EXTRUDED METAL HOUSING WITH ELASTOMERIC ENDS FOR AN INFUSION PUMP

摘要

A housing for a medicinal pump (10), which is sealed to preventdamage due to exposure of the housing to water or other liquids. Thehousing includes an extruded case (12) in which the various componentscomprising the pump (10) are enclosed. The ends of the extrudedcase (12) are sealed by a top cap (14) and a bottom cap (16) that areovermolded with an elastomeric material. The elastomeric material sealsthe top and bottom caps (14, 16) against the extruded case (12) andprovides shock resistance to protect the pump from damage. An openside of the pump is sealed with a pump chassis (32) that supports a pumpcassette used to infuse medicinal fluids into a patient. A bezel assembly(54) on the front surface of the pump (10) is adhesively attached theretousing a double-sided adhesive sheet (48). The double sided adhesivesheet seals the openings for a display and a keypad formed in the frontsurface of the extruded case (12).
