Embodiment 1

[0016] Example 1 A microfluidic chip and its joint device based on the side hook structure

[0017] The invention provides a microfluidic chip and a joint device thereof, the structure of which is as follows: figure 1 As shown, the microfluidic chip has at least one fluid outlet located on the side wall of the chip; hooks are processed on the fluid outlet surface of the chip; the joint device consists of an elastic gasket, a catheter plug and a shell with a buckle structure.

[0018] More specifically, the buckle structure can be as figure 2 The three structures shown in , for example: cantilever type hook, ring type hook, ball type hook. That is, the hook on the microfluidic chip can be cantilever-shaped, circular-shaped or spherical-shaped, and the shell on the corresponding joint device is processed with a structure that complements it and can be locked tightly.

[0019] When in use, align the hook of the above-mentioned microfluidic chip with the slot of the shell and t...

Embodiment 2

[0020] Example 2 A microfluidic chip and its joint device based on the surface spherical hook structure

[0021] The invention provides a microfluidic chip and a joint device thereof, the structure of which is as follows: image 3 As shown, the microfluidic chip has at least one fluid outlet located on the side wall of the chip; the top and bottom of the chip are processed with spherical structures; the joint device consists of an elastic gasket, a catheter plug and a shell with a buckle structure.

[0022] When in use, align the hook of the above-mentioned microfluidic chip with the slot of the housing and insert it, then the spherical structure and the buckle structure in the joint device will be tightly locked, thereby realizing the fluid outlet of the microfluidic chip and the joint device. The elastic gasket is tightly fixed; the catheter connected to the external pump valve system or pipetting system is connected to the catheter plug, and finally the connection between t...

Abstract

The invention provides a lateral flow chip and its joint device. The lateral flow chip and its joint device are characterized in that the connection of the microfluidic chip and the joint device is realized by a specially designed buckle structure. The fluid outlet of the microfluidic chip is on the lateral side of the chip. The fluid outlet part of the microfluidic chip is designed with at least one cantilever type hook, annular hook or spherical hook connecting structure. During use, only by inserting the microfluidic chip into the joint device, can automatic fastening be realized, the operation is very simple, and the joint device can be used repeatedly.

Description

technical field [0001] The invention relates to the field of microfluidic chips, in particular to a lateral flow chip and a joint device thereof. Background technique [0002] Microfluidic chip technology has been widely researched and applied in biology, chemistry, medicine and other fields. In the practical application of microfluidic chips, the joint device of the microfluidic chip is a device that connects the internal channels of the microfluidic chip and the fluid pipelines such as external pump valves, and plays a very important role. However, the microfluidic chip joints widely used at present are mainly based on the use of curing glue such as epoxy to paste the fluid inlet and outlet of the microfluidic chip, or use a special custom-made splint combined with a screw fastening device for fixing. The above-mentioned chip connector device cannot be reused after being fixed, or the operation is slightly complicated, so it is difficult to popularize in the application o...
