Abstract
The utility model discloses a kind of orifice plate for biofilm experiments, comprise base plate, described base plate offers the bottom plate hole for holding microorganism, what described base plate is positioned at bottom plate hole is outside equipped with outer support, described outer support has the height extended along bottom plate hole depth direction, and described bottom plate hole extends to the top of outer support, the top of described base plate is also provided with upper cover plate, described upper cover plate is provided with open cavity, the bottom of described open cavity is provided with the communicating aperture entered for sample loading gun, the aperture of described communicating aperture diminishes from along near open cavity side gradually to the side keeping away oral cavity, described communicating aperture communicates with bottom plate hole.Orifice plate of the present utility model is in experimentation, and because the existence of open cavity and communicating aperture makes sample loading gun hold the edge and the bottom disrupting biofilm that not easily touch well, upper cover plate is connected comparatively firm with base plate simultaneously, not easily topples over.
Description
Technical field
The utility model relates to a kind of laboratory apparatus, particularly relates to a kind of orifice plate for biofilm experiments.
Background technology
Bacterial biof iotalm (bacterialbiofilm, BF) being bacterium is adsorbed in inertia or surface of active material formation in process of growth a kind of corresponding with planktonic cells growth pattern for adapting to living environment, being made up of the extracellular matrix of bacterium and self secretion.This kind of bacterial population resistance is extremely strong, can escape host immune effect, and infection site is difficult to thorough removing, is one of major reason of Difficult infection clinically.
Bacterial biof iotalm, as relatively emerging research field, there is no how much by the standard method extensively approved.The artificial generating unit of current existing bacterial biof iotalm mainly contains test tube method, Microdilution plate method, put sheet method, dull and stereotyped Diaphragm Method, pipeline method, stream room method, revolve dish method, but all there is the defective of self in these class methods, such as: test tube method, put sheet method and be not suitable for batch detection, although Microdilution plate method has the advantage of batch processing, especially the operating speed accelerating gross sample can also keep testing simultaneously conforming in, but in actually operating, also there is following limitation in this way: during this method of use for laboratory cleaning at present, sample loading gun easily touches edge and the bottom disrupting biofilm of well, affect experimental result.There is limitation in dull and stereotyped Diaphragm Method research mode.Pipeline method, stream room method, to revolve dish method higher to equipment requirements, can not common lab and on a large scale in use.
Utility model content
The purpose of this utility model is to solve technical problem involved in background technology, providing a kind of orifice plate for biofilm experiments.
The technical solution of the utility model is: a kind of orifice plate for biofilm experiments, comprise base plate, described base plate offers the bottom plate hole for holding microorganism, what described base plate is positioned at bottom plate hole is outside equipped with outer support, described outer support has the height extended along bottom plate hole depth direction, and described bottom plate hole extends to the top of outer support, the top of described base plate is also provided with upper cover plate, described upper cover plate is provided with open cavity, the bottom of described open cavity is provided with the communicating aperture entered for sample loading gun, the aperture of described communicating aperture diminishes from along near open cavity side gradually to the side keeping away oral cavity, described communicating aperture communicates with bottom plate hole.
Preferably, described upper cover plate is provided with side direction erecting frame, described side direction erecting frame is provided with the lateral connection arm be connected with upper cover plate, described lateral connection arm connects longitudinal connecting arm away from one end of upper cover plate, the side of described lateral connection arm and longitudinal connecting arm forms side direction mounting groove, and described side direction mounting groove and outer support are interlocked.
Preferably, the cross-sectional shape of described open cavity is trapezoidal.
Preferably, upper cover plate is also provided with the otic placode being convenient to grip.
Preferably, described base plate is made up of polyacrylamide.
In sum, the utility model has following advantage:
Orifice plate of the present utility model is in experimentation, and because the existence of open cavity and communicating aperture makes sample loading gun hold the edge and the bottom disrupting biofilm that not easily touch well, upper cover plate is connected comparatively firm with base plate simultaneously, not easily topples over.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model.
Embodiment
As shown in Figure 1, a kind of orifice plate for biofilm experiments, comprise base plate 1, described base plate 1 offers the bottom plate hole 2 for holding microorganism, what described base plate 1 is positioned at bottom plate hole 2 is outside equipped with outer support 3, described outer support 3 has the height extended along bottom plate hole 2 depth direction, and described bottom plate hole 2 extends to the top of outer support 3, the top of described base plate 1 is also provided with upper cover plate 4, described upper cover plate 4 is provided with open cavity 41, the bottom of described open cavity 41 is provided with the communicating aperture 42 entered for sample loading gun 5, the aperture of described communicating aperture 42 diminishes from along near open cavity 41 side gradually to the side keeping away oral cavity 41, described communicating aperture 42 communicates with bottom plate hole 2.
Described upper cover plate 4 is provided with side direction erecting frame 43, described side direction erecting frame 43 is provided with the lateral connection arm 431 be connected with upper cover plate 4, described lateral connection arm 431 connects longitudinal connecting arm 432 away from one end of upper cover plate 4, described lateral connection arm 431 forms side direction mounting groove 433 with the side of longitudinal connecting arm 432, and described side direction mounting groove 433 is interlocked with outer support 3.
The cross-sectional shape of described open cavity 41 is trapezoidal.Upper cover plate 4 is also provided with the otic placode 44 being convenient to grip.Described base plate 1 is made up of polyacrylamide.
In use, sample loading gun 5 aims at communicating aperture 42 position from open cavity 41 side enters, and inserts in communicating aperture 42 at any time, due to the change in communicating aperture 42 aperture, after making sample loading gun 5 go deep into certain position, cannot continue deeply, to avoid and contact with the direct of bottom plate hole 2.
More than illustrate it is only to explanation of the present utility model, those of ordinary skill in the art's can completely is made to implement this programme, but be not to restriction of the present utility model, those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification sheets, and these are all not creative amendments.As long as but be all subject to the protection of patent law in right of the present utility model.
