Description

Technical Field

[0001] The utility model relates to the technical field of medical and health clinical testing, in particular to a sputum sample cup. Background Art

[0002] This technology is specially invented to improve operational efficiency, reduce manual contact and enhance biosafety in medical, laboratory or other experiments that require pre-processing of biological samples.

[0003] my country's public patent "A closed stirring retention device (CN215140016U)", the utility model relates to a closed stirring retention device, including a cup body, a cup cover covering the cup body, and a sampling device arranged in the cup body; the sampling device includes a central axis, a sleeve and a coating head; a quantitative cavity is provided at the top of the coating head, and a needle nozzle connected to the quantitative cavity is provided at the bottom; the bottom of the sleeve extends into the quantitative cavity from the top of the coating head, and the sleeve is slidably matched with the inner wall of the quantitative cavity on all sides; the sleeve is connected to the coating head through an elastic member in a compressed state; the sleeve is fixed to the bottom of the central axis; the central axis is connected to the cup cover, and the top extends from the top of the cup cover; when the cup cover is closed, the elastic member is in a compressed state, and when the cup cover is unscrewed, the elastic member bounces up, the volume of the quantitative cavity increases, and the specimen is sucked into the quantitative cavity. When smearing, the elastic member is compressed again, so that the specimen can be squeezed out of the fixed volume cavity and smeared on the glass slide to complete the smearing; the whole process does not require manual contact with the specimen, and sampling is performed in a closed container, which improves biological safety.

[0004] During the use of the above-mentioned device, it was found that although the bottle cap does not need to be opened during the stirring process, the bottle cap still needs to be opened when sampling and pouring the sample. The pouring and sampling processes still involve direct manual contact with the specimen, which may not only cause specimen contamination, but also increase the biosafety risk of the operator. In addition, the inspection technology often involves the step of diluting the sample. When diluting the sample, the above-mentioned device cannot directly add diluent to the bottle to dilute the sample. The bottle cap also needs to be opened. When adding the diluent, the diluent is easy to splash out to the outside, causing pollution to the environment, and there is also a safety hazard to the staff. Utility Model Content

[0026] See also Figure 1-6 A sputum sample cup of the utility model comprises a cup body 1, a first cup cover 6, a second cup cover and a stirring rod 14. A first connecting piece 5 is integrally formed on the top of the cup body 1, the first cup cover 6 is movably connected to the first connecting piece 5, a second connecting piece 10 is arranged at the center of the inner wall of the first cup cover 6, the second cup cover is movably connected to the second connecting piece 10, a plurality of crushing blocks 3 are arranged on the inner wall of the cup body 1 and near the bottom, a cutting paddle 17 is fixedly connected to the outside of the stirring rod 14, a diversion channel 15 is opened in the center of the stirring rod 14, a first through hole 16 is opened in the center of the bottom of the stirring rod 14, a connector 4 is fixedly connected to the top of the stirring rod 14, a second through hole 18 is opened in the center of the top of the connector 4, the second through hole 18, the diversion channel 15 and the through hole are connected to each other, and the stirring rod 14 passes through the middle part of the first cup cover 6 and is inserted into the inside of the cup body 1.

[0027] In this embodiment, in order to improve the mixing efficiency of sputum and diluent, a funnel-shaped recessed portion 2 is integrally formed at the bottom of the inner wall of the cup body 1, and there are four crushing blocks 3. The four crushing blocks 3 are distributed on the surface of the recessed portion 2 in a circular shape with the center of the cup body 1 as the origin and at equal distances.

[0028] When the stirring rod 14 rotates, the cutting paddle 17 cooperates with the breaking block 3 to quickly break up the sputum. Compared with the pure stirring method in the prior art, the mixing efficiency of the sputum and the diluent can be greatly improved.

[0029] In this embodiment, in order to facilitate the connection between the first cup cover 6 and the cup body 1, the first connecting piece 5 is annular, the inner diameter of the first connecting piece 5 is the same as the maximum inner diameter of the cup body 1, the outer diameter of the first connecting piece 5 is smaller than the outer diameter of the cup body 1, and the first cup cover 6 and the first connecting piece 5 are threadedly connected.

[0030] The above technical solution makes it convenient for the staff to open and seal the first cup cover 6.

[0031] In this embodiment, in order to facilitate the connection between the first cup cover 6 and the second cup cover, a groove 8 is opened in the center of the top of the first cup cover 6, and a limiting step 9 is opened in the middle of the groove 8. The second cup cover includes a limiting plate 11, and a plug-in component 12 is integrally formed at the bottom of the limiting plate 11. The plug-in component 12 passes through the limiting step 9 and is plugged into the inside of the second connecting component 10. The second connecting component 10 is annular, and the plug-in component 12 is threadedly connected to the second connecting component 10.

A protrusion 13 is integrally formed in the center of the top of the limiting plate 11, and the top of the protrusion 13 is located on the same horizontal plane as the top of the first cup cover 6.

[0032] Through the above technical solution, the second cup cover can be threadedly connected to the inside of the first cup cover 6. At the same time, after the second cup cover is installed, the protrusion 13 on the top is located at the same horizontal plane as the top of the first cup cover 6, so no extra space will be occupied.

[0033] In some other embodiments, a handle 7 is integrally formed on the outer side of the first cup cover 6 , so as to facilitate the staff to operate the first cup cover 6 and position the first cup cover 6 .

[0034] In combination with the above embodiments, when the device is used to dilute and stir sputum, the connector 4 of the stirring rod 14 is connected to the output end of the stirrer. After the stirring rod 14 is inserted into the cup body 1, the peristaltic pump is started to input the diluent into the stirring rod 14. The diluent directly enters the cup body 1 through the bottom of the stirring rod 14 to avoid splashing of the diluent.

[0035] After the diluent is loaded, the stirrer is started to drive the stirring rod 14 to rotate so that the sputum and the diluent are fully mixed;

[0036] After the mixing work is completed, the peristaltic pump is started to suck the mixed liquid out of the cup body 1. During this process, the staff will not come into contact with the sputum, thereby ensuring safety.

[0037] It should be noted that the output end of the mixer is also a hollow structure and is connected to the peristaltic pump.

[0038] The above description is only an embodiment of the present invention and is not intended to limit the present invention.
