摘要:
Methods and devices for monitoring intra-ocular pressure of a patient using a miniature implantable sensor device are provided herein. Methods include obtaining multiple pressure measurements each day during an increment of an extended monitoring period according to a sampling program and wirelessly transmitting stored measurement data and wirelessly charging the device. Measurements and data process is performed with low power requirements such that sampling can be performed hourly for at least one week using energy stored on the miniature device and measurement data can be transmitted and the device charged rapidly when an external portable data acquisition/charging device is held in proximity to the device. In one aspect, methods include switching between differing use modes and powering the sampling device with a high impedance battery by switching between a supercapacitor and the battery with a microcontroller to perform impedance conversion.

A system and method for measuring and/or monitoring compliance and/or quality of brace usage is provided that includes one or more straps, one or more assemblies interacting with the one or more straps, and measurement mechanism(s) associated with the strap/assembly combination to generate information related to compliance and/or quality of brace usage. The systems and methods may be retrofit to existing scoliosis braces and may be used to transmit information to remote devices and/or processors. In addition, information concerning compliance and/or quality of brace usage may be communicated to a user and/or health care provider(s), e.g., through one or more signaling elements such as aural, visual and/or haptic signaling elements associated with the at least one assembly.

A universal/upgrading pulse oximeter (UPO) (210) comprises a portable unit (610) and a docking station (660, 910) together providing three-instruments-in-one functionality for measuring oxygen saturation and related physiological parameters. The portable unit functions as a handheld pulse oximeter. The combination of the docked portable and the docking station functions as a stand-alone, high-performance pulse oximeter. The portable-docking station combination is also connectable to, and universally compatible with, pulse oximeters from various manufacturers through use of a waveform generator (320, 930). The UPO provides a universal sensor to pulse oximeter interface and a pulse oximeter measurement capability that upgrades the performance of conventional instruments by increasing low perfusion performance and motion artifact immunity, for example. Universal compatibility combined with portability allows the UPO to be transported along with patients transferred between an ambulance and a hospital ER, or between various hospital sites, providing continuous patient monitoring in addition to plug-compatibility and functional upgrading for multiparameter patient monitoring systems. The image on the portable display (264, 740) is rotatable, either manually when undocked or as a function of orientation (950), In one embodiment, the docking station (660) has a web server and network interface (1410) that allows UPO data to be downloaded and viewed as web pages over a local area network (1420) or the Internet.

A glucose measurement system comprises a glucose measuring device comprising a radio frequency identification (RFID) reader, electronics configured (i) to receive one or more signals indicative of a glucose level in a sample and (ii) to determine the glucose level based on the one or more signals, and a display for providing the determined glucose level. The system includes a circuit board; an RFID chip mounted on the circuit board; an in vivo glucose sensor coupled to the circuit board and in signal communication with the RFID chip; a memory for storing digitally encoded data representing a monitored glucose level detected by the in vivo glucose sensor; and an antenna coupled to the circuit board and in signal communication with the RFID chip. The RFID reader is configured to receive the digitally encoded data representing the monitored glucose level when the RFID chip is within a predetermined range of the RFID reader.

Systems and methods for processing sensor analyte data, including initiating calibration (60), updating calibration (100), evaluating clinical acceptability of reference and sensor analyte data (80), and evaluating the quality of sensor calibration (110). During initial calibration, the analyte sensor data is evaluated over a period of time to determine stability of the sensor. The sensor (10) can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. The calibration can be updated after evaluating the calibration set for best calibration based on inclusion criteria with newly received reference analyte data. Fail-safe mechanisms are provided based on clinical acceptability of reference and analyte data and quality of sensor calibration. Algorithms provide for optimized prospective and retrospective analysis of estimated blood analyte data from an analyte sensor (10).
