Indwelling transfusion needle with hose

Abstract

The invention discloses an indwelling transfusion needle with a hose. The indwelling transfusion needle with a hose comprises a transfusion needle assembly and a protection assembly, wherein the transfusion needle assembly comprises a steel transfusion needle, a connecting pipe, a small transfusion tube and a needle base; the steel transfusion needle, the connecting pipe, the small transfusion tube and the needle base are sequentially connected; the protection assembly comprises an indwelling hose, a wing base and a protective tube; the indwelling hose is connected with one end of the wing base and the other end of the wing base is connected with one end of the protective tube; the steel transfusion needle extends into the protective tube from the other end of the protection tube and passes through the wing base and the indwelling hose; the connecting pipe is located in the protective tube; a flaky fixed wing is arranged on the wing base; the indwelling hose is inserted into a vein vessel of a human body along with the steel transfusion needle during transfusion and pulls the small transfusion tube, the steel transfusion needle returns to the protective tube and the connecting pipe is clamped and fixed by the protective tube. The indwelling transfusion needle with a hose has the characteristics of being simple in structure, low in cost and convenient to operate, and has a protection effect on a patient and an operator.

Description

technical field [0001] The invention relates to a medical device, in particular to an infusion needle. Background technique [0002] The infusion needle cooperates with the infusion set for infusion, and is also used for drawing blood in blood vessels. The existing infusion needles are composed of steel needles (puncture needles), Unicom tubes (needle handles), small infusion tubes and needle holders. Infusion needles have made great contributions to human health and are used in a huge amount. There are about 8 billion infusion needles, plus the infusion needles used for blood drawing, the annual production and sales are about 10 billion. However, there are still serious defects in the product with such a large dosage: during infusion, the steel needle is left in the blood vessel, which often stabs or punctures the blood vessel, which needs to be replaced and re-operated, and even causes medical accidents. When the needle is pulled out, the steel needle often stabs the nur...
