Problems solved by technology
Most biological reagents are packaged by filling. Biological reagents are highly sensitive reagents and are easily oxidized by air.
The existing biological reagent filling equipment does not perform anaerobic filling or the vacuum degree is not enough during filling. The air is combined with the reagent during filling, which affects the life of the reagent, resulting in a short shelf life of the reagent, which is prone to failure and affects the test results.

Embodiment Construction
[0058] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.
[0059] figure 1 and figure 2 It is a structural diagram of reagent filling equipment in an anaerobic environment proposed by the present invention. The device of the present application can inject reagents into reagent bottles 33 and fill reagents from reagent bottles 33 to reagent bags 36 in an anaerobic environment. , so as to ensure the complete isolation of the reagent from the air and prevent the reagent from being oxidized. The device of this application is especially suitable for biological reagents. Due to the high sensitivity of biological reagents and the way of filling is usually used, the use of the device of this application can greatly extend the shelf life of biological reagents and effecti...

The invention discloses a reagent filling equipment and a filling method thereof in an oxygen-free environment, which include a vacuum pump, a plunger pump, a reagent bottle, a reagent bag, etc., and are loaded with a first control valve connected to the four by pipelines, The second control valve, the third control valve, the fourth control valve, etc. constitute all kinds of required pipelines, and the inert gas can be filled into the reagent bottle by means of a vacuum pump and an external inert gas source before injecting the reagent into the reagent bottle. Reagent bottle, and after injecting the reagent into the reagent bottle, the oxygen dissolved in the reagent can also be separated out by inert gas replacement in the same way, and the inert gas can be replaced by the air in the reagent bag before the reagent is delivered to the reagent bag. The plunger pump passes the reagent from the reagent bottle into the reagent bag in an oxygen-free environment. The present application realizes the work of continuously filling the reagent bags in an anaerobic environment with only one vacuum pump and plunger pump through various loading pipelines.
Description
technical field [0001] The invention relates to the technical field of liquid filling, in particular to reagent filling equipment and a filling method thereof in an oxygen-free environment. Background technique [0002] With the continuous development of medical technology, biological reagents are widely used in in vitro diagnosis. Most biological reagents are packaged by filling. Biological reagents are highly sensitive reagents and are easily oxidized by air. The existing biological reagent filling equipment does not perform anaerobic filling or the vacuum degree is not enough during filling. The air combines with the reagent during filling, which affects the life of the reagent, resulting in a short shelf life of the reagent, which is prone to failure and affects the test results. Therefore, it is very necessary to design a filling device in an oxygen-free environment. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the ...
