Abstract
Systems, methods, and devices are provided for mixing very small volumes of liquids, creams, and ointments. The system includes a mixing apparatus and a flexible tube in ingredients can be added to a base formulation via a connector. The mixing apparatus can mix the contents of the tube non-invasively.
Claims18
A mixing system for mixing small volume formulations at a point-of-use center, the mixing system comprising:
- a flexible tube comprising a volume of a base formulation that is less than a volume of the flexible tube,
- a connector configured for one-way introduction of one or more external ingredients into the flexible tube while maintaining a sterile condition inside the flexible tube, and
- means for mixing the base formulation and the one or more external ingredients by applying a predetermined and varying pressure from one end of the flexible tube to another end so that the resulting formulation is uniform.
A mixing system for mixing small volume formulations, the mixing system comprising:
- a flexible tube comprising a volume of a base formulation that is less than a volume of the flexible tube,
- a connector configured for introduction of one or more external ingredients into the flexible tube, and
- pinching rollers configured to be driven along an external sidewall of the tube to apply pressure from one end of the tube, along the tube, to an opposite end of the tube and reverse the pressure application repeatedly until a resulting formulation is uniform.
