Blood taking needle safe in recycling

Abstract

The invention discloses a blood taking needle safe in recycling. The blood taking needle comprises a blood taking needle body, a connecting tube and a vacuum tube. The blood taking needle body is arranged on a needle base. The symmetrical positions on the two sides of the needle base are respectively provided with a fin. The bottom of the needle base is connected with the connecting tube. The connecting tube is sleeved with a protection cover. The protection cover is composed of a hard casing pipe handle and a casing pipe capable of containing the blood taking needle body. The casing pipe is provided with a sliding groove matched with the fins. The casing pipe handle is provided with a limiting groove communicated with the sliding groove. The width of the sliding groove gradually becomes smaller from a needle head to the needle base. The width of the part, at the joint of the sliding groove and the limiting groove, of the sliding groove is smaller than that of the limiting groove. The limiting groove is slightly higher than the fins. The blood taking needle is simple and ingenious in structure, the limiting groove is ingeniously formed in the handle made of hard materials, the opening in the lower end of the sliding groove is small, and the fins of the blood taking needle body are limited in the limiting groove; the blood taking needle is safe and reliable.

Description

technical field [0001] The purpose of the present invention is to provide a blood collection needle, specifically a safe recovery blood collection needle, which belongs to the technical field of medical devices. Background technique [0002] In clinical work, the occurrence of injection-related needlestick injuries is random and uncontrollable, and nursing staff is a high-risk group for needlestick injuries. The harms of unsafe injections to society include needle sticks after use and improper disposal of injection equipment after use, leading to the spread of infection in society. Standard prevention was proposed by the Centers for Disease Control and Prevention in the United States in 1995 and implemented in the United States in 1996. It was introduced in my country in 1999 and incorporated into the "Nosocomial Infection Management Standards (Trial)" issued by the Ministry of Health in 2000. The standard precautionary point of view is that: all patients' blood, body fluid...

AI Technical Summary

Problems solved by technology

The existing protective cover has a sleeve-type protective cover, which is difficult to fit on the needle and is easy to accidentally injure; there is also a sliding protective cover that moves from the tail of the needle to the needle head. Axial opening and stop protrusions, using the elasticity of the protective sleeve, the needle-holding fins slide in and get stuck under the stop protrusions to play a protective role, but the material of this protective sleeve is soft, and the fins are easy to come out

[0004] In addition, this blood collection needle also has the following defects: since the vacuum blood collection tube in the whole assembly is transparent, it is impossible to know in time whether the needle is stuck in the vein through the blood
