Abstract: A blood pressure analysis 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 blood pressure analysis 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.

Abstract: Methods and systems for nanopillar sensors are described. Nanopillars can be defined on a substrate, and metal deposited on the nanopillars. A thermal treatment can reflow the metal on the nanopillars forming metallic bulbs on the top end of the nanopillars. These structures can have enhanced optical detection when functionalized with biological agents, or can detect gases, particles and liquids through interaction with the metal layer on the nanopillars.

Abstract: A medical sensor extension cable includes a sensor electrical contacting interface, that receives an electrical sensor signal which indicates a physiological parameter of a patient, and a wired data interface, that connects to a data network device. An integrated circuit determines measured values of the physiological parameter based on the sensor signal, to provide an alarm limit value, to establish a presence of an alarm event as a function of a comparison of the measured values and the at least one alarm limit value, as well as to provide data elements, which indicate the measured values and the presence of the alarm event in the event of an alarm, via the data interface. A data network device includes a data connection interface for a data interface of the extension cable. A display interface provides a display signal, which indicates the measured values and the alarm limits.

Abstract: A device for monitoring a skin surface for leakage of blood at, for example, a wound or a vascular access. The device comprises a patient unit, a connection unit and a monitor unit. The patient unit comprises a patch, including an adhesive layer to be attached to the skin surface of the patient. The adhesive layer is arranged to attach the patch to the skin so that a predetermined removal force, such as 30N, is required for removing the patch from the skin surface. A patient optical fiber is arranged at the patch and has a proximal end for connection to the connection unit. A patient connector is arranged at the distal end of a connection optical fiber. The connector has an opening passing through the connector, whereby the connection optical fiber is arranged in one end of the opening. The patient optical fiber may be inserted in the other end of the opening so that the proximal end of the patient optical fiber is arranged in register with the distal end of the connection optical fiber in order to transmit light between the optical fibers. A spring is arranged in the connector for exerting a force at the patient optical fiber at a side surface thereof for preventing unintentional withdrawal of the patient optical fiber. However, when the withdrawal force is larger than the removal force of the patch, the patient optical fiber is withdrawn from the connector. Thus, the patch is not removed from the skin even when a large force is exerted on the optical fibers.
