Keyed fluid connector and fluid dispensing system
First Claim
1. A keyed fluid connector comprisinga) a first body including a first mating surface and having a first fluid fitting disposed in a first port in the first mating surface;
- b) a second body including a second mating surface opposable to the first mating surface and having a second fluid fitting disposed in a second port in the second mating surface, the second fluid fitting connectable to the first fluid fitting;
c) a boss extending from the mating surface of one of the first and second bodies to a distal boss surface thereby forming a recess between the first or second mating surface and the distal boss surface;
d) a keying feature comprising at least a first pin extending from the distal surface of the boss, the first pin being disposable in a first hole in the other of the first and second mating surfaces; and
e) wherein when the first body is mated to the second body with the first pin disposed in the first hole, the recessed portion of the boss provides for visual inspection of the first and second fluid fittings connected to each other.

Abstract
Multiple unique keyed fluid connectors that are not cross-connectable with each other are described. Each keyed fluid connector comprises a first body including a first mating surface and having a first fluid fitting disposed in a first port in the first mating surface; a second body including a second mating surface opposable to the first mating surface and having a second fluid fitting disposed in a second port in the second mating surface, the second fluid fitting connectable to the first fluid fitting; and a keying feature comprising at least a first pin extending from one of the first and second bodies and disposable in a first hole in the other of the first and second bodies. The connectors are particularly useful in providing a robust system for selecting a particular electrolyte from among several containers of different electrolytes, and dispensing it into an implantable power device.

10. A system for selecting and dispensing two or more liquids comprising:
-
a) a first keyed fluid connector comprising; i) a first body including a first mating surface and having a first fluid fitting disposed in a first port in the first mating surface; ii) a second body including a second mating surface opposable to the first mating surface and having a second fluid fitting disposed in a second port in the second mating surface, the second fluid fitting connectable to the first fluid fitting; iii) a first boss extending from the mating surface of one of the first and second bodies to a distal boss surface thereby forming a recess between the first or second mating surface and the distal boss surface; and iv) a first keying feature comprising at least a first pin extending from the distal surface of the first boss of one of the first and second bodies, the first pin being disposable in a first hole in the other of the first and second mating surfaces; b) a second keyed fluid connector comprising; i) a third body including a third mating surface and having a third fluid fitting disposed in a third port in the third mating surface, ii) a fourth body including a fourth mating surface opposable to the third mating surface and having a fourth fluid fitting disposed in a fourth port in the fourth mating surface, the fourth fluid fitting connectable to the third fluid fitting; iii) a second boss extending from the mating surface of one of the third and fourth bodies to a distal boss surface thereby forming a recess between the third or fourth mating surface and the distal boss surface; and iv) a second keying feature comprising at least a second pin extending from the distal surface of the second boss of one of the third and fourth bodies, the second pin being disposable in a second hole in the other of the third and fourth mating surfaces; c) a conjoining fitting including a first inlet branch in fluid communication with the second fluid fitting of the first keyed fluid connector, a second inlet branch in fluid communication with the fourth fluid fitting of the second keyed fluid connector, and an outlet branch; d) wherein the first keying feature differs from the second keying feature, thereby preventing either of the first and second bodies from being connected to either of the third and fourth bodies; and e) wherein when the system is connected, the recessed portions of the first and second bosses provide for visual inspection of the first fluid fitting, connected to the second fluid fitting, the third fluid fitting connected to the fourth fluid fitting. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A system for dispensing electrolyte into an implantable power device comprising:
-
a) a first keyed fluid connector comprising; i) a first body including a first mating surface and having a first fluid fitting disposed in a first port in the first mating surface, a second body including a second mating surface opposable to the first mating surface and having a second fluid fitting disposed in a second port in the second mating surface, the second fluid fitting connectable to the first fluid fitting; and ii) a first keying feature comprising at least a first pin extending from one of the first and second bodies and disposable in a first hole in the other of the first and second bodies; b) a second keyed fluid connector comprising; i) a third body including a third mating surface and having a third fluid fitting disposed in a third port in the third mating surface, a fourth body including a fourth mating surface opposable to the third mating surface and having a fourth fluid fitting disposed in a fourth port in the fourth mating surface, the fourth fluid fitting connectable to the third fluid fitting; and ii) a second keying feature comprising at least a second pin extending from one of the third or fourth bodies and disposable in a second hole in the other of the third or fourth bodies, wherein the first keying feature differs from the second keying feature, thereby preventing either of the first and second bodies from being connected to either of the third and fourth bodies; c) a first fluid container connected to the first body of the first keyed fluid connector, and a second fluid container connected to the third body of the second keyed fluid connector; d) a selector valve including a first inlet port in fluid communication with the second fluid fitting of the first keyed fluid connector, a second inlet port in fluid communication with the fourth fluid fitting of the second keyed fluid connector, and an outlet port; e) a dispensing valve connectable to a fill port of the implantable power device and in fluid communication with the outlet port of the selector valve; f) a vacuum pump connectable to the fill port of the implantable power device through the dispensing valve; and g) a gas supply in communication with the first fluid container and the second fluid container.
