Abstract

The invention discloses a glass cylinder vital capacity and vital power resisting test instrument. Two vital capacity and vital power test instruments are connected through a pipe. A valve is arranged on the pipe, and a glass cylinder for holding table tennis is connected in parallel with the valve. Each vital capacity and vital power test instrument comprises a buoy and a water tank, and the buoys are arranged in the water tanks. Air inlet nozzles in the bottoms of the water tanks are connected with air blowing nozzles through hoses. Buoy rods with scales are inserted into the water tanks from rod sleeves with seal rings to be inserted into the buoys after passing through buoy valve seats, and valve plates are arranged at the ends. Springs are arranged at the connection positions between rods with seal rings and the buoy valve seats to compress the buoy valve seats to form seals. Exhaust valves and water inlet units are arranged above the water tanks, and liquid level meters with scales are connected with the sides. By means of the test instrument, the structure is simple and reliable, opening and closing are achieved through cams and are convenient and reliable to operate; tensioning and reset is achieved through springs, and the cost is low; gas leakage can be prevented effectively through seal pads; vital capacity and vital power measuring can be performed, vital capacity and vital power resisting test can be performed, high entertainment is provided, and the application prospect is broad.

Description

technical field [0001] The invention relates to a glass cylinder type lung capacity and lung power resistance tester. Background technique [0002] Spirometry test is one of the important test items for health screening and physical examination. Spirometry and lung power test can reflect the cardiopulmonary function, while lung capacity and lung power confrontation test can compare the strength of the opponent's cardiopulmonary function, and it also has a strong entertainment sex. [0003] Testers for measuring lung capacity and lung power have been sold on the market, but no special lung capacity and lung power resistance tester has been seen. The existing lung capacity and lung power testers still have many unsatisfactory places, such as lung power Convenient switching between test and lung capacity test, further optimization and simplification of instrument operation and internal structure, improved service life, convenience of reset operation, etc., optimize and upgrade...
