Medical device for aligning active-face of needle-tube

Abstract

The present invention provides a medical needle blade face aligning apparatus, pertains to medical machine technology field. The invention resolves technical problems that poor positioning of needle tube blade angle, low production efficiency etc. of prior medical needle blade face aligning apparatus. The medical needle blade face aligning apparatus comprises a base and a vibrator arranged on thebase, a positioning base is fixed on the vibrator, a plurality of grooves capable of placing medical needle blades are arranged on the positioning base, a profiling mechanism capable of positioning all blade faces of the needle tube inserted into the medical needle blade on the positioning base in a same direction is arranged on the base. The invention has advantages of simple structure, quick and accurate positioning, improved product quality and reduced production cost.

Description

technical field [0001] The invention belongs to the technical field of medical machinery and relates to a medical aiming blade surface device. Background technique [0002] In the medical device industry, medical needles are widely used, such as indwelling needles and venous needles. Currently used medical needles are composed of needle tubes, needle holder handles and the like. Taking the venous needle as an example, there is a cutting edge at the tip of the needle tube. When in use, the sharp part of the needle tip is close to the skin of the human body, and the hand-held piece is fixed on the side of the tail end of the needle tube. When puncturing, pinch the hand-held piece tightly with your hands, and the edge of the tip is upwards, which is conducive to puncturing. If the edge of the tip is downward, it is difficult to puncture. Therefore, when making the needle tube of the medical needle, it is necessary to keep the cutting edge of the tip and the handle of the need...

Problems solved by technology

[0003] At present, when assembling the needle tube and the needle seat handle, there is no special needle tube edge positioning device for medical needles to assist, all need to be done manually, and it is easy to cause the angle between the needle tube and the needle seat handle of the medical needle during the assembly process. Deviation occurs, resulting in product scrap

In addition, manual direct participation in the positioning of the needle edge of the medical needle will cause pollution, make it adhere to germs, and result in unqualified product hygiene requirements

On the other hand, this manual correction method will also affect the entire assembly process, resulting in low work efficiency and difficulty in adapting to the fierce market competition.

[0004] In order to improve work efficiency and reduce product pollution, various automatic assembly machines have been designed, but these automatic assembly machines are not suitable for the positioning of the needle tube direction of medical needles
