The invention belongs to the field of
medical instruments, and particularly discloses a transfusion device for an
intensive care unit, comprising a transfusion stand. A
bottle changing mechanism is fixed on the transfusion stand. The
bottle changing mechanism comprises a transfusion cavity and a plurality of liquid separation cavities located above the transfusion cavity, the transfusion cavitiesare communicated with a transfusion main
pipe, the plurality of liquid separation cavities and a plurality of transfusion
bottle placing tables are correspondingly arranged, the liquid separation cavities are communicated with transfusion
branch pipes, free ends of the transfusion
branch pipes are provided with bottle stopper puncture devices, sliders are vertically slidably connected between theliquid separation cavities and the transfusion cavities, reset pieces are connected between the sliders and the transfusion cavities, the sliders are connected with drivers for driving the sliders tomove vertically and downwardly, the sliders are provided with liquid outlets, the liquid outlets are internally provided with hollow blocking
buoyancy balls in a clamping manner, the heights of the
buoyancy balls are the same, one blocking
buoyancy ball is not internally filled with gravity particles, and the other blocking buoyancy balls are all internally filled with gravity particles, and the adjacent blocking buoyancy balls are communicated with each other through hoses. The transfusion device can achieve automatic bottle changing.
