Claim 5:
6. A method of anchoring a fetal heart transducer to the skin surface of an expectant mother comprising the steps of:
providing a strip of elastic material having a length, and having incremental openings along the length thereof, the strip having first and second ends;
providing first and second securing devices, each device comprising a body having a first surface and a second surface, the first surface having adhesive thereon, and a protuberance extending outwardly from the second surface in a direction opposed to the first surface, the protuberance to be received by one of the incremental openings along the length of the strip;
providing a fetal heart transducer having a first skin contacting transducer surface and a second transducer surface opposed to the first skin contacting transducer surface;
providing a wedge attachment having a wedge base, a wedge body and a wedge button, the wedge body having a sinusoidal profile in both front and side aspects, the wedge button being disc shaped and located at the top of the wedge body, the wedge button sized to be received into at least one of the incremental openings along the length of the strip,
determining the desired position of the fetal heart transducer;
positioning the first securing device at a first location adjacent to the desired position of the fetal heart transducer by placing the first surface of the first securing device against the skin surface of the expectant mother thereby affixing the first securing device in place;
positioning the second securing device at a second location adjacent to the desired position of the fetal heart transducer and opposed to the position of the first securing device, the positioning occurring by placing the first surface of the second securing device against the skin surface of the expectant mother thereby affixing the first securing device in place;
causing an incremental opening at the first end of the strip to be received into the protuberance of the first securing device;
causing an incremental opening at the second end of the strip to be received into the protuberance of the second securing device;
positioning the fetal heart transducer beneath the strip so that the first skin contacting transducer surface is adjacent to the skin surface of the expectant mother; and
positioning the wedge base on the second transducer surface and causing the wedge button to be received into one of the incremental openings along the strip, whereby the first skin contacting transducer surface remains adjacent and angled at least 10° from the horizon and adjacent to the skin surface of the expectant mother.
