Embodiment Construction

[0025] The structure and working principle of the needle recovery device of the present invention will be explained below by taking the recovery of a blood collection needle as an example with reference to the accompanying drawings. However, those skilled in the art should understand that the present invention is not limited to recovering blood collection needles, and can also be applied to other needles that need to be recovered.

[0026] figure 1 is a sectional view of the needle recovery device of the present invention before recovery starts. The illustrated needle recovery device includes a needle holder assembly 1 and a recovery tube assembly 2 . Needle holder assembly 1 includes for fixing blood collection needle 3 (see Figures 14 to 17 ) joint 10 and a hollow needle holder barrel 11 and a joint seat 12 formed at one end (front end, left end in the figure) of the needle holder barrel 11 for detachably fixing the joint 10 .

Abstract

A needle recovery device, comprising a needle holder assembly (1) which recovers a needle, and a recovery tube assembly (2). The needle holder assembly (1) comprises a connector (10), a needle holder cylinder (11), a connector base (12), a first separation component (14), and an engagement component (105) formed on the connector (10). The recovery tube assembly (2) comprises an external recovery tube (20), an internal recovery tube (21), a compression spring (22), a slide piece (23), a piston rod component (24), and an engagement component (246) formed on the piston rod component (24). The needle recovery device prevents a needle from causing accidental stab wounds after a blood sample has been taken. Also provided are the needle holder assembly (1), and the recovery tube assembly (2).

Description

technical field [0001] The invention relates to a needle recovery device and a needle holder assembly and a recovery tube assembly for needle recovery. Background technique [0002] It is an extremely common medical practice to analyze and judge the health condition or cause of disease of subjects such as people through blood tests. For this reason, it is first necessary to collect, for example, venous blood of the subject through a blood collection device. A typical blood collection device includes a blood collection needle, a needle holder and a vacuum blood collection tube capable of automatically drawing blood through the blood collection needle. When taking blood, first fix the blood collection needle to the joint seat of the needle holder through the joint, then perform venipuncture on the subject, and then install the vacuum blood collection tube into the needle holder, so the venous blood is vacuumed in the vacuum blood collection tube Under the action of the actio...
