Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, a device for holding a pesticide residue detection chip comprises a chip fixing seat 21 and a detection chip 11, wherein the chip fixing seat 21 comprises a supporting plate 31 and an upper seat 32 arranged at the center of the supporting plate 31, the detection chip 11 comprises a substrate 41 and a tube body 42 arranged on the substrate 41, at least one hole 33 is arranged on the periphery of the upper seat 32, a steel ball fixing seat 23 is arranged in the hole, a spring 22 is fixedly connected in the steel ball fixing seat 23, the spring 22 is fixedly connected with a steel ball 24, and at least one elongated slot 43 extending to the tube opening of the tube body is arranged on the inner wall of the tube body 42.
The detection chip adopts a microfluidic chip, each layer of the detection chip is provided with a microchannel, an extraction pool, a detection pool, a distribution pool and a sample inlet hole by micromachining technology, each layer is formed by hot-press bonding, and the detection is carried out by adopting methods such as chromatography, enzyme inhibition method, immunity method and the like.
It should be noted that, the shapes of the supporting plate 31 and the substrate 41 are not limited by the attached drawings, when the detection chip needs to be rotated, the supporting plate 31 and the substrate 41 may be in a disc shape, the upper seat may be a cylinder or a circular tube, and the periphery of the cylinder or the circular tube needs to have a hole space for accommodating the steel ball fixing seat.
In this embodiment, the support plate is integrally connected with two columns 34 at least at the periphery, the substrate is provided with corresponding limiting holes 44, and the columns 34 are installed in the limiting holes 44.
When the device is used, the steel ball fixing seat 23 with the steel balls 24 is firstly placed in the hole position 33 on the periphery of the upper seat 32 of the chip fixing seat 24, then the two columns 34 of the supporting plate 31 correspondingly extend into the limiting hole 44 on the substrate 41 for fixing, simultaneously, the steel balls 24 slide in along the long groove 43 on the inner wall of the detection chip tube body 42, and the steel balls 24 push against the long groove 43 to realize circumferential fixing of the detection chip due to the outward supporting force of the spring 22 on the steel balls 24.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
