Problems solved by technology

Assembly, leak testing, packaging and other process steps are relatively independent processes. Between each process, parts need to be turned back and forth, which is time-consuming, labor-intensive, low in production efficiency, and high in labor costs.
There are still many deficiencies in the overall manufacturing process design of the product

Embodiment Construction

[0010] From figure 1 As can be seen in the figure, an infusion set assembly process includes four steps: catheter extrusion, fitting assembly, leak detection, and packaging.

[0011] The catheter of the present invention is directly wound after being extruded and cut by the extruder 1, and shaped with rubber strips, and the catheter remains in a wound state during the assembly of accessories, leak detection, and packaging operations. The accessories assembly is to directly assemble the assembled piercer, dripping funnel, flow regulator, and semi-finished accessories of the liquid medicine filter on the catheter. After leak detection, the catheter is connected to other accessories and is directly packaged and bagged into an infusion set product. Such as figure 2 shown. When packaging, the product accessories are wound into a circle product along the direction of the circle around which the catheter is wound, and then packed into bags.

[0012] Such as figure 1 Shown, extr...

Abstract

The invention relates to an infusion apparatus assembly process, which comprises four steps of conduit extrusion, accessory assembly, leakage detection and packaging. The accessory assembly is that assembled semi-finished accessories such as a puncture outfit, a drop funnel, a flow regulator and a liquid medicine filter are directly assembled on a conduit; and after extrusion and cutting, the conduit is directly wound, is shaped by a tape and always keeps the winding state in the operating processes of accessory assembly, leakage detection and packaging. After the leakage detection, the conduit is communicated with other accessories and then is directly packaged into a bag to form an infusion apparatus product. The process effectively combines conduit extrusion, cutting, winding, assembly, leakage detection and packaging, reduces the turnover to and fro between various working procedures, reduces overstocked products of the various working procedures, and has the advantages of high production efficiency and reliable work.

Description

technical field [0001] The invention relates to a manufacturing process of a medical device, in particular to an assembly process of an infusion set. Background technique [0002] We know that a disposable infusion set is a commonly used medical device, which generally includes a puncture device, a drip funnel, a flow regulator, and a liquid medicine filter, and they are connected in series by a catheter. In the processing field of infusion sets, the overall assembly process of infusion sets includes several major process steps such as traditional assembly, leak testing, and packaging. With the emergence of more and more mechanization and automation equipment, the processing technology is becoming more and more simplified and more and more automated. But at present, it is the automation of individual components, such as automatic extrusion of catheters, automatic injection molding of accessories, etc. At present, the extruded catheter is cut to a certain length, and then s...
