Infusion pump extruded metal housing with elastomeric end caps
First Claim
1. A housing for a portable medical device that protects against both mechanical shock and liquid intrusion into an interior of the housing, comprising:
- (a) a body having opposed openings disposed respectively at a first end and a second end;
(b) a first elastomeric cap shaped and sized to sealingly seat within the opening disposed at the first end of the body;
(c) a second elastomeric cap shaped and sized to sealingly seat within the opening disposed at the second end of the body; and
(d) a plurality of fasteners for coupling the first and second elastomeric caps in sealing contact with the openings of the body, said first and second elastomeric caps providing a mechanical shock resistance to the housing.

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