Abstract
The utility model relates to a single-pore micro biochip. A hollow part is formed between an upper cover and a bottom and filled with a chip membrane and a water absorbing material; the upper cover is provided with micro pores; an air hole is formed below each micro pore; a boss frame is arranged on the circumference of each micro pore; a rib plate frame is arranged on the circumference of each micro pore on the back of the upper cover; and a bayonet and a clamping table are arranged on each of four walls of each single-pore micro chip. The single-pore micro biochip overcomes the defects that the biochip in the prior art is high in manufacturing cost, can be operated by only one person every time, is long in reaction time, low in efficiency and high in consumption of detection reagents and samples to be detected, is not suitable for simultaneously detecting a large batch of samples at one time and the like. The single-pore micro biochip integrates the advantages of operation flexibility of a single-pore biochip and low consumption of detection reagents and samples, low cost, short reaction time and high efficiency of a multi-pore micro biochip; and the application range of the chip is enlarged.
Description
Technical field
The utility model relates to a kind of biochip, particularly a kind of single hole micro-biochip.
Background technology
Before the present utility model, existing biochip is mainly single hole chip and porous micro-biochip.The single hole chip is made of loam cake and going to the bottom, and the centre is filled with related chip film and water-absorbing material, on cover and offer funnel shaped hole, general size is 1 square centimeter, offers corresponding infiltration, breather hole below the hole, as shown in Figure 1.This chip manufacturing cost is high, can only carry out single part of operation at every turn, long reaction time, and efficient is low, and detection reagent and sample to be tested consumption are large, are not suitable for the disposable sample in enormous quantities that detects simultaneously, such as blood station examination, crowd's health check-up, inspection and quarantine etc.Porous micro-biochip is characterised in that to cover and is provided with a plurality of micropores, and the periphery of each micropore arranges the boss frame, at the periphery of each micropore of the loam cake back side floor frame is set, as shown in Figure 3.This chip can cause unnecessary waste when detecting the sample of short run.
Summary of the invention
The purpose of this utility model is to overcome defects, designs a kind of single hole micro-biochip.
The technical solution of the utility model:
The single hole micro-biochip, hollow space at loam cake, between going to the bottom, be filled with chip film, water-absorbing material, on cover and be provided with micropore, the micropore below is provided with breather hole, its technical characteristics is that the micropore periphery arranges the boss frame, at the periphery of each micropore of the loam cake back side floor frame is set, and each single hole microchip wall arranges bayonet socket and Ka Tai.
Advantage of the present utility model has had both single hole biochip flexible operation and porous micro-biochip detection reagent and the sample consumption is few, cost is low, the reaction times is short, efficient is high advantage, has further enlarged the range of application of chip.

Embodiment
As shown in Figure 2:
Offer micropore 1 on the loam cake 8, up big and down small, be ladder structure, i.e. doline, top specification 4 * 4mm; In order to prevent the impact of stretching of liquid between each micropore 1, at the periphery of each micropore 1 boss frame 2 is set, boss frame 2 is square, high 2mm, thick 0.5mm; For guaranteeing the relatively independent interference that is not subjected to other micropores 1 of its reaction compartment, in micropore 1 position at loam cake 8 back sides floor frame 4 is set; Columniform small boss 3 is set, each micropore 1 corresponding 2 small boss 3, minute left and right two settings (omit among the figure, only drawn), diameter 1mm, high 4.5mm in each micropore 1 corresponding position of going to the bottom on 9 with top; With top each micropore 1 corresponding position (infiltration) breather hole 5 is set in 9 cross sections of going to the bottom, each micropore 1 arranges 2 breather holes 5 (omit among the figure, only drawn), and breather hole 5 plays infiltration and breathes freely diameter 1mm; Below each micropore 1 and for loam cake 8 back side hollow spaces 6, i.e. the chip film of floor frame 4 interior space-filling dimensions, water-absorbing material etc.; A card platform 10 is set on loam cake 8 inboards, and 9 upper outside of going to the bottom arrange bayonet socket 7, and bayonet socket 7 is stuck on the card platform 10, and loam cake 89 is fixedly connected with going to the bottom; Hollow space be by loam cake 8, go to the bottom 9 and left and right floor frame 4 consist of.
As shown in Figure 3:
It is the biochip of 48 micropores.The single hole micro-biochip arranges supporting draw-in groove 11 and lesser calorie platform 12 at wall on the basis of porous micro-biochip structure, specification for long * wide * dark: 2 * 1 * 1mm, its structure as shown in Figure 4.
The explanation of the utility model application process:
During use, can be according to number of awaiting test sample, the single hole micro-biochip of respective numbers is connected with Ka Tai by draw-in groove, as shown in Figure 5, be the biochip of 12 micropores being combined into by the single hole micro-biochip, can 12 samples of disposable detection.
