Abstract: The accurate measurement of inspired and expired gas volume flow and gas composition are important in respiratory therapy. The invention provides a gas flow sensor for a ventilator comprising: a flow path extending between a first end that connects to a supply of gas and a second end that couples to a patient airway interface; and a constant temperature anemometer sensor arranged within the flow path between those ends. It further comprises a sampling port that may be coupled to a gas analyser device; and an orifice which is in fluid communication with the flow path and the sampling port so that, in use, gas may be drawn from the flow path for analysis, the gas being drawn from the flow path at a position located between the anemometer sensor and the first end.

Abstract: A personal entertainment system calibrated and controlled by the biological or physiological condition of a user is disclosed. The entertainment system includes a media player; a sensor operative to detect biological parameters and generating a control signal in response to the detected parameters, the sensor being operably coupled to the media player; and a processing element which associates the control signal to at least one type of media preference, and causes the media player to provide media stimuli based on the control signal. Thus the media stimuli provided by the entertainment system is specific to the individual preferences and detected condition of the user.

Abstract: A flexible elongate member such as a pressure guide wire (1000) includes an electrical device such as a pressure sensor (1002). The pressure sensor (1002) is electrically connected to conductive bands (304), (306) and (308) located on electrical connector (300). The electrical connector is attached to core wire (602) and shaft or hypotube (704). The use of electrical connector (300) helps minimize the assembly time of pressure guide wire (1000), as well as minimize some of the assembly problems associated with prior art designs such as pressure guide wire (100).

Abstract: A breath sample reservoir comprises a container for storing a sample of breath, the container defining a sealable aperture through which the breath sample can be introduced into the container, the container being provided with a bactericidal material to inhibit reproduction of bacteria within the container.
