A kind of just sample collector
The utility model relates to feces collection fields, and in particular, to a kind of just sample collector.
Stool examination is one of routine clinical laboratory examination project, can relatively intuitively understand gastrointestinal tract one by this inspection
A little pathological phenomenons, judge indirectly alimentary canal, pancreas, liver and gallbladder function status, be divided under naked eyes general character observation, mirror and checking
And chemical examination.
Current excrement collector mostly uses test tube cooperation hairbrush practical, acquires just sample by hairbrush and hairbrush is put in examination
In dilution in pipe, in this method collection process or people is allowed to generate uncomfortable nausea, and the just amount acquired is less, and other
The problems such as collector acquired by spherical shell, inconvenient, emission of bad smell that there is also transports and using trouble, it is therefore necessary to design one
The novel just sample collector of kind.

Spring 5 and two hemispherical shells scratch pawl 6, and the inner coaxial of pipe lid 2 is provided with a hollow pipe 7, the top of hollow pipe 7 and Guan Gai
2 top connections, the bottom end of hollow pipe 7 extend to the inside of transparent dilution tube 1, and the setting that push-pull rod 3 can move is in hollow pipe 7
Interior and push-pull rod 3 upper end extends to the top of pipe lid 2, and spring 5 is set in the upper end of push-pull rod 3 and is being pushed away by setting
It is contradicted at the top of the end cap 8 on 3 top of pull rod and pipe lid 2, push-pull rod 3 is equipped with the top screw thread with hollow pipe 7 by one end of proximal cover 8
The interconnecting piece 9 of connection, connector 4 are flexibly connected with the lower end of push-pull rod 3, and two hemispherical shells stingy fitting of pawl 6 formation one is complete
Whole sphere and be located at below the bottom end of hollow pipe 7, the top that two hemispherical shells scratch pawl 6 pass through bar shaped bar 10 with connect
First 4 bottom is hinged, and there are two curved rods 11 for symmetrical hinged setting on the lower end outer wall of hollow pipe 7, and curved rod 11 is far from hollow
The outer wall that pawl 6 is scratched with corresponding hemispherical shell in one end of pipe 7 is hinged.
An annular flange 12 is provided at the bottom end outer rim of push-pull rod 3, connector 4 is cylindrical structure and its top is set
One is equipped with for accommodating the pockets 13 of annular flange 12, what annular flange 12 rotated is contained in pockets 13, holds
Receive groove 13 top opening diameter be less than annular flange 12 outer diameter.Annular flange 12 and the cooperation of pockets 13 ensure that
Push-pull rod 3 will not be such that the connector 4 of lower section also and then rotates in rotation.
There are two the upper hinged seat 14 hinged for 10 upper end of bar shaped bar, each hemispherical shell is scratched for the bottom setting of connector 4
The top of pawl 6 is provided with the lower hinged seat 15 hinged for 10 lower end of bar shaped bar.The decline of connector 4 drives under two bar shaped bars 10
Drop, the decline of bar shaped bar 10 drive the stingy pawl 6 of two hemispherical shells that lower end is hinged therewith to decline, and two hemispherical shells are scratched at the same time
Pawl 6 is rotated around lower hinged seat 15, to be flared out preparation for acquiring just sample.
First hinged seat hinged there are two the upper end for curved rod 11 is symmetrical arranged in the lower end outer cylindrical wall of hollow pipe 7
16, each hemispherical shell, which is scratched at the lateral arcs top of pawl 6, is equipped with second hinged seat 17 hinged for 11 lower end of curved rod, curved rod 11
Cancave cambered surface towards hemispherical shell scratch pawl 6 be arranged.During two hemispherical shells are scratched pawl 6 and opened, curved rod 11 is by hemisphere
Shelly-shaped stingy pawl 6 is held, and ensure that hemispherical shell is scratched during pawl 6 declines can smoothly open.
Interconnecting piece 9 is the cylindrical structure that diameter is greater than 3 diameter of push-pull rod, and the diameter of interconnecting piece 9 is equal to the interior of hollow pipe 7
Diameter, the lower end of interconnecting piece 9 are bevel structure, and interconnecting piece 9 is equipped with external screw thread 18, the top inner wall of hollow pipe 7 by 8 one end of proximal cover
Equipped with the internal screw thread 19 being tightly connected for interconnecting piece 9, the length of external screw thread 18 is greater than length when spring 5 compresses.It has acquired just
After sample, interconnecting piece 9 is connect with pipe lid 2 by thread seal, two hemispherical shells are scratched pawl 6 and opened at this time, make the just sample of acquisition
It is sufficiently diluted in transparent dilution tube 1.
Spring 5 is set in the outside of interconnecting piece 9, the upper and lower side of spring 5 top with the bottom of end cap 8 and pipe lid 2 respectively
It contradicts.Decline push-pull rod 3 is pressed when acquiring just sample, then opened two hemispherical shells are scratched pawl 6 and are inserted into just sample, then are released
Push-pull rod 3 is put, under the elastic force effect of spring 5, two hemispherical shells scratch 6 Quick-clamped of pawl closure, complete sampling.
Pipe lid 2 is connected with the bottle mouth position of transparent dilution tube 1 by thread seal.Transparent dilution tube 1 is provided with dilution, uses
In the collected just sample of dilution.
Working principle: first separating pipe lid 2 with transparent dilution tube 1 when use, then declines push-pull rod 3 by lower cover 8,
And then so that two hemispherical shells is scratched pawl 6 and open and be inserted into just sample, then discharge push-pull rod 3, under the elastic force effect of spring 5, two
A hemispherical shell scratches 6 Quick-clamped of pawl closure, completes sampling, pipe lid 2 is tightened on transparent dilution tube 1 again after the completion of sampling
On, and so that two hemispherical shells is scratched pawl 6 by lower push-pull bar 3 and open, be diluted in the just sample of acquisition sufficiently in transparent dilution tube 1,
Last rotating sliding bar 3 makes interconnecting piece 9 and pipe lid 2 complete to be tightly connected, and ensure that two hemispherical shells scratch pawl 6 in transparent dilution
Be constantly in open configuration in pipe 1, thus make just sample be sufficiently diluted in dilution, be readily transported simultaneously.
