Embodiment Construction

[0022] The invention provides a device and method for detecting analyte in a liquid sample. In one embodiment, the detection device has a cup for collecting a liquid sample. The liquid sample may be a urine sample. The analytes can be glucose, drugs or their metabolites.

[0023] The device uses a system of chambers to transfer a liquid sample and detect the presence of analytes in the sample. In one embodiment, the detection device has three chambers, and the liquid sample can be transferred from one chamber to another chamber by using air pressure difference. Surface tension can hold a liquid sample within a chamber when the air pressure in each chamber is approximately equal. The sample is transferred from the chamber with the highest pressure to the chamber with the lowest pressure only if there is an air pressure difference between the chambers. The air pressure difference can be in the form of an increase or decrease in internal air pressure (such as in the form of a...

Abstract

This invention provides detecting equipment and detecting method that used to detect analyzing substance in liquor sample. The equipment includes open that lead liquor sample into the first cavity, the second cavity; it is connected to the first cavity through via holes. Detecting components are set in the second cavity. The equipment also includes the third cavity; it connected to the second cavity through passage. Active component are set in the third cavity, the component has first and second position, it separate the third cavity into the first area and the second area, one exhaust port is in the first area, active component sealing cooperate with wall face of the third cavity to avoid gas mutual circulate between the first and second area. Only needs one step operation, this equipment can finish the collection and detecting of liquor sample, fussy operation process and sample second pollution is avoided, and the damage operating crew is reduced.

Description

technical field [0001] The invention relates to a detection device and method for detecting the presence or absence of an analyte in a liquid sample. Background technique [0002] Testing bodily fluids is a common practice in healthcare. Factories, government agencies, sports teams and other organizations have increasingly utilized diagnostic tests to maintain workplace safety and ensure compliance with laws, regulations and regulations. [0003] It has become a very common method to collect a liquid sample, such as urine, using a detection device and determine whether a specific analyte (such as a drug and / or its metabolite, or a marker associated with a disease) is present. Devices for such testing generally require that the sample be collected in a sample container, the skilled person inserts a test strip and submerges a portion of the test strip in the sample, and then removes the test strip to read the result. The technician may come into contact with the sample and m...
