Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0031] Example 1:

[0032] Based on the concept of this application, combined with Figs. 1-2 This document describes an embodiment of a detachable stool sampler for collecting fecal samples. Specifically, the detachable stool sampler is constructed with a split structure, comprising three components: a sampling tube 1, a liquid guiding tube 5, and a collection cylinder 7. Through the coordinated arrangement of the collection cylinder 7, the liquid guiding tube 5, and the connecting tube 3, physiological saline can be added to the fecal sample without contact, diluting and softening the sample to form a sample solution. This reduces the number of steps required by the testing personnel, improves testing efficiency, and also reduces the number of times the sampling tube 1 needs to be opened, preventing the sample odor from dissipating.

[0033] Combination Figs. 1-2 As shown, the present invention provides a detachable stool collector, comprising:

[0034] Sampling tube 1, with a cap 2 inserted at the top of the sampling tube 1, and a connecting tube 3 coaxially installed at the center of the cap 2, and a sampling spoon 4 fixedly connected to the bottom of the connecting tube 3;

[0035] The liquid guide tube 5 is detachably installed at the top of the connecting tube 3. A control valve 6 is installed on the liquid guide tube 5, and a liquid collection cylinder 7 is fixedly connected to the top of the liquid guide tube 5. A cap 8 is detachably installed on the top of the liquid collection cylinder 7.

[0036] Regarding the technical solution of this embodiment, the sampling tube 1 is made of transparent material, and the size of the end cap 2 is adapted to the opening at the top of the sampling tube 1. The sampling tube 1 is convenient for storing fecal samples, and the end cap 2 can seal the sampling tube 1.

[0037] Regarding the technical solution of this embodiment, such as Fig. 1 As shown, the interior of the end cap 2 is a hollow cavity. The bottom of the end cap 2 is fixedly connected to the connecting pipe 3, and a cover plate 9 is fixedly connected to the top of the end cap 2. It should be noted that the top of the connecting pipe 3 is lower than the end cap 2. Therefore, by using the cover plate 9 to snap onto the top of the end cap 2, the end cap 2 can be sealed.

[0038] Regarding the technical solution of this embodiment, the liquid guide tube 5 and the connecting tube 3 are connected by a threaded connection. The top end of the connecting tube 3 is fixedly connected to a threaded post, which is connected to the connecting tube 3. The bottom end of the liquid guide tube 5 is provided with an internal thread that matches the threaded post. The liquid guide tube 5 is installed on the connecting tube 3, and then the control valve 6 is opened to allow the liquid in the collection cylinder 7 to flow down into the sampling tube 1. It should be noted that the inside of the collection cylinder 7 is filled with physiological saline, and the collection cylinder 7 is connected to the liquid guide tube 5. The physiological saline is used to soften and dilute the fecal sample to facilitate the formation of a sample solution for subsequent testing.

[0039] According to the technical scheme of the embodiment, the top end of the liquid collecting cylinder 7 is threadedly connected or clamped with the cover 8, which is not limited in the embodiment, and can be selected according to the actual situation. After the cover 8 is opened, physiological saline in the liquid collecting cylinder 7 can be replenished in time, which is convenient for repeated use, avoids waste caused by one-time use, and also enables the internal pressure of the liquid collecting cylinder 7 to be equal to the external atmospheric pressure after the cover 8 is opened, thereby preventing liquid from flowing down.

[0040] It should be noted that the control valve 6 is a luer two-way valve, which can be controlled to be opened or closed by rotating the handle, thereby controlling the physiological saline to flow down.

[0041] Specifically, when fecal sampling is needed, two cases can be used. In the first case, the liquid collecting cylinder 7 is used together with the sampling tube 1. The user first removes the cover 2 from the sampling tube 1. At this time, the connecting pipe 3 is installed and fixed with the liquid guide pipe 5. The liquid collecting cylinder 7 and the liquid guide pipe 5 can be used as a handle together with the cover 2. Then, the sampling spoon 4 is used to dig part of the sample to complete the sampling. After sampling is completed, the sample is placed in the sampling tube 1, and the cover 2 is sealed to the sampling tube 1. It should be noted that in this case, the user should not twist the control valve 6.

[0042] In the second case, the sampling tube and the cover 2 are used alone. The user first removes the cover 2 from the sampling tube 1. At this time, the liquid guide pipe 5 is separated from the connecting pipe 3. The user covers the cover 2 with the cover plate 9, holds the cover 2, and uses the sampling spoon 4 to dig part of the sample to complete the sampling. After sampling is completed, the sample is placed in the sampling tube 1, and the cover 2 is sealed to the sampling tube 1. Then, the liquid guide pipe 5 is installed on the connecting pipe 3.

[0043] Then, the tester can observe the color of the fecal sample through the sampling tube 1. When further detection is needed, physiological saline is used to soften and dilute. At this time, the tester twists the control valve 6 to open it, so that the physiological saline flows into the sampling tube 1. In this way, the fecal sample can be diluted and softened without contact. Also, opening the cover 2 and adding physiological saline with the help of a dropper is complicated. The connecting pipe 3 and the liquid guide pipe 5 can be installed and separated, which is convenient for cleaning and disinfection after use, repeated use, and avoids waste.
