Abstract
Abstract A disposable cartridge for use in a clinical sensing arrangement interfaces electrically with a host instrument capable of responding to electrical signals generated by detector devices (2) incorporated in the cartridge upon exposure to calibrant fluids and/or clinical fluids under examination. The cartridge includes a passage (3) linking a reservoir of calibrant fluid (4) to the detector devices and further linking said device to a closed container (5) for fluid which has been conveyed past the devices. A fluid under test can be introduced into the cartridge through the passage wall (7) at a location disposed between the reservoir and the detector devices.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
87 words
A disposable cartridge arranged to interface with a host instrument for sensing characteristics of fluids; the cartridge comprising a reservoir of calibrant fluid, at least one sensor device, a passage linking said reservoir to said at least one device, means for introducing a fluid for analysis into said passage, means for causing said fluids to flow sequentially (in either order) past said at least one device, and a closed container, linked to said passage, to collect said fluids after they have passed said at least one device.
Claim 2
Dependent Claim
87 words
A disposable cartridge arranged to interface with a host instrument for sensing characteristics of fluids; the cartridge comprising a reservoir of calibrant fluid, at least one sensor device, a passage linking said reservoir to said at least one device, means for introducing a fluid for analysis into said passage, means for causing said fluids to flow sequentially (in either order) past said at least one device, and a closed container, linked to said passage, to collect said fluids after they have passed said at least one device.
Claim 3
Dependent Claim
31 words
A cartridge according to Claim 1 comprising electrical edge connector means coupled to said at least one device and configured to interface with complementary connector means supported by said host instrument.
Claim 4
Dependent Claim
42 words
A cartridge according to either of Claims 1 or 2 wherein said closed container includes absorbent material arranged, following contact with either of said fluids, to draw a fluid so contacted past said at least one device and into said closed container.
Claim 5
Dependent Claim
28 words
A cartridge according to any preceding claim wherein said passage and the means linking said closed container to said at least one device comprise a continuous capillary duct.
Claim 6
Dependent Claim
19 words
A cartridge according to any preceding claim including breachable means for inhibiting flow of fluid into said closed container.
Claim 7
Dependent Claim
27 words
A cartridge according to Claim 5 wherein said breachable means comprises a plug disposable in the means linking said at least one device to said closed container.
Claim 8
Dependent Claim
21 words
A cartridge according to any preceding claim wherein said reservoir of calibrant fluid comprises a deformable sac constructed with curved surfaces.
Claim 9
Dependent Claim
29 words
A cartridge according to any preceding claim wherein said means for introducing a fluid for analysis includes access means to said passage, said means including a rupturably sealed aperture.
Claim 10
Dependent Claim
34 words
A sensor arrangement comprising a cartridge according to any preceding claim in combination with a host instrument, the host instrument incorporating means to utilise electrical signals derived from said at least one detector device.
Claim 11
Dependent Claim
31 words
An arrangement according to Claim 9 wherein said host instrument includes means to control the temperature of said cartridge when said cartridge is placed in interfacing relationship with said host instrument.
