Specific embodiment
The present invention provides a kind of excrement quantitative sampling device, simple in structure, and sampling is convenient, can not only quantitative sampling, moreover it is possible to
Protection liquid is completely dissolved into convenient for excrement.
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of excrement quantitative sampling device, and technical solution includes：
Thief rod 3, described 3 one end of thief rod are equipped with hollow cavity 4, and the outer wall of the hollow cavity 4 is equipped with and its phase
Logical through-hole 5；
Collecting pipe 2, the collecting pipe 2 are the tube body with opening, and the thief rod 3 stretches into or deviate from the tube body, institute
State the extension being equipped in tube body for being inserted into the hollow cavity 4.
It is using the advantageous effect of above-mentioned technical proposal：
Since 3 one end of thief rod in the present embodiment excrement quantitative sampling device is equipped with hollow cavity 4, the hollow cavity 4
Volume can be preset according to the requirement of sampling amount, thief rod more than 3 times, which is inserted into excrement and can realize in hollow cavity 4, fills up excrement
Just, then thief rod 3 is stretched into collecting pipe 2, equipped with protection liquid in collecting pipe 2, the process of collecting pipe 2 is stretched into thief rod 3
In, extension is gradually inserted in hollow cavity 4, is made between excrement via through holes 5 or extension and the hollow cavity 4 in hollow cavity 4
Gap squeezes out, and is sufficiently mixed with the protection liquid in collecting pipe 2.
Excrement quantitative sampling device has been discussed above includes thief rod 3 and collecting pipe 2, it is detailed with reference to Fig. 1 to Fig. 3
Two component expansion are described in detail in fine needle.
(1) thief rod 3
3 one end of thief rod is equipped with hollow cavity 4, which is used to acquire excrement, it can be understood as sampling cavity.
During thief rod 3 stretches into collecting pipe 2, one end equipped with hollow cavity 4 is first stretched into through opening in tube body.
The outer wall of the hollow cavity 4 is equipped with the through-hole 5 communicated therewith, and the quantity of through-hole 5 is unlimited, and shape is also not limited to
Circle shown in figure, the shape of hollow cavity 4 are also not limited to cylinder shown in figure, and through-hole 5 can be along hollow cavity 4
Outer wall is arranged in arrays, and excrement is facilitated to be discharged from different through-holes 5.
During collecting pipe 2 is stretched into, thief rod 3 gradually moves down thief rod 3 along the direction close to 2 bottom of collecting pipe,
Since extension corresponds to hollow cavity 4, then extension can be gradually inserted hollow cavity 4.The mistake of hollow cavity 4 is inserted into extension
Cheng Zhong makes gap between excrement via through holes 5 or extension and hollow cavity 4 be detached from hollow cavity based on extension and excrement interaction
Body 4, the protection liquid that excrement is made to be soluble in collecting pipe 2.
Stretching into or deviate from and the sealing of collecting pipe 2 for the ease of thief rod 3, the present invention can also include pipe lid 1,
The pipe lid 1 is connect with thief rod 3, and when thief rod 3 is finally stretched into collecting pipe 2, and lid closes the opening of collecting pipe 2.
(2) collecting pipe 2
Other than collecting pipe 2 discussed herein above is is additionally provided with extension in the tube body with opening and tube body, the extension
The shape of part can change according to actual needs, it is only necessary to meet extension be inserted into hollow cavity 4 during based on extension with
Excrement interaction makes gap between excrement via through holes 5 or extension and hollow cavity 4 be detached from hollow cavity 4.
The extension can extend along close to the direction of opening, the extension when hollow cavity 4 is stretched into through opening in collecting pipe 2
It is gradually inserted hollow cavity 4.Extension can be the solid cylinder structure 6 in Fig. 1；Can also be the cylindrical structure in Fig. 2, outside
Portion is equipped with helical member 7, and helical member twist, is equipped with groove between helical member and cylindrical structure；It may also be the cylinder knot in Fig. 3
Structure, outside are equipped with hairbrush 8.
As can be seen from FIG. 1, after thief rod 3 has taken excrement, as pipe lid 1 screws, excrement is in thief rod 3 and extension
It squeezes out from the through-hole of surrounding 5 under extruding, and is mixed with the protection liquid in collecting pipe 2.
As can be seen from FIG. 2, after thief rod 3 has taken excrement, as pipe lid 1 screws, excrement is skidded off from groove with pressure and is adopted
Sample chamber, and mixed with the protection liquid in collecting pipe 2.
As can be seen from FIG. 3, after thief rod 3 has taken excrement, as pipe lid 1 screws, excrement is skidded off under the extruding of hairbrush and is adopted
Sample chamber, protection liquid enter sampling cavity and are mixed with the inside excrement.
The shape of collecting pipe 2 is also not specifically limited, and can be cylindrical structure shown in figure.
By above description it is found that a kind of concrete structure of stool sampling device of the present invention can include pipe lid 1, thief rod
3 and collecting pipe 2, one end of thief rod 3 is equipped with pipe lid 1, and the other end is equipped with the hollow cavity 4 with through-hole 5, pipe lid 1 and collecting pipe 2
It can be threadedly coupled so that thief rod 3 is rotatable to be stretched into or deviate from collecting pipe 2, and the mistake for stretching into collecting pipe 2 is rotated in thief rod 3
Cheng Zhong, the extension on collecting pipe 2 are gradually inserted hollow cavity 4 so that excrement via through holes 5 or extension positioned at hollow cavity 4
Gap is detached from hollow cavity 4 between part and hollow cavity 4.It should be noted that pipe lid 1 and the connection mode of collecting pipe 2 are not limited to
In threaded connection, it also can directly fasten, be not specifically limited.
A kind of operation principle of stool sampling device of the present invention is：
Protection liquid is installed in collecting pipe 2, (sampling cavity at this time is finally inserted into liquid height for thief rod 3 higher than sampling cavity
Sampling cavity present position when in collecting pipe 2), specific dosage takes out thief rod 3, is held by pipe lid 1 depending on sampling cavity volume,
By more than 3 insertion excrement of thief rod until to sampling cavity is filled up, pipe lid 1 is then screwed again, until thief rod 3 finally stretches into collection
Pipe 2.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
The present invention is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to aforementioned each implementation
Technical solution recorded in example modifies or carries out equivalent replacement to which part technical characteristic；And these modification or
It replaces, the spirit and scope for various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution.
