Automatic needle stacking mechanism for needle bodies of blood sampling needles

Abstract

The invention relates to an automatic needle stacking mechanism for needle bodies of blood sampling needles, which comprises a needle stacking die and a needle bin, wherein a plurality of needle stacking grooves are arranged on the needle stacking die; the needle stacking grooves are arranged in parallel; and notches of the needle stacking grooves are horizontally arranged upward. The automatic needle stacking mechanism is characterized in that at least one needle stacking wheel is arranged right above the needle stacking die; a spindle of each needle stacking wheel is parallel to the length direction of the needle stacking grooves; at least one single needle groove is arranged on the circumferential surface of each needle stacking wheel; the length direction of each single needle groove is parallel to the spindle of the corresponding needle stacking wheel; the groove bottom of each single needle groove is provided with an air hole; corresponding to each air hole, an air flue is arranged in a wheel body of a needle stacking wheel; the needle bin is used for accommodating the needle bodies; and the circumferential surface of the needle bin, which is toward the needle stacking wheel, is provided with a needle outlet. The needle stacking mechanism can be used for automatically stacking the needle bodies on the needle stacking die, has high efficiency and high quality and is labor-saving.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a blood collection needle, which is suitable for stacking the needle body in the needle core of the blood collection needle on a coding needle mold before injection molding. Background technique [0002] During clinical examination, it is necessary to use blood collection to carry out micro blood collection for minimally invasive wounds at the end of human skin, and now more disposable blood collection needles are used. See attached figure 1 As shown: the disposable blood collection needle mainly includes a shell 27, a needle core and a spring 28, wherein the needle core is composed of a needle body 18 and a needle handle 25, and the tail of the needle body 18 is bent and injected into the needle handle 25, and the needle body 18 There is a protective rod 26 injection molded outside the needle point, and the protective rod 26 is separated from the needle point to expose the needle...

AI Technical Summary

Problems solved by technology

At present, the operation of the code needle is done manually by the operator, but the efficiency of the manual code needle is low, and because the manual code needle is labor-intensive, the operator needs to check the position of the needle body, the orientation of the needle tip, etc. Long-term work will inevitably lead to problems such as the needle body not being coded in place, missing codes or repeated codes on the code needle mold, and the needle tip is facing the wrong direction.
