Abstract
An adjustable height tool for locating a magnetically readable and settable valve which includes a wall having a first perimeter. A platform can be disposed within the first perimeter. A valve cut-out can disposed within the platform and receive at least a portion of the valve. A movable foot can be disposed below the platform by which a displacement element moves the foot at least one of toward or away from the platform, in fixed increments of about 1.5 mm, upon rotation of the displacement element. This movement increases or decreases the distance between the platform and the skin/valve.
Claims7
An adjustable height tool for locating a readable and settable valve, the locator comprising:
- a wall having a first perimeter;
- a platform disposed within the first perimeter;
- a valve cut-out disposed within the platform and receiving a portion of the valve;
- a movable foot disposed below the platform;
- and
- a displacement element configured to move the foot at least one of toward or away from the platform, upon rotation of the displacement element, and controlling the amount of the valve received in the valve cut-out;
- wherein the displacement element only permits movement of the foot in fixed increments of about 1.5 mm.
A method for locating a magnetically readable and settable valve using an adjustable height tool, the steps comprising:
- locating the valve;
- positioning a locator over the valve wherein the locator comprises a wall having a first perimeter, a platform disposed within the first perimeter, a valve cut-out disposed within the platform, a movable foot disposed below the platform, a displacement element configured to move the foot at least one of toward or away from the platform upon rotation of the displacement element, and two or more recesses disposed in the foot and aligned with the valve cut-out;
- adjusting the height of a foot of the locator by rotating the displacement element comprising the step of;
- limiting the displacement element to movement in increments of about 1.5 mm;
- and
- adjusting the valve with an adjustor.
