Description

A specimen box used for pretreatment of feces detection

technical field

The utility model relates to a specimen box used for pretreatment of feces detection, which belongs to the technical field of medical instruments.

Background technique

Stool analysis is one of the routine clinical laboratory tests. Through this examination, some pathological phenomena of the gastrointestinal tract can be intuitively understood, and the functional status of the digestive tract, pancreas, and liver and gallbladder can be judged indirectly. Divided into general character observation with the naked eye, microscopic examination and chemical examination. The collection of stool samples is the first step in stool analysis. At present, the usual operation steps are as follows: the nurse hands over the specimen box to the patient, and the patient collects the specimens in the specimen box and then sends them to the laboratory. After homogenization, filtration and other operations, smear microscopy operation is carried out, and the tested specimens need to be disinfected and other treatments. During this process, the specimens and the odor they produce are likely to pollute the external environment.

In order to reduce the labor intensity of inspectors and reduce the pollution to the external environment, there are also special specimen box products for feces detection on the market. Due to the need to realize the main functions of specimen sampling, automatic mixing of specimen diluent, diluent filtration, and specimen box sealing, etc., Common products have complex structural design and processing, which can only meet part of the above functions or fail to achieve the design function goals.

The utility model comprises a specimen box body and a specimen box cover. The middle part of the specimen box body is rectangular, and the two sides are semicircular. And the filter sampling part, the stirring part is perpendicular to the joints on both sides of the filter screen, and the formed cavity will generate a certain resistance near the inner wall when mixing and stirring, which will offset the centrifugal force generated by the rotation of the stirring shaft so that the center liquid level is low. The phenomenon of high liquid level on the inner wall improves the mixing efficiency. The bottom of the sample box of the stirring part is a slope, which is used to speed up the speed of cells and eggs waiting for the detection content to enter the filter screen during stirring and mixing. There is a hemispherical groove in the center of the bottom of the sample box for filtering and sampling, which is used to collect the eggs that have been filtered and settled at the bottom of the cup. The sampling needle absorbs the filtered sample solution here to improve the detection accuracy.

The sample box cover is closely connected with the sample box body, and the sample box cover is provided with a stirring sampler and a sampling port, the stirring sampler corresponds to the stirring part of the sample box body, and the sampling port corresponds to the filter sampling part of the sample box body.

One end of the stirring sampler is a hemispherical groove for collecting stool samples, the other end of the stirring sampler is a cylindrical connector, and there is a gear surface near the connector, and the cylindrical connector and the rotating part After the interface is connected, the rotating part can be connected with the agitating sampler and stuck in the specimen box cover. The rotation of the rotating part can drive the agitating sampler to rotate. There is a cross-shaped groove in the center of the rotating part, and the retaining surface can prevent the sample liquid from Spills and odor leaks.

The sampling port is sealed with a silica gel valve, and the silica gel valve is circular with a cross opening in the middle to prevent overflow of sample residual liquid and leakage of peculiar smell.

The utility model has the following beneficial effects: the inside of the specimen box is divided into a stirring part and a filtering sampling part, the middle part is separated by a filter net, the middle part of the specimen box body is rectangular, and the two sides are semicircular, and the stirring part and the filter net both sides are connected Vertical, the formed cavity will generate a certain resistance near the inner wall when mixing and stirring, which will offset the centrifugal force generated by the rotation of the stirring shaft, making the center liquid level low and the inner wall liquid level high, which improves the mixing efficiency. The bottom of the sample box is a slope, which can speed up the speed of cells and eggs waiting for the detection content to enter the filter when stirring; the bottom center of the sample box is equipped with a hemispherical groove for centralized filtration. For the insect eggs deposited at the bottom of the cup, the sampling needle absorbs the filtered sample solution here to improve the detection accuracy; there is a shelf at the connection between the stirring sampler and the rotary sampling to prevent the sample solution from overflowing and odor leakage; the sampling port is set It is sealed with a silicone valve, the silicone valve is circular, and there is a cross opening in the middle to prevent the residual sample liquid from overflowing and the leakage of peculiar smell.

detailed description

Now in conjunction with the accompanying drawings in the utility model embodiment, the utility model is further described in detail.

In Fig. 1 and Fig. 4, a specimen box used for pretreatment of feces detection includes a specimen box body 1 and a specimen box cover 2, the middle part of the specimen box body 1 is rectangular, and the sides are semicircular, and the specimen The box body 1 is provided with a filter screen 3, and the filter screen 3 separates the sample box body into a stirring part 4 and a filter sampling part 5, the bottom of the sample box body of the stirring part is an inclined plane, and the sample box body of the filter sampling part There is a hemispherical groove in the center of the bottom.

In Fig. 1 and Fig. 2, the specimen box cover 2 is closely connected with the specimen box body 1, and the specimen box cover 2 is provided with a stirring sampler 6 and a sampling port 8, and the stirring sampler 6 corresponds to the specimen case body 1 The stirring part 4 and the sampling port 8 correspond to the filter sampling part 5 of the specimen box body 1 .
