Definitions
- This invention relates to the field of electrochemical/gas analyzers, and more particularly to the implementation of diagnostics in electrochemical/gas analyzers.
- Electrochemical/gas analysis systems are known having sensor units for specific analysis tests selectively installable in a multi-channel analysis system. Electrical connections are made between the individual sensor contacts and contacts on the analysis system.
- a major problem which prior art analysis systems fail to address is the ease with which front-end electronics with input impedances of several hundred million ohms can be damaged by electrostatic discharge (ESD) which occasionally occurs on insertion of static charged sensors.
- ESD electrostatic discharge
- a charged sensor brought into contact with an analysis system contact can apply built-up potential to the high impedance, front-end electronics, thereby damaging them.
- one prior art gas analysis system provides a diagnostic tool which may be referred to as an electrode simulator.
- an electrode simulator In this prior art analysis system, it is necessary to remove all of the sensors from the system when it is suspected that either a sensor or one channel of a multi-channel system is malfunctioning.
- the sensor simulator which is battery powered, is installed in place of the sensors and is electrically connected to the sensor contacts to provide test signals to the analysis system through the same contacts that connect the front-end and back-end electronics.
- Another prior art approach to providing enhanced testing of an electrochemical/gas analyzer system involves providing reed relays to selectively insert a test signal to the high impedance front-end electronics in place of a sensor signal. Contact testing cannot be achieved and implementing reed relays requires additional space proximate the front-end electronics.
- An electrochemical/gas analyzer providing a rugged contact system for removable sensors capable of withstanding inexpert sensor insertion or removal, providing protection for high impedance input electronics against electrostatic discharge (ESD) damage, and providing automatic connection of sensor front end electronics to diagnostics upon sensor removal has been invented.
- the present electrochemical/gas analyzer provides resilient electrical contacts as elongated contacting stampings captured between a printed circuit board and a sensor mating housing having flex in response to insertion or removal of a sensor. Alignment of the sensor with respect to an associated contact captured between the housing and printed circuit board is not critical.
- the contact stamping is easily fabricated according to known stamping methods, and is capable of simple, fully automated installation and retention between the printed circuit board and housing of the present analyzer.
- each contact stamping has a remote portion which has a spring loaded connection to a printed circuit board contact that leads to ground or diagnostics.
- each sensor contact makes initial physical and electrical contact with an arcuate (curved) portion of the stamping while the remote portion remains in contact with the printed circuit board contact.
- diagnostic circuitry which may be disposed on the circuit board, is connected through a remote portion terminus to the sensor, and further to the signal processing electronics.
- the diagnostic circuitry may include a path to electrical ground through an output of a voltage generator, or may provide a path to ground through a switch. In either configuration, static potential built up on the sensor body is drained to ground and the high impedance front-end electronics are protected from ESD damage.
- the remote portion of the contact stamping is urged off the printed circuit board, thus interrupting electrical connection with the diagnostic circuitry and leaving the sensor connected to the front end.
- the remote portion electrically connects the diagnostic circuitry to the signal processing electronics and allows for fully automated diagnostic testing of the contact, of the high impedance front-end electronics, and of the low impedance back-end circuitry while other sensors remain fully installed.

- Fig. 8b is the side, sectional view of Fig. 8a showing a sensor removed; and Fig. 8c is the side, sectional view of Fig. 8a showing a sensor partially installed.
- test signals can be provided from diagnostic circuitry 26 in the form of a discrete DC voltage or current, a repetitive series of DC step voltages or currents (simulating a sensor response output signal) , though other variations may be used.
- the source of test signals can be a digital- to-analog converter (DAC) .
- DAC digital- to-analog converter
- Other embodiments can utilize the outputs of DC voltage or current sources.
- the contact stampings 20 of the present invention having a remote portion 30 are advantageously utilized.
- the remote portion 30 is made up of an arcuate portion 32, which extends through a housing aperture and against which one or more sensor contacts 41 of an installed sensor 40 presses, and a remote portion terminus 34.
- a sensor 40 is installed within the analyzer and sensor contact 41 is electrically connected with the contact stamping 20, thus lifting the arcuate portion 32.
- sensor contact 41 is electrically connected with the contact stamping 20, thus lifting the arcuate portion 32.
- This raises remote portion terminus 34, interrupting electrical connection between the diagnostic circuitry 26 and the rest of the analyzer.
- the sensor 40 is removed, thus allowing the remote portion terminus 34 to electrically connect the diagnostic circuitry 26 to the remainder of the analyzer.
- Each contact 20 as described herein is manufactured from resilient materials and undergoes limited motion as a result of installation and removal of a sensor 40. As a result, a rugged contact stamping 20 is provided, capable of withstanding improper sensor 40 insertion and having a high insertion-removal life cycle relative to prior art sensor connector systems.
- a measurement module for the electrochemical/gas analyzer including the remote portion 30, is illustrated.
- the analyzer of the present invention will simultaneously test several aspects of a medium, such as blood, introduced through consecutively disposed sensors 40a-40g.
- a medium such as blood
- the analyzer of the present invention will simultaneously test several aspects of a medium, such as blood, introduced through consecutively disposed sensors 40a-40g.
- at least one component 42 (only one such component is shown within this figure) which provides an electrical connection to the measured medium and a sensor to measure the temperature of the medium being tested.
- a thermally insulating cover 48 is raised as shown.
- the cover 48 preferably has an opaque window 50 of a thermally insulating material such as glass or plastic. With the cover raised, installed sensors 40a-40g are exposed. By urging a compressive member 52 away from the sensors 40a-40g (to the right in Fig. 2) , any one sensor 40 can be removed from an analyzer housing 60, the latter being better illustrated in Figs. 3 and 4.
- a source 51 for the medium under test and a receptacle 53 into which the tested material flows are illustrated in Fig. 2 schematically and are known in the art.
- the source 51 can be substituted with a number of reference materials, depending on which aspects of the medium are being analyzed. Such materials may include reference gases, calibration materials, etc.
- the interior of the measurement housing has a contact housing 60 illustrated in Fig. 3.
- Contact stampings 20 are secured on a stamping retention face 62 by positioning retention members 64 across the contact stampings 20, then ultrasonically welding the retention members 64 to the stamping retention face 62.
- Other means for adhering the retention members 64 to the retention face 62 known in the art may be employed such as gluing, snap-fitting, and using screws or the like.
- a printed circuit board bottom surface 72 has input signal contacts 74 which correspond to the contact stampings 20 disposed within the housing 60 (see Fig. 3) .
- raised portions 78 of the contact stampings 20 are electrically and mechanically connected with the printed circuit board input signal contacts 74, which in turn are electrically connected to an input to the high impedance front-end circuitry 22 which may be mounted on the board 70 as in zone 71 (see Fig. 6) or externally, which could include access through a computer.
- the printed circuit board 70 also has terminus apertures 76 through which the remote portion terminus 34 of the contact stamping remote portion 30 extends when the printed circuit board 70 is installed within the housing 60. As viewed in Fig. 6, illustrating a circuit board top surface 75, proximate each terminal orifice 76 is a respective diagnostic signal contact 80 electrically connected with the diagnostic circuitry 26, also typically on the board 70, or external.
- the diagnostic signal contact 80 may communicate directly with an output 84 of a test signal generator 82 which provides both test signals and a path to ground.
- the diagnostic signal contact 80 may communicate with the output of a switch 90, the switch 90 having inputs 92, 94 from the test signal generator 82 and from a path to ground 86.
- the input signal contacts 74 and the diagnostic signal contacts 80 are typically formed of gold.
- the contact stampings 20 are typically manufactured of phosphor/bronze with a gold plating. Providing stampings and contacts of the same or similar material minimizes any thermocouple effects which may be present with dissimilar materials.
- Figs. 8a, 8b and 8c The relative positions of analyzer elements with a sensor 40 installed and with a sensor 40 removed are best illustrated in Figs. 8a, 8b and 8c.
- a cover 100 is shown in place, securing the printed circuit board 70 within the housing 60 by way of screws 102, though other means for attaching the cover are employable.
- the cover 100 has projections 104, each disposed proximate a terminus aperture 76, diagnostic signal pad 80, and remote portion terminus 34.
- the remote portion terminus 34 would describe an arc as the remote portion 30 is driven upwards by the sensor contact 41 and as the sensor contact 41 is disengaged.
- the remote portion terminus 34 could rest against an edge of the terminus aperture 76 when the sensor 40 is removed instead of returning to the diagnostic signal contact 80.
- the cover 100 also provides a stop 106 for limiting the upward travel of the remote portion 30 to prevent over-bending of the contact 20.
- Fig. 8b the sensor 40 has been removed, allowing the remote portion terminus 34 to return to physical and electrical connection with the diagnostic signal contact 80. It is in this position that diagnostic signals can be conveyed to the analyzer processing electronics via the contact stamping 20.
- the ground path can be provided either through the output of a low impedance voltage source acting as a diagnostic signal generator 82, or through a discrete path to ground 86.
- FIGs. 8a, 8b, and 8c Also visible in Figs. 8a, 8b, and 8c is the electrical and physical connection between the raised portions 78 of the contact stamping 20 and the input signal contact 74 disposed on the bottom surface 72 of the printed circuit board 70.
