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.

Tonometer mounting device

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.
