Embodiment

Below in conjunction with concrete accompanying drawing, the utility model is described in detail.

Feces examination detection kit 10 as shown in Fig. 1 to 12, comprise integrated sample collecting and detecting device, sampling rod 4 and the reagent bottle 7 of buffer solution is housed, described integrated sample collection and pick-up unit comprise sample reception chamber 1, pattern detection chamber 2 and setting-out valve 3, and setting-out valve is positioned between collection well and pattern detection chamber.Sample proportioning device 5 and sample outlet hole 11 is comprised in sample reception chamber 1.The lower end of setting-out valve 3 comprises setting-out hole 31, pattern detection chamber 2 comprises sample holes 21.When setting-out valve is positioned at primary importance, the liquid that setting-out valve has intercepted sample outlet hole and sample holes communicates.When setting-out valve is positioned at the second place, setting-out hole is between sample outlet hole and sample holes, and now sample outlet hole, setting-out hole and sample holes liquid communicate.In a preferred scheme, setting-out valve 3 is arranged in setting-out valve chamber 33.

Adopting in the specific embodiment promoting the setting-out of setting-out valve, before detection sample, setting-out valve 3 is positioned at primary importance as shown in Figures 4 and 5, and the baffle plate 32 of setting-out valve, between sample outlet hole 11 and sample holes 21, has intercepted the fluid path between sample outlet hole and sample holes.When needs detect sample, promote setting-out valve 3 to use downwards to the second place as shown in Figures 6 and 7, the setting-out hole 32 of setting-out valve is between sample outlet hole and sample holes, make to form liquid between sample outlet hole and sample holes to communicate, detection sample enters in pattern detection chamber through sample outlet hole, setting-out hole and sample holes and completes detection.

Pull in the specific embodiment of setting-out valve setting-out in employing, before detection sample, setting-out valve 3 is positioned at primary importance as shown in Figure 8, and the baffle plate 32 of setting-out valve, between sample outlet hole 11 and sample holes 21, has intercepted the fluid path between sample outlet hole and sample holes.When needs detect sample, setting-out valve 3 is pulled upwards to use, setting-out valve 3 is made to be positioned at the second place as shown in Figure 9, the setting-out hole 32 of setting-out valve is between sample outlet hole and sample holes, make to form liquid between sample outlet hole and sample holes to communicate, detection sample enters in pattern detection chamber through sample outlet hole, setting-out hole and sample holes and completes detection.After pulling the setting-out of setting-out valve, setting-out valve can be pulled out pick-up unit by operator completely, also upwards can carry with hand always and hold setting-out valve and communicate to keep the liquid between sample reception chamber and pattern detection chamber.In a preferred version as shown in Figure 9, after setting-out valve is pulled, setting-out valve is by kink 34 bending along setting-out valve, taken on detection means by the setting-out valve of bending, setting-out valve is because barrier effect, after letting go, setting-out valve also can not fall again, thus ensures that between sample outlet hole and sample holes, liquid communicates.Operator can also select additive method to keep liquid to communicate.

Before setting-out, sample outlet hole and sample holes can be sealed further by seal.In the embodiment such as shown in Fig. 4 to 7, described seal is O-ring seal 35.Described O-ring seal is arranged on the sample outlet hole place in the face of this side of setting-out valve guard and the setting-out hole place in the face of this side of setting-out valve guard respectively, and between baffle plate with O-ring seal, liquid sealing coordinates.When setting-out valve is positioned at primary importance, sample liquid can not from baffle plate and and sample outlet hole between gap flow out.When setting-out valve is positioned at the second place, described O-ring seal can prevent liquid from flowing out from the upper open end of setting-out cavity further.

Described seal can also be diaphragm seal.In sample outlet hole and sample holes, all sticky note has diaphragm seal, and described diaphragm seal and the adhesion of setting-out valve phase.Promote or pull in the process of setting-out valve, diaphragm seal is torn by setting-out valve along with the motion of setting-out valve, thus opens the sealing state of sample outlet hole and sample holes.In order to liquid before ensureing setting-out does not communicate, other modes can also be adopted.

In order to avoid the secondary of pick-up unit uses, the upper end of setting-out valve 3 also comprises web member 37 as shown in FIG. 10 and 11, and web member is that easy fracture material is made.Before use, web member 37 is connected with the madial wall of setting-out valve chamber 33 as shown in Figure 10.When needs setting-out inspection, when mobile setting-out valve process, web member 37 ruptures, as shown in figure 11.Web member 37 ruptures, and shows that this sample collection and pick-up unit are previously used, cannot reuse.

Comprise sample proportioning device 5 in sample reception chamber 1, described sample proportioning device comprises a dosing hole 51, the sectional dimension of dosing hole and the barred body 41 of sampling rod roughly the same.When inserting dosing hole with the sampling rod 4 of sample, the edge of this dosing hole and the sidewall close contact of acquisition rod, thus scrape and wipe sample unnecessary on sampling rod, guarantee to collect the sample to be checked of fixed amount.After the barred body of sampling rod inserts dosing hole, its incidental sample mixes with the damping fluid in sample reception chamber, and solid sample is quantitatively diluted.In a preferred version, the portion of being affectedly bashful of sampling rod 42 and the upper shed close contact of collection well, keep the liquid sealing state in collection well, the damping fluid in collection well can not exhaust chamber external.

At least comprise a test paper 22 in pattern detection chamber 2, after sample enters test chamber, contact with test paper, finally obtain testing result.In a preferred version, in pattern detection chamber, also comprise a sample pool 23.After sample is introduced into sample pool, more slowly tested test paper absorbs, and sample pool plays the effect of a buffering.After opening setting-out valve, the great amount of samples entered fast can not impact test paper immediately.In a specific embodiment, test paper comprises the test paper of FOB test paper and helicobacter pylori, described test paper is latex or the lateral flow Test paper of gold mark mark.

Carrying out, in the specific embodiment detected, first gathering ight soil with sampling rod, and the sampling rod with ight soil is being inserted in collection well 1 by the dosing hole 51 of sample proportioning device.Dosing hole strikes off unnecessary fecal sample, and the sample on sampling body mixes with the buffer solution in collection well.During detection, testing staff is by pulling or promoting setting-out valve 3, and arrived in test chamber 2 by final after sample outlet hole, setting-out hole and sample holes by the sample diluted, the tested test paper 22 of sample is caught, and detects and terminates rear sentence read result.Whole testing process sample can not expose in atmosphere, and when to detect be can manual control.Testing staff can after single sample collection start detection immediately, after multiple sample collection also can be waited complete, start simultaneously.Sample collection described in the utility model and pick-up unit can be pulled by instrument or promote setting-out valve, thus realize Aulomatizeted Detect.
