Abstract

The invention discloses an assembly method of a butterfly wing type blood taking needle. The assembly method is applied to a blood taking needle assembly system. The blood taking needle assembly system comprises a needle handle mounting station, a needle insertion station, an angle detection station, a sleeve mounting station and a rotary disc. The blood taking needle comprises a needle head, a needle handle and a sleeve. The assembly method of the butterfly wing type blood taking needle comprises the steps of inserting the needle handle into a locating hole of a carrier carried by the rotary disc to locate the needle handle through adopting the needle handle mounting station; inserting the needle head into the needle handle located on the carrier through the needle insertion station; adjusting the angle of the needle head inserted into the needle handle through utilizing the angle detection station, so as to ensure that an included angle between a detection surface on the needle head inserted into the needle handle and a reference surface on the needle handle meets the design requirement; and mounting the sleeve on the needle handle of which the needle head angle is adjusted through utilizing the sleeve mounting station. According to the assembly method of the butterfly wing type blood taking needle provided by the invention, all procedures of assembly of the blood taking needle can be automatically achieved, full-automatic assembly of the blood taking needle is achieved, and the assembly efficiency and reliability are improved.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular, to a method for assembling a butterfly-wing blood sampling needle. Background technique [0002] The blood sampling needle is mainly used to collect blood samples for examination of the blood samples, so as to understand the physiological and pathological conditions of the human body, and to facilitate the judgment of diseases. Butterfly-wing blood collection needles are widely used in the medical industry because they are smooth and easy to see blood return when puncturing blood vessels, and are suitable for patients of different ages and for different parts. [0003] At present, due to the small size of the butterfly-wing lancet, when performing the mechanized assembly of the butterfly-wing lancet, each station is generally equipped with independent process equipment and a dedicated drive device to align the butterfly-wing lancet. The lancet is assembled manually or semi-automa...
