Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "bottom" and "top "Face", "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.

[0021] Such as Figure 1-Figure 3 As shown, a kind of feces sampling device that can be stored includes a tube body 10, and a negative pressure chamber 11, a negative pressure channel 12, a storage cavity 13 and a suction channel 14 communicated in sequence are opened in the tube body 10, and the suction channel 14 The channel opening 141 communicates with the outside world, and the negative pressure chamber 11 is used to press to generate negative pr...

Abstract

The invention discloses a storable excrement sampling device. The storable excrement sampling device comprises a tube body, wherein a negative pressure cavity, a negative pressure channel, a storage cavity and a suction channel which are communicated in sequence are formed in the tube body; a channel opening of the suction channel is communicated with the outside; the negative pressure cavity is used for generating negative pressure by pressing, so that excrement is sucked from the channel opening and stored in the storage cavity; the cross section of the storage cavity is greater than that of the suction channel; a blocking ring is arranged at the communication part of the storage cavity and the negative pressure channel; the center of the blocking ring protrudes towards one side of the suction channel; a negative pressure hole is formed in the central protrusion of the blocking ring. In conclusion, the storable excrement sampling device has the beneficial effects that when the excrement needs to be sampled, air in the negative pressure cavity is exhausted by pressing the negative pressure cavity, then the tube body is inserted into the anus of a patient by 0.5 to 2 cm, the excrement is sucked from the channel opening by slowly loosening the negative pressure cavity, the excrement is blocked in the storage cavity due to the blocking of the blocking ring, and finally the tube body is taken out to complete sampling of the excrement.

Description

technical field [0001] The present invention relates to fecal sampling devices and, more particularly, to a storable fecal sampling device. Background technique [0002] Stool examination is one of the routine clinical laboratory examination items. Through this examination, some pathological phenomena of the gastrointestinal tract can be more intuitively understood. In stool examination, most of the samples are semi-solid, and a sampling device is required to take samples before sending them for inspection. Hospitals now usually allow patients to take samples by themselves with test tubes and cotton swabs, but feces are easily polluted by the external environment during the sampling process, which affects the test results. [0003] Combining the above reasons, how to avoid contamination of feces during the sampling process from affecting the test results is the problem considered in this application. [0004] For this reason, many manufacturers and people of insight carry o...
