Abstract

A placement device for a medical patch includes an alignment guide having a shaft with a first end having a first anatomical alignment marker and a second end having a second anatomical alignment marker, a swinging gate both pivotally and rotationally coupled with the first end of the shaft for selectively pivoting the gate toward and away from the shaft and rotating the gate between opposite sides of the shaft, whereby the gate has first and second major faces and a first opening extending through the gate between the first and second major faces. The placement device includes a spacer for selectively adjusting spacing between the gate and the first end of the shaft, and a flexible diaphragm having a flexible dome disposed within the first gate opening. At least one magnet is located in the center of the flexible dome for holding the medical patch within the flexible dome.
