Embodiment 1

[0032] refer to Figure 1-Figure 4 , a one-piece opening and closing dripper coupling device, which is detachably arranged at one end of the nozzle of the sampling tube 1, and includes a screw structure 2, a dripper structure 3 and a sealing structure 4; the screw structure 2 It is detachably arranged at one end of the nozzle of the sampling tube 1; the dripper structure 3 is arranged on the screw structure 2, and the dripper structure 3 includes a The liquid guide part 31 at one end is arranged on the liquid outlet part 32 at the end of the liquid guide part 31 away from the sampling tube 1, and the arc protrusion 33 on the outer wall of the liquid guide part 31 is arranged on the said liquid guide part 31. The outer wall of the liquid guide part 31 is away from the sealing structure connection part 34 on the side of the arc protrusion 33; the sealing structure 4 is fixedly connected to the sealing structure connecting part 34, and the sealing structure 4 includes, The plug ...

Embodiment 2

[0041] refer to image 3 , on the basis of Example 1, in order to prevent the sample solution from overflowing from the plugging structure 4, as a further improvement, a protrusion 46 is also set on the plug 43, and the protrusion 46 is placed on the plugging structure 4 When the liquid outlet part 32 is blocked, it is adapted to the inner diameter of the liquid outlet end of the liquid outlet part 32 .

Embodiment 3

[0043] refer to Figure 4 , on the basis of Embodiment 1, the liquid outlet 32 ​​is a conical soft body structure, the inner wall of the liquid outlet 32 ​​is provided with a protrusion near the side of the liquid guide part 31, and the structure of the plug 43 is also Including, an extruding part arranged at the position where the inner wall of the plug cover 41 cooperates with the liquid outlet part 32, and the plug 43 is arranged at an end of the extruding part away from the opening 45 of the plug cover 41; The extrusion part is a cylindrical cavity, and the inner diameter of the extrusion part is the same as the minimum outer diameter of the liquid outlet part 32; when the sealing structure 4 blocks the liquid outlet part 32, the The squeezing part squeezes the liquid outlet part 32, and the protrusions are close to each other to form a seal.

[0044] By squeezing the protrusions close to each other to form a seal, when the plugging structure 4 blocks the liquid outlet 32...

Abstract

The invention discloses a one-piece opening and closing type dropper pipe connecting device which is detachably arranged at one end of a pipe opening of a sampling pipe and comprises an integrally-formed screw structure, a dropper structure and a blocking structure. The screw structure is detachably arranged at one end of a pipe opening of the sampling pipe; the dropper structure is arranged on the screw structure and comprises a liquid guide part arranged at one end, far away from the sampling tube, of the screw structure, a liquid outlet part arranged at one end, far away from the sampling tube, of the liquid guide part, an arc bulge arranged on the outer wall of the liquid guide part, and a blocking structure connecting part arranged on one side, far away from the arc bulge, of the outer wall of the liquid guide part; the blocking structure is fixedly connected to the blocking structure connecting part and comprises a plug cover fixedly connected to the blocking structure connecting part, a clamping ring arranged on the outer wall of the plug cover and a plug arranged in the plug cover, the inner wall of the plug cover is matched with the outer wall of the water dropper structure, and the clamping ring is matched with the arc protrusion when the liquid outlet part is blocked by the blocking structure; and the plug is matched with the liquid outlet end of the liquid outlet part when the liquid outlet part is plugged by the blocking structure.

Description

technical field [0001] The invention relates to the field of sampling tube fittings, in particular to a one-piece opening and closing dripper coupling device. Background technique [0002] In the process of target analytes in medical testing, the target analytes need to be collected from the organism or attachment, collected, and transported to a designated location for detection and analysis. Different target analytes have different sampling and collection methods, and there are specific requirements for sample storage, transportation and testing to ensure the representativeness, safety and reliability of the results, so as to achieve the purpose of analysis and testing. [0003] The method of collecting target analytes on the surface of human skin, mucous membranes, and cavities is usually to wipe the corresponding parts with a swab, and then place the swab in a sample collection tube and stir to dissolve and analyze the sample. The sample collection tube is temporarily o...
