Explanation of symbols: 1-air bag, 2-electronic nose detection device, 3-gas delivery hose, 4-suction nozzle, 5-movable valve, 6-clip, 7-gas tank, 8-gas detection sensor array, 9- Wire, 10-data processing device, 11-interface tube.

Detailed ways:

A gas collection and detection device, characterized in that it includes an air bag 1 for collecting and storing gas, an electronic nose detection device 2 for detecting gas, and a gas delivery hose 3 for connecting the air bag and the electronic nose detection device;

The air bag is sealed and packaged, which is convenient for use and storage. The gas in the air bag is transported to the electronic nose detection device through the gas delivery hose. The electronic nose detection device detects the gas and generates an odor map.

In one embodiment, one end of the air delivery hose is sealed and connected to the air bag, and the other end is provided with a suction nozzle 4, which can be sealed and detachably connected to the electronic nose detection device, and the outer circumference of the air delivery hose is The wall is also provided with an active valve 5 for adjusting the gas delivery rate and a gas hose clamp 6 for closing the gas hose;

The movable valve is used to adjust the gas delivery speed of the gas delivery pipe, and the clip is used to clamp the hose to completely close the hose to prevent air leakage. The detachable socket with the electronic nose can facilitate replacement after each measurement.

Further, the electronic nose detection device includes a sealed gas tank 7, a gas detection sensor array 8 arranged inside the gas tank for detecting gas, and a data processing device electrically connected to the gas detection sensor array through a wire 9 arranged outside the gas tank Device 10, the air tank is provided with an interface tube 11 connected to the inside, which can be sealed and detachably connected with the suction nozzle;

The gas detection sensor array is composed of multiple gas sensors, which can detect various data indicators (flow rate, concentration, etc.) of the gas as needed and transmit the data to the data processing device. Atlas, the data processing device may have its own screen capable of displaying atlases or use an external display to display atlases.

An embodiment, the air bag is a disposable drainage bag with a volume of 1000 milliliters;

Disposable drainage bag is a common material in the medical field. It is convenient and quick to use, low in cost, has good sealing performance, is convenient for gas collection and storage, and has a fixed volume, which can improve the accuracy of gas detection results.

A method for using the above-mentioned gas collection and detection device, which includes the following steps:

a. The mouth of the sample to be tested contains the suction nozzle and blows until the air bag is full;

b. Adjust the movable valve to the minimum rate and clamp the air hose with the air hose clamp to completely close the air hose;

c. After adjusting the parameters of the electronic nose detection device, seal the suction nozzle with the electronic nose detection device;

d. Set the running time of the electronic nose detection to 120 seconds. In the running state, the gas to be tested will not be detected for the first 10 seconds. At the 10th second, remove the clip of the gas delivery hose and adjust the valve to allow the gas to enter the gas tank to start detection. gas;

e. The gas detection sensor array detects the gas and transmits the value to the data processing device until the gas delivery is completed. The data processing device records the value and generates an odor map at the same time.

Further, before testing the sample to be tested, the gas exhaled by the unaffected sample is detected according to the above steps, and the initial parameters of the electronic nose detection device are adjusted with the obtained value;

After the initial parameter adjustment of the electronic nose detection device is completed, the exhaled gas of the diseased sample is detected first, and the corresponding disease characteristic odor spectrum is generated, and then the exhaled gas detection is performed on the sample to be tested, and the odor spectrum of the sample is generated and compared with the previous The obtained disease characteristic odor spectra are compared, and finally it is determined whether the test sample is diseased or not.

The purpose of this utility model is to provide a gas collection and detection device, which can quickly and accurately collect, store and detect the gas exhaled by the patient, thereby helping to diagnose the patient's illness. The collection device is standardized, the gas is convenient to store, and the detection result is accurate and reliable. Easy to use on a large scale.
