The utility model belongs to the technical field of ocean buoy equipment, and discloses an intelligent air interchanger for a buoy. The device comprises a shaft; a hatch cover isolated from the outside is sealed at the top of the shaft; the shaft is fixed on the shaft shell; the shaft shell is fixedly connected with the instrument cabin; and an air exchange component is arranged at the inner upper part of the shaft, and the air exchange component is used for enabling air for sealing the shaft to obtain power under the action of wave energy, forcing the air in the instrument cabin to finish one-time air suction and exhaust air exchange work at each wave peak and wave valley along with the wave energy, and circularly exhausting humid air in the instrument cabin. An exhaust and suction passage is formed from the shaft to the mast barrel from bottom to top through wave energy, convection is formed inside and outside the buoy, temperature inside and outside the instrument cabin is exchanged in time, condensate water is reduced, and a reliable environment is provided for normal operation of equipment in the instrument cabin.

The application relates to the prefabricating processing technical field of a gas pipeline, in particular to prefabricating processing equipment and a process for a medical gas pipeline, which comprises an operation table, the outer wall of the top of the operation table is fixedly connected with a support frame, the outer wall of the top of the operation table is provided with a track groove, the inside of the track groove is slidably connected with a mounting plate one, and the outer wall of one side of the mounting plate one is rotatably connected with a fixing rod. Through the cooperation of the strip-shaped hole and the limiting rod, the mounting plate two can be driven to rotate when the rotating shaft two rotates, so that the grinding plate grinds the cutting surface of the medical gas pipeline, the cutting surface is polished, the inside of the medical gas pipeline can meet the relevant hygiene standards, a safe and reliable environment is provided for medical activities, burrs on the cutting surface of the medical gas pipeline are avoided, correspondingly, the smoothness and neatness of the cutting surface are improved, and the resistance to gas flow is reduced.

This utility model relates to a cervical spine support pillow for preventing displacement while lying supine. It includes a first pillow body that engages with the head; a second pillow body detachably positioned at the center of the upper side of the first pillow body to engage with the neck; and detachable limiting pillow bodies on the left and right sides of the second pillow body. A third pillow body detachably positioned on the front side of the first pillow body to engage with the shoulders. First fixing straps extend outward from the outer sides of the limiting pillow bodies, with hook-and-loop fasteners at their ends. A pair of second fixing straps are provided on the top and front surfaces of the left and right sides of the third pillow body, with hook-and-loop fasteners at their ends. It is simple to operate, convenient to use, and suitable for various patients.
