Description
Technical Field
The utility model relates to a sample sampling structure.
Background
The examination of fecal occult blood means that the amount of bleeding in the digestive tract is very small, the naked eye does not see the blood color, and a small amount of red blood cells are digested and decomposed, so that no bleeding can be found under the microscope. The color of excrement can not be changed due to a small amount of bleeding in the digestive tract of the occult bloody stool, and the color can be determined only by an excrement occult blood test. All digestive tract diseases cause a small amount of bleeding and can be accompanied by occult blood stool, so occult blood examination has important value for diagnosing various digestive tract hemorrhagic diseases, is an effective means for screening digestive tract diseases by general investigation, and occult blood experiments become a hotspot of continuous and deep research of people.
At present, the test paper is commonly used for rapidly detecting the occult blood of the excrement, for example, a Chinese patent with the publication number of CN213843283U discloses an occult blood test paper structure, which comprises a test paper main body, wherein one end of the test paper main body is provided with a handheld area, the inside of a groove is provided with an occult blood test paper, one end of the occult blood test paper is provided with a sample placing area to be detected, one side of the occult blood test paper is provided with a liquid permeability carrying layer, and the other side of the occult blood test paper is provided with an outer surface layer, and the test paper structure is characterized in that: the top of test paper main part is provided with the recess, and the middle part of test paper main part is provided with the folding line.
For another patent application with publication number CN200953022Y, a fecal occult blood test paper is disclosed, which belongs to the field of colloidal gold immunoassay. The test paper is composed of a base plate, a water absorption plate, a nitrocellulose membrane, a single anti-hemoglobin single anti-gold label pad and a glass fiber sample liquid absorption layer, wherein the nitrocellulose membrane is arranged in the middle of the base plate, a transferrin single anti-monoclonal antibody reaction line, a hemoglobin single anti-monoclonal antibody reaction line and a goat anti-mouse polyclonal antibody control line are arranged on the nitrocellulose membrane, the water absorption plate is arranged at one end of the base plate, the glass fiber sample liquid absorption layer is arranged at the other end of the base plate, the two ends of the nitrocellulose membrane are respectively connected with the water absorption plate, the anti-transferrin and the anti-hemoglobin single anti-gold label pad in an overlapped mode, and the glass fiber sample liquid absorption layer is pressed on the gold label pad.
It can be seen from the above two patents that the prior art needs the person to be tested to collect the stool, and the reagent and the stool sample are mixed by using a special sampling tool and a special container, and then the reagent is sucked onto the corresponding test strip or test card to realize the test. When the detected person collects the excrement, the problem of excessive sampling is likely to occur, or various problems are likely to occur due to environmental pollution caused by improper operation.
SUMMERY OF THE UTILITY MODEL

Detailed Description
Example 1
As shown in fig. 1-3, the present embodiment discloses a sampling structure, which includes a sampling head 1 with a cone shape and a sampling groove 2 disposed on the outer side wall of the upper end of the sampling head 1, wherein the sampling groove 2 is disposed on the sampling head 1 in a circular or spiral shape, and after the sampling head 1 is inserted into a sample, a part of stool sample can be retained in the sampling groove 2, so as to achieve the sampling effect.
The top of the sampling head 1 is provided with a conical tip 4.
After the sampling head 1 penetrates into the reagent box after sampling, the sample is mixed with the reagent. The structure of the sampling groove 2 not only can realize the function of convenient sampling, but also can approximately play a role of quantification, thereby being not capable of taking more samples and still meeting the requirement of the sample amount for detection.
This embodiment needs to cooperate the block to use, is equipped with the kit in the block, has the membrane of sealing on this kit, and after block and box body 1 lock, the awl point 4 of sampling head 1 can puncture the membrane of sealing.
In order to make the mixed reagent flow out smoothly, a liquid passing groove 3 is arranged on the side wall of the sampling head 1 and below the sampling groove 2, so that a gap is inevitably left between the sampling head 1 and the sealing film after the sampling head 1 penetrates into the sealing film, the reagent can flow out from the gap, and the mixed reagent is convenient for subsequent detection operation.
When the utility model is used, the sampling head 1 is dipped with a sample and pressed downwards into the cap, the sampling head 1 can puncture the sealing film of the reagent box and enter the reagent box, so that the sample is contacted with the reagent and is flushed into the reagent; then the cover cap is turned upside down, the reagent and the sample in the reagent box can flow out through the liquid flowing groove 3 on the sampling head 1, and the next operation is convenient.
At present, the technical scheme of the utility model is that a pilot test is carried out, namely a small-scale test of products before large-scale mass production; after the pilot test is finished, the investigation for the use of the user is carried out in a small range, and the investigation result shows that the satisfaction degree of the user is higher; the preparation of products for formal production for industrialization (including intellectual property risk early warning research) has been started.
