Abstract
Infusion systems are provided that include an infusion pump and a fluid ingress protection assembly. The fluid ingress protection assembly includes a cover assembly having an outer surface and an inner surface, a perimeter gasket disposed within a raised perimeter on the outer surface of the cover assembly, a lens coupled to the outer surface of the cover assembly, a circuit assembly coupled to the outer surface of the cover assembly, a switch assembly coupled to the circuit assembly, a shield assembly coupled to the switch assembly, the shield assembly comprising an electrostatic discharge shield and an overlay assembly coupled with the shield assembly. Methods of assembling an infusion system are also provided.
Claims20
An infusion system comprising:
- an infusion pump;
- and
- a fluid ingress protection assembly including:
- a cover assembly having an outer surface and an inner surface;
- a perimeter gasket disposed within a raised perimeter on the outer surface of the cover assembly;
- a lens coupled to the outer surface of the cover assembly;
- a circuit assembly coupled to the outer surface of the cover assembly;
- a switch assembly coupled to the circuit assembly;
- a shield assembly coupled to the switch assembly, the shield assembly comprising an electrostatic discharge shield;
- and
- an overlay assembly coupled with the shield assembly.
A method of assembling an infusion system, the method comprising:
- assembling a fluid ingress protection assembly by:
- placing a gasket within a raised perimeter of an outer surface of a cover assembly;
- coupling a lens and an optically clear adhesive to a window of the cover assembly;
- coupling a circuit assembly to the outer surface of the cover assembly with a rear adhesive layer;
- coupling a switch assembly to the circuit assembly;
- coupling a shield assembly to the switch assembly with a shielding adhesive layer, the shield assembly comprising an electrostatic discharge shield;
- and
- coupling an overlay assembly to the shield assembly with an overlay adhesive layer;
- and
- coupling the fluid ingress protection assembly to a pump control unit.
