Description

Technical Field

[0001] The utility model relates to the technical field of microfluidic chip equipment, in particular to a multi-channel sampling microfluidic chip equipment. Background Art

[0002] Multi-channel sampling microfluidic chip devices are precision fluid manipulation devices implemented using microfluidics technology. They can simultaneously process and analyze multiple fluid samples on a miniaturized platform. Especially in the fields of biology, chemistry, and medicine, multi-channel sampling microfluidic chip devices provide an efficient, precise, and reliable method for fluid processing. This device not only greatly improves experimental efficiency but also, due to its miniaturization and integration, shows great potential in research and application in various fields.

[0003] During the use of existing microfluidic chip equipment, hoses are used as connecting pipes, which are easy to adjust and bend and can flexibly adapt to various sampling needs. Due to the long length of the hoses, if they are not stored and managed in a standardized manner, they will inevitably become entangled and knotted during long-term use. If the hoses are entangled together, they may hinder the flow of fluid inside the device and affect the sampling effect. The entangled hoses are also more susceptible to external contamination, affecting the accuracy of the experimental results, thereby reducing the practicality of the equipment, and need to be optimized and improved.
