Description

Sample collector

Technical Field

The utility model belongs to the technical field of biochemical detection technique and specifically relates to a sample collector is related to.

Background

The sample detector that is used for sample detection such as saliva, sputum, serum at present uses more and more extensively. After a user wants to collect a sample, the sample preservation solution is isolated from the outside in the whole detection link, so that cleanness and convenience are guaranteed. At present, some testing instruments for saliva and other samples place preservation liquid in a collector and seal the preservation liquid by a film, after the sample enters the collector, a cover of the collector is covered, a sharp point is arranged on the inner side of the cover of the collector, after the cover of the collector is closed, the sharp point punctures the film, and the preservation liquid flows out and is mixed with the sample. In the mode of mixing the sample and the preservation solution, after the thin film is punctured, the thin film around the lacerated opening can block the preservation solution from flowing out, so that the preservation solution is easy to remain and cannot flow into the sample collector completely to be mixed with the sample. Therefore, the preservation solution cannot be quantified, which results in inaccurate detection effects in scientific research and clinical examination. In other detection instruments, the sample diluent is extruded out by extruding a container, however, the sample diluent is easy to overflow when the sample diluent is extruded too much, the sample is not loaded when the sample diluent is extruded too little, the amount of the added liquid cannot be quantified, and the operation is not convenient enough.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sample collector, it can make scientific research and clinical examination's detection effect accurate the time improve like the collection efficiency of samples such as sample, the sample collector of the invention's simple structure, convenient to use.

The utility model provides a technical scheme that its technical problem adopted is: sample collector, including upper and lower open-ended funnel, the articulated top cap in funnel upper portion, the opening on funnel upper portion can be sealed to the top cap, and the funnel lower part sets up stays the appearance test tube, stays appearance test tube and funnel intercommunication, and funnel inner wall bottom cooperation sets up the end cap, and the end cap can seal downwards and stay the opening of appearance test tube intercommunication.

Preferably, the lower part of funnel set up first internal thread, leave a kind test tube upper portion and set up the external screw thread, the funnel with leave a kind test tube threaded connection.

Preferably, the lower part of staying the appearance test tube set up the external screw thread, stay appearance test tube lower part threaded connection tube cap, the tube cap can be connected with the external screw thread fit who stays appearance test tube upper portion.

Preferably, the bottom of the funnel is provided with a second internal thread, the lower part of the plug is provided with an external thread, and the plug is in threaded connection with the funnel through hole.

Preferably, the plug is fixedly connected with one end of the pull ring.

Preferably, the funnel is provided with a protrusion so that it is snapped into the top cover.

Preferably, the outer wall of the sample holding test tube is provided with a plurality of horizontal marking lines.

The utility model has the advantages that: the utility model discloses a sample collector's the save quantitative preservative fluid of sample test tube storage, open the funnel stifled mouth that sets up, can put into samples such as saliva and leave the sample test tube, make the sample of collection mix with the preservative fluid. This kind of structure can make the efficiency that the sample was gathered uprise, convenient to use, and the sample directly flows in and stays the interior and preserve liquid mixture of appearance test tube, and the preservation liquid can not spill yet for scientific research and clinical examination's detection effect is accurate.

Detailed Description

Sample collector, as shown in fig. 1, including upper and lower open-ended funnel 1, the articulated top cap 2 in 1 upper portion of funnel, top cap 2 can seal the opening on 1 upper portion of funnel, and 1 lower part of funnel sets up stays a kind test tube 3, stays a kind test tube 3 and communicates with funnel 1, and the cooperation of 1 inner wall bottom of funnel sets up end cap 4, and end cap 4 can seal downwards and stay the opening 5 that kind test tube 3 communicates. Leave the interior storage quantitative of appearance in the test tube and preserve liquid, top cap 2 lifts the back, opens end cap 4, and the sample of gathering through funnel 1 is put into from opening 5 and is left the appearance test tube 3 in, makes the sample mix with preserving liquid. This kind of structure can make the efficiency that the sample was gathered uprise, convenient to use, and the sample directly flows in and stays the interior and preserve liquid mixture of appearance test tube, and the preservation liquid can not spill yet for scientific research and clinical examination's detection effect is accurate.

Specifically, the internal thread is seted up to the lower part of funnel 1, stays a kind test tube 3 upper portion and sets up the external screw thread, funnel 1 with stay a kind test tube 3 threaded connection. This kind of structure makes funnel 1 and leave a kind test tube 3 installation and dismantlement convenient.

Concrete, the external screw thread is seted up to the lower part of staying kind test tube 3, stays 3 lower part threaded connection tube caps 9 of kind test tube, and tube cap 9 can be connected with the external screw thread fit who stays 3 upper portions of kind test tube. This kind of structure can make tube cap 9 when funnel 1 with leave kind test tube 3 and be connected, installs in the lower part of leaving kind test tube 3, is difficult for losing. After the sample is being stayed a kind test tube 3 and is mixed with the preservative fluid, funnel 1 is dismantled with staying a kind test tube 3, at this moment unscrews tube cap 9 in the lower part of staying a kind test tube 3 to twist tube cap 9 on the upper portion of staying a kind test tube 3, make to stay a kind test tube 3 and seal all the time, avoid preserving the liquid and receive external pollution.

Specifically, set up the mark line of several levels on the outer wall of leaving a kind test tube 3. The structure is convenient for people to further determine the amount of the preserving fluid in the sample holding test tube 3 through the marking line on the sample holding test tube 3.

Specifically, one side of the top cover 2 is hinged with the upper part of the funnel 1, the funnel 1 is provided with a bulge 10 so as to be clamped with the top cover 2, and the structure can facilitate the lifting of the top cover 2.

Specifically, the funnel bottom is equipped with second

internal thread

7, and 4 lower parts of end cap are equipped with external screw thread 8, and 5 threaded connection of end cap 4 and funnel opening, when the sample collector uses with end cap 4 screw out can.

Specifically, the plug 4 may further include a plug 4 having one end fixedly connected to the pull ring 11, and the plug 4 may be pulled out by the pull ring 11.

The embodiments of the present invention have been described with reference to the accompanying drawings, but these descriptions should not be construed as limiting the scope of the present invention, and the technical contents not described in detail in the present invention are known in the art.
