Embodiment Construction

[0031] Such as figure 1 and figure 2 Shown, a kind of sample collecting and adding system for micro-control flow chip experiment of the present invention includes sampling and adding device 3 and sampling auxiliary device. Such as Figure 4 As shown, the sampler 3 is small in size and can be docked with the sample port 11 on the chip 10 after collecting the sample, so as to effectively avoid contamination of the sample during transfer and improve detection efficiency. In order to overcome the difficulty and inconvenience of direct sampling through the sampling and adding device 3 due to the small size of the sampling and adding device 3 , the sampling and adding device 3 can be assembled in the tube body of the sampling auxiliary device. The experimenter can control the sampling injector 3 to perform stable sampling only by turning the sampling actuator 4 installed on the side of the tube, and precisely control the sampling volume through the sampling volume adjustment devi...

Abstract

The invention relates to the field of microfluidic chip experiment auxiliary apparatuses, in particular to a sample sampling and adding system for a microfluidic chip experiment. The system comprisesa sampling and adding device, and a sampling auxiliary device for assisting the sampling and adding device to sample; the sampling and adding device comprises a sample tube, a pushing rod inserted atthe terminal end of the sample tube in a slide manner, and a sampling needle connected with the head end of the sample tube in a detachable manner, the sample tube is provided with an assembling protrusion for cooperation installation with the sampling auxiliary device, and the pushing rod is provided with a pushing cap for pushing the pushing rod to slide by the sampling auxiliary device for sampling; and the sampling auxiliary device comprises a tube body, and a sampling execution apparatus and a sampling amount adjusting apparatus arranged on the tube body. The system can facilitate an experimenter to use the sampling and adding device to perform sampling and add a sample to a chip.

Description

technical field [0001] The invention relates to the field of microfluidic chip experiment auxiliary devices, in particular to a sample collection and loading system for microfluidic chip experiments. Background technique [0002] Microfluidic chip is a new detection technology that reduces the process of biological and chemical experiments to a chip of a few centimeters for automated experiments and analysis. Sampling and sample injection are an important part of microfluidic detection. Most of the existing sampling devices for microfluidic chips are manual sampling and sample addition. Patent 201910123188.1 discloses a sample sampling and sample addition method. Although it can control the sampling volume more accurately, it cannot meet the requirements of microfluidic automatic detection; patent 201710317096.8 discloses an automatic sampling system based on a microfluidic chip, and the sampling and adding system Separation, using negative pressure automatic sampling, its ...
