A syringe-type device for inserting a catheter guide wire into a blood vessel includes a syringe in which the plunger has a central passage extending through it. A thin guiding tube with lateral holes is fixed to the syringe barrel tip and fits slidably in the central passage of the plunger. The plunger central passage is normally blocked by a closure valve.
When The needle is inserted into the blood vessel, plunger is then withdrawn somewhat to permit blood to be observed in the body of the syringe for verification of proper needle positioning. The guide wire advancer piece of the guide wire assembly is introduced and pushed inside the central tunnel of silicon valve. The piece will hold the advancer to work together as one piece. The tip of the advancer or the guide wire dispenser should first open the slot cut at of the valve . In this position, the central passage of the guide wire advancer is aligned and in communication with central passage of the plunger, the guiding thin tube and the needle lumen. The guide wire may then be fed into the blood vessel by advancing it through the central passage of the guide tube and the needle lumen.
Complete haemostatic advancement of guide wire into vessels
Avoid possible kinking of the guide wire while passing the valve.
Work with any guide wire size including the thin or fragile types
Keep the sensation of passing the wire into the vein with a feeling of any slight resistance
Detect arterial mis puncture through viewing the arterial pulsation at its piston pass way.
Can be used as a standard syringe to inject or aspirate
Plunger is made from Polypropylene
Piston & tube are made from Polycarbonate
Valves is made from Silicon
