Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

It should be understood that the structures, ratios, sizes, and the like shown in the drawings are only used for matching the disclosure of the present disclosure, and are not used for limiting the conditions of the present disclosure, so that the present disclosure is not limited to the technical essence, and any modifications of the structures, changes of the ratios, or adjustments of the sizes, can still fall within the scope of the present disclosure without affecting the function and the achievable purpose of the present disclosure. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

As can be seen from fig. 1 and 2, the medical sampling bottle provided by the present invention comprises a bottle body 1, a bottle cap 3 and a sample separating member 2; the bottle cap 3 is detachably connected with the bottle body 1; the sample separator 2 comprises a diaphragm 21, and the diaphragm 21 is arranged in the bottle body 1; the diaphragm 21 is provided with a circular hole 24 in the center for stripping off the sample on the sampler. The sample separator 2 further comprises a clamping portion 22 and a connecting portion 23 connecting the septum 21 and the clamping portion 22; the clamping portion 22 is sleeved on the outer edge of the bottle mouth of the bottle body 1.

As can be seen from fig. 3, in the medical sampling bottle provided by the present invention, the septum 21 is circular, and the center of the septum 21 is provided with a circular hole 24; the round hole 24 can be used for inserting the sampler, so that cells on the surface of the sampler fall off and enter the sample preservation solution, and the mucus is difficult to separate from the surface of the sampler due to the fact that the rectum is rich in mucus, particularly if the rectum has tumors, and the mucus which is not easy to fall off on the sampler is scraped under the tension action of the round hole 24.

In the present invention, as shown in fig. 1, the diameter of the diaphragm 21 is the same as or slightly smaller than that of the bottle 1; preferably, the diameter of the diaphragm 21 is the same as the diameter of the bottle body 1.

As shown in fig. 1, in the medical sampling bottle provided by the present invention, a sample preservation solution 4 is disposed in the bottle body 1; in the preferred embodiment of the present invention, the liquid level of the sample preservation solution 4 is higher than the membrane 21, so as to prevent mucus on the sampler from splashing during the peeling process, and reduce the risk of infection of medical personnel.

In the utility model, the bottle body 1 and the bottle cap 3 are connected through threads or buckles.

In some preferred embodiments of the present invention, a sealing member is provided in the bottle cap 3, and the sealing member enables the bottle cap 3 to be connected to the bottle body 1 to achieve a sealing effect, thereby preventing liquid from leaking out when the sample storage bottle is shaken.

In some preferred embodiments of the present invention, the diaphragm 21 is made of latex, and has good elasticity and is easily restored to its original shape.

In the present invention, the diameter of the circular hole 24 is set to be suitable for insertion of a sampler. In some preferred embodiments of the present invention, the diameter of the circular hole 24 is 0.5cm, which is adapted to the diameter of the sampler of 0.3-0.5 cm, so as to facilitate the insertion of the sampler into the sample holding bottle.

In some preferred embodiments of the present invention, as shown in FIG. 1, the bottle body 1 has a diameter of 5cm and a height of 18 cm; the distance between the diaphragm 21 and the bottom of the bottle is 11cm, and the liquid level height of the sample preservation solution 4 is 12cm and is 1cm higher than the diaphragm 21.

The utility model can be used in combination with a rectal sampling brush disclosed in patent document CN 211560170U.

The working principle is as follows: when the medical sampling bottle is used, as shown in fig. 1, the clamping part 22 of the sample separating piece 2 is sleeved on the outer edge of the bottle opening of the bottle body 1, the diaphragm 21 of the sample separating piece 2 is sleeved on the inner wall of the bottle body 1, the connecting part 23 of the sample separating piece 2 is attached to the inside of the bottle body 1, and at the moment, the diaphragm 21 is positioned 1cm below the liquid level of the sample preserving fluid 4; the sampler after sampling is aligned with the round hole 24 in the center of the diaphragm 21 and inserted into the sample storage bottle, the sampler is repeatedly shaken (when the sampler is matched with a rectal sampling brush, the inflatable air bag is repeatedly expanded by extruding the inflatable part) to ensure that cells attached to surface villi fall off, then the clamping part 22 on the outer edge of the bottle mouth of the bottle body 1 is pressed by hand, the sampler is pulled out under the condition that the sampler is in a vertical state (when the sampler is matched with the rectal sampling brush, the inflatable air bag is in an original state), and mucus which is not easy to fall off on the sampler is stripped off by utilizing the tension of the round hole 24 in the center of the diaphragm 21; since the diaphragm 21 is located below the liquid level of the sample-preserving fluid 4, mucus does not splash when the sampler is pulled out; then the cover 3 is covered, and the sample storage bottle is shaken to ensure that the mucus on the membrane 21 in the bottle body 1 enters the storage solution; during detection, the sample separator 2 is taken out, liquid above the diaphragm 21 can flow down from the round hole 24 in the center of the diaphragm 21, sample loss can be avoided, and the accuracy of a detection result is improved.

The medical sampling bottle provided by the utility model can effectively solve the problems that a sample on a sample collector is difficult to separate in the collection process of an anal swab, mucus is easy to splash in the stripping process and the like, avoids sample loss, reduces the medical infection risk, simplifies the sample collection and preservation steps of novel coronavirus, effectively reduces the missed diagnosis rate and has high industrial utilization value.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
