Method and apparatus for presetting device operating levels with display
First Claim
1. A system for control of fluid delivery from a fluid reservoir by a medical infusion pump, comprising:
- a medical infusion pump having at least one electronically-controllable pumping parameter;
a mechanical key receptacle coupled to the medical infusion pump and separate from the fluid reservoir, the mechanical key receptacle being configured to receive a mechanical key having at least one non-conductive key tab; and
a plurality of electronic switches disposed proximate to the mechanical key receptacle, each switch being selectively actuatable, both individually and in combination with the other switches, by the non-conductive key tab of the inserted mechanical key, the plurality of electronic switches coupled to the medical infusion pump to control the at least one electronically-controllable pumping parameter.

Abstract
Techniques for control of fluid delivery from a fluid reservoir by a medical infusion pump are described. Setting of at least one electronically-controllable pumping parameter is determined by the use of one or more mechanical keys. The mechanical key actuates one or more electronic switches of a mechanical key receptacle coupled to the medical infusion pump. The electronic switches are coupled to the medical infusion pump to control the at least one electronically-controllable pumping parameter. Keys can be differently configured to actuate different switches corresponding to particular settings and can include display indicia showing the particular parameter value set by the key.

14. A system for control of fluid delivery from a fluid reservoir by a medical infusion pump having at least one electronically-controllable pumping parameter, comprising:
-
a mechanical key separate from the fluid reservoir comprising; a key body having a shape compatible with insertion into a corresponding mechanical key receptacle associated with the medical infusion pump, and at least one non-conductive key tab portion positioned on the key body to mechanically actuate at least one of a plurality of electronic switches disposed proximate to the corresponding mechanical key receptacle when the mechanical key is inserted into the mechanical key receptacle, wherein the plurality of electronic switches control the at least one electronically-controllable pumping parameter. - View Dependent Claims (15, 16, 17, 18)

19. A system for control of fluid delivery from a fluid reservoir by a medical infusion pump having at least one electronically-controllable pumping parameter, comprising
a key set separate from the fluid reservoir and comprising a plurality of mechanical keys, each mechanical key having a key body shape compatible with insertion into a compatibly-shaped mechanical key receptacle of the medical infusion pump, and having a unique arrangement of at least one non-conductive key tab positioned on the mechanical key to mechanically actuate at least one of a plurality of electronic switches disposed proximate to the compatibly-shaped receptacle when inserted into the compatibly-shaped mechanical key receptacle to encode a binary input setting for controlling the at least one pumping parameter.
