Assembly device of butterfly wing type blood collection needle

Abstract

The invention discloses an assembly device of a butterfly wing type blood collection needle. The assembly device comprises an installation support and butterfly wing type blood collection needle assembly work stations installed on stations of the installation support respectively. The installation support is provided with a driving rotary plate and cam driving mechanisms used for driving the rotary plates to move along the butterfly wing type blood collection needle assembly work stations in a stepping mode and driving the butterfly wing type blood collection needle assembly work stations to work synchronously. The stepping rotary output ends of the cam driving mechanisms are connected with and drive the driving rotary plates. The butterfly wing type blood collection needle assembly work stations are sequentially distributed in the circumferential directions of the driving rotary plates. Each butterfly wing type blood collection needle assembly work station corresponds to one carrier, used for conveying butterfly wing type blood collection needle assembly materials, on the corresponding driving rotary plate, and the cam driving mechanisms drive different butterfly wing type blood collection needle assembly work stations to work due to the fact that different cam combinations output driving force at different frequencies. Assembly of the butterfly wing type blood collection needle is achieved in a pure mechanical and automatic mode.

Description

technical field [0001] The invention relates to the technical field of medical device manufacturing and assembly, in particular to an assembly device for a butterfly-wing blood collection needle. Background technique [0002] The basic operation of the butterfly-wing blood collection needle is similar to the traditional syringe blood collection, and its effect is better than that of the syringe. The butterfly-wing blood collection needle is suitable for patients of different ages, and is suitable for different parts. When puncturing blood vessels, it is smooth and easy, and the blood returns quickly and sensitively. It can be used to collect blood samples first, and then connected to the infusion system for intravenous infusion therapy, thereby reducing the pain of patients. The flexible extension tube of the butterfly-wing blood collection needle can keep the connection head away from the puncture point, which is convenient for changing the test tube. Therefore, it is wi...
