NON-INVASIVE FETAL PROBE HAVING IMPROVED MECHANICAL AND ELECTRICAL PROPERTIES

摘要

A non-invasive fetal probe having enhanced adhesion and electrical isolation for attaching to the presenting part of a fetus and sensing at least one fetal parameter during labor and delivery. In one embodiment of the present invention, the electrical isolation of the fetal probe includes a non-conductive element used in combination with various conductive assemblies made from gel formulations which are polymerized to form a fetal sensor. The non-conductive element in addition to providing physical separation also enhances electrical separation between fetal and maternal sensing elements of the fetal probe. Non-invasive fetal probes having low-profile designs are also provided which help decrease the tendency of the fetal probes to detach caused by forces generated upon the probe by the head of the fetus, the cervix of the mother, or both.
