Abstract

The invention relates to the technical field of medical instruments, and provides a sample collection device, comprising a casing and an absorbing member for absorbing gas, wherein the casing is provided with a gas inlet, a gas outlet, a first passage, a second passage, and a detection chamber; the absorbing member is disposed in the detection chamber, and the detection chamber is provided with adetection window that is covered with a shielding layer; the first channel is communicated with the gas inlet, the second channel is communicated with the gas outlet, one side of the detection chamberis provided with a first channel communicating the first passage and the detection cavity, and the other side of the detection chamber is provided with a second channel communicating the second passage and the detection cavity. Through the guiding action of the first passage and the first channel, the gas exhaled by the test subject is introduced into the detection chamber from one side of the detection chamber, and then discharged from the other side of the detection chamber through the second passage and the second channel, which helps the gas to fully contact the absorption member in the detection chamber, thereby improving sample collection efficiency.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a sample collection device. Background technique [0002] In the medical field, the method of breath test is used to diagnose certain diseases, which is fast, safe and painless, and is helpful for early diagnosis and treatment of diseases. For example, for the detection of Helicobacter pylori, the subject is given oral isotope-labeled carbon ( 13 C. 14 C) The urea drug, which contains isotope-labeled CO produced after the drug enters the human body and decomposes 2 Exhale as the subject breathes out, collect exhaled gas samples, and detect the isotope-labeled CO 2 Correspondingly, whether the subject is infected with Helicobacter pylori and the degree of infection can be obtained. In the prior art, when collecting the exhaled gas of the subject, the sample carrier is simply placed on the carrying tool, and then exhaled against the sample carrier so that the sample...
