AI Technical Summary
If a patient moves around during an IV infusion, the IV needle may fall out of the IV bag outlet, affecting the normal infusion procedure.
An anti-dislodgement device for infusion tubing was designed. It uses components such as a slot, a rotating block, a screw, and a fixing mechanism to fix the position of the infusion tube needle and prevent it from dislodging from the outlet of the infusion bag.
It effectively secures the infusion needle, preventing it from coming off the outlet when the patient moves, thus improving the stability and compatibility of the infusion.
