The technical field is as follows:

The invention relates to a medical test tool, in particular to a device used in a candle blowing test.

Background art:

chinese smokers who smoke about 3.5 hundred million cigarettes exist, and long-term smoking can cause lung function damage of patients, particularly patients suffering from chronic obstructive pulmonary disease, the lung function is gradually reduced, and pulmonary function instrument examination is important examination equipment for evaluating the lung function condition of the patients, but the patients need good matching degree, particularly the patients with large age, language communication disorder and comprehension deviation, and the high-quality lung function examination is very difficult to complete, and the evaluation of the lung function of the patients is seriously influenced. The candle blowing test is a relatively simple examination method, is an easy-to-understand, simple and easy-to-implement examination method for examining the respiratory function of a patient by a respiratory physician, and can roughly understand the pulmonary function and respiratory muscle function conditions of the patient by measuring the distance of blowing out the candle. The traditional inspection method is to place lighted candles at unequal distances on a table, and measure the distance of the last blown candle as the value of the tester's candle blowing test. There are studies reporting that a candle that is 1.2 meters away can be blown out when the organism is 20 years old; the candle with the distance of 1.0 meter can be blown out when the living beings are 30 years old; the candle with the distance of 0.8 m can be blown out when the living beings are aged 40 years; the candle with the distance of 0.7 m can be blown out when the living beings are 50 years old; the biological age of 60 can only blow out candles with the distance less than 0.7 meter, and the distance for blowing out candles is shorter and shorter with the age. The candle blowing distances of patients of different ages and even patients with different diseases in the same age are different, so that the lung function and respiratory muscle function conditions of the patients are reflected.

the traditional inspection method has obvious defects, and firstly, a set of fixed and formed candle blowing test device is lacked for clinical use; secondly, the air flow needed for blowing out the last candle is easily influenced by the blockage of the front candle; thirdly, measuring the distance for blowing out the candle by using a meter ruler; fourthly, the distance for blowing out the candle is influenced by different blowing air flow angles; fifthly, the candle extinguishes and is easily influenced by peripheral airflow except for blowing airflow. In order to overcome the defects, the candle blowing test device is specially designed, the defects are solved, and a set of candle blowing test device which is simple, convenient and feasible and is convenient to operate is provided for clinic.

The current patent technical data, patent ZL201420740572.9 design are one kind and blow the candle device, just start the device that the fan extinguishes the candle through microphone sensor, can not detect the distance of blowing out the candle, also can't judge and know patient's lung function and respiratory muscle function. Clinically, a test tool which has strong operability, is simple and easy to operate and can directly judge the distance of the blown candle is needed.
