    摘要: 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.

    摘要: 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 processing receiver/data recorder. A specially designed self-condensing pH sensor is located on the distal end of a tubular catheter which 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. The self-condensing pH sensor comprises a multi-tubular design with the catheter tubular member housing a silver chloride reference element, an ion conducting path, and an antimony sensor element isolated within an inner tubular member that is co-linearly or coaxially configured with the outer catheter tubular member. A separation means may be employed in close proximity to the pH sensor to keep the pH sensor from direct mucosal contact along the wall of the patient's airway which could possibly affect the sensor's ability to accurately measure breath pH. Centimeter markings imprinted on the catheter body and an optional light source located near the distal tip of the catheter is used to aid in proper positioning. A transmitter with an antenna is engaged to the proximal end of the catheter and transfers the observed pH data by employing one of many wireless methods, such as radio-frequency (RF) energy. Alternately, the transfer of observed pH data is accomplished by direct wire methods. A processing receiver/data recorder receives the data and provides a means for storing and retrieving the data for study by a physician. The transmitter also includes a means to evaluate the signal strength of the sensor, which comprises of periodically sending a low voltage signal to the pH sensor and reviewing the resulting wave forms. The signal strength system can detect if the pH sensor is non-hydrated, partially hydrated, or fully hydrated. The pH data is transferred or updated at specific intervals, which can be varied according to the patient's needs, to the processing receiver/data recorder that can include an alarming means for predetermined pH values.

    摘要: Disclosed is a system and method for monitoring the breath chemistry of a patient's breath using a specially designed self-condensing sensor module mounted in a mask, nasal cannula, headband with boom apparatus, or similar device for directing the patients' breath towards the self-condensing sensor. Monitoring of a patient's breath pH provided by the miniaturized self-condensing pH sensor provides for real-time monitoring of patient airway pH values. The specially designed self-condensing sensor module incorporates a data transfer means, e.g. direct wiring or by providing a transmitter with an antenna for wireless transferring of the pH data to a processing receiver. The self-condensing pH sensor comprises a multi-tubular design with the outer tubular member housing a silver chloride reference element, an ion conducting path, and an antimony sensor plug isolated in an inner tubular member that is co-linearly or coaxially configured with the outer tubular member. A transmitter with an antenna transfers the observed pH data by employing one of many wireless methods, such as radio-frequency (RF) energy. Alternately, the transfer of observed pH data is accomplished by direct wire methods. The pH data is transferred or updated at specific intervals, which can be varied according to the patient's needs, to the processing receiver that is engaged to the treatment apparatus. In the therapeutic configuration, the processing receiver computes and diagnoses the breath chemistry data and determines at what frequency the treatment apparatus should be activated.

    摘要: The present invention is a system comprising an illumination means and is mounted on a catheter wherein said illumination is generally located in the distal end of the catheter. Locating the illumination means near the distal end will simplify and facilitate precise placement of a measurement device in close proximity to the desired location. In one example, a catheter with a distally mounted pH sensor benefits from the use of an illumination means in the patient's airway such as in the oropharynx region. The illumination source of the present invention addresses catheter insertion and location using a continuous or flashing light emitting diode (LED) embedded in the distal end of the catheter to provide a visual sighting means for the physician. When the catheter, with the illumination means is inserted in the patient's airway, the illumination means functions to illuminate the distal end of the catheter and the anatomical features of the patient's airway for observation by the clinician, thereby facilitating proper placement of the measurement device.

    摘要: The present invention is directed to a container and method for shipping and storing frozen products. In particular, the present invention is directed to an insulated container for shipping and storing frozen tissue samples for an extended period of time, for example at least 72 hours. An exemplary embodiment of the container of the present invention includes a body having an open end and a product chamber lined with vacuum insulated panels, a spring assembly inside of the product chamber for supporting a lower cooling block and a stack of tissue packages (e.g. engineered tissue samples), and a lid assembly including one or more upper cooling blocks suspended therefrom. When the lid assembly is secured on the body of the container, the tissue packages are held in place between the upper and lower cooling blocks by the force of the spring assembly. The body of the container is dimensioned so that it may fit within an outer cardboard carton if desired for shipping.
