Sample detection apparatus

Abstract

The present invention relates to a sample detection apparatus, which comprises a collection chamber for collecting samples and a test element for detecting the sample, wherein the collection chamber and the test element form a fluid communication, and the apparatus further comprises a draining element for making the sample in the collection chamber do not directly flow into the test element. With the sample detection apparatus, the condition that the corresponding detection can not be performed timely due to direct diffusion of the sample out from the test element so as to cause the not significant or invalid detection result can be prevented, and the requirement of the collection amount on the sample is broadened, such that the application range of the detection apparatus is wide.

Description

technical field [0001] The invention relates to a sample detection device, in particular to a cavity of the sample detection device with both collection and detection functions. Background technique [0002] Illegal drug abuse is a well-recognized and worsening social problem in our society. In 2003, the US Department of Health and Human Services found that about 19.5 million Americans, or 8.2% of the population over the age of 12, were taking illegal drugs. "Recent illicit drug use" refers to use of an illicit drug within the month preceding the investigation by the U.S. Department of Health and Human Services. Cannabis was found to be the most commonly used illicit drug, accounting for 6.2% (14.6 million). An estimated 2.3 million people (1.0%) are currently using cocaine, 604,000 have used crack, 1 million are using hallucinogens, and an estimated 119,000 are using heroin. [0003] To combat drug abuse and monitor this social problem, drug testing has become a standard...

Problems solved by technology

[0005] When the amount of sample collected is too large, it will cause the sample to flow into the test element in an excessive amount of liquid, and directly spread over the entire test element, so that it is too late to carry out an immune reaction related to the antigen or antibody on the test element, especially The corresponding immune reaction cannot be carried out in the area displayed by the test result of the test element, which eventually leads to the inability to detect and obtain the test result

[0006] Analyzing the reason, it is found that since the sample in the collection chamber will directly contact the sample receiving area of ​​the test element, once the sample volume is large, there will be a large amount of sample directly flowing (flooding) through the subsequent reagent reaction area, which cannot be fully tested. immune response, making detection impossible
