Description

Detection device

The invention relates to a detection device.

In the past, various tests required the combination of professionals and professional equipment; however, due to the urgency of the test, rapid screening devices have been widely circulated in the market, allowing users to conduct home tests by themselves, and the specimen can be as large as saliva or other liquid samples.

Specimen conduction methods of conventional fast screening cassettes include specimen drop-in type, crater-type extrusion type, integrated form, instrument extrusion type, etc. The sample drop-in method uses a dropper to drop the sample into the cartridge, but the risk of infection from sample splashing in this way is high. The crater-type extrusion type squeezes the saliva collection sponge directly into the opening of the cassette at a vertical angle, and the moment the saliva collection sponge is squeezed, saliva will splash, and the risk of infection is high. The integrated sample conduction method is integrated with the saliva sponge and the detection cassette, so that the operator's hand will still be close to the sponge during operation, and the risk of splash infection is also high. After the saliva is collected, the extrusion type instrument is put into the detection instrument together with the detection cassette, and is squeezed by the instrument. It has disadvantages such as inconvenient operation, high instrument cost, and large volume, and is not suitable for handheld use.

Therefore, it is necessary to provide a novel and progressive detection device to solve the above-mentioned problems.
