Abstract
Abstract An analyzing apparatus for the purpose of analyzing samples of body fluids, comprising a sample feeding device and a measuring channel in which measuring probes are contained. In order to attain good reproducibility and uniform conditions of treatment of the samples the measuring channel is separated by a valve from a storage tank communicating with the sample feeding device.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
An analyzing apparatus designed primarily for the purpose of analyzing samples of body fluids, said apparatus comprising a measuring channel containing measuring probes, a gas impermeable and heatable storage channel having a first and a second end, means connecting said first end to said measuring channel, an inlet stub connected to said second end of said storage channel, a valve positioned in said connecting means, and a sample feed device comprising a docking unit positioned in flow communication with said inlet stub, said docketing unit including fittings for liquid and gaseous cleansing and calibrating media and a sample inlet, said fittings in flow communication with said inlet stub.
Claim 2
Dependent Claim
108 words
An analyzing apparatus designed primarily for the purpose of analyzing samples of body fluids, said apparatus comprising a measuring channel containing measuring probes, a gas impermeable and heatable storage channel having a first and a second end, means connecting said first end to said measuring channel, an inlet stub connected to said second end of said storage channel, a valve positioned in said connecting means, and a sample feed device comprising a docking unit positioned in flow communication with said inlet stub, said docketing unit including fittings for liquid and gaseous cleansing and calibrating media and a sample inlet, said fittings in flow communication with said inlet stub.
Claim 3
Dependent Claim
22 words
An analyzing apparatus according to claim 1 further comprising a metal block, and wherein said storage channel passes through said metal block.
Claim 4
Dependent Claim
16 words
An analyzing apparatus according to claim 1, wherein said docking unit is a rotatable docking disk.
Claim 5
Dependent Claim
65 words
An analyzing apparatus according to claim 1, wherein said docking unit has opposite first and second sides, and said fittings being mounted to said first side for at least one buffer solution, for cleansing and calibrating liquids, at least one gas feed pipe and for a vacuum source, as well as a sealing platelet, and wherein said second side is connectable with said inlet stub.
Claim 6
Dependent Claim
73 words
An analyzing apparatus according to claim 4, including a humidifier, a first gas source in flow communication with said humidifier, a gas supply line connected between said humidifier and one of said gas feed pipes of said docking unit for supplying humidified gas thereto, and a second gas source in flow communication with said gas supply line through valve means controlling the flow of the second gas flow to said gas supply line.
Claim 7
Dependent Claim
22 words
