Disposable intestinal tumor screening detection cannula

Abstract

The invention provides a disposable intestinal tumor screening detection cannula. The technical problem that the environment is polluted and the effectiveness of samples is also affected during existing gastrointestinal tumor excrement screening, acquisition and detection and large-scale popularization and application are difficult to perform is solved. The disposable intestinal tumor screening detection cannula is provided with a housing and an excrement sampling core, wherein the excrement sampling core comprises an outer cannula, a puncture needle is arranged in the middle of the outer cannula, an outer cannula connecting end is arranged at the upper end face of the outer cannula, the front end of the housing is connected with the housing connecting end, a reaction agent cavity is formed in the lower end of the inner cavity of the housing and is provided with a color developing agent cavity in parallel with reaction agent cavity, an isolating membrane is arranged between the reaction agent cavity and the color developing agent cavity, and a sealing film is arranged at the upper end of the color developing agent cavity. The disposable intestinal tumor screening detection cannula can be widely applied to excrement acquisition and detection and rapid and accurate judgment of detection results in common domestic gastrointestinal tumor screening.

Description

technical field [0001] The invention relates to a detection device, in particular to a disposable intestinal tumor screening detection sleeve. Background technique [0002] As we know, the existing method of collecting and detecting feces for gastrointestinal cancer screening is to use manual operation of cotton swabs or small plastic sticks to pick up and collect some feces, then put the feces into small plastic cups or test tubes, and then pour them into small plastic cups or test tubes. Add detection reagents in the test, mix the feces with the reagents, and then judge the results, and then fill in the information form, summarize and report the information in turn. The detection method is cumbersome, time-consuming and labor-intensive. During the sample preparation process, the reagents and samples are always in an open communication state with the ambient air, which is easy to pollute the environment and affect the validity of the sample. Moreover, this detection can onl...

Problems solved by technology

[0003] The present invention aims at the cumbersome process of collecting and detecting feces screening for digestive tract tumors, which is time-consuming and labor-intensive. During the sample preparation process, the reagents and samples are always in an open and intercommunicating state with the ambient air, which is easy to pollute the environment and affect the effectiveness of the samples. In addition, this kind of detection can only be carried out in professional medical institutions, and it is difficult to carry out large-scale promotion and application of technical problems. It provides a simple process, saves time and effort, and during the sample preparation process, reagents and samples will not be mixed with each other. The ambient air is in an open and interoperable state, which neither pollutes the environment nor affects the validity of the sample. It can be carried out not only in professional medical institutions, but also for a large-scale popularization and application of digestive tract tumor stool screening collection and testing kit
