Patent ID: 8263388

Claim:
An apparatus for detecting presence of a microorganism in a sample, comprising: a housing comprising: a base fixed with a first DNA primer having a nucleotide sequence that is complementary to a DNA sequence of the microorganism of interest; a fibrinogen-splitting agent that is bonded with a second DNA primer having a nucleotide sequence that is complementary to a DNA sequence of the microorganism; a rinsing unit configured to rinse the housing; and a fibrinogen adding unit configured to add fibrinogen to the housing so that the fibrinogen added will chemically reacts with the fibrinogen-splitting agent to produce a viscous substance; an ultrasonic emitter configured to emit ultrasonic signal to the housing; and an ultrasonic receiver configured to receive ultrasonic signal from the housing and transmit the received ultrasonic signal to an ultrasonic analyzer, wherein the ultrasonic analyzer determines whether the microorganism of interest exists in the sample based on the received ultrasonic signal.
