Protrudent analyte sensor

Номер: US20120004524A1

Автор: Nannette M. Van Antwerp, Udo Hoss

Принадлежит: Medtronic Minimed Inc

The methods and apparatus for detecting an analyte in blood are useful for detecting an analyte in tissue of a subject. The apparatus comprises a sensor, which comprises an elongated conductive material having a protrudent end, the protrudent end comprising an electrode that detects the presence of an analyte; a substrate affixed to the conductive material; and a support having an external surface, a proximal end, and a distal end. The conductive material is positioned on the support and the protrudent end of the conductive material protrudes beyond the distal end of the support. Optionally, the sensor is suspended within the lumen of a venous flow device. Typically, only a portion of the sensor is suspended within the lumen of the venous flow device, said portion comprising the protrudent end of the conductive material. Alternatively, the conductive material is positioned on the external surface of the intravenous infusion catheter.

The present invention provides an electrochemical sensor that employs multiple electrode areas that are exposed for contact with a body fluid, e.g., when the sensor is inserted subcutaneously into a patient's skin. The exposed electrode areas are arranged symmetrically, such that a symmetrical potential distribution is produced when an AC signal is applied to the sensor. The sensors in accordance with these teachings can advantageously be used with AC signals to determine characteristics of the sensor and thus improve sensor performance. These teachings also provide a biocompatible sensor with multiple reference electrode areas that are exposed for contact with body fluid.

In an example embodiment, one spring-biased arm extends from the lancing-device housing and includes a protrusion, and a series of recessed register surfaces are defined in a carrier for the lancets. In the engaged position, the spring-biased protrusion fully mates with the register recess under the spring-biasing influence to precisely align the active lancet. And in the retracted position, the spring-biased protrusion is deflected from engagement with the register recess as the carrier is advanced to advance a fresh lancet into the active position.

A mechanism of quantitative dual-spectrum IR imaging (QDS-IR) system for examining the breast cancer is reported. The major mechanism of the system is a pair of long-wave Infra-red (LIR) and middle-wave Infra-red (MIR) cameras with the keen temperature sensitivity and the high spatial resolution. The optical axes of cameras are calibrated by the help of two calibration makers set up on the seat for carrying an object to make them parallel to each other and locate on the same level. The design provides an imaging system with the high reproducibility supported by 7 free degrees and the high adjustability. The proposed system could ensure the positions of the object and two cameras are the same at the different time points and find the best relative positions between the seat and two cameras for the objects with different body types. Therefore, it has potential ability to detect breast cancer or monitor the effect of chemotherapy.

If this relationship satisfies a predetermined calibration criterion, a calibration signal is triggered and is displayed, and/or automatically triggers a recalibration of the haemodynamic monitoring device. For example, the pulse contour cardiac output PCCO is derived from the arterial pressure curve as the constituent component of a 1-tuple. As long as this differs from the reference cardiac output CO Ref by less than a predefined threshold value, for example 101 or 15% of the reference cardiac output, parameter determination continues without initiating a new calibration. On the other hand, if the deviation exceeds PCCO-CO ref I, the calibration signal is triggered.

Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate. If the flow rate drops to zero or close to zero, this indicates that the uterine cavity is intact and not perforated. If the flow rate does not drop to zero or close to zero, this indicates that a fluid flow is leaking through a perforation in the uterine cavity into the uterine cavity or escaping around an occlusion balloon that occludes the cervical canal.

Transducer interface system and method

Номер: US20140024956A1

Автор: Phillip Douglas Purdy, Ronald Bruce Jennings

Принадлежит: University of Texas System

A transducer interface system/method allowing conversion from an analog sensor input to a standardized analog output interface is disclosed. In some preferred embodiments the system/method permits a fiber optic pressure sensor to be interfaced to a standard patient care monitor (PCM) system using standardized Wheatstone Bridge analog interface inputs. Within this context the Wheatstone Bridge sensed output is defined by stimulus from the PCM and modulation of bridge element values by the conditioned output of an analog pressure sensor. The use of analog-to-digital-to-analog conversion in this transducer interface permits retrofitting of PCM devices having analog Wheatstone Bridge inputs with advanced patient monitoring sensors without the need for specialized modifications to the baseline PCM data collection framework. Methods disclosed herein include techniques to connect arbitrary types/numbers of analog sensors to traditional PCM systems without the need for PCM system hardware/software modifications.

Apparatus for dental confocal imaging

Номер: US20160000332A1

Автор: Nir Makmel, Tal VERKER, Yossef Atiya

Принадлежит: Align Technology Inc

An apparatus for dental confocal imaging comprises an illumination module for generating an array of light beams, an optics system for confocal focusing of the array of light beams and a probe head with a light-guiding part having an entrance face and an exit face. The illumination module, the optics system and the probe head are arranged such that the array of light beams from the illumination module passes through the optics system, enters the light-guiding part via the entrance face and exits the light-guiding part via the exit face. The optics system is configured such that, after having passed through the optics system, the outermost marginal rays of the outermost light beams with respect to the optical axis of the optics system are parallel or divergent to the optical axis.
