Description

Technical Field

[0001] The utility model belongs to the technical field of in vitro diagnostic reagents, in particular to a novel sample extract collection and detection device. Background Art

[0002] In vitro diagnostic reagents refer to those managed as medical devices. They include reagents, kits, calibrators, and quality control products used for in vitro testing of human samples (such as various body fluids, cells, and tissue samples) in the prevention, diagnosis, treatment monitoring, prognosis observation, health status evaluation, and prediction of genetic diseases. Sample collection and testing devices (such as blood and urine) are a common type of in vitro diagnostic reagent.

[0003] Current sample collection and testing devices are mostly operated manually, generally by dropping the sample onto a test paper with a collection swab, or by dropping the sample onto a test plate with a collection swab. However, the sealing of the test plate and the test paper for direct testing is extremely poor. Most test samples contain a large number of infectious viruses or bacteria, causing great pollution to the environment. In addition, during the testing process, the sample is in contact with the air for a long time, which can easily cause errors in the test results. Utility Model Content

[0004] The purpose of the present invention is to provide a novel sample extract collection and detection device to solve the problems raised in the above background technology.
