Abstract: A two compartment container adapted for the packaging of intraocular lenses, contact lenses and other small, delicate devices requiring hydrated storage is described. The devices are contained in a first, upper compartment, while a second, lower compartment contains a fluid. The two compartments are placed in fluid communication with each other by means of a narrow passage which prevents the devices in the first compartment from entering the second compartment.

Abstract: A package for materials that are to be mixed just prior to use comprises a squeezable container into which is inserted a barrel containing a plunger. One substance to be mixed is placed within the container. The second substance is placed within a compartment formed within the barrel between a pair of pistons having flexible sealing rings. Telescoping of the plunger rod into the barrel causes the upper piston to advance into the compartment. The advancing upper piston exerts hydraulic pressure causing the lower sealing piston to detach from the barrel allowing internal mixing of the substances into a mixed fluid. By squeezing the container side wall, mixed fluid may be dispensed from a forward end of the plunger rod communicating with the container interior through a series of passageways.

Abstract: A syringe holder for receiving a syringe and provided with a locking device to lock the needle assembly onto the syringe to prevent the needle assembly from dislodging during administration or loading of a viscous material. The holder is also provided with grips for control of the syringe during use.
