Abstract

1. Медицинский инструмент, предназначенный для применения в качестве держателя пробирки для биологической жидкости, содержащий:корпус; исполнительный блок, прикрепленный к корпусу с возможностью поворачиваться на оси, в указанном исполнительном блоке имеется полость для втягивания;иглу, способную находиться в первом положении, в котором она выдвинута вперед из корпуса за его пределы, и во втором положении, в котором она располагается внутри корпуса и в полости для втягивания; имеханизм втягивания, включающий иглодержатель, пружину и фиксатор, при этом указанный механизм втягивания воздействует на иглу смещающим усилием, направленным в тыльную сторону, еще до выполнения втягивания, и взаимодействует с корпусом и исполнительным блоком таким образом, что поворот исполнительного блока на оси по отношению к корпусу перемещает фиксатор, тем самым освобождая пружину и позволяя ей в процессе втягивания переместить иглу из первого положения во второе положение.2. Медицинский инструмент по п.1, отличающийся тем, что биологической жидкостью является кровь.3. Медицинский инструмент по п.1, отличающийся тем, что указанным медицинским инструментом является держатель пробирки для сбора крови.
