Access is provided to certain pulse oximetry systems utilizing a keyed sensor and a corresponding locked sensor port of a restricted access monitor. In such systems, the keyed sensor has a key comprising a memory element, and the monitor has a memory reader associated with the sensor port. The monitor is configured to function only when the key is in communications with the locked sensor port, and the memory reader is able to retrieve predetermined data from the memory element. The monitor is accessed by providing the key separate from the keyed sensor, integrating the key into an adapter cable, and connecting the adapter cable between the sensor port and an unkeyed sensor so that the monitor functions with the unkeyed sensor.

A patient monitoring network pertaining to blood glucose and other analyte measurements includes wireless blood glucose or other analyte measuring devices and a networked computer or server. Each monitoring device is associated with a patient and is configured to measure the glucose level or other analyte from a given blood sample via inserted test strips, transmit the measurements to the networked computer, and display received messages. The blood glucose monitoring device includes means for substantially reducing factors that could affect the glucose measurement such as thermal and RF interference.

A gel distribution apparatus can include modules so that each module is connected to a respective sensor of a sensor array included in headgear. Each module can be configured to facilitate the distribution of a gel onto a scalp of a patient to permit deployment of the gel at locations on the head of a patient near the sensor to which the module is adjacently positioned or attached. The modules can each include at least one flange to permit a user to pull the module away from the scalp while also pressing a compressible gel reservoir of the module toward the scalp for directing the gel onto the scalp. The pulling force can help counteract internal pressure generated from compression of the reservoir to expel the gel so that the gel flows along a desired gel flow path without excessive back pressure.

A retractor has an oximeter sensor at its tip, which allows measuring of oxygen saturation of a tissue being retracted by the retractor. The tip includes one or more openings for at least one source and detector. A specific implementation is a spinal nerve root retractor with an oximeter sensor.

A system for operating third party proprietary software on a medical monitoring device operating native proprietary software and a system for obtaining compatible third party proprietary software for operation on the monitoring device.

Systems and methods are provided for simultaneously determining impedances of a plurality of electrophysiological electrodes. Signals are injected into a first electrophysiological electrode and a second electrophysiological electrode, the injected signals differing in at least one of magnitude and phase. A magnitude and phase of an output of a differential amplifier are evaluated, where the differential amplifier is responsive to outputs of the first electrophysiological electrode and the second electrophysiological electrode. An impedance of the first electrophysiological electrode and an impedance of the second electrophysiological electrode are determined based on the magnitude and the phase of the differential amplifier output.

The present invention provides an apparatus which efficiently perform an examination based on an examination order. The apparatus includes a connection unit configured to be connected to a plurality of measurement units each of which includes a light irradiation unit which irradiates a subject with light and a reception unit which receives an acoustic wave generated from the subject irradiated with the light, a first obtaining unit configured to obtain information on an examination order; a second obtaining unit configured to obtain information on a selected one of the measurement units connected to the connection unit, and a determination unit configured to determine whether the selected measurement unit is suitable for the examination order in accordance with the information on the examination order and the information on the selected measurement unit.

A photoacoustic diagnostic apparatus is provided. The photoacoustic diagnostic apparatus includes a movement restriction unit that selectively restricts a location movement of a user input unit that receives an input signal from a user for a light irradiation unit to irradiate light, based on a location of a contact detection unit that detects whether a probe contacts a subject to be imaged.

The invention provides for a magnetic resonance imaging system (100, 300) for acquiring magnetic resonance data (142) from a subject (118) within an imaging zone (108). The magnetic resonance imaging system comprises a magnetic resonance imaging antenna (113, 113′) comprising multiple loop antenna elements (114, 114′) with multiple infrared thermometry sensors (115, 115′). The magnetic resonance imaging antenna is configured for being positioned adjacent to an external surface (119) of the subject and at least a portion of the multiple infrared thermometry sensors are directed towards the external surface. The magnetic resonance imaging system further comprises a memory (134, 136) containing machine executable instructions (150, 152) and pulse sequence instructions (140). The machine executable instructions causes a processor controlling the system to: acquire (200) the magnetic resonance data by controlling the magnetic resonance imaging system with the pulse sequence instructions; repeatedly (202) measure at least one surface temperature (146) of the subject with the multiple infrared thermometry sensors during acquisition of the magnetic resonance data; and perform (204) a predefined action if the at least one surface temperature is above a predefined temperature.
