Description

Portable sampling tube for virus detection

Technical Field

The utility model belongs to the technical field of sampling pipe apparatus, concretely relates to a portable sampling pipe for handling virus detects.

Background

Generally, the method can be used for primarily detecting whether virus nucleic acid exists in vivo by a throat swab or a nose swab detection mode, and other medical technical means are required to be combined if further diagnosis is confirmed; wherein all need utilize virus sampling pipe when pharynx swab or nose swab sample collection, conventional virus sampling pipe includes the spiral cover of one end open-ended body and opening part, contains cell preservation liquid, utilizes the cotton swab to aim at patient's oral cavity pharynx portion or nasal cavity portion and samples, then unscrews the spiral cover of sampling pipe top, packs the cotton swab that finishes the sample into the body to the spiral cover is tightened in the lid. During the sampling process of the nasopharyngeal swab, aerosol carrying virus can be generated in the oral cavity or the nasal cavity of a patient, and particularly, cross contamination can easily occur during mixed detection. Because medical personnel all need with sample direct contact in sample collection process and testing process, when carrying out the spiral cover and open the body and put into the cotton swab, the cotton swab that previously put into in the body can lead to the risk of viral infection because of airborne is higher, and a large amount of spiral covers are not convenient for nucleic acid testing personnel and carry out the processing and the nucleic acid extraction of sample, on the other hand, the lid of conventional nasopharynx swab sampling pipe is relatively poor with the leakproofness of body, sample leakage and cross contamination's problem probably appears.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "front", "back", "upper", "lower", "left", "right", 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.

As shown in fig. 1 to 4, the present embodiment discloses a portable sampling tube for virus detection, which comprises a tube body 1, a sealing cover 2, an elastic layer 3 and a protrusion 4. The sealing cover 2 is in threaded connection with the outer side of the pipe orifice of the pipe body 1, the elastic layer 3 is made of elastic rubber skin with the thickness of 2.5mm and the shape of the circle, and the elastic rubber skin has good elastic deformation. Elastic layer 3 is fixed between the mouth of pipe of body 1 and sealed lid 2, the central point on sealed lid 2 puts the processing and has the circular shape trompil, protruding 4 is hemispherical shell, the edgewise processing has the positioning ring board 5 of extending outward in the bottom of protruding 4, with the internal surface of the protruding 4 of upper surface paste of elastic layer 3, thereby realize protruding 4 and fix the upper surface at elastic layer 3, the lower part processing at the interior perisporium of trompil has constant head tank and the cooperation of positioning ring board 5, thereby make protruding 4 can the clearance fit in the trompil. In order to improve the sealing between the positioning groove and the positioning ring plate 5, a sealing washer is provided on the surface of the positioning ring plate 5.

Two cuts 6 have been seted up in the position that is close to arch 4 on the surface of elastic layer 3, when not exerting down pressing force to arch 4, under the elasticity physical properties of elastic layer 3 self, cut 6 and be in closed state, when exerting down pressing force to arch 4, the edge of arch 4 then can produce the extrusion to elastic layer 3, leads to it to take place deformation, and two cuts 6 can be opened, conveniently stretches into inside with the cotton swab. When the protrusion 4 is released, the pressure of the protrusion 4 on the elastic layer 3 disappears, and the elastic layer 3 is reset, so that the cut 6 is automatically closed. In order to prevent the projection 4 from being touched by mistake due to the side turning of the box body for placing the sampling tube caused by bumping during transportation, the outer cover 7 can be connected to the outer wall of the tube body 1 in a threaded manner.

A portable sampling pipe concrete working process for handling virus detection as follows:

gather the worker singlehanded and press arch 4, the edge of arch 4 then can produce the extrusion to elastic layer 3, leads to it to take place deformation, cuts a mouthful 6 and can be opened, and the cotton swab that conveniently will accomplish the sampling stretches into inside through cutting a mouthful 6 and collects. When the protrusion 4 is released, the pressure of the protrusion 4 on the elastic layer 3 disappears, and the elastic layer 3 resets, so that the cut 6 automatically closes.

Compared with the sampling tube in the prior art, the utility model effectively saves the time for screwing the cover of the past sampling tube in the sampling process and improves the sampling work efficiency; compared with the prior art that the whole pipe orifice exposes air when the cover body of the sampling pipe is opened, the cotton swab is put in through the cut, so that the risk of infection to people caused by the prior cotton swab in the sampling pipe is greatly reduced; in the sample detection process, medical workers need to extract nucleic acid from a sample, and can independently finish sample adding operation by a single person and extract nucleic acid, so that the labor cost and the experiment operation time are greatly saved, the working efficiency of nucleic acid detection is effectively improved, the direct contact with the sample and the cross contamination between people and the sample and between the sample and the sample are avoided, and the detection efficiency is more efficient and faster. Under natural state, the opening is closed by the elastic layer, and the positioning groove with the hole is closed with the raised positioning ring plate, so that the leakage problem of the collected sample in the transportation and carrying processes can be effectively prevented.
