Abstract: An apparatus that is able to detect the position of a catheter. The apparatus utilizes a catheter filled with electrically-conductive physiological saline and a connector for establishing an electrical connection between the saline of the catheter and an input of a controller. The controller includes at least one output connectable to a standard ECG lead connector, wherein the controller includes circuitry for generating a low impedance output signal. The controller provides an output which replicates the input a standard ECG patient lead connector is configured to receive. The apparatus provides a more convenient and cost effective solution for providing specialized ECG functions without having to replace a hospital's existing ECG beside monitoring equipment.

Abstract: A flow rate measuring apparatus comprises a vessel for receiving electrically conductive liquid, and a measuring element for measuring electrically the filled volume of the vessel as a function of time to provide a signal representative of the flow rate of electrically conductive liquid entering the vessel. The measuring element is disposable within the vessel and is configured to regulate the flow of electrically conductive liquid from the first side to the second side of the measuring element.

Abstract: A device (100) and method for achieving localised hypothermia during laparoscopic surgery comprises a sheath portion (101) in the form of a flexible bag-like shape which is shaped and sized so that it substantially surrounds the organ of interest in use. The sheath portion (101) comprises walls, each consisting of at least a first inner layer and a second outer layer which define a space therebetween into which catheters (104a, b) deliver and remove cooled fluid to provide a cooling effect to the organ.

Abstract: Apparatus for Detecting the Position of a Catheter Apparatus for detecting the position of a catheter comprising a catheter, electrically conductive means associated with the catheter, a connector for establishing an electrical connection between the electrically conductive means associated with the catheter and an output of the connector and a controller having at least one output connectable to an ECG patient connector, wherein the controller includes at least one input and the said at least one input includes an electrical connection from the controller to the output of the connector and wherein the controller includes means for generating a low impedance output signal.

Abstract: A pupilometer comprises image capturing means, illumination means comprising two spaced apart light sources, stimulation means, and image processing software, the illumination means generating and emitting light of a first wave-length, and the stimulation means generating and emitting light of a second wavelength. The illumination means is arranged to one or both sides of said image capturing means and, in use, shines light towards the eyeball, the image processing software receiving data from the image capturing means, and by processing said data according to an algorithm establishes the distance between the surface of the eyeball and the camera.
