Description

Excrement collecting device

Technical Field

The invention relates to the field of molecular diagnosis, in particular to a device and a method for collecting a stool sample in stool molecular diagnosis.

Background

Human stool tests are one of the most commonly used test methods in clinical practice at present, and especially have an important role in diagnosing digestive system diseases and parasitic diseases. Human normal feces consist of undigested food residues, such as starch granules, meat fibers, plant cells or plant fibers, digestive secretions or breakdown products, exfoliated epithelial cells from the intestinal wall, intestinal bacteria, and water. The quality of food, the functional status of the stomach, intestine, pancreas, liver, gallbladder or some organic lesions all affect the properties and composition of feces. Therefore, examination of feces can first understand whether there is inflammation, bleeding, and parasitic infection in the digestive tract and associated organs (e.g., liver, gallbladder, pancreas, etc.); secondly, the digestion condition can be known, and the secretion function of organs such as pancreas and the like can be roughly judged; in addition, the early screening of gastrointestinal malignant tumors or digestive system related diseases can be performed by fecal occult blood tests or genetic detection methods. Whether biochemical or molecular testing of feces, subsequent studies are required by collecting human feces. The current excrement collection is not collected by professionals in a unified way, but is collected by individuals and then sent to or mailed to a detection place, the excrement volume required by molecular detection is large, and the deviation of a detection result is caused by unqualified excrement sample collection of individuals. Not only wastes the personal funds and energy of the consumers, but also has the possibility of causing great misjudgment on the following diagnosis and treatment. At present, the common feces collection devices in the market mainly have the following three types: (1) stick types-such as cotton swabs, wooden sticks, wood chips, plastic sheets, etc.; (2) a brush type; (3) a small spoon type. Although the stick type stool sample collection device is low in cost, the operation is uncontrollable, repeated sampling is needed, the sampling amount is easily uncontrollable, particularly, the flowing stool cannot be collected, and the dropping of the stool is easily unsanitary. Although the brush type sampling device reduces the times of reciprocating sampling, the problems of still being incapable of collecting and dripping the liquid excrement and unfixed sampling amount cannot be solved. Although the spoon type partially solves the problem that the liquid feces cannot be collected and dripped, the conventional spoon type still cannot well fix the sample size of the volume. In order to overcome the defects of unfixed sampling amount, unsanitary sampling and the like in the excrement collecting process in the prior art, the invention provides the simple, quick and accurate excrement collecting device, and the device can greatly improve the volume consistency of sample amount sampling.

In addition, the collector-cap integrated device integrates the collector and the cover of the collecting pipe, and a user directly puts a sample into the collecting pipe after collection and screws the cover of the collector-cap integrated device. Meanwhile, the bent handle structure is convenient for users to operate, and through multiple tests, the user experience is better when the included angle between the bent handle structure and the shovel head is 172 degrees.
