Problems solved by technology

This patent uses a syringe pump to inject samples, but this patent causes large fluctuations in sample injection. At the same time, the sample must be sucked into the syringe before it can pass into the chip. This method is likely to cause a large number of samples to remain in the syringe and the pipeline leading to the chip. A lot of waste is caused. In addition, this method is cumbersome to assemble, easy to introduce air bubbles, and difficult to achieve sterilization

Abstract

The invention relates to a hydraulic sampling device and a hydraulic sampling method for treating a biological sample solution microfluidic chip. The hydraulic sampling device comprises a liquid container(1) which contains an incompressible liquid immiscible with a sample solution; a power source(2) which drives the liquid to enter a buffer bottle(4) through an input pipe(3); and the buffer bottle(4) containing a sample solution to be injected; when the power source(2) drives, the liquid enters the buffer bottle(4) via the input tube(3) to increase the hydraulic pressure, so that the sample solution stably and controllably enters the microfluidic chip(6) via an output tube(5).

Description

technical field [0001] The invention relates to the field of microfluidic chips, in particular to a hydraulic sampling device and a hydraulic sampling method for processing a sample solution microfluidic chip. Background technique [0002] Microfluidic chip technology is widely used in sample preparation, reaction, separation, and detection in biological, chemical, and medical analysis processes. It is one of the most rapidly developing cutting-edge technologies and the most active fields of research. The microfluidic chip that processes the sample solution has high requirements on the stability of sterilization and sample injection. The sample injection of the microfluidic chip needs to be slow, such as at the pL-nL / s level. The stability is higher, and slight fluctuations will affect the stability and uniformity of the droplets. [0003] The amount of sample used in microfluidics is very small, and it is often kept at the microliter level. At present, microfluidic chips o...
