FIELD: medicine. ^ SUBSTANCE: invention refers to medical equipment, and can be used in radiopaque contrast agent dosing. The medical device contains a number of vessels, a connector preventing agent backflow, and flow passage opening/closing means. The number of the vessels involves the first vessel for first fluid supply, the second vessel for second fluid supply different from the first fluid in a liquid composition, and a mixing vessel for mixing the first fluid and the second fluid therein. The connector comprises the first flow passage whereto the first vessel attached and wherethrough the first fluid supplied from the first vessel passes, the second flow passage whereto the second vessel attached and wherethrough the second fluid supplied from the second vessel passes, the third flow passage whereto the mixing vessel attached and wherein the first flow passage and the second flow passage, and an outlet connected to the third flow passage respectively are incorporated. The means preventing agent backflow are provided respectively in the first flow passage and the second flow passage and prevent the backflow in the flow passages. The flow passage opening/closing means which is provided in the third flow passage on an adapter where the first flow passage and the second flow passage are integrated with the third flow passage, or on a portion on a side of the outlet with respect to the adapter and designed for opening/closing the third flow passage. The medical device is used for mixing in the mixing vessel the first fluid and the second fluid supplied respectively from the first vessel and the second vessel into the mixing vessel through the connector by means of setting the flow passage opening/closing means in a closed position, and discharging the mixed fluid through the outlet by setting the flow passage opening/closing means in an open position. ^ EFFECT: invention provides the fact that while mixing the first fluid with the second fluid, it is possible simply to mix the fluids together. ^ 8 cl, 14 dwg |
