Description

Nucleic acid detection sampling device

Technical Field

The utility model belongs to the technical field of the epidemic prevention detects, specifically disclose a nucleic acid detects sampling device.

Background

In order to achieve the goal of dynamically clearing the number of new coronavirus infected persons in social areas such as communities and schools, an epidemic prevention leader group organizes and implements national nucleic acid detection according to the requirements of an epidemic prevention method, and generally implements a 'multi-person one-tube' detection mode according to quarantine requirements in consideration of detection efficiency and cost, namely, a plurality of person sampling samples are placed in the same test tube for storage and subsequent detection.

At present the sampling cotton swab that the conventionality carries out the sampling through the throat, its body of rod is all longer, can not directly put in and deposit in the sampling test tube, consequently need break with the unnecessary part in upper portion with the help of the crease on the body of rod, however current sampling test tube all is conventional ordinary test tube, even if predetermine under the condition of crease on the cotton swab body of rod, only carry out the screens with the help of test tube mouth end, its rupture operation is very inconvenient, consequently to this problem, the inventor has designed a neotype sampling test tube.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a nucleic acid detects sampling device to solve current sampling test tube and lack the structure that is used for the rupture sampling cotton swab body of rod and lead to awkward problem.

In order to achieve the above object, the basic scheme of the utility model is: a nucleic acid detection sampling device comprises a test tube, wherein an inner cover is coaxially and detachably connected in the upper part of the test tube and comprises a sleeve, a limiting ring is coaxially arranged on the upper part of the sleeve, a cap is coaxially connected on the upper part of the limiting ring, a round hole is coaxially formed in the upper part of the cap, one side, located on the round hole, of the upper part of the cap is provided with one or more clamping grooves communicated with the round hole, and the central line of each clamping groove passes through the center of the round hole; the outer cover is coaxially detachably connected to the outer side of the upper part of the test tube.

The working principle of the basic scheme is as follows:

be used for holding virus preservation liquid and sampling cotton swab in the test tube, the inner cup realizes coaxial detachable connection through the sleeve of lower part and the interior side of test tube upper port, when throwing in the sampling cotton swab to the test tube in, insert the test tube downwards in the round hole on the block with the cotton swab head portion earlier, and later with the cotton swab body of rod along the level to the draw-in groove of sliding in, draw-in groove upper portion is arranged in to the crease that makes on the cotton swab body of rod, the application of force is buckled the cotton swab body of rod and can be made it break from the crease, makes cotton swab head end one side fall into in the test tube simultaneously.

The beneficial effect of this basic scheme lies in:

(1) According to the scheme, the inner cover is detachably connected to the inner side of the upper opening of the test tube, and the clamping groove structure is arranged on the cover cap, so that the cotton swab rod body can be conveniently broken by means of the clamping groove structure, and therefore the efficiency of breaking operation of the cotton swab rod body is improved;

(2) Can dismantle the connection inner cup through the inside in the test tube upper port in this scheme, can appear tipping the condition in the test tube under, furthest prevents that the virus in the test tube from preserving the liquid and running off.

Further, a pull ring is hinged on the cap. The arrangement of the pull ring facilitates the opening of the inner cap.

Furthermore, one side of the upper part of the limiting ring, which is close to the cover cap, is of a sinking structure. The virus preservation liquid that sets up like this and enable to spill from round hole and draw-in groove is deposited temporarily in this intracavity that sinks, avoids it to ooze downwards along the test tube outer wall.

Furthermore, one side of the upper part of the limiting ring, which is far away from the cover cap, is of a groove structure. The groove is arranged at the position, so that the virus preservation solution splashed out can be guaranteed to be temporarily stored in the sinking cavity to the maximum extent.

Furthermore, the top is equipped with the gasket in the enclosing cover, screws up the enclosing cover after, and gasket lower part and block upper surface form sealed laminating.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: test tube 1, inner cup 2, sleeve 3, spacing ring 4, block 5, round hole 6, draw-in groove 7, enclosing cover 8, pull ring 9, formula of sinking structure 10, groove structure 11.

Examples as shown in figure 1, 2, a nucleic acid testing sampling device, including a test tube 1, test tube 1 upper portion inside is inserted with an inner cover 2, test tube 1 upper portion outside screw thread connection has an outer cover 8.

As shown in fig. 3 and 4, the inner cap 2 in this embodiment includes a sleeve 3, the sleeve 3 is in interference connection with the upper opening of the test tube 1, a limiting ring 4 is coaxially and integrally formed on the upper portion of the sleeve 3, a cap 5 is coaxially and integrally formed on the upper portion of the limiting ring 4, a sunken structure 10 is arranged on one side of the upper portion of the limiting ring 4 close to the cap 5, a groove structure 11 is arranged on one side of the upper portion of the limiting ring 4 far away from the cap 5, a circular hole 6 is coaxially processed on the upper portion of the cap 5, two clamping grooves 7 communicated with the circular hole 6 are processed on the upper portion of the cap 5, the two clamping grooves 7 are symmetrically arranged, and the center line of each clamping groove 7 passes through the center of the circular hole 6; a pull ring 9 is also hinged on the cap 5.

In addition, a gasket is arranged at the top in the outer cover 8, and after the outer cover 8 is screwed down, the lower part of the gasket is in sealing fit with the upper surface of the cap 5.

The specific implementation process is as follows:

before the sampling test tube 1 is used, the outer cover 8 is firstly opened, the inner cover 2 is simultaneously taken down through the pull ring 9, then a proper amount of virus preservation solution is injected into the test tube 1, and then the inner cover 2 and the outer cover 8 are respectively covered; in the nucleic acid sampling, open enclosing cover 8, the cotton swab head after will sampling is down, inserts test tube 1 in the round hole 6 on the bonnet 5 downwards, then with the cotton swab body of rod along the level to sliding in draw-in groove 7, make the crease on the cotton swab body of rod arrange draw-in groove 7 upper portion in, the application of force is buckled the cotton swab body of rod and can be made it break from crease department, and cotton swab head end one side falls into in test tube 1 simultaneously.

After the test tube 1 is filled with the sampling cotton swabs with the set number, the outer cover 8 is screwed down, the virus preservation liquid in the test tube 1 is often splashed outwards from the round hole 6 due to the bumping phenomenon in the transportation process, and the splashed virus preservation liquid is temporarily stored in a sinking cavity at the upper part of the limit ring 4 under the action of the groove structure 11 at the outer side of the limit ring 4, so that the virus preservation liquid is prevented from seeping along the threads outside the test tube 1 to the maximum extent; before the on-line detection, the outer cover 8 is opened, and the inner cover 2 is taken down by utilizing the pull ring 9.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
