Abstract: An optical sensor having a cover layer, an emitter disposed on a first side of the cover, a detector disposed on the first side of said cover, and a plurality of stacked independent adhesive layers disposed on the same first side of the cover, wherein the top most exposed adhesive layer is attached to a patient's skin. Thus, when the sensor is removed to perform a site check of the tissue location, one of the adhesive layers may also be removed and discarded, exposing a fresh adhesive surface below for re-attachment to a patient's skin. The independent pieces of the adhesive layers can be serially used to extend the useful life of the product.

Abstract: A memory in a sensor is used to store multiple coefficients for a physiological parameter. In one embodiment, not only are the sensor's specific calibration coefficients stored in a memory in the sensor for the formula to determine oxygen saturation, but multiple sets of coefficients are stored. The multiple sets apply to different ranges of saturation values to provide a better fit to occur by breaking the R to SpO2 relationship up into different pieces, each described by a different function. The different functions can also be according to different formulas for determining oxygen saturation.

Abstract: An apparatus and method for controlling the output of an oxygen concentrator wherein an oxygen concentrator indicator is comprised of an oxygen sensor monitor and circuit board which receives a gas sample from the concentrator, the oxygen concentrator indicator circuit board converts the concentration of oxygen to a DC voltage range from 0 to 1 volt corresponding to 0 % to 100 % oxygen. A plurality of set-point amplifiers accept the voltage and feed the voltage to a logic block where the voltage is analyzed to insure that only one of a plurality of solid state relays is energized at a time. A plurality of taps on an AC motor winding are selectively energized by the solid state relays to drive the oxygen concentrator at a pre-determined rate in response to the concentration of oxygen generated by the concentrator.

Abstract: A sensor probe operable to transmit light of a first wavelength for scattering by a tissue sample is described for use with a pulse oximeter (310, 410) designed to operate with another type of sensor probe (302, 402) which transmits light of a second wavelength. The sensor probe (302, 402) includes at least one source of light (306, 308; 406, 408) for transmitting light of the first wavelength for scattering and/or absorption by the tissue sample. At least one detector (314, 414) is included for detecting light of the first wavelength affected by the tissue sample and generating a signal in response thereto. An encoder (420) in the sensor probe (402) transforms the signal to a form which may be employed by the oximeter.

Abstract: Apparatus for cooperating with an endotracheal tube (10) or face mask when used on a pediatric or neonate patient, to limit excessive rebreathing of expired air and to assure the safe placement of the tube (10), the apparatus including a colorimetric carbon dioxide indicator (20) for sensing that the tube (10) has been placed in the trachea rather than the esophagus. The apparatus further includes a housing (21) for the indicator (20) which housing (21) includes a port (25), a ventilation port (22) and an internal space where the indicator (20) is mounted. The volume of the housing internal space is selected to limit the deadspace volume of the device to less than 10 cubic centimeters to thus avoid excessive rebreathing of expired air by the patient, while at the same time avoiding an undesirably high airflow resistance in the system.

Abstract: A microphone signal attenuating breathing mask body having a gas port for inhalation of a gas to the wearer in a flow stream therethrough. A demand microphone is mounted to the mask and is coupled to an electromagnetic switch responsive to a predetermined magnetic field for switching from an actuation to an attenuation position to block transmission of sound from the microphone. An air vane is pivotally mounted on the mask body and is formed with an impingement pad positioned in the flow stream and mounts an activating magnet disposed adjacent the switch. The vane is normally disposed in a normal position such that the magnet is in an activating position and the electromagnetic switch is in the actuation position such that the microphone is active for transmission of audio signals. Upon inhalation by the wearer, the vane is responsive to the impingement of the air stream on the impingement pad to move the vane to a displaced position moving the magnet to the deactivating position, switching the switch to the attenuation position to block transmission of audio signals from the microphone.
