Claim Text:
1. A detection device for analyzing an analyte in a liquid sample, comprising: a) a detecting chamber for accepting a detecting element, b) a liquid sample transferring chamber, c) a film of small pores disposed between the detecting chamber and the liquid sample transferring chamber, wherein when the detection device is inserted into a liquid sample collecting chamber, liquid sample in the collecting chamber enters the liquid sample transferring chamber, but the liquid sample cannot enter the detecting chamber via said film of small pores, d) a piston disposed in the liquid sample transferring chamber, the piston being movable between a first position and a second position, wherein movement of the piston from the first position to the second position forces a part of liquid sample in the transferring chamber to enter the detecting chamber through said film of small pores, wherein when the piston is in the first position the piston prevents flow of the liquid sample from the liquid sample collecting chamber into the liquid sample transferring chamber, and wherein when the piston is in the first position, flow of the liquid sample from the liquid sample transferring chamber to the detection chamber is prevented by the film of small pores while flow of gas from the liquid sample transferring chamber to the detection chamber is not prevented, and e) a protecting element disposed adjacent the film of small pores operable to block spray of liquid sample through the small pores.
