Embodiment
As depicted in figs. 1 and 2, the quantitative sample treatment pipe that the present embodiment provides comprises body 1, first pipe cap 2, lid 3, sampling rod 4, quantity tube 7 and the second pipe cap 8.Body 1 for holding dilution, first detachable one end being connected to body 1 of pipe cap 2, and the first pipe cap 2 has the apopore 21 be connected with body 1 inside.Lid 3 is connected with the first pipe cap 2 is detachable and covers the apopore 21 on the first pipe cap 2.The other end of the detachable connection pipe body 1 of the second pipe cap 8.
In the present embodiment, be all be connected with externally threaded coupling by internal thread between lid 3 and the first pipe cap 2, between the first pipe cap 2 and body 1 and between the second pipe cap 8 and body 1.Namely dismounting between lid 3 and the first pipe cap 2 or connection can be realized by cap 3.Same, only need rotate the first pipe cap 2 and can realize dismounting between the first pipe cap 2 and body 1 or connection; Rotate the second pipe cap 8 and can realize dismounting between the second pipe cap 8 and body 1 or connection.But the utility model is not limited in any way this.
In the present embodiment, sampling rod 4 is connected with the inside of the second pipe cap 8.Quantity tube 7 is connected to the other end of body 1 and the inside to body 1 is stretched into.In the present embodiment, quantity tube 7 is funnel-form (as shown in Figure 4 and Figure 5), comprises bucket portion 71 and bottle neck 72, and bucket portion 71 has outward extending edge 711, and this edge 711 is one-body molded with the other end of body 1.And bottle neck 72 to stretch into body 1 inner, and on the diameter of the end of bottle neck 72 and sampling rod 4, the maximum gauge of screw thread sample region 41 matches.So-called coupling is: the diameter of the end of bottle neck 72 slightly larger than the maximum gauge of screw thread sample region 41, as bigger 1 millimeter ~ 2 millimeters.But the utility model is not limited in any way this.
Because clinical detection sample mostly is the excreta of human body, as fecal sample.Usually a lot of particles and impurity can be contained in fecal sample.When pattern detection, these particles and impurity can badly influence the result of detection.For effectively removing the particle and impurity that are dissolved with in the dilution of sample to be tested, quantitative sample treatment pipe also comprises at least one deck filtering membrane 5.This at least one deck filtering membrane 5 to be arranged in the first pipe cap 2 and to be positioned at the side of apopore 21 near body 1, the dilution being dissolved with sample to be tested flows out from apopore 21 after filtering through at least one deck filtering membrane 5.
In the present embodiment, in the first pipe cap 2, be provided with one deck filtering membrane 5.But the quantity of the utility model to filtering membrane 5 is not limited in any way.In other embodiment, the quantity of filtering membrane 5 can be two-layer more than.And when more than the quantity of filtering membrane 5 is two-layer, preferably, be arranged at the outflow direction of the dilution being dissolved with sample to be tested, the aperture of filtering membrane 5 diminishes gradually.This setting not only effectively can stop the escape being dissolved with fine particle in the dilution of sample to be tested and impurity, and bed filtration film 5 has better supporting role simultaneously.
The concrete using method of this quantitative sample treatment pipe is: user takes off from body 1 the second pipe cap 8 being connected with sampling rod 4.Screw thread sample region 41 picking sample to be tested on sampling rod 4.The sampling rod 4 being stained with sample to be tested inserted quantity tube 7 and go deep into the inside to body 1.Because the diameter of the end of bottle neck 72 on quantity tube 7 is slightly larger than the maximum gauge of screw thread sample region 41, this will make during insertion, sample unnecessary on screw thread sample region 41 can be delayed at the inside of body 1, from the sampling rod 4 that quantity tube 7 passes, only leave the sample to be tested of 15 milligrams ~ 20 milligrams at screw thread sample region 41 internal memory, realize the quantitative acquisition of sample to be tested.
Then, tighten the second pipe cap 8, rock body 1, the sample to be tested retained in screw thread sample region 41 is dissolved in dilution.Uncap 3, flow to the dilution being dissolved with sample to be tested detecting position from apopore 21 after filter membrane 5 filters.
In the present embodiment, because screw thread sample region 41 is shape of threads, for having better quantitative accuracy, the inwall arranging bottle neck 72 has the burr 721 matched with screw thread sample region 41.
In the present embodiment, for preventing the smell of sample to be tested in body 1 from spreading, also preventing dilution from the junction seepage of filtering membrane 5 and the first pipe cap 2 simultaneously, the packing ring 6 sealed is set near the side of body 1 at filtering membrane 5.In the present embodiment, packing ring 6 is silica gel ring.But the utility model is not limited in any way this.
In the present embodiment, for convenience of dismounting or connect the first pipe cap 2 and the second pipe cap 8, the lateral wall that the first pipe cap 2 and the second pipe cap 8 be set has anti-slip veins.In the present embodiment, described anti-slip veins is many fins extended along the first pipe cap 2 or the second pipe cap 8 length direction.
In sum, the quantitative sample present treatment pipe that the utility model provides has following beneficial effect:
Adopt the sampling rod 4 with screw thread sample region 41 to obtain sample to be tested, the sampling rod 4 obtained after sample stretches in body 1 from the other end of body 1 through quantity tube 7, sample to be tested is dissolved in the dilution in body 1.Because in the end diameter of quantity tube 7 and sampling rod 4, the maximum gauge of screw thread sample region 41 matches, this is arranged so that when sampling rod 4 stretches into body 1 by quantity tube 7, sample detention unnecessary on sampling rod 4 is on quantity tube 7, in screw thread sample region 41, only retain the sample of fixed amount, realize quantitative sampling.
In addition, arrange quantitative sample treatment pipe and also comprise at least one deck filtering membrane 5, the dilution being dissolved with sample to be tested detects after at least one deck filtering membrane 5 filters removal particle and impurity after the apopore 21 the first pipe cap 2 flows out.The quantitative sample treatment pipe that the utility model provides adopts filtering membrane 5 to remove particle in sample to be tested and impurity, avoids particle and impurity to the interference of testing result, greatly improves accuracy of detection.Inner by dilution being placed on body 1, and on body 1, be provided with the first pipe cap 2 of packing ring 6, effectively prevent leakage and peculiar smell diffusion.
Although the utility model discloses as above by preferred embodiment; but and be not used to limit the utility model; anyly know this those skilled in the art; not departing from spirit and scope of the present utility model; can do a little change and retouching, therefore protection domain of the present utility model is when being as the criterion depending on claims scope required for protection.
