Device for, and a method of, transcutaneous pressure waveform sensing of an artery and a related target apparatus
First Claim
1. A device for transcutaneous pressure waveform sensing of an artery, the device having, in use, an application direction towards the skin of a user in the direction of an underlying artery and including:
- a pressure sensing head having a distal end; and
at least one skin depressing means substantially adjacent the pressure sensing head and having a distal surface, wherein the pressure sensing head distal end and skin depressing means distal surface(s) are sized such that the pressure sensing head distal end is spaced apart, in the application direction, from the skin depressing means distal surface(s).

Abstract
A device (20) for transcutaneous pressure waveform sensing of an artery. The device (20) having, in use, an application direction (43) towards the skin (46) of a user. The device (20) includes a pressure sensing head (37) having a distal end (36) and at least one skin depressing means (38) extending at least partially around the head (37) and having a distal surface (40). The pressure sensing head distal end (36) and skin depressing means distal surface(s) (40) are sized such that the pressure sensing head distal end (36) is spaced apart, in the application direction, from the skin depressing means distal surface(s) (40). A method of transcutaneous pressure waveform sensing and a target apparatus (100) are also disclosed.

17. A method of transcutaneous pressure waveform sensing of an artery, the method including the steps of:
-
flattening and depressing at least some of the skin around the and displacing same, in an application direction towards the artery, to a first depth; and
flattening and depressing the skin over the artery and displacing same, in the application direction, to a second depth that differs than the first depth. - View Dependent Claims (18, 19, 20, 22, 23, 24, 25, 26, 27, 28)

29. A target apparatus for use with a device for transcutaneous waveform pressure sensing of an artery, the device having an end with a pressure sensing head protruding therefrom, the apparatus including:
-
an skin adhesive pad;
a target marking on the pad; and
skin compression means at least partially around the target marking, wherein, during use, the device is applied to the pad with the device pressure sensing head over the target marking and the device end over the skin compression means whereby, when the device is depressed into the skin during use, the skin beneath the target marking and the skin compression means are displaced to differing depths. - View Dependent Claims (30, 31)
