Abstract:
1. A method of manufacturing a medical device, the method comprising: providing a plastic housing having a keypad mounting area and a sealing rim positioned outside the keypad mounting area; affixing a membrane keypad assembly on the keypad mounting area, the membrane keypad assembly comprising a plurality of actuation elements; and sealing a perimeter area of a plastic actuator layer to the sealing rim to form a fluid resistant seal between the plastic housing and the plastic actuator layer, wherein the plastic actuator layer overlies the membrane keypad assembly, and wherein protrusions formed on the plastic actuator layer are aligned with the actuation elements of the membrane keypad assembly; wherein sealing the perimeter area of the plastic actuator layer to the sealing rim comprises: applying an adhesive to the sealing rim; placing the plastic actuator layer overlying the membrane keypad assembly such that the perimeter area of the plastic actuator layer is aligned with the sealing rim; and applying heat and pressure to the perimeter area overlying the sealing rim such that the adhesive bonds the plastic actuator layer to the sealing rim.
