The specific embodiment

Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.

Embodiment

Shown in Fig. 1～3, the utility model mainly is made up of body 1, and said body 1 one ends have the chamber that opening and its inside have the storage of specimens sample.In body 1 that the sample sample is packed into, said body 1 is also supporting to have the pipe spoon 2 that dips the sample sample.During use, through this pipe spoon 2 the sample sample is scooped in the body 1 and deposits.Sample sealing for the ease of leaving in the body 1 is preserved; To prevent sample, simultaneously the sample sample is filtered, to improve the precision of test result by external environmental; On said body 1, also be provided with the sealing filter that is connected with the openend of body 1, as shown in Figure 1.

Said sealing filter comprises the black box of closed tube 1, and the sealing assembly then is connected on the body 1.Said black box comprises an end opening and inner sealing-plug 3 with cavity 4; For the ease of using the blind end of needle pierces sealing-plug 3; Thereby draw the sample sample of depositing in the cavity 4; Said sealing-plug 3 is formed by the material that is easy to puncture, and present embodiment preferentially selects for use silica gel to be made.For the ease of being connected with body 1, on said sealing-plug 3, also be provided with end cap 5, said end cap 5 inner hollow and be complementary with sealing-plug 3, this end cap 5 be enclosed within on the sealing-plug 3 after sealing-plug 3 cooperates.On said end cap 5, also be provided with internal thread 7, simultaneously, then be provided with the external screw thread 6 that is complementary with internal thread 7 at the openend of said body 1, said end cap 5 through its internal thread 7 be connected on the body 1 after external screw thread 6 cooperates, as shown in Figure 1.

Said sealing filter also comprises filter assemblies, and this filter assemblies comprises filtration body 9.For the ease of filtering, said filtration body 9 has through hole 8, and the inlet 11 of this through hole 8 is arranged on the sidewall that filters body 9, and the outlet 12 of this through hole 8 then is arranged on the end face that filters body 9 one ends, and is as shown in Figure 3.On the inlet 11 of said filtration body 9, also be provided with screen pack 10; For the ease of connecting screen pack 10; On said inlet 11, be provided with the draw-in groove 15 that is complementary with screen pack 10, said screen pack 10 with snap in the draw-in groove 15 after draw-in groove 15 cooperates, filter on the body 9 thereby be fixed on.Outlet 12 1 ends of said through hole 8 match with sealing-plug 3; Said sealing-plug 3 openings one end then stretches into through hole 8 inside through the outlet 12 of through hole 8; And sealing plug 3 be connected on the hole wall of through hole 8 after through hole 8 cooperates, promptly the cavity 4 of sealing plug 3 is connected with through hole 8.For the impurity in the better filtering sample sample; Also be provided with the aided filter net 13 that is positioned at sealing-plug 3 openends in said through hole 8 inside; The mount that said aided filter net 13 passes through sealing-plug 3 and filters body 9 is between sealing plug 3 and filtration body 9, and the mesh diameter of this aided filter net 13 is less than the mesh diameter of screen pack 10.

Simultaneously, said filtration body 9 also matches with end cap 5, and said end cap 5 filters on the body 9 with filtering to be enclosed within after body 9 cooperates, thereby makes overall structure of sealing filter formation, and is as shown in Figure 2.For the ease of sealing, on said filtration body 9, also be provided with sealing ring 14, thereby prevent that the sample sample from leaking through the gap of filtering between body 9 and the end cap 5.Said sealing ring 14 is made by soft material, and the utility model preferentially selects for use silica gel to be made.For the ease of using, said pipe spoon 2 is fixed on the other end that filters body 9, and with filter body 9 structure that is solidified as a whole.

During use, screw out end cap 5, take off thereby will seal filter through the threaded engagement between end cap 5 and the body 1, and take-off pipe spoon 2.Through pipe spoon 2 the sample sample is scooped in the body 1, again with end cap 5 through being connected after the threaded engagement on the body 1, thereby the sealing of sample sample is kept in the body 1.As required, also can in body 1, add cell-preservation liquid, be beneficial to preserve the sample sample.Be inverted body 1 then; It is downward to be about to body 1 opening one end; The sample sample is lowered into the body openend in the gravity effect, and flows in the through hole 8 through the inlet 11 that filters body 9, and the residue under the effect of screen pack 10 in the sample sample then is intercepted in the body 1.The sample sample that flows in the through hole 8 continues to sink; And flow in the cavity 4 of sealing-plug 3; And the sample sample further is filtered under the effect of aided filter net 13 when in through hole 8, flowing to cavity 4; Thereby the tiny residue interception in the sample sample in through hole 8, is made to get in the sample sample tested in the cavity 4 not contain or contain a spot of tiny residue, thereby makes the testing result of sample sample more accurate.During test, only need to pass the sample sample that sealing-plug 3 can draw in the cavity 4 and detect, and do not need to open again end cap 5, thereby once more the sample sample is exposed in the air can prevent to test the time and makes the sample sample by external environmental through syringe needle.

As stated, just can realize the utility model preferably.
