Abstract
The utility model relates to a medical device, in particular to a lung function measuring device, which comprises a body, a counter and an exhaling nozzle, wherein, the exhaling nozzle is inserted on the body; the body is connected with the counter through a data line. The utility model is characterized in that one end of the exhaling nozzle forms an ellipse shape, and the outside of the other end of the exhaling nozzle is provided with a convex ring, which is favorable for the clamping of the exhaling nozzle and the body, and preventing gas from leaking from the inserting position, so the purpose of accurate vital capacity measurement is achieved. As the structure is used, the utility model has the advantages of convenient use, reasonable structure, no gas leakage, accurate measurement, and the like.
Description
Technical field
This utility model relates to armarium, specifically a kind of pulmonary function measuring device.
Background technology
At present, be used to check that the instrument of pulmonary generally uses the pulmonary function measuring device, it comprises body, enumerator and the expiration mouth that is plugged on the body, body is connected with enumerator through data wire, chamber body is provided with air intake duct and return-air road, impeller is housed in air intake duct, and the impeller shaft linkage counter is during use, measured's mouth is aimed at the expiration mouth and is exhaled, gas drives the counter records vital capacity by body, is beneficial to medical personnel at the data on the enumerator, measures measured's pulmonary function situation, its deficiency is: the expiration mouth that is plugged on the body is cylindrical, be not inconsistent with people's the shape of the mouth as one speaks,, make the vital capacity of measuring inaccurate easily from the gas leakage of corners of the mouth both sides.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, to provide a kind of and conform to the shape of the mouth as one speaks, and is air tight, measure pulmonary function measuring device accurately.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of pulmonary function measuring device, comprise body, enumerator and be plugged on expiration mouth on the body, body is connected with enumerator through data wire, mouth one end ovalize is characterized in that exhaling, the other end outside is provided with bulge loop, help exhaling the engaging of mouth and body prevents that gas from spilling from splicing position, reaches and measures vital capacity purpose accurately.
This utility model has advantages such as easy to use, rational in infrastructure, air tight, that measurement is accurate owing to adopt said structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the front view of expiration mouth in this utility model.
Fig. 3 is the structural representation of the left view of Fig. 2.
Reference numeral: expiration mouth 1, body 2, enumerator 3, ellipse 4, bulge loop 5
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further specified:
A kind of pulmonary function measuring device, comprise body 2, enumerator 3 and be plugged on expiration mouth 1 on the body 2, body 2 is connected with enumerator 3 through data wire, mouth 1 one end ovalizes 4 is characterized in that exhaling, the other end outside is provided with bulge loop 5, help exhaling the engaging of mouth 1 and body 2 prevents that gas from spilling from splicing position, reaches and measures vital capacity purpose accurately.During use, one end that will have bulge loop 5 engages with body 2, oval 4 expiration mouths 1 are aimed at mouth, forced expiration, make the gas of exhalation can enter in the body 2 fully, make the data of measuring on the enumerator 3 can write down measured's vital capacity exactly, this utility model has advantages such as easy to use, rational in infrastructure, air tight, that measurement is accurate owing to adopt said structure.
