FIELD: medicine.
SUBSTANCE: in needle remover, which contains membrane, made of resilient material, in which shaped cutout with central hole is made, in direction from membrane periphery to its centre cuts are made, which divide membrane into four equal sectors, which form petals, provide with bevels, made on each lateral section of each petal, directed from petal edge, limiting central hole, to membrane periphery. Length of each bevel constitutes not more than 1/2 of length of each lateral section of respective petal, between two adjacent bevels of adjacent petals formed is angle, apex of which is directed towards membrane periphery, wedge-shaped cutout, apex of which is directed to membrane periphery, is made symmetrically with respect to lateral sections on edge of each petal, limiting central hole. Length of wedge-shaped cutout constitutes not more than 1/2 of length of each lateral section of respective petal, with edges of petals, limiting hole, being made with possibility of deviation from membrane plane when interaction with head of needle, introduced into hole, occurs.
EFFECT: simplification of construction and increase of its reliability.
