Patent ID: 8580544

Claim:
An apparatus for introducing a biological material into a host which comprises: one or more packing units for containing a mixture solution containing a pool which comprises a plurality of magnetic supports carrying a biological material to be introduced into a host such as cells and having a size allowing entry into said host, and a plurality of said hosts; said packing unit comprising a liquid passage through which said mixture solution can pass, and a pressure adjuster which draws and discharges the solution with respect to a container provided outside by adjusting the pressure in said liquid passage, as a magnetic force control unit, an introduction treatment unit which controls a magnetic force affecting the inside of said packing unit from at least two directions with said packing unit therebetween so as to move said magnetic supports relatively with respect to said hosts in solution to introduce said biological material into said hosts, a storage unit associated with said one or more packing units for storing said solution; an attachment unit for attaching a nozzle of said pressure adjuster to a top of said storage unit, and a transfer unit which enables relative movement between said packing unit and the container, wherein said introduction treatment unit moves said magnetic supports and said host relative to each other in a state where the plurality of said magnetic supports in the solution contained in said packing unit are developed in solution by the magnetic force, in a planar form, and controls so as to move said magnetic supports in the normal direction of the developed surface, and wherein said introduction treatment unit has: a magnetic source which can apply a magnetic force to the inside of said packing unit; and the magnetic force control unit which controls said magnetic supports to move relatively with respect to said host, by changing the relative position or the velocity between said packing unit or said mixture solution and said magnetic source.
