A unified dispenser for holding, mixing, and dispensing a drug, the dispenser comprising: a housing holding a diluent reservoir for containing a diluent, a drug reservoir for containing a drug, a pump assembly, energy storage means, and a tubing set connecting and defining a fluid communication path therebetween; whereby: a first aseptic connector encasing a first occlusion (53, 54), and a second aseptic connector encasing a second occlusion (56, 57); the first aseptic connector located at the diluent reservoir and the second aseptic connector located at the drug reservoir; in a storage state of the dispenser, the first and second occlusions are entirely encased within the housing and occlude the fluid communication path; and first and second pull assemblies, each extending to outside the housing; wherein the first and second pull assemblies extend into the first and second aseptic connectors and include the first and second occlusions, respectively, so that removal of the first and second pull assemblies removes the first and second occlusions from the first and second aseptic connectors, respectively, joins the diluent reservoir to the tubing set in fluid communication, joins the drug reservoir to the tubing set in fluid communication, and joins the diluent reservoir to the drug reservoir in fluid communication through the tubing set, thereby arranging the dispenser from the storage state to a use state; wherein removal of one of the first (53, 54) and second (56, 57) occlusions electrically couples the pump assembly to the energy storage means; and within the use state, the dispenser further has a mix state and a dispense state; in the mix state, the pump assembly operates in a first direction to mix the diluent with the drug; and in the dispense state, the pump assembly operates in a second direction different from the first direction to dispense a mixture of the diluent and the drug. a housing holding a diluent reservoir for containing a diluent, a drug reservoir for containing a drug, a pump assembly, energy storage means, and a tubing set connecting and defining a fluid communication path therebetween; whereby: a first aseptic connector encasing a first occlusion (53, 54), and a second aseptic connector encasing a second occlusion (56, 57); the first aseptic connector located at the diluent reservoir and the second aseptic connector located at the drug reservoir; in a storage state of the dispenser, the first and second occlusions are entirely encased within the housing and occlude the fluid communication path; and first and second pull assemblies, each extending to outside the housing; a first aseptic connector encasing a first occlusion (53, 54), and a second aseptic connector encasing a second occlusion (56, 57); the first aseptic connector located at the diluent reservoir and the second aseptic connector located at the drug reservoir; in a storage state of the dispenser, the first and second occlusions are entirely encased within the housing and occlude the fluid communication path; and first and second pull assemblies, each extending to outside the housing; wherein the first and second pull assemblies extend into the first and second aseptic connectors and include the first and second occlusions, respectively, so that removal of the first and second pull assemblies removes the first and second occlusions from the first and second aseptic connectors, respectively, joins the diluent reservoir to the tubing set in fluid communication, joins the drug reservoir to the tubing set in fluid communication, and joins the diluent reservoir to the drug reservoir in fluid communication through the tubing set, thereby arranging the dispenser from the storage state to a use state; wherein removal of one of the first (53, 54) and second (56, 57) occlusions electrically couples the pump assembly to the energy storage means; and within the use state, the dispenser further has a mix state and a dispense state; in the mix state, the pump assembly operates in a first direction to mix the diluent with the drug; and in the dispense state, the pump assembly operates in a second direction different from the first direction to dispense a mixture of the diluent and the drug.
