A recently granted patent (Publication Number: US11927599B2) describes a detection apparatus designed to treat a test substance contained in a specimen with a liquid and detect the treated substance. The apparatus includes a main body with an installation part for a cartridge housing the liquid, a lid part that opens and closes the installation part, a biasing part to open the lid, and regulators that generate resistance during the lid's opening motion. These regulators, including a first and second regulator, are strategically placed to control the lid's opening speed without reducing it, ensuring efficient operation. The apparatus also features a damper structure with a similar design for smooth lid opening and resistance generation.

Furthermore, the patent details a detection method utilizing the described apparatus. The method involves treating the test substance with liquid, detecting it, and opening the lid part while generating resistance at different timings during the opening motion. By coupling the first and second regulators and engaging them with the lid part, the method ensures controlled lid opening speeds without compromising efficiency. Additional steps in the method include reducing the opening speed when resistance is generated, pressing the sealant of a cartridge, and biasing the main body in a shaft direction. This method, with simultaneous resistance generation during the lid's opening operation, aims to streamline the detection process for improved accuracy and reliability.
