The hydraulic system is an important part of the fully automated in vitro diagnostic equipment and a key factor determining the performance of the in vitro diagnostic equipment. The hydraulic system usually uses joints to connect multiple connecting pipes in series or in parallel to form multiple pipelines. The sealing performance between the joints and the connecting pipes is the prerequisite for ensuring the normal operation of the equipment.

The traditional intubation method is to manually insert the connecting tube and the connector into one body. When the force of both hands exceeds 0.7kg during insertion, the operator will experience hand fatigue. However, when the connector and the connecting tube are inserted, 0.9 kg is required. ~1.9kg of external force, so manual intubation is likely to cause hand fatigue and low intubation efficiency. At the same time, due to the smooth surface and small size of the joint, it is difficult to intubate, and it is easy to slip during insertion, resulting in joint breakage or accidental injury to the operator. Therefore, at present, in manual intubation, heating and softening the connecting tube or spraying alcohol is usually used to reduce the intubation force, but softening the connecting tube or spraying alcohol is still difficult to handle, and the softened connecting tube is prone to non-rebounding of the connecting tube Phenomenon, affecting the sealing performance of joints and connecting pipes. For this reason, how to design an automatic intubation machine that can realize automatic insertion and ensure the sealing performance of the insertion is an important problem to be solved urgently by those skilled in the art.
