Joint detection chip kit

Abstract

A joint detection chip kit comprises: a cover plate provided with a plurality of detection windows; a bottom plate, wherein a hollow hole is formed in a position, corresponding to the detection window, of the bottom plate; a detection film arranged between the cover plate and the bottom plate, wherein a sample point is arranged at the position opposite to an observation opening; wherein the cover plate can be pressed and fixed on the bottom plate, so that the detection films in the detection window are sealed and isolated. By adopting the structure, air at the bottom of the detection film can be exhausted by arranging the hollowed-out holes in the corresponding positions of the bottom plate and the detection window, so that hollowing of the reaction film after the cover plate is pressed and fixed on the bottom plate is prevented.

Description

technical field [0001] The invention relates to the technical field of kits, in particular to a joint detection chip kit. Background technique [0002] In the detection of food safety small molecules and animal disease detection, the joint detection chip kit is usually used to detect samples. The samples that need to be detected in this type of detection are generally very large, so it is usually necessary to detect multiple samples on the same detection membrane. In order to prevent mixing and contamination between samples, the detection membrane is usually arranged on the bottom plate, and is pressed and fixed on the bottom plate by a cover plate with multiple detection windows, so that the detection window is pressed against the reaction membrane and the reaction membrane is in close contact, thereby preventing Samples within the detection window flow out into other detection windows. However, since the material of the reaction film is usually relatively soft, when the ...

AI Technical Summary

Problems solved by technology

However, because the material of the reaction film is usually relatively soft, when the detection window presses the reaction film, if there is air between the reaction film and the bottom plate, the reaction film in the detection window at the middle position will be hollow.

This kind of hollowing will not only affect the contact between the sample and the sample point on the reaction membrane, but also cause liquid leakage, resulting in cross-contamination of samples in different detection windows, thus affecting the detection results
