Novel nucleic acid sampling tube and tube rack thereof

Technical Field

The utility model relates to a nucleic acid detects technical field, especially applicable full-automatic nucleic acid draws novel nucleic acid sampling pipe and pipe support of workstation.

Background

At present, the 10-mix-1 nucleic acid sampling tubes on the market all adopt simple tubular styles, meet the requirements of collection, transportation and the like, but do not consider the convenience of subsequent inspection, and hinder the feasibility of automatic sampling of a mechanical arm.

After 10 sampling throat swabs are put in, the plastic rod of the throat swab extends out of the liquid level in a messy way, and when an operator uses a pipette to remove the nucleic acid sampling liquid, the operator must carefully avoid the plastic rod of the throat swab and extend the gun head into the position below the liquid level to suck the liquid. And during imbibition, because the cotton material in pharynx swab bottom meets behind the nucleic acid sampling liquid, the inflation of absorbing water, very easily block up the rifle head, need operating personnel to aspirate repeatedly sometimes, guarantee the correct inspiratory capacity of liquid, bring inconvenience for operating personnel, influence work efficiency. Meanwhile, after the 10-mix-1 nucleic acid sampling tube is placed in a throat swab, the liquid level condition is difficult to unify, a pipette controlled by a mechanical arm is difficult to accurately avoid the throat swab, and meanwhile, the pipette head is not blocked, so that the real full automation of nucleic acid detection is difficult to realize, and the step also needs to depend on manual work during large-scale detection.

The utility model has the following contents:

in order to solve the problem, the utility model provides a novel nucleic acid sampling pipe and pipe support thereof.

The technical scheme of the utility model: the utility model provides a nucleic acid sampling pipe includes body and tube cap, the inside of body is separated for left cavity and the right cavity of bottom intercommunication through the baffle, sets up a plurality of round holes on the baffle, and the left and right sides of body bottom sets up the recess respectively.

In some specific embodiments, the nucleic acid sampling tube is detachably fixed on the tube frame, the tube frame is provided with a plurality of tube holes, the inner walls of the left side and the right side of each tube hole are respectively provided with a protrusion, and the nucleic acid sampling tube is clamped into the protrusions on the tube holes through the grooves.

In some embodiments, the bottom of the pipe body is in a horizontal structure, and the bottom of the inner cavity of the pipe body is in an arc structure.

In some embodiments, the length of the partition 3 is 7/10 to 9/10 of the depth of the inner cavity of the pipe body 1.

This novel design a novel nucleic acid sampling pipe and pipe support thereof sets up the baffle in the middle of its sampling pipe's inside, but sampling socle portion intercommunication. The round hole design is arranged on the clapboard, so that the uniformity of the nucleic acid sampling liquid on the two sides of the clapboard is ensured. The nucleic acid sampler can select to insert the pharyngeal swabs into one side of the pharyngeal swab in a concentrated way, and the other side is used for taking liquid in the nucleic acid detection experiment. The grooves are designed on two sides of the bottom of the nucleic acid sampling tube and are used together with a sampling tube rack with a matching clamping groove, the sampling tube can be fixedly placed in a directional mode, and samples can be located in the same direction during experiments.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a nucleic acid sampling pipe includes body and tube cap, and the inside of body is separated for left cavity and the right cavity of bottom intercommunication through the baffle, sets up a plurality of round holes on the baffle, and the left and right sides of body bottom sets up the recess respectively. The utility model discloses divide into pharynx swab input area and nucleic acid detection with nucleic acid sampling pipe and get the liquid district, operating personnel gets the liquid district imbibition at nucleic acid detection, avoids mixed and disorderly pharynx swab to hinder the liquid-transfering gun and go deep into below the liquid level, avoids the cotton part of pharynx swab to block up the rifle head and causes the imbibition volume inaccurate, has improved artifical detection efficiency greatly. Meanwhile, the standard nucleic acid detection liquid taking area is unified, feasibility is provided for liquid taking of a full-automatic mechanical arm, the full-automatic nucleic acid detection workstation is adapted, labor cost can be greatly saved, and nucleic acid detection efficiency is improved.
