Abstract
Abstract A console rack for anaesthesia equipment, the rack having apparatus whereby an anesthesia unit can be plugged into position by access from the front of the rack and held in that position. The plug apparatus may be plug or socket elements for receiving mating connecting elements on an anaesthesia unit and may be appropriately interconnected by fluid circuit pipework built into the rear of the console rack. Bays on the rack for receiving anaesthesia units, and anaesthesia units for fitting in these bays may be designed on the modular principle.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
90 words
Anaesthesia equipment including a rack, an anaesthesia unit plugged into position on said rack, at least two fluid-connecting elements on the rack, at least two mating elements on said anaesthesia unit, each one of said fluid-connecting elements engaging with one of said mating elements in plug-in fashion to effect a fluid-conveying connection, an inlet for fluid, an outlet for fluid, and fluid-circuit pipework means fixed to the rack for interconnecting both said fluid inlet with one of said fluid-connecting elements and said fluid outlet with another of said fluid-connecting elements.
Claim 2
Dependent Claim
90 words
Anaesthesia equipment including a rack, an anaesthesia unit plugged into position on said rack, at least two fluid-connecting elements on the rack, at least two mating elements on said anaesthesia unit, each one of said fluid-connecting elements engaging with one of said mating elements in plug-in fashion to effect a fluid-conveying connection, an inlet for fluid, an outlet for fluid, and fluid-circuit pipework means fixed to the rack for interconnecting both said fluid inlet with one of said fluid-connecting elements and said fluid outlet with another of said fluid-connecting elements.
Claim 3
Dependent Claim
55 words
Anaesthesia equipment according to claim 1 in which said rack and said anaesthesia unit have fluid connecting and mating elements allowing said unit to be plugged into position from the front of said rack, the axes of at least some of said fluid connecting and mating elements being perpendicular to the plane of said rack.
Claim 4
Dependent Claim
60 words
Anaesthesia equipment according to claim 1 in which said rack and said anaesthesia unit have fluid connecting and mating elements allowing said unit to be plugged into position from above and to the front of said rack, the axes of at least some of said fluid connecting and mating elements lying in or parallel to the plane of said rack.
Claim 5
Dependent Claim
54 words
Anaesthesia equipment according to claim 1 in which said rack has a front face and a top face perpendicular to said front face, said top face being provided with mating elements having axes perpendicular to said top face, and said front face being provided with mating elements having axes perpendicular to said front face.
Claim 6
Dependent Claim
83 words
Anaesthesia equipment according to claim 1 including first and second fluid connecting elements secured to the rack, a by-pass connection interconnecting said first and second fluid connecting elements, and sealing means including valve means operable by the presence of first and second mating elements engaged with said first and second fluid connecting elements respectively to allow fluid to flow through said first and second fluid connecting elements, and in the absence of said mating elements allowing fluid to flow along said by-pass connection.
Claim 7
Dependent Claim
18 words
Anaesthesia equipment according to claim 1 and having one or more anaesthesia units secured thereto without plug connections.
Claim 8
Dependent Claim
95 words
Anaesthesia equipment according to claim 6 in which a gas mixer unit and a selector valve are secured to the rack without plug connections, the rack has two or more sets of inlet and outlet fluid connecting elements each for engaging mating elements of an anaesthetic vaporizer, and said fluid circuit pipework means connects said gas mixer unit, said selector valve and said inlet fluid connecting elements in such a way that said selector valve may be operated to direct gas from said mixer unit to said inlet fluid connecting element of any selected set.
Claim 9
Dependent Claim
55 words
Anaesthesia equipment according to claim 7 in which said selector valve is connected by further fluid circuit pipework means to said outlet connecting elements of said sets and is operative to direct gas from said outlet connecting element of any selected set to a supply outlet, said selector valve being connected to said supply outlet.
Claim 10
Dependent Claim
19 words
Anaesthesia equipment according to claim 1 and comprising a number of defined bays each for receiving an anaestheSia unit.
Claim 11
Dependent Claim
43 words
Anaesthesia equipment according to claim 9 in which some or all of said bays are provided with indexing means for cooperating with indexing means on anaesthesia units to ensure that only a particular type of unit may be mounted in a particular bay.
Claim 12
Dependent Claim
21 words
Anaesthesia equipment according to claim 9 in which some or all of said bays have outlet and inlet fluid connecting elements.
Claim 13
Dependent Claim
19 words
Anaesthesia equipment according to claim 9 in which some or all of said bays have electrical plugs or sockets.
Claim 14
Dependent Claim
35 words
Anaesthesia equipment according to claim 9 in which some or all of said bays are designed on the modular principle to receive anaesthesia units constructed to a standard measure of length or width or both.
