Abstract

The invention relates to the technical field of medical instruments, in particular to an intelligent probe patch for microscopy free flap blood supply monitoring, which comprises a disposable probe patch which is configured to be attached to the surface or the edge of a free flap, the bottom surface of a flexible substrate of the disposable probe patch is provided with a biocompatible adhesion layer, and the biocompatible adhesion layer is provided with a biocompatible cavity; an auxiliary structure for resisting postoperative tissue activity or secretions is arranged at the top of the flexible substrate; an optical sensing unit and a temperature sensing unit which are respectively used for acquiring local blood oxygen saturation, pulse rate and surface temperature of a flap are integrated in the disposable probe patch; the repeater establishes non-contact near-field coupling with the disposable probe patch, and the repeater is configured to provide working electric energy for the disposable probe patch through near-field coupling, so that the disposable probe patch works in a state without a built-in battery; physiological parameter data which are collected by the disposable probe patch and reflect the local microcirculation state of the skin flap are synchronously received; and the terminal equipment is in wireless communication connection with the repeater and is used for receiving and processing the physiological parameter data.
