Abstract
The utility model discloses a disposable venous indwelling needle which comprises a puncturing indwelling unit, an outer liquid infusion unit and a connecting pipe connecting the puncturing indwelling unit and the outer liquid infusion unit. The puncturing indwelling unit comprises a puncturing component for punching the body surface of a patient and an indwelling component indwelled inside the patient body. The puncturing component is inserted into the indwelling component in a sealed mode and capable of being removed from the indwelling component. After the puncturing component is removed from the indwelling component, an infusion channel for circulation of outer liquid is formed in the indwelling component. The connecting pipe is connected on the indwelling component and communicated with the infusion channel. The disposable venous indwelling needle is reasonable in structure, strong in practicability, and capable of effectively solving the problems that a infusion connector is likely to prick or puncture medical staff by a needle, bring in sealed material particles on a heparin cap and cause serious or potential hematogenous pathogen infection.
