The invention relates to a novel exhaust-free
infusion set, which comprises a
bottle plug puncture outfit, a dropper, a liquid
medicine filter and a venous infusion needle. The
bottle plug puncture outfit, the dropper, the liquid
medicine filter and the venous infusion needle are connected in series by infusion catheters. A flow
regulator is mounted on the outside of the
infusion catheter between the dropper and the liquid
medicine, a liquid guide two-way joint is arranged on the lower portion of the dropper, the upper portion of the liquid guide two-way joint extends into the dropper, the outer wall of the lower portion of the liquid guide two-way joint is fixed with a lower orifice of the dropper in an adhering manner, the lower end of the liquid guide two-way joint extends out of the dropper to be communicated with the
infusion catheter below the dropper, an exhaust and guide slot communicated with the center through hole of the liquid guide two-way joint are axially arranged on the upper portion of the liquid guide two-way joint, and a cap is arranged at the upper end of the liquid guide two-way joint. Air-bearing liquid medicine in the infusion catheters can be avoided, and
air bubble exhausting during infusion can be avoided. By the novel exhaust-free
infusion set which is reasonable in structure, convenient in use and operation, time-saving and labor-saving and perfect, labor intensity of
medical staff is reduced,
nursing time is saved and safety in infusion is higher.
