IMPROVED MIXING SYRINGE BLOCK Russian patent published in 2018 - IPC A61M5/315 

FIELD: medicine.

SUBSTANCE: invention relates to the medical equipment, namely, to the syringe block. Syringe block contains cylinder for the drug / drugs accommodation, at that the cylinder has the front outlet for allowing the said one or more drugs to be discharged from the said cylinder through the said outlet, and the first plug located in the cylinder, and configured to axially move therein, and limiting the first volume in the cylinder along the axis before the first plug, and the second volume in the cylinder along the axis behind the first plug. First plug has the two-way valve, which has the ability to move between the insulating configuration and the open configuration to selectively provide the first volume communication with the second volume. Two-way valve has the ability to move from the insulating configuration into the open configuration by increasing the first or second volume fluid medium pressure. Syringe block further comprises the second plug, located in the cylinder along the axis behind the first plug, and configured to axially move therein, at that, the second plug provides the fluid-tight insulation at the second volume rear end. Syringe block further comprises the first rod, connected to the first plug and passing axially backward through the second plug, wherein the second plug is insulating covered by the first rod, but allows the first rod axial sliding through it; the second rod connected to the second plug so, that to move the second plug along the axis, when the second rod is moved along the axis. First rod is configured to axially move for the first plug axial movement, and increasing the pressure in the first volume, or in the second volume, causing the two-way valve movement into the open configuration, and provision of the first volume and the second volume communication.

EFFECT: invention relates to a syringe assembly, and more particularly, to a valved mixing syringe assembly suitable for mixing two or more medicaments prior to delivery.
