Description

New coronavirus sampling tube

Technical Field

The invention relates to the technical field of sampling tubes, in particular to a novel coronavirus sampling tube.

Background

In these two years, new coronavirus has been abused and extremely infectious. Therefore, it is very important to avoid cross contamination when collecting specimens. At present, the collection sample is mostly through collecting bleeding such as blood, saliva or urine, however because the tube cap is detachable in the collection process, so sometimes the tube cap can drop, adorn the mistake easily and cause cross contamination at the in-process of going back the tube cap dress, lead to the testing result to make mistakes.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a novel coronavirus sampling tube, which is designed to ensure the sealing safety of the sampling tube and reduce the phenomenon of cross contamination among samples caused by the falling of a sealing cover.

The invention is realized by the following technical scheme:

the utility model provides a new corona virus sampling pipe, including the open inner tube in upper portion, the outer tube that is fixed with inner tube integrated into one piece and highly is less than the inner tube is established to the outside cover of inner tube, form the cushion chamber between inner tube and the outer tube, the inner tube is equipped with sealed lid in the outside cover of opening end, sealed covering install through adjustment mechanism can with the inner tube sealed complex of pegging graft have the piston, sealed covering is connected with first connecting band and second connecting band, first connecting band and outer union coupling, be equipped with a bayonet socket on the second connecting band, and through protruding joint of establishing on bayonet socket and the outer tube.

This scheme is connected sealed lid and sampling pipe's outward appearance through setting up first connecting band, gets when putting sealed lid when the sampling, sealed lid can not drop, conveniently installs with the sampling bottle cooperation again, simultaneously through the protruding cooperation joint on second connecting band and the outer tube, can take-up spacingly to sealed lid, prevents that it from breaking away from with the sampling bottle, prevents that the sample from overflowing.

Furthermore, adjustment mechanism includes the screw rod with sealed lid threaded connection, and the top of screw rod outside sealed lid is provided with the carousel, and the bottom of screw rod in sealed lid is rotated and is installed the fixed plate, and the fixed plate has the clamp plate through spring coupling.

The screw rod rotates through the carousel, and the accessible rotates to push down the fixed plate application of force, and the fixed plate passes through the spring to the clamp plate application of force for the clamp plate exerts the effort to the piston, and the spring can play the cushioning effect simultaneously, guarantees to provide suitable effort to the piston and is unlikely to impress the piston in the inner tube completely.

Furthermore, two ends of the fixed plate are respectively rotatably provided with a first connecting rod, two ends of the pressing plate, which are opposite to the fixed plate, are respectively rotatably provided with a second connecting rod, and the free end of the first connecting rod is rotatably connected with the free end of the second connecting rod.

Through rotating first connecting rod of installation and second connecting rod between fixed plate and clamp plate, can carry on spacingly to the spring for the clamp plate can reciprocate vertically, presses the application of force to the piston, in order to guarantee the leakproofness of piston to the inner tube.

Preferably, the piston is of a reverse conical shape.

The back taper and the inner tube are connected in an inserting mode, the sealing performance is increased continuously when the force is applied in a pressing mode, and the sealing performance of the sampling tube is improved.

Furthermore, an elastic plug positioned below the piston is inserted in the inner tube, and a cross-shaped opening is formed in the center of the elastic plug.

Through set up an elastic plug and set up the cross opening in the inner tube, can carry out the first layer to sealed to the sample of intraductal, when not receiving external force, the cross opening is close to closed state, effectively prevents the sample outwards diffusion, protection operating personnel's safety.

Furthermore, two lugs are symmetrically arranged on the outer side of the outer pipe.

Set up the lug through the outside at the outer tube, can make things convenient for operating personnel to hold between the fingers and hold, guarantee to get the stability of putting the sampling pipe.

The invention has the beneficial effects that:

a buffer cavity is formed between the inner tube and the outer tube, so that the inner tube is protected, the sample is not easy to extrude and break in the transportation process, the overflow is avoided even after the extrusion and the breaking, the biological safety risk of the virus to the environment in the sampling, transportation and storage processes is reduced, and the sample leakage and secondary pollution are avoided.

Carry out the shutoff through the piston to the inner tube, prevent that the collection sample from flowing, cooperation adjustment mechanism utilizes the clamp plate to exert the holding down force to the piston through rotating the screw rod for keep sealed between piston and the inner tube, promote holistic leakproofness, first connecting band will seal the lid and be in the same place with the outer tube connection, make sealed lid and sampling pipe one-to-one, can avoid sealed lid to drop because of the buckle closure causes cross contamination between the different samples. The second connecting band is buckled with the bulge on the outer tube through the buckle, so that the sealing cover can be effectively fixed.

The elastic plug with the cross opening is arranged below the piston, the pipettor can be inserted, the elastic plug enables the cross opening to be in a closed state under the elastic action after sampling, aerosol is prevented from escaping, the sampling pipe is sealed after the elastic plug is matched with the piston to compress, the safety of operators can be effectively protected, and the use safety is improved.
