Problems solved by technology

[0004] However, the above-mentioned shovel-shaped sampling tank makes it difficult for users to grasp the amount of feces samples collected, which easily affects the final test results; moreover, because the feces are concentrated and piled up in the shovel-shaped sampling tank, it is difficult to quickly dissolve the feces samples into the sampling tank. In the buffer of the device, this situation will also have a certain impact on the test results

Embodiment 1

[0031] like figure 1 As shown, a feces sampling device includes a collector 1 and a sampler 2, buffer solution is contained in the collector 1, and the sampler 2 can be nested in the collector 1, and the collector 1 can It is detachably sealed with the sampler 2, wherein the sampler 2 is provided with a sample pushing device, and the sample pushing device can generate a certain distance of relative displacement in the sampler 2, and the sampler 2 and the The movement of the sealed connection of the collector 1 is synchronized with the movement of the sample pushing device to push the sample out of the sampler 2, and the movement of disassembling and separating the sampler 2 from the collector 1 is synchronized with the movement of the sample pushing device from the sampler 2. The sampling port moves to the inside of the sampler 2 to expose the movement of the sampling cavity synchronously.

[0032] In this embodiment, the sampler 2 is provided with a guiding structure that gu...

Embodiment 2

[0038] like image 3 As shown, a feces sampling device includes a collector 1 and a sampler 2, buffer solution is contained in the collector 1, and the sampler 2 can be nested in the collector 1, and the collector 1 can It is detachably sealed with the sampler 2, wherein the sampler 2 is provided with a sample pushing device, and the sample pushing device can generate a certain distance of relative displacement in the sampler 2, and the sampler 2 and the The movement of the sealed connection of the collector 1 is synchronized with the movement of the sample pushing device to push the sample out of the sampler 2, and the movement of disassembling and separating the sampler 2 from the collector 1 is synchronized with the movement of the sample pushing device from the sampler 2. The sampling port moves to the inside of the sampler 2 to expose the movement of the sampling cavity synchronously.

[0039] In this embodiment, the sampler 2 is provided with a guiding structure that gu...

Embodiment 3

[0047] This embodiment is similar to Embodiment 2, the main difference is that the fixing method of the outer tube 202 is different. The fixing method of the outer tube 202 in this embodiment is that the outer wall of the outer tube 202 is provided with a first protrusion edge, the first flange is provided with a seventh thread, the inner wall of the collector 1 is provided with a second flange, and the second flange is provided with an eighth thread that cooperates with the seventh thread; when the sampler When the 2 sleeves are stacked in the collector 1, the seventh thread and the eighth thread are connected by rotation to realize the rotation of the cover 3 while the outer tube 202 is fixed, so as to ensure that the spiral guide groove 2021 is aligned with the protruding shaft 2031 driving effect. The operation method and principle of this embodiment are the same as those of Embodiment 2.

Abstract

The invention relates to the technical field of medical instruments, specifically to a feces sampling device. The feces sampling device comprises a collector and a sampler, wherein the sampler is placed in the collector in a nestable way, the collector is detachably and hermetically connected with the sampler, a sample pushing device is arranged in the sampler and can carry out relative displacement of a certain distance in the sampler, the sampler is hermetically connected with the collector while the sample pushing device is pushing a sample out from the interior of the sampler, and the sampler is detachably disconnected with the collector while the sample pushing device is moving from a sampling mouth to the interior of the sampler to expose a sampling chamber. The feces sampling device is simple in structure and convenient to use, facilitates a user in effective controlling of a sampling amount during feces sampling and enables the feces sample to be conveniently and rapidly dissolved into a buffer, thereby obtaining more accurate examination results.

Description

technical field [0001] The present invention relates to the technical field of medical appliances, and more specifically, to a stool sampling device. Background technique [0002] At present, the common stool test usually uses a collector to collect a small part of the sample from the patient's stool for detection. Certain organic molecules in feces (such as DNA components and hemoglobin) can be used as markers for certain gastrointestinal diseases. Quantitative detection of organic molecules in human feces can help us understand some pathological phenomena in the gastrointestinal tract and indirectly judge gastrointestinal diseases. It can predict and monitor the occurrence and development of some gastrointestinal diseases. Therefore, stool testing has become a routine item for many medical units to detect diseases. [0003] In the existing stool detection process, the patient usually collects the stool into a stool sampling device. The stool sampling device generally sto...
