摘要: A hand held breath analyzer is energized when a mouthpiece tube is put into position. An ejector mechanism expels the mouthpiece, which de-energizes the system. The insertion of the mouthpiece not only cocks the ejector mechanism but closes a cover on an exhaust manifold of a breath sample passage. The breath sample passage includes a sample chamber with a port to receive a sampling tube fitting, and an auxiliary port. The exhaust manifold is long relative to the length of the sampling chamber and terminates in an orifice by means of which ambient air is drawn across a thermistor. The sampling tube communicates with a fuel cell chamber, into which breath is drawn by a diaphragm pump arranged, in its normal, uncocked condition, to inhibit the entrance of contaminants into the chamber. The diaphragm pump is actuated in response to operation of the thermistor, through a relay-tripped toggle linkage. A flag, connected to one of the toggle members, blocks the path of light from a photocell to a photoreceptor, insuring that the diaphragm pump is properly cocked for use before a breath sample is attempted to be taken.

摘要: In a breath alcohol testing device, including a breath-receiving tube, a fuel cell chamber communicating with the tube, a fuel cell within the chamber and a movable wall, for example, a diaphragm, mounted adjacent the fuel cell, to be moved reciprocably between a down position at which the wall is relatively close to the fuel cell and an up position at which the wall is relatively far from the fuel cell, the movement of the wall acting to pump breath to and from the fuel cell, the movable wall defines one wall of the fuel cell chamber, breath in the space between the movable wall and the fuel cell being in substantially unrestricted communication with the fuel cell.

摘要: A wet standard calibration system which utilizes a heat conducting foam with the liquid therein to serve as a primary heating device to avoid the need to include mechanical agitation. The system is particularly useful for generating a vapor comprising water and ethanol which can be used for the calibration of breath alcohol testers.

摘要: An alcohol fuel cell sensor and the resultant alcohol breath tester assembly. The disclosed housing creates an alcohol breath tester assembly that protects the electrode sensor from liquid ingress, maximizes the sample contact with the platinum electrode surface, and provides a smooth path facilitating laminar flow of the sample through the sensor. This, in turn, provides good flushing of the volume without creating eddies or other turbulence. Additionally, the housing can utilize a vapor barrier layer in the assembly and restricts the layer from touching the electrode surface.

摘要: A breath tester housing assembly is provided. The assembly comprises a housing having a base to be gripped by an operator, a display oriented to be in line with an operator's direct line of view while gripping the base, and a mouthpiece interface for interfacing with a removable mouthpiece so that when a subject blows into the mouthpiece, the display is not in the direct line of view of the subject. The assembly further comprises a mouthpiece for engaging to the mouthpiece interface. The mouthpiece comprises a body having a substantially planar surface.

摘要: A fuel cell assembly includes a fuel cell, a fuel cell housing, and a diaphragm. The fuel cell housing includes an endwall and an inlet port extending through said endwall. The inlet port is for admitting a breath sample into the housing. The diaphragm is coupled within the housing such that a cavity is defined between the housing and the diaphragm. The fuel cell is positioned within the cavity and is substantially concentrically aligned with respect to the inlet port.

摘要: An improved alcohol fuel cell sensor and alcohol breath tester assembly where wires for connection to the electrodes are bent to have a generally planar base portion which may be positioned toward the center of the electrodes and an upright that then extends to the outside of the case. The uprights are generally perpendicular to the base allowing the wires to exit the housing toward the center, as opposed to toward an edge.
