AI Technical Summary

Technical Problem

In existing technologies, it is difficult to guarantee the consistency and efficiency of the assembly positions of the chip and the loading nozzle. Manual loading requires a high level of skill, while instrument loading is inefficient and requires specialized equipment.

Method used

A sample loading device was designed, including a base and a pressure cap. The relative positions of the chip and the loading gun head are constrained by the positioning chamber and the positioning port. The stability is improved by combining the guide cavity and the reinforcing ribs. The locking structure ensures fixation. The transparent structure facilitates observation and operation.

Benefits of technology

It improves the consistency and efficiency of chip and loading nozzle assembly, simplifies the operation process, reduces costs, and increases the success rate of sample loading.

Abstract

The utility model provides a sample loading device which is used for assisting a loading gun head in loading a sample to a chip. The chip is used for gene sequencing. The sample loading device comprises a base and a gland. The base is provided with a positioning bin. The positioning bin is configured to accommodate at least part of the chip. The gland is movably connected to the base. The gland is configured to prevent the chip from separating from the positioning bin. The gland is provided with a positioning opening. The positioning opening communicates with the positioning bin. And the positioning opening is configured to allow the loading gun head to pass through. According to the sample loading device provided by the invention, the assembly position consistency and the assembly efficiency of the chip and the loading gun head are improved.
