The invention relates to a high-flow temperature and humidity oxygen therapy joint for a tracheotomy patient, which comprises a corrugated connecting pipe, one end of the corrugated connecting pipe is provided with a first quick plug for connecting a high-flow temperature and humidity oxygen output pipe, and the other end of the corrugated connecting pipe is connected with a straight pipe; a second quick plug connected with a trachea cannula is arranged at one end of the straight pipe, and an exhaust hood is arranged at the other end of the straight pipe; an opening is formed in the exhaust hood, an annular cavity is formed in the periphery of the opening, the four edges of a movable rod plate are arranged in the annular cavity in a sliding mode, the center of the movable plate is rotationally connected with a turning cover, and a plurality of exhaust holes are formed in the turning cover in an array mode. A V-shaped elastic piece is further fixed to the movable plate, and the free end of the V-shaped elastic piece abuts against the end, away from the rotating shaft of the turning cover, of the turning cover so that the turning cover can keep the closing tendency in the natural state.

The invention discloses a tumor microwave heating device, and belongs to the technical field of biomedical engineering and microwave thermal therapy. The device includes a microwave heat source, a near field metasurface lens (MSL), and a dielectric anti-reflection layer (AR). The MSL is composed of a plurality of four-layer metal-medium sub-wavelength units which are distributed according to a hyperbolic phase and used for focusing microwave energy to a deep tumor target region in a biological tissue under the working frequency of 3 GHz; the AR layer is arranged between the MSL and the tissue, is designed based on a quarter wavelength conversion principle and is used for matching impedance of air and multi-layer biological tissue (skin / fat / muscle). Through the synergistic effect of MSL and AR, the device significantly reduces interface reflection (about 35 dB), and realizes highly localized energy deposition in a tumor area, so that the average specific absorption rate (SAR) is improved by 9.7 times, and the efficiency, precision and safety of microwave hyperthermia are greatly improved.
