Problems solved by technology

Although this can isolate the tested sample and the collected sample, the urine cup of this piston is expensive and difficult to operate. After all, it takes a lot of force to push the piston. This is because the piston needs to transfer the sample. The wall of the wall acts as a liquid seal, and to achieve the seal effect requires a strong and tight combination of the piston and the piston

Embodiment Construction

[0034] The structures involved in the present invention or the technical terms used are further described below.

[0035] detection

[0036] To detect means to assay or test for the presence of a substance or material such as, but not limited to, a chemical substance, an organic compound, an inorganic compound, a metabolic product, a drug or a drug metabolite, an organic tissue or a metabolite of an organic tissue, a nucleic acid, protein or polymer. Additionally, detection means the amount of a substance or material tested. Further, assay also means immunoassay, chemical assay, enzyme assay, etc.

[0037] sample

[0038] The samples referred to in the present invention refer to those substances that can be used to detect, assay or diagnose whether there is an analyte of interest, or pure samples. The sample can be, for example, a fluid sample, and the fluid sample can be a liquid sample, and the liquid sample can include urine, blood, plasma, serum, urine, saliva and va...

Abstract

The invention provides a detection device which comprises a detection cavity body, wherein a detection cavity is formed inside the detection cavity body; a gas adjusting material is arranged between the detection cavity and an external exchanged atmosphere; when the gas adjusting material is dry, gas circulation between the detection cavity and the external atmosphere is implemented through the gas adjusting material; when the gas adjusting material is wet, gas circulation between the detection cavity and the external atmosphere is not implemented through the gas adjusting material. By adopting the structure, the detection device has the characteristics of being simple and reasonable in structure, low in use material cost and excellent in property; the gas adjusting material (such as a sponge core) has a function of preventing liquid leakage, meanwhile the air pressure inside a sample detection cavity can be effectively adjusted, a constant sample detection liquid surface can be maintained, a stable detection result can be ensured, and in addition due to adoption of an independent sample storage cavity (collection cavity), an excessive sample is not contaminated by reagents, and convenience can be brought to secondary detection.

Description

technical field [0001] The invention relates to a detection device, especially a device for collecting and detecting analyte in a fluid sample in the field of rapid diagnosis, such as a urine detection and collection device. Background technique [0002] At present, the detection devices used to detect whether the sample contains the analyte are widely used in hospitals or at home. These detection devices used in rapid diagnosis contain one or more detection reagent strips, such as early pregnancy detection, drug abuse detection, etc. Wait. This rapid diagnosis detection device is very convenient, and the detection result can be obtained on the detection reagent strip within one minute, or at most ten minutes. [0003] Drug detection is widely used, and is often used in drug control departments, public security bureaus, drug rehabilitation centers, physical examination centers, national conscription physical examination offices and other institutions. There are various typ...
