Problems solved by technology

[0003] However, for the real-time enrichment of human exhaled breath, the current solid-phase extraction technology cannot directly sample the gas in real time. Solid-phase extraction needs to enrich the collected samples through the headspace, such as using gas sampling bags and gas sampling bottles to collect Oral and nasal exhalation, etc., and then put the solid-phase microextraction module into the gas collection device for enrichment, the operation is cumbersome and time-consuming

Embodiment 1

[0039] Use the device of the present invention to collect and absorb the exhalation of the human body after 10 minutes of drinking coffee, and detect the residue of oral exhalation. The specific method is as follows:

[0040] Step 1: The person under test drinks 200ml of coffee, and after ten minutes, put the prepared solid-phase adsorption module 4 on the holder 3, and put the mask body on the face of the person;

[0041] Step 2: Enrich the exhaled matter of the human body. The exhaled matter in the space area in front of the mouth and nose on the inner side of the mask piece 2 is enriched by the solid phase adsorption module 4. After 2 hours of enrichment, the solid phase adsorption module 4 is taken out for direct real-time mass spectrometry analyze;

[0042] Step 3: Detect human exhaled matter, take out the solid-phase adsorption module 4 and couple it with the analytical instrument, decompose and adsorb the analyte, measure the composition and content of the adsorbed samp...

Embodiment 2

[0045] Use the device of the present invention to collect and absorb the breath after the human body smokes for 10 seconds, and perform the detection of oral breath residues. The specific method is as follows:

[0046] Step 1: After the subject smokes for ten seconds, insert the prepared solid-phase adsorption module 4 into the holder 3, arrange the position of the solid-phase adsorption module 4, and put the mask body on the human face;

[0047] Step 2: Enrich the exhaled matter of the human body. The exhaled matter is enriched by the solid-phase adsorption module 4 in the space area in front of the mouth and nose on the inner side of the mask piece 2. After 2 hours of enrichment, the solid-phase adsorption module 4 is taken out for direct real-time mass spectrometry analysis ;

[0048] Step 3: Detect human exhaled matter, take out the solid-phase adsorption module 4 and couple it with the analytical instrument, decompose and adsorb the analyte, measure the composition and co...

Embodiment 3

[0051] Use the device nasal cavity of the present invention to spray the exhaled air after 10 minutes into the trace xylomedazoline aerosol to collect and absorb, and carry out the detection of nasal cavity exhaled residues, the specific method is as follows:

[0052] Step 1: Spray a small amount of Xolozoline aerosol into the nasal cavity of the tested person. After ten minutes, insert the prepared solid-phase adsorption module 4 into the holder 3. After finishing the position of the solid-phase adsorption module 4, put the mask body worn on the face of the human body;

[0053] Step 2: Enrich the exhaled matter of the human body. The exhaled matter is enriched by the solid-phase adsorption module 4 in the space area in front of the mouth and nose on the inner side of the mask piece 2. After 2 hours of enrichment, the solid-phase adsorption module 4 is taken out for direct real-time mass spectrometry analysis ;

[0054] Step 3: Detect human exhaled matter, take out the solid-ph...

Abstract

The invention discloses a wearable human exhaled matter adsorption device comprising a mask body. Mask belts are arranged on the two sides of the mask body; a mask sheet is connected between the two mask belts; a fixer is arranged in the mask sheet; and the fixer is used for fixing a solid-phase adsorption module. According to the invention, the wearable mask is used as a supporting body of the solid-phase adsorption module; the solid-phase adsorption module is used for effectively collecting and adsorbing mouth and nose exhales and effectively detecting the mouth and nose exhales; the mode that gas cannot be directly sampled in real time and operation is tedious and time-consuming in the solid-phase extraction technology is broken through, enrichment and analysis of exhaled gas in the mask are achieved, and physiological and pathological information of the human body is obtained by analyzing collected components of the exhaled gas of the human body.

Description

technical field [0001] The invention relates to the technical field of enrichment device and analysis of human exhalation, in particular to a wearable adsorption device and analysis method of human exhalation. Background technique [0002] Human exhaled matter contains a large amount of molecular information of human physiological and pathological metabolism. The detection of human exhaled matter provides an important scientific basis for the understanding of human health status and clinical diagnosis. The analysis and detection of human exhalation usually involves the collection and pretreatment of exhalation, such as the use of special exhalation collection bags and collection bottles. These special exhalation collection devices are usually relatively expensive and large in size, and it is difficult to apply them for daily use for a long time. and bulk exhalation collection. Solid-phase microextraction is one of the most commonly used sample pretreatment methods. The so...
