Description

Technical Field

[0001] This invention belongs to the field of biological sample detection technology, specifically relating to a lysis cell. Background Technology

[0002] The nucleic acid extraction process involves several steps, including cell lysis, nucleic acid adsorption and purification, and nucleic acid elution and collection. For the vast majority of nucleic acid testing samples, these steps are completed under liquid reaction conditions.

[0003] For example, cell lysis usually takes place in a cavity containing reagents. The liquid and reagents are mixed to achieve cell lysis. However, the existing lysis cell structure is simple and only used to contain reagents and liquids. The liquid and reagents are not mixed evenly in the lysis cell, which degrades the lysis performance of the lysis cell. Utility Model Content

[0004] This invention provides a pyrolysis cell, which aims to solve the problem that existing pyrolysis cells cannot mix liquids and reagents, resulting in poor pyrolysis performance.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A pyrolysis pool includes a first flexible wall and a second flexible wall, with a sealed pyrolysis cavity formed between the first flexible wall and the second flexible wall;

[0007] The pyrolysis tank further includes an inlet and an outlet, both of which are connected to the pyrolysis chamber;

[0008] The pyrolysis tank is provided with a guide section to guide the liquid entering through the inlet, and the guide section causes the liquid entering through the inlet to circulate around the guide section.

[0009] A further improved solution: the liquid inlet is located between the guide and the liquid outlet.

[0010] Based on the above technical solution: the liquid inlet is located between the guide and the liquid outlet. The liquid entering through the liquid inlet circulates around the guide. The liquid entering through the liquid inlet has a better mixing effect with the reagents pre-stored in the pyrolysis chamber, thereby making the pyrolysis cell have a better pyrolysis effect.

[0011] A further improvement: the liquid inlet direction is perpendicular to the liquid outlet direction.

[0012] Based on the above technical solution: the liquid inlet direction is perpendicular to the liquid outlet direction, and the liquid inlet direction is perpendicular to the liquid outlet direction, which makes the arrangement of the pyrolysis chamber more flexible and the arrangement of other chambers connected to the pyrolysis chamber easier.

[0013] A further improved solution: The guide portion is elongated, and the guide portion is formed by heat sealing a portion of the first flexible wall and a portion of the second flexible wall.

[0014] Based on the above technical solution: the guide part is elongated, and the guide channel formed between the guide part and the side wall of the lysis chamber has a longer length, which is more conducive to guiding the liquid.

[0015] A further improved solution: the guide portion is arranged along the liquid inlet direction along the length direction of the liquid inlet.

[0016] Based on the above technical solution: the length direction of the guide part is set along the liquid inlet direction of the liquid inlet, so that the liquid entering through the liquid inlet can be better guided by the guide part, making it easier for the liquid entering through the liquid inlet to mix with the reagent, and further optimizing the pyrolysis effect of the pyrolysis cell.

[0017] A further improvement: the two ends of the guide are respectively provided with rounded corners to facilitate the passage of liquid.

[0018] Based on the above technical solution: both ends of the guide are respectively provided with rounded corners to facilitate the passage of liquid. The rounded corners can prevent liquid or reagent from being stuck at the sharp part of the guide, making it easier for liquid and reagent to flow in the lysis chamber, and the liquid in the lysis chamber can be completely discharged.

[0019] A further improved solution: the cross-sectional shape of the pyrolysis pool is rectangular, and the pyrolysis pool is provided with a notch to reduce the space occupied by the pyrolysis pool.

[0020] Based on the above technical solution: the cross-sectional shape of the pyrolysis pool is rectangular, and the pyrolysis pool is provided with a notch to reduce the space occupied by the pyrolysis pool. The notch makes it easier to arrange other structures connected to the pyrolysis pool and reduces the space occupied by the pyrolysis pool.

[0021] A further improved solution: the first flexible wall and the second flexible wall are heat-sealed together.

[0022] Based on the above technical solution: the second flexible wall is heat-sealed together with the first flexible wall, so that the connection strength between the first flexible wall and the second flexible wall is higher, thereby making the pyrolysis cavity less prone to leakage.

[0023] A further improved solution: The first flexible wall and the second flexible wall form the pyrolysis cavity through four heat-sealing strips connected end to end.

[0024] Based on the above technical solution: the first flexible wall and the second flexible wall form the pyrolysis cavity through four heat-sealing strips connected end to end. The pyrolysis cavity has good sealing performance and is not easy to leak.

[0025] A further improved solution: the first flexible wall and the second flexible wall are an integral structure, and the first flexible wall and the second flexible wall are connected by three heat-sealing strips to form the pyrolysis cavity.

[0026] Based on the above technical solution: the first flexible wall and the second flexible wall are an integral structure, and the first flexible wall and the second flexible wall form the pyrolysis chamber through three heat sealing strips. The pyrolysis pool is easy to process, which reduces the manufacturing cost of the pyrolysis pool.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention utilizes a first flexible wall and a second flexible wall to form a sealed pyrolysis chamber. A guide portion is provided within the pyrolysis chamber, causing the liquid entering through the inlet to circulate around it. The liquid entering the pyrolysis chamber mixes evenly with the pre-stored reagents within the chamber. Furthermore, the liquid has a longer flow path within the pyrolysis chamber, resulting in more uniform mixing of the liquid and reagents, thereby optimizing the pyrolysis effect of the pyrolysis cell.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by users of the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] refer to Figures 1 to 4 A pyrolysis pool includes a first flexible wall 1 and a second flexible wall 2, wherein a sealed pyrolysis cavity 3 is formed between the first flexible wall 1 and the second flexible wall 2;

[0038] The pyrolysis tank also includes an inlet 4 and an outlet 5, both of which are connected to the pyrolysis chamber 3;

[0039] The pyrolysis tank is provided with a guide section 6 to guide the liquid entering the inlet 4, and the guide section 6 causes the liquid entering the inlet 4 to circulate around the guide section 6.

[0040] Both the first flexible wall 1 and the second flexible wall 2 are made of thin film. The first flexible wall 1 and the second flexible wall 2 can be transparent or opaque.

[0041] Specifically: the liquid inlet 4 is located between the guide part 6 and the liquid outlet 5.

[0042] The liquid inlet 4 is perpendicular to the liquid outlet 5.

[0043] For example, the inlet 4 can be set horizontally, and the outlet 5 can be set perpendicular to the inlet 4 on the horizontal plane.

[0044] The guide portion 6 is elongated. The guide portion 6 is formed by heat sealing a portion of the first flexible wall 1 and a portion of the second flexible wall 2.

[0045] The guide portion 6 is arranged along the liquid inlet 4 in the direction of liquid inlet along its length.

[0046] The guide portion 6 has rounded corners at both ends to facilitate the passage of liquid.

[0047] In other words, the cross-sectional shape of the guide portion 6 is a rounded rectangle. The cross-sectional shape of the guide portion 6 can also be other shapes.

[0048] Specifically, there can be one guide section 6 or multiple guide sections 6. The exact number of guide sections 6 is not limited and can be reasonably determined according to needs.

[0049] refer to Figure 1 Wherein: the cross-sectional shape of the pyrolysis pool is rectangular, and the pyrolysis pool is provided with a notch 7 to reduce the space occupied by the pyrolysis pool.

[0050] Wherein: the first flexible wall 1 and the second flexible wall 2 are heat-sealed together.

[0051] refer to Figure 3 Option 1: The first flexible wall 1 and the second flexible wall 2 are connected by four heat-sealing strips to form the pyrolysis cavity 3.

[0052] refer to Figure 4 Option 2: The first flexible wall 1 and the second flexible wall 2 are an integral structure, and the first flexible wall 1 and the second flexible wall 2 form the pyrolysis cavity 3 through three heat sealing strips.

[0053] When the first flexible wall 1 and the second flexible wall 2 are an integral structure, there is a folded edge between the second flexible wall 2 and the first flexible wall 1. The folded edge forms a sealing edge, and the edge opposite to the folded edge forms a first heat-sealing edge. The sealing edge and the first heat-sealing edge are connected by a second heat-sealing edge and a third heat-sealing edge to form a sealed pyrolysis cavity 3.

[0054] The heat sealing process is a common process in existing technology. The liquid inlet 4 and the liquid outlet 5 are directly formed by the heat sealing process, that is, no heat sealing is performed at the liquid inlet 4 and the liquid outlet 5.

[0055] The working principle of this embodiment:

[0056] Reagents can be pre-stored in the lysis chamber 3. Then, liquid is introduced into the lysis chamber 3 through the inlet 4. At this time, the outlet 5 is closed. Liquid continuously enters the lysis chamber 3. Under the guidance of the guide 6, the liquid entering the lysis chamber 3 circulates around the guide 6, so that the liquid and reagent are mixed evenly, which is conducive to cell lysis. After lysis is completed, it is discharged from the outlet 5.

[0057] The pyrolyzed liquid is discharged from outlet 5. At this time, when the liquid is discharged from outlet 5, inlet 4 can be closed.

[0058] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
