Abstract:
A reconstitution device for use in reconstituting a powdered medicament contained in a sterilized sealed vial prior to injection into a patient comprising:(a) a housing having an upper section with an opening in its upper end capable of receiving a syringe, a lower section with an opening capable of receiving and housing a vial and maintaining the vial in roughly co-axial alignment with a syringe housed in said upper section; (b) a middle section connecting said upper and lower sections of said housing having a central aperture which provides a passageway for the transfer of fluid between said upper and lower sections of said housing; and (c) a hollow elongated slotted spike extending downwardly from said central aperture for a length sufficient to ensure that the lower end of the spike will pierce the top of a sealed vial when said vial is housed in the lower section of said housing, said slot extending from a point at the lower end of the spike to a point near the base of the spike so as to allow (i) rapid pressure equalization in the vial when the spike pierces the seal of the vial; and (ii) drainage of reconstituted medicament when the device is inverted so as to dispense the reconstituted medicament from the vial into the syringe.
