Needleless connection type infusion apparatus

Abstract

The invention provides a needleless connection type infusion apparatus. The needleless connection type infusion apparatus comprises an infusion catheter and an intravenous infusion needle between which a connection pipe is arranged; an external taper joint in match with an intravenous infusion needle holder is arranged at the rear end of the connection pipe; the front end of the connection pipe is connected with the infusion catheter through an one-way valve; a branch pipe is arranged on the connection pipe; the distance from the part in which the branch pipe is connected with the connection pipe to the one-way valve is less than 10cm, and the distance to the external taper joint is less than15cm; a rubber plug on which a liquid inlet channel is positioned is arranged in the branch pipe; an elastic valve in match with an infusion needle is arranged on the top of the liquid inlet channel; the elastic valve can be automatically closed after the infusion needle is pulled out. According to the needleless connection type infusion apparatus, medicine liquid is quickly added to the connection pipe through the infusion needle without a steel needle, the one-way valve at the front end of the connection pipe can prevent the medicine liquid from reverse flowing, thus the medicine liquid can quickly enter a human body; in addition, the infusion needle without the steel needle can prevent a nurse from being punctured to cause cross infection.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a needleless connector type infusion set. Background technique [0002] Clinically, it is often necessary to push the medicine to the patient through the infusion set. Usually nurses disconnect the connection between the intravenous needle and the infusion catheter, and push the drug statically from the needle seat of the intravenous needle, but this method will cause air bubbles to be generated when the intravenous needle and the infusion catheter are reconnected, and the operation is troublesome, which increases the nurse's workload. workload, and even delayed the best time to rescue. For infusion sets with injection parts, nurses will also add medicine from the injection part, but when adding medicine from the medicine filling part, the liquid medicine tends to flow upwards, and the position of the medicine filling part is not reasonable enough, so the medicine liquid cannot ...

AI Technical Summary

Problems solved by technology

Usually nurses disconnect the connection between the intravenous needle and the infusion catheter, and push the drug statically from the needle seat of the intravenous needle, but this method will cause air bubbles to be generated when the intravenous needle and the infusion catheter are reconnected, and the operation is troublesome, which increases the nurse's workload. workload, even delayed the best time to rescue

For infusion sets with injection parts, nurses will also add medicine from the injection part, but when adding medicine from the medicine filling part, the liquid medicine is easy to flow upward, and the position of the medicine filling part is not reasonable enough, and the medicine liquid cannot quickly enter the human body

And use a syringe with a steel needle for puncture, the steel needle may puncture the nurse and cause cross-infection

During the puncture, puncture debris from the puncture interface will enter the fluid circuit and blood circuit, and may increase the risk of microorganisms entering the fluid circuit and blood circuit
