Excrement collecting, storing and detecting device and method

Abstract

The invention discloses an excrement collecting, storing and detecting device and method. The device comprises a collector and a sample storage flow divider, wherein the collector comprises an upper sleeve, a lower sleeve, a support rod, a spring, a push rod and an umbrella surface; the umbrella surface uniformly covers the support rod and realizes the opening and the contraction through the support rod; the upper sleeve and the lower sleeve are detachably connected; the upper sleeve is provided with a first hollow inner cavity; the upper end of the lower sleeve is provided with an opening andis provided with a second hollow inner cavity; the spring and the support rod are positioned in the second hollow inner cavity; the lower end of the support rod passes through the spring and then extends out from the lower end of the lower sleeve; the push rod penetrates through the first hollow inner cavity of the upper sleeve from top to bottom, then extends into the second hollow inner cavityof the lower sleeve and is abutted against the upper end of the support rod; and the sample storage flow divider comprises a storage liquid cavity, a piston cavity and a flow division cavity in sequential connection. The excrement collecting, storing and detecting device and method have the characteristics that the cost is low; the manufacturing is simple; the surface sample can be effectively scraped; the semi-quantification can be realized; and the operation is simple; the learning is easy, and the like. The uncomfortable experience of experimenters is greatly avoided.

Description

technical field [0001] The invention belongs to the field of clinical sample collection and nucleic acid detection, and in particular relates to a device for collecting, storing and quantitatively transferring stool samples for nucleic acid detection and a corresponding detection operation method. Background technique [0002] Stool is an important clinical specimen type, and biochemical and molecular biological analysis of stool has important reference value for judging digestive system diseases. Colorectal cancer (CRC) is a common malignant tumor, including colon cancer and rectal cancer. one. Only 5% of colorectal cancers are diagnosed at an early stage, and most patients are already in stage II or advanced stage when they are discovered. Scholars at home and abroad suggest that colorectal cancer screening should be carried out regularly, so as to improve the early diagnosis rate and reduce the incidence rate. The results of most foreign studies have shown that colorec...
