Description
Technical field
The utility model belongs to technical field of medical, relates in particular to a kind of medical breath detection device.
Background technology
The uncommon ripple of ancient Greek undercuts the epoch, and doctors come the auxiliary diagnosis disease with regard to knowing the smell by detecting patient exhales.In the France in 18th century, the pioneer of Antoine Lavoisier-modern chemical analysis, he is that first analyzes expiration, proves that it contains carbon dioxide.Modern breath tester starts from 1971, and Nobel chemistry Prize winner Linus ripple woods finds that the human normal concentration that comprises many different volatile organic compounds of exhaling is very low.But, these technology are just used by indivedual experts at present, also be not widely applied in the medical practice, this is because the organism kinds in detect exhaling and the variation of quantity can only manually be finished by experienced expert, so just makes that this expiration testing cost is high, process is complicated, the time is very long, out of true as a result.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of testing cost is lower, process is simple, the time is short, the result is accurate, widely used medical breath detection device.
The technical scheme that addresses the above problem is: this medical breath detection device, it comprises injection port, sampling pump, six-way valve, carrier gas bottle, adsorption tube, chromatographic column, surface acoustic wave detecting device, data handling system, six-way valve connects second end, the sampling pump of first end, the adsorption tube of injection port, carrier gas bottle, adsorption tube, an end of chromatographic column respectively, the other end of chromatographic column connects the surface acoustic wave detecting device, and the output terminal of surface acoustic wave detecting device inserts data handling system.
During sampling, injection port connects first end of adsorption tube, adopts pump to connect second end of adsorption tube, and carrier gas bottle connects chromatographic column, and the expiration sample is inhaled into injection port by sampling pump, enters adsorption tube and is adsorbed at this via six-way valve; Injection port connects sampling pump during analysis, carrier gas bottle connects first end of adsorption tube, second end of adsorption tube connects chromatographic column, adsorption tube heating, sample desorption, brought into chromatographic column by the carrier gas in the carrier gas bottle and separate, separating the different material in back can flow out from chromatographic column successively, arrives the surface acoustic wave detecting device then, and the surface acoustic wave detecting device detects frequency change, record these variations, after data-switching, obtain chromatogram; Utilize data handling system that chromatogram is handled and obtain comparing result; Testing cost is lower like this, process is simple, the time is short, the result is accurate, be widely used.
Description of drawings
Structural representation when Fig. 1 is preferred embodiment sampling of medical breath detection device of the present utility model;
Fig. 2 is the structural representation of preferred embodiment of medical breath detection device of the present utility model when analyzing.
Embodiment
We know now, and sample normal person's expiration comprises usually and surpasses 200 different volatile organic compounds, and wherein great majority are in picomole (Pico molar) concentration.The kind of these compounds and content, metabolic closely bound up with in the body.When (pathology) when unusual, the variation that will produce new compound or existing compound generating capacity in the body appear in part organ in the body.Detect these organism kinds in exhaling and the variation of amount, according to the way of artificial neural network isotype identification, we can make diagnosis to disease (for example in lung cancer, pulmonary tuberculosis, breast cancer, the organ transplant body rejection etc.).
Be example with lung cancer.
Lung cancer is one of modal malignant tumour in the world at present, accounts for 16% of whole malignant tumours, 28% of malignant tumour death.At present, only 14.1%, 60% patient is dead in back 1 year of diagnosis for 5 years survival rates of patient diagnosed.Means such as the triage techniques of tradition lung cancer such as X line, phlegm inspection, Bronchofiberscope can not reduce screened crowd's lung cancer mortality.Testing process is comparatively loaded down with trivial details, and the time is longer, dynamic monitoring in early days and being restricted.Advanced technologies such as new technology such as spiral CT, positron emission imaging, molecule damage check technology be applied to the lung cancer early diagnosis and by stages, dynamic monitoring state of an illness aspect obtains certain progress.But because of its expense costliness, methodology complexity, the technical requirement height is difficult at present as conventional lung cancer early diagnosis and dynamic monitoring means.
Shown in Fig. 1-2, applicant's this medical breath detection device, it comprises injection port 1, sampling pump 5, six-way valve 2, carrier gas bottle 3, adsorption tube 4, chromatographic column 6, surface acoustic wave detecting device 7, data handling system 8, six-way valve connects second end, the sampling pump of first end, the adsorption tube of injection port, carrier gas bottle, adsorption tube, an end of chromatographic column respectively, the other end of chromatographic column connects the surface acoustic wave detecting device, and the output terminal of surface acoustic wave detecting device inserts data handling system.
During sampling, injection port connects first end of adsorption tube, adopts pump to connect second end of adsorption tube, and carrier gas bottle connects chromatographic column, and the expiration sample is inhaled into injection port by sampling pump, enters adsorption tube and is adsorbed at this via six-way valve; Injection port connects sampling pump during analysis, carrier gas bottle connects first end of adsorption tube, second end of adsorption tube connects chromatographic column, adsorption tube heating, sample desorption, brought into chromatographic column by the carrier gas in the carrier gas bottle and separate, separating the different material in back can flow out from chromatographic column successively, arrives the surface acoustic wave detecting device then, and the surface acoustic wave detecting device detects frequency change, record these variations, after data-switching, obtain chromatogram; Utilize data handling system that chromatogram is handled and obtain comparing result; Testing cost is lower like this, process is simple, the time is short, the result is accurate, be widely used.
Preferably, described carrier gas bottle 3 is inert gas carrier gas bottles, for example helium tank, nitrogen cylinder, argon bottle etc.
