A housing for a medicinal pump (10), which is sealed to prevent damage due to exposure of the housing to water or other liquids. The housing includes an extruded case (12) in which the various components comprising the pump (10) are enclosed. The ends of the extruded case (12) are sealed by a top cap (14) and a bottom cap (16) that are overmolded with an elastomeric material. The elastomeric material seals the top and bottom caps (14, 16) against the extruded case (12) and provides shock resistance to protect the pump from damage. An open side of the pump is sealed with a pump chassis (32) that supports a pump cassette used to infuse medicinal fluids into a patient. A bezel assembly (54) on the front surface of the pump (10) is adhesively attached thereto using a double-sided adhesive sheet (48). The double sided adhesive sheet seals the openings for a display and a keypad formed in the front surface of the extruded case (12).

Ce logement destiné à une pompe médicinale (10) est scellé afin de l'empêcher de subir un quelconque endommagement consécutif à son exposition à de l'eau ou à d'autres liquides. Le logement comprend un boîtier extrudé (12) dans lequel sont enfermés plusieurs éléments comprenant la pompe (10). Les extrémités du boîtier extrudé (12) sont scellées par un couvercle supérieur (14) et un couvercle inférieur (16), sur lesquels on a moulé un matériau élastomère, lequel scelle ces couvercles (14, 16) contre le boîtier extrudé (12) et constitue une résistance aux chocs destinée à protéger la pompe (10) de tout endommagement. Un côté ouvert de la pompe est scellé à l'aide d'un cadre (32) de pompe, lequel supporte une cassette de pompe utilisée pour perfuser des fluides médicinaux dans un patient. Un ensemble encadrement (54) est fixé de manière adhésive sur la surface antérieure de la pompe, à l'aide d'une feuille adhésive double face. Cette feuille (48) scelle les ouvertures destinées à un affichage et à un clavier, et formées dans la surface antérieure du boîtier extrudé (12).
