To provide a mixing device, a mixing tube, a drug solution injecting system, and a drug solution mixing method capable of evenly and efficiently mixing a plurality of kinds of drug solutions. The mixing device according to the present invention includes: a swirling flow generating chamber; a first inflow opening for introducing a first drug solution into the swirling flow generating chamber in a direction parallel to a central axis of the swirling flow; a second inflow opening for introducing a second drug solution into the swirling flow generating chamber so as to generate a swirling flow of the second drug solution having a specific gravity lower than that of the first drug solution; an outflow opening for discharging a mixed drug solution; and a narrowing chamber which is interposed between the swirling flow generating chamber and the outflow opening and has a space continuously narrowed toward the outflow opening.

A surgical operation training devicecomprises a simulation bodysubjected to a predetermined treatment during surgical operation training, a holderfor holding the simulation bodyfrom below, a supportfor supporting the holderworkably, a wirefor coupling the holderwith the support, and a control unitfor controlling operation of the holder. The wireis formed of a shape memory material which can contract from an original shape when a current flows through the wire. The control unitcomprises a drive signal generating meansfor supplying a current to the wireat a predetermined timing and for performing operation control on the holderwith a change in the shape of the wireby varying the supply state of current to the wire

A blood vessel model for medical training not deforming with time and approximated to a real blood vessel without using any other tool when the blood vessel wall of the simulated blood vessel is incised or cut off. The blood vessel modelincludes a simulated blood vesselsimulating a blood vessel and artificially fabricated and a basesupporting the simulated blood vessel. The simulated blood vesselhas a circumferentially exposed part and the other part buried in the base. The basehas a jointed partdisposed in a position below the simulated blood vesseland formed by joining forming edgesA,A of a cutoutextending along the simulated blood vesselto impart a tensile stress in the diameter-increasing direction to the simulated blood vessel
