摘要： A device for mounting a tonometry sensor upon a patient's wrist includes a base portion that is specifically adapted to generally conform to the patient's wrist while providing a stable placement of the tonometry sensor relative to a preselected artery. A sensor housing is movably mounted upon the base portion and configured such that the mounting device has an essentially equal thickness at each end of the device. A strap member is provided for releasably securing the mounting device to a patient's wrist. The mounting device facilitates more accurate, non-invasive blood pressure measurement by providing a stable placement of the tonometry sensor relative to the tissue overlying a preselected artery at a measurement location and, further, limits undesirable movement by the patient to thereby reduce undesirable error in the blood pressure measurement.

摘要： A wrist mount apparatus for placing a tissue stress sensor in operative engagement with the tissue overlaying an artery of interest is disclosed for use in a system for noninvasively determining the intra-arterial blood pressure of a patient. The wrist mount apparatus comprises a base portion and a transducer platform which is pivotally and slidingly engaged to the base portion. This arrangement allows the apparatus to be used on either the right or the left wrist of the wearer. A force overload system is provided whereby the wearer is protected from excessive forces applied to the wrist tissue by the apparatus used to applanate the artery. A quick disconnect feature allows the tissue stress sensor to be removed from the wrist mount apparatus without necessitating the use of tools. A disposable, anticontamination film is used with each application of the wrist mount apparatus to minimize the risk of transferring contaminants from one wearer to another and to prevent a build up of materials on the sensor's face.

摘要： A system for noninvasively continuously monitoring arterial blood pressure includes a tissue stress sensor that has a continuous diaphragm for sensing stress within tissue adjacent a preselected artery caused by arterial pulsations within that artery. The stress sensitive diaphragm is coupled with electromechanical means for producing electrical signals that represent the stress within the tissue that is communicated to the sensor. These signals are then processed electronically in order to yield an output that is indicative of the arterial blood pressure of the preselected artery. The disclosed system includes methods of operation for determining blood pressure while maintaining a preselected artery in an optimum applanation state and an off-optimum applanation state.

摘要： A method, for use in a non-invasive blood pressure monitoring system, of determining which portion of a stress sensitive element of a tissue stress sensor is best located for detecting the stress of tissue overlying an artery of interest. The tissue stress sensor is placed in communication with tissue overlying the artery of interest and a plurality of electrical signals are obtained therefrom representing stress data across the length of the stress sensitive element. Each electrical signal represents stress datum communicated to a predetermined portion of the stress sensitive element. From the stress datum, a centroid of energy is computed and the centroid of energy is used to determine which portion of the stress sensitive element is best located for determining the blood pressure within the artery of interest. A second method is disclosed which uses the centroid of a tissue foundation flexibility function to determine the best location along the stress sensitive element for determining blood pressure.

摘要： A method, for use in a non-invasive blood pressure monitoring system, of determining optimum artery applanation. The system uses a stress sensor including a stress sensitive element for detecting stress of tissue overlying an artery of interest. The tissue stress sensor is placed in communication with tissue overlying the artery of interest and at least one electrical signal is obtained therefrom representing stress data across the length of the stress sensitive element. The data represents stress datum communicated to a preselected portion of the stress sensitive element. From the stress datum, various algorithms are used, singly or in combination, to provide the best measure of optimum applanation state. Intra-arterial blood pressure is then calculated using datum collected at the optimum applanation state. In addition, to the optimum applanation methods, a method is disclosed for determining which portion of the stress sensitive element is best suited for estimating intra-arterial blood pressure.

摘要： A method, for use in a non-invasive blood pressure monitoring system, of operating a tissue stress sensor at an off-optimum arterial applanation state. The system uses a stress sensor including a stress sensitive element for detecting stress of tissue overlying an artery of interest. The tissue stress sensor is placed in communication with tissue overlying the artery of interest and at least one electrical signal is obtained therefrom representing stress data across the length of the stress sensitive element. The data represents stress datum communicated to preselected portions of the stress sensitive element. From the stress datum, various techniques are used to determine the optimum applanation state and the actual applanation state. A waveform scaling factor function is created which compensates for the errors associated with operating the tissue stress sensor at an off-optimum applanation state. Thus, the disclosed method provides the benefits associated with operating a tissue stress sensor at an off-optimum state without sacrificing measurement accuracy.

摘要： An artery applanation actuator for use in a system for noninvasively determining the intra-arterial blood pressure of a user incorporates a fluid actuator to effect movement of a sensor. The movement of the sensor is effective for applanating an artery of interest and measuring the stress of the tissue overlaying the artery of interest. Alternative embodiments of the artery applanation actuator are presented wherein an electric motor is used to activate a rotating arm which has a sensor located thereon. The rotation of the arm causes the sensor to contact and press against the tissue overlying the artery of interest. The artery applanation actuator is presented having a protective sheath surrounding the sensor to protect the sensor against inadvertent contact.
