FIELD: medicine.SUBSTANCE: present invention relates to a syringe, and more specifically to a device obtained by improving a conventional syringe formed with a channel for an injectable stream, including an injection needle, in order to share a portion of the canal for an injectable flow, other than the injection needle, or to form a suction flow channel, completely independent of the channel for the injected flow, thereby making the liquid drug intake even smoother. Syringe comprises injection needle (10) and cylinder (20) and is formed with a channel for the injected flow passing from cylinder (20) to injection needle (10). Syringe further includes opening/closing means (400) for selectively opening and closing the channel for the injected flow； and a suction flow channel formed from a pointed hollow cap (100) to cylinder (20) and provided with a through hole formed in any of the following elements: injection needle (10), connector (500) for connection of injection needle (10) to cylinder (20), or cylinder (20), so as to provide communication between its inner part and external part, as well as by one-way valve means (300) for periodic control of opening and closing of through hole.EFFECT: syringe is configured so that separate channel for suction flow bypassing injection needle is formed in traditional syringe for smoother implementation of suction of liquid drug, thus leading to maximum convenience for user and consumer properties of product.8 cl, 16 dwgНастоящее изобретение относится к шприцу, и более конкретно к устройству, получаемому путем усовершенствования традиционного шприца, сформированному с наличием канала для инъецируемого потока, включая инъекционную иглу, с тем чтобы совместно использовать участок канала для инъецируемого потока, кроме инъекционной иглы, либо чтобы сформировать канал для всасываемого потока, совершенно независимый от канала для инъецируемого потока, тем самым делая забор жидкого лекарственного средства еще более плавным.
