Abstract: This invention provides a quick-placement EEG electrode. The EEG electrode is fixed to a patient's scalp by a first element working in conjunction with a second element to trap hair and hold the EEG electrode in place. The EEG electrode contains a sponge that when compressed, dispenses electrolytic gel, acts as a shock absorber, and maintains contact with the scalp. The EEG electrode has a quick release mechanism for easy removal of the EEG electrode from the patient's scalp.

Abstract: A positioning device for the accurate placement of biomedical sensors. The positioning device has a template frame and one or more template arms. The template frame is able to be referenced to at least one anatomical site upon the human body, such as the sternal notch or the navel. Template arms extend from the template frame to the electrode positioning site. The length and angle of the template arms corresponds to the distance from the template frame to the electrode positioning site. The template arms reference the electrode positioning sites with respect to the template frame. The template frame references the template arms with respect to anatomical sites upon the human body.

Abstract: The present invention relates to a device for attaching sensors to the surface of the skin comprising a basic plaster 3 and a detection plaster 4 which comprises a recess so that a hollow space 5 is provided between the basic plaster 3 and the detection plaster 4. The hollow space may contain a dye solution, solid matter, or odor marker which escapes during the unauthorized removal of the sensor by tearing open the hollow space 5.

Abstract: A template has a flexible sheet with a fixed dimensional array V.sub.1 -V.sub.6 positioned in a specific size configuration appropriate for standard electrocardiographic recording. The distance between V.sub.1 and V.sub.2 is 2.00 inches.+-.0.56 inches, and the distance between V.sub.2 and V.sub.4 is 3.5 inches.+-.1.00 inch, with V.sub.3 located substantially midway between V.sub.2 and V.sub.4, and V.sub.5 is equidistant between V.sub.4 and V.sub.6.

Abstract: A self contained, compact, long term, ambulatory physiological recorder is designed for mounting directly to the body of a patient, immediately adjacent to the organ or system that is to be monitored, and is adhesively and covertly held there in place and comfortably under clothing by the very transducer, skin electrodes that detect the physiological information to be recorded, and thereby increasing continuity and decreasing artifact by obviating the need for numerous and cumbersome, hanging electrode leads as well as unsightly and cumbersome recorder pouches suspended from shoulder straps or belts.

Abstract: A disposable electrodeless electro-dermal connector device includes a flexible non-conductive sheet having a fixed array of electrical conductor strips affixed thereon and positioned in a specific size configuration appropriate for electrocardiographic recording. The connector strips have a receptor pad end adapted for electrical connection with the skin for receiving electrical impulses and a terminal connection end which is adapted for connection with an electrocardiological measuring apparatus. Receptor pads V.sub.1 and V.sub.2 are attached approximately over the sternum at the fourth intercostal space and receptor pads V.sub.3 and V.sub.4 are attached over the ribs, with the distance between V.sub.1 and V.sub.2 being 2.00 inches .+-.0.56 inches, the distance between V.sub.2 and V.sub.4 being 3.5 inches .+-.1.00 inch.

Abstract: An electrode and a method for measuring bio-electric waves are provided in which the electrode comprises a support member, a piece of absorbent fiber projecting from the support member and a non-corrosive lead coupled to the piece of absorbent fiber. Improved electrical contact between the electrode and the subject's skin is provided by allowing the piece of absorbent fiber to absorb an electrically conductive fluid.

Abstract: An electrophysiological sensing device, such as a helmet, that can be fitted to a living subject. The device includes a set of electrodes for detecting electromagnetic signals and inputting the signals to a processor. The set of electrodes includes working electrodes having at least one acquisition electrode in a selected position on the subject, and an additional electrode to be connected to the processor as a floating ground. An output of each working electrode is equipped with a first impedance adapter. A common electrical supply is provided for these first impedance adapters. A circuit capable of maintaining an intermediate electrical potential, dependant from the electrical supply, is provided at the electrical potential of the additional electrode.

Abstract: A non-invasive physiologic signs monitoring device includes a garment with electrocardiogram electrodes and various inductive plethysmographic sensors sewn, embroidered, embedded, or otherwise attached to the garment with an adhesive. The garment is in the form of a shirt. When the garment is fitted over the torso of the patient to be monitored, the electrodes and sensors generate signals in response to the physiologic signs of the patient. The signals are transmitted to a recording/alarm device where they are monitored for adverse conditions and logged. When an adverse condition or other preprogrammed condition occurs, a message is communicated to the patient by either an audio message or a display. The recording/alarm unit is also connectable to a remote receiving unit for monitoring by a health care professional or other machine.

Abstract: An infant respiratory monitor for alerting the supervisors of an infant when there is a lack of movement of the infant due to potential respiratory problems. The device comprises a housing having an attachment for clip for securing the housing to an infant. Respiratory monitoring circuitry is contained within the housing, and comprises a power source which is in circuit with a motion sensor, processor and audio output means. The motion sensor detects movement, and transmits the presence of such movement to the processor. The processor is configured to count the number of signals received from the motion sensor within a pre-determined time period and alert the sound output means in the event that the number of signals received within the pre-determined period of time from the motion sensor drops below a pre-determined value. Upon that occurrence, the processor signals the audio output means to emit an audible alert warning noise.

Abstract: A template has a flexible sheet with a fixed dimensional array V.sub.1 -V.sub.6 positioned in a specific size configuration appropriate for standard electrocardiographic recording.

Abstract: A method and apparatus (21, 150) is disclosed for identifying tissue which is suspected of being physiologically changed as a result of pre-cancerous or cancerous activity. The apparatus (21, 150) includes a probe (1, 10; 151) configured to contact the tissue and which includes an arrangement (3-7, 17-47; 158-163) to subject the tissue to a plurality of different stimuli such as electrical, light, heat, sound, magnetic and to detect plural physical responses to the stimuli. The probe (1, 10; 151) connects to an analogue section (23; 152) which buffers signals between the probe (1, 10; 151) and a processor (22; 153). The processor (22; 153) processes the responses in combination in order to categorise the tissue, and then compares the categorisation with a catalogue of expected tissue to identify the tissue, the processing occurring in real-time with an indication of the tissue type (eg. normal, pre-cancerous/cancerous, or unknown) being provided to an operator of the apparatus.

Abstract: The multi-purpose sensor includes a pair of arms, light-emitting device and light-receiving device that are fitted in an end portion of the arms, respectively, and electrodes that are made of an electrically conductive elastic material and which are bonded to end portion of the arms, respectively.
