Description

Technical Field

[0001] This utility model relates to the field of in vitro diagnostic technology, specifically to a reagent bottle. Background Technology

[0002] In vitro diagnostic instruments require the continuous use of large quantities of reagents when analyzing samples. Existing reagent bottles typically contain reagents for multiple samples. During use, a tip or needle must be repeatedly inserted into the bottle to draw reagents, which are then added to different samples for testing. When the tip or needle is repeatedly inserted into the bottle, friction between the tip / needle and the bottle opening poses a risk of lifting the bottle. Furthermore, prolonged exposure of the bottle to air after opening can cause some reagents to evaporate, leading to changes in reagent composition and potentially causing abnormal deviations in the measured values. Summary of the Invention

[0003] This utility model discloses a reagent bottle to solve the problem in the prior art that reagent bottles are easily lifted by a tip or reagent needle.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A reagent bottle includes a bottle body and a cap disposed on the bottle body; a first magnetic material is disposed inside the bottle body; a second magnetic material is disposed at a placement position adapted to the bottle body; the first magnetic material and the second magnetic material attract each other to generate an attractive force.

[0005] Furthermore, the first magnetic material is a circular iron sheet, and the second magnetic material adapted to the circular iron sheet is a magnet.

[0006] Furthermore, the first magnetic material is a magnet, and the second magnetic material adapted to the magnet is a circular iron sheet.

[0007] Furthermore, the bottle body includes a receiving portion; and a bottle holder that is interference-connected to the receiving portion; the first magnetic material is disposed between the receiving portion and the bottle holder.

[0008] Furthermore, the bottom of the accommodating part has a frustum-shaped structure.

[0009] Furthermore, a silicone sheet and a PE film are disposed between the bottle body and the bottle cap; the silicone sheet is disposed above the PE film; and the PE film is disposed at the bottle opening.

[0010] Furthermore, the silicone sheet is provided with a cross-shaped seal. This utility model adopts the above technical solution and has the following advantages: This invention provides a first magnetic material and a second magnetic material that can attract each other inside the bottle and at the placement position. Due to the attraction of the second magnetic material at the placement position to the reagent bottle, the reagent bottle can be prevented from being lifted by the tip or reagent needle when the reagent is drawn.

Detailed Implementation The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] like Figure 1 , Figure 2 As shown, a reagent bottle includes a bottle body and a bottle cap 1 disposed on the bottle body; a first magnetic material 2 is disposed inside the bottle body; a second magnetic material 4 is disposed in a placement position 3 adapted to the bottle body; the first magnetic material 2 and the second magnetic material 4 attract each other to generate an attractive force.

[0014] This invention provides a first magnetic material 2 and a second magnetic material 4 that can attract each other inside the bottle and at the placement position 3. Due to the attraction of the second magnetic material 4 at the placement position to the reagent bottle, the reagent bottle can be prevented from being lifted by the tip or reagent needle when the reagent is drawn.

[0015] Furthermore, the first magnetic material 2 is a circular iron sheet, and the second magnetic material 4 adapted to the circular iron sheet is a magnet; or the first magnetic material 2 is a magnet, and the second magnetic material 4 adapted to the magnet is a circular iron sheet. It is understood that the magnetic materials inside the bottle and in the placement area can also be other mutually compatible magnetic materials capable of generating an attractive force.

[0016] The bottle body includes a receiving portion 5 and a bottle holder 6 that is interference-fitted to the receiving portion 5; a first magnetic material 2 is disposed between the receiving portion 5 and the bottle holder 6. The receiving portion 5 of this invention is used for storing test reagents.

[0017] This invention facilitates the installation and disassembly of the accommodating part 5 and the bottle holder 6 through an interference fit; thus facilitating the installation of magnetic materials inside the bottle.

[0018] Furthermore, the bottom of the container 5 has a frustum-shaped structure. When the amount of reagent in the reagent bottle is small, the frustum-shaped structure facilitates the collection of reagent in the bottle, thus making it easier for the tip or reagent needle to draw it up.

[0019] Furthermore, a silicone sheet 7 and a PE film 8 are provided between the bottle body and the bottle cap 1; the silicone sheet 7 is positioned above the PE film 8; the PE film 8 is positioned at the bottle opening.

[0020] It is understood that the silicone sheet 7 of this utility model can be stuck inside the bottle cap 1 to prevent the silicone sheet 7 from being pulled out of the bottle cap 1 by the tip or reagent needle; the bottle cap 1 is provided with a through hole to facilitate the tip or reagent needle to be inserted into the receiving part 5 through the through hole; the diameter of the silicone sheet 7 and the PE film 8 is larger than the inner diameter of the bottle mouth to prevent the silicone sheet 7 and the PE film 8 from falling into the bottle body.

[0021] Furthermore, a cross-shaped seal is provided on the silicone sheet 7.

[0022] This invention, by adding a silicone sheet 7 and a PE film 8 to the bottle opening, allows the seal to be opened during use. After use, the silicone sheet 7 automatically resets to achieve a sealing effect, isolating air. This invention optimizes the existing reagent bottle structure, realizing the functions of opening-free, puncture extraction, and automatic sealing. It simplifies the operation steps, reduces the volatilization of the reagent solution, extends the usage time, and avoids the risk of component changes caused by long-term exposure to open bottles.
