Description

A fully sealed secondary quantitative selective sampling stool specimen box

technical field

The utility model belongs to the technical field of medical and sanitation clinical examination, and in particular relates to a fully sealed disposable feces sample which can be sampled twice quantitatively and has a selective sampling function, and which is used for an automatic stool test operation instrument box.

Background technique

Among the three routine tests done on patients in the hospital, the stool routine test is one of the items that must be checked. In addition to the necessary routine stool testing of the patient, according to the patient's condition, some necessary gold standard or chemical testing and observation under the microscope should be carried out on the patient's stool sample to make an accurate diagnosis of the patient.

At present, there are two methods of routine stool inspection: manual inspection and semi-automated instrument inspection. The problem with manual detection is that during the operation, the stool sample is exposed to the air, which has a great impact on the entire test operation environment, and the operator is easily infected by the sample. The function of the specimen box used in semi-automatic instrument detection is simple and single. Most of the specimen boxes have a left and right multi-chamber structure, and the function is only to collect and stir the specimen once. The disadvantages are: it cannot be used for different specimen volumes and different specimens. Quantitative detection; after the sample is diluted, there are fewer detection substances under the microscope, and it is impossible to make a correct and accurate judgment on the patient's condition; the left and right multi-chamber specimen boxes make the patient misplaced when sampling or correctly placed. inside the sampling chamber.

201320805443.9 discloses a specimen box for stool testing. The sample of this utility model cannot be stirred and cannot be used for secondary detection. 201120343631.5 relates to a disposable machine-used stool specimen box, including a barrel-shaped box body and a box cover threadedly connected to the opening end of the box body; axial positioning ribs are provided on the outside of the box body; The rotating rod of the lid, the rod surface of the rotating rod stretching out from the top of the lid is provided with threads opposite to the thread direction on the lid. The sample collected by the utility model cannot be stirred, cannot be used for secondary collection, and cannot be selectively sampled.

Utility model content

The technical problem to be solved by the utility model is to provide a feces specimen box which has good sealing effect, can collect specimens quantitatively twice, and has selective sampling.

The technical scheme of the utility model is achieved in that:

A fully sealed secondary quantitative and selective sampling stool specimen box, comprising a specimen box body and a specimen box cover, a partition is provided in the specimen box body, a sampling port, an extrusion device, and a stirring device are provided on the sample box cover and a filter screen device, the sampling port is provided with a sealing sticker, and the filter screen device is fixed in the stirring device, and it is characterized in that: the two sides of the partition are inclined chamfers, and the bottom of the partition is provided with a seal membrane, and the sealing membrane divides the specimen box body into a primary sampling cavity and a pre-treatment cavity for secondary sampling.

In the stool specimen box of the present utility model, the extruding device is fixedly mounted on the specimen box cover, and the stirring device is a retractable structure, and is rotatably arranged on the specimen box cover superior.

In the stool specimen box of the present utility model, a sampling cavity is provided in the stirring device, and the sampling port is located above the sampling cavity.

In the stool specimen box of the present utility model, the filter screen device is composed of an inner net and an outer net.

In the stool specimen box of the present utility model, the aperture of the outer net is larger than the aperture of the inner net.

The feces specimen box implementing the utility model has the following beneficial effects: the utility model can stir the specimen, and at the same time, the specimen can be subjected to secondary quantitative sampling, and redundant specimens can be separated to avoid entering the pre-treatment chamber of the secondary sampling. , to facilitate the preservation of relatively pure specimens that can be used for secondary testing. When the sample quantitatively squeezed into the pre-treatment chamber of the secondary sampling is diluted and stirred, the selectively collected substances can pass through the large-diameter filter in the filter device and enter the sampling chamber, and then be collected by the small filter on the other side. The aperture filter is blocked and retained in the sampling chamber. After a certain period of stirring and mixing, the concentration of the substance selectively collected in the sampling chamber is much higher than that outside the sampling chamber, which plays the role of selective sampling. The high-concentration sample liquid collected in the sampling chamber is subjected to microscope detection and various gold standard detection. The specimen box is a fully sealed structure, which can support the transmission of the hospital pneumatic logistics system. Squeezing quantitative specimens, diluting, stirring and mixing, and taking sample liquids are all carried out in a sealed state, which avoids the air pollution caused by the peculiar smell of the specimens and protects the equipment and inspectors.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

The full-sealed secondary quantitative selective sampling stool specimen box as shown in Figures 1 to 4 includes a specimen box body 1 and a specimen box cover 2, and a partition 3 is arranged in the specimen box body 1, and the partition board 3 Both sides are inclined and chamfered, and the bottom of the partition 3 is provided with a sealing film, and the sealing film divides the specimen box body 1 into a primary sampling chamber 7 and a pre-processing chamber 8 for secondary sampling.

The sample box cover 2 is provided with a sampling port 10, an extruding device 6, a stirring device 4 and a filter screen device 5, the extruding device 6 is fixed on the sample box cover 2, and the stirring device 4 is A retractable structure, which is rotatably arranged on the specimen box cover 2 . The stirring device 4 is provided with a sampling chamber 9 , and the sampling port 10 is located directly above the sampling chamber 9 . The sampling port 10 is provided with a sealing sticker, and the filter screen device 5 is fixed in the stirring device 4. The filter screen device 5 is composed of an inner net and an outer net, and the aperture of the outer net is larger than the The aperture of the inner mesh.

When the utility model is in use, the specific operation process is as follows: the sampler opens the sample box cover 2, uses a matching disposable sampling spoon, picks an appropriate amount of feces samples into the first sampling cavity 7, and covers the sample box cover 2, Send to the inspection site (can be sent through the hospital pneumatic logistics system). After the inspector receives the specimen box, he can affix a barcode label on the place where the barcode is pasted and put it into the automatic inspection instrument in turn. The inspection instrument pierces the sealing sticker pasted on the specimen box cover 2 through the sampling needle, squeezes the stirring device 4, the filter device 5 and the quantitative sample into the pre-treatment chamber 8 for secondary sampling, and injects the diluent into the sampling chamber 9 , the diluent leaks through the filter device 5 into the pre-treatment chamber 8 for secondary sampling.
