Novel exhaust-free infusion set

Abstract

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.

Description

technical field [0001] The invention belongs to the class of medical instruments, in particular to a novel exhaust-free infusion set. Background technique [0002] We know that disposable infusion sets are commonly used medical devices, which generally include bottle stopper piercers, drip funnels, liquid flow regulators, liquid medicine filters, and intravenous infusion needles, which are connected in series by infusion catheters. The medicinal liquid flows in through the bottle stopper piercer, flows into the infusion catheter through the outlet of the dropping funnel, and enters the human body through the medicinal liquid filter and the intravenous infusion needle. In the initial stage of the infusion of the traditional infusion set, since the infusion conduit at the back of the dropping funnel is empty, the liquid medicine enters the infusion conduit directly from the bottom of the dropping funnel drop by drop. There is air, and before the next drop of medicinal liquid ...

AI Technical Summary

Problems solved by technology

Therefore, in the process of infusion, in order to prevent air from entering the human body, the nurse will empty the liquid medicine with air embolism, which not only wastes the medicine liquid, brings economic burden to the patient, but also wastes time and increases the labor intensity of the medical staff.

[0003] The current infusion set and drip funnel do not have the function of avoiding exhaust at the initial stage of infusion
