Abstract:
The present invention provides a method for preparing solventless bonds between plastic components. The method includes the step of using infrared exposure to create bonds, and more specifically, the step of exposing a first article and/or a second article to a specific portion of the infrared spectrum. The invention further provides medical devices fabricated using infrared exposure.
Abstract:
A multilayered film (220) suitable for medical uses is coextruded in a machine direction and comprises a first layer (222) defining a pair of peripheral edges (225, 227) extending in a direction parallel to the machine direction. The film has a second layer (224) adhered to the first layer (222). The second layer (224) is positioned within the peripheral edges (225, 227) defining a stripe (223).
Abstract:
A container is provided having first and second side walls. The first side wall comprises first and second layers with the second layer overlapping a portion of the first layer to define an overlap area. A sealing flange extends from the first layer outward of the overlap area and the second side wall is connected to the first side wall along the sealing flange to define an inner chamber therebetween. The second side wall and the sealing flange define a first layered structure comprising a plurality of layers along the sealing flange. The overlap area and the second side wall define a second layered structure that has more layers than the first layered structure. The container is sealed by positioning peripheral edges of the first and second side walls into registration so that the overlap area is centrally disposed over the second side wall. Sealing energy is then applied to the first layered structure to define a peripheral seam.

Abstract:
The present invention provides a receptacle (30) for a therapeutic fluid susceptible to deterioration on exposure to a gas such as oxygen or carbon dioxide. The receptacle (30) has walls of sheet material each including at least one layer forming a barrier essentially impermeable to such gas, and a seal sealing the walls together in a region thereof. A transfer tube (40) is sealed in the seal having a proximal end in the receptacle (30), a distal en d accessible from outside the receptacle (30), a flow passage (56) extending between said proximal and distal ends, and a closure (54) blocking flow through the flow passage (56) adapted to be pierced by a tubular needle for transfer of therapeutic through the needle. The transfer tube (40) and closu re (54) are essentially impermeable to said gas.
