  • Publication number: 20140012098
    Abstract: A system, method and apparatus for determining a physiological condition within a mammal based on pH and/or temperature measurements. In one aspect, the invention is an apparatus for measuring a physiological condition within a mammal comprising: a probe for insertion into a body lumen of the mammal, the probe housing a first circuit board operably coupling a pH sensor for measuring pH and generating a pH signal indicative of the measured pH, a memory device storing parametric data unique to the pH sensor, and a first interface connector located at a proximal portion of the probe; a handle for manipulating the probe, the handle housing a second circuit board operably coupling a microprocessor for processing the pH signal, and a second interface connector; the probe connected to the handle in a manner that allows the probe and handle to be repetitively engaged and disengaged from each other.

  • Patent number: 8308652
    Abstract: A system, method and apparatus for determining a physiological condition within a mammal based on pH and/or temperature measurements. In one aspect, the invention is directed to an apparatus for measuring a physiological condition within a mammal comprising: a tubular housing extending along a longitudinal axis from a distal end to a proximal end, the housing having an internal cavity; a first opening in the elongated housing forming a first passageway into the internal cavity; an ion-sensitive field effect transistor (ISFET) for measuring pH within a body lumen of the mammal, the ISFET positioned in the internal cavity, the ISFET aligned with the first opening so that at least a portion of the ISFET is exposed via the first opening; and a first seal between the ISFET and the housing forming a hermetic seal about a perimeter of the first opening.

  • Patent number: 7892179
    Abstract: A system, method and apparatus for determining a physiological condition within a mammal based on pH and/or temperature measurements. The invention is for determining vaginal health and/or fertility status in a female mammal based on pH and/or temperature measurements of vaginal and/or cervical fluids or tissue. The invention is suited for taking either in vivo or external measurements. In one aspect, the invention is an apparatus comprising an elongated probe portion and a handle portion. In one embodiment, the circuitry of the apparatus is strategically split between the probe portion and the handle portion to facilitate a plug-and-play type of device. In another embodiment, an elongated probe is provided that has a hermetically sealed internal cavity that houses the circuitry while leaving the temperature sensor and the pH sensor exposed for direct contact with the desired biological fluid. In a further embodiment, an ISFET is used as the pH sensor.

  • Publication number: 20100036279
    Abstract: A system, method and apparatus for determining a physiological condition within a mammal based on pH and/or temperature measurements. In one aspect, the invention is directed to a method of calibrating an apparatus for taking in vivo pH measurements comprising: a) providing a probe having an elongated housing extending along a longitudinal axis, a well formed in a top edge of the elongate housing for holding fluids, a pH sensor located on a floor of the well, the well located at a distal portion of the elongated housing; b) positioning the distal portion of the elongated housing on a base of a removable cap, the removable cap having a lid in an open position; c) supplying a liquid buffered to a known pH to the well and in contact with the pH sensor; d) moving the lid of the removable cap to a closed position so that the distal portion of the elongated housing is enclosed in a cavity of the removable cap, the cavity being substantially free of visible light; and e) calibrating the pH sensor to the known pH.
