Abstract: An optical sensor (12) generates blood pressure data by obtaining two dimensional images of the surface of the patient's body, such as in the vicinity of the radial artery in the wrist area. Blood flow in the patient causes light to be reflected off a flexible reflective surface (14) applied against the patient with a hold down pressure, and the scattering of light i s sensed with a two-dimensional array (17) of photo-detectors (18). The output of the photo-detectors during systolic and diastolic events is calibrated against known blood pressure measurements taken with a conventional air-cuff sphygmomanometer. Linear calibration relationships between output signal and blood pressure (FIG. 25) are obtained during calibration for some set of the photo-detectors. When blood pressure data is obtained from the patient, the linear calibration relationship between output signals and blood pressure is applied to the output signals from the set of photo-detectors, resulting in blood pressure data. The method provides for compensation for changes in hol d down pressure and translation or rotation of the optical sensor relative to the patient. A preferred optical sensor arrangement for use in performing th e method is also described.

Abstract: A wireless, programmable system for medical monitoring includes a base unit and a plurality of individual wireless, remotely programmable biosensor transceivers. The base unit manages the transceivers by issuing registration, configuration, data acquisition, and transmission commands using wireless techniques. Physiologic data from the wireless transceivers is demultiplexed and supplied via a standard interface to a conventional monitor for display. Initialization, configuration, registration, and management routines for the wireless transceivers and the base unit are also described.

Abstract: A wireless, programmable system for bio-potential signal acquisition (e.g., electrocardiogram (ECG) data) includes a base unit and a plurality of individual wireless, remotely programmable transceivers that connect to patch electrodes. The base unit manages the transceivers by issuing registration, configuration, data acquisition, and transmission commands using wireless techniques. Bio-potential signals from the wireless transceivers are demultiplexed and supplied via a standard interface to a conventional monitor for display.

Abstract: A device (100) includes detachable main and auxiliary batteries (101, 102) and a circuit (310) for discharging and charging the batteries (101, 102). Discharging is accomplished by an auxiliary switch (420) that connects the auxiliary battery (102) to power the device (100), a detector (422), and a main switch (424) that connects the main battery (101) to power the device (100), without interruption, when the auxiliary battery (102) drops below a predetermined voltage (508) as determined by a detector (422). Charging is performed by switches (440, 442, 446), an internal charger (444), and a controller (306). When both batteries (101, 102) are attached, the controller (306) uses the switches (440, 442, 446) to select and couple charging current generated by the internal charger (444) to the main battery (101). Once charged, the controller (306) switches to charge the auxiliary battery (102).

Abstract: A blood pressure sensor includes a source of photo-radiation, such as an array of laser diodes. The sensor also includes a two-dimensional, flexible reflective surface. The reflective surface is nominally positioned relative to the radiation source such that the radiation travels in a direction normal to the reflective surface. The reflective surface is placed adjacent to the location on the patient where the blood pressure data is to be acquired. Radiation from the source is reflected off of the reflective surface onto a two-dimensional array of photo-detectors. Systolic and diastolic blood pressure fluctuations in the patient are translated into deflections of the patient's skin. These deflections cause corresponding deflections in the two dimensional reflective surface. The associated movement of said flexible reflective surface due to blood pulsation causes scattering patterns from said reflective surface to be detected by the two dimensional array of photo-detectors. The output from the array of photo-detectors is calibrated to blood pressure in mmHg during a calibration procedure to obtain a set of calibration relationships for one or more of the individual detectors. The calibration relationship are then used during acquisition of blood pressure data to arrive at blood pressure data.

Abstract: A blood pressure sensor (12) includes a source of photo-radiation, such as a n array (30) of laser diodes (30A-I). The sensor also includes a two- dimensional, flexible reflective surface (14). The reflective surface is nominally positioned relative to the radiation source such that the radiatio n travels in a direction normal to the reflective surface. The reflective surface is placed adjacent to the location on the patient where the blood pressure data is to be acquired. Radiation from the source is reflected off of the reflective surface onto a two-dimensional array (17) of photo-detectors (18).

These deflections cause corresponding deflections in the two dimensional reflective surface.

The outp ut from the array of photo-detectors is calibrated to blood pressure in mmHg during a calibration procedure to obtain a set of calibration relationships for one or more of the individual detectors. The calibration relationships a re then used during acquisition of blood pressure data to arrive at blood pressure data.
