Description
Technical field
The present invention relates to a kind of micro-fluidic chip clamp experiment porch based on 3D printing, specifically, being 3D printing
Technology is applied in the making of micro-fluidic experiment porch, realizes the rapid processing of experiment porch, reduces cost of manufacture, is easy to operate
Purpose, which is suitable for various biomedical detections and chemical analysis application using micro-fluidic chip, belongs to
In microfluidic art.
Background technology
3D printing belongs to one kind of rapid shaping technique, and central principle is：" Layered manufacturing is successively superimposed ".3D printing
The printed material of machine is raw material of device, such as metal, ceramics, plastics, sand etc..Specific implementation process is to utilize computer aided manufacturing
It helps design or modeling software to commodity modeling, model division is then generated STL standard data files at section successively.3D
Printer successively prints and is bonded, produce entity by identifying file middle section information.At present its be widely used in automobile,
The fields such as aviation, medical treatment, building.Material is greatly saved in the principle of its increasing material manufacturing, reduces product cost, and product quality is steady
It is fixed.But for the very high product of required precision, need subsequently to polish and finish；Because in process, material is heated repeatedly,
Therefore interiors of products stress is complicated, product material performance is poor, such as intensity, rigidity etc..So 3D printing for required precision not
High, product strength requires also not high product highly advantageous.
Microfluidic chip technology is one of the hot spot of present analysis science research.Micro-fluidic chip is biology, chemistry, doctor
The basic operation units such as sample preparation, reaction, separation, the detection of analytic process are learned to be integrated on the chip of one piece of micro-meter scale,
It is automatically performed analysis overall process.Microfluidic chip analysis is using chip as operating platform, while based on analytical chemistry, with microcomputer
EDM Technology is to rely on, and is current main application with life science using microchannel network as structure feature, is current micro-
The emphasis of analysis system field development.And laboratory is needed through connecting tube when carrying out micro-fluidic chip experiment fluid
It imports in micro-fluidic chip, therefore experiment is required for connecting connecting tube in each interface every time, while being sealed.It is each micro-fluidic
Chip has several interfaces, and it is small to make an excuse size, so take over operation can consume the plenty of time in experiment, and quality of connection with
Manual operation stability is related, easily occurs leaking and blocking.The unreasonable arrangement of connecting tube can also influence Germicidal efficacy and result.
Invention content
Micro-fluidic chip connecting tube relies on experimenter's operating experience, time-consuming in order to overcome in existing laboratory work and
The cumbersome problem of connection procedure, the present invention provide a kind of micro-fluidic chip clamp experiment porch based on 3D printing, should be based on 3D
The micro-fluidic chip clamp experiment porch of printing not only assists in experimenter and quickly connects the company for completing disengaging micro-fluidic chip
It takes over, and can guarantee quality of connection, operation is simple.
The technical solution adopted by the present invention to solve the technical problems is：It is of the present invention based on the micro-fluidic of 3D printing
Chip fixture experiment porch, including substrate, cover board, bolt connecting hole, substrate and cover board two parts are experiment porch agent structure,
Two parts are bolted, substrate and cover plate central there are the rectangular window of same size and four bolt holes, four
Rectangular preiection positioning setting, substrate have ramp type micro-fluidic chip insert port, inside to have left and right positioning chuck, the cover board left and right sides
There are six connecting tube insert port and sealing ring installation sites for each distribution.
The substrate and cover board is made of 3D printing.
Described connecting tube insert port or so is all provided with six, is arranged according to rectangular mode.
There is ramp type micro-fluidic chip insert port on the substrate.
There are many positioning methods, including rectangular preiection, left and right to position chuck, be bolted for substrate and cover board.
Apparatus of the present invention design is succinct, using 3D printing, realizes that inexpensive rapid processing, ramp type micro-fluidic chip are inserted
Entrance allows micro-fluidic chip to be smoothly inserted into, and will not damage, and rectangular preiection, is bolted so that base left and right positioning chuck
Plate and cover board are accurately positioned, and multiple connecting tube insert ports can meet the design requirement of different micro-fluidic chips in subsequent experimental.
The invention has the advantages that the process that cumbersome connecting fluid flows into pipe can be saved, it is only necessary to micro-fluidic
Chip is inserted into substrate cover upper cover plate and tightens fixing bolt, convenient succinct, ensures the quality of connection of connecting tube.
