AI Technical Summary
Technical Problem
Existing IV catheter systems have limitations when connected to blood extraction devices, making it impossible to administer different medications and extract blood simultaneously, and the catheter is difficult to advance.
Method used
A catheter system was designed, including multiple ports and adapter structures, allowing simultaneous connection of blood extraction devices and fluid delivery devices, and facilitating smooth advancement of the flow tube and insertion of a fixation needle via flexible wings and Luer connectors.
Benefits of technology
This allows for simultaneous blood extraction and fluid delivery, enhancing the flexibility and safety of the catheter system and reducing the risk of accidental needlestick injuries.

Abstract
A catheter system is provided, comprising a catheter and a first catheter adapter having an adapter body and adapter wings. The catheter body includes a distal port, a proximal port, and a side port, wherein a proximal end of the catheter is secured to the distal port, and the side port includes a Luer connector. The adapter wings engage with the adapter body and include a first flexible wing and a second flexible wing configured to contact each other when a clamping force is applied thereto. An extension tube is connected to the proximal port, and a second catheter adapter is connected to the proximal end of the extension tube. A blood aspiration device is coupled to the side port and includes a flow tube configured to extend distally from the blood aspiration device, through the first catheter adapter, and into the catheter to perform blood aspiration.
