Detection device

Abstract

The invention discloses a detection device which comprises a first cavity used for collection, a second cavity used for detection and a first channel used for connecting the first cavity with the second cavity. An adjusting element is arranged in the first channel and configured to be capable of being used for adjusting connection or sealing between the first cavity and the second cavity. The adjusting element comprises a connecting piece, one end of the connecting piece is connected with a first plunger, and the connecting piece is configured to be used for separating connection between the first channel and the first cavity. The detection device is a complete set of detection device and can collect samples and detect the samples, direct contact with the samples is not needed in the wholedetection process, an excrement solution is sealed in the detection device in the detection process, the whole device is good in sealing performance, a liquid leakage phenomenon is avoided, and a user can conveniently carry out detection by himself/herself.

Description

technical field [0001] The invention specifically relates to a detection device. Background technique [0002] In the field of medical biology, the analysis and detection of samples is the basis of many experiments and treatments. Stool testing is commonly used for early screening of many diseases. Stool is a common solid sample. Fecal occult blood testing can provide early warning of abnormalities in the digestive tract. When the amount of gastrointestinal bleeding is small, the appearance of the stool will not change abnormally and cannot be recognized by the naked eye. Therefore, for patients suspected of chronic gastrointestinal bleeding, fecal occult blood testing should be performed, which is of great significance for early screening of digestive tract malignancies (such as gastric cancer, colorectal cancer, polyps, and adenomas). Colonoscopy is one of the important techniques for diagnosis and population screening. For patients with positive fecal occult blood, colo...

AI Technical Summary

Problems solved by technology

During the detection process, the fecal solution is open, there is no corresponding airtight measures, and the number of times of looking directly at the feces is high. The small cups and small holes are easy to overturn and leak liquid when operating, and gloves are required for operation. The detection equipment is scattered and not easy to carry and transport. Disadvantages make current fecal occult blood self-determination by non-professionals

[0006] At present, operators have safety and hygiene requirements for feces, which are inherently polluting samples, and it is inconvenient to directly contact them

Some feces detection devices include sealing elements, but the sealing of the entire detection device needs to be improved, and the structural design of the detection device is relatively complicated, making the detection operation inflexible

[0007] Most of the feces detection devices on the market cannot control the amount of samples collected, and some detection devices need to be controlled by the testing personnel according to their own experience and work habits; moreover, the existing feces detection devices cannot control the entry into the detection area. Amount of sample solution to be run

However, in the process of detection, the control of the sample volume collected and the sample solution volume often has a great influence on the detection results.

If not well controlled, it will lead to inaccurate test results
