Puncture-preventing entry needle

Abstract

The invention discloses a puncture-preventing entry needle, which comprises a needle body, a needle base, a container and a spiral tension spring, wherein the container comprises a shell and a safe helmet, the shell comprises a cylinder wall and an end plate; the end plate is provided with a needle hole; the inside of the end plate is provided with a safe helmet; the safe helmet comprises a baffle and an elastic arm; when the elastic arm is in a free state, one side of the baffle is in elastic contact and connection with the inner wall of the cylinder wall, the baffle covers the needle hole; when the needle body penetrates into the needle hole, the side edge of the baffle does not contact the inner wall of the cylinder wall; the spiral tension spring and the needle body are coaxially arranged; when the spiral tension spring is in a free state, the container contacts the needle base, the needle body penetrates through the needle hole; after the puncture-preventing entry needle is used, the container is arranged at the needle tip, the needle body retreats out of the needle tip, and the baffle covers the needle hole. By using the puncture-preventing entry needle disclosed by the invention, the container can prevent the needle tip from penetrating from the needle hole after the puncture-preventing entry needle is used, so that the accident that a person is hurt by the entry needle can be avoided, the puncture-preventing function is reliable and the effect is remarkable.

Description

technical field [0001] The invention relates to an injection needle, in particular to a stab-proof injection needle. Background technique [0002] Current injection needles are contaminated with body fluids of patients after use. Since the sheath of the used injection needle has been discarded, the sharp needle tip is always exposed during the whole process of the used injection needle as medical waste circulation. Once the needle tip stabs medical staff, medical waste disposal personnel and other related personnel, it will be Cause the spread risk of various bodily fluid-borne diseases, and produce serious hospital source safety accidents. The structure of the injection needle provided with the anti-stab device is too complex at present, and the manufacturing cost is high, so it cannot be popularized and used. Contents of the invention [0003] In order to solve the problems that the current injection needles equipped with anti-stab devices are too complicated in struct...
