Description

Vital capacity measuring device

Technical field

This utility model relates to medical instruments field, especially a kind of vital capacity measuring device device.

Background technology

Vital capacity refers to when in unlimited time, and do one's best after a maximum inhale breathed out gas flow again, and this represents the once maximum functional activity amount of lung, is one of important function criterion of reflection growth in humans developmental level." national student physical health standard " requirement, vital capacity is primary school five, six grades and junior middle school, senior middle school, the each classman of university must survey project, it can thus be appreciated that, in the sports curriculum of school in China, vital capacity test is all required course, and also count in the test of urban vital capacity the project examined in physical culture, and a large amount of vital capacity measuring devices in school, certainly will be had, if all adopt the tester that precision instrument manufactures, concerning school being a huge expense, therefore majority is all fairly simple tester, the floating drum class testing instrument such as, tested after adopting water, and the fan blade tester etc. of similar windmill class, and floating drum class testing instrument must realize pouring water, student carries difficulty, when many people use simultaneously, sanitary condition causes anxiety, and carrying is convenient in just comparing of windmill class, smaller and more exquisite, the such as patent No. " 03206715.1 whistle shaped spirometer " and " 201220272913.5 small-sized spirometer " these two testers, all achieve small and exquisite easy-to-use object, but in actual use, still a series of problem is still had, user is in air blowing, during air-breathing, fan blade can both be driven to rotate, the numerical value of such enumerator is just inaccurate, especially in the important events such as to examine, definitely can not occur, and when user is blown, saliva will certainly be blown into, and the photoelectric reactor in " small-sized spirometer " is just easy to make moist, service life is not long, simultaneously, the tester of these two Patent designs, all there is saliva not easily to discharge, and inside is not easy problems such as cleaning, the problem that is used alone at home is little, but when the situation that the school many people of a this machine use, sanitary condition is just difficult to ensure that.

Summary of the invention

The purpose of this utility model is, provide a kind of simple and reasonable, easy to use, be convenient for carrying, accurately can test vital capacity simultaneously, be convenient to collect saliva, vital capacity measuring device convenient for cleaning, to overcome the deficiency of prior art.

This utility model realizes its object technical scheme:

A kind of vital capacity measuring device, comprise air inlet, gas outlet, fan blade, travelling gear and housing, housing have air inlet and gas outlet, fan blade and travelling gear are installed in shell cavity, and fan blade coordinates with travelling gear transmission, described housing comprises upper cover and lower house, the sidewall of lower house has fitting recess, the sidewall of upper cover has the tappet matched with fitting recess, on cover and have air inlet, the fan blade corresponding with the position of air inlet is installed in lower house, also there is connecting rod in lower house, one end of connecting rod has the travelling gear coordinated that to move with fan blade, the other end of connecting rod is connected with the enumerator on lower house outer surface, travelling gear realizes telecommunication by holding wire and enumerator and is connected, described air inlet place has the first check valve, gas outlet place has the second check valve, the end of air inlet is provided with blow gun, the inner chamber of blow gun is provided with permeable membrane, the end of gas outlet is provided with fluid collection casette, the sidewall of fluid collection casette has some air-vents.
