Abstract

Изобретение относится к захватывающему иглу (4) устройству для безопасного шприца, содержащего цилиндр (1), в который вставлен соединительный хвостовик (41) иглы (4) или вставленную втулку (3), предназначенную для установки соединительного хвостовика (41) иглы (4), при этом в соединительном хвостовике (41) иглы (4) или во втулке (3) выполнена цилиндрическая полость (32) с коническим скатом (31), и цилиндр (1) дополнительно содержит вставленный плунжер (2) с установленным на передней поверхности коническим адаптером (21) с проходящей вперед цилиндрической выступающей частью (212), при этом в это же время в хвостовике (41) иглы (4) или во втулке (3), предназначенной для установки соединительного хвостовика (41) иглы (4), выполнена поперечная прорезь (33), в которую вставлена пластина, отличающемуся тем, что вставленная пластина выполнена в виде захватывающей пластины (34), которая имеет круглое отверстие (341) по центру, при этом край по периметру этого круглого отверстия (341) приспособлен к увеличенной эластичности в радиальном направлении посредством создания внутренней кромки (3410) в форме конической юбки, сужающейся в направлении наружу от цилиндра (1) шприца. Другим объектом изобретение является безопасный шприц, содержащий упомянутое выше иглозахватывающее устройство, при этом принцип этого шприца заключается в том, что на внутренней стороне цилиндра (1) шприца выполняется выступающая часть (12) на внутреннем периметре перед передним краем плунжера (2), при этом это место соответствует такому положению плунжера (2) в полости цилиндра (1) шприца, где край (2101) по периметру основания (210) конического адаптера (21) плунжера (2) находится перед захватывающей пластиной (34), и в то же время передний конец цилиндрической выступающей
