Specific implementation mode

The technical issues of to make the utility model solve, the technical solution of use and the technique effect that reaches are clearer, Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.It is understood that Specific embodiment described herein is used only for explaining the utility model, rather than the restriction to the utility model.In addition it also needs It is noted that illustrate only for ease of description, in attached drawing with the relevant part of the utility model and it is not all.

First embodiment

Fig. 1 is the structural schematic diagram of resampling filter device provided in this embodiment, including sampling apparatus 2, Sample preservation pipe 1 And filter device, Sample preservation pipe 1 are provided with accommodation space 11, filter device are provided in accommodation space 11, and fill in filtering Filter hole is offered on the side wall set, sampling apparatus 2 is plugged in filter device, and filter device is set to Sample preservation pipe 1 On inner wall.By being provided with filter device in Sample preservation pipe 1, the collected object to be detected of sampling apparatus 2 is effectively protected It stays in filter device, subsequent other compositions will be diffused into Sample preservation pipe 1, prevent automatic moving liquid plant or craft Blocking is contacted between pipettor and object to be detected or sampling head, caused by draw solution have some setbacks, the bad control of uptake is asked Topic, improves extraction efficiency and working efficiency.

Specifically, in the present embodiment, filter device is filtration membrane 3, filtration membrane 3 is to be detected for filtering liquid Object is provided with supporting rack in the outside of filtration membrane 3, filtration membrane 3 is fixedly mounted on supporting rack, is then consolidated supporting rack Due in Sample preservation pipe 1.The first filter hole 31 is provided on filtration membrane 3, the first filter hole 31 herein referred to is in naked eyes In the case of it is invisible, filtration membrane 3 can filter the molecule or albumen of different molecular weight size, can be wanted as needed Molecular size range molecule or albumen, polypeptide etc., filtration membrane 3 can be replaced as needed certainly, and then filter Obtain the molecule of different molecular weight size.Meanwhile being conducive to selectively filter, purification of target object, the sample purity of absorption Higher, impurity interference are reduced.

Meanwhile sampling apparatus 2 includes thief rod 21 and sampling head 22, sampling head 22 is set to one end of thief rod 21, profit Liquid or solid tissue substance is acquired with sampling head 22, liquid tissue object here can be urine, sputum, blood etc., Solid can be excrement, various food and sample etc., and then the sampling apparatus 2 after acquisition is placed in filter device, carry out Filtering.Sampling apparatus can be all kinds of sample-taking brushs, swab, small spoon etc..

It is arranged as shown in Figure 1, the top of filtration membrane 3 is concordant with the top of Sample preservation pipe 1, sample can also be less than and protected The top for depositing pipe 1 is placed, and the lower part of filtration membrane 3 is connect with the lower seal of Sample preservation pipe 1.By by filtration membrane 3 Bottom and the sealed bottom of Sample preservation pipe 1 are arranged, and can carry out good filtering to the substance of 3 lower part of filtration membrane, prevent Miss that some diameters are big or not conceivable molecule.A sealing cover is also needed in the top of Sample preservation pipe 1 (in figure not Show), so that the top to Sample preservation pipe 1 covers.

Specifically, in the present embodiment, filtration membrane 3 and Sample preservation pipe 1 are integrally formed setting, by filtration membrane 3 It is set as circular tube shaped, since the molecule that circular tube shaped is more conducive in filtration membrane 3 is diffused around, meanwhile, it will filter Film 3 is arranged to circular tube shaped, the connection being more conducive between filtration membrane 3 and Sample preservation pipe 1, while also improving filtering The space availability ratio of film 3, the shape that certain filtration membrane 3 can also do camber, cross section is quadrangle, in the present embodiment The shape of filtration membrane 3 is not limited.

As shown in Fig. 2, for the vertical view of resampling filter device another kind structure, specifically, on 1 inner wall of Sample preservation pipe Then two sides of filtration membrane 3 are mounted in holding tank, it can be seen from the figure that by opposite holding tank there are two being arranged, Filtration membrane 3 is bent camber, and filtration membrane 3 and the inner wall of Sample preservation pipe 1 form the sky that can place sampling apparatus 2 Between.Due to being detachably connected for filtration membrane 3 and Sample preservation pipe 1, so according to actual filtration needs, it can be thin to filtering Film 3 is replaced, convenient and practical.

Further include pipettor 4 in the present embodiment, pipettor 4 is set to the top of Sample preservation pipe 1, and pipettor 4 includes moving Liquid pipette tips 41.Draw preserve pipe liquid when, liquid transfer gun head 41 can stretch into preserve pipe in, when filtration membrane 3 is arranged, need by The area of section control of filtration membrane 3 in a certain range, prevents pipettor 4 in draw solution, by the dry of filtration membrane 3 It relates to, influences extraction efficiency.

Second embodiment

Fig. 2 shows second embodiments, wherein identical with first embodiment or corresponding parts use and first The corresponding reference numeral of embodiment.For simplicity, the distinctive points of second embodiment and first embodiment are only described.Area Place is not, in the present embodiment, filter device is screen pipe 30, and the lower section of screen pipe 30 is provided with the second filter hole 301, The purpose of screen pipe 30 is to filter some macroscopic solid tissue's objects or excreta, since solid feces are in itself weight Lower section can be deposited under the action of power, so obstructing solids in screen pipe 30 using the second filter hole 301, prevent solid The liquid transfer gun head 41 of tissue substance and pipettor 4 blocks, naturally it is also possible to prevent sampling apparatus 2 and shifting during absorption liquid Liquid pipette tips 41 are in contact, and block liquid transfer gun head 41, are influenced and are drawn work and uptake.

Specifically, in the present embodiment, slideway being provided on the inner wall of Sample preservation pipe 1, cunning is provided on screen pipe 30 Block, sliding block are slidably connected with slideway.It is connected, very easy screen pipe 30 can be taken by sliding block and slideway Go out and be put into, by screen pipe 30 residue and solid feces pour out, being also convenient for the later stage cleans screen pipe 30.Together When, screen pipe 30 is made of glass or resin material, can be more conducive to and be cleaned to screen pipe 30, certainly due to The transparent characteristic of glass also allows for carrying out good observation to the situation in screen pipe 30.

Specifically, in the present embodiment, screen pipe 30 can be made of two kinds of materials, the part that sliding block is arranged uses hard Material, such as resin, glass, remaining part (the mainly lower part of screen pipe 30) are then thin using the filtering with filtering function Film is made, and the screen pipe 30 with filtering function is mounted in Sample preservation pipe 1.Then the filterability of filtration membrane is utilized Can, liquid tissue object can be filtered.

Embodiment of above is to elaborate the basic principle and characteristic of the utility model, and the utility model is not by above-mentioned reality The mode of applying limits, and on the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes, These changes and modifications are both fallen in claimed the scope of the utility model.The utility model requires protection scope is by appended Claims and its equivalent thereof.
