Description
Technical field
The utility model relates to inspection and quarantine technical field, especially a kind of microbial contamination sample collecting device.
Background technique
Plate is very important in the inspection of inspection and quarantine field, microorganism.The first step of Micro biological Tests work is just
It is acquisition microbial contamination sample, the mode of collecting sample is varied, and the mode of fairly simple and common collecting sample is
It is infected with microbial contamination sample using aseptic cotton carrier, then the cotton swab for collecting sample is put into the culture vessels such as test tube
It fractures, leaves cotton swab head in culture vessel.
However, due to fracture cotton swab when, cotton swab head must not be polluted again, therefore the movement for the cotton swab that fractures can only train
The inner wall strength for supporting dependence culture vessel in container fractures, inconvenient, and damage culture vessel is possible in operating process.
Utility model content
For the problems of above prior art, the purpose of the utility model is to provide a kind of microbial contamination samples
Acquisition device, it is simple and reasonable, it is easy to operate without the movement for the cotton swab that fractures, culture vessel will not be damaged.
To achieve the goals above, the technical solution of the utility model is:
A kind of microbial contamination sample collecting device comprising have: lever comprising have for interting the hollow of cotton swab bar
Through-hole；One end of the lever offers arc notch；The radian of the arc notch is not less than 180 °；The lever it is close
The end face of that one end of the arc notch is connected with elastic ring；The internal diameter of the elastic ring is less than the diameter of the cotton swab bar；
Poker, one end are actively threaded through in the hollow via-hole, and the other end stretches out the separate arc notch of the lever
That one end.
As a kind of specific embodiment, the hollow via-hole includes internal screw thread；The poker include with it is described interior
The external screw thread that screw thread matches.
As a kind of specific embodiment, that one end far from the arc notch of the poker is connected with end.
Further, the end is cylindrical.
Further, the end includes along its circumferentially spaced several non-slip groove.
Further, the diameter of the end is 0.8cm~2.0cm.
As a kind of specific embodiment, the width of the arc notch is not less than the diameter of cotton swab bar.
As a kind of specific embodiment, the radian of the arc notch is at 180 °~270 °.
A kind of microbial contamination sample collecting device of the utility model has following Advantageous effect compared with the prior art
Fruit:
Cotton swab bar sequentially passes through the elastic ring and the hollow via-hole, after acquiring sample with cotton swab head, Ji Keli
Cotton swab bar is truncated at the arc notch with cutter, in order to which cotton swab bar, the arc of the arc notch is fully truncated
Degree is not less than 180 °.It is truncated after cotton swab bar, since the internal diameter of the elastic ring is less than the diameter of the cotton swab bar, the elasticity
Ring will have that section of cotton swab fixed clamp of cotton swab head.The poker is pushed at this time, can will have the part of cotton swab head
Cotton swab is pushed into culture vessel.This process is not necessarily to the cotton swab bar that fractures in culture vessel, easy to operate feasible, will not damage culture
Container.
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.
Detailed description of the invention

Specific embodiment
Referring to Fig. 1, a kind of microbial contamination sample collecting device comprising have: lever 1 comprising have for interting
The hollow via-hole of cotton swab bar 410；One end of the lever 1 offers arc notch 110；The radian of the arc notch 110 is not
Less than 180 °；The end face of that one end close to the arc notch 110 of the lever 1 is connected with elastic ring 2；The elastic ring
2 internal diameter is less than the diameter of the cotton swab bar 410；Poker 3, one end are actively threaded through in the hollow via-hole, the other end
Stretch out that one end far from the arc notch 110 of the lever 1.
Cotton swab bar 410 sequentially passes through the elastic ring 2 and the hollow via-hole, after acquiring sample with cotton swab head 420,
Cotton swab bar 410 is truncated at the arc notch 110 using cutter, in order to which cotton swab bar 410, institute is fully truncated
The radian of arc notch 110 is stated not less than 180 °.It is truncated after cotton swab bar 410, described in the internal diameter of the elastic ring 2 is less than
The diameter of cotton swab bar 410, the elastic ring 2 will have 4 fixed clamp of that section of cotton swab of cotton swab head 420.Described in pushing at this time
Part cotton swab 4 with cotton swab head 420 can be pushed into culture vessel by poker 3.This process in culture vessel without rolling over
Disconnected cotton swab bar 410, it is easy to operate feasible, culture vessel will not be damaged.
It is smooth accurate when wherein, in order to guarantee to push cotton swab using the poker 3, it should be ensured that the poker 3 is described
Propulsion in hollow via-hole is in the consistent linear motion of height, described hollow to lead in the present embodiment using threading action by the way of
Hole inner wall is connected with internal screw thread, and the poker 3 then includes pilum 310 and the external screw thread that is connected on 310 outer wall of pilum
311, when the poker 3 promotes in the hollow via-hole, the mode of threading action is taken, it is smooth accurate, convenient for manipulation.
According to common sense, the diameter very little of cotton swab bar 410, the diameter of the poker 3 substantially with the diameter phase of cotton swab bar 410
When, operating personnel's finger turn poker 3, it is difficult to operate, convenient for poker 3 described in turn, the poker 3 far from described
That one end of arc notch 110 is connected with end 320, it is preferable that the end 320 is cylindrical, certainly, according to finger
Experience, the diameter of the end 320 are 0.8cm~2.0cm, and such diameter range rotates the end 320 convenient for two fingers.
Further, the end 320 further includes having along its circumferentially spaced several non-slip groove 321, and the non-slip groove 321 improves
Frictional force between finger and the end 320 is conducive to end 320 described in operating personnel's turn, and then promotes the poker 3 in institute
State the movement in hollow via-hole.
It is the important job step of a step that cotton swab bar 410, which is truncated, using cutter in the arc notch.In order to fast
Prompt that cotton swab bar 410 is effortlessly truncated, the width and radian of the arc notch should all be suitable.Passing through repetition test and verifying
Basis on, preferably 180 °~270 ° of the radian of the arc notch of the utility model, width H should be not less than cotton swab bar
410 diameter.
The utility model is not limited to above embodiment, if the various changes or deformation to the utility model do not take off
Spirit and scope from the utility model, if these changes and deformation belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also intended to encompass these changes and deformation.
