Problems solved by technology

The stool sampler of the prior art mainly has the following disadvantages: 1. Sampling by a spoon, the sampling area is small, the sampling size is random, and multiple points cannot be sampled; Pollution; 3. The amount of diluent used is large, the extraction is not clean, and there are many residual liquids to be tested, which may easily lead to environmental pollution and secondary pollution; 4. During the process of adding diluent, the diluent injection needle is easily dissolved Fluid contamination after sample, resulting in diluent needle carryover

Embodiment 1

[0029] Such as Figure 1 to Figure 5 As shown, a kind of stool bioseparation sampler of the present invention comprises cup body 1, and described cup body 1 is connected with cup cover 2, and described cup cover 2 is connected with strip sampler 3, and described strip sampler 3 Several sampling barbs 31 are provided, and the inner cavity of the cup body 1 is provided with a filter partition 4, and the filter partition 4 divides the inner cavity into a dilution chamber 11 and a sampling chamber 12, and the inside of the filter partition 4 is set There is a filter screen 41, and the dilution chamber 11 and the sampling chamber 12 are connected to each other through the filter screen 41; the strip sampler 3 is arranged inside the dilution chamber 11; the cup cover 2 is provided with a dilution injection hole 21 And sampling hole 22, described dilution injection hole 21 is positioned at the top of dilution cavity 11, and described sampling hole 22 is positioned at the top of sampl...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 is that the first isolation layer is a waterproof and breathable film, and the waterproof and breathable film can also play a breathable role, so that it can be discharged from the sampling chamber 12 during the process of adding diluent. The air in the upper part makes the diluent filling process go smoothly. On the other hand, the waterproof and air-permeable film is convenient for the puncture of the sampling needle, and absorbs the liquid to be tested.

[0042] The rest of this embodiment is the same as Embodiment 1, and will not be repeated here.

Embodiment 3

[0044] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 lies in that: the strip sampler 3 is provided with a sampling through hole 32 , and the sampling through hole 32 and the sampling barb 31 are staggered from each other. The belt sampler 3 of this embodiment is provided with a sampling through hole 32, so that the belt sampler 3 is suitable for sampling thinner feces, which cannot be bonded to the barbs 31 due to poor viscosity. The setting of the sampling through hole 32 can well make up for this situation, because the thinner feces are liquid, and the liquid feces can be adsorbed in the inside of the sampling through hole 32, so the strip sampler 3 with the sampling through hole 32 can be completed. Sampling of thinner stools.

[0045] In addition, the sampling through hole 32 can have the above-mentioned functions, and it is also convenient for the diluent to wash out the feces sample of the strip sampler 3. The through hole 32 can s...

Abstract

The invention relates to the technical field of a medical machine, and particularly relates to an excrement bio-separation sampler. The excrement bio-separation sampler comprises a cup body, wherein the cup body is connected with a cup cover; the cup cover is connected with a strip-shaped sampler; sampling barbs are arranged on the strip-shaped sampler, so that a sampling area of the strip-shaped sampler is large; if the sampling barbs can be in multi-point contact with an excrement sample, the multi-point sampling of the excrement sample is realized, so as to ensure that ingredients in a detection project are prevented from being leaked to sample, and the sampling amount is constant; in the dilution liquid adding process, a dilution liquid sampling needle needs to penetrate a sealing rubber plug at a dilution injection hole; the sealing rubber plug is matched with the dilution liquid sampling needle in a sealed manner, so that liquid and gas are prevented from leaking before the process of penetrating through the dilution liquid sampling needle; in the process of penetrating the dilution liquid sampling needle and after the process of penetrating through the dilution liquid sampling needle through the sealing rubber plug, the environment pollution is avoided; and the sealing rubber plug has a certain fixing effect on the dilution liquid sampling needle, so that the liquid after a sample is dissolved can not be contacted in the dilution liquid sampling needle, and the dilution liquid sampling needle is prevented from carrying the pollution.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bioseparation sampler for feces. Background technique [0002] The feces sampler of prior art generally has two types, and a kind of is used for manual operation, mainly is made up of cup body and cover; It is composed of a sampling spoon and a strainer. The stool sampler of the prior art mainly has the following disadvantages: 1. Sampling by a spoon, the sampling area is small, the sampling size is random, and multiple points cannot be sampled; Pollution; 3. The amount of diluent used is large, the extraction is not clean, and there are many residual liquids to be tested, which may easily lead to environmental pollution and secondary pollution; 4. During the process of adding diluent, the diluent injection needle is easily dissolved Fluid contamination after the sample, resulting in carryover contamination of the diluent needle. Contents of the invention [0003] ...
