[0002] A reagent bottle is a bottle used to hold chemical reagents. It can be divided into glass and plastic according to the material, and can be divided into a wide-mouth bottle and a narrow-mouth bottle according to the size. Na0H is usually stored in a reagent bottle, and the storage requirements include the following points: Sodium hydroxide should be stored in a cool, dry and well-ventilated warehouse, away from fire and heat sources. The temperature in the warehouse should be controlled below 35°C, and the relative humidity should not exceed 80%; the packaging for storing sodium hydroxide must be sealed to prevent moisture absorption. Usually, plastic bottles and rubber stopper caps are used for storage, and glass bottles and glass stoppers are avoided because sodium hydroxide will react with silicon dioxide in the glass, resulting in the adhesion of the bottle stopper; therefore, it is particularly important to remove water and carbon dioxide in the reagent bottle. In the prior art, the removal structure is relatively complex and inconvenient for storage and use. Content of the Utility Model

[0019] Embodiment 1

[0020] As Figure 1 and Figure 2As shown in the figure, a water and carbon dioxide removal device for a NaOH reagent bottle is provided in a specific embodiment of the present utility model. This device is used to efficiently remove water and carbon dioxide in the NaOH reagent bottle; it specifically includes a connection cover 100 and an adsorption tube 200; a connection tube 300 connected to the adsorption tube 200 is provided at the upper end of the connection cover 100; an adsorption cavity that communicates with each other is provided in the adsorption tube 200, and a water-absorbing resin 500 and soda lime particles 600 are respectively filled in the two adsorption cavities. The two adsorption cavities are separated by a first isolation sheet 700. A second isolation sheet 800 is provided on the inner side of the end of the adsorption tube 200 connected to the connection tube 300. The first isolation sheet 700 is arranged in a separated manner and the second isolation sheet 800 is arranged in a hollowed-out manner.

[0021] Through the above settings, the device provided in this embodiment can remove water and carbon dioxide in the NaOH reagent bottle. When in use, it is connected to the reagent bottle through the connection cover 100, so that the adsorption tube 200 communicates with the inside of the reagent bottle through the connection tube 300. The water and carbon dioxide in the reagent bottle can be fully removed by the water-absorbing resin 500 and soda lime particles 600 in the adsorption tube 200. The overall structure is simple and reasonable, and it is convenient to use; since isolation sheets are provided in the adsorption tube 200, the water-absorbing resin 500 and soda lime particles 600 can be separated from each other to avoid mixing; at the same time, it can also prevent the water-absorbing resin 500 and soda lime particles 600 from entering the connection tube 300 and causing blockage. In practical applications, the connection tube 300 and the glass tube can be made of glass material to make them in a transparent structure, which is convenient to observe the adsorption effect.

[0022] As mentioned above, the connection cover 100 needs to be connected to the reagent bottle containing NaOH. To ensure the connection tightness and the convenience of disassembly and assembly, in this embodiment, multiple sealing rings 900 are provided on the inner wall of the opening of the connection cover 100, and multiple anti-slip protrusions are provided on the outer periphery of the connection cover 100. In this way, after the connection cover 100 is connected to the reagent bottle, the connection tightness is ensured through the sealing rings 900, and the anti-slip protrusions are provided to facilitate the rotation of the connection cover 100. In addition, in this embodiment, pipe connectors 1000 are also provided at the upper end of the connection cover 100 and the end of the adsorption tube 200, and both ends of the connection tube 300 are hermetically connected to the pipe connectors 1000. The end of the connection tube 300 can be hermetically connected to the connection cover 100 and the adsorption tube 200 through the pipe connectors 1000, and a sealing ring 900 structure can be provided on the pipe connectors 1000 to ensure the connection sealing effect.

[0023] After long-term use, the water-absorbing resin 500 and soda lime particles 600 in the adsorption tube 200 become ineffective due to adsorbing water and carbon dioxide and need to be taken out for replacement. In this embodiment, a replacement port is provided at the end of the adsorption tube 200, and a detachable sealing cover 1100 is installed at the replacement port. In this way, after the sealing cover 1100 is removed, the replacement port can be opened, which is convenient to take out the internal water-absorbing resin 500 and soda lime particles 600. Medical staff can use tweezers and other tools to perform the replacement operation, improving the convenience.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
