Abstract

The invention relates to a needleless dosing positive pressure connector. The positive pressure connector can be mainly used for liquid injection, gravity transfusion and liquid extraction and is connected with a venous transfusion tube, ductus venosus and the like and started through a luer connector. A rubber plug of the positive pressure connector of the invention is opened to realize the liquid flowing in a single direction and avoid the pollution of particles, micro-fragment and the like caused by needle puncture. When an injector is removed, the positive pressure connector generates a positive pressure to make the liquid inside the positive pressure connector automatically advance and prevent blood from returning to a remaining needle and forming thrombus, so that the blockage of the remaining needle is prevented.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a needle-free positive pressure connector for drug dosing that generates positive pressure during infusion and prevents blood backflow. Background technique

[0002] When the patient has multiple infusions, the indwelling needle is usually used, and the connector of the syringe is generally used to connect the indwelling needle. However, when the infusion is completed and the connector of the syringe is pulled out, the blood will flow back into the indwelling needle due to the negative pressure and will not flow. The blood of the patient is easy to coagulate, and the blood coagulation will cause the blockage of the indwelling needle, and the next infusion will not be able to proceed. Contents of the invention

[0003] The purpose of the present invention is to provide a positive pressure joint for needle-free drug dosing in order to solve the above problems. When the syringe is p...
