Technical background：

Infusion extension tube is an indispensable tool for medical staff when using microinjection pump, which is widely used in clinic. The traditional extension tube is connected at both ends with internal and external conical joints, which are mainly suitable for intravenous infusion. When the medical staff need to use the extension tube to inject drugs into the oral cavity of the patient, the external conical joint will cause the patient to have heavy foreign body sensation, poor comfort, and easy to fall off. If the radioactive residue in the extension tube cannot be rinsed out during the oral infusion of radioactive drugs to patients, the imaging agent will be wasted and the radiation pollution to the environment will be large. At the same time, the actual dose will be insufficient, resulting in poor image quality and affecting the accuracy of quantitative analysis results.
