Problems solved by technology

[0003] However, due to the low viscosity of the placed liquid, it will shake during the pushing process. The shaking will easily lead to fluidity of the placed liquid, which will contact the inner side of the closed and sealed cover, causing mutual cross-infection, thus making the test result accurate. reduced

Embodiment 1

[0026] like Figure 1-Figure 5 Shown:

[0027] The present invention is a biological detection cassette, which comprises a control switch 1, a detection mechanism 2, and a detection box 3. The control switch 1 is embedded on the surface of the detection box 3, and the detection mechanism 2 is installed inside the detection box 3. The detection mechanism 2 is provided with a closing cover 21, a placement structure 22, a sliding plate 23, and a sliding track 24. The closing cover 21 is embedded on the upper end of the sliding plate 23, and the sliding track 24 is engaged on the side of the sliding plate 23. The placement structure 22 is fitted inside the upper end of the sliding plate 23, the sliding track 24 is installed inside the detection box 3, and the lower end of the closing cover 21 is provided with a layer of rubber material, which is bonded to the upper end of the sliding plate 23, which has a sealing effect and prevents External air enters the placement structure 22 ...

Embodiment 2

[0034] like Figure 6-Figure 8 Shown:

[0035] Wherein, the floating structure 223 is provided with an opening and closing structure w1, a drainage plate w2, and a floating block w3, the opening and closing structure w1 is embedded on the left and right sides of the floating block w3, and the drainage plate w2 is engaged on the upper end of the floating block w3 , the floating block w3 is installed on the inner upper end of the detection box 222, the drainage plate w2 has a triangular structure, and its interior is in a sealed state, and the floating block w3 is made of foam material, which has the characteristics of high buoyancy, so that the biological detection liquid can pass through the drainage The plate w2 is guided into the opening and closing structure w1, and at the same time, under the buoyancy of the slider w3, the floating structure 223 is integrally attached to the surface of the biological detection liquid.

[0036] Wherein, the opening and closing structure w1 i...

Abstract

The invention discloses a biological detection cartridge which structurally comprises a control switch, a detection mechanism and a detection box, the control switch is fixedly embedded in the surface of the detection box, the detection mechanism is installed in the detection box, swing generated in the liquid moving process is blocked in a blocking structure, meanwhile a floating structure is attached to the surface of biological liquid, and the swinging biological detection liquid is blocked; meanwhile, the liquid can flow to the lower end of a bending plate from a guide plate, so that the biological detection liquid is blocked, the situation that the swinging amplitude of the biological liquid is too large after the biological liquid is shaken is avoided, the biological detection liquid is guided by a drainage plate to enter an opening and closing structure; meanwhile, the floating structure is integrally attached to the surface of the biological detection liquid under the buoyancy action of the floating block, so that the biological detection liquid circulates on a drainage structure, pressure is generated on a spring, the biological detection liquid flows down from a blocking plate, the blocking plate blocks the liquid level of the biological detection liquid, and the swinging amplitude of the biological detection liquid is reduced.

Description

technical field [0001] The invention relates to the technical field of rapid biological detection, in particular to a biological detection cassette. Background technique [0002] The biological detection cassette has the effect of rapid detection. The detection liquid drips on the surface of the detection plate of the cassette, thereby pushing the detection plate and closing the opening for electronic detection. At the same time, the detection liquid needs to be diluted to a certain extent to form a concentration gradient, which is convenient for detection. analysis comparison. [0003] However, due to the low viscosity of the placed liquid, it will shake during the pushing process. The shaking will easily lead to fluidity of the placed liquid, which will contact the inner side of the closed and sealed cover, causing mutual cross-infection, thus making the test result accurate. degree reduced. Contents of the invention [0004] The present invention is realized through t...
