AI Technical Summary
Technical Problem
During the blood drawing process using existing intravenous catheters, blood can easily contaminate the adapter and needleless connector, increasing the number of operation steps and posing a risk of hemolysis.
Method used
An inserter is designed, comprising convex and concave ports, a middle portion having a slender tubular shape and a tapered or stepped structure, a septum sealing the concave port, an adapter for inserting a catheter system, and a needle-free connector to reduce blood contact.
Benefits of technology
The design of the insert reduces the exposure of blood to the adapter and needleless connector, lowers the risk of hemolysis, simplifies the operation steps, and improves operational safety.

Abstract
An insert for a catheter system may include a distal end, a proximal end, and an intermediate portion disposed between the distal and proximal ends. The distal end of the insert may include a male port, and the proximal end of the insert may include a female port opposite the male port. The insert may be configured to extend through an adapter and / or a needleless connector of the catheter system to reduce exposure of the adapter and / or the needleless connector to blood that may flow through an inner lumen of the insert. The inner lumen of the insert may extend through the male port, the intermediate portion, and the female port.
