Wrist mount apparatus for use in blood pressure tonometry
First Claim
1. A wrist mount apparatus for mounting a tissue stress transducer on either wrist of a wearer in operative engagement with the tissue overlying an artery of interest, said artery including a longitudinal axis along its length, said wrist mount apparatus comprising:
- wrist mount means for grasping a wrist of said wearer in proximity to the said artery of interest,a base portion coupled to said wrist mount means,a transducer platform including means for housing said tissue stress transducer,parallel coupling means including a first end connected to said transducer platform and second end cooperatively engaged to said base portion for moving said transducer platform between first and second positions generally parallel to said longitudinal axis of said artery of interest,whereby said wrist mount apparatus is adapted to mount to the right wrist of the wearer, and said parallel coupling means is operative for moving said transducer platform generally parallel to said longitudinal axis of said artery into said first position, thereby enabling said transducer platform to place said tissue stress sensor into operative engagement with the tissue overlying an artery of interest in said wearer'"'"'s right wrist, andwhereby said wrist mount apparatus is adapted to mount to the left wrist of the wearer, and said parallel coupling means is operative for moving said transducer platform generally parallel to said longitudinal axis of said artery into said second position thereby enabling said transducer platform to place said tissue stress sensor into operative engagement with the tissue overlying an artery of interest in said wearer'"'"'s left wrist,whereby said apparatus is adapted for use on the right or left wrist of the wearer.

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.

12. A wrist mount apparatus for placing a tissue stress transducer in operative engagement with the tissue overlying an artery of interest, said wrist mount apparatus comprising:
-
a base portion including means for mounting said base portion to the wrist of the wearer, a transducer platform including means for housing said tissue stress transducer, said transducer platform including means for movably engaging said transducer platform to said base portion, forcing means, coupled to said transducer platform and including means for engaging said tissue stress transducer, for forcing said tissue stress transducer into operative engagement with said tissue overlying said artery of interest, force sensing means, coupled between and sensitive to a force between said base portion and said transducer platform, for allowing said transducer platform to move away from said base portion thereby releasing said tissue stress transducer from operative engagement with said tissue overlying said artery of interest whenever said force of said tissue stress transducer against the tissue of the wearer exceeds a predetermined value. - View Dependent Claims (13, 14)

15. A wrist mount apparatus for placing a tissue stress transducer in operative engagement with the tissue overlying an artery of interest, said wrist mount apparatus comprising:
-
a base portion including means for mounting said base portion to the wrist of the wearer, a transducer platform including means for engaging said tissue stress transducer, quick disconnect means for connecting said transducer platform to said base portion, whereby said disconnect means allows said transducer platform and said tissue stress sensor to be quickly removed from said base portion, wherein said quick disconnect means includes a coupling member fastened to said base portion, wherein said coupling member includes a lipped portion and said transducer platform includes a recessed portion, wherein said lipped portion cooperatively engages and retains said recessed portion, wherein said coupling member includes a retaining pin and said transducer platform includes a receiving cavity, said retaining pin positioned on said coupling member to be received within said receiving cavity as said lipped portion of said coupling member is slidingly engaged with and retained within said recessed portion of said transducer platform. - View Dependent Claims (16, 17)
