Abstract

An apparatus is described for automatically opening and dispensing the contents of a vessel, for example, a vessel containing dialysate chemicals for dispersion into a dialysate preparation tank. The apparatus comprises a housing having an open interior region, with the vessel mounted above the housing, and a spike reciprocable within the interior of the housing between upper and lower positions. The spike pierces the vessel when the spike is moved to the upper position. The spike has an upper spike element that pierces the bottle and an integral spike body concentric with the housing permitting passage of dialysate chemicals therethrough after the spike has pierced the vessel. A drive means is proved for moving the spike relative to the housing between the upper and lower positions, so as to control the operation of the spike and the automatic release of the contents of the vessel.
