Diagnostic device for e.g. identifying or quantifying pathogen, has component provided with stopper, which includes aperture for opening or closing channel of throughflow system i.e. micro-throughflow system

摘要

The device has a component provided with a stopper (1) for opening and closing of a channel of a throughflow system i.e. micro- throughflow system. The stopper includes an aperture (8) for opening or closing the channel of the throughflow system. The aperture is provided with hydrogel, a diaphragm or wax. The throughflow system is provided on a substrate, which includes a surface area. A biochip is used for execution of a diagnosis. The channel exhibits a diameter of less than 1 millimeter, preferably from up to 150 micrometer. Independent claims are also included for the following: (1) a method for changing of switching possibilities of a device (2) a method for execution of a diagnosis with a diagnostic device.
