Abstract
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.
