and the tip faces the liquid tank film; and a sealing piece is arranged at the upper opening of the cavity of the shell. The invention is convenient for storage and transportation of freeze-dried reagents, is convenient for redissolving of the freeze-dried reagents, and avoids pollution in the redissolving process.

Description

technical field [0001] The invention relates to the technical field of freeze-drying of biological materials, in particular to a production process of a freeze-dried preparation, a freeze-dried reagent, and a freeze-dried reagent preparation box. Background technique [0002] Because biological agents can well maintain their biological activity in a freeze-dried state, freeze-dried preparations of reagents are widely used. However, in the application process of the freeze-dried reagent, it is necessary to reconstitute the freeze-dried reagent, that is, divide the freeze-dried reagent into containers, then add the reconstitution solution, and then use a pipette gun to take out the reconstituted freeze-dried reagent for application. In this process, not only the process is cumbersome, but also the contamination of biological agents is very likely to occur when the environmental conditions are not standard, thereby reducing the accuracy of the test results. Therefore, it becom...
