FIELD: medicine; medical engineering. ^ SUBSTANCE: method involves setting syringe body in horizontal position with additional end piece turned upward. Sealing caps are taken off from the principal and additional end pieces. Space is opened between syringe body and sealing member on the piston. The piston is moved into utmost position near tip for introducing gas. Additional rod is returned to initial position and syringe body is set in vertical position with the end piece turned down. Dosed volume of liquid drug is taken to graduation line. The principal and additional end pieces are tightly closed with cap. The syringe body is set in vertical position with the end piece turned down before usage. Space is opened between syringe body and sealing member on the piston by rotating the additional rod. The piston is displaced to dosed mark taking into account the line connecting the principal and additional graduation line. The additional rod is returned to the initial position. The liquid drug is mixed w the gas substance during 15 min. Then, sealing cap is taken off from the end piece. Needle is put on. Gas substance not mixed with the liquid drug is removed by displacing piston to dosed mark along liquid drug graduation mark. ^ EFFECT: reduced risk of traumatic complications. ^ 3 cl, 2 dwg
