Description
Technical field
The present invention relates to a kind of experiment equipment, the quantitative fan-shaped count table surface sample culture dish of especially a kind of extrusion type.
Background technique
Culture dish is one of most widely used experiment equipment in biology, is usually used in the objects such as packaging material for food, tableware
The culture of body surface microorganism is tested, and the sampling of body surface microorganism usually wipes determinand body surface with sterile cotton swab
Cotton swab or filter paper are perhaps transferred in buffer with aseptic filter paper abutting object under test surface later and are eluted, to reach by face
To the purpose of sampling.But cotton swab or filter paper can not discharge microorganism collected completely, be easy to cause Bacterial diversity
Incomplete culture；In addition the sampling of body surface microorganism needs sterile working, and cotton swab or filter paper are carrying out microorganism
Acquisition and elution during, be easy pollution by environmental microorganism, be extremely difficult to the requirement of sterile working；These disadvantages
It will cause the deviation of body surface microorganism testing result.In addition, the operating process of the above method is cumbersome, inefficiency, hold
Easily cause the waste of human resources.When the culture dish pours into agar medium, the volume of pouring into of culture medium is usually operator
Depending on empirically, therefore the agar medium of different personnel pours into volume and may have larger difference, to influence relevant experiment
As a result.When the colony counts for the target culture that the culture medium in culture dish is grown are huge, the counting process of bacterium colony then compares
It is cumbersome.

For logical technical staff, without creative efforts, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structural schematic diagram of the quantitative fan-shaped count table surface sample culture dish of extrusion type；Fig. 2 is provided at the bottom wall
The schematic diagram of radioactive ray；In figure：
1 is ware lid, and 2 be ware bottom, and 3 be tegmental wall, and 4 be bottom wall, and 5 be ware lid side wall, and 7 be the first ware downside wall, and 71 be movable ware bottom
Side wall, 72 be the first buckle, and 73 be the second buckle, and 22 be graduation mark, and 23 be radioactive ray.
Specific embodiment
It is right below in conjunction with the drawings and specific embodiments in order to be more clear the objectives, technical solutions, and advantages of the present invention
The present invention is described in further detail.It should be appreciated that described embodiment is only used to explain the present invention, it is all to be based on
Simplified or equivalent variations, all belongs to the scope of protection of the present invention made by technical solution of the present invention.
In the discussion of specific embodiment, the shape of the quantitative fan-shaped count table surface sample culture dish of the extrusion type is preferable
Select it is round, still, those skilled in the art should be understood that it is suitable for such as ellipse, rectangle or its
It is suitable for the shape of culture dish.
The invention discloses a kind of quantitative fan-shaped count table surface sample culture dishes of extrusion type, including ware bottom 2 and relaxation covering
In the ware lid 1 on ware bottom 2, the ware lid 1 includes tegmental wall 3 and at least one surround the ware lid side wall 5 holded up, institute from tegmental wall 3
The ware bottom 2 stated includes bottom wall 4 and at least one surround the first ware downside wall 7 and at least one parallel sleeve holded up from bottom wall 4
Movable ware downside wall 71 in 7 outside of the first ware downside wall；The diameter of the ware lid side wall 5 is greater than the movable ware bottom side
Wall 71；The bottom wall 4 is identical as the shape of the tegmental wall 3.The first ware downside wall 7 is equipped at least one the second buckle of circle
73, second buckle 73 was around described first ware downside wall 7 one weeks, the circle plane of second buckle 73 and the bottom wall
4 plane is parallel；The movable ware downside wall 71 is equipped at least one the first buckle 72 of circle, and first buckle 72 is around described
The circle plane of movable ware downside wall 71 1 weeks, first buckle 72 is parallel with the plane of the bottom wall 4；First card
Button 72 and second buckle 73 can be closely fitted into, to maintain to be in institute without activity ware downside wall 71 described under external force
State the technical characteristic of 7 top of the first ware downside wall；When the direction along certainly movable 71 to the first ware downside wall 7 of ware downside wall, apply
When adding active force to the movable ware downside wall 71, the embedded structure of first buckle 72 and second buckle 73 can pine
It opens, movable ware downside wall 71 can be moved in parallel along the direction of the first ware downside wall 7 at this time.Features described above has determined the extrusion
The basic structure of the quantitative fan-shaped count table surface sample culture dish of formula, wherein the first ware downside wall 7, movable ware downside wall 71 and bottom wall
4 spaces formed are solidified when cultivating inner cavity by the enough agar mediums of injection to the culture medium as culture inner cavity
Afterwards, the movable ware downside wall 71 is applied force to, keeps movable ware downside wall 71 parallel along the direction of the first ware downside wall 7
It is mobile, until the plane of movable ware downside wall 71 is lower than the plane of the agar medium, by the agar culture when use
Base plane is directly covered in object under test surface, that is, can reach the purpose of sampling microorganisms from surface of object, avoid using cotton swab
Son or filter paper carry out the tedious steps eluted again after microorganism acquisition, greatly simplify the mistake of sampling microorganisms from surface of object
Journey, and overcome and be easy the problem of being polluted by environmental microorganism in sampling process, at the same improve test result accuracy and
Working efficiency.
In the embodiment of the quantitative fan-shaped count table surface sample culture dish of the extrusion type, the diameter of the bottom wall 4 is greater than
The diameter of the tegmental wall 3, the setting of this feature can be limited when ware lid 1 and the fastening of ware bottom 2, and ware lid side wall 5 can only be supported in
Bottom wall 4.In addition, the height of the activity ware downside wall 71 and the sum of the height of the first ware downside wall 7, are less than the ware lid
The height of side wall 5, this feature can limit when ware lid 1 and the fastening of ware bottom 2 that there are one between activity ware downside wall 71 and tegmental wall 3
Fixed gap prevents the agar medium from contacting with tegmental wall 3.
The first ware downside wall 7 is additionally provided at least one graduation mark 22, and the graduation mark 22 is around the first ware bottom
Side wall 7 one weeks, the circular flat of the graduation mark 22 was parallel with the plane of the bottom wall 4；The graduation mark 22 can indicate
Agar medium pours into volume, to avoid pouring into the difference of volume because of personal experience's difference bring.
In the bottom wall 4, the radioactive ray 23 at 4 edge of bottom wall are extended to from 4 central point of bottom wall equipped at least two, it is described
Radioactive ray 23 bottom wall 4 is divided into the fan-shaped regions of at least two area equations；When the culture medium institute in culture dish
When the colony counts of the target culture of growth are huge, the bacterium colony count results in a fan-shaped region can be used, multiplied by corresponding
Multiple（In embodiment shown in Fig. 2, bottom wall 4 is equally divided into the fan-shaped region of 8 area equations, so multiple is 8）With
It indicates all clump counts of culture dish, therefore simplifies the counting process of bacterium colony.
Above by description of listed embodiment, the basic ideas and basic principles of the present invention are elaborated.Obviously, institute
The embodiment of description is only a part of the embodiments of the present invention, and non-limiting exhaustion.Based on the embodiments of the present invention, originally
Field those of ordinary skill all other embodiment obtained under the premise of not making the creative labor, belongs to this hair
Bright protection scope.
