Description

Technical Field

[0001] This utility model belongs to the field of reagent tank technology, and specifically relates to a pipette-type reagent tank. Background Technology

[0002] Currently, the two mainstream technologies in the automated nucleic acid extraction market are fully automated nucleic acid extraction based on the magnetic rod method and fully automated nucleic acid extraction based on the aspiration method (pipette method). Because the magnetic rod method uses movable and washable magnetic rod sleeves to transfer magnetic beads, it achieves high-throughput, low-cost, and low-risk cross-contamination nucleic acid extraction, making it one of the preferred technologies for large-scale, industrialized nucleic acid extraction projects. The magnetic rod method typically employs batch simultaneous detection, where multiple test reagents are loaded into different detection wells on a deep-well plate, and then the deep-well plate is placed in the detection device for testing. However, because the corresponding device lacks a pipetting function, it cannot achieve mixing of different reagents, which greatly limits the instrument's application range.

[0003] In view of the above factors, this utility model provides a pipette reagent tray to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pipette reagent holder to solve the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved through the following technical solution: a pipetting reagent tank, including a tank body, wherein the tank body is configured as a strip structure, and the tank body includes a pipetting unit;

[0006] Each of the pipetting units includes an outlet end and an inlet end. The pipetting unit also includes a connecting tube. The connecting tube passes through the inlet end and connects the outlet end to the rubber valve storage tank. A rubber piston is provided inside the outlet end. The rubber piston can move vertically up and down inside the outlet end.

[0007] The pipetting unit also includes a rubber valve assembly, which includes a fixed rubber valve storage tank and a movable rubber valve. The rubber valve storage tank and the movable rubber valve are combined to form the rubber valve assembly.

[0008] Furthermore, the rubber valve storage groove is a hollow rectangular or circular structure, and a cavity for accommodating movable rubber valves is provided at the bottom of the rubber valve storage groove.

[0009] One end of the connecting pipe is connected to the bottom of the liquid outlet, and the other end is vertically connected to the cavity of the rubber valve storage tank.

[0010] Furthermore, the liquid outlet is a tube structure, and the liquid inlet is a rectangular cavity structure or a tube structure.

[0011] Furthermore, the lower half of the rubber valve has a horizontally penetrating circular hole, which is located directly above the connection between the connecting pipe and the rubber valve storage slot.

[0012] Furthermore, the lower half of the rubber valve storage tank has through holes connected to connecting pipes, which are connected to the liquid inlet end.

[0013] Furthermore, there is a distance between the bottom of the movable rubber valve and the bottom of the rubber valve storage slot. Pressing the movable rubber valve down to the bottom of the rubber valve storage slot allows the movable rubber valve to connect with the connecting pipe.

[0014] Furthermore, the rubber piston and the movable rubber valve are made of rubber.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention addresses the limitation of existing magnetic rod-based techniques in terms of liquid transfer capability. By using the magnetic rod of a fully automated nucleic acid extractor to press down on the movable rubber valve and piston, the liquid can be automatically moved between different wells. This significantly expands the application range of this type of instrument and saves costs without requiring additional instrument modifications. Attached Figure Description

[0026] like Figure 1-6 As shown, a pipetting reagent tank includes a tank body 1, the tank body 1 being configured as a strip structure, and the tank body 1 including at least one set of pipetting units 2;

[0027] Each of the pipetting units 2 includes an outlet end 3 and an inlet end 4. The pipetting unit also includes a connecting tube 5, which passes through the inlet end 4 to connect the outlet end 3 to the rubber valve storage tank 6. A rubber piston 7 is provided inside the outlet end 3, and the rubber piston 7 can move vertically up and down inside the outlet end 3.

[0028] The pipetting unit 2 also includes a rubber valve assembly 8, which includes a fixed rubber valve storage tank 6 and a movable rubber valve 9. The rubber valve storage tank 6 and the movable rubber valve 9 are combined to form a rubber valve assembly.

[0029] In order to facilitate the flow of liquid through the connecting pipe via the movable rubber valve 9 during use, the rubber valve storage tank 6 is a hollow rectangular structure, and a cavity 10 for accommodating the movable rubber valve 9 is provided at the bottom of the rubber valve storage tank 6.

[0030] One end of the connecting pipe 5 is connected to the bottom of the liquid outlet 3, and the other end is vertically connected to the cavity 10 of the rubber valve storage tank 6. The lower half of the movable rubber valve 9 has a horizontally penetrating circular hole 11, which is located directly above the connection between the connecting pipe 5 and the rubber valve storage tank 6.

[0031] The liquid outlet 3 is a tube structure, and the liquid inlet 4 is a rectangular cavity structure or a tube structure.

[0032] The lower half of the rubber valve storage tank 6 has through holes in the cavity 10, which are connected to the connecting pipe 5. The connecting pipe 5 is connected to the liquid inlet 4.

[0033] The aforementioned groove is a cylindrical or hollow square structure that is connected to the guide post at the lower end of the movable rubber valve 9. The guide post is a cylindrical or hollow square structure with a horizontal through hole.

[0034] There is a distance between the bottom of the movable rubber valve 9 and the bottom of the rubber valve storage groove 6. Pressing the movable rubber valve 9 down to the bottom of the rubber valve storage groove 6 can make the movable rubber valve 9 connect with the connecting pipe 5.

[0035] The aforementioned movable rubber valve 9 is embedded in the rubber valve storage groove 6. A horizontal through-hole is opened on the guide post, which is coaxially matched with the through hole opened on the groove cavity 10 to guide the liquid. The connecting pipe is a hollow pipe, one end of which is connected to the liquid outlet 3, and the other end is connected to the through hole opened on the groove cavity 10. Another through hole on the groove cavity 10 is connected to the connecting pipe, and the other end is connected to the liquid inlet 4.

[0036] The rubber piston 7 and the movable rubber valve 9 are made of rubber.

[0037] The tank 1 is equipped with a pipetting unit 2 and multiple liquid storage tanks. Each liquid storage tank has the same length or diameter, and its width and height are determined according to the amount of liquid stored. The tank 1 is used in conjunction with an external instrument support (not shown in the figure, which is the prior art).

[0038] Working principle: In actual use, the tank provides the main space for storing reagents. Pressing down the movable rubber valve connects the inlet end (inlet tank) and the outlet end (outlet tank) through the connecting pipe. Pressing down the rubber piston causes the liquid in the outlet end to enter the inlet end along the bottom connecting pipe, thus completing the movement of the liquid.
