METHOD OF CELL SAMPLING FROM BODY TISSUES AND RELATED DEVICE Russian patent published in 2008 - IPC A61B10/02 

FIELD: medicine.

SUBSTANCE: guide-needle is inserted into affected tissue. Mandrel containing needles are inserted into guide-needle; affected area is radially punctured including surrounding tissue from different points. Biological material is aspirated in rarefied air medium though point exposure with multiple vacuum blow, until biological material appears in translucent cannula. Device for cell sampling from body tissues consists of sampler in the form of medical syringe with needle and portable vacuum device containing electrovacuum micropump, inlet valve with activator and suction line. Sampler needle is guide-needle designed to be furnished with thin mandrel containing needles. Sampler is equipped with adapter inserted into syringe piston channel and connected with vacuum device through suction line. Vacuum device is provided with receiver mounted in front of electrovacuum micropump.

EFFECT: group of inventions enables to reduce blood aspiration; to increase possibilities for puncture cell sampling and to reduce manipulation injury.
