DEVICE FOR PERFORMING VACUUM FINE NEEDLE ASPIRATION BIOPSY UNDER ULTRASOUND VISUAL CONTROL Russian patent published in 2021 - IPC A61B10/02 

FIELD: medical equipment.

SUBSTANCE: device for performing a vacuum fine needle aspiration biopsy under ultrasound visual control includes a syringe with a needle for taking cellular material from the organ under study. An electric vacuum compressor, a metal container with a vacuum meter, the first and the second foot switches, the first and the second electromagnetic valves and a foot pedal are introduced into it. The electric vacuum compressor is connected to a 220 V grid and the first foot switch to turn on the compressor and is connected with a high-density pneumatic hose to the metal container to create a vacuum of -0.8 bar in it, measured by the vacuum meter. The syringe with the needle is connected to a high-strength hose using an adapter and is installed with the possibility of taking cellular material from the organ under study after pressing the second switch to activate the first electromagnetic valve and feeding through it, through high-strength hoses connected by a tee, vacuum into the syringe. The foot pedal is connected to the second electromagnetic valve made with the possibility to relieve pressure in the syringe to ambient pressure, when the foot pedal is pressed to remove the syringe needle from the study area and complete the manipulation.

EFFECT: increasing the efficiency and informativeness of fine needle aspiration biopsy.
