  • Subcutaneous injection set tubing with solvent bonding
    Patent number: 6673440
    Abstract: The infusion set comprises of a connecting tube of polyethylene which is treated to form a wetable surface or treated with a primer and then bonded to a PVC hub by using solvent adhesive to solvent bond the low density polyethylene tubing or Teflon tubing to a PVC hub. The surface treatment methods include a methane plasma surface that is applied to tubing in a continuous manner and alternatively a primer that is applied locally and dried prior to applying the adhesive. Both techniques form a strong and resilient bond for the infusion needle and tube when assembled to the PVC hubs.
