Fig. 2 is the schematic diagram of lower cover plug and flexible connecting member provided by the utility model.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples.

As shown in Figure 1, a kind of biological material extraction element, including the tube body 1 with lumen and is located in the lumen A sampling swab 3, a partition panel 12 is provided in the lumen, lumen partition is not connected to mutually by the partition panel 12 Epicoele 11 and cavity of resorption, the upper opening being connected to the epicoele 11 is offered on the top of the tube body 1, in the upper opening Cooperation is equipped with a upper cover plug 4, is detachably connected the sampling swab 3 on one end that the upper cover plug 4 is located in the epicoele 11； The under shed being connected to the cavity of resorption is offered on the bottom of the tube body 1, cooperation is equipped with a lower cover plug on the under shed 7, it is intracavitary under described to be provided with extracting solution 2.

It is not to be connected to mutually that a partition panel 12, which is arranged, by lumen partition in the biological material extraction element in the tube body 1 Epicoele 11 and cavity of resorption, for being arranged the sampling swab 3, the cavity of resorption makes the epicoele 11 for the extracting solution 2 to be arranged It obtains the sampling swab 3 and extracting solution 2 is separately positioned in the different cavity body of same tube body 1, the two is avoided to connect before use It touches and soaks the swab head 31 for being broken the sampling swab 3.

Preferably, the partition panel is structure as a whole with the tube body.

When in use, after the upper cover plug 4 being taken out out of described epicoele 11 together with the sampling swab 3, institute is further taken out The lower cover plug 7 under shed is stated, before wiping sampling point, the sampling swab 3 is first dipped into the extracting solution 2, so that The swab head 31 draws enough extracting solutions 2；It is dipping the extracting solution 2 and then the lower cover plug 7 is got back into institute It states under shed；It completes after sampling, then the upper cover plug 4 is got back into the upper opening together with the sampling swab 2.

The sampling swab 3 is cotton stick swab or flocking swab, and swab head 31 is preferably flat, is easy to wiping and takes Sample；The sampling swab 3 is suspended in the epicoele 11.

It is attached between the lower cover plug 7 and tube body 1 by a flexible connecting member 8, the flexible connecting member 8 is being bent The plug of lower cover plug 7 can be made on the under shed after folding.

As shown in Fig. 2, the flexible connecting member 8 include a lantern ring 81 and both ends respectively with the lantern ring 81 and lower cover plug 7 One connection strap 82 of connection, the lantern ring 81 are sheathed on the outer wall of the lower opening of the tube body 1, and the connection strap 82 can be soft Property bending fold.The flexible connecting member 8 can prevent the lower cover plug 7 from accidentally losing after taking-up；Preferably, the connection Item 82 is structure as a whole with the lantern ring 81 and lower cover plug 7 respectively.

The upper cover plug 4 includes interconnecting piece 42 and handle portion 43, and the interconnecting piece 42 is located in the epicoele 11 for connecting The sampling swab 3 is connect, the handle portion 43 is located at outside the epicoele 11 for taking for user.

The interconnecting piece 42 connects the sampling swab 3 by inserting mode, with facilitate sampling after separate in the lab The sampling swab 3 is detected.

Preferably, there is an accommodating chamber 41 in the upper cover plug 4, the accommodating chamber 41 passes through the upper cover plug 4(interconnecting piece 42) several air holes on are connected to the epicoele 11, and are built-in with desiccant 5.

The desiccant 5 can quickly absorb the steam in the epicoele 11 by the air hole on the upper cover plug 4, protect Drying in the epicoele 11 is held, mildew and bacterial growth are prevented；The water-absorption material with humidity indicative function can be used in the desiccant 5 Material, such as discoloration silica gel are blue before water suction, start to change colour after water suction, when becoming pink, just no longer play dry work With, according to discoloration silica gel color, can judge before sampling its whether still effectively.

Preferably, the secondary opening of one be connected to the accommodating chamber 41 is offered on the top surface of the upper cover plug 4, the pair is opened Cooperation is equipped with a secondary lid plug 6 on mouth.

After the desiccant 5 water suction failure, the secondary lid plug 6 can be taken off from the secondary opening, then to institute The desiccant 5 stated in accommodating chamber 41 is replaced.

The tube body 1 is antistatic part, i.e., the described tube body 1 can be made or on its inner sidewall of antistatic material Coated with one layer of anti-static coating, to prevent Electrostatic Absorption and destroy the biological material extracted, and the outer surface of the tube body 1 It is upper that there is an at least plane, rolling when preventing from laying flat.Meanwhile the outer surface of the tube body 1 is frosting, passes through oil to facilitate Property connect on the outer surface of the tube body 1 record case information straight.

The above-mentioned embodiments merely express the embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention, as long as using the form institute of equivalent substitution or equivalent transformation The technical solution of acquisition, shall fall within the scope of the present invention.
