Problems solved by technology

Chinese patent CN1828307 B discloses a device for detecting analytes in a fluid sample, which is convenient for sampling for confirmation testing, but when the fluid sample has poor fluidity and / or the sample size is small, the device can only barely testing, secondary confirmatory testing is not possible, and even in cases of extremely poor fluidity and / or minimal sample volume, the device cannot be used for direct testing
[0003] Many other sample collection and testing devices have difficulty extracting samples from the device for secondary testing
Many devices are complex in their design and manufacture and require the use of relatively expensive materials

Embodiment Construction

[0063] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings. It should be noted that the specific implementation is only a detailed description of the present invention and should not be regarded as a limitation of the present invention.

[0064] Such as figure 1 As shown, the present invention provides a device for detecting the presence or quantity of an analyte in a liquid sample. The detection device is in an assembled state. The detection device may include a sample collector and a sample receiving cup 1. The sample collector is used for direct or indirect Samples can be collected from the patient's body or the part that needs to be collected, or in a certain scene that has been separated from the patient's body.

[0065] The sample receiving cup 1 can receive and hold the sample collector. In some preferred ways, the sample receiving cup 1 can receive the sample collector itself or a part ...

Abstract

The invention discloses a device for detecting an analyte in a liquid sample. The device comprises a cup body, a first receiving zone for receiving a liquid sample; a flow guide channel through whicha sample can be added or collected. The flow guide channel is communicated with the first receiving area, and the bottom surface of the flow guide channel is an inclined surface. The first receiving area and the flow guide channel are arranged in the cup body. The device further comprises a secondary sampling port. The flow guide channel is a groove. A second receiving area is arranged in the groove. The second receiving area comprises a corner area used for collecting secondary samples. The invention also discloses a use method of the device for detecting the analyte in the liquid sample. Thedevice can be used for detecting the existence or quantity of analytes in a liquid sample, and can still detect the liquid sample under the condition that the liquidity of the liquid sample is extremely poor and / or the sample amount is extremely small, and an operator can conveniently suck the liquid sample to carry out secondary confirmation detection.

Description

technical field [0001] The invention relates to a device for detecting an analyte in a liquid sample. Background technique [0002] At present, there are various sample collection and testing devices for clinical or household use on the market, and some literatures have also recorded devices for detecting analytes in samples. US Patent No. 5,376,337 discloses a saliva sampling device in which a filter paper is used to collect saliva from a subject's mouth and transfer the saliva to an indicator reagent. US Patents US 5,576,009 and US 5,352,410 each disclose a syringe-type fluid sampling device. In these devices, after initial results are obtained, the collected fluid samples cannot be stored for later use in confirmatory testing. Chinese patent CN1828307 B discloses a device for detecting analytes in a fluid sample, which is convenient for sampling for confirmation testing, but when the fluid sample has poor fluidity and / or the sample size is small, the device can only bar...
