This invention relates to the field of
medical device technology, and more particularly to an intelligent probe patch for monitoring
blood circulation in microscopic free flaps, comprising: a disposable probe patch configured to be attached to the surface or edge of the
free flap; a biocompatible
adhesive layer is provided on the bottom surface of the flexible base of the disposable probe patch, and an auxiliary structure is provided on the top of the flexible base to
resist postoperative tissue activity or secretions; the disposable probe patch integrates an
optical sensing unit and a
temperature sensing unit for collecting local blood
oxygen saturation,
pulse rate, and surface temperature of the flap, respectively; a
repeater, establishing non-contact near-field
coupling with the disposable probe patch, the
repeater being configured to provide working power to the disposable probe patch through near-field
coupling, enabling it to operate without a built-in battery; and synchronously receiving physiological parameter data reflecting the local
microcirculation status of the flap collected by the disposable probe patch; and a terminal device, wirelessly connected to the
repeater, receiving and
processing the physiological parameter data.
