An uncoated weld wire hypotube with HUB is a medical device component that combines a stainless steel hypotube, a welded distal wire, and an integrated moulded HUB. This configuration creates a ready-to-assemble component with a defined connection interface and a bare stainless steel tube surface.
The Weld Wire Hypotube without Coating with HUB from Nanos Biomaterial (Suzhou) Co., Ltd. is designed for applications such as simple delivery systems and diagnostic tools.
Main Components of an Uncoated Weld Wire Hypotube with HUB
The structure consists of several integrated elements, with the stainless steel hypotube, welded distal wire, and moulded HUB forming the main configuration.
1. Stainless Steel Hypotube
The hypotube is the main tubular component of the assembly. The material options include 304 and 316L stainless steel.
The tube has a bare stainless steel surface without an additional coating. This distinguishes the configuration from hypotubes that use surface coatings such as PTFE.
As the main tubular section, the hypotube forms the central structure connecting the proximal HUB with the distal welded wire.
2. Welded Distal Wire
A welded distal wire is integrated with the end of the hypotube.
The welded wire is an important feature of this configuration because it differentiates a weld wire hypotube from other hypotube structures. The wire is connected to the hypotube through welding to form the distal section of the component.
The quality and consistency of the welded connection are important considerations when producing this type of medical component.
3. Integrated Moulded HUB
The proximal end incorporates an integrated moulded HUB.
The HUB is made from medical-grade polymer and is designed to facilitate connection and ergonomic handling. It can provide a connection interface for components such as syringes or manifolds.
The molded construction integrates the HUB with the hypotube, creating a compact assembly that can be supplied as a ready-to-assemble component.
What Does “Uncoated” Mean?
In an uncoated weld wire hypotube, the stainless steel tube does not have an additional surface coating.
The configuration uses bare stainless steel rather than a coated surface. This characteristic distinguishes an uncoated weld wire hypotube from configurations that incorporate additional surface coatings.
The selection of an uncoated or coated structure should be based on the requirements of the finished medical device and its assembly conditions.
How the Components Are Arranged
The basic structure can be understood as:
Moulded HUB → Stainless Steel Hypotube → Welded Distal Wire
Each component occupies a different section of the assembly.
The HUB provides the connection interface at the proximal end. The stainless steel hypotube forms the central tubular section. The welded distal wire extends from the opposite end and is connected to the hypotube through welding.
Together, these components form an integrated weld wire hypotube assembly.
Material Configuration
The material configuration includes:
304/316L stainless steel tube
Medical-grade polymer HUB
Bare stainless steel surface
Welded distal wire
The stainless steel tube provides the main metallic structure, while the medical-grade polymer is used for the molded HUB.
Keeping these materials and their respective positions clear is important when evaluating the overall structure of the component.
Role of the HUB
The HUB is more than an external attachment. Its integrated molded design provides a defined connection area for the assembly.
The HUB supports easy connection and ergonomic handling, with connection applications including syringes or manifolds.
For medical device assembly, the HUB provides the interface between the hypotube component and other connected components.
