摘要：
The utility model relates to the design of a syringe. The technical result is the simplification and speed of the installation process of the removable cover on the syringe body. The syringe karpulny contains a cylindrical body 1, made open at the first end to enter a replaceable karpule with an injection drug into the cavity of the body and with a through axial channel in the second end to enter into the cavity of the body part of a double-edged needle, which is designed to pierce the capsule, mounted on the first end of the case a removable cover with an axial hole 6, a rod 7 passing through this hole with a tip at one end for pressing on the carpula piston and a handle at the other end, as well as fastening means a double-edged needle at the second end of the housing 1. The removable cover is made in the form of a hollow cylinder, in the first end wall of which an axial hole is made 6. The second end of the cylinder of the cover 5 is made open with two diametrically opposite protrusions 12 directed from the cylindrical wall of the cover 5 radially inward, and the first end of the housing is made with two diametrically opposite radial protrusions 13, directed from the cylindrical wall of the housing 1 radially outward. The minimum distance Y between the protrusions 12 of the second end of the cylinder of the cover 5 is greater than the width Z of the protrusions of the first end of the housing to enable the protrusions 13 to be inserted into the cylinder cavity of the cover 5 with its subsequent rotation about the longitudinal axis 2 of the housing 1 and the placement of the protrusions 13 of the first end of the housing between the first end wall cover 5 and the corresponding protrusions 12 of the second end of the cover and thus fixing the cover 5 on the housing 1. 5 z.p. f-ly, 4 ill.Полезная модель относится к конструкции карпульного шприца. Технический результат – упрощение и быстрота процесса установки съемной крышки на корпусе шприца. Шприц карпульный содерж
