aerophore

1. (botany) A thin-walled area of the roots of some plants growing in swampy conditions through which gasses are exchanged.Examples: "Segments with more than 25 pairs of veins; indusium minute, ciliate. soon disappearing; a linear-attenuate brown aerophore present at base of each pinna 16."; "In most species the dorsolateral aerophore line is conspicuous throughout the length of the stipe, generally being somewhat paler in colour than the surrounding tissue."

2. (medicine) Aerophore pulmonaire; a respirator for use with neonates and small animals developed by French obstetrician Gairal in 1879.Examples: "The Aerophore was attached as soon as respiration ceased and was continued for three minutes at which time the animal began to breathe spontaneously."; "The first apparatus used for intermittent positive pressure ventilation was the “aerophore pulmonaire,” developed by French obstetrician Gairal and made known to the public in 1897."; "The mouths and noses of the rats were covered with an aerophore to allow them to breathe in the water."

3. (historical) A predecessor of the radio, invented by Rene Homer in the early 1900s for communication between ships.Examples: "The aerophore will be placed in operation some time during the coming season by the Great Lakes Radio Telephone Company, in conjunction with the wireless telephone."; "The wheel Q is also provided with frequently-recurring contacts T, which are different for each transmitting-device or “aerophore,” in order to indicate the location of the aerophore from which the direction signals are transmitted."; "The shaft of the aerophore's searchlight might represent the gun barrel, and the Hertzian waves, bearing the message, the bullet."historical

4. (historical) A nineteenth-century device with breathing tubes used by miners and workmen in areas that contain toxic fumes.Examples: "The aerophore consists of a number of large or small cylinders as desired, which are lowered into the place with the workman. Connected with the cylinders is a long flexible tube almoast an inch in diameter of such strength that it cannot be damaged even by being trod upon."; "The aerophore, a new life-saving apparatus, is at present attracting much attention. It is specially designed to enable the workman or miner to enter a mine full of fire-damp, and to labor there with complete immunity from danger."; "For antiexplosion, special tools must be taken, and maintenance workers generally need to be armed with exposure suit and aerophore, otherwise it can be harmful to their skin, eyes and respiratory system and even lead to fatal accidents."historical

Their creation is considered the source of modern scuba equipment."; "The aerophore consisted of two main components — an air-filled canister about the size and shape of a lawn mower engine, which the diver wore on his back, and a new creation, a "regulator," which automatically adjusted the pressure of the air in the tank to that of the water surrounding it."historical
