Description

A kind of medical experimental rig that blows at a candle

Technical field:

The utility model relates to a kind of medical experiment tools, and in particular to blow at a candle and test used device.

Background technique:

There is the smoker of about 3.5 hundred million smokings in China, and long-term smoking can cause Pulmonary Function to damage, especially with slow Property obstructive disease of lung patient, lung function in progressive decline, lung function instrument inspection be assess Pulmonary Function situation it is important It checks equipment, but needs the good degree of cooperation of patient, especially older, IMPAIRED VERBAL COMMUNICATION, understandability deviation Patient, the pulmonary function test for completing a high quality are extremely difficult, seriously affect the evaluation of Pulmonary Function.The test that blows at a candle is A kind of relatively simple inspection method, be Respiratory Medicine doctor check breath function due one kind be readily appreciated that, be simple and easy, Easy to operate inspection method can substantially understand the lung function and respiratory muscle function of patient by measuring the distance to puff the candle out Situation.Traditional inspection method is that equal distance does not place the candle lighted on the table, measures last and is puffed the candle out Distance, blow at a candle the numerical value of test as tester.Studies have reported that biological age 20 years old when, can blow out 1.2 meters of distance Candle；1.0 meters of distance of candle can be blown out at biological age 30 years old；0.8 meter of distance can be blown out at biological age 40 years old Candle；0.7 meter of distance of candle can be blown out at biological age 50 years old；It is only capable of blowing out distance at biological age 60 years old less than 0.7 The candle of rice, the distance to puff the candle out with advancing age also can be shorter and shorter.Even different age group, same age bracket The distance that the different patient of illnesses puffs the candle out also is not quite similar, to reflect the lung function and respiratory muscle function of patient Situation.

It is significant insufficient that traditional inspection method has it, first, lacking a set of fixed-type experimental rig confession that blows at a candle Clinical use；It is easy to be influenced by the blocking of front candle second, blowing out air-flow required for last candle；Third, needing Make that the distance to puff the candle out is measured with meter scale；Fourth, the distance that inflatable gas flow angle Different Effects puff the candle out；Fifth, candle Extinguishing in addition to air blowing air-flow, be easy influenced by peripheral gas flow.To overcome the above deficiency, ad hoc one kind of counting blows at a candle test dress It sets, solves above-mentioned deficiency, provide a set of simple and easy to do, easy to operate experimental rig that blows at a candle for clinic.

Existing patented technology data, patent ZL201420740572.9 design are that one kind blows at a candle device, are only through Microphone sensor start blower extinguishing candles a kind of device, the distance to puff the candle out cannot be detected, can not also judge and Solve the lung function and respiratory muscle function of patient.Clinically need a kind of strong operability, it is simple and easy to do and can directly judge to blow out The test instrument of candle distance.
