Some solutions have a relatively short useful life after a solute is mixed with a solvent. Once such solution is a thrombolytic agent which is supplied intravenously to a patient to dissolve blood clots. The solution must be used within a few hours after the thrombolytic agent, in powder form, is dissolved in a liquid carrier such as water. At the present time, when the solution is to be administered, a nurse or other person adds a prescribed quantity of the liquid solvent into a vessel containing a prescribed quantity of the thrombolytic powder and shakes or otherwise mixes the mixture to accelerate the dissolution of the powder in the solvent. The solution must be administered shortly thereafter.
It would be desirable to provide a more sterile and foolproof system for shipping, storing and subsequently mixing a solvent and a solute to insure a precise mixture of premeasured quantities of the solvent and the solute under completely sterile conditions.
