A tissue-implantable sensor for measurement of solutes in fluids and gases, such as oxygen and glucose, is provided. The sensor includes: i) a detector array including at least one detector; ii) a telemetry transmission portal; iii) an electrical power source; and iv) circuitry electrically connected to the detector array including signal processing means for determining an analyte level, such as glucose level, in a body fluid contacting the detectors. The sensor components are disposed in a hermetically sealed housing having a size and shape suitable for comfortable, safe, and unobtrusive subcutaneous implantation allowing for in vivo detection and long term monitoring of tissue glucose concentrations by wireless telemetry.

This disclosure describes methods and apparatus for indicating battery cell status on a battery pack assembly used during mechanical ventilation. Embodiments described herein seek to provide methods for indicating battery cell status on the exposed exterior of a battery assembly pack both when the battery is in use and when the battery is not in use during mechanical ventilation. Embodiments utilize power from the ventilator as well as power from the battery pack itself to light the indicators during periods of battery use and non-use, respectively. Embodiments described herein further seek to provide an apparatus indicating battery cell status on the exposed exterior of the battery pack assembly during mechanical ventilation. Embodiments described herein further seek to provide an apparatus for a battery pack assembly used during mechanical ventilation. Embodiments described herein seek to provide a system for a ventilation system with an inserted battery pack assembly.

This disclosure describes systems and methods for ventilating a patient with a system that includes an accumulator for storing a gas mixture. This disclosure describes systems and methods for ventilating a patient with a system that includes an accumulator located away from the flow path that reduces/eliminates pockets of an undesirable gas mixture from entering the gas flow path and reaching the patient after a gas mixture change by utilizing a purge valve.

The present invention is a system for monitoring a patient's breath chemistry comprising a plurality of components, including a self-condensing pH sensor distally mounted on a catheter, a transmitter with hydration sensing circuitry for the pH sensor, and, a processing receiver/data recorder. The specifically designed self-condensing pH sensor located on the distal end of the catheter is designed to be inserted into the patient's airway. Monitoring of a patient's breath pH is accomplished by using the miniaturized self-condensing pH sensor, providing for real-time monitoring of patient airway pH values.

Self-condensing pH sensor and catheter apparatus

The present invention pertains to an apparatus for evaluating the signal strength from the pH sensor to determine whether the sensor is hydrated sufficiently to accurately measure pH. This is accomplished by utilizing circuitry that periodically sends a low voltage signal to a suitable pH sensor and then receiving the resulting waveforms which are analyzed by a processing receiver. The electrical connection between a suitable pH sensor and hydration monitoring circuitry is generally hard wired. In one embodiment, a processing receiver is coupled with the hydration monitoring circuitry as a single apparatus. In a second embodiment, the processing receiver can be independent and located remote from the hydration monitoring circuitry. In this embodiment, the hydration monitoring circuitry and the processing receiver are electrically connected using either hard wired techniques or wireless technology. In addition, the processing receiver can include data recording capability.
