AI Technical Summary
Technical Problem
In the prior art, it is difficult to effectively remove air before inserting the catheter into the patient's vasculature, which may cause bubbles to enter the vasculature, forming an embolism, and causing patient injury.
Method used
A conduit system is designed, including a conduit assembly, a needle assembly, a needleless connector and an exhaust assembly. Through the actuation and pre-infusion process of the exhaust assembly, threaded connections and raised structures ensure reliable opening of the valve and effective removal of air.
Benefits of technology
It realizes safely removing air before the catheter is inserted into the patient's vasculature to prevent air bubbles from entering and ensuring patient safety.

Abstract
A catheter system that can include a needleless connector, the needleless connector can include a distal end, a proximal end, and a valve disposed between the distal end of the needleless connector and the proximal end of the needleless connector. The catheter system can include an exhaust assembly, the exhaust assembly can include a proximal member and a distal member. The proximal member can include a male luer adapter, the male luer adapter can include a male luer. The distal member can include a distal end coupled to the proximal end of the needleless connector and a proximal end coupled to the male luer adapter. In response to the proximal member moving from a proximal position to a distal position relative to the distal member, the male luer of the male luer adapter can open the valve to exhaust air inside the catheter system.
