specific Embodiment approach 1

[0018] Specific implementation mode 1: This implementation mode is a quick connector of a microfluidic system, such as Figure 1-Figure 3 , which is specifically composed of a one-way valve, a compression clamp 4, a sealing ring 5 and a switch rod 6;

[0019] The one-way valve is composed of a valve body 1, a spring 2 and a spherical valve core 3;

[0020] The two ends of the valve body 1 are respectively the inlet 1-1 and the outlet 1-2 of the one-way valve, and the diameters of the inlet 1-1 and the outlet 1-2 of the one-way valve are smaller than the diameter of the middle part;

[0021] The spherical valve core 3 is arranged inside the middle part of the valve body 1 and close to the outlet 1-2 of the one-way valve, the spring 2 is arranged inside the middle part of the valve body 1 and close to the inlet 1-1 of the one-way valve, and the spring 2 is under compression state, the two ends of the spring 2 press the spherical valve core 3 and the inlet 1-1 of the check valve...

specific Embodiment approach 2

[0029] Embodiment 2: This embodiment is different from Embodiment 1 in that: the material of the clamp 4 is stainless steel or plastic. Others are the same as the first embodiment.

specific Embodiment approach 3

[0030] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the sealing ring 5 is made of rubber. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a quick connector of a microfluidic system, and relates to a connecting device of the microfluidic system. The invention is aimed at solving the technical problems that a connecting port between an existing microfluidic device and an external pipeline is difficult to realize automatic connection, the connection precision is low, the required time is long, the connecting port is prone to leaking, and cross contamination between liquids is prone to occuring. The quick connector is composed of a one-way valve, a pressing clamp, a sealing ring and a switch rod; a sphericalvalve core is fixed on one end of the switch rod through the outlet of the one-way valve, and the sealing ring is arranged on the outer wall of the outlet of the one-way valve; and the pressing clampis clamped on the outer wall of the outlet of the one-way valve, the pressing clamp is in close contact with the sealing ring, and the pressing clamp is closer to the spherical valve core than the sealing ring. The quick connector of the microfluidic system is simple in structure and convenient to manufacture and use, a micro-channel inlet is connected in a pressing and connecting mode, and the quick connector is automatically opened or closed without rotating or inserting link.

Description

technical field [0001] The invention relates to a quick connector of a microfluidic control system, which belongs to the technical field of microfluidic control. Background technique [0002] Microfluidic systems are widely used in micro-drug injections, microfluidic chips, micro-water administration, micro-fluid analysis, and micro-sampling in biomedical analysis. In the application process, it is often necessary to quickly and efficiently inject the liquid sample or reaction solution, cleaning solution, etc. into the microfluidic device through an external pipeline. The current connection interface mainly uses steel pipes or joints to manually insert or rotate the inlet of the microfluidic device base flow channel made of materials such as PDMS or PMMA. It takes a long time and the connection accuracy is low, and it is difficult to realize automatic connection. Since the current crimp-type joints are not quick-change joints, when the joints are disengaged, the reagents ar...
