Abstract

The invention discloses a disposable indwelling needle capable of preventing needle injury. The disposable indwelling needle comprises a catheter holder, a needle tube and a needle injury preventing protection device, wherein the needle injury preventing protection device comprises a casing and a leaf spring, a stop piece of the leaf spring cannot be closed in a natural state, and at least one bulge is formed on the inner wall of the casing and is in gradual change or sudden change design; the leaf spring has at least one bulge on an elastic arm, the casing has at least one clamping position matched with the bulge on the leaf spring, and the clamping position is used for fixing and locking the leaf spring and the casing; at least one concave part matched with the bulge on the leaf spring is formed in the inner wall of the catheter holder. When the needle tube is mounted in the leaf spring, the bulge on the leaf spring falls into the concave part of the catheter holder, so that the leaf spring and the catheter holder are fixed and locked, a needle tip is prevented from injuring a medical worker when pulled out, and the disposable indwelling needle can be widely applied to various clinic transfusion and vein indwelling.

Description

technical field [0001] The invention relates to a venous indwelling needle used for clinical patients belonging to the medical field, in particular to a disposable acupuncture-proof indwelling needle. Background technique [0002] Usually, most of the anti-acupuncture venous indwelling needles used in the medical field for infusion and venous indwelling of clinical patients do not have a relatively effective safety sheath. It will cause unnecessary injuries to personnel, and will also cause cross-infection of blood and germs, thereby increasing the danger and fear of medical staff's work. [0003] At present, many domestic medical device manufacturers produce this kind of anti-acupuncture venous indwelling needles, and most of the design principles rely on spring plates to seal the needle tip. And there is one or two or more blocking pieces on this spring leaf, under natural state, described blocking pieces are closed together. Therefore, when producing and assembling this...
