Formulation preparation device

A formulation preparation device which comprises:

• (a) a valve assembly comprising a first passage, a second passage and a third passage, a main body having three apertures and a central cavity within the main body comprising a first and second valve disc, wherein the apertures in the main body access the central cavity, wherein each of the first, second and third passages has two open ends, wherein one end of each of the passages is connected to a different aperture in the main body and wherein the other end of each of the passages is connected to an aperture or opening in the device;
• (b) a first transfer spike body comprising:
• (i) a beveled point containing an opening;
• and,
• (ii) a toros-shaped conduit having an inner channel and an outer channel, wherein each of the inner and outer channels has two open ends, wherein a first end of each of the inner and outer channels is connected to the beveled point opening and
• wherein the other end of the outer channel is connected to the valve assembly's first passage;
• and,
• (c) a second transfer spike body comprising:
• (i) a beveled point having an opening;
• and
• (ii) a toros-shaped conduit having an inner channel and an outer channel, wherein each of the inner and outer channels has two open ends, wherein a first end of each of the inner and outer channels is connected to the beveled point opening, and wherein a hydrophobic air filter is sealed into the second open end of the inner channel;
• (d) a tube having open ends, wherein one end of the tube is connected to the first transfer spike body at the open end of the first transfer spike body's inner channel and wherein the other end of the tube is connected to the second transfer spike body at the open end of the second transfer spike body's outer channel;
• (e) a syringe port comprising an opening and a luer lock fitting;
• (f) a passage connecting the syringe port and the valve assembly, wherein one end of the passage is connected to the port's opening and the other end of the passage is connected to the open end of the valve assembly assembly's second passage;
• (g) an infusion spike body comprising:
• (i) a beveled point containing an opening;
• and
• (ii) a conduit connecting the opening and the valve assembly, wherein one end of the conduit is connected to the point's opening and wherein the other end of the conduit is connected to an open end of the valve assembly's third passage;
• and,
• (h) a sterilizable, gripable housing having a plurality of surfaces, wherein the housing contains the valve assembly, the hydrophobic air filter and the tube and wherein the beveled points and syringe port project from one or more of the housing's surfaces, whereby when a syringe is inserted into the syringe port and the syringe plunger is aspirated downward, the first and second valve discs are positioned in the valve assembly's central cavity such that fluid flow is permitted between the first transfer spike body and the syringe port and not between the first transfer spike body and the infusion spike body;
• and whereby when the syringe plunger is infused upward, the first and second valve discs are positioned in the valve assembly central cavity such that fluid flow is permitted between the syringe port and the infusion spike body and not between the syringe port and the first transfer spike body.
