Description

sample processing tube

technical field

The utility model relates to the technical field of medical appliances, in particular to a sample processing tube.

Background technique

Sample testing is very important clinically. The results of the test can directly reflect the pathological phenomenon of the patient and indirectly judge the functional status of human organs. At present, the detection of clinical samples (taking the detection of stool samples as an example) mainly adopts the following two methods: one is to use a container to directly collect a part of the stool sample and put it in the container for inspection, and the laboratory uses bamboo sticks and other objects after receiving the sample Pick a part of the stool for smear microscopy. The other is to use a sampling stick to take a feces sample, then insert the sampling stick with the feces sample into the diluent for dilution, and test the diluent in which the feces sample is dissolved.

However, because samples such as feces contain particles and impurities, the above two methods are used for detection, and the particles and impurities will affect the test results, which is not conducive to accurate judgment of the patient's condition. In addition, the adoption of the above two methods also has the problems of serious pollution of environmental sanitation due to poor sealing, easy diffusion of peculiar smell, and even leakage of liquid.

Utility model content

The utility model provides a sample processing tube which can effectively remove the particles and impurities in the sample to be tested in order to overcome the problem that particles and impurities interfere with the inspection results in the existing sample inspection.

The tube body is used to hold the diluent. The pipe cap is detachably connected to one end of the pipe body, and the pipe cap has a water outlet hole communicating with the inside of the pipe body. The cover is detachably connected to the tube cap and covers the water outlet hole on the tube cap. The sampling rod has a threaded sampling area, and the sampling rod extends into the inside of the tube body to dissolve the sample to be tested on the threaded sampling area into the diluent in the tube body. At least one filter membrane is arranged in the tube cap and is located on the side of the outlet hole close to the tube body, and the diluted solution dissolved with the sample to be tested flows out from the outlet hole after being filtered by at least one filter membrane.

In one embodiment of the present invention, the sampling rod is connected with the inside of the cap.

In an embodiment of the present invention, the outer wall of the cap has anti-skid lines.

In an embodiment of the present invention, the sample processing tube further includes a gasket, which is disposed in the tube cap and located on a side of at least one filter membrane close to the tube body.

In one embodiment of the present invention, the gasket is a silicone ring.

In an embodiment of the present invention, when the filter membrane has more than two layers, the pore size of the filter membrane gradually becomes smaller along the outflow direction of the diluent in which the sample to be tested is dissolved.

To sum up, compared with the prior art, the sample processing tube provided by the utility model has the following advantages:

The sample to be tested is obtained through a sampling rod with a threaded sampling area, the sampling rod is inserted into the inside of the tube body, and the sample to be tested is dissolved in the diluent in the tube body. The diluent containing the sample to be tested is filtered through at least one filter membrane to remove particles and impurities, and then flows out from the water outlet hole on the cap for detection. The sample processing tube provided by the utility model adopts a filter membrane to remove the particles and impurities in the sample to be tested, avoiding the interference of the particles and impurities on the detection results, and greatly improving the detection accuracy. By placing the diluent inside the tube body and setting a cap with a gasket on the tube body, liquid leakage and odor diffusion can be effectively prevented.

In addition, in order to facilitate the collection of samples to be tested, a sampling rod is set to be connected to the inside of the cap, and the user can hold the cap to obtain the sample to be tested. Further, when the number of filter membranes is two or more than two layers, the pore size of the filter membranes is gradually reduced along the outflow direction of the diluent in which the sample to be tested is dissolved. This setting can not only effectively block the escape of fine particles and impurities in the diluent in which the sample to be tested is dissolved, but also has a better supporting effect on the multi-layer filter membrane.

In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments will be described in detail below together with the accompanying drawings.

Detailed ways

As shown in FIGS. 1 and 2 , the sample processing tube provided in this embodiment includes a tube body 1 , a tube cap 2 , a cover 3 , a sampling rod 4 , at least one filter membrane 5 and a gasket 6 . The tube body 1 is used to hold the diluent, the sampling rod 4 is connected with the tube cap 2, the tube cap 2 is detachably connected to one end of the tube body 1, and the tube cap 2 has a water outlet connected with the inside of the tube body 1 twenty one. The cover 3 is detachably connected to the cap 2 and covers the outlet hole 21 on the cap 2 . At least one layer of filter membrane 5 is arranged in the cap 2 and located on the side of the outlet hole 21 close to the tube body 1 .

In this embodiment, both the cap 3 and the tube cap 2 and the tube cap 2 and the tube body 1 are connected through internal threads and external threads. That is, the disassembly or connection between the cover 3 and the cap 2 can be realized by rotating the cover 3 . Similarly, the disassembly or connection between the tube cap 2 and the tube body 1 can be realized only by rotating the tube cap 2 .
