Description
Technical field
The present invention relates to a kind of based on the 3D micro-fluidic chip clamp experiment porch printed, specifically, it is that 3D printing technique is applied in the making of micro-fluidic experiment porch, realize the rapid processing of experiment porch, reduce cost of manufacture, purpose easy and simple to handle, this fixture experiment porch is applicable to biomedical detection and the chemical analysis application of various employing micro-fluidic chips, belongs to microfluidic art.
Background technology
3D prints the one belonging to rapid shaping technique, and its central principle is: " Layered manufacturing, successively superposition ".The printed material of 3D printer is the raw material of device, such as metal, pottery, plastics, sand etc..The process of implementing is to utilize computer-aided design or modeling software to commodity modeling, then model division is become cross section successively, generates STL standard data file.3D printer, by identifying file middle section information, successively prints and bonding, produces entity.It is widely used in the fields such as automobile, aviation, medical treatment, building at present.Its principle increasing material manufacture is greatly saved material, reduces product cost, constant product quality.But for the product that required precision is significantly high, it is necessary to follow-up polishing and polish；Because in the course of processing, material is heated repeatedly, therefore interiors of products stress is complicated, product material poor-performing, for instance intensity, rigidity etc..So, it is highly advantageous that 3D prints product not high for required precision, that product strength requirement is not high yet.
Microfluidic chip technology is one of focus of present analysis science research.Micro-fluidic chip is that the basic operation units such as biology, chemistry, the sample preparation of medical analysis process, reaction, separation, detection are integrated on the chip of one piece of micro-meter scale, is automatically performed analysis overall process.Microfluidic chip analysis is with chip for operating platform, simultaneously based on analytical chemistry, with micro electronmechanical process technology for relying on, with microchannel network for architectural feature, with life sciences for currently mainly application, is the emphasis of current micro-total analysis system field development.And laboratory is when carrying out micro-fluidic chip experiment, it is necessary to by connecting tube, fluid is imported in micro-fluidic chip, therefore experiment is required for connecting connecting tube at each interface every time, is sealed simultaneously.Each micro-fluidic chip has some interfaces, and excuse size is little, so adapter operation can consume the plenty of time when experiment, and quality of connection is relevant to manual operation stability, seepage and blocking easily occurs.The unreasonable arrangement of connecting tube also can affect laboratory observation and result.
Summary of the invention
In order to overcome micro-fluidic chip connecting tube in existing laboratory work to rely on the problem that experimenter's operating experience, length consuming time and connection procedure are loaded down with trivial details, the present invention provides a kind of based on the 3D micro-fluidic chip clamp experiment porch printed, experimenter should be not only assisted in based on the 3D micro-fluidic chip clamp experiment porch printed and quickly connect the connecting tube of turnover micro-fluidic chip, and can guarantee that quality of connection, operation is simple.
The technical solution adopted for the present invention to solve the technical problems is: of the present invention based on the 3D micro-fluidic chip clamp experiment porch printed, including substrate, cover plate, bolt connecting hole, substrate and cover plate two parts are experiment porch agent structure, two parts are bolted, substrate and cover plate central leave the rectangular window of formed objects, and four bolt holes, four rectangular preiection location are arranged, substrate has ramp type micro-fluidic chip insert port, there is location, left and right chuck inside, cover plate is each side distributed six connecting tube insert ports and sealing ring installation site.
Described substrate and cover plate print by 3D and make.
It is all provided with six about described connecting tube insert port, arranges according to rectangular mode.
Described substrate has ramp type micro-fluidic chip insert port.
Substrate and cover plate have multiple positioning modes, connect including rectangular preiection, location, left and right chuck, bolt.
Apparatus of the present invention design is succinct, available 3D prints, realize low cost rapid processing, ramp type micro-fluidic chip insert port makes micro-fluidic chip to insert smoothly, it is damaged from, rectangular preiection, location, left and right chuck, bolt connection make substrate and cover plate be 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 beneficial effects as follows, it is possible to save the loaded down with trivial details fluid that connects and flow into the process of pipe, it is only necessary to micro-fluidic chip is inserted substrate cover upper cover plate and tightens fixing bolt, convenient succinct, it is ensured that the quality of connection of connecting tube.
