The invention discloses a butterfly-wing type blood collection needle assembly method, which is applied in a blood collection needle assembly system. The blood collection needle assembly system includes a needle handle installation station, a needle insertion station, an angle detection station, a sheath installation station and a rotating turntable. Including the needle head, the needle handle and the sheath, the assembly method of the butterfly-wing type blood collection needle includes the steps of: using the needle handle installation station to insert the needle handle into the positioning hole of the carrier carried by the rotating turntable to position the needle handle; The needle head is inserted into the needle handle that has been positioned on the carrier; the angle of the needle head that has been inserted into the needle handle is adjusted by using the angle detection station so that the detection surface on the needle head that has been inserted into the needle handle is consistent with the angle on the needle handle The included angle between the reference planes meets the design requirements; the sheath installation station is used to fit the sheath to the needle handle whose angle of the needle has been adjusted. The method for assembling the butterfly-wing blood collection needle provided in this embodiment can automatically complete each process of blood collection needle assembly, realize automatic assembly of the blood collection needle, and improve assembly efficiency and reliability.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a method for assembling a butterfly-wing blood collection needle. Background technique [0002] Blood collection needles are mainly used to collect blood samples for testing blood samples, so as to understand the physiological and pathological conditions of the human body, and to make judgments on diseases. Butterfly-wing blood collection needles are widely used in the medical industry because they are smooth and easy to puncture blood vessels, see blood return quickly and sensitively, and are suitable for patients of different ages and different parts. [0003] At present, due to the small size of the butterfly-wing blood collection needle, when the mechanized assembly of the butterfly-wing blood collection needle is generally carried out, each station is equipped with independent process equipment and a dedicated drive device for the butterfly-wing blood collection needle. The...
