Abstract: The present invention is directed towards a placement device for a flat Doppler probe and a method of use that allows for hands-free use of a flat Doppler probe. The device replaces gel for transmitting and receiving ultrasound signals or alternatively encapsulates the gel. The placement device includes a hydrophilic surface that contacts a patient and allows for the transmission and receiving of ultrasound signals. The placement device eliminates the use of gel for easier clean up and optimizes the transmission of ultrasound signals. The placement device includes an adhesive on the patient contacting surface that allows the placement device to adhere to a surface on a patient.

Abstract: One aspect of the present invention provides an electronic system accessible via a collaborative subscription service to facilitate improved access and analysis of patient data relevant to Polyvascular disease. In one specific embodiment, the electronic system is used by physicians and health care service providers to aggregate relevant medical data points, as the electronic system provides recommendations and analysis of patient care for specific Polyvascular symptoms and conditions. These data points are collected through appropriate medical devices and are transmitted for storage and access within the operational environment. One embodiment of the service also enables a collaborate environment for communication between various health care providers, professionals, and the patient regarding specific patient conditions. Accordingly, improved diagnosis, treatment, and monitoring of the various conditions related to Polyvascular disease can be deployed for the patient.

Abstract: The invention provides a device for contacting a surface of a patient's body to determine a physiologic parameter in a measurement region of a tissue of the patient. The device typically comprises a sensor responsive to the physiologic parameter and a probe housing the sensor. The probe is constructed to allow the sensor to be secured at a sensing site adjacent to the measurement region, without disturbing the blood flow within the measurement region of the tissue. The device may also include a means for reducing interference in the sensing area. Preferably, the device further comprises an indicating means operably connected to the sensor for indicating an analyte quantity and/or concentration associated with the physiologic parameter.

Abstract: An automatic skin perfusion measuring system including instrumentation that automatically analyzes perfusion measurements to identify motion artifact and SPP values and a sensor placement device is provided. The instrumentation is configured to ignore motion artifact. Perfusion measurements are designated as SPP values if various criteria are met. SPP value criteria pertain to factors including cuff pressure, perfusion, perfusion change percentages relative to previous and subsequent perfusion measurements, and whether perfusion measurements are increasing or decreasing relative to previous and subsequent perfusion measurements. The sensor placement device assures reliable data is produced when multiple measurements are desired.

Abstract: A device is provided for assessing impairment of blood circulation in a patient, such as that in perfusion failure, by measurement of blood flow adjacent a mucosal surface accessible by a mouth or nose and connecting with the gastrointestinal tract or upper respiratory/digestive tract of a patient. The device includes a blood-flow sensor adapted to be positioned adjacent a mucosal surface with a patient's body and measuring blood flow in adjacent tissue and a PCO.sub.2 sensor adapted to be positioned adjacent the mucosal surface and measuring PCO.sub.2. In addition a pH sensor may be used in combination with the blood flow determination. A method of detecting perfusion failure is also disclosed. The method includes utilizing blood-flow measurements in conjunction with a surface perfusion pressure index and/or an optical plethysmography index to more accurately assess perfusion failure. These measurements may also be supplement by taking measurements of pH, sublingual PCO.sub.2, and Sa O.sub.2.
