Disposable anti-acupuncture intravenous infusion needle

Abstract

The invention discloses a disposable anti-acupuncture intravenous infusion needle, which comprises a needle base, a needle guard, a soft hose and a needle head, and further comprises a handle, a sliding piece and a limiting mechanism, wherein the needle guard covers the needle head; the soft hose and the needle base communicate; the needle base is of a cylindrical structure; one end of the needle base is fixed and communicates with the needle head and the other end of the needle base is connected to the soft hose; the sliding piece is of a cylindrical structure, and two ends of the sliding piece are provided with openings and the cross section of the sliding piece is represented as a rectangle; the handle is arranged at one end, close to the needle head, of the needle base; in the direction of the axial lead of the sliding piece, a rail groove is formed in one side of the sliding piece; the handle runs through the rail groove and is clamped in the rail groove in a sliding mode; the rail groove is longer than the needle head; the limiting mechanism is arranged on the sliding piece, the needle base and/or the handle; and a smooth convex part is arranged on the sliding piece in a surrounding mode. The needle head is sheltered since the sliding piece can slide on the needle base, so that the safety of needle head disposal after infusion is greatly improved; and the intravenous infusion needle, which avoids the use of a spring-type needle head, can reduce pain in patients.

Description

technical field [0001] The invention relates to a one-time use anti-acupuncture intravenous infusion needle. Background technique [0002] At present, the commonly used disposable venous needle needs to be covered with a needle cover to protect the needle before use, for example, to prevent the needle from being bent or collided. When in use, when the needle cover is pulled out, it is easy to cause the danger of stabbing, but the real danger is in the disposal stage after the infusion is completed. Putting on the needle cover is easy to be stabbed, causing serious consequences such as infection of medical staff. [0003] In response to this defect, some venous needles have adopted the technical means of retractable needles. After the infusion is completed, the needles are retracted into structures such as a protective cover for protecting the needles by utilizing the elastic force of structures such as springs. In this way, although the needle can be effectively protected ...
