International Classification:

A61B 5/05

US Classification:

600345, 600309, 600347, 600365

Abstract:

A sensor system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes a connection detection device, a power source, and a delay circuit. The connection detection device determines if the sensor electronics device is connected to the sensor and transmits a connection signal. The delay circuit receives the connection signal, waits a preset hydration time, and couples the regulated voltage from the power source to an electrode in the sensor after the preset hydration time has elapsed. Alternatively, the sensor electronics device may include an electrical detection circuit and a microcontroller. The electrical detection circuit determines if the plurality of electrodes are hydrated and generates an interrupt if the electrodes are hydrated. A microcontroller receives the interrupt and transmits a signal representative of a voltage to an electrode of the plurality of electrodes.

International Classification:

G05B 19/00

US Classification:

340 583

Abstract:

A medical device as provided here includes a security module configured to regulate operations of the medical device. The medical device also includes a fingerprint reader operatively coupled to the security module. The fingerprint reader is configured to detect fingerprints, and to generate fingerprint data corresponding to swiped fingerprints. The medical device also includes at least one memory element operatively coupled to the security module, and configured to maintain a list of fingerprint-secured operations of the medical device, each of the fingerprint-secured operations being linked to a respective assigned set of identifiable fingerprint data. The security module is configured to analyze a swiped set of fingerprint data, compare the swiped set of fingerprint data to identifiable fingerprint data maintained in the list, and initiate one of the fingerprint-secured operations when the swiped set of fingerprint data satisfies matching criteria for its respective assigned set of identifiable fingerprint data.

Abstract:

A pump for delivering a fluid includes a pump housing that defines at least one reservoir having a circumferentially open first end, a circumferentially closed second end and a chamber to receive the fluid. The pump includes a plunger assembly having at least one plunger arm and a cannula fluidly coupled to the plunger arm to dispense the fluid from the pump. The plunger arm is receivable within the first end of the reservoir, and the at least one plunger arm defining an internal conduit to receive the fluid from the at least one fluid reservoir. The internal conduit is fluidly coupled to the cannula. The plunger assembly is movable in a first direction relative to the pump housing to advance the plunger arm within the fluid reservoir to dispense the fluid from the fluid reservoir out of the pump via the cannula.
