FIELD: medicine.
SUBSTANCE: cervical trier can be used for simultaneous collection of biological material in area of cervix of the uterus from ecto- and endocervical channel and from T-area of uterus. Cervical trier has piston, cavity for transportation of biological material and rod. Rod is provided with working organ. Working organ is capable of folding and it is made in form of rhomb-shaped elastic member with working sides which sides are connected with flexible working rod. Free end of flexible working rod is provided with drop-shaped plug. Working sides are covered with matter for holding sample. Piston is fastened to rod and it is mounted in cavity for transporting biological material. Cavity is made in form of tube-container. Plug is disposed for overlapping opening of tube-container when rod moves. Material for holding sample is made elastic and absorbing.
EFFECT: bigger amount of biological material; improved truth of results.
