Sequential fecal occult blood collecting and detecting integrated device

Abstract

The invention relates to the technical field of medical detection articles and in particular to a sequential fecal occult blood collecting and detecting integrated device. The sequential fecal occultblood collecting and detecting integrated device adopts a double-sleeve design, three built-in test tubes are used for preloading detection liquid, a fecal sampler is used for collecting a fecal sample, bottom sealing membranes of the three built-in test tubes are punctured by needling, so testing medicaments in the built-in test tubes are mixed with the fecal sample; because the bottom of a jacket test tube is completely separated to form two separated spaces by a separating plate, mixed liquid at the left side can be used for detecting occult blood of an upper gastrointestinal tract, and mixed liquid at the right side can be used for detecting the occult blood of a lower gastrointestinal tract. The sequential fecal occult blood collecting and detecting integrated device is capable of integrating the sampling and the detection, simultaneously detecting upper gastrointestinal hemorrhage diseases and lower gastrointestinal hemorrhage diseases, greatly improving the detection efficiency,reducing the detection difficulty, enabling a non-specialized person to perform the detection easily, adopting a sealed-type design, wherein medical wastes after the detection cannot be leaked out, and avoiding the environmental pollution and pathophoresis.

Description

technical field [0001] The invention relates to the technical field of medical detection supplies, in particular to an integrated device for sequential fecal occult blood collection and detection. Background technique [0002] Since Vandeen invented the GUALAC method to detect fecal occult blood in 1864, it has provided a non-invasive, simple and rapid detection method for the diagnosis of clinical gastrointestinal bleeding and gastrointestinal tumors. Over the past 100 years, this method has made great progress. At present, occult blood examination methods can be divided into five categories:   radiation analysis, physical method, chemical method, immune method and heme-porphyrin test. [0003] The chemical method is represented by the guaiac test. The principle is that the metheme part of the hemoglobin molecule has pseudoperoxidase (pseudoper-oxidase) activity, which can catalyze the cracking of hydrogen peroxide, and its derivatives are coupled with the indicator. , Ox...

AI Technical Summary

Problems solved by technology

However, the sequential fecal occult blood test will be limited by the detection fluid when performing the detection of upper gastrointestinal occult blood and lower gastrointestinal occult blood, and cannot be carried out at the same time. Under the existing medical technology, different samples are tested separately in the laboratory, so that It is concluded that when detecting occult blood in the upper gastrointestinal tract, the stool sample is first placed in a test tube, dripped with piramidone solution, left to stand for a few minutes, then dripped with a mixture
