On can be matched with bar 20 is moved back, be oriented to moving back bar 20, to improve move back bar 20 movement stability.
Embodiment two
As shown in fig. 4-5, the present embodiment provides a kind of stool collection devices, are provided with any of the above-described stool sampling
Device.
The stool collection device has all technique effects of above-mentioned dejecta sampling device.
Particularly, stool collection device further includes storage bottle, and storage bottle has stored vial 41 and storage bottle cap, storage
Bottle cap is removably connect with stored vial 41, and there is storage bottle storage bottleneck 42, the internal diameter of storage bottleneck 42 to be more than sampling head
Outer diameter, stored vial 41 being capable of integrally contained sampling head.
By the way that stored vial 41 and storage bottle cap is arranged, the sample acquired to sampling head 30 can be realized using storage bottle
Storage.The internal diameter size for storing bottleneck 42 is set greater than to the outer diameter of sampling head simultaneously, not only facilitates storage sampling head, and
And can make sampling head during being put into stored vial 41, it will not be touched with the edge of storage bottleneck 42, institute
With the sample accompanying by sampling head outside, it can also enter in storage bottle with sampling head, stored without falling completely
The outside of bottleneck 42 avoids generating the adverse effect in vision and the sense of taste.
Further particularly, it is filled with Sample preservation liquid in stored vial 41.
The filling Sample preservation liquid in stored vial 41 can utilize and preserve liquid storage fecal specimens, avoid excrement in time
Bacterium in the volatilization of sample smell or sample from the transformation of the aerobic environment in internal oxygen-free environment to air because make
Change at quantity and then influences measurement result.
The operating principle of the present embodiment is as follows：
When needing to sample excrement, first by two end station of sampler bag in the both sides of toilet seat.
Then excrement collector is opened, it is spare is placed on side.The state of excrement collector is as depicted in figs. 1 and 2 at this time.
After an action of the bowels, with sampling head 30 dejecta sampling device bundle take excrement, when sample reach sampling head 30 on graduation mark when, stop after
It is continuous to advance.Due to the blind end 31 of sampling head 30 outer surface edge by the direction of the second content neck as blocking portion
The end face blocking of one inside diameter 11, so, push shell 10, you can complete to prick extract operation.
Sampler is extracted out from sample.Due to having the first frictional damping between sampling head 30 and the first inside diameter 11, adopt
The frictional force that sample device can be generated during extracting out between sample and sampling head 30 is less than the size of the first frictional damping, institute
It can be remained stationary as in the first inside diameter 11 during sampler is extracted out with sampling head 30.
Stored vial 41 is taken out, sampling head 30 is extend into stored vial 41, due to the storage bottleneck of stored vial 41
42 internal diameter is more than the outer diameter of sampling head 30, so during sampling head 30 is sent to stored vial 41, it will not be with storage
Bottleneck 42 is touched.After sampling head 30 is sent to stored vial 41, the forced section 21 for moving back bar 20 is pushed, bar 20 is moved back and passes through
Force section 22 pushes the blind end 31 of sampling head 30 to drop into storage bottle so that sampling head 30 leaves the first inside diameter 11
In body 41.Fig. 3 illustrates the sectional structure of dejecta sampling device in pushing course.
Storage bottle cap is tightened with stored vial 41, is slightly shaken so that the preservation liquid and sample in stored vial 41 are mixed
It closes.
Storage bottle is encased in packing box, detection is returned.
Embodiment three
As shown in fig. 6, the present embodiment and embodiment one the difference is that, move back between a part for bar 20 and shell 10
For being slidably matched with the second frictional damping, moving back bar 20 can overcome the second frictional damping to exist when forced section 21 is by thrust
To harness motion in shell 10.Specifically, in embodiment one, it is to be inserted into shell from the larger side of the opening of shell 10 to move back bar 20
In body 10.In fact, in the present embodiment, it is provided with an annular inner convex platform in the housing 10, annular inner convex platform is limited and taken
The blocking portion of the move distance of sample head 30, the diameter for moving back the force section 22 of bar 20 are less than the diameter at the middle part for moving back bar 20, move back bar 20
Force section 22 can be passed through from annular inner convex platform, the inner wall of shell 10 and move back bar 20 middle part formed frictional damping.Move back bar
20 enter from the other side of shell 10.
Using being slidably matched with the second frictional damping is formed between the part and shell 10 for moving back bar 20, can prevent
Bar 20 is moved back at will to move, to sampling head 30 cause impact and so that sampling head 30 falls off.It is taken in this way, finally improving
The position holding capacity of sample head 30 in the housing 10.
