The present invention relates to apparatus and methods for storing moisture-sensitive products such as moisture-curable orthopedic splinting/casting product, in flexible, preferably elongated, pouches. The product is folded into a repeating series of discrete sections where each section has at least one segment that extend along the pouch length. By configuring the product in this way, it can be efficiently packaged, stored, and dispensed. Other embodiments of the invention include closure systems that permit sealing the pouch opening when product is not being dispensed and substantially sealing the pouch around the product during dispensing.

Apparatus and methods for packaging and storing moisture-sensitive products in resealable pouches

The present invention provides a reinforceable orthopedic casting article comprising a backing and a curable resin having an activator capable of assisting in the initiation of the cure of an addition polymerizable reinforcement compound. Reinforced casts are made by providing a curable casting tape comprising a backing and a curable resin containing an activator capable of assisting in the initiation of the cure of an addition polymerizable reinforcement compound; initiating the cure of the casting tape; wrapping the casting tape into the form of a cast; applying a hardenable reinforcement compound to at least a portion of the casting tape; and allowing the casting tape to cure and the reinforcement compound to harden to form a reinforced orthopedic cast. In another method a reinforced soft cast is made by wrapping a soft casting tape into the form of a cast, wherein the casting tape comprises a backing and a curable resin; initiating the cure of the casting tape; applying an activated addition polymerizable reinforcement compound to at least a portion of the casting tape; and allowing the casting tape to cure and the reinforcement compound to harden to form a reinforced orthopedic cast.

Soft orthopedic casting article with reinforcement system

The present invention relates to colored orthipedic resins and colored orthopedic casting materials which are storage stable. In making the colored orthopedic resins and colored orthopedic casting materials, a chromophore-containing polyol is covalently bonded into a prepolymer resin.
