Technical Field

The utility model relates to a kit that uses when adding reagent.

Background

The kit is a test device commonly used in laboratories and is used for storing various liquid reagents used in some tests. When a tester needs to remove a reagent from a reagent kit, it is a common practice that the tester opens a lid of the reagent kit, and then uses a syringe or a dropper to aspirate a certain amount of the reagent, which is then used in a test operation. Because this process requires manual operations, it is also prone to contamination on the hands, body or test equipment if the test personnel are unskilled or careless. The consequences can be severe if the reagents used are corrosive or toxic to some extent. Although some reagent boxes for adding reagents are available in the market, the reagent boxes simply press the reagents out by using air pressure, and an air inlet and a reagent storage tank are basically in a direct blowing mode, so that the adding amount of the reagents is unstable due to uneven air inlet, and the reagent also flows back from the air inlet due to improper operation.

1 and 2, the utility model comprises a box body 15, an air inlet 1 arranged on the side surface of the box body 15, a liquid storage tank 8 communicated with the air inlet 1 through a long and thin flow passage and a liquid outlet 14 communicated with the liquid storage tank 8. The reservoir 8 is located inside the case body 15, and the liquid outlet 14 is installed on the side of the case body 15 and located at the bottom of the reservoir 8.

The elongated flow channel comprises a first flow channel 11 positioned at the lower part of the box body 15 and a second flow channel 5 arranged at the upper part of the box body 15 and communicated with the first flow channel 11, one end of the first flow channel 11 is communicated with the air inlet 1, and one end of the second flow channel 5 is communicated with the liquid storage tank 8. The first flow channel 11 and the second flow channel 5 are both in a continuous S-shaped design, so that the conveying time of the gas in the flow channels can be further prolonged, and sufficient time is provided for uniformly mixing the gas and conveying the gas into the liquid storage tank 8.

Seen from the flowing direction of gas in the box, an air inlet bin 2 communicated with an air inlet 1 is arranged in a box body 15, an air storage bin 16 communicated with the air inlet bin 2 is arranged below the air inlet bin 2, a fourth air storage partition bin 10 communicated with the air storage bin 16 is arranged on one side of the air storage bin 16, the fourth air storage partition bin 10 is communicated with one end of a first flow channel 11, a first air storage partition bin 12 and a second air storage partition bin 13 are sequentially communicated with the other end of the first flow channel 11, one side, far away from the first air storage partition bin 12, of the second air storage partition bin 13 is communicated with a third air storage partition bin 17 through a first air hole 4, one end of a second flow channel 5 is communicated with the third air storage partition bin 17, the other end of the second air storage bin is communicated with an overflow groove 6, and the overflow groove 6 is communicated with a liquid storage tank. The first flow channel 11, the second flow channel 5 and the third flow channel 7 are of a continuous S-shaped design. Through the design of a series of S-shaped flow channels and a plurality of gas storage separation bins and overflow grooves, the time of gas entering the liquid storage tank 8 from the gas inlet 1 can be greatly prolonged, so that the entering gas can be fully mixed in the structures, and even if the gas entering from the gas inlet 1 is uneven, the gas can be fully and uniformly mixed when entering the liquid storage tank 8 after being conveyed for a long time through the structures.

The second flow channel 6 and the communication part of the third flow channel 7 and the overflow groove 6 are both positioned at the top of the overflow groove 6, when the reagent in the liquid storage groove 8 flows back, the reagent flows into the overflow groove 6 firstly, and only after the overflow groove 6 is filled, the reagent continues to enter the second flow channel 5.
