Abstract

The invention relates to a bag for sampling gas used for a breath test, which comprises a sampling bag body and a blowing nozzle arranged on the sampling bag body, a gas inlet channel and a gas outlet channel are provided in the blowing nozzle which are communicated with the sampling bag body, a gas cover used for opening and sealing the gas inlet channel is provided at a gas inlet of the gas inlet channel, a gas plug used for opening and sealing the gas outlet channel is provided at a gas outlet of the gas outlet channel. According to the invention, the design of the gas inlet channel and the gas outlet channel is used for discharging the gas inhaled from the gas inlet channel through a first in first out mode from the gas outlet channel, so that accurate collection of the exhalant pulmonary gas near the end of the breath of testee can be ensured, and the precision and accuracy of the breath tests are enhanced.

Description

technical field [0001] The present invention relates to medical supplies, more specifically, to a gas sampling bag for breath test. Background technique [0002] Breath test is a non-invasive method to detect Helicobacter pylori (Hp). The breath test requires the subject to first take a drug containing C13 markers, and then collect the exhaled gas through a sampling bag for testing. [0003] At present, the sampling bag used for sampling sample gas is usually provided with an air blowing nozzle as an air inlet on the sampling bag body, and the subject directly blows the gas into the sampling bag body through the air blowing nozzle. Cover the air cap to seal the blowing nozzle. However, during the breath test gas sampling process, the initial part of the gas exhaled by the subject is the gas in the mouth and throat, followed by the gas in the lungs that the breath test needs to collect. However, ordinary sampling bags often can only collect the initial part of the gas and ...
