Description

Double-cover sampling test tube

The technical field is as follows:

the utility model relates to the field of medical equipment, especially, relate to a double-cover sampling test tube.

Background art:

the virus sampling device that uses at present is mostly a test tube that seals up to have virus preservative fluid, plus the sampling swab of an independent packing. When the sample is collected, the handle part of the swab is held by hand, and the swab end is inserted into the sampling part to collect the biological sample. Then the sampling test tube cover sealed with the virus preservation solution is opened, the sampling swab head is inserted into the test tube, the sampling swab rod is broken off, and the test tube cover is tightly covered for storage and transportation.

When a liquid transfer device is used for sampling subsequently, due to the fact that broken sampling swab rods are different in length, the sampling swab rods are obliquely arranged in a test tube, a liquid taking suction head is difficult to enter the bottom of the test tube, the suction heads releasing liquid and extracting liquid are prone to touching a cotton swab of a sampling swab in the descending process, the tip of the suction head is blocked by the cotton swab, the liquid cannot be extracted, sampling failure is caused, and a detection result cannot be obtained; need the personnel of taking a sample to incline the test tube, expose the space of suction head sample and absorb the sample, easily with the liquid unrestrained in the test tube, contain the virus of high infectivity in the sample like the sample of sampling, can cause the hidden danger to the personnel's of taking a sample safety.

The utility model has the following contents:

an object of the utility model is to provide an effectively avoid sampling swab to hinder the double-deck sampling test tube that the pipettor absorbed the sample.

The utility model discloses by following technical scheme implement: a double-capped sampling tube comprising a tube and a tube cap; the test tube cap comprises a limiting sleeve and a sealing cap; the sealing cap is screwed on the pipe orifice at the top end of the limiting sleeve; the pipe orifice at the bottom end of the limiting sleeve is screwed on the pipe orifice of the test tube; more than three swab baffles are integrally and fixedly arranged on the inner wall of the limiting sleeve; the bottom ends of the swab baffles are fixedly connected into an integral structure; the bottom end of the swab clapboard is arranged below the liquid level of the virus preservation solution in the test tube; a liquid channel is formed between adjacent swab baffles.

Preferably, a plurality of the swab baffles are uniformly distributed and fixed on the inner wall of the limiting sleeve.

The utility model has the advantages that: compared with the prior art, the utility model discloses after the sampling is accomplished, leave pipettor sample space in the sampling test tube, avoid the pipettor suction head to touch the cotton swab, ensure successfully absorbing the sample, simple structure, convenient to use, low cost easily uses widely.

Description of the drawings:

fig. 1 is a schematic view of the entire structure of embodiment 1.

Fig. 2 is an overall schematic view of the position limiting sleeve.

Fig. 3 is a bottom view of fig. 2.

Fig. 4 is a top view of fig. 2.

FIG. 5 is a schematic diagram of the use of example 1.

The device comprises a test tube 1, a test tube cap 2, a limiting sleeve 3, a sealing cap 4, a swab clapboard 5, virus preservation liquid 6 and a sampling swab 7.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1: as shown in fig. 1 to 5, a double-cap sampling test tube comprises a test tube 1 and a test tube cap 2, wherein the test tube cap 2 comprises a limiting sleeve 3 and a sealing cap 4; the sealing cap 4 is screwed on the pipe orifice at the top end of the limiting sleeve 3; the pipe orifice at the bottom end of the limiting sleeve 3 is screwed on the pipe orifice of the test tube 1; six swab clapboards 5 are integrally and fixedly arranged on the inner wall of the limiting sleeve 3; the six swab baffles 5 are uniformly distributed and fixed on the inner wall of the limiting sleeve 3, and the bottom ends of the six swab baffles 5 are fixedly connected into an integral structure; the bottom end of the swab clapboard 5 is arranged below the liquid level of the virus preservation solution 6 in the test tube 1; a liquid channel 7 is formed between adjacent swab baffles 5.

Instructions for use: after a sample is collected by the handle part of the hand-held swab, the limiting sleeve 3 is screwed off from the test tube 1 sealed with the virus preservation solution 6, the cotton swab head of the sampling swab 7 is inserted into the test tube 1, the rod of the sampling swab 7 is broken, and the limiting sleeve 3 is screwed on the test tube 1 again in a rotating manner for storage and transportation; when the limiting sleeve 3 is screwed on the test tube 1 in a rotating way, the swab baffle 5 limits the sampling swab 7 between the swab baffle 5 and the inner wall of the test tube 1; the liquid channel 7 ensures that the virus preservation liquid 6 between the bottom ends of the swab baffles 5 is communicated with the virus preservation liquid 6 between the swab baffles 5 and the inner walls of the test tubes 1; during the sample, twist off sealed cap 4 from spacing sleeve pipe 3 top, the probe is reserved the pipettor sample space between 5 bottoms of swab baffle in the sampling test tube 5 and is drawed the liquid sample, avoids the probe to touch the cotton swab, ensures to successfully draw liquid.
