Embodiment 1

[0031] Figure 1-2 The basic structural diagram of the liquid detection system of the embodiment of the present invention is schematically given, as Figure 1-2 As shown, the liquid detection system includes:

[0032] A frame, which is used to carry components such as chips and guide rails;

[0033] A carrier, the carrier is arranged on the frame and is suitable for carrying the chip; for example, the bottom end of the carrier is two V-shaped detection grooves, which are suitable for the two V-shaped detection cavities of the chip insertion and fixation;

[0034] A fixed plate 41, the fixed plate 41 has a first through hole and a third through hole, and is arranged on the guide rail 43 through a slider 42; when the fixed plate 41 is in the working position, from top to bottom, the first The three-way hole corresponds up and down with the first groove (first mating part) of the linkage part 21 of the chip on the carrier (the safety pin has been pulled out);

Embodiment 2

[0081] An application example of the liquid detection system with an automatic fastening chip according to Embodiment 1 of the present invention in fluorescent quantitative PCR.

[0082] In this application example, if Figure 1-2 As shown, the liquid detection system includes:

[0083] A chip, which includes a cover 11, a housing, a first base and a second base arranged from top to bottom;

[0084] A casing, the casing has a cylindrical passage, and a plurality of liquid chambers are arranged around the cylindrical passage, respectively for accommodating samples and reagents, and the bottom of the liquid chamber has concentric circles distributed along the central axis of the cylindrical passage. Each outlet has a film that closes the liquid cavity; the closure that the housing has seals a plurality of liquid cavities from the upper part, and the closure has a through hole that communicates with the interior of the liquid cavity and is suitable for adding samples, etc.;

Embodiment 3

[0135] According to the application example of the liquid detection system in embodiment 1 of the present invention in fluorescent quantitative PCR, the difference from embodiment 2 is:

[0136] 1. The openings at the bottom of each liquid chamber are distributed in non-concentric circles, and the openings of the first group are also distributed in non-concentric circles.

[0137] 2. An annular groove is provided on the periphery of the sixth through hole, and the sealing element is located in the annular groove and is set outside the rotating element.

[0138] 3. The end of the horizontal part of the safety pin away from the end inserted into the first groove also has a vertical part. When the safety pin is inserted into the second groove, the vertical part is exposed, which is convenient for the operator to hold and pull out.

[0139] 4. The first switching module adopts a combination of multiple reflectors to combine the excitation lights with different wavelengths output b...

Abstract

The invention provides a liquid detection system with an automatic chip buckling function. The liquid detection system comprises a chip and a frame. The chip comprises a shell, a cover body, a first base and a multi-channel direction selecting valve; a linkage part of the multi-channel direction selecting valve penetrates through the first base and the shell, and a first matching part is arrangedat an upper end; the liquid detection system further comprises a bearing piece arranged on a frame and suitable for bearing a chip; a fixed plate is provided with a first through hole and is arrangedon a guide rail through a sliding piece; the guide rail is horizontally arranged on the frame; a first motor is fixed on the fixed plate; a connecting unit penetrates through the first through hole ofthe fixed plate and is connected with a moving part, and the first motor drives the connecting unit to move downwards; and the moving part is arranged on the lower side of the fixed plate and the upper side of the cover body. The system has advantages of a simple structure, automation and the like.

Description

technical field [0001] The invention relates to liquid detection, in particular to a liquid detection system with the function of automatically fastening chips. Background technique [0002] In various analyses, samples and various reagents need to be added to mixing chambers, such as test tubes, respectively. These samples can be human and animal samples, such as whole blood, plasma, serum, urine, saliva, feces, cerebrospinal fluid or lavage fluid, wax-sealed tissue and slices, tissue homogenate, and plants, including traditional Chinese medicine, food Raw materials, processed food, meat, beverages and wines, and raw materials and semi-finished products in the beverage manufacturing process can also be cell culture fluid or bacteria and virus culture fluid. The types of components analyzed include minerals, inorganic substances, organic substances, nucleic acid DNA, RNA, protein or fat. Currently, common liquid detection systems are: [0003] The chip has a liquid select...
