Test paper box for storing test paper and sample detection device

Abstract

The invention provides a detection device for biological sample detection. The detection device comprises a first cover plate, a second cover plate and detection test paper; the first cover plate comprises a quantity-controlled sample adding channel; the quantity-controlled sample adding channel is provided with a sample adding hole and a liquid outlet; the volume of the quantity-controlled sample adding channel is at least the minimum liquid dosage required by detection; the quantity-controlled sample adding channel has a capillary effect, so that when the quantity of sucked liquid cannot reach the minimum detection dosage, the liquid cannot be absorbed by the detection test paper, or when the sample quantity is not enough, the liquid sample cannot be in contact with the detection test paper quickly; and when the amount of sucked liquid reaches the minimum detection dosage, the sucked liquid sample fills the sample adding channel between the sample adding hole and the liquid outlet, so that the liquid sample at the liquid outlet can be in contact with the detection test paper. The detection device can realize automatic quantitative sample adding and can be applied to the detection fields of physiological index detection, environment detection and the like; and a lateral cross flow detection method or a vertical flow detection method can realize detection in the detection device.

Description

[0001] This application is a divisional application of Chinese patent application 201610543841.6 (application date July 8, 2016). technical field [0002] The invention relates to a detection device for measuring clinical physiological indexes, especially a detection device for rapidly measuring biochemical indexes. Background technique [0003] The analysis of samples can generally be divided into two categories of techniques, namely dry chemical analysis techniques and wet chemical analysis techniques. Dry chemical analysis technology is relative to wet chemical technology. It refers to adding liquid detection samples directly to dry test paper strips (dry test paper strips), and using the moisture of the tested sample as a solvent to cause specific chemical reactions. , so as to carry out the method of chemical analysis. Test strips used in dry chemical analysis techniques generally use lateral-flow or vertical-flow methods for detection. The structure of the dry test s...

Problems solved by technology

However, the disadvantage of this design is that when the amount of sample added does not reach the amount required for detection, the sample will still touch the test paper and enter the test paper, and the inspector will also get a result

Due to insufficient sample volume, the test results are not accurate

Since this type of test kit does not give a hint that the amount of sample added is insufficient, the inspector cannot know

This is not only a waste of test strips, but more seriously, it may lead to wrong diagnostic conclusions
