Outline of Final Research Achievements

A minimally invasive cell sampling device which using emulsification of cells by ultrasound irradiation and suction through ultra-thin needle was fabricated. This device enables sampling living cells from subepidermal tissue. The ultrasonic device consists of Langevin transducer, ultrasound horn and jig for needle. Ultrasound produced by Lengevin transducer transmitted to ultrasound horn, and focused to jig for needle. It is evaluated that ultrasound was irradiated from needle tip by measuring ultrasound intensity in water. The cell suction device has cell trap in the middle of suction path. This trap prevents inflow of tissues into the pump and protect the collecting cells. If tissues inflow into the pump, pump suction strength will be weakened.
