摘要： A detector unit which is capable of outputting electrical signals proportional in magnitude to the intensity of that energy in a beam thereof which lies in two different wavelength bands. A beam splitter directs energy in those bands from the entire compass of the beam to a data detector and a reference detector, and bandpass filters and optical traps in front of those detectors ensure that only energy in the selected bands and from the beam reach them. The detectors are mounted in precisely aligned relationship with each other and the beam splitter on, and are electrically isolated from, a monolithic, conductive, isothermal support which allows them to be maintained at the same, selected temperature by a system including data and reference detector heaters and a temperature responsive controller.

摘要： A transducer for nondispersive infrared gas analysis has heaters for the data and reference detectors to maintain the detectors at a selected temperature. A heater is also provided to heat the casing of an airway adapter associated with the transducer to a temperature high enough to keep condensation from forming. The detector unit is surrounded and electrostatically shielded by a boxlike component with barndoor extensions which are closed to shield the installed detector unit at that end of the shield through which the detector unit is installed. The detector unit, electrostatic shield, and a circuit board which carries power supply and preamplifier circuits are installed in the transducer housing which has separate end closures sealed thereto with a through fastener and internal guides for locating the shielded detector unit in the housing.

摘要： Infrared radiation emitter units for gas analyzers and other applications. The emitter has a substrate with a film of electrically resistive, emissive material on one of its surfaces. The emitter is so mounted on an emitter unit base that it can freely expand as the emitter heats up. A lead frame commutator, employed to electrically connect the emitter to an external power source, also facilitates the assembly of the unit. A component with a plated, parabolic surface collimates and focuses into an appropriate beam the energy generated by the emitter.

摘要： Sampling attachments or systems for infrared gas analyzers of the non-dispersive type. Major components of the system include a sampling device or cuvette, a vacuum pump for effecting a flow of the gases to be analyzed through the cuvette, a microprocessor based pump control, and a switch which is closed and allows the pump to be turned on only if an appropriate sampling cuvette is connected up to the pump. The sampling attachments are designed for medical applications--to provide readings of tidal carbon dioxide, for example. They have a minimally invasive nasal cannula for collecting the gases which are to be subjected to analysis; viz., those exhaled by a patient. These gases are conducted to the cuvette through a line which is gastight but allows moisture to escape, thereby keeping moisture mixed with the gases being analyzed from corrupting the readings outputted by the gas analyzer. The attachment can be easily and quickly disassembled and the components disposed of or sterilized and recycled if they become contaminated. Provision is made for collecting the gases after they have been discharged from the cuvette so that they will not be discharged into and perhaps contaminate the ambient surroundings.

摘要： Gas analyzers of the non-dispersive infrared radiation type which are designed to measure the concentration of one gas in a mixture of gases containing that gas. A novel, electrically modulated, stable, thick film infrared radiation emitter is employed to emit a beam of collimated, focused energy; and two electrically biased detectors are preferably used so that a ratioed, error eliminating output signal can be supplied to the failsafe, signal processing circuitry of the analyzer. The latter, and a conventional analog-to-digital convertor, supply information to a microcomputer which: (1) turns the infrared radiation emitter on and off; (2) controls a heater which keeps the infrared radiation detectors at a constant, precise temperature; and (3) controls displays of a variety of information concerning the gas being measured and the status of the gas analyzer. The microcomputer also accepts ambient temperature, barometric pressure, and other compensation factors. Typically, a disposable airway adapter will be included in the gas analyzer to confine the mixture of gases being analyzed to a path having a transverse dimension of precise and specific length and to provide an optical path across that stream of gases between the infrared radiation emitter and the infrared radiation detectors. The emitter and detectors are incorporated in a transducer head which can be detachably fixed to the airway adapter.

摘要： Gas analyzers of the non-dispersive infrared radiation type which are designed to measure the concentration of one gas in a mixture of gases containing that gas. An infrared radiation emitter is employed to emit energy at a frequency of 40-100 Hz with a system which includes a source driver and a timer; and a detector is used to intercept the attenuated beam after it has passed through the mixture being analyzed and output a signal indicative of the concentration of the selected gas. Also, a second detector is preferably provided so that a ratioed, error eliminating output signal can be supplied to the failsafe, signal processing circuitry of the analyzer. The detectors are electrically biased by way of flyback transformer based circuitry to improve the signal-to-noise ratio, and the signal processing circuitry can be adjusted to compensate for drift. The detectors are mounted on a thermally conductive substrate along with appropriate filters, a filter frame, and a cover. The signal processing circuitry and an analog-to-digital convertor supply information to a microcomputer which: turns the infrared radiation emitter on and off and controls a heater which keeps the infrared radiation detectors at a constant, precise temperature. The microcomputer also supplies temperature, barometric pressure, and other compensation factors. Typically, a disposable airway adapter with an elongated, flanged casing will be included in the gas analyzer to confine the gases being analyzed to a path having a transverse dimension of precise and specific length and to provide an optical path across that stream of gases between the infrared radiation emitter and the infrared radiation detectors. The emitter and detectors are incorporated in a transducer head which has a U-shaped recess and can be detachably fixed to the airway adapter with a detent arrangement.This application is a continuation of application Ser.

摘要： A patient's airway adapter is fitted into a patient's airway, which is a combined breathing air supply and exhaust gas fluid flow passageway. The housing of this patient's airway adapter connects directly to a standard tapered tracheostomy or endotracheal tube connection or standard tapered portions of other fittings, and in turn provides a standard tapered connection to a patient's airway. The main air and gas stream, respectively, going to and from a patient, continues to flow directly through the patient's airway adapter. Samples of the patient's gas are withdrawn through a smaller diameter sampling exhaust port in the housing. The sampled patient's gas, immediately upon leaving the main air and gas stream, passes from the interior of a hollow cylindrical hydrophobic liquid baffle, through the baffle, and then into the sampling cannula enroute to a monitor. This hydrophobic baffle is held in a sealed position within the surrounding housing. Any mucus, sputum, and/or condensed water is kept from entering the smaller diameter sampling exhaust port, and therefore from entering the sampling cannula, as it collects on the inside of a cylindrical hydrophobic liquid baffle. The hydrophobic baffle material is a hydrophobic, hollow cylindrical baffle, having an unobstructed internal diameter in all embodiments.

摘要： Vehicle-mountable steps with platforms which have stowed and operational (deployed) positions. A latch mechanism positively locks the platform in the selected position. The step is designed for vehicles equipped with a ball-and-receiver type of trailer hitch and is coupled to the receiver of the hitch. The step is easily removed when the hitch is needed for towing but can otherwise be left on the vehicle as the platform of the step is located out-of-the-way beneath the vehicle when the platform is located in its stowed position.
