A cover

Abstract

The invention provides a cover. The cover is provided with an assembly passage. A sample collection device with the cover can separate collected samples so as to separate the samples requiring secondary confirmation detection from the samples for initial detection, and so the samples requiring secondary confirmation detection can be independently sealed and sent to a detection mechanism for confirmation detection. The sample collection device can divide the collected samples into different cavities. The different cavities can realize partial connection or partition according to needs of collection, separation or detection. The samples required for the secondary detection are obtained by one detection and can be separated stored. No contamination exists among the samples for confirmation detection, the samples for initial detection and test elements so as to ensure that the effect of the secondary confirmation is not affected.

Description

technical field [0001] The invention relates to a device for collecting liquid samples, especially a cover for a device for collecting and detecting analyte in a liquid sample in the field of rapid diagnosis, such as a cover for a urine collection and detection 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 a...

Problems solved by technology

Although this can isolate the tested sample and the collected sample, the urine cup of this piston is expensive and not easy to operate. After all, pushing the piston requires a relatively large force. The wall of the wall acts as a liquid seal, and to achieve the seal effect requires a tight combination of the piston and the piston chamber

[0005] For another example, U.S. Patent No. 8992855 describes a device for collecting liquid samples, which includes a piston structure that is integrated with the cover and moves together with the cover. Although the test sample can be separated from the collected sample, when the test sample enters the detection chamber Finally, it needs to overcome a lot of pressure to enter, and the size of the lid and the mouth of the cup needs to be precisely designed, so that the piston integrated with the lid can be accurately inserted into the separation chamber

[0006] In addition, after the preliminary testing of these traditional collection and detection devices is completed, if follow-up confirmation testing is required, the entire collection and testing device needs to be transported to a confirmation testing agency for further confirmation testing, which brings many problems. Such problems: First, most of the current liquid collection and detection devices only have a preliminary detection chamber

The sample in the urine cup may be contaminated by the detection reagent

Second, when the entire device is sent to the confirmation testing agency, due to the large cup mouth, there is a risk of liquid leakage during transportation, which requires more cost to make the device have a better sealing effect, thereby minimizing leakage thirdly, after transporting the entire device to the confirmation testing agency, the confirmation testing agency needs a huge low-temperature warehouse to store the entire testing device to prevent the liquid sample from deteriorating, and to prepare for possible further confirmation testing in the future, which causes the confirmation testing agency ( It can be called a secondary testing organization) The cost has increased significantly
