Abstract: The present invention relates to composition at least including (A) at least one epoxy-group terminated polyoxazolidinone, derived from at least one polyisocyanate compound and at least one aliphatic polyepoxide compound, (B) at least one compound having at least one group that is reactive towards terminal epoxy-groups, and (C) at least one solvent. The molar ratio of the epoxy groups of the polyepoxide compound to the isocyanate groups of the polyisocyanate compound is 50:1 to 2.4:1. The at least one epoxy-group terminated polyoxazolidinone is present in an amount of 50 to 95% by weight, in respect of the solid content of the composition. The sum of all components in respect of the solid content of the composition adds up to 100% by weight and where the solid content of the composition is at least 35% by weight.

Abstract: The invention is an irrigating device having a rigid housing defining a canal containing a three way valve selecting between three ends where at least one of the three stems has an elastic attachment for receiving two separate non-elastic medical input devices sharing a common chamber which common chamber communicates with the rigid housing canal. It has at least one three-way valve directing the flow of suction or fluids to graduated openings in the medial, distal and proximal direction. The medial opening is where the elastic attachment is place which defines a plurality of tubes. All of these tubes may be elastic. All may have an inner circumference for receiving a tube or syringe of corresponding outer diameter. Alternatively, one of these tubes may be elastic having an outer diameter for insertion into a tube or syringe of corresponding inner diameter so as to form an elastic, but water tight seal.
