ABSTRACT:
A catheter placement unit comprising a Y adapter with a side port for coupling a catheter tube to a fluid infusion unit and including a resilient sleeve within the axial bore of the Y adapter at the proximal end of the catheter placement unit through which a piercing needle or the like snugly passes in the initial assembled condition. A manually compressible mechanism circumscribes the resilient sleeve and, upon proper setting preferably before but also after venipuncture and needle removal, squeezes the resilient sleeve to firmly occlude the inside passage of the resilient sleeve to prevent fluid loss.
